What gives your life meaning? Plato and Aristotle said, "Everything has an essence." Jean- Paul Satre said, "What if we exist first?" Nihilism is the belief that life is meaningless, founded by German philosopher Friedrich Nietzsche. Existence preceeds essence, that is the frame work of existentialism. They say our birth happens first, then we have to find our own essence. We have to write our own essence through the way we choose to live, but we have no predetermined purpose. Some existentialist are atheists, some are theists. Any thoughts on this?
