Aristotle: Soul

This is the latest draft of our translation of our reconstruction of Aristotle's lost work, the Protrepticus (Exhortation to Philosophy). The front matter indicates how to cite the work and the translation. We are currently in the process of preparing a critical Greek edition and commentary.

Aristotle discusses the soul in itself in metaphysics, and as its relation to the body in physics. This issue originates in the division of sciences in Aristotle's works. The same trend continues in the works of the philosophers following him. Although Farabi presented a new classification of sciences, he maintained the main form of Aristotle's divisions and posed the related problems like him. Based on his fundamental theories, including the principiality of existence, gradation of being, and the trans-substantial motion, Mulla (...) Sadra considers the soul to be corporeally originated and spiritually subsistent, criticizes early philosophers' ideas concerning the soul and its place, and offers a new interpretation of the soul. He could have removed the distinction between the stations of the essence of the soul and its relation and considered it to be a level of the body and a mode of existence at the beginning of its creation. Accordingly, he transfers the issues related to the soul from physics to metaphysics and contributes to the independence of the latter. Mulla Sadra believes that it is the responsibility of philosophers to discuss the soul, and, in addition to emphasizing the importance of this discussion, he maintains that the issue of providence is the link between the issues of the soul and the third journey. His definition of the soul and perception of philosophy and anthropology made it possible for Mulla Sadra to create some changes in the place of the soul and discuss it in metaphysics, which is something that the philosophers before him were not able to do. This paper deals with the effects and consequences of this issue. (shrink)

Aristotle's Physics 218b21-219a has been interpreted as proof that the concept of time is determined by the perceptive (or perceptual) conditions of the mind (psyche). In this paper I will criticize such an interpretation in order to argue that the mind's conditions for the perception and experience of time are just a starting point for the investigation: what is prior and nearer to sense, and better known to man (Anal. Post. I, 2). The arrival point of Aristotle's investigation about the (...) concept of time, it's first nature or what is prior in the order of being, is the necessary connection between the existence of time and change. His description of the sleeping Sardinians allows him to determine the elements involved in the perception of time and, consequently, to determine the elements that make up the existence of time.

Although scholars acknowledged that Avicenna’s science of the soul stands at the crossroads between natural philosophy and metaphysics, thus combining an overall physical investigation of all sublunary souls with a trans-physical (or proto-metaphysical) inquiry into the human rational soul, this paper aims to show a further disciplinary entanglement within Avicenna’s science of the soul, which features in the aforementioned physical investigation and helps to frame it, that is, the interaction between natural philosophy and medicine. Despite the strict division between these (...) two disciplines in Avicenna’s system of science, medicine seems to decisively contribute to accounting for the bodily functions of living beings. For this reason, Avicenna refers to medicine several times in his exposition on the soul. This paper approaches the disciplinary entanglement between natural philosophy and medicine in psychology by focusing on the medical concept of pneuma (rūḥ), which prominently features in the exposition of three main issues in psychology, i.e., body ensoulment, powers differentiation, and emotions.

Does Aristotle offer a definition of the soul? In fact, he rejects the possibility of defining the soul univocally. Because “life” is a homonymous concept, so too is “soul”. Given the specific causal role that Aristotle envisages for form and essence, the soul requires multiple different definitions to capture how it functions as a cause in each form of life. Aristotle suggests demonstrations can be given which express these causal definitions; I reconstruct these demonstrations.

In this essay I examine some instances of the relations between body and soul and between health and salvation in the development of the ‘medicine of the soul’, that is ‘spiritual medicine’ (12th–15th centuries). In particular, I examine texts by theologians and men of Church – Hugo de Fouilloy, Alanus de Insulis, Humbert de Romans, Nicola of Occam, Giovanni da S. Gimignano, Bartolomeo da Ferrara and Jean Gerson – in which aspects of secular medicine are used for ethical and spiritual (...) aims. I also touch upon some physicians – Gilles de Corbeil, Arnaldo da Villanova, Galvano da Levanto, Michele Savonarola – who are, in their medical writings, very attentive to the health of the soul and its salvation.

