Essays in Metaphysics: German philosopher Martin Heidegger presents two lectures in which he explores the nature of identity in the history of metaphysics. He offers illuminating insights on vital issues like technology, religion, language, history, and more. The Emotions: French philosopher Jean-Paul Sartre attempts to understand the role emotions play in the human psyche.
