In this paper I consider two related issues raised by Aristotle 's treatment of hearing and sounds. The first concerns the kinds of changes Aristotle takes to occur, in both perceptual medium and sense organs, when a perceiver hears a sounding object. The second issue concerns Aristotle 's views on the nature and location of the proper objects of auditory perception. I argue that Aristotle 's views on these topics are not what they have sometimes been taken to be, and (...) that when rightly understood they compare favourably in many respects with leading contemporary accounts.

At De Anima II 5, 417b17, Aristotle says, ‘The first transition (πρώτη μεταβολή) in that which can perceive is brought about by the parent, and when it is born it already has [the faculty of] sense-perception in the same way as it has knowledge. Actual sense-perception is so spoken of in the same way as contemplation.’ The purpose of this paper is to determine the nature of first transitions.

The notion of a capacity in the sense of a power to bring about or undergo change plays a key role in Aristotle’s theories about the natural world. However, in Metaphysics Θ Aristotle also extends ‘ capacity ’, and the corresponding concept of ‘activity’, to cases where we want to say that something is in capacity, or in activity, such and such but not, or not directly, in virtue of being capable of initiating or undergoing change. This paper seeks to (...) clarify and confirm a certain view of how Aristotle wishes us to see the relationship between the two uses of ‘ capacity ’ and ‘activity’. To that end, I consider also Aristotle’s employment of the terms in the De Anima, which sheds light on the key examples which direct the discussion in Metaph. Θ. (shrink)

In De Anima II 5, 417a21-b16, Aristotle makes a number of distinctions between types of transitions, affections, and alterations. The objective of this paper is to sort out the relationships between these distinctions by means of determining which of the distinguished types of change can be coextensive and which cannot, and which can overlap and which cannot. From the results of this analysis, an interpretation of 417a21-b16 is then constructed that differs from previous interpretations in certain important respects, chief among (...) which is its characterization of transitions from first potentiality to first actuality, e.g., learning, not as `ordinary', but rather as acquisitions of natural dispositions or faculties.

Myles Burnyeat has argued that in De Anima II.5 Aristotle marks out a refined kind of alteration which is to be distinguished from ordinary alteration, change of quality as defined in Physics III.1-3. Aristotle's aim, he says, is to make it clear that perception is an alteration of this refined sort and not an ordinary alteration. Thus, it both supports his own interpretation of Aristotle's view of perception, and refutes the Sorabji interpretation according to which perception is a composite of (...) form and matter where the matter is a material alteration in the body. I argue that Burnyeat's interpretation of II.5 should be rejected for a number of reasons, and offer a new interpretation of the distinctions drawn in the chapter, and the relations between them. I conclude that the chapter provides no evidence against the Sorabji view or for Burnyeat's view. Aristotle's assertion that perception is a refined kind of alteration means that it is the kind of alteration that preserves and is good for the subject of that alteration. There is no inconsistency in the thought that perception is a refined alteration of this sort while it, or its matter, is an ordinary alteration. (shrink)

It is now common to explain some of incidental perception’s features by means of a different capacity, called phantasia. Phantasia, usually translated as ‘imagination,’ is thought to explain how incidental perception can be false and representational by being a constitutive part of perception. Through a close reading of De Anima 3.3, 428b10–29a9, I argue against this and for perception first: phantasia is always a product of perception, from which it initially inherits all its characteristics. No feature of perception is explained (...) directly by phantasia, and phantasia is never a part of perception. Phantasia is not imagination or representation, as many have thought, but perception-like appearance. Aristotle thus recognizes alongside three different types of perception three different types of perception-like appearance. (shrink)

In this paper, I argue that Aristotle was already aware in his earlier texts of the fundamental distinction between motion and activity and of the criterion which structures this contrast. Moreover, I will present textual evidence which suggests that Aristotle’s original concept of ἐνέργεια applies primarily to activities which contain their ends in themselves, and not to motions, which are different from their ends.

