This volume is the first in English to provide a full, systematicinvestigation into Aristotle’s criticisms of earlier Greek theories ofthe soul from the perspective of his theory of scientific explanation.Some interpreters of the De Anima have seen Aristotle’s criticismsof Presocratic, Platonic, and other views about the soul as unfair ordialectical, but Jason W. Carter argues that Aristotle’s criticisms are infact a justified attempt to test the adequacy of earlier theories in termsof the theory of scientific knowledge he advances in the PosteriorAnalytics. Carter proposes a new interpretation of Aristotle’s confrontationswith earlier psychology, showing how his reception of otherGreek philosophers shaped his own hylomorphic psychology and ledhim to adopt a novel dualist theory of the soul–body relation. Hisbook will be important for students and scholars of Aristotle, ancientGreek psychology, and the history of the mind–body problem.jason w. carter is Teaching Fellow in philosophy at the Universityof Edinburgh. His work has been published in journals includingPhronesis and the Journal of the History of Philosophy.
