Aristotle: Ethics


The surviving works of Aristotle include three treatises on moral philosophy: the Nicomachean Ethics in 10 books, the Eudemian Ethics in 7 books, and the Magna moralia (Latin: “Great Ethics”). The Nicomachean Ethics is generally regarded as the most important of the three; it consists of a series of short treatises, possibly brought together by Aristotle’s son Nicomachus. In the 19th century the Eudemian Ethics was often suspected of being the work of Aristotle’s pupil Eudemus of Rhodes, but there is no good reason to doubt its authenticity. Interestingly, the Nicomachean Ethics and the Eudemian Ethics have three books in common: books V, VI, and VII of the former are the same as books IV, V, and VI of the latter. Although the question has been disputed for centuries, it is most likely that the original home of the common books was the Eudemian Ethics; it is also probable that Aristotle used this work for a course on ethics that he taught at the Lyceum during his mature period. The Magna moralia probably consists of notes taken by an unknown student of such a course.

Happiness

Aristotle’s approach to ethics is teleological. If life is to be worth living, he argues, it must surely be for the sake of something that is an end in itself—i.e., desirable for its own sake. If there is any single thing that is the highest human good, therefore, it must be desirable for its own sake, and all other goods must be desirable for the sake of it. One popular conception of the highest human good is pleasure—the pleasures of food, drink, and sex, combined with aesthetic and intellectual pleasures. Other people prefer a life of virtuous action in the political sphere. A third possible candidate for the highest human good is scientific or philosophical contemplation. Aristotle thus reduces the answers to the question “What is a good life?” to a short list of three: the philosophical life, the political life, and the voluptuary life. This triad provides the key to his ethical inquiry.

“Happiness,” the term that Aristotle uses to designate the highest human good, is the usual translation of the Greek eudaimonia. Although it is impossible to abandon the English term at this stage of history, it should be borne in mind that what Aristotle means by eudaimonia is something more like well-being or flourishing than any feeling of contentment. Aristotle argues, in fact, that happiness is activity of the rational soul in accordance with virtue. Human beings must have a function, because particular types of humans (e.g., sculptors) do, as do the parts and organs of individual human beings. This function must be unique to humans; thus, it cannot consist of growth and nourishment, for this is shared by plants, or the life of the senses, for this is shared by animals. It must therefore involve the peculiarly human faculty of reason. The highest human good is the same as good human functioning, and good human functioning is the same as the good exercise of the faculty of reason—that is to say, the activity of rational soul in accordance with virtue. There are two kinds of virtue: moral and intellectual. Moral virtues are exemplified by courage, temperance, and liberality; the key intellectual virtues are wisdom, which governs ethical behaviour, and understanding, which is expressed in scientific endeavour and contemplation.

Virtue

People’s virtues are a subset of their good qualities. They are not innate, like eyesight, but are acquired by practice and lost by disuse. They are abiding states, and they thus differ from momentary passions such as anger and pity. Virtues are states of character that find expression both in purpose and in action. Moral virtue is expressed in good purpose—that is to say, in prescriptions for action in accordance with a good plan of life. It is expressed also in actions that avoid both excess and defect. A temperate person, for example, will avoid eating or drinking too much, but he will also avoid eating or drinking too little. Virtue chooses the mean, or middle ground, between excess and defect. Besides purpose and action, virtue is also concerned with feeling. One may, for example, be excessively concerned with sex or insufficiently interested in it; the temperate person will take the appropriate degree of interest and be neither lustful nor frigid.

While all the moral virtues are means of action and passion, it is not the case that every kind of action and passion is capable of a virtuous mean. There are some actions of which there is no right amount, because any amount of them is too much; Aristotle gives murder and adultery as examples. The virtues, besides being concerned with means of action and passion, are themselves means in the sense that they occupy a middle ground between two contrary vices. Thus, the virtue of courage is flanked on one side by foolhardiness and on the other by cowardice.

Aristotle’s account of virtue as a mean is no truism. It is a distinctive ethical theory that contrasts with other influential systems of various kinds. It contrasts, on the one hand, with religious systems that give a central role to the concept of a moral law, concentrating on the prohibitive aspects of morality. It also differs from moral systems such as utilitarianism that judge the rightness and wrongness of actions in terms of their consequences. Unlike the utilitarian, Aristotle believes that there are some kinds of action that are morally wrong in principle.

The mean that is the mark of moral virtue is determined by the intellectual virtue of wisdom. Wisdom is characteristically expressed in the formulation of prescriptions for action—“practical syllogisms,” as Aristotle calls them. A practical syllogism consists of a general recipe for a good life, followed by an accurate description of the agent’s actual circumstances and concluding with a decision about the appropriate action to be carried out.

Wisdom, the intellectual virtue that is proper to practical reason, is inseparably linked with the moral virtues of the affective part of the soul. Only if an agent possesses moral virtue will he endorse an appropriate recipe for a good life. Only if he is gifted with intelligence will he make an accurate assessment of the circumstances in which his decision is to be made. It is impossible, Aristotle says, to be really good without wisdom or to be really wise without moral virtue. Only when correct reasoning and right desire come together does truly virtuous action result.

Virtuous action, then, is always the result of successful practical reasoning. But practical reasoning may be defective in various ways. Someone may operate from a vicious choice of lifestyle; a glutton, for example, may plan his life around the project of always maximizing the present pleasure. Aristotle calls such a person “intemperate.” Even people who do not endorse such a hedonistic premise may, once in a while, overindulge. This failure to apply to a particular occasion a generally sound plan of life Aristotle calls “incontinence.”

Action and contemplation

The pleasures that are the domain of temperance, intemperance, and incontinence are the familiar bodily pleasures of food, drink, and sex. In treating of pleasure, however, Aristotle explores a much wider field. There are two classes of aesthetic pleasures: the pleasures of the inferior senses of touch and taste, and the pleasures of the superior senses of sight, hearing, and smell. Finally, at the top of the scale, there are the pleasures of the mind.

Plato had posed the question of whether the best life consists in the pursuit of pleasure or the exercise of the intellectual virtues. Aristotle’s answer is that, properly understood, the two are not in competition with each other. The exercise of the highest form of virtue is the very same thing as the truest form of pleasure; each is identical with the other and with happiness. The highest virtues are the intellectual ones, and among them Aristotle distinguished between wisdom and understanding. To the question of whether happiness is to be identified with the pleasure of wisdom or with the pleasure of understanding, Aristotle gives different answers in his main ethical treatises. In the Nicomachean Ethics perfect happiness, though it presupposes the moral virtues, is constituted solely by the activity of philosophical contemplation, whereas in the Eudemian Ethics it consists in the harmonious exercise of all the virtues, intellectual and moral.


The Eudemian ideal of happiness, given the role it assigns to contemplation, to the moral virtues, and to pleasure, can claim to combine the features of the traditional three lives—the life of the philosopher, the life of the politician, and the life of the pleasure seeker. The happy person will value contemplation above all, but part of his happy life will consist in the exercise of moral virtues in the political sphere and the enjoyment in moderation of the natural human pleasures of body as well as of soul. But even in the Eudemian Ethics it is “the service and contemplation of God” that sets the standard for the appropriate exercise of the moral virtues, and in the Nicomachean Ethics this contemplation is described as a superhuman activity of a divine part of human nature. Aristotle’s final word on ethics is that, despite being mortal, human beings must strive to make themselves immortal as far as they can.