Whereas scholars often look to De Anima 2.5 to support one or another understanding of the sense in which perception, for Aristotle, qualifies as an alteration and qualitative assimilation to the sense-object, I ask the more basic question of what the chapter is meant to establish or accomplish with respect to the question whether perception is an alteration. I argue that the chapter does not presuppose or legitimate the view that perception is an alteration where it is thought to, and (...) that it is meant rather to challenge that view, most importantly, by putting its argumentative weight behind a different model of perception, leading to a kind of antinomy. What stands in the way of understanding perception as an alteration (and assimilation to the sense-object), in this chapter, is ultimately the lack of an account of perceiving a quality as having that quality.

Scholarship on Aristotle’s theory of visual perception has traditionally held that Aristotle had a single, static, conception of light and that he believed that illumination occurred prior to and independent of the actions of colours. I contend that this view precludes the medium from becoming actually transparent, thus making vision impossible. I here offer an alternative to the traditional interpretation, using contemporary conceptual tools to make good philosophical sense of Aristotle’s position. I call my view the ‘ecological’ interpretation. It postulates (...) two conceptions of light: non-visible mobile propagated light and visible static illumination produced by the interaction of propagated light with the environment’s coloured textured surfaces. I argue that these contemporary conceptual tools can find a foothold in and consistently enrich Aristotle’s extant position and that, with their aid, we can restore coherence to his theories of light and vision.

This article considers whether and how there can be for Aristotle a genuine science of ‘pure’ psychology, of the soul as such, which amounts to considering whether Aristotle’s model of science in the Posterior Analytics is applicable to the de Anima.

A lot of scholarly attention has been given to Aristotle’s account of how and why animals are capable of moving themselves. But no one has focused on the question, whether self-change is possible in plants on Aristotle’s account. I first give some context and explain why this topic is worth exploring. I then turn to Aristotle’s conditions for self-change given in Physics VIII.4, where he argues that the natural motion of the elements does not count as self-motion. I apply those (...) conditions to natural change in plants. Then I explore the reasons for and consequences of Aristotle’s argument that plants are incapable of sensation. I argue that for Aristotle plants cannot possess the directing faculties for self-change, namely, desire and phantasia. My goal is to show why growth, metabolism, and reproduction in plants would not count as self-change for Aristotle, despite many of these natural changes appearing as autonomous as the analogous changes in animals. This sheds light on how, for Aristotle, self-change differs from natural change. (shrink)

The present dissertation concerns cognitive psychology—theories about the nature and mechanism of perception and thought—during the High Middle Ages (1250–1350). Many of the issues at the heart of philosophy of mind today—intentionality, mental representation, the active/passive nature of perception—were also the subject of intense investigation during this period. I provide an analysis of these debates with a special focus on Durand of St.-Pourçain, a contemporary of John Duns Scotus and William of Ockham. Durand was widely recognized as a leading philosopher (...) until the advent of the early modern period, yet his views have been largely neglected in the last century. The aim of my dissertation, then, is to provide a new understanding of Durand’s cognitive psychology and to establish a better picture of developments in cognitive psychology during the period. -/- Most philosophers in the High Middle Ages held, in one form or another, the thesis that most forms of cognition (thought, perception) involve the reception of the form of the object into the mind. Such forms in the mind explain what a given episode of cognition is about, its content. According to what has been called the conformality theory of content, the content of our mental states is fixed by this form in the mind. Durand rejects this thesis, and one of the primary theses that I pursue is that Durand replaces the conformality theory of content with a causal theory of content, according to which the content of our mental states is fixed by its cause. When I think about Felix and not Graycat, this is to be explained not by the fact that I have in my mind the form of Felix and not Graycat, but rather by the fact that Felix and not Graycat caused my thought. -/- This is both a controversial interpretation and, indeed, a controversial theory. It is a controversial interpretation because Durand seems to reject the thesis that objects are the causes of our mental states. In the first half of the present dissertation, I argue that Durand does not reject this thesis but he rejects another nearby thesis: that objects as causes give to us ‘forms’. On Durand’s view, an object causes a mental state even though it does not give to us a new ‘form’. In the second half of the dissertation I defend Durand’s causal theory of content against salient objections to it. (shrink)