Dans ses écrits biologiques et éthiques, Aristote affirme explicitement que les animaux non humains sont capables d’action volontaire. Mais d’autres aspects de son traitement du volontaire dans ces mêmes écrits semblent contredire cette affirmation et impliquer que le volontaire nécessite une faculté rationnelle spécifiquement humaine. Les lecteurs d’Aristote ont proposé diverses solutions à ce problème. Un premier groupe dit qu’Aristote définit le volontaire uniquement en termes de capacités que nous partageons avec les autres animaux. D’autres proposent que le volontaire au (...) sens propre soit uniquement humain, et qu’Aristote attribue le volontaire aux autres animaux seulement par métaphore. Un troisième groupe soutient qu’Aristote distingue implicitement le volontaire, que nous partageons avec les autres animaux, et la responsabilité morale, qui n’appartient qu’aux êtres rationnels. Je propose une alternative à ces approches habituelles. Je démontre que le volontaire chez Aristote fonctionne comme un genre, divisé en espèces rationnelle et non rationnelle. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Aristotle's On the Soul: A Critical Guide ed. by Caleb M. CohoeAttila HangaiCaleb M. Cohoe, editor. Aristotle's On the Soul: A Critical Guide. Cambridge: Cambridge University Press, 2022. Hardback, $99.99.Guiding readers through Aristotle's science of the soul, this volume covers many major topics of De Anima (DA) and addresses specific questions, including perennial interpretive problems. The self-contained chapters approach the text either by illuminating its context or by (...) elucidating key psychological concepts. While some contributions refer to relevant [End Page 318] positions by Aristotle's predecessors or contemporary philosophers, connections drawn to other Aristotelian texts predominate. Throughout, the emphasis is on philosophical questions. The result is a first-rate philosophical guide through this densely written treatise, which allows experienced readers of DA to deepen their understanding of Aristotelian psychology. Since most chapters approach interpretive issues from new angles and presuppose familiarity with the existing scholarship, beginners may want to start elsewhere.In Reeve's reading (chapter 1), Aristotle pursues dialectic in DA to define the soul as the first principle for the science of life. He construes dialectic as "going through puzzles and solving them by appeal to endoxa" (21), and equates it with induction from perceptual experience to knowledge of principles and causes. Contesting this view, Carter (chapter 2) argues that the physicist's method is not dialectical because the predecessors' views, conflicting as they are, do not constitute endoxa. Through close readings of DA II.2–5, he shows that Aristotle investigates earlier theories to assess how well they explain the main functions of the soul. One pertinent theory takes the soul to be attunement (harmonia). Shields (chapter 4) elucidates Aristotle's case for hylomorphism as an advance over the harmonia theory. Although harmonia (as the proper arrangement of parts) implies normativity, it falls short of rendering the soul as a final cause with its own good, so it cannot explain the unity of the body. Frey's chapter 5 on the soul's unity deals with this latter function. The problem of unity stems from the fact that each level in the hierarchy of souls—nutritive, perceptual, rational—can be defined independently, yet a posterior soul presupposes the existence of all prior ones. The key Frey uses to understand unity is potential presence. Just as a triangle is present potentially in a quadrangle—for division of the latter yields triangles—so too is the nutritive soul present potentially in the perceptual soul, although not due to a separating act. This, however, has counterintuitive implications: animal nutrition would be the function of a perceptual soul; furthermore, the nutritive soul of the embryo (in Frey's biological example) would first be present potentially (as undeveloped) and, once actualized (when developed), would revert to potentiality (at the development of the perceptual soul). Frey's other proposal is more promising. It turns on the notion of natural continuity: having an internal cause for a characteristic change with a unitary goal. Thus, the soul's unity for Frey (despite his reservations) seems to boil down to teleology: the soul sets a goal achieved through the manifestation of species-specific life functions. Invoking the biology of animal reproduction, Gelber (chapter 6) complements the teleological unity regarding the nutritive soul-part with the unity constituted by the continuity of the processes of nutrition, growth, and reproduction, namely, unity by material and efficient causes.Among the three contributions on reason (nous), Scheiter (chapter 3), examining its separability, breaks with the traditional interpretation and takes Aristotle to show (in DA III.4 and I.3) that reason is independent not only of bodily organs but of any magnitude (megethos). This envisages DA III.4–8 as an investigation into how reason functions as a different kind of capacity. It turns out, according to Kelsey's insightful chapter 11, that reason's actuality—insight (noēsis)—is the same as its intelligible object (noēton), and so intelligibility depends on separation from matter by the actuality of reason, making all and only the immaterial things intelligible and intelligent. Cohoe (chapter 12) draws the conclusion: human reason for Aristotle—being the defining part of the human soul, most... (shrink)