Spinoza's Political Philosophy



Spinoza was a penetrating political theorist whose writings have enduring significance. In his two political treatises, Spinoza advances a number of forceful and original arguments in defense of democratic governance, freedom of thought and expression, and the subordination of religion to the state. On the basis of his naturalistic metaphysics, Spinoza also offers trenchant criticisms of ordinary conceptions of right and duty. And his account of civil organization, grounded in psychological realism, stands as an important contribution to the development of constitutionalism and the rule of law.

Despite being perhaps the most tolerant country in early-modern Europe—a sanctuary for free thinkers and members of religious minorities—the United Provinces were riven by religious conflict, as the Dutch sought to establish their identity after gaining independence from Spain. The confessional rifts of the seventeenth century were certainly an important part of context in which Spinoza composed his Tractatus Theologico-Politicus [hereafter: TTP].
The early part of the seventeenth century was marked by a religious schism that rapidly took on political significance. In 1610, forty-four followers of liberal theologian Jacobus Arminius—referred to as Arminians—wrote a formal “Remonstrance,” which articulated the ways in which they deviated from orthodox Calvinism, particularly with respect to the issues of self-determination and grace. The Arminians, or Remonstrants, defended religious toleration on the grounds that faith is expressed in the conscience of the individual, and so is not subject to the coercive power of the state. The doctrinal and political views of the Remonstrants were opposed by the conservative Gomarists (followers of Franciscus Gomarus), or Counter-Remonstrants. For a little over a decade (roughly 1607–1618), the dispute raged on, expanding outward from Holland and Utrecht. Finally, in 1618, a national synod convened (the Synod of Dort) to define more clearly the public faith. The fallout from the Synod of Dort was disastrous for the tolerant Arminians. The Advocate of the States of Holland, Johan Oldenbarnevelt, who staunchly defended the Remonstrants, was put to death. And Arminians throughout the country were purged from town councils and universities (Israel 1995, 452ff).

The second half of the century witnessed its own major theologico-political dispute in the United Provinces. At the center, once again, were two theologians: Johannes Cocceius, a liberal theology professor at Leiden, and Gisbertus Voetius, Dean of the University of Utrecht. Disputes between Cocceian and Voetians began over abstruse theological matters, but developed into a larger political and cultural affair. The Voetians led the assault on the Cartesian philosophy being taught in the universities. They thought that the new science advocated by Descartes, with its mechanistic view of the material world, posed a threat to Christianity in a variety of ways (Nadler 1999, 151–2 and 308–310). Spinoza's philosophy was reviled not only by the Voetians, but also by moderate Cocceian-Cartesians, who sought to distance themselves from radicals.

Spinoza was no stranger to religious persecution. As is well known, he was himself excommunicated from the Jewish community in Amsterdam in 1656. While Spinoza apparently endured the excommunication with characteristic equanimity, fellow Dutch apostate Jew, Uriel da Costa, was unable to bear the indignity of excommunication from the Amsterdam Jewish community. In 1640—when Spinoza was only eight years old—da Costa, who had denied the immortality of the soul and challenged the status of the Torah as divine revelation, took his own life.

Da Costa's suicide surely made a lasting impression on Spinoza, but it did not affect him as personally as did the treatment of his friend Adriaan Koerbagh at the hands of Dutch authorities in the years leading up to the publication of the TTP. In 1668 Koerbagh published two treatises that provoked the wrath of the Calvinist clergy. In the more scandalous of the two—Een Bloemhof van allerley lieflijkheyd (A Flower Garden of all Kinds of Loveliness)—Koerbagh ridiculed a number of traditional religious doctrines and practices, and, in the process, articulated his own religious and metaphysical views. Among the shocking views that he advanced were that Jesus is not divine, that God is identical with nature, that everything is necessitated by the laws of nature (the laws of God), and that miracles are impossible. These are all positions that Spinoza consistently endorsed. However, while Spinoza was famously cautious, Koerbagh was not, publishing the works in Dutch (thereby making them accessible to the general literate public) under his own name. Consequently, Koerbagh was tried and sentenced on charges of blasphemy. During his subsequent imprisonment under squalid conditions Koerbagh became ill, and he died soon thereafter (in 1669). It is generally supposed that it was Koerbagh's imprisonment and death above all else that precipitated the publication of the TTP (Nadler 1999, 170).


Spinoza's political thought draws from a number of sources, both classical and modern. As one commentator puts it, “Spinoza formed new conclusions from facts and concepts borrowed from others” (Haitsma Mulier 1980, 170). It is worth briefly considering some of the sources of the “facts and concepts” that he inherits.

At some point in the mid-1650's (around the time of his cherem, or excommunication) Spinoza began studying Latin with Franciscus Van den Enden. Van den Enden was an ex-Jesuit and radical egalitarian with revolutionary tendencies. He was put to death in 1674 after having been found guilty of conspiring to depose Louis XIV in order to establish a free republic in Normandy. Van dan Enden was an anti-clerical democrat who appears to have profoundly influenced Spinoza. One commentator has gone so far as to call Van den Enden “the genius behind Spinoza,” claiming that Van den Enden's writings “contain a political theory which is in fact the same as the one worked out by Spinoza” (Klever 1996, 26). Whether or not this assessment is fair, it is clear that Spinoza's thinking was nourished through his association with Van den Enden and the larger radical Cartesian circle in Amsterdam (Nyden-Bullock 2007).

Hobbes' influence on Spinoza is unmistakable. We know that Spinoza read De Cive carefully and that it was among his possessions when he died in 1677. He might also have read Leviathan, which appeared in Latin in 1668, as Spinoza was completing the TTP, although we do not know this for sure (Sacksteder 1980). I will discuss Spinoza's work in relationship to Hobbes' in some detail below (sections 2.1 and 2.2, below). Here I want to mention the impact of Dutch Hobbesians on Spinoza. Hobbesian thought was introduced into Dutch political discourse by Lambert van Velthuysen, an anti-clerical, liberal physician (Tuck 1979; Blom 1995). Velthuysen's Dissertatio is an unabashed defense of Hobbes' thought, in which the duty to preserve oneself is given pride of place (esp. Sect. XIII). Spinoza read and admired Velthuysen as a “man of exceptional sincerity of mind,” and was thus disconcerted when Velthuysen denounced the TTP as the work of a cunning atheist (Epistles 42 and 43).

Aside from Velthuysen, the other primary Dutch conduits for Hobbesian thought prior to Spinoza were the De la Court brothers (Petry 1984; Kossman 2000). Most of the De la Courts' writings were published by Pieter De la Court after the death of his brother Johan in 1660. However, because it remains unclear how much Pieter added and how much he profited off his studious younger brother, I will refer to these authors of these writings simply as the De la Courts, so as to avoid attribution problems. The De la Courts were ardent republicans who maintained good relations with Johan De Witt. Indeed, De Witt is thought to have written two chapters in the second edition of their book Interest van Holland (see Petry 1984, 152). The De la Courts adopted the basic features of Hobbesian anthropology, but eschewed juridical concepts like “right” and “contract” (see Malcolm 1991, 548), opting to analyze the civil condition in terms of the competing interests of participants. According to them, the aim of the state is to ensure that the interests of rulers are tied to the interests of the ruled, which is possible only if one adopts a series of institutional measures, such as the use of blind balloting, the removal of hereditary posts, and the rotation of offices. Republics, they argued, will be marked by greater checks against self-interested legislation than monarchies (see Blom 1993). Spinoza evidently studied these works carefully; his institutional recommendations in the Tractatus Politicus [hereafter: TP] reflect his debt to the De la Courts (Petry 1984; Haitsma Mulier 1980).

