One of the leading twentieth-century French existentialist philosophers examines how human emotions shape our existence. In The Emotions: Outline of a Theory, French philosopher Jean-Paul Sartre attempts to understand the role emotions play in the human psyche. Sartre analyzes fear, lust, anguish, and melancholy while asserting that human beings begin to develop emotional capabilities from a very early age, which helps them identify and understand the emotions’ names and qualities later in life. Helping to complete the circle of Sartre’s many theories on existentialism, this vital piece of literature is a must-have for the philosopher-in-training’s collection.