Many scholars have claimed that a well-known, allegedly ‘Rylean’ passage in DA I.4 shows that Aristotle does not think souls are subjects of mental states and activities. However, other scholars have argued against this and invoked other texts to support their rival claim that Aristotle does think souls are subjects of mental states and activities. This article articulates and defends an original interpretation of Aristotle’s position vis-à-vis this issue. In particular, this article argues that Aristotle thinks the souls of living (...) corporeal substances are ‘things that underlie’ (i.e., ὑποκɛίμɛνα for) various non-substantial features of the substances to which they belong, including whatever mental capacities those substances have. However, this does not entail that he thinks souls literally have the features they underlie, as if they themselves were alive and could engage in the kinds of mental activities (seeing, hearing, desiring, thinking, reasoning, etc.) that animals and humans can. In fact, there is good reason to think Aristotle does not think souls literally engage in such activities, despite his sometimes writing in a loose manner that suggests they do. (shrink)

The European tradition makes a sharp distinction between animism and science. On the basis of this distinction, either animism is reproved for failing to reach the heights of science, or science is reproved for failing to reach the heights of animism. In this essay, I draw on work in the history and philosophy and science, combined with a method from the sociology of scientific knowledge, to question the sharpness of this distinction. Along the way, I also take guidance from the (...) research of North American Indigenous scholars. As it turns out, there is a rich, if largely overlooked, tradition of Aristotelian animism running through the history of modern European science, and this tradition sometimes resonates with Indigenous perspectives. By challenging the entrenched distinction between animism and science, I aim to help reconcile ongoing tensions between Indigenous and European scientific groups, and so strengthen prospects for their mutually beneficial cooperation.

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)

This paper explains the motivation behind Aristotle’s appeal in Nicomachean Ethics 1154b7–9 to the physiologoi, who notoriously declare that animals are constantly in pain. It argues that the physiologoi are neither the critical target of this chapter nor invoked to verify Aristotle’s commitment to the imperfection of the human condition. Rather, despite doctrinal disagreement, they help Aristotle develop a naturalistic story about how ordinary people easily indulge in sensory pleasures.

abstract: I provide a novel interpretation of Aristotle's account of the unity of soul, treating it as resolving the apparent incompatibility of the existence of psychic parts and the soul's status as a unifying form. This incompatibility, I contend, rests on a problematic assumption: mereological actualism, or the claim that parts are actually distinct and prior to the whole. Aristotle successfully undermines actualism and formulates an alternative conception of parthood within De Anima 's figure-soul analogy. As triangles are only potentially (...) present within quadrilaterals, so lower psychic parts are potential parts of higher souls. This picture treats a soul not as a mere aggregate of capacities, but as essentially unified and prior to its parts. Finally, I argue that this picture can be illuminated and must be read against the background of his hylomorphic account of the unity of form given in Metaphysics H.6. (shrink)

Here is a fact about humans: we use our senses to pick up on things around us and our intellect to understand whatever is out there to be understood. In Mind and World in Aristotle’s De Anima, Kelsey argues that this fact is, in Aristotle’s view, in need of an explanation. He finds one in De Anima 3.8’s suggestion that “intelligence [is] form of forms, and sensibility form of sensibilia” (432a2–3; quoted on p. 2). Roughly, his proposal is that our (...) sensibility and intelligence “enter into the very idea” of their objects; they know them because they help make them what they are (20). -/- This is an admirably adventurous thesis, and Kelsey’s arguments for it are likewise so. A particular strength, in fact, is the way the book brings out what is at stake philosophically in familiar and seemingly obscure doctrines alike. Two highlights, which I discuss below, are its discussions of how Aristotle’s engagement with his predecessors shapes his questions (and then makes it hard to answer them) and of how his account of perceptible qualities helps him meet this challenge. This book is therefore a significant contribution to scholarship on the De Anima (DA), and it will be of great value to scholars working on Aristotle’s philosophy of mind. Part of what makes it valuable, moreover, is how it encourages us to ask better questions about core Aristotelian doctrines: while some of Kelsey’s proposals (especially his account of per se causation, which I discuss below) are provocative, they are always productively so.

