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)

In one of the unpublished parts of his manuscript titled the Spicilegia, Arthur Schopenhauer presents an uncharacteristically sympathetic reading of an Aristotelian text.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 many of his writings, Castoriadis argues that ‘the discovery of the imagination’ occurs in the works of Aristotle, Kant, Fichte, Freud, Heidegger and Merleau-Ponty. Although he has systematically encountered and interrogated the works of Aristotle, Kant, Freud, and Merleau-Ponty, the work of Fichte remains an enigmatic absence within the orbit of Castoriadis' work. This study is an attempt to address this enigma through a close reading of Fichte’s The Science of Knowledge.

Akrasia is a philosophical concept meaning the possibility to perform actions against one's best judgement. This contribution aims to clarify this phenomenon in terms of a social construction, stating it as a narrative configuration generated by an observer. The latter finds himself engaged in justifying a “problematic” line of action with regard to specific cultural beliefs referring to the self, the others and the behaviour. This paper intends to make explicit the assumptions underlying the traditional definitions of akrasia when, paradoxically, (...) an agent performs an action not in accordance with his/her best judgement. In the transition from modern to post-modern psychology, we here propose an interpretation of the phenomenon in psychological terms, envisaging akrasia as a narrative form functional to the identity processes and to the social dynamics of the structures of contemporary societies. Implications in the psychological practice will be taken into account. (shrink)

Modern logicians have complained that Aristotelian logic lacks a distinction between predication and assertion, and that predication, according to the Aristotelians, implies assertion. The present paper addresses the question of whether this criticism can be levelled against Aristotle’s logic. Based on a careful study of the De interpretatione, the paper shows that even if Aristotle defines what he calls simple assertion in terms of predication, he does not confound predication and assertion. That is because, first, he does not understand compound (...) assertion in terms of predication, and secondly, he acknowledges non-assertive predicative thoughts that are truth-evaluable. Therefore, the implications of Aristotle’s ‘predication theory of assertion’ are not as devastating as the critics believe. (shrink)

Duas das principais controvérsias que têm ocupado aqueles que se dedicam à teoria aris- totélica do movimento animal são a controvérsia acerca da forma da cognição através da qual um animal irracional apreende um objeto como um objeto de desejo e a controvérsia acerca da função desempenhada pela cognição na explicação aristotélica dos movimentos voluntários de locomoção animal. Neste artigo, eu apresento uma teoria acerca das formas como o desejo e a cognição se articulam na teoria aristotélica segundo a qual (...) um animal irracional apreende um objeto como um objeto de desejo através da percepção incidental deste objeto e, ao contrário do que a maioria parece acreditar, esta percepção não tem sempre a mesma função na produção destes movimentos. Se o que for dito aqui estiver correto, em alguns casos esta percepção é responsável tanto pela geração do desejo quan- to pela sua orientação, mas em outros ela é responsável apenas pela sua orientação.

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)

The aim of this article is to strengthen links between cognitive brain research and formal logic. The work covers three fundamental sorts of logical inferences: reasoning in the propositional calculus, i.e. inferences with the conditional “if...then”, reasoning in the predicate calculus, i.e. inferences based on quantifiers such as “all”, “some”, “none”, and reasoning with n-place relations. Studies with brain-damaged patients and neuroimaging experiments indicate that such logical inferences are implemented in overlapping but different bilateral cortical networks, including parts of the (...) fronto-temporal cortex, the posterior parietal cortex, and the visual cortices. I argue that these findings show that we do not use a single deterministic strategy for solving logical reasoning problems. This account resolves many disputes about how humans reason logically and why we sometimes deviate from the norms of formal logic. (shrink)

Although it is common for interpreters of Aristotle's De Anima to treat the soul as a specially related set of powers of capacities, I argue against this view on the grounds that the plausible options for reconciling the claim that the soul is a set of powers with Aristotle's repeated claim that the soul is an actuality cannot be unsuccessful. Moreover, I argue that there are good reasons to be wary of attributing to Aristotle the view that the soul is (...) a set of powers because this claim conflicts with several of his metaphysical commitments, most importantly his claims about form and substance. I argue that although there are passages in the De Anima in which Aristotle discusses the soul in terms of its powers or capacities, these discussions do not establish that the soul is a set of capacities.

Aristotle's notion of experience plays an important role in his epistemology as the link between perception and memory on the one side, and higher cognitive capacities on the other side. However, Aristotle does not say much about it, and what he does say seems inconsistent. Notably, some passages suggest that it is a non-rational capacity, others that it is a rational capacity and that it provides the principles of science. This paper presents a unitary account of experience. It explains how (...) experience grows from perception and memory into a rational capacity, and in what way it provides the principles. (shrink)

In this paper we argue that Aristotle operates with a particular theoretical model in his explanation of animal locomotion, what we call the ‘centralized incoming and outgoing motions’ model. We show how the model accommodates more complex cases of animal motion and how it allows Aristotle to preserve the intuition that animals are self-movers, without jeopardizing his arguments for the eternity of motion and the necessary existence of one eternal unmoved mover in Physics VIII. The CIOM model helps to elucidate (...) Aristotle’s two central yet problematic claims, namely that the soul is the efficient cause of animal motion and that it is the internal supporting-point necessary for animal motion. Moreover, the CIOM model helps us to explain the difference between voluntary, involuntary and non-voluntary motions, and to square Aristotle’s cardiocentrism with his hylomorphism, but also, more generally, it provides an interesting way of thinking about the place of intentionality in the causal structure of the world.