It was likely the writings of the De la Courts that impressed upon Spinoza the perspicacity of Niccolo Machiavelli. The notion of balancing the interests of competing parties was ultimately derived from Machiavelli (see Haitsma Mulier 1993, 254–255). Spinoza's Political Treatise is shot through with Machiavellian insights and recommendations. Right at the outset of the work, Spinoza parrots Machiavelli's critique of utopian theorizing, elevating statesmen over philosophers, since only the latter begin with a realistic conception of human psychology (TP 1/1; cf. Machiavelli's Prince I.15). Machiavellian realism pervades Spinoza's political writings, playing a particularly large role in the constitutional theorizing of the TP. Spinoza, like Machiavelli, understood that prescriptions for improving the governance of a state can be offered only after one has a proper diagnosis of the problems and a proper grasp of human nature.

Basic Features of Spinoza's Political Philosophy

Three of the most striking and important claims of Spinoza's Ethics are that (1) all things come to exist and act necessarily from the laws of God's nature (e.g., EIP29 and EIP33), (2) nature does not act on account of some end or purpose (EI Appendix), and (3) nature is everywhere and always the same (EIII Preface). Collectively, these three claims entail that human behavior, like the behavior of everything else, is fully necessitated by, and explicable through, the immutable—and non-providential—laws of God or Nature. This forms a significant part of the metaphysical backdrop against which Spinoza develops his political theory. For the sake of simplicity, I will call the view that is constituted by these three theses Spinoza's naturalism. This naturalism led him to adopt radical views regarding the source and status of rights, obligations, and laws, distinguishing his work from other seventeenth-century political theorists.

Spinoza's naturalism excludes transcendental conceptions of God. Those who believe in a transcendent God “imagine that there are two powers, distinct from each other, the power of God and the power of natural things…. they imagine the power of God to be like the authority of royal majesty, and the power of nature to be like a force and impetus” (TTP 6/81). Of course, on Spinoza's account, God is not a transcendent legislator, God is nature itself. Spinoza's naturalism entails that all claims of entitlement deriving from God's will are specious. This is a direct rebuke not only of defenders of the divine right of kings, but also of most accounts of natural rights as entitlements that were embraced by many seventeenth-century theorists.

Moreover, this naturalism also rules out dualistic views of nature according to which there is a normative order of things, or a way that things should be, that stands in contrast to the actual order of things. This view undermines the teleological assumptions that form the basis of natural law theory, whether Thomistic or Protestant. Even those who wished to separate natural law from theology (e.g., Pufendorf), and those who de-emphasized the role of God's will—as Grotius does in his famous etiam si daremus passage—still supposed that there is a way that things ought to be, a normative natural order that can be decoupled from the actual order of things. According to this view, humans act contrary to nature when they act contrary to the prescripts of right reason. Spinoza attacks this view, according to which “the ignorant violate the order of nature rather than conform to it; they think of men in nature as a state within a state [imperium in imperio]” (TP 2/6). The phrase “imperium in imperio” famously appears also in the preface to Ethics III, where Spinoza is characterizing the non-naturalist view that he opposes. In both of these passages, Spinoza criticizes the assumption that man is governed by his own set of rational, normative laws, rather than the laws that govern the rest of nature. It is precisely this position that Spinoza undercuts when he writes in the Ethics that “the laws and rules of Nature…are always and everywhere the same” (EIII preface) and in the TP that “whether man is led by reason or solely by desire, he does nothing that is not in accordance with the laws and rules of nature” (TP 2/5).

In short, by adopting the view that nature is univocal and that man is governed by the same laws as everything else in nature, Spinoza rejects the natural law tradition (Curley 1991; A. Garrett 2003; for contrasting views, see Kisner 2010 and Miller 2012). And even if Spinoza's naturalism is viewed as part of a larger naturalistic trend in Dutch political thought (Blom 1995), his disavowal of normative conceptions of nature and rejection of teleology indicates a clear break with tradition. To appreciate the depth and significance of Spinoza's naturalism, it will be helpful to compare his views on natural right and obligation to Hobbes'.


One of the most notorious features of Spinoza's political thought is his account of natural right. He introduces this concept in TTP 16, where he boldly writes:
By the right and order of nature I merely mean the rules determining the nature of each individual thing by which we conceive it is determined naturally to exist and to behave in a certain way. For example fish are determined by nature to swim and big fish to eat little ones, and therefore it is by sovereign natural right that fish have possession of the water and that big fish eat small fish. For it is certain that nature, considered wholly in itself, has a sovereign right to do everything that it can do, i.e., the right of nature extends as far as its power extends…since the universal power of the whole of nature is nothing but the power of all individual things together, it follows that each individual thing has the sovereign right to do everything that it can do, or the right of each thing extends so far as its determined power extends. (TTP 16, 195; cf. TP 2/4).
In claiming that the right of nature is coextensive with the power of nature and that the coextensivity of right and power applies mutatis mutandis to the individuals in nature, Spinoza is simply rejecting non-naturalism, rather than making a positive normative claim. So although Spinoza is often seen as subscribing to the view that “might makes right” (see Barbone and Rice 2000, 19; McShea 1968, 139), this is misleading in a sense, if it is taken as implying that Spinoza is redefining right in terms of power. In fact, I take it that the coextensivity thesis is not to be understood as offering a new normative standard; rather, it is intended as a denial of any transcendental standard of justice (see Curley 1996, 322; Balibar 1998, 59). To say that something is done by right in Spinoza's sense is just to say that there is nothing in virtue of which that action can be judged impermissible. So, even if Spinoza's account implies that Cortés conquered the Aztecs by right, it does not follow that it was necessarily the right, or proper, thing to do (see TP 5/1; see section 2.3).

Spinoza's brazen denial of natural proscriptions on what one can do roused the ire of early readers (e.g., Pufendorf 1934, 159). Of course, Thomas Hobbes, Spinoza's great predecessor, had made a similar claim. Indeed, Spinoza's account of natural right is often taken as evidence that he is a Hobbesian. Hobbes' account of natural right has been the subject of much interpretative dispute, in part because it seems to undergo a shift between his early political writings and Leviathan. In De Cive Hobbes defines right as “the liberty each man has of using his natural faculties in accordance with right reason” (1.7). In other words, natural right is the liberty to do anything consistent with the natural law (ibid. 2.1). This includes the right to do anything that one judges to be necessary for one's preservation (1.8–1.9). Hobbes adds one proviso here, which may be called the “sincerity clause,” namely that one violates the law of nature, or acts without right, when one acts in a way that one does not sincerely believe contributes to one's preservation (1.10n). And later Hobbes suggests that because “drunkenness and cruelty” cannot sincerely be thought to contribute to self-preservation, drunken and cruel actions are not performed by right, even in the state of nature (ibid., 3.27). In short, as A. G. Wernham puts it, on Hobbes' view, man's natural right “covers only some of his actions” (Wernham 1958, 14). Specifically, it covers those actions that are not contrary to the law of nature.
In Leviathan, however, Hobbes seems to advance an account of natural right that is apparently not bound by such normative constraints (Ch. 14). But while it may seem that in the later work Hobbes strips the concept of natural right of all normative content, even the view expressed in Leviathan may be seen to be at odds with a thoroughgoing naturalism. To see this, consider Spinoza's reply to his friend to Jarig Jelles, when asked what sets his views apart from Hobbes':
With regard to political theory, the difference between Hobbes and myself, which is the subject of your inquiry, consists in this, that I always preserve the natural right in its entirety [ego naturale jus semper sartum tectum conservo], and I hold that the sovereign power in a State has right over a subject only in proportion to the excess of its power over that of a subject. (Epistle 50)

