The next paragraph is from Wikipedia:
Nietzsche's writing spans philosophical polemics, poetry, cultural
criticism, and fiction while displaying a fondness for aphorism and
irony. Prominent elements of his philosophy include his radical
critique of truth in favor of perspectivism; a genealogical critique
of religion and Christian morality and related theory of
master–slave morality; the aesthetic affirmation of existence in
response to the "death of God" and the profound crisis of nihilism;
the notion of Apollonian and Dionysian forces; and a
characterization of the human subject as the expression of competing
wills, collectively understood as the will to power. He also
developed influential concepts such as the Übermensch and the
doctrine of eternal return. In his later work, he became
increasingly preoccupied with the creative powers of the individual
to overcome cultural and moral mores in pursuit of new values and
aesthetic health.
