Nietzsche's famous work Beyond Good and Evil follows up on the morality ideas presented in his prior publication, Thus Spoke Zarathustra (1883), and further challenges the accepted standards previous philosophers held surrounding morality. This nine part work, which includes an entire chapter (Chapter IV) of short aphorisms, has become a mainstay in philosophical thinking.
