In one of the unpublished parts of his manuscript titled the Spicilegia, Arthur Schopenhauer presents an uncharacteristically sympathetic reading of an Aristotelian text. The text in question, De anima III. 5, happens to include the only occurrence of arguably the most controversial idea in Aristotle, namely the distinction between active and passive nous. Schopenhauer interprets these two notions as corresponding to his own notions of the ?will? and the ?intellect? or ?subject of knowledge?, respectively. The result is a unique interpretation, (...) according to which Aristotle's active nous is in fact non-intellectual: it is devoid of any interaction with intelligible objects, and hence lacks any intellectual activity. I show that this interpretation, though counterintuitive, is tenable, and that it may contribute to our understanding of Aristotle even if we do not adopt Schopenhauer's metaphysics. (shrink)

In book Zeta of the Metaphysics and elsewhere Aristotle appears to commit himself to the following propositions: (1) No universal can be substance; (2) Form is a universal; and (3) Form is that which is most truly substance. These propositions appear to constitute an inconsistent triad lying at the heart of Aristotle’s ontology. A number of attempts have been made to rescue Aristotle from the charge of inconsistency. Some have claimed that Aristotle did not subscribe to (1), but only to (...) the proposition that nothing predicated universally can be substance. Others hold that, contrary to (2), form is not a universal but peculiar to each individual. Still others argue that the sense of ‘substance’ in which the species form is a substance is not the sense in which no universal is substance. I argue that none of these attempts to rescue Aristotle from the charge of inconsistency is ultimately defensible. (shrink)

In "De anima" 3.5, Aristotle argues for the existence of a second intellect, the so-called "Agent Intellect." The logical structure of his argument turns on a distinction between different types of soul, rather than different faculties within a given soul; and the attributes he assigns to the second species make it clear that his concern here -- as at the climax of his other great works, such as the "Metaphysics," the "Nicomachean" and the "Eudemian Ethics" -- is the difference between (...) the human and the divine. If this is right, we needn't go on a wild goose chase trying to invent a role for the so-called Agent Intellect to play. God moves our intellects as he moves the heavenly spheres, "as a beloved": he constitutes the complete actualization towards which all of our intellectual striving is directed. Aristotle regards such final causation as an efficient cause, but not in a way that would make it part of what we would call the causal processes or mechanisms of human psychology. But, he would insist, it is essential for appreciating who we are and what our place is in the world. (shrink)

Aristotle's discussion of perceiving that we perceive has points of contact with two contemporary debates about consciousness: the first over whether consciousness is an intrinsic feature of mental states or a higher-order thought or perception; the second concerning the qualitative nature of experience. In both cases, Aristotle's views cut down the middle of an apparent dichotomy, in a way that does justice to each set of intuitions, while avoiding their attendant difficulties. With regard to the first issue?the primary focus of (...) this paper?he argues that consciousness is both intrinsic and higher-order, due to its reflexive nature. This, in turn, has consequences for the second issue, where again Aristotle seeks out the middle ground. He is committed against qualia in any strong sense of the term. Yet he also holds that the phenomenal quality of experience is not exhausted by its representational content. (shrink)

Discusses the sense of separability in Aristotle and how they apply to the separability of mind or nous.

When Aristotle speaks of theologikê, he means not the study of a single God, but the study of gods and divine things in general. He never uses the phrase “the unmoved mover” to pick out just one being, and that phrase would not express the essence of the beings it applies to. To see what sort of religious interest there might be in such a being, and how the words “god” and “divine” enter into Aristotle's philosophy, it is best to (...) start with what he says about gods and divine things in moral and political contexts. Guided by his criticisms of Plato on the soul's self-motion, Aristotle sets out, in Physics VIII, to give a revised version of Plato's cosmotheological argument in Laws X. This article focuses on Aristotle's theology and his views about gods, the soul, the cosmos, heavens and heavenly bodies, and the first principle or first cause. (shrink)

This paper focuses on Aristotle’s methodology of science and its application to the study of the human soul. My aim is to contrast two significantly different methodological approaches and to formulate two pairs of premises that Aristotle employs in two clearly differentiated and independent fields of study, namely in his zoological works and in the works of practical philosophy. Acknowledging these principles, as I suggest, may shed a new light on the methodological difficulties that Aristotle indicates in the introductory chapters (...) of his De anima. (shrink)

Gabriel Richardson Lear presents a bold new approach to one of the enduring debates about Aristotle's Nicomachean Ethics: the controversy about whether it coherently argues that the best life for humans is one devoted to a single activity, namely philosophical contemplation. Many scholars oppose this reading because the bulk of the Ethics is devoted to various moral virtues--courage and generosity, for example--that are not in any obvious way either manifestations of philosophical contemplation or subordinated to it. They argue that Aristotle (...) was inconsistent, and that we should not try to read the entire Ethics as an attempt to flesh out the notion that the best life aims at the "monistic good" of contemplation. In defending the unity and coherence of the Ethics, Lear argues that, in Aristotle's view, we may act for the sake of an end not just by instrumentally bringing it about but also by approximating it. She then argues that, for Aristotle, the excellent rational activity of moral virtue is an approximation of theoretical contemplation. Thus, the happiest person chooses moral virtue as an approximation of contemplation in practical life. Richardson Lear bolsters this interpretation by examining three moral virtues--courage, temperance, and greatness of soul--and the way they are fine. Elegantly written and rigorously argued, this is a major contribution to our understanding of a central issue in Aristotle's moral philosophy. (shrink)

