"Die Philosophie der Freiheit: Grundzüge einer modernen Weltanschauung" by Rudolf Steiner is a philosophical work published in 1894. It explores whether human beings can truly be free. Part One examines how thinking forms the basis of freedom and knowledge. Part Two develops what Steiner calls "ethical individualism," analyzing the conditions necessary for freedom and proposing a moral philosophy. Through introspective observation, Steiner argues that freedom exists when we become conscious of our motives and act through our thinking activity.
