مفهوم «کمال» در اندیشه ارسطو به‌طور کلی با دو واژه «انرگیا» و «انتلخیا» بیان شده است که هر دو در انگلیسی به ترجمه شده است. ارسطو در بحث علم‌النفس برای تعریف نفس یکبار نفس را به صورت بدن طبیعی تعریف کرده است و در ادامه آن را به «کمال اول» تعریف کرده است و «کمال نخستین» را در برابر کمال نهایی یا ثانوی قرار داده است. او در تبیین کمال بودن نفس و چرایی «کمال نخستین» برای نفس از آنالوژی تناسب (...) بهره می‌گیرد. پرسش این است چرا در تعریف نفس از صورت به کمال گذر کرده است؟ معنی کمال در تعریف نفس چیست؟ مراد از «اولی» بودن در «کمال» در تعریف نفس چیست؟ چرا ارسطو نفس را کمال نخستین معرفی کرده است؟ مؤلفه‌های کمال نخستین نسبت به کمال نهایی چیست؟ بهره ارسطو از آنالوژی‌ها در تعریف نفس چه بوده است؟ در این نوشتار با بیان آنالوژی‌ها در تعریف نفس در صدد تحلیل این مسئله و پاسخگویی به این پرسش‌ها هستیم.

Aristotle has qualms about the movement of the soul. He contends directly, indeed, that ‘it is impossible that motion should belong to the soul’ (DA 406a2). This is surprising in both large and small ways. Still, when we appreciate the explanatory framework set by his hylomorphic analysis of change, we can see why Aristotle should think of the soul's motion as involving a kind of category mistake-not the putative Rylean mistake, but rather the mistake of treating a change as itself (...) capable of changing.

This paper has three interdependent aims. The first is to make Reichenbach’s views on induction and probabilities clearer, especially as they pertain to his pragmatic justification of induction. The second aim is to show how his view of pragmatic justification arises out of his commitment to extensional empiricism and moots the possibility of a non-pragmatic justification of induction. Finally, and most importantly, a formal decision-theoretic account of Reichenbach’s pragmatic justification is offered in terms both of the minimax principle and the (...) dominance principle.

The current debate over Aristotle's commitment to prime matter is centered on diachronic considerations found in his theory of substantial change. I argue that an appeal to this theory is not required in order to establish his commitment to the existence of prime matter. By drawing on Physics II.1's conception of what it is for an element to have a nature - that is, to have an inner source of movement and rest - I introduce a synchronic justification for the (...) existence of prime matter. By trading on the relationship between the thing that has a source of change and the source it has , I show that something that has a source in itself cannot be identical with its source, and that a type of matter that has no nature of its own (a kind of prime matter) is required to block this identification at the level of the elements.

This paper discusses the metaphysical status of artefacts and their forms in the ancient commentators on Aristotle’s Metaphysics. Specifically, it examines the Peripatetic tradition and Alexander of Aphrodisias to then turn to the commentaries of the late Neoplatonist Asclepius of Tralles, and the Byzantine commentator Michael of Ephesus. It argues that Alexander is the pioneer of the interpretation of artefactual forms as qualities and artefacts as accidental beings. The fortune of this solution goes through Asclepius and Michael to influence Thomas (...) Aquinas. (shrink)

Aristotle’s broad characterization of the soul has been challenged on account of its reliance on the notion of a “potentially alive body”. J. L. Ackrill famously claimed that no body can meet this description without being already actually alive. By a close inspection of both metaphysical and embryological texts, this paper argues that (1) it is embryos (and not fully-formed organic bodies) who provide the right kind of potentially alive subjects and that (2) the schematic character of the soul’s common (...) formula accounts for its seemingly intractable features. It also holds that (3) once the homonymous nature of life is brought into the picture, the κοινότατος λόγος appears unproblematic – at least for some of its most troublesome instances. (shrink)

Este ensayo sostiene que uno de los desafíos más apremiantes que debe enfrentar una psicología de inspiración peripatética es el de conservar la relevancia causal del alma en los tres órdenes del cambio físico (traslación, alteración y crecimiento), sin hacer de ella un “motor” interno que desplace al organismo por hallarse en continuidad con él. En caso de no sortear con éxito este escollo, tal psicología no podrá afirmar que el alma sea un ítem inextenso e impasible, sino (a lo (...) sumo) un cuerpo sutil que desplaza a otro más grosero. Mittelmann propone una lectura conjunta de los tratados de Alejandro y Aristóteles acerca del alma, con el fin de presentar la estrategia de Alejandro como un modo exitoso de hacer frente a esa dificultad patente. Según Mittelmann, Alejandro hallaría en los “estados disposicionales” de Aristóteles el paradigma apropiado para concebir la eficacia causal de las formas. Aquellos podrían oficiar de motores inmóviles en la medida en que reúnen una doble condición, que ni las formas platónicas ni los cuerpos sutiles pueden satisfacer: por una parte, su carácter incorpóreo no los convierte en substancias (separadas); por otra, su carácter inseparable no los convierte en cuerpos que desplacen a otros cuerpos por hallarse en contacto con ellos.

Aristotle claims that just as a builder uses ‘tools’ to build a house, so too the soul ‘use[s] heat and coldness as tools’ to build an animal (Generation of Animals 740b25–34). I consider two questions about this claim: (1) what sorts of things does the soul use, and what is it for things like them to be organized? and (2) what philosophical work does this sort of organization do in Aristotle’s account of animal generation? I argue that the soul needs (...) flexible intermediate agents, that it organizes them in a way that exploits their flexibility, and that this is due to the demands of a complex, multi-stage process directed at a single end.

