Nourished by the prolific conflict of contradictions that permeated his life, Nietzsche bequeathed to us a wealth of problematic ideas. The series of questions these give rise to unfold here in the form of a philosophical essay. Two axes structure this book: a consideration of the will to power as an ontological hypothesis that refers to a plurality of life, and, at the same time, a reinterpretation of this hypothesis as indistinguishable from its becoming in nature and in human history, where particular lifeworlds arise.