It is commonly assumed that Aristotle's ethical theory shares deep structural similarities with neo-Aristotelian virtue ethics. I argue that this assumption is a mistake, and that Aristotle's ethical theory is both importantly distinct from the theories his work has inspired, and independently compelling. I take neo-Aristotelian virtue ethics to be characterized by two central commitments: (i) virtues of character are defined as traits that reliably promote an agent's own flourishing, and (ii) virtuous actions are defined as the sorts of actions (...) a virtuous agent reliably performs under the relevant circumstances. I argue that neither of these commitments are features of Aristotle's own view, and I sketch an alternative explanation for the relationship between virtue and happiness in the Nicomachean Ethics. Although, on the interpretation I defend, we do not find in Aristotle a distinctive normative theory alongside deontology and consequentialism, what we do find is a way of thinking about how prudential and moral reasons can come to be aligned through a certain conception of practical agency.

I argue that a common interpretation of DA 3.4, which sees Aristotle as there rejecting Anaxagoras’s account of mind, is mistaken. Instead, I claim that, in providing his solution to the main puzzles of this chapter, Aristotle takes special care to preserve the essential features that he thinks Anaxagoras ascribes to mind, namely, its ability to know all things, its being unmixed, and its inability to be affected by mixed objects.

Aristotle's theory of perception is complicated by the fact that he recognizes three kinds of perceptible object: special, common, and incidental, all of which have different levels of reliability. Focusing on De Anima 3.3, 428b17–25, this paper discusses why these three sorts of perception are true and false. It argues that perceptions of special objects can be false because of the blind-spot phenomenon and that common objects are typically perceived as predicated of an incidental object. This helps explain why perceptions (...) of common objects are the most error prone. The paper ends with a suggestion about the importance of predicational perception for Aristotle's epistemology.

In Proclus’Platonic Theology(V 17, 62. 22–63. 2) one can detect a clear recollection of the well-known and much discussed passage 1048b18–35 fromMetaphysicsIX 6. This passage is transmitted in only one branch of the manuscript tradition and some scholars maintain that it is not by Aristotle or that it does not belong to hisMetaphysics. On the other hand, Proclus’ testimony, supported by other passages by Neo-Platonic authors, provides an argument for the original location of the discussed section in Aristotle’sMetaphysics.

Averroes held the controversial thesis that there is only one separate material or possible intellect for all humans. This paper analyzes a passage from his Long Commentary on the De Anima which has been thought to constitute a primary philosophical argument for the view. It is called the Determinate Particular Argument, because it contends that the material intellect cannot be a determinate particular if it is to be the ontological receptacle of universal intelligible forms. After defending one crucial premise, it (...) will be shown how the key term “determinate particular” must be qualified to avoid an inconsistency with Averroes’s metaphysics and his position on the species membership of separate substances. Given this qualification in the face of competing views, the paper concludes that the Determinate Particular Argument should not be taken as a sufficient and independent argument for Averroes’s full thesis on the intellect.

It is well known that when it comes to perception in the De anima, Aristotle uses affection-related vocabulary with extreme caution. This has given rise to a debate between interpreters who hold that in Aristotle’s account, the act of sense-perception nevertheless involves the physiological alteration of the sense organ (Richard Sorabji), and those think, with Myles Burnyeat, that for Aristotle, perception does not involve any material process, so that an Aristotelian physics of sense-perception is a “physics of forms alone”. The (...) present article suggests that the dematerialisation of Aristotle’s theory of perception, which has a long story from Alexander of Aphrodisias to Brentano, may be in fact traced back to Theophrastus’ exegesis of Aristotle’s relevant passages in the De anima in his Physics, as we can reconstruct it on the basis of Priscian’s Metaphrasis in Theophrastum and Simplicius’ commentary of Aristotle’s De Anima. The reconstruction also provides a scholastic-theoretical frame to Theophrastus’ critical exposition of ancient theories about sense perception in his De sensibus, whether or not the discussion originally belonged to Theophrastus’ Physics.