q. 16 of John of Naples’ Quodlibet III – Utrum dolor vel passio damnatae animae separatae sit, sicut in subiecto immediato, in eius essentia vel potentia – evokes one of the most delicate debates, both from a theological and philosophical point of view, of scholastic eschatology between the end of the 13th century and the first decades of the 14th: that relating to the action of hellfire (considered, due to the auctoritas of Gregory the Great, corporeal and identical in essence (...) to sublunar fire) on an immaterial reality such as the soul in its state of separation (i.e. in the period between the individual death and the final judgement). The article retraces the way in which (in the well-known q. 2 of Quodlibet VI) John of Naples defends Thomas Aquinas from the suspicion of incurring, with his position, the condemnations of Tempier in 1270 and 1277, and how Aquinas himself tries to explain (especially in q. 26 of his Quaestiones disputatae de veritate) the passio or pain of the soul (both in the state of separation and in that of conjunction), through the double distinction between passio corporalis and passio animalis, and, within the former, between laesio and experimentalis perceptio laesionis. It then analyses q. 16 of Quodlibet III, in which John of Naples identifies the rational appetite – i.e. the will – as the immediate subject of the separate soul’s pain. In the appendix, an edition of John’s question is provided on the basis of the manuscripts Napoli, Biblioteca Nazionale, VII.B. 28 (= N) and Tortosa, Biblioteca de la Catedral, 244 (= T). (shrink)

For Aristotle, animals, by contrast to plants, possess a perceptual soul. However, there is disagreement concerning the point at which the perceptual soul is acquired, for him. On one influential interpretation, Aristotle thinks that the perceptual soul is acquired not during the initial formation of the embryo, but at some later stage of its development. On such interpretations of Aristotle’s view, the newly formed embryo is not yet an actual animal, but a plant-like living being or even inanimate matter. We (...) argue, by contrast, that Aristotle views the embryo, from the very beginning, as an actual animal exercising basic nutritive and perceptual functions. We show that this interpretation is consistent with Aristotle’s views on embryogenesis in the GA, HA, PA, and the Metaphysics. (shrink)

This dissertation is a study of the relationship between dunamis and energeia in Aristotle’s ontology. Throughout his writings, Aristotle employs these terms to uncover what I call a proto-phenomenological description of the different ways of being. While contemporary scholarship has suggested the significance of dunamis and energeia for Aristotle’s understanding of being, the relationship between these terms has often been interpreted as mutually exclusive. Accordingly, dunamis would be understood as subordinate to energeia, which would function as the sole primary term (...) of Aristotle’s ontology. I argue that it is a mistake to consider dunamis and energeia as non-reciprocal and subordinate terms. Furthermore, I suggest that this mistake often leads to an underestimation of the dynamic character of Aristotle’s proto-phenomenological account of being. To recover this dimension of Aristotle’s thinking, I claim that dunamis and energeia ought to be understood as reciprocal and co-constitutive terms characterized by a constant and dynamic interrelation. To defend this interpretation, I turn to Aristotle’s conceptions of nature, movement, and soul as discussed in the Metaphysics, Physics, and De Anima. I argue that each of these key terms provide a concrete illustration of how dunamis and energeia function as co-constitutive principles for the manifestation of the being of natural beings. I propose that this proto-phenomenological approach to being remains Aristotle’s most significant and enduring contribution to Western ontology. (shrink)

Caleb Cohoe helms another excellent entry in the Cambridge Critical Guides series. The volume consists of thirteen contributions, nominally ordered to proceed t.

