Nietzsche on Conduct

Twilight Of The Idols - Expeditions of an Untimely Man 46

'When a philosopher keeps silent it can be loftiness of soul; when he contradicts himself, it can be love; a politeness which tells lies is possible in men of knowledge. Not without subtlety was it said: 'It is unworthy of great spirits to spread abroad the agitation they feel.': only one has to add that not to fear the unworthiest things can likewise be greatness of soul. A woman who loves sacrifices her honour; a man of knowledge who 'loves' sacrifices perhaps his humanity; a god who loved became a Jew...'
Supreme rule of conduct- even when alone one mustn't 'let oneself go', to live among men who don't 'let themselves go'. 'It is decisive for the fortune of nations and of mankind that culture is inaugurated in the right place- not in the soul but in the body. 'Goeth conceived of a strong, highly cultured human being, skilled in all physical accomplishments, who, keeping himself in check and having reverence for himself, dares to allow himself the whole compass and wealth of naturalness, who is strong enough for this freedom; a man of tolerance, not out of weakness, but out of strength, because he knows how to employ to his advantage what would destroy an average nature; a man to whom nothing is forbidden, except it be weakness, whether that weakness be called vice or virtue.... A spirit thus emancipated stands in the midst of the universe with a joyful and trusting fatalism, in the faith that only what is separate and individual may be rejected, that in the totality everything is redeemed and affirmed- he no longer denies.... But such a faith is the highest of all possible faiths: I have baptised it with the name Dionysus.'
The aphorism is a form of eternity. (To say in ten sentences what everyone else says in a book and what everyone else does not say in a book.)
