Philosophical reflection on the emotions has a long history stretching back to classical Greek thought, even though at times philosophers have marginalized or denigrated them in favour of reason. Fourteen leading philosophers here offer a broad survey of the development of our understanding of the emotions. The thinkers they discuss 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 metaphilosophical level, the collection also raises issues about the value of historical study of the discipline, and what light it can shed on contemporary concerns. Thinking about the Emotions is a fascinating and illuminating collective study of how philosophers have grappled with this most intriguing part of our nature as beings who feel as well as think and act.