Andrea Cesalpino is an important figure in the history of science. He demonstrated that blood circulates into heart from veins and from the heart to arteries, paving the way to Harvey’s complete description of blood circulation. Moreover, he was the founder of botany as a systematic discipline, which he based, rather than on the observation of accidental similarities of plants, on the discovery of their vegetative-generative principle. In philosophy, he attempted to conciliate the immortality of the soul (i.e., the form (...) of the body) with the existence of a unique immaterial intellect, which is individuated and multiplied in the singular souls that participate to it.

_Concept Formation_ is the final part of the trilogy _Forms of Representation in the Aristotelian Tradition_. It investigates some of the most perplexing and provocative discussions on conceptual thinking in the Greek, Latin, and Arabic reception of Aristotle’s psychology.

The discussions of conatus – force, tendency, effort, and striving – in early modern metaphysics have roots in Aristotle’s understanding of life as an internal experience of living force. This paper examines the ways that Spinoza’s conatus is consonant with Aristotle on effort. By tracking effort from his psychology and ethics to aesthetics, I show there is a conatus at the heart of the activity of the ψυχή that involves an intensification of power in a way which anticipates many of (...) the central insights of early modern and 20th century European philosophy. The first section outlines how Aristotle’s developmental conception of the soul as geometrically ordered lays the foundation for his understanding of effort. The developmental series of powers of the soul are analogous to the series of shapes in mathematics. The second section links the striving of the soul to the gradual acquisition of virtues as a directed activity unifying multiplicity. The third examines the paradigm of self-awareness that Aristotelian effort involves. In the final section I show how ancient Greek theories of music were founded on the experience of striving. The “nature” of music is defined by Aristoxenus, and Theophrastus, in relation to the passion and intentionality of the soul. The geometrical order, as a synthesis of elements in geometry, music, or ethics, is a generative process in which past elements are retained and reintegrated in later stages of development. It requires effort to think geometrically, and the progress of knowledge itself is an integral aspect of all effort. Effort is the lived and self-aware cause which, moving step by step in an orderly and deliberate way, grows and advances upon itself. For both Spinoza and Aristotle, effort is the immanent intelligence which accomplishes what is in the purview of its understanding. Thus, will, in this conception of effort, is not something we already possess innately, but emerges gradually by an effort aimed at improvement. (shrink)

In DA I.2–5, Aristotle offers a series of critical discussions of earlier Greek definitions of the soul. The status of these discussions and the role they play in the justification of Aristotle’s theory of soul in DA II–III is controversial. In contrast to a common view, I argue that these discussions are not dialectical but philosophical. I also contend that Aristotle does not consider earlier philosophical definitions of soul to be endoxa, but rather contradoxa – beliefs about which the many (...) and the wise disagree among themselves. Through an analysis of Plato’s and Empedocles’s definitions of soul, I show that these definitions are nevertheless treated by Aristotle as potential scientific principles for explaining two of the soul’s per se attributes: causing motion and cognition in animate bodies. The main role of the critical discussions in DA I.2–5 is to show that all such earlier definitions of soul fail this explanatory task. Nevertheless, I show that these chapters are not wholly aporetic. Aristotle makes progress by solving two scientific puzzles within them: whether the soul has spatial parts, and whether ‘soul’ refers to a uniform entity across biological species. (shrink)

I present an overview of On the Soul, Aristotle’s investigation into how psuchē (soul) explains biological phenomena in a unified way. This principle serves as a final, formal, and efficient cause of living activities. Soul needs specific consideration because it is a unique sort of form. It is responsible not just for giving living things their capacities, but also for when and how they exercise these capacities. Soul orders the ways in which living things grow, reproduce, move, and cognize the (...) world. It accounts for all the more specific capacities and activities of the living thing. Studying soul thus gives Aristotle the opportunity to make some of his most subtle distinctions about kinds of capacity and activity. Aristotle’s discussion of soul as cause also prepares the way for considering how it works together with body, as Aristotle does in the Parva Naturalia and biological works. I then present synopses of the chapters in this guide and discuss how they relate to one another. (shrink)

