"What Is Man? and Other Essays" by Mark Twain is a collection that grapples with the big questions about what makes us human. Through insightful essays and conversations, particularly between an Old Man and a Young Man, the book questions whether we truly have free will or if we're just complex machines reacting to the world around us. The conversation highlights the idea that our thoughts and actions might not be as original as we think, but instead, guided by our experiences and surroundings. It discusses how everything we do, even the good stuff, might boil down to trying to make ourselves feel good, challenging readers to rethink their motives and the very nature of human existence.
