This debate, I shall argue, has everything to do with Aristotle. Aristotle raises the charge of epiphenomenalism himself against a theory that seems to have close affinities to his own, and he offers what has the makings of an emergentist response. This leads to controversy within his own school. We find opponents ranged on both sides, starting with his own pupils, several of whom are stout defenders of epiphenomenalism, and culminating in the developed emergentism of later commentators. Aristotle’s theory and the debate that ensued are thus quite relevant to contemporary discussions. But first we need to get clear on terms.

Le présent article offre une nouvelle interprétation du concept aristotélicien d' « imagination » ou phantasia par les moyens d'une lecture attentive du Traité de l'âme, III, 3, tout particulièrement de son début. Aristote soutient que ses prédécesseurs ne peuvent expliquer comment l'erreur se produit. Mais c'est également une difficulté pour sa propre explication des formes de base de la perception et de la pensée, et Aristote introduit la phantasia précisément pour répondre à cette question. Il soutient qu'elle ne peut être réduite aux autres états mentaux et offre donc une nouvelle explication causale du contenu, laquelle explique comment un état mental peut être aussi bien vrai que faux. The present article offers a new interpretation of Aristotle's concept of « imagination » or phantasia through a close reading of On the Soul, 3. 3, with special attention to the chapter's opening. Aristotle argues that his predecessors cannot explain how error can ever occur. But it is equally a difficulty for his own account of the most basic types of perception and thought, and Aristotle introduces phantasia precisely to answer this problem. He argues that it cannot be reduced to other mental states and then offers a new causal account of content which explains how a mental state can be either true or false.

Aristotle not only formulates the problem of intentionality explicitly, he makes a solution to it a requirement for any adequate theory of mind. His own solution, however, is not to be found in his theory of sensation, as Brentano and others have thought. In fact, it is precisely because Aristotle regards this theory as inadequate that he goes on to argue for a distinct new ability he calls "phantasia." The theory of content he develops on this basis (unlike Brentano's) is profoundly naturalistic: it is a representational theory, formulated in terms of the causal powers and physical magnitudes of the body.

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