What Spinoza is criticizing here is the Hobbesian view of contracts (covenants) or the transference of one's natural right. The transferability or alienability of one's natural right to judge how to defend oneself serves as the foundation of Hobbes' political theory; it allows him to explain the formation of the commonwealth and the legitimacy of the sovereign. In Spinoza's view, however, Hobbes violates naturalism here. By conceiving of one's natural right as something like an entitlement that can be transferred, which in turn leads him to drive a wedge between right and power in the commonwealth, Hobbes never fully rids his account of the vestiges of the juridical tradition that Spinoza sought to overturn.


The difference between Hobbes and Spinoza on right bears directly on their distinct accounts of obligation. Hobbes thinks that we incur binding obligations when we make pledges under the appropriate conditions. By contrast, Spinoza maintains that “the validity of an agreement rests on its utility, without which the agreement automatically becomes null and void” (TTP 16/182; cf. TP 2/12). To demand otherwise would be absurd, since men are bound by nature to choose what appears to be the greater good or lesser evil. We are bound by nature to act on our strongest interest and cannot be obligated by previous agreements to break this inviolable psychological law of nature.
By adhering to a strict naturalism about right and obligation and maintaining that “the sovereign power in a State has right over a subject only in proportion to the excess of its power over that of a subject” (Epistle 50), Spinoza, unlike Hobbes, places the burden of political stability on the sovereign rather than the subject (see Wernham 1958, 27). The commonwealth must be structured so as to promote compliance; when there is excessive vice or non-compliance, the blame must be “laid at the door of the commonwealth” (TP 5/3). So, whereas Hobbes argues that the sovereign is always vested with nearly absolute legislative authority, Spinoza claims that “since the right of a commonwealth is determined by the collective power of a people, the greater the number of subjects who are given cause by a commonwealth to join in conspiracy against it, the more must its power and right be diminished” (TP 3/9). If a sovereign is to maintain its right, it must legislate wisely, so as not to incite insurrection. So while Spinoza does not accord to the people a proper right of revolution, he proposes a naturalistic equivalent, since the right of the state is essentially constituted, and limited, by the power of the people (TP 2/17) (see Sharp 2013).
Thus, when Spinoza points to the differences between his view of natural right and Hobbes' in his letter to Jelles, differences that might appear negligible to the casual reader, he is identifying a significant distinction (see Wernham 1958, 35). Spinoza's thoroughgoing naturalism leads him to reject the sharp distinction that Hobbes draws between civil state—the product of artifice—and the state of nature, along with the concomitant conception of obligation that arises with the inception of the commonwealth. But given his naturalism and repudiation of rights and obligations as traditionally understood, one might be left wondering how or whether Spinoza could offer a normative political theory at all.


As Curley rightly points out, to deny that there is a transcendental standard of justice is not to deny that there is any normative standard by which we can evaluate action (Curley 1996). Even if one can act irrationally without violating nature that does not mean that all of one's actions have the same normative status. As Spinoza puts it, “it is one thing, I say, to defend oneself, to preserve oneself, to give judgment, etc., by right, another thing to defend and preserve oneself in the best way and to give the best judgment” (TP 5/1). The goodness of an action is to be judged in relation to whether the action aids one's striving to preserve and augment one's power (see EIVP18S; TP 2/8; TTP 16/181). The striving to preserve and augment one's power, which constitutes one's actual essence (EIIIP7), provides a standard for moral judgments: things are good or bad to the extent that they aid or diminish one's power of acting (Curley 1973). And just as the individual ought to do those things that maximize his or her own power or welfare, Spinoza takes it as axiomatic that the state ought to do those things that maximize the power of the people as a whole (e.g., TTP 16/184).

Spinoza's Argument for Toleration

Spinoza is often remembered for his contribution to the liberal tradition, due, in large part, to his defense of the freedoms of thought and speech in TTP 20. However, the tolerationism expressed in TTP 20 appears to stand in tension with the Erastian claim of TTP 19. How can Spinoza be a liberal about religious practice while also defending the view that the state maintains full right over matters of religion (TTP, Ch. 19)? Three things must be noted in response to this puzzle. First, unlike Locke's tolerationism, Spinoza's defense of civil liberties in TTP 20 is not fundamentally a defense freedom of worship (Israel 2001, 265–266). Rather, it is essentially a defense of the freedom to philosophize; freedom of worship is at best an incidental byproduct of this primary aim. Second, Spinoza sharply distinguishes between one's outward expressions of faith and one's inward worship of God. Sovereign authority over religious expression concerns only the former, leaving the latter the domain of the individual, for reasons that we will examine in a moment. Both of these positions can be understood as lending support to the Arminian cause against Calvinist Theocrats (Nadler 1999, 12). Finally, it should be mentioned that Spinoza's denial that freedoms concerning outward religious expression must be protected points to the limited nature of his brand of toleration. The sovereign retains full discretion to determine which actions are acceptable and what forms of speech are seditious. As Lewis Feuer ruefully notes, Spinoza does not offer anything resembling Oliver Wendell Holmes's standard of “clear and present danger” to constrain sovereign intervention (1987, 114).
What are Spinoza's arguments for his, albeit limited, defense freedoms of thought and speech? The first argument is that it is strictly impossible to control another's beliefs completely (20, 250–51). Since right is coextensive with power, lacking the power to control beliefs entails lacking the right to do so. However, since Spinoza admits that beliefs can be influenced in myriad ways, even if not fully controlled, this argument amounts to a rather restricted defense of freedom of conscience.
Next, the argument shifts from considering what the sovereign can do to what it would be practical or prudent for a sovereign to do. Spinoza offers a battery of pragmatic reasons in defense of non-interference. For instance, he argues that “a state can never succeed very far in attempting to force people to speak as the sovereign power commands” (20, 251). Men are naturally inclined to express what they believe (ibid.), and so just as attempts to regulate beliefs fail, so do attempts to regulate the expressions of these beliefs. Moreover, even if a state were to regulate speech, this would only result in the erosion of good faith [fides] on which civil associations depend, since men would be “thinking one thing and saying something else” (20, 255). It is thus foolish to seek to regulate all speech, even if it is also “very dangerous” to grant unlimited freedom of speech (20, 252).
Spinoza also argues that in general the more oppressively a sovereign governs, the more rebellious the citizens will be, since most people are “so constituted that there is nothing they would more reluctantly put up with than that the opinions they belief to be true should be outlawed” (20, 255). 