The soul is an explanatory principle of Aristotle’s natural science, accounting both for the fact that living things are alive as well as for the diverse natural attributes that belong to them by virtue of being alive. I argue that the explanatory role of the soul in Aristotle’s natural science must be understood in light of his view, stated in a controversial passage from Parts of Animals (645b14–20), that the soul of a living thing is a “complex activity” of its (...) organic body. This paper explores the role of this “complex activity” model of soul in Aristotle’s study of soul in De Anima. I argue, first, that the model has its origins in De Anima II.4, where Aristotle argues that living things do all they do by nature for the sake of a single, teleologically primary end. I argue further that Aristotle uses this model to account for the psychological attributes naturally present in living things, including their capacities for vital activities like nutrition, reproduction, and perception, and that this is the task to which Aristotle devotes the obscure final chapters of De Anima III.

Aristotle’s most fundamental distinction between changes and other activities is not that ofMetaphysicsΘ.6, between end-exclusive and end-inclusive activities, but one implicit inPhysics3.1’s definition of change, between the activity of something incomplete and the activity of something complete. Notably, only the latter distinction can account for Aristotle’s view, inPhysics3.3, that ‘agency’—effecting change in something, e.g. teaching—does not qualify strictly as a change. This distinction informsDe Anima2.5 and imparts unity to Aristotle’s extended treatment of change inPhysics3.1-3.

Su respuesta fue muy influyente, especialmente después de la Quaestio III 3 que había sido traducida al latín por Gerardo de Cremona basada en una versión árabe. De hecho, aún es muy influyente, pues en general es tomada en cuenta por los comentadores modernos del De anima.

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)

In an attempt to reject Cartesian Dualism, some philosophers and scientists of the late twentieth century proposed a return to the ancient position that Descartes had opposed, i.e., Aristotle’s psychological hylomorphism, which applied to living beings the ontological thesis, according to which every substance is a compound of matter (hyle) and form (morphe). In this perspective, the soul is actual possession of the body’s capacity to perform a series of life functions. Therefore, according to Aristotle, soul and body are reciprocally (...) interdependent aspects of the living being, so that we must consider the former as an enmattered form, and the latter as an enformed or ensouled matter. This means that, for Aristotle, all the functions of the soul, even the highest ones like thought, are essentially connected with the body, since they ultimately require sensations. This paper illustrates and supports this doctrine in detail, especially in relation to the cognitive processes of the human mind. (shrink)

This paper deals with a seeming contradiction that may seriously impair Aristotle’s definition of the soul in his De Anima. While this definiens has been widely regarded as providing a non-dualistic account of life-functions, grounded in a hylomorphic approach to living beings, Aristotle sticks to an instrumental language vis-à-vis the body, which he consistently refers to as a tool of the soul. It is argued that this philosophical way of talking should be taken at face value, without dismiss- ing it (...) as a stylistic feature or a theoretical hangover from Aristotle’s Platonic days. By paying close attention to the Peripatetic and Neoplatonic reception of the “soul – boatman analogy”, the paper concludes that organic bodies may be considered as instrumental in nature, without this entailing commitment to further individual souls conceived as “users”.

Aristotle’s Naïve Somatism is a re-interpretation of Aristotle’s cognitive psychology in light of certain presuppositions he holds about the living animal body. The living animal body is presumed to be sensitive, and Aristotle grounds his account of cognition in a rudimentary proprioceptive awareness one has of her body. With that presupposed metaphysics under our belts, we are in a position to see that Aristotle in de Anima (cognition chapters at least) has a di erent explanatory aim in view than that (...) which the literature generally imputes to him. He is not explicating what we would call the “mental”—the private, inner realm which some take to be of a di erent kind than the physical—as most take him to be. His explanandum is content acquisition; the explanans is showing how the body becomes like various aspects of objects. Although he famously describes the mind (nous) as unmixed with the body, he is guided by functional constrains—nous cannot be limited or qualified if it is to potentially think all things. Thus, his inquiry into cognition is philosophically limited from a contemporary perspective. Aristotle is not doing philosophy of mind, for he doesn’t seem to find the “mental” philosophically perplexing. (shrink)
