Nietzsche's influence on contemporary philosophical thought is clear, to the point that the debate over the value of his philosophy in the broader history of Western and human thought has been surpassed. He managed to invert all fundamental values by philosophizing with a hammer, swapping positions, contents, and methods; the highest became the lowest, good became evil and weakness, and the path of return transformed into recurrence. He also dislodged traditional concepts from their long-held positions where they had become unthinking axioms, such as earth, sky, body, soul, the real, the apparent, and being. Moreover, he created new concepts by imbuing them with vibrant content like nihilism, the Übermensch (Superman), and the will to power. He also achieved new cognitive breakthroughs that were not previously subjects of research and contemplation, prompting many subsequent philosophers to respond to his propositions and work to complete his theories by drawing the ultimate conclusions from his premises.

While the profound impact of Nietzschean thought on contemporary philosophy is a philosophical given, this justifies the multitude of studies on his thought and even his life, making a comprehensive grasp of them a daunting task for any researcher, regardless of their diligence. An interesting point to note when reviewing the literature on Nietzsche is that every scholar who selects a topic for study concludes that this specific topic is the essential entry point into his philosophy. This has led to what might be called the 'interpretive literature' surrounding Nietzsche's philosophy. Between various interpreters, debate and disagreement have arisen about the nature and essence of his philosophy: Is it truly a moral philosophy? A metaphysical one? A new religion? Or an aesthetic theory? The range of interpretations remains open and multifaceted. It can be affirmed that every perspective presented is justified, correct, and coherent, as Nietzsche's extensive writings are sufficient to support any viewpoint or interpretation. This, in fact, is a hallmark of authentic texts; they are open to interpretation and justification from all angles, even when interpretations are contradictory, such as those of Jaspers and Camus, or Heidegger and Odoiev.