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)

_ Source: _Volume 63, Issue 1, pp 64 - 86 Five times in the extant corpus, Aristotle refers to a distinction between two ways of being a ‘that for the sake of which’ that he sometimes marks by using genitive and dative pronouns. Commentators almost universally say that this is the distinction between an aim and beneficiary. I propose that Aristotle had a quite different distinction in mind, namely: that which holds between something and the aim or objective it is (...) in the business of producing or achieving, and that which holds between some instrument and the user of that instrument.

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)

Aristotle’s soul is a first principle (an ‘efficient cause’) of every vital change in an animal, in the way that a craft is a cause of its product’s coming-to-be. We argue that the soul’s causal efficacy cannot therefore be reduced to the formal constitution of vital phenomena, or to discrete interventions into independently constituted processes, but involves the exercise of vital powers. This reading does better justice to Aristotle’s conception of craft as a rational productive disposition; and it captures the (...) soul’s continuous causal role as that which brings about all forms of vital change and underwrites their unity.

In the chapter on ‘Plato and Aristotle’ of theLectures on the History of PhilosophyHegel praises Aristotle's work for displaying a principle of ‘pure subjectivity’ in a manner that he considers to be largely absent from the Platoniccorpus:In general, Platonic thinking [das Platonische] represents objectivity, but it lacks a principle of life, a principle of subjectivity; and this principle […], not in the sense of a contingent, merely particular subjectivity, but in the sense of pure subjectivity, is proper to Aristotle. Elsewhere, (...) Hegel refers to Aristotelian conceptions of organic life and of thinking as to the earliest speculative insights of Western philosophy. In § 378 of theEncyclopaedia he calls theDe Anima‘the best or even only work of speculative interest ever written on the philosophy of spirit’. In yet other places, however, Hegel attributes at least ‘intuitive’ forms of speculation to Plato as well.In a preliminary way, a 'speculative relation’ in Hegel's acceptation is instantiated by a subject's theoretical and practical relation to itself — that is, theoretical self-knowing and practical self-will. ‘Speculative’ is any concept which grasps as a unity what other kinds of cognition keep asunder: for example, the subjective and objective dimensions of a phenomenon or state of affairs. But even independently of a detailed analysis of what ‘the speculative’ entails, one is struck by the apparent inconsistency of these claims regarding Plato or Aristotle with Hegel's overall view of the logical necessity of philosophy's historical development. This view is synthetically expressed in the 1820 Introduction to these sameLectures. (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)

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.

In De Anima 2.4, Aristotle claims that nutritive soul encompasses two distinct biological functions: nutrition and reproduction. We challenge a pervasive interpretation which posits ‘nutrients’ as the correlative object of the nutritive capacity. Instead, the shared object of nutrition and reproduction is that which is nourished and reproduced: the ensouled body, qua ensouled. Both functions aim at preserving this object, and thus at preserving the form, life, and being of the individual organism. In each case, we show how Aristotle’s detailed (...) biological analysis supports this ontological argument. (shrink)

In De Anima 1.4, Aristotle asks whether the soul can be moved by its own affections. His conclusion—that to say the soul grows angry is like saying that it weaves and builds—has traditionally been read on the assumption that it is false to credit the soul with weaving and building; I argue that Aristotle’s analysis of psychological motions implies his belief that the soul does in fact weave and build.

I argue that Plato thinks that the soul has location, surface, depth, and extension, and that the Timaeus’ composition of the soul out of eight circles is intended literally. A novel contribution is the development of an account of corporeality that denies the entailment that the soul is corporeal. I conclude by examining Aristotle’s objection to the Timaeus’ psychology and then the intellectual history of this reading of Plato.

This paper is about the history of a question in ancient Greek philosophy and medicine: what holds the parts of a whole together? The idea that there is a single cause responsible for cohesion is usually associated with the Stoics. They refer to it as the synectic cause (αἴτιον συνεκτικόν), a term variously translated as ‘cohesive cause,’ ‘containing cause’ or ‘sustaining cause.’ The Stoics, however, are neither the first nor the only thinkers to raise this question or to propose a (...) single answer. Many earlier thinkers offer their own candidates for what actively binds parts together, with differing implications not only for why we are wholes rather than heaps, but also why our bodies inevitably become diseased and fall apart. This paper assembles, up to the time of the Stoics, one part of the history of such a cause: what is called ‘the synechon’ (τὸ συνέχον) – that which holds things together. Starting with our earliest evidence from Anaximenes (sixth century BCE), the paper looks at different candidates and especially the models and metaphors for thinking about causes of cohesion which were proposed by different philosophers and doctors including Empedocles, early Greek doctors, Diogenes of Apollonia, Plato and Aristotle. My goal is to explore why these candidates and models were proposed and how later philosophical objections to them led to changes in how causes of cohesion were understood. (shrink)

This dissertation is a collection of essays exploring the role of metaphor in Aristotle’s scientific method. Aristotle often appeals to metaphors in his scientific practice; but in the Posterior Analytics, he suggests that their use is inimical to science. Why, then, does he use them in natural science? And what does his use of metaphor in science reveal about the nature of his scientific investigations? I approach these questions by investigating the epistemic status of metaphor in Aristotelian science. In the (...) first essay, I defend an interpretation of metaphor as a type of heuristic reasoning: I claim that Aristotle uses metaphor to express conditions an explanation in natural science must meet if it is to explain regular, ordered change. These conditions specify the kinds of causes—particularly unmoved efficient causes—which the inquirer into nature is seeking. In the second essay, I look to Aristotle’s use of certain endoxa or common beliefs as explanatory principles in science, and show that his use of these principles is similar to his use of metaphor. In the final essay, I present a historical study of the analogy of art and nature, and I suggest that by looking to how the Greeks understood the role of inquiry in the arts, we can shed some light on Aristotle’s views concerning the method of inquiry he thinks the natural scientist should adopt.

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)
