In contrast to the typical Enlightenment view of ancient Greek culture as noble, simple, elegant and grandiose, Nietzsche believed the Greeks were grappling with pessimism. The universe in which we live is the product of great interacting forces; but we neither observe nor know these as such. What we put together as our conceptions of the world, Nietzsche thought, never actually addresses the underlying realities. It is human destiny to be controlled by the darkest universal realities and, at the same time, to live life in a human-dreamt world of illusions.
