Thus, Kierkegaard criticizes all systematic philosophies which attempt to know life or the truth of existence via theories and objective knowledge about reality.   As Kierkegaard claims, human truth is something that is continually occurring, and a human being cannot find truth separate from the subjective experience of one's own existing, defined by the values and fundamental essence that consist of one's way of life.   Nietzsche Friedrich Nietzsche believed the search for truth, or 'the will to truth', was a consequence of the will to power of philosophers.   He thought that truth should be used as long as it promoted life and the will to power, and he thought untruth was better than truth if it had this life enhancement as a consequence.     As he WROTE  in Beyond Good and Evil, "The falseness of a judgment is to us not necessarily an objection to a judgment...     The question is to what extent it is life-advancing, life-preserving, species-preserving, perhaps even species-breeding..." (aphorism 4).   He proposed the will to power as a truth only because, according to him, it was the most life-affirming and sincere perspective one could have.   Robert Wicks discusses Nietzsche's basic view of truth as follows "(...)   Some scholars regard Nietzsche's 1873 unpublished essay, "On Truth and Lies in a Nonmoral Sense" as a keystone in his thought.
