Beyond Good and Evil is a philosophical work by Friedrich Nietzsche, published in 1886, in which he expands on ideas introduced in Thus Spake Zarathustra. The book critiques traditional moral values and the concept of objective truth, arguing that these are social constructs that have been imposed by religious and philosophical systems. Nietzsche challenges the binary distinction between "good" and "evil," advocating for a "revaluation of all values" and promoting the idea that individuals should create their own values based on their will to power. Nietzsche's critique of conventional morality and his emphasis on individualism and self-overcoming have influenced existentialism, postmodernism, and various strands of 20th-century philosophy.
