Does the soul have parts? What kind of parts? And how do all the parts make together a whole? Many ancient, medieval and early modern philosophers discussed these questions, thus providing a mereological analysis of the soul. Their starting point was a simple observation: we tend to describe the soul of human beings by referring to different types of activities (perceiving, imagining, thinking, etc.). Each type of activity seems to be produced by a special part of the soul. But how can a simple, undivided soul have parts? Classical thinkers gave radically different answers to this question. While some claimed that there are indeed parts, thus assigning an internal complexity to the soul, others emphasized that there can only be a plurality of functions that should not be conflated with a plurality of parts. The eleven chapters reconstruct and critically examine these answers. They make clear that the metaphysical structure of the soul was a crucial issue for ancient, medieval and early modern philosophers.

Investigates Plato's account of the tripartite soul, looking at how the theory evolved over the Republic, Phaedrus and Timaeus.

Knowing Persons is an original study of Plato's account of personhood. For Plato, embodied persons are images of a disembodied ideal. The ideal person is a knower. Hence, the lives of embodied persons need to be understood according to Plato's metaphysics of imagery. For Gerson, Plato's account of embodied personhood is not accurately conflated with Cartesian dualism. Plato's dualism is more appropriately seen in the contrast between the ideal disembodied person and the embodied one than in the contrast between mind or soul and body. This study argues that Plato's analysis of personhood is intended to cohere with his two-world metaphysics as well as a radical separation of knowledge and belief. Gerson demonstrates that Plato's account of persons plays a key role not just in his theory of mind, but in his theory of knowledge, his metaphysics, and his ethics. A proper understanding of Plato's account of persons must therefore place it in the context of his doctrines in these areas. Knowing Persons fills a significant gap by showing the way to such an understanding.

This book is devoted to the last part of Aristotle’s collection of short treatises known today as the Parva Naturalia, i.e. the treatise On Youth and Old Age, on Life and Death, on Respiration. In the three main sections of the book, the author offers a translation, a commentary and a thorough analysis of this work. The author argues in favour of the unity of the work and contextualises its ideas within Aristotle’s corpus and the medical tradition of his time. After an Introduction to the nature of the work and its significance for the history of natural philosophy and science, a new English translation follows, along with a detailed commentary of Chapters 1-6, which combines philosophical discussion with philological observations. The book includes four interpretive essays, which tackle problems related to the whole treatise on a more philosophical basis, including questions about the structure and unity of the work, the organisation of the material, Aristotle’s methodological principles, his aims and target audience as well as the relevance of his selected themes to the thematic agenda of some Hippocratic writings. This book is of interest to students and researchers in Aristotle’s psychophysiology, and his views about the embodied mind, as well as to anyone concerned with the history of natural philosophy and science more generally.

This volume focuses on the under-explored topic of emotions' implications for ancient medical theory and practice, while it also raises questions about patients' sentiments. Ancient medicine, along with philosophy, offer unique windows to professional and scientific explanatory models of emotions. Thus, the contributions included in this volume offer comparative ground that helps readers and researchers interested in ancient emotions pin down possible interfaces and differences between systematic and lay cultural understandings of emotions. Although the volume emphasizes the multifaceted links between medicine and ancient philosophical thinking, especially ethics, it also pays due attention to the representation of patients' feelings in the extant medical treatises and doctors' emotional reticence. The chapters that constitute this volume investigate a great range of medical writers including Hippocrates and the Hippocratics, and Galen, while comparative approaches to medical writings and philosophy, especially Plato, Aristotle, and the Stoics, dwell on the notion of wonder/admiration (thauma), conceptualizations of the body and the soul, and the category pathos itself. The volume also sheds light on the metaphorical uses of medicine in ancient thinking.

Nicholas D. Smith presents an original interpretation of the Republic, considering it to be a book about knowledge and education. Over the course of Summoning Knowledge in Plato's Republic, he argues for four main theses. Firstly, the Republic is not just a work that has a lot to say about education; it is a book that depicts Socrates as attempting to engage his interlocutors in such a way as to help to educate them and also engages us, the readers, in a way that helps to educate us. Secondly, Plato does not suppose that education, properly understood, should have as its primary aim putting knowledge into souls that do not already have it. Instead, the education Plato discusses, represents occurring between Socrates and his interlocutors, and hopes to achieve in his readers is one that aims to arouse the power of knowledge in us and then to begin to train that power always to engage with what is more real, rather than what is less real. Thirdly, Plato's conception of knowledge is not the one typically presented in contemporary epistemology. It is, rather, the power of conceptualization by the use of exemplars. And finally, Plato engages this power of knowledge in the Republic in a way he represents as only a kind of second-best way to engage knowledge - and not as the best way, which would be dialectic. Instead, Plato uses images that summon the power of knowledge to begin the process by which the power may become fully realized.

Philosophers and doctors from the period immediately after Aristotle down to the second century CE were particularly focussed on the close relationships of soul and body; such relationships are particularly intimate when the soul is understood to be a material entity, as it was by Epicureans and Stoics; but even Aristotelians and Platonists shared the conviction that body and soul interact in ways that affect the well-being of the living human being. These philosophers were interested in the nature of the soul, its structure, and its powers. They were also interested in the place of the soul within a general account of the world. This leads to important questions about the proper methods by which we should investigate the nature of the soul and the appropriate relationships among natural philosophy, medicine, and psychology. This volume, part of the Symposium Hellenisticum series, features ten scholars addressing different aspects of this topic.
