The paper is a discussion of P. M. S. Hacker, The Passions: A Study of Human Nature (2018). After a general presentation of the book I mostly focus on its first part, which deals with categories and concepts essential to the philosophy of the emotions. Next I pass on to two subsequent parts of the book devoted to particular emotions. After a brief overview I say more, by way of exemplification, on the chapter on love. I end with a final assessment.
