Ansell-Pearson goes on;

"For Nietzsche, one of the most important aspects of the attempt to think through the problem of Nihilism is the need to develop an understanding of how new values can be created and fashioned through the conjunction of philosophical legislation and political power ...

"We must see the Revaluation of Values, not in terms of some arcane academic exercise, but as crucial to the cultivation of Great Politics ...

"Nietzsche is adamant that it is only an Aristocratic society which can justify terrible but noble sacrifices and experiments, for only this kind of society is geared towards, not justice and compassion, but the continual self-overcoming of man - and of life.
In a note from the time of BGE he speaks of the cultivation of a Master Race which will constitute the future Masters of the Earth. It will form a 'new tremendous aristocracy based on the severest self-legislation' and employ 'democratic Europe as its most pliant and supple instrument for taking control of the destinies of the Earth' (WP 960) ...

"He looks forward to the masters of humanity in terms of a group of 'Artist Tyrants' who look upon man as a sculptor works upon his stone ..."
[Ansell-Pearson ib.,]

The above notion of Great Politics as a "sacrifice and experiment" has prompted some to see sm as such;

"sm can be understood as a phenomenon of post-Nietzschean culture, more specifically as a Nietzschean 'experiment'. In Nietzsche's posthumously published notes we find the exclamation: 'Let us make experiments to attain knowledge! Perhaps mankind will perish during them! All right!' ... "
[sm as a Nietzschean Experiment, K.R. Fischer]

Fischer alights on this prophetic quote from The Joyful Wisdom;

"So far, science has not yet built its Cyclopic buildings, but the time for that, too, will come".
