These complexities, and difficulties of interpretation, have led some to talk of the uneasy co-existence of different “models of the soul” in Galen (see Manuli 1986, 1988; Singer 2013: 18–33). Certainly, any study of Galen’s theoretical accounts of the soul must involve an analysis of many different texts, both those specifically devoted to the theory of the psuchē, and ones which touch on it in a wide range of different contexts (physiological, pathological, dietetic, pharmacological); it must also take account of the fact that these texts belong to quite different technical genres and draw upon a variety of traditions, intellectual approaches and specialist concepts and vocabularies; and of the fact that the focus of the argument is radically different in some of these different contexts. Again, in any attempt to summarize Galen’s “philosophy of mind”, the caution should be made that his primary motivation and intellectual concern throughout nearly all these texts are those of the practising physician, not those of the theoretical philosopher. (For a comprehensive account of the pathological and medical aspect of Galen’s work on the psuchē see now Devinant 2020.)
