The book offers a comprehensive, accurate, and textually supported description of the philosophical views of emotion from the fifth century BC to the fifteenth century AD. The wealth of references to primary sources, coupled with the consciousness in the presentation of numerous theoretical accounts, makes the monograph an ideal point of reference for the study of ancient and medieval approaches to emotion ... the book is, I believe, of interest to anyone currently working in the philosophy of emotions

Knuutilla's book steers with a sure hand over the rough waters of the philosophical debates of ancient and medieval thought.

Anthony Hatzimoysis, Mind

Knuuttila has done an immense amount of research, covering an extraordinarily wide variety of sources ... it will be a fine resource for any who wish to see how ideas of the soul, and the place of emotions and other faculties and powers in it, evolved from classical antiquity to the high Middle Ages. It is the work of a scholar very much at home in the mediaeval scholastic tradition, who brings to the task a deep understanding of the kinds of reasoning in which these thinkers were engaged. Knuuttila's book will be an excellent starting point for any future investigations of the history of the emotions.