The source of oppression and the resistance to it have a common root on Spinoza's account, namely, ambition, or the desire for others to approve of the same things that we do (see EIIIP29; cf. Rosenthal 2001 and 2003). Men being constituted as they are, when differences of opinion arise—as they inevitably do—they are inclined to foist their standard on others and to resist others' attempts to do the same. So, however common attempts to regulate the beliefs, speech, and behavior of others may be, it is politically unstable to do so. Moreover, Spinoza argues that it is often the least wise and the most obnoxious who initiate moral crusades, and just as it is often the wisest and most peace-loving who are the targets of such campaigns (20, 256–58).

It is worth noting that these arguments in defense of civil liberties are thoroughly pragmatic; they rely on psychological principles and empirical observations to illustrate the instability and imprudence of oppressive governance (see Steinberg 2010b). They are not principled arguments that depend on rights or the intrinsic value of liberty, much to the frustration of some commentators (Feuer 1987; Curley 1996).

Social Contract in the TTP

A good deal of scholarly attention has been placed on Spinoza's account of the social contract in the TTP. Spinoza introduces the contract in Chapter 16, when considering how people escape the pre-civil condition. Here he claims that “[men] had to make a firm decision, and reach agreement, to decide everything by the sole dictate of reason” (16, 198), which requires, as he later makes clear, that each transfers one's right to determine how to live and defend himself to the sovereign (16, 199–200); cf. EIVP37S2). He also cites the establishment of the Hebrew state, with Moses as the absolute sovereign, as an historical example of a social contract (19, 240). The social contract seems to confer nearly boundless authority on the sovereign. So long as we are rational, “we are obliged to carry out absolutely all commands of the sovereign power, however absurd they may be” (16, 200).
However, if Spinoza really relies upon the social contract as a source of legitimacy, several problems arise. First of all, it seems unlikely that such a contract could ever have been formed, since the legitimating strength of a social contract seems to depend on the farsighted rationality of humans, and yet Spinoza clearly thinks that the majority of men are not generally rational (see Den Uyl 1983).
But even if such a contract were possible, a much greater problem remains for Spinoza. How can we take seriously a legitimacy-conferring contract without violating the naturalism that is at the core of Spinoza's metaphysics? What is this right that is surrendered or transferred? And how can one really transfer one's right, given the coextensivity of right and power? Moreover, Spinoza's naturalistic, utility-based account of obligation (see 2.2, above) seems to preclude the possibility of a binding social contract.

Some commentators take these problems with Spinoza's social contract to be insurmountable, and for this reason they regard him as coming to his senses when be abandons the contract in the TP (Wernham 1958, 25–27). Others have tried to reinterpret the contract in a way that is makes it consistent with his naturalism. For instance, Barbone and Rice distinguish between two concepts that have been rendered in English as “power.” On the one hand there is potentia, which is the power that is essential to the individual (Barbone and Rice 2000, 17). This power in inalienable. What is transferable is one's potestas, i.e. one's authority (Barbone and Rice 2000, 17) or coercive power (Blom 1995, 211).
While this interpretation has the virtue of cohering with Spinoza's claim that he “always preserve[s] the natural right in its entirety” (Epistle 50), since one's right, or potentia, always remains intact, it leaves unexplained how potestas, which Barbone and Rice describe as a “super-added” capacity, fits into the natural order. What can it mean to possess, transfer, or renounce one's potestas? And how can transferring or revoking it result in an obligation, given Spinoza's utility-based account of obligation?
The best way to understand what it means to possess or give up one potestas is in psychological terms. Curley suggests this when he looks to Hobbes' claim in Behemoth that the “the power of the mighty hath no foundation but in the opinion and belief of the people” (EW VI, 184, 237—cited in Curley 1996, 326) as a way of understanding Spinoza's conception of sovereign formation. One could also cite Hobbes' famous claim in Leviathan that “reputation of power is power” (Ch. 10) as an expression of the same point. These passages can be understood as supporting the view that power is not transferred by way of a speech act, but rather by standing in the psychological thrall of the sovereign. Sovereignty is the product of psychological deference rather than the formal transference of rights or titles. We may call this the psychological interpretation of the social contract.

Some evidence in support of the psychological interpretation comes in TTP 17, where Spinoza claims that sovereign power or authority derives from the will of its subjects to obey (17, 209–10; cf. TP 2/9–10). There are places in the text, however, when Spinoza seems to imply that we have obligations to the sovereign irrespective of our psychological or motivational state. In some of these instances, a careful reading reveals that nothing of the sort is implied. For instance, his claim that “we are obliged to carry absolutely all the commands of the sovereign power, however absurd they may be” (16, 200) is contingent on our behaving rationally and wanting to avoid being regarded as enemies of the state. Still, there are other places when he does imply that de facto obedience is neither necessary nor sufficient for establishing the legitimacy of a civil body. For instance, he claims that the sovereign alone has right over religious matters such as interpreting Scripture, excommunicating heretics, and making provisions for the poor (19, 239 - 40), despite the fact that the church had, in fact, been exercising power in these matters. But this too can be reconciled with Spinoza's naturalism, provided that we understand that the power or authority of clerics devolves upon them from the power or authority of the sovereign.

Aristotle : Matter and Form



Change, for Aristotle, can take place in many different categories. Local motion, as noted, is change in the category of place. Change in the category of quantity is growth (or shrinkage), and change in the category of quality (e.g., of colour) is what Aristotle calls “alteration.” Change in the category of substance, however—a change of one kind of thing into another—is very special. When a substance undergoes a change of quantity or quality, the same substance remains throughout. But does anything persist when one kind of thing turns into another? Aristotle’s answer is yes: matter. He says,

    “By matter, I mean what in itself is neither of any kind nor of any size nor describable by any of the categories of being. For it is something of which all these things are predicated, and therefore its essence is different from that of all the predicates.”

An entity that is not of any kind, size, or shape and of which nothing at all can be said may seem highly mysterious, but this is not what Aristotle has in mind. His ultimate matter (he sometimes calls it “prime matter”) is not in itself of any kind. It is not in itself of any particular size, because it can grow or shrink; it is not in itself water or steam, because it is both of these in turn. But this does not mean that there is any time at which it is not of any size or any time at which it is neither water nor steam nor anything else.

Ordinary life provides many examples of pieces of matter changing from one kind to another. A bottle containing a pint of cream may be found, after shaking, to contain not cream but butter. The stuff that comes out of the bottle is the same as the stuff that went into it; nothing has been added and nothing taken away. But what comes out is different in kind from what went in. It is from cases such as this that the Aristotelian notion of matter is derived.

Form

Although Aristotle’s system makes room for forms, they differ significantly from Forms as Plato conceived them. For Aristotle, the form of a particular thing is not separate (chorista) from the thing itself—any form is the form of some thing. In Aristotle’s physics, form is always paired with matter, and the paradigm examples of forms are those of material substances.

Aristotle distinguishes between “substantial” and “accidental” forms. A substantial form is a second substance (species or kind) considered as a universal; the predicate human, for example, is universal as well as substantial. Thus, Socrates is human may be described as predicating a second substance of a first substance (Socrates) or as predicating a substantial form of a first substance. Whereas substantial forms correspond to the category of substance, accidental forms correspond to categories other than substance; they are nonsubstantial categories considered as universals. Socrates is wise, for example, may be described as predicating a quality (wise) of a first substance or as predicating an accidental form of a first substance. Aristotle calls such forms “accidental” because they may undergo change, or be gained or lost, without thereby changing the first substance into something else or causing it to cease to exist. Substantial forms, in contrast, cannot be gained or lost without changing the nature of the substance of which they are predicated. In the propositions above, wise is an accidental form and human a substantial form; Socrates could survive the loss of the former but not the loss of the latter.