In DA I.1, Aristotle asks whether nous (understanding or reason) is chōristē (separable) and presents a separability condition: the soul is separable if it has some activity proper to it that is not shared with the body. I argue that Aristotle is speaking here of separability in being, not separability in account or taxonomical separation. In the case of the soul, this sort of separability would allow the soul to exist apart from the body. Met. Λ.3, GA II.3, and DA (...) III.4 suggest that Aristotle introduces the separability condition because understanding meets it. Reason is independent of the body in a way that no other power of the soul is. Nous alone is divine and separable. DA III.5 then situates this claim: there is an aspect of understanding that can only be active in connection with the body, but understanding is what it is and continues to be active apart from the body. This raises further questions about the life and ontological status of the sort of separated human nous Aristotle envisages. While figuring out its precise contours is difficult, Aristotle is, in fact, committed to the possibility of human intellectual activity continuing apart from the body. (shrink)

Aristotle's On the Soul aims to uncover the principle of life, what Aristotle calls psuchē. For Aristotle, soul is the form which gives life to a body and causes all its living activities, from breathing to thinking. Aristotle develops a general account of all types of living through examining soul's causal powers. The thirteen new essays in this Critical Guide demonstrate the profound influence of Aristotle's inquiry on biology, psychology and philosophy of mind from antiquity to the present. They deepen (...) our understanding of his key concepts, including form, reason, capacity, and activity. This volume situates Aristotle in his intellectual context and draws judiciously from his other works as well as the history of interpretation to shed light on his intricate views. It also highlights ongoing interpretive debates and Aristotle's continuing relevance. It will prove invaluable for researchers in ancient philosophy and the history of science and ideas. (shrink)

This chapter first argues against the widely accepted “mentalist” interpretation of Aristotle’s conception of the perception of external objects. On that view, the perception of objects results from an act of synthesis of the diverse perceptual input provided by the different sense modalities. I argue that Aristotle’s conception of perception does not require such mental “construction” of external objects. For him, we unfailingly perceive external objects by way of modally specific perception: perception without qualification is primarily of external 3-D objects, (...) while modally specific perception is of perceptual qualities. As the special senses cannot operate in isolation from the perceptual system as a whole, it follows that we see colors, hear sounds, etc., and thereby perceive the objects whose colors and sounds they are. The second part offers a causal interpretation of Aristotle’s definition of perception as “reception of the form without the matter,” according to which the causal history of sensory affection fixes the content of the resulting act of perception: perception is cognitive in virtue of being the matterless presence of external things’ qualities in the perceiver. (shrink)

The aim of this chapter is to explain Aristotle’s definition of the vegetative part of the soul in the De anima from a methodological point of view. I discuss Aristotle’s conception of the soul and his conception of “parts of the soul” before I turn to his definition of the vegetative part of the soul in De anima II 4. I argue that the definition of the vegetative capacity is deliberately abstract so as to cover its various activities under one (...) common heading. I also argue that the De anima deliberately avoids a positive and determinate description of the activity of the soul that is properly responsible for the vegetative functions, and that Aristotle offers such a positive and determinate description in his works dedicated to the actions and affections “common to body and soul”. (shrink)

According to Aristotle, the three main varieties of soul – nutritive, perceptual, and rational – are hierarchically ordered. I develop and defend an interpretation of the soul’s unity that centers on Aristotle’s attempt to explain this hierarchy’s organizing cause. Aristotle draws an analogy between this series of souls and the series of figures. I first elucidate the fundamental feature both series share: each series’ prior members are present in capacity in its posterior members. I do so by examining several other (...) cases – mathematical, biological, and physical – where Aristotle appeals to presence in capacity. I then argue that an organism’s living body is continuous by nature. That is, an organism’s soul is the principle, cause, and end of a single, articulate activity of living and each of an organism’s vital bodily movements are aspects or partial manifestations of this unitary, natural activity. This account of natural continuity is, I contend, the key to understanding what it is for one soul to be present in capacity in another. And this account of presence in capacity is, I contend, the key to understanding what it is for a soul that comprises parts to be a unity. (shrink)

This paper investigates the notion of ‘distributed cognition’—the idea that entities external to one’s organic brain participate in one’s overall cognitive functioning—and the challenges it poses to the notion of personhood. Related to this is also a consideration of the ever-increasing ways in which neuroprostheses replace and functionally replicate organic parts of the brain. However, the literature surrounding such issues has tended to take an almost exclusively physicalist approach. The common assumption is that, given that non-physicalist theories (chiefly, dualism, and (...) hylomorphism) postulate some form of immaterial ‘soul’, then they are immune from the challenges that these advances in cognitive science pose. The first aim of this paper, therefore, is to argue that this is not the case. The second aim of this paper is to attempt to elucidate a route available for the non-physicalists that will allow them to accept the notion of distributed cognition. By appealing to an Aristotelian framework, I propose that the non-physicalist can accept the notion of distributed cognition by appealing to the notion of ‘unitary life’ which I introduce, as well as to Aristotle’s dichotomy between active and passive mind.