I argue that a study of the Nicomachean Ethics and of the Parva Naturalia shows that Aristotle had a notion of attention. This notion captures the common aspects of apparently different phenomena like perceiving something vividly, being distracted by a loud sound or by a musical piece, focusing on a geometrical problem. For Aristotle, these phenomena involve a specific selectivity that is the outcome of the competition between different cognitive stimuli. This selectivity is attention. I argue that Aristotle studied the (...) common aspects of the physiological processes at the basis of attention and its connection with pleasure. His notion can explain perceptual attention and intellectual attention as voluntary or involuntary phenomena. In addition, it sheds light on how attention and enjoyment can enhance our cognitive activities. (shrink)

The possibility of a harmony between the psychological doctrine of Aristotle and that of Plato marks a significant issue within the context of the debate surrounding Aristotle’s putative opposition to or harmony with Plato’s philosophy. The standard interpretation of Aristotle’s conception of the soul being purely hylomorphic leaves no room for harmonisation with Plato, nor does a functionalist interpretation that reduces Aristotle’s psychological doctrine to physicalist terms. However, these interpretations have serious drawbacks, both in terms of ad-hoc explanations formulated in (...) the developmentalist mode, and the misconstruing of some of the fundamental features of Aristotle’s psychological doctrine. A dualist interpretation that accepts Aristotle’s doctrine of some part of the soul being properly incorporeal, separable and immortal overcomes these drawbacks and, significantly, opens the door for Platonic harmonisation. Furthermore, it can be shown that the kind of immortality in question is also in line with the Platonic stance, due to a deep similarity between the conceptions of metaphysical and moral personhood held by Plato and his student. However, this Aristotelian dualism is not Platonic dualism simpliciter. Rather, it is best understood in terms of the division of labour between Aristotle and Plato suggested by the Neoplatonic commentators generally, and Simplicius in particular. I argue that though questions surrounding these issues and particularly the issue of reincarnation remain, an account of Aristotle’s psychological doctrine as dualist and in harmony with Plato’s view of the soul can be shown to be stronger than both standard hylomorphic and functionalist accounts, both exegetically and philosophically.

I reconstruct Aristotle’s reasons for thinking that the intellect cannot have a bodily organ. I present Aristotle’s account of the aboutness or intentionality of cognitive states, both perceptual and intellectual. On my interpretation, Aristotle’s account is based around the notion of cognitive powers taking on forms in a special preservative way. Based on this account, Aristotle argues that no physical structure could enable a bodily part or combination of bodily parts to produce or determine the full range of forms that (...) the human intellect can understand. For Aristotle, cognitive powers with bodily organs are always spatiotemporally limited, but the understanding is not. Aristotle claims that our understanding applies to all instances of the thing understood wherever and whenever they exist. On Aristotle’s own account the intellect in its nature is only “potential,” it does not actually possess any form. Thus nothing prevents it from possessing all forms. (shrink)

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)

I lay out and examine two sharply conflicting interpretations of Aristotle's claims about nous in the De Anima (DA). On the human separability approach, Aristotle is taken to have identified reasons for thinking that the intellect can, in some way, exist on its own. On the naturalist approach, the soul, including intellectual soul, is inseparable from the body of which it is the form. I discuss how proponents of each approach deal with the key texts from the DA, focusing on (...) four of the most important and interesting topics in this area. Two of these topics concern the activity of understanding (noêsis): first, what does Aristotle mean when he claims that the intellect cannot have a bodily organ and, secondly, what role does Aristotle think phantasmata (“images” or “representations”) play in understanding something? Two of the topics concern DA 3.5, one of the most difficult passages in Aristotle's corpus: first, what is the nature and role of the productive intellect (nous poiêtikos) introduced there and, secondly, what are this chapter's implications for the question of whether the intellect or intellectual soul can exist apart from the body? I conclude by identifying areas where further research is necessary. (shrink)

In De Anima III.3 Aristotle presents his official discussion of phantasia (“imagination” in most translations). At the very outset of the discussion Aristotle offers as an endoxon that “phantasia is that in virtue of which we say that a phantasma occurs to us” (428a1-2). Now a natural reading of this claim, taken up by many commentators, can pose a problem for Aristotle’s overall account of perception. Here I argue that, although it would be silly to deny that Aristotle considers phantasia (...) to be that in virtue of which a phantasma occurs to someone, it is not silly to deny that phantasmata are present in every case in which phantasia is operative. This suggestion bolsters the idea that, according to Aristotle’s account of veridical perception, we can understand the world as making itself perceptually manifest to the perceiver. (shrink)

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)