When a thing comes into being, neither its matter nor its form is created. When one manufactures a bronze sphere, for example, what comes into existence is not the bronze or the spherical shape but the shaped bronze. Similarly in the case of the human Socrates. But the fact that the forms of things are not created does not mean that they must exist independently of matter, outside space and time, as Plato maintained. The bronze sphere derives its shape not from an ideal Sphere but from its maker, who introduces form into the appropriate matter in the process of his work. Likewise, Socrates’ humanity derives not from an ideal Human but from his parents, who introduce form into the appropriate matter when they conceive him.


Thus, Aristotle reverses the question asked by Plato: “What is it that two human beings have in common that makes them both human?” He asks instead, “What makes two human beings two humans rather than one?” And his answer is that what makes Socrates distinct from his friend Callias is not their substantial form, which is the same, nor their accidental forms, which may be the same or different, but their matter. Matter, not form, is the principle of individuation.

Benedict De Spinoza, one of the great philosophers of modernity



(1632—1677)

Benedict de Spinoza  was among the most important of the post-Cartesian philosophers who flourished in the second half of the 17th century. He made significant contributions in virtually every area of philosophy, and his writings reveal the influence of such divergent sources as Stoicism, Jewish Rationalism, Machiavelli, Hobbes, Descartes, and a variety of heterodox religious thinkers of his day. For this reason he is difficult to categorize, though he is usually counted, along with Descartes and Leibniz, as one of the three major Rationalists. Given Spinoza’s devaluation of sense perception as a means of acquiring knowledge, his description of a purely intellectual form of cognition, and his idealization of geometry as a model for philosophy, this categorization is fair. But it should not blind us to the eclecticism of his pursuits, nor to the striking originality of his thought.

Among philosophers, Spinoza is best known for his Ethics, a monumental work that presents an ethical vision unfolding out of a monistic metaphysics in which God and Nature are identified. God is no longer the transcendent creator of the universe who rules it via providence, but Nature itself, understood as an infinite, necessary, and fully deterministic system of which humans are a part. Humans find happiness only through a rational understanding of this system and their place within it. On account of this and the many other provocative positions he advocates, Spinoza has remained an enormously controversial figure. For many, he is the harbinger of enlightened modernity who calls us to live by the guidance of reason. For others, he is the enemy of the traditions that sustain us and the denier of what is noble within us. After a review of Spinoza’s life and works, this article examines the main themes of his philosophy, primarily as they are set forth in the Ethics.

1. Life and Works

Spinoza came into the world a Jew. Born in 1632, he was the son of Marrano parents. They had immigrated to Amsterdam from Portugal in order to escape the Inquisition that had spread across the Iberian Peninsula and live in the relatively tolerant atmosphere of Holland. Spinoza's father, Michael, was a successful merchant and a respected member of the community. His mother, Hanna, the second of Michael's three wives, died in 1638, just before Spinoza was to turn six.

The young Spinoza, given the name Baruch, was educated in his congregation's academy, the Talmud Torah school. There he received the kind of education that the community deemed necessary to constitute one as an educated Jew. This largely consisted of religious study , including instruction in Hebrew, liturgy, Torah, prophetic writings, and rabbinical commentaries. Although Spinoza no doubt excelled in these, he did not move on to the higher levels of study which focused on the Talmud and were typically undertaken by those preparing for the rabbinate. Whether by desire or by necessity, Spinoza left the school in order to work in his father's business, which he eventually took over with his half-brother, Gabriel.

The Jewish community in Amsterdam was by no means a closed one , but Spinoza's commercial activities put him in touch with more diverse currents of thought than those to which he had hitherto been exposed. Most significantly, he came into contact with so-called 'free-thinking' Protestants - dissenters from the dominant Calvinism – who maintained a lively interest in a wide range of theological issues, as well as in the latest developments in philosophy and science. This naturally included the work of Descartes, which was regarded by many in Holland to be the most promising of several alternatives to scholasticism that had emerged in recent decades. In order to discuss their interests, these free-thinkers organized themselves into small groups, they called colleges, which met on a regular basis. Spinoza may have attended such meetings as early as the first half of the 1650's, and it is most likely here that he received his first exposure to Cartesian thought.

This is not to say that Spinoza ceased to mine the resources of his own tradition - he became steeped, for example, in the writings of such philosophically important figures as Maimonides and Gersonides - but his intellectual horizons were expanding and he was experiencing a restlessness that drove him to look further afield. It was at this time that he placed himself under the tutelage of an ex-Jesuit, Franciscus Van den Enden, who had recently set up a Latin school in Amsterdam. Van den Enden turned out to be the perfect teacher for Spinoza. In addition to having an excellent reputation as a Latinist, he was a medical doctor who kept abreast of all that was new in the sciences. He was also notorious for his allegedly irreligious cast of mind, and he was a passionate advocate of democratic political ideals. It is safe to say that Spinoza's studies with Van den Enden included more than lessons on how to decline nouns.

Spinoza's intellectual reorientation, however, came at a cost . His increasingly unorthodox views and, perhaps, laxity in his observance of the Jewish law strained his relations with the community. Tensions became so great that, in 1656, the elders of the synagogue undertook proceedings to excommunicate him. Without providing details, the writ of excommunication accuses him of 'abominable heresies' and ‘monstrous deeds’. It then levels a series of curses against him and prohibits others from communicating with him, doing business with him, reading anything he might write, or even coming into close proximity with him. Spinoza may still have been a Jew, but he was now an outcast.

Little is known about Spinoza's activities in the years immediately following his excommunication. He continued his studies with Van den Enden and occasionally took up residence in his teacher's home. As it was now impossible for him to carry on in commerce, it was most likely at this time that he took up lens grinding as an occupation. There is also evidence that he traveled periodically to Leiden to study at the university. There he would have received formal instruction in Cartesian philosophy and become familiar with the work of prominent Dutch Cartesians. In 1661, he settled near Leiden, in the town of Rijnsburg.

It was during this same period, in the late 1650's, that Spinoza embarked upon his literary career. His first work, the Treatise on the Emendation of the Intellect, is an attempt to formulate a philosophical method that would allow the mind to form the clear and distinct ideas that are necessary for its perfection. It contains, in addition, reflection upon the various kinds of knowledge, an extended treatment of definition, and a lengthy analysis of the nature and causes of doubt. For reasons that are unknown, theTreatise was left unfinished, though it appears that Spinoza always intended to complete it. Shortly thereafter, while in Rijnsburg, Spinoza set to work on his Short Treatise on God, Man, and His Well-Being. This work, circulated privately among friends, foreshadows many of the themes of his mature work, the Ethics. Most notably, it contains an unambiguous statement of the most famous of Spinoza's theses - the identity of God and Nature.