The phenomenon of reflective awareness, i.e., perceiving that we perceive, has often been at the center of Aristotelian scholarship, whereas that of perceptual attention, i.e., focusing on something we perceive, has been much less studied. I examine in parallel the textual evidence for these phenomena and offer a concurrent analysis of them in order to understand better how Aristotle conceives them. I argue that the Aristotelian notion of the common sense lies at the basis of the explanation of perceptual attention (...) as much as of that of reflective awareness. In the former case, the common sense perceives the special or common perceptible that it pays attention to in its own right, whereas in the latter case it perceives the act of perceiving coincidentally along with the respective special or common perceptible. Following Aristotle, the Peripatetics defended the view that the phenomenon of reflective awareness is due to the common sense, but paid no heed to perceptual attention. On the other hand, the Neoplatonic commentators conflated the two phenomena and explained both of them by postulating either a rational character of the senses or an attentive part in the rational soul.

Historians have claimed that the two closely related concepts of animism and natural teleology were both decisively rejected in the Scientific Revolution. They tout Robert Boyle as an early modern warden against pre-modern animism. Discussing Avicenna, Aquinas, and Buridan, as well as Renaissance psychology, I instead suggest that teleology went through a slow and uneven process of rationalization. As Neoplatonic theology gained influence over Aristotelian natural philosophy, the meaning of animism likewise grew obscure. Boyle, as some historians have shown, exemplifies (...) this uneven process. There is an unresolved tension between his religious convictions and the implicit animism of his empirical practice. (shrink)

William Gilbert’s 1600 book, De magnete, greatly influenced early modern natural philosophy. The book describes an impressive array of physical experiments, but it also advances a metaphysical view at odds with the soon to emerge mechanical philosophy. That view was animism. I distinguish two kinds of animism – Aristotelian and Platonic – and argue that Gilbert was an Aristotelian animist. Taking Robert Boyle as an example, I then show that early modern arguments against animism were often effective only against Platonic (...) animism. In fact, unacknowledged traces of Aristotelian animism can be found in Boyle’s mechanical account of nature. This was Gilbert’s legacy. (shrink)

I examine Aristotle’s reasons in DA I.3 for rejecting the claim that understanding (nous) is a magnitude (megethos), an idea Aristotle associates most explicitly with Plato, who describes nous as a self-moving circle in the Timaeus. Aristotle shows that his definition of soul, on which soul is not a magnitude or body of any kind, can explain perception, thought, and motion better than his predecessor’s materialist accounts. But unlike perception and motion, nous is not actualized through the body nor does (...) it have a bodily organ, which makes nous a very different kind of soul capacity. Earlier thinkers, including Plato, already maintain that nous does not have a bodily organ, but they cannot explain how nous could operate or be a mover without being some sort of body itself. Even in the Timaeus, nous is described as being a kind of magnitude. But if nous were a magnitude of any kind, Aristotle claims it would not be able to think or reason. There is something about being a magnitude qua magnitude that makes reason impossible. His critique of Plato in I.3 prepares the way for his account of nous in DA III.4. (shrink)

We understand Aristotle’s soul–body hylomorphism better if we first understand the critical discussions of his predecessors which occupy most of the first book of his De Anima. Given that he regards his view as preferable to all earlier approaches, he must also think that his alternative, hylomorphism, avoids the pitfalls he identifies in those positions. In some cases, it is easy to see why he might think hylomorphism is defensible where they are not: for instance, he regards the reductively materialistic (...) views of the earliest natural philosophers as explanatorily impoverished. In other cases, however, this is far from clear. Aristotle highlights for special consideration the view that the soul is a harmonia (attunement) of the body, a view which, as was noted in antiquity, bears more than a passing resemblance to his own hylomorphism. It proves both difficult and instructive to determine, then, how he supposes hylomorphism avoids the problems he identifies in the doctrine of the soul as a harmonia. The core difference, it emerges, turns on Aristotle’s thoroughgoing teleology: the soul, he thinks, unlike a harmonia, has an intrinsic good toward which the body is orchestrated. (shrink)

