Morality is neither rational nor absolute nor natural. World has known many moral systems, each of which advances claims universality; all moral systems are therefore particular, serving a specific purpose for their propagators or creators, and enforcing a certain regime that disciplines human beings for social life by narrowing our perspectives and limiting our horizons.
Friedrich NietzscheThat is the most extreme form of nihilism: nothingness (the "meaningless") eternally!
Friedrich NietzscheDo ask yourself why you, the individual, exist, and if you can get no other answer try for once to justify the meaning of your existence as it were a posteriori by setting before yourself an aim, a goal, a 'to this end', an exalted and noble 'to this end'.
Friedrich Nietzsche