Spinoza's stay in Rijnsburg was brief. In 1663 he moved to the town of Voorburg, not far from The Hague, where he settled into a quiet, but busy, life. At the behest of friends, he immediately set about preparing for publication a set of lessons that he had given to a student in Leiden on Descartes'sPrinciples of Philosophy. The result was the only work that he was to publish under his own name, now Latinized to Benedict: René Descartes's Principles of Philosophy, Parts I and II, Demonstrated According to the Geometric Method by Benedict de Spinoza of Amsterdam. As a condition of publication, Spinoza had his friend, Lodewijk Meyer, write a preface to the work, warning the reader that his aim was exposition only and that he did not endorse all of Descartes's conclusions. He also appended a short piece, entitled Metaphysical Thoughts, in which he sketched some of his own views. Despite his admiration for Descartes, Spinoza did not want to be seen as a Cartesian.

Spinoza's work on Descartes shows him to have been interested from early on in the use of geometric method in philosophy. In addition to putting parts of the Principles into geometric form, he began experimenting with geometric demonstrations of material taken from his own Short Treatise. It was out of this experimentation that the idea arose for a fully geometric presentation of his thought. He began work on this sometime in the early 1660's, and by 1665 substantial portions of what was to become theEthics were circulating in draft form among his friends back in Amsterdam. Though he was well into the project by then, the political and religious climate of the day made Spinoza hesitant to complete it . He chose to exercise caution and suspended work on it, turning instead to a book that would prepare an audience receptive to the Ethics. This was the Theological-Political Treatise, which he completed and published anonymously in 1670.

Spinoza's aim in the Theological-Political Treatise was to argue that the stability and security of society is not undermined but, rather, enhanced by freedom of thought, meaning primarily the freedom to philosophize. As is clear from the text, he considered the primary threat to this freedom emanated from the clergy, whom he accused of playing upon the fears and superstitions of people in order to maintain power. His solution was to divest the clergy of all political power, even to the point of placing authority over the practice of religion in the hands of the sovereign. The sovereign, Spinoza argued, should extend broad liberties within this domain, requiring adherence to no more than a minimal creed that was neutral with respect to competing sects and the meaning of which was open to a variety of interpretations. This, he hoped, would allow philosophers the freedom to do their work unencumbered by the constraints of sectarianism.

As was to be expected, the Theological-Political Treatise was met with a firestorm of criticism. It was condemned as a work of evil, and its author was accused of having nefarious intentions in writing it. Even some of Spinoza's closest friends were deeply unsettled by it. Though he had assiduously tried to avoid it, Spinoza found himself embroiled in heated religious controversy and saddled with a reputation for atheism, something he greatly resented.

Spinoza's last move, in 1670, was to The Hague, where he was to live out his remaining years. Besides having to deal with fallout from his Theological-Political Treatise, he witnessed a political revolution that culminated in the murder of the Grand Pensionary of Holland, Jan De Witt, along with his brother, Cornelius, by an angry mob of Orangist-Calvinists. Spinoza admired De Witt for his liberal policies and was horrified at the murder. With the ascent of the Orangist-Calvinist faction, he felt his own situation to be tenuous.

Despite these distractions, Spinoza pressed on. He undertook new projects, including the writing of a Hebrew grammar, and he turned back to work on the Ethics. Given the hostility with which theTheological-Political Treatise was met and the realities of the new political landscape, he must have done so with a deep sense of pessimism about its chances for success. By 1675 it was complete. As he perceived his enemies to have grown in influence and opportunity, however, Spinoza decided against publishing it. Public viewing of the definitive statement of his philosophy would have to wait until after his death.

By this time Spinoza was in a state of failing health. Weakened by a respiratory illness, he devoted the last year of his life to writing a work of political philosophy, his Political Treatise. Though left unfinished at his death, Spinoza's intention was to show how governments of all types could be improved and to argue for the superiority of democracy over other forms of political organization. Following the lead of Machiavelli and Hobbes, his argument was to be non-utopian, based on a realistic assessment of human nature drawn from the psychological theory set forth in the Ethics. In the part he did finish, Spinoza showed himself to be an astute analyst of diverse constitutional forms and an original thinker among liberal social contract theorists.

Spinoza died peacefully in his rented room in The Hague in 1677. He left no will, but the manuscripts of his unpublished works - the Treatise on the Emendation of the Intellect, the Ethics, the Hebrew Grammar, and the Political Treatise - along with his correspondence were found in in his desk. These were immediately shipped to Amsterdam for publication, and in short order they appeared in print as B.D.S. Opus Posthuma. But even in death Spinoza could not escape controversy; in 1678, these works were banned throughout Holland.

2. Geometric Method and the Ethics

Upon opening Spinoza's masterpiece, the Ethics, one is immediately struck by its form. It is written in the style of a geometrical treatise, much like Euclid's Elements, with each book comprising a set of definitions, axioms, propositions, scholia, and other features that make up the formal apparatus of geometry. One wonders why Spinoza would have employed this mode of presentation. The effort it required must have been enormous, and the result is a work that only the most dedicated of readers can make their way through.

Some of this is explained by the fact that the seventeenth century was a time in which geometry was enjoying a resurgence of interest and was held in extraordinarily high esteem, especially within the intellectual circles in which Spinoza moved. We may add to this the fact that Spinoza, though not a Cartesian, was an avid student of Descartes's works. As is well known, Descartes was the leading advocate of the use of geometric method within philosophy, and his Meditations was written more geometrico, in the geometrical style. In this respect the Ethics can be said to be Cartesian in inspiration.

While this characterization is true, it needs qualification. The Meditations and the Ethics are very different works, not just in substance, but also in style. In order to understand this difference one must take into account the distinction between two types of geometrical method, the analytic and the synthetic. Descartes explains this distinction as follows:


Analysis shows the true way by means of which the thing in question was discovered methodically and as it were a priori, so that if the reader is willing to follow it and give sufficient attention to all points, he will make the thing his own and understand it just as perfectly as if he had discovered it for himself. . . . . Synthesis, by contrast, employs a directly opposite method where the search is, as it were, a posteriori . . . . It demonstrates the conclusion clearly and employs a long series of definitions, postulates, axioms, theorems and problems, so that if anyone denies one of the conclusions it can be shown at once that it is contained in what has gone before, and hence the reader, however argumentative or stubborn he may be, is compelled to give his assent. (CSM II,110-111)

The analytic method is the way of discovery. Its aim is to lead the mind to the apprehension of primary truths that can serve as the foundation of a discipline. The synthetic method is the way of invention. Its aim is to build up from a set of primary truths a system of results, each of which is fully established on the basis of what has come before. As the Meditations is a work whose explicit aim is to establish the foundations of scientific knowledge, it is appropriate that it employs the analytic method. The Ethics, however, has another aim, one for which the synthetic method is appropriate.

As its title indicates, the Ethics is a work of ethical philosophy. Its ultimate aim is to aid us in the attainment of happiness, which is to be found in the intellectual love of God. This love, according to Spinoza, arises out of the knowledge that we gain of the divine essence insofar as we see how the essences of singular things follow of necessity from it. In view of this, it is easy to see why Spinoza favored the synthetic method. Beginning with propositions concerning God, he was able to employ it to show how all other things can be derived from God. In grasping the order of propositions as they are demonstrated in the Ethics, we thus attain a kind of knowledge that approximates the knowledge that underwrites human happiness. We are, as it were, put on the road towards happiness. Of the two methods it is only the synthetic method that is suitable for this purpose.