Aristotle's claim that natural slaves do not possess autonomous rationality (Pol. 1.5, 1254b20-23) cannot plausibly be interpreted in an unrestricted sense, since this would conflict with what Aristotle knew about non-Greek societies. Aristotle's argument requires only a lack of autonomous practical rationality. An impairment of the capacity for integrated practical deliberation, resulting from an environmentally induced excess or deficiency in thumos (Pol. 7.7, 1327b18-31), would be sufficient to make natural slaves incapable of eudaimonia without being obtrusively implausible relative to what (...) Aristotle is likely to have believed about non-Greeks. Since Aristotle seems to have believed that the existence of people who can be enslaved without injustice is a hypothetical necessity, if those capable oí eudaimonia are to achieve it, the existence of natural slaves has implications for our understanding of Aristotle's natural teleology.

Historians of psychology often treat Aristotle’s De Anima as the first scientific treatment of their subject; and historians of biology do likewise with his zoological treatises. How are the investigations recorded in works such as the Parts of Animals and History of Animals connected to those in the De Anima? More specifically, given Aristotle’s views about man’s special and distinctive cognitive capacities, what does he think about man as an object of a distinctively zoological investigation? In the following pages, this (...) more specific question will be explored, but with an eye to the way in which its answer may change the way we think about the broader question. (shrink)

In this paper I examine Aristotle's account of sexual difference in Generation of Animals, arguing that Aristotle conceives of the production of males as the result of a successful teleological process, while he sees the production of females as due to material forces that defeat the norms of nature. My suggestion is that Aristotle endorses what I call the "degrees of perfection" model. I challenge Devin Henry's attempt to argue that Aristotle explains sex determination exclusively with reference to material necessity (...) (in particular, levels of "vital heat" in the male semen), for Aristotle's notion of "sufficient" or "deficient" vital heat is itself teleological. If, as Aristotle is aware, male and female embryos appear with approximately equal frequency in most species, how, in light of Physics II, can he conceive of the former as in accordance with nature, and the latter as somehow contrary to nature? My proposal is that Aristotle's notion of what happens usually (ως επì τò πoλυ) is bifurcated: the usual need not be more frequent. (shrink)

Desperately difficult texts inevitably elicit desperate hermeneutical measures. Aristotle's De Anima, book three, chapter five, is evidently one such text. At least since the time of Alexander of Aphrodisias, scholars have felt compelled to draw some remarkable conclusions regarding Aristotle's brief remarks in this passage regarding intellect. One such claim is that in chapter five, Aristotle introduces a second intellect, the so-called 'agent intellect', an intellect distinct from the 'passive intellect', the supposed focus of discussion up until this passage.1 This (...) view is a direct descendent of the view of Alexander himself, who identified the agent intellect with the divine intellect.2 Even the staunchest defender of such a view is typically at a loss to give a plausible explanation of why the divine intellect pops into and then out of the picture in the intense and closely argued discussion of the human intellect that goes from chapter four through to the end of chapter seven.3 Revolting against an extravagant postulation of entities, Michael Wedin, for example, has argued with considerable subtlety and ingenuity that there is in fact only one intellect discussed in De Anima.4 This unified intellect is fully capable of being integrated into Aristotle's hylomorphic psychology. In order to make his case, though, Wedin is himself forced (1) to discount the importance of some texts and (2) to interpret others in a way that strains credulity. (shrink)

In De Anima, Aristotle addresses the problem of whether the mind is separable from the body. In book I, he broaches the broader question of whether the affections of the soul, including emotion, desire, and perception, are separable from the body. In book II, Aristotle follows his explication of the general definition of the soul with the remark that “neither the soul nor certain parts of it, if it naturally has parts, are separable from the body. Yet nothing prevents some (...) [parts from being separable], because they are not the actualizations of any body.” By “parts,” Aristotle means separable faculties or powers, including nutrition, perception, mind, and desire. The issue of separability is signalled at the beginning of the treatment of mind in book III. If mind alone turned out to be separable from the body, the study of the soul would not belong exclusively to physics but would spill over into first philosophy. This would imply either that psychology consists of two separate sciences, or else that first philosophy and physics are not mutually exclusive. (shrink)

This essay discusses Aristotle’s theory of the intellect, which is often neglected or misunderstood. It focuses on two doctrines in the theory of intellect: Doctrine One claims that nous is essentially incorporeal and has no bodily organ; and Doctrine Two is the thesis that the intellect in act is identical with its intelligible object. It is argued that D1 is incompatible with the general definition of psuchē, and that the appearance of conflict between D1 and the need for phantasms can (...) be removed by distinguishing between noetic faculty and concrete acts of human thinking. D2 can shed light on the relationship of the nous and empirical consciousness in ordinary thinking, to sharpen the contrast between Aristotle’s view and post-Cartesian philosophy of mind. (shrink)
