Ancient philosophical theories of soul are in many respects sensitive to ways of speaking and thinking about the soul psuchê] that are not specifically philosophical or theoretical. We therefore begin with what the word ‘soul’ meant to speakers of Classical Greek, and what it would have been natural to think about and associate with the soul. We then turn to various Presocratic thinkers, and to the philosophical theories that are our primary concern, those of Plato (first in the Phaedo, then (...) in the Republic), Aristotle (in the De Anima or On the Soul ), Epicurus, and the Stoics. These are by far the most carefully worked out theories of soul in ancient philosophy. Later theoretical developments — for instance, in the writings of Plotinus and other Platonists, as well as the Church Fathers — are best studied against the background of the classical theories, from which, in large part, they derive.

The Brute Within proceeds in three parts, the first two (amounting to half the book) on Plato and the third on Aristotle. Each part, as well as the book itself, has an Introduction in which Lorenz helpfully signals what he is up to; the author frequently (though sometimes repetitively) summarizes his argument as he goes along. There is no mistaking his central claims: that in both Plato and Aristotle there are three types of desires--reason, spirit and appetite--such that the last (...) two may motivate conduct without any participation in reason at all. In human beings, reason may itself motivate conduct and also may share information with appetite and spirit to modify behavior. (shrink)

Hendrik Lorenz presents a comprehensive study of Plato's and Aristotle's conceptions of non-rational desire. They see this as something that humans share with animals, and which aims primarily at the pleasures of food, drink, and sex. Lorenz explores the cognitive resources that both philosophers make available for the explanation of such desires, and what they take rationality to add to the motivational structure of human beings. In doing so, he finds conceptions of the mind that are coherent and deeply integrated (...) with both philosophers' views about such topics as the relation between body and soul, or the nature of the virtues.