3. Metaphysics


Although the Ethics is not principally a work of metaphysics, the system it lays out stands as one of the great monuments in the tradition of grand metaphysical speculation. What is perhaps most noteworthy about this system is that it is a species of monism - the doctrine that all of reality is in some significant sense one. In Spinoza's case, this is exemplified by the claim that there is one and only one substance. This substance he identifies as God. While monism has had its defenders in the west, they have been few and far between. Spinoza is arguably the greatest among them.

Descartes and the Pineal Gland




The pineal gland is a tiny organ in the center of the brain that played an important role in Descartes' philosophy. He regarded it as the principal seat of the soul and the place in which all our thoughts are formed.

Today, René Descartes (1596–1650) is mainly known because of his contributions to mathematics and philosophy. But he was highly interested in anatomy and physiology as well. He paid so much attention to these subjects that it has been suggested that “if Descartes were alive today, he would be in charge of the CAT and PET scan machines in a major research hospital” (Watson 2002, p. 15). Descartes discussed the pineal gland both in his first book, the Treatise of man (written before 1637, but only published posthumously, first in an imperfect Latin translation in 1662, and then in the original French in 1664), in a number of letters written in 1640–41, and in his last book, The passions of the soul (1649).

The pineal gland played an important role in Descartes' account because it was involved in sensation, imagination, memory and the causation of bodily movements. Unfortunately, however, some of Descartes' basic anatomical and physiological assumptions were totally mistaken, not only by our standards, but also in light of what was already known in his time

In Descartes' description of the role of the pineal gland, the pattern in which the animal spirits flow from the pineal gland was the crucial notion. He explained perception as follows. The nerves are hollow tubes filled with animal spirits. They also contain certain small fibers or threads which stretch from one end to the other. These fibers connect the sense organs with certain small valves in the walls of the ventricles of the brain. When the sensory organs are stimulated, parts of them are set in motion. These parts then begin to pull on the small fibers in the nerves, with the result that the valves with which these fibers are connected are pulled open, some of the animal spirits in the pressurized ventricles of the brain escape, and (because nature abhors a vacuum) a low-pressure image of the sensory stimulus appears on the surface of the pineal gland. It is this image which then “causes sensory perception” of whiteness, tickling, pain, and so on. “It is not [the figures] imprinted on the external sense organs, or on the internal surface of the brain, which should be taken to be ideas—but only those which are traced in the spirits on the surface of the gland H (where the seat of the imagination and the ‘common’ sense is located). That is to say, it is only the latter figures which should be taken to be the forms or images which the rational soul united to this machine will consider directly when it imagines some object or perceives it by the senses” (AT XI:176, CSM I:106). It is to be noted that the reference to the rational soul is a bit premature at this stage of Descartes' story because he had announced that he would, to begin with, discuss only the functions of bodies without a soul.

Imagination arises in the same way as perception, except that it is not caused by external objects. Continuing the just-quoted passage, Descartes wrote: “And note that I say ‘imagines or perceives by the senses’. For I wish to apply the term ‘idea’ generally to all the impressions which the spirits can receive as they leave gland H. These are to be attributed to the ‘common’ sense when they depend on the presence of objects; but they may also proceed from many other causes (as I shall explain later), and they should then be attributed to the imagination” (AT XI:177, CSM I:106). Descartes' materialistic interpretation of the term ‘idea’ in this context is striking. But this is not the only sense in which he used this term: when he was talking about real men instead of mechanical models of their bodies, he also referred to ‘ideas of the pure mind’ which do not involve the ‘corporeal imagination’.


Descartes' mechanical explanation of memory was as follows. The pores or gaps lying between the tiny fibers of the substance of the brain may become wider as a result of the flow of animal spirits through them. This changes the pattern in which the spirits will later flow through the brain and in this way figures may be “preserved in such a way that the ideas which were previously on the gland can be formed again long afterwards without requiring the presence of the objects to which they correspond. And this is what memory consists in”

Immanuel Kant - The Copernican shift


Immanuel Kant (1724-1804)

Immanuel Kant was born in Königsberg, East Prussia in 1724. He attended the Collegium Fridiricianum at the age of eight, a Latin school that taught primarily classicism. After over eight years of study there, he went into the University Of Königsberg, where he spent his academic career focusing on philosophy, mathematics and physics. The death of his father had a strong effect on Kant, he left the university and earned a living as a private tutor. However, in 1755 he accepted the help of a friend and resumed study, receiving his doctorate in 1756.

He taught at the university and remained there for 15 years, beginning his lectures on the sciences and mathematics, though over time he covered most branches of philosophy. In spite of his growing reputation as an original thinker, he did not gain tenure at the university until 1770, receiving his professorship of logic and metaphysics. He continued writing and lecturing at Königsberg for the next 27 years, drawing many students there due to his rationalist and hence, unorthodox approach to religious texts. This led to political pressure from the government of Prussia, and in 1792, he was barred from teaching or writing on religious subjects by the king, Fredrich William II. Kant dutifully obeyed the injunction until the death of the king five years later, returning to the writing and lecturing of his ideas. The year following his retirement, he published a summary of his views on religion. He died in 1804.

Kant devised a model, an individual epistemology, by examining the basis of human knowledge and its limits. He brought together the ideas of rationalism, influential thinkers such as Leibniz and Wolff, with empiricism as proposed by David Hume. Kant's critical philosophy is presented in the Critique of Pure Reason (1781); the idea of critique is to establish and investigate the legitimate limits of human knowledge. Knowledge of sensible objects must form itself in advance to the structures of the human mind's ability to reason, and therefore all objects conform themselves a priori in such a relation -legitimate knowledge of objects is limited to how they appear for us.

Kant's logic creates a division and complex interplay of judgments- a priori and a posteriori judgments and analytic or synthetic judgments. A judgment is analytic if the subject of its proposition is contained within its predicate, i.e. "Sound theories are theories". To state the reverse would be a logical absurdity. The judgment is considered analytic because the truth of the proposition lies in the validity of the concept itself. All analytic judgments are a priori and thus, as is the case for all a priori judgments, they are independent of experience. However, judgments about empirical knowledge can only be made upon experience, are synthetic, a posteriori, and can be reversed without such a contradiction, i.e. "The theory is sound".

Here unfolds three classes of judgments: a) analytic a priori, b) synthetic a posteriori, and c) synthetic a priori. The particular concern for Kant is the synthetic a priori, for the sciences and mathematics are as such, existing independent of experience and yet as syntheses of previous judgments (knowledge). The question as to the origins of judgments becomes necessary. Metaphysics describes a science concerned with this inquiry, a solution to unsolvable problems set by pure reason itself, namely the concepts of God, freedom and immortality.

Kant developed a system of ethics in Metaphysics of Ethics (1797), in which he places reason as the fundamental authority for morality. Any action born of a mere expediency or servitude to law, politic or custom could be considered as moral, a sense of duty must arise solely as prescribed by reason. Reason dictates two imperatives: the hypothetical and the categorical. In the case of the former, a course of action to accomplish a specific task is presented, and in the latter a course of action that presents itself as appropriate, and necessary. The categorical is the basis for the ethical. This structure defends a fundamental freedom of the individual; that each one be responsible for their own ability, through reason, to obey consciously the laws of the universe.


Kantian philosophy was to have an enormous impact on modern philosophy as well as the fine arts and literature. Hegel was to develop the dialectical method based on elements within the Critique of Pure Reason, which in turn functioned as an underlying structure in Marx's philosophy.
