This book comprises a collection of original papers that reflect on the philosophical understanding of emotions from Greek thinkers to the present day. Central figures discussed include Aristotle, Aquinas, Ockham, Descartes, Malebranche, Spinoza, Hobbes, Hume, Shaftesbury, Hutcheson, Kant, Schiller, Schopenhauer, Nietzsche, James, Brentano, Stumpf, Scheler, Heidegger, and Sartre. Central issues include the taxonomy of the emotions; the distinction between emotions, passions, feelings, and moods; the relation between the emotions and reason; the relationship between the self and the emotions. At a meta-philosophical level, the collection also raises issues about the value of historical study of the discipline, and what light it can shed on contemporary concerns.
