We all think we know what emotion is, but when we try to explain it we realize that it remains a mysterious phenomenon. How can we know that a person is experiencing a given emotion? How can we communicate emotions to others? On a daily basis, with varying degrees of awareness, we ask ourselves similar questions, which have been feeding philosophical thought since ancient times. This book outlines some of the most significant ways in which such queries have been addressed, from Plato to contemporary neuroscience.