By scholarly consensus, extant fragments from, and testimony about, Aristotle’s lost dialogue Eudemus provide strong evidence for thinking that Aristotle at some point defended the human soul’s unqualified immortality (either in whole or in part). I reject this consensus and develop an alternative, deflationary, speculative, but textually supported proposal to explain why Aristotle might have written a dialogue featuring arguments for the soul’s unqualified immortality. Instead of defending unqualified immortality as a doctrine, I argue, the Eudemus was most likely offering (...) a dramatically engaging propaedeutic to the sort of philosophical inquiry about the soul and its prospects that Aristotle pursues more scientifically in the De anima and Parva naturalia. (shrink)

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)

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 explain what Aristotle means when, after puzzling about the matter of motion in incomplete animals (those without sight, smell, hearing), he suggests in De Anima III 11.433b31–434a5 that just as incomplete animals are moved indeterminately, desire and phantasia are present in those animals, but present indeterminately. I argue that self-motion and its directing faculties in incomplete animals differ in degree but not in kind from those of complete animals. I examine how an object of desire differs for an incomplete (...) animal. Using a comparison with Aristotle’s account of recollection, especially in unfavorable circumstances, I describe indeterminate self-motion. Finally, I discuss implications for our understanding of Aristotle’s accounts of the faculties of the soul and incomplete animals. (shrink)

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.

Political theorists converge in identifying modern techniques of domination as habit-formative and psychologically invasive, in contrast to earlier, more blatantly coercive forms of repression. Putting Aristotle on tyranny in conversation with Michel Foucault on subject formation, this article argues for continuity across the pre- and postmodern divide. Through a close reading of the “three heads of tyranny” in Politics 5.11 (1314a13-29)—those being the tyrant’s efforts to form subjects who (1) have small thoughts (2) are distrustful of one another, and (3) (...) are incapable of action—I argue that central to Aristotle’s account of tyrannical domination is how tyrants cultivate the ethical vice of “small-souledness” ( Nicomachean Ethics 1123b7), thus producing subjects with humbled desires for a proportionate distribution of political power. This article deepens our appreciation of the social and psychological registers of Aristotle’s theorization of domination and gives reasons for continuing to take Aristotle’s insights into tyranny seriously today.

The definition of soul in De Anima ii 1 is usually thought to be inadequate, since Aristotle ends the chapter by saying the account has been sketched in outline and begins ii 2 by explaining the proper way to define. I argue instead that this is Aristotle’s considered definition of soul. I do so by examining the transitional material between ii 1 and ii 2, explaining the meaning of ‘in outline’ and how the examples of proper definitions that show the (...) cause—squaring in De Anima and thunder from Posterior Analytics—correspond to the definition of soul given in ii 1.

This volume is a detailed study of the concept of the nutritive capacity of the soul and its actual manifestation in living bodies in Aristotle and Aristotelianism. Aristotle’s innovative analysis of the nutritive faculty has laid the intellectual foundation for the increasing appreciation of nutrition as a prerequisite for the maintenance of life and health that can be observed in the history of Greek thought. According to Aristotle, apart from nutrition, the nutritive part of the soul is also responsible for (...) or interacts with many other bodily functions or mechanisms, such as digestion, growth, reproduction, sleep, and the innate heat. After Aristotle, these concepts were used and further developed by a great number of Peripatetic philosophers, commentators on Aristotle and Arabic thinkers until early modern times. This volume is the first of its kind to provide an in-depth survey of the development of this rather philosophical concept from Aristotle to early modern thinkers. It is of key interest to scholars working on classical, medieval and early modern psycho-physiological accounts of living things, historians and philosophers of science, biologists with interests in the history of science, and, generally, students of the history of philosophy and science.

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)
