I offer a novel interpretation of Aristotle's psychology and notion of rationality, which draws the line between animal and specifically human cognition. Aristotle distinguishes belief (doxa), a form of rational cognition, from imagining (phantasia), which is shared with non-rational animals. We are, he says, “immediately affected” by beliefs, but respond to imagining “as if we were looking at a picture.” Aristotle's argument has been misunderstood; my interpretation explains and motivates it. Rationality includes a filter that interrupts the pathways between cognition (...) and behavior. This prevents the subject from responding to certain representations. Stress and damage compromise the filter, making the subject respond indiscriminately, as non-rational animals do. Beliefs are representations that have made it past the filter, which is why they can “affect [us] immediately.” Aristotle's claims express ceteris paribus generalizations, subject to exceptions. No list of provisos could turn them into non-vacuous universal claims, but this does not rob them of their explanatory power. Aristotle's cognitive science resolves a tension we grapple with today: it accounts for the specialness of human action and thinking within a strictly naturalistic framework. The theory is striking in its insight and explanatory power, instructive in its methodological shortcomings. (shrink)

Aristotle’s cryptic De Anima III 5 has precipitated an enormous volume of commentary, especially about the identity of what has come to be known as active intellect and how it relates to potential intellect. Some take active intellect to be the prime mover of Metaphysics Λ, others a hypostatic or cosmic principle (for example, an ideal Intellect, intellect associated with the tenth celestial sphere, etc.), and others a faculty, potentiality, or power of the human soul that is distinct in function, (...) office, or operation from potential intellect. But a very different, ontologically lightweight way of characterizing active and potential intellect can be reconstructed from fragments of a work by the only interpreter personally acquainted with Aristotle, his junior colleague, Theophrastus of Eresus. This reconstruction suggests various philosophically attractive solutions to notorious problems raised by Aristotle’s text. (shrink)

Ethics for Rational Animals brings to light a novel account of akrasia, practical wisdom, and character virtue through an original and comprehensive study of the moral psychology at the basis of Aristotle's ethics. It argues that practical wisdom is a persuasive rational excellence, that virtue is a listening excellence, and that the ignorance involved in akrasia is in fact a failure of persuasion. Aristotle's moral psychology emerges from this reconstruction as a qualified intellectualism. The view is intellectualistic because it describes (...) practical wisdom as the sort of knowledge that can govern desire and action and akrasia as involving a form of ignorance. However, Aristotle's intellectualism is qualified because practical wisdom goes beyond grasping the truth about the human good, for it must also be able to convey the truth persuasively to non-rational cognition and desires.

Aristotle thinks that happiness is an activity---it consists in doing something---rather than a feeling. It is the best activity of which humans are capable and is spread out over the course of a life. But what kind of activity is it? Some of his remarks indicate that it is a single best kind of activity, intellectual contemplation. Other evidence suggests that it is an overarching activity that has various virtuous activities, ethical and intellectual, as parts. At stake are questions about (...) how we should live and the correct balance of theoretical and practical activity. Numerous interpreters have sharply disagreed about Aristotle's answers to such questions. This book offers a fundamentally new approach to determining what kind of activity Aristotle thinks happiness is, one that challenges widespread assumptions that have until now prevented a dialectically satisfactory interpretation. This approach displays the boldness and systematicity of Aristotle's practical philosophy. (shrink)

I argue that the science of the soul only covers sublunary living things. Aristotle cannot properly ascribe ψυχή to unmoved movers since they do not have any capacities that are distinct from their activities or any matter to be structured. Heavenly bodies do not have souls in the way that mortal living things do, because their matter is not subject to alteration or generation. These beings do not fit into the hierarchy of soul powers that Aristotle relies on to provide (...) unity to ψυχή. Their living consists in their activities, not in having a capacity for activity.

I examine the passages where Aristotle maintains that intellectual activity employs φαντάσματα (images) and argue that he requires awareness of the relevant images. This, together with Aristotle’s claims about the universality of understanding, gives us reason to reject the interpretation of Michael Wedin and Victor Caston, on which φαντάσματα serve as the material basis for thinking. I develop a new interpretation by unpacking the comparison Aristotle makes to the role of diagrams in doing geometry. In theoretical understanding of mathematical and (...) natural beings, we usually need to employ appropriate φαντάσματα in order to grasp explanatory connections. Aristotle does not, however, commit himself to thinking that images are required for exercising all theoretical understanding. Understanding immaterial things, in particular, may not involve employing phantasmata. Thus the connection that Aristotle makes between images and understanding does not rule out the possibility that human intellectual activity could occur apart from the body. (shrink)

This paper examines Pomponazzi's arguments against Averroes in his De Immortalitate Animae, focusing on the question whether thought is possible without a body. The first part of the paper will sketch the history of the problem, namely the interpretation of Aristotle's remarks about the intellect in De Anima 3.4-5, touching on Alexander, Themistius, and Averroes. The second part will focus on Pomponazzi's response to Averroes, including his use of arguments by Aquinas. It will conclude by suggesting that Pomponazzi's discussion stands (...) as the first properly modern account of Aristotle's psychology. (shrink)

Aristotle’s theory of human happiness in the Nicomachean Ethics explicitly depends on the claim that contemplation (theôria) is peculiar to human beings, whether it is our function or only part of it. But there is a notorious problem: Aristotle says that divine beings also contemplate. Various solutions have been proposed, but each has difficulties. Drawing on an analysis of what divine contemplation involves according to Aristotle, I identify an assumption common to all of these proposals and argue for rejecting it. (...) This allows a straightforward solution to the problem and there is evidence that Aristotle would have adopted it. (shrink)

Highlighting the relations between De Anima II.5 and De Anima III.4, this paper argues that Aristotle held a surprisingly dynamic view of the intellect. According to this view, the intellect is in...

El presente artículo se enfrenta al problema clásico sobre cómo interpretar lo que Aristóteles, en de An. III, 5, denomina “el intelecto que produce todas las cosas”, llamado comúnmente intelecto agente. Históricamente, se han presentado dos lecturas: una, que se remonta a Alejandro de Afrodisia, que lo asocia con el motor inmóvil y con la divinidad y otra, asociada a Teofrasto pero que tiene en Filópono y St. Tomás de Aquino a sus principales representantes, que lo considera una facultad puramente (...) humana. Esta última interpretación ha sido históricamente la más sostenida; sin embargo, en tiempos recientes ha habido un resurgimiento de interpretaciones del intelecto agente como “divino”. Lo que queremos mostrar en este texto es que este resurgimiento se debe, más que a una reinterpretación del intelecto agente, a una comprensión diferente de la divinidad en la filosofía aristotélica, con características inmanentes y más próximas al intelecto humano.

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)

The debate between ‘inclusive’ and ‘dominant’ interpretations of Aristotle's concept of happiness (eudaimonia) has become one of the thorniest problems of Aristotle interpretation. In this paper, I attempt to solve this problem by presenting a multi-step argument for an ‘all-inclusive’ thesis, i.e., the Aristotelian philosopher or contemplator, in the strict sense, is someone who already possesses all the intellectual virtues (except technē), all the moral virtues (by way of the possession of phronēsis), and considerable other goods. If this thesis is (...) correct, the inclusive and dominant interpretations will converge, for the philosopher turns out to be the happiest human being both in the inclusive and dominant senses.
