Nietzsche tried to save the reality as life on earth and recover the true meaning of reality against all the anti-realistic and anti-natural transcendences.
Nietzsches ontology, epistemology, ethics, political philosophy and theory of art are all based on reality, not on transcendental ideal. The occasions meant by Nietzsches concept of reality encompass all the moving and changing things in the universe including the life of organisms, the world of eternal recurrence, the world of mental-physical experiences, the interior and exterior of existence as a will to power, nature, time and space, the world of consciousness and unconsciousness, history, and political and cultural reality. From Nietzsches own perspective, reality refers to the world of becoming and event, that is to say, life against an illusory transcendental being of the eternal immutability. It is the reality that constitutes constantly becoming and changing world and the power of the worlds source. The Western metaphysics after Parmenides and Plato is defined as retreat to ideal and denial of reality according to Nietzsche. Nietzsche reads the real history, power, and will to domination from the transcendental idealism which denies life of becoming by supposing the world of eternal immutability. Nietzsche tried to save the reality as life on earth and recover the true meaning of reality against all the anti-realistic and anti-natural transcendences. The reason why the reality was an important theme to Nietzsche is that spirit should be based on reality, nature, and life, neither on transcendental ideal nor the universals for the creation of new value which has not existed so far and is able to enhance and sublimate the life of humankind.
