Under "Morality" I understand a system of valuations which is in relation with the conditions of a creature's life.

Formerly it was said of every form of morality, "Ye shall know them by their fruits." I say of every form of morality: "It is a fruit, and from it I learn the Soil out of which it grew."

I have tried to understand all moral judgments as symptoms and a language of signs in which the processes of physiological prosperity or the reverse, as also the consciousness of the conditions of preservation and growth, are betrayed—a mode of interpretation equal in worth to astrology, prejudices, created by instincts (peculiar to races, communities, and different stages of existence, as, for instance, youth or decay, etc.).
Applying this principle to the morality of Christian Europe more particularly, we find that our moral values are signs of decline, of a disbelief in Life, and of a preparation for pessimism.
My leading doctrine is this: there are no moral phenomena, but only a moral interpretation of phenomena. The origin of this interpretation itself lies beyond the pale of morality.
What is the meaning of the fact that we have imagined a contradiction in existence? This is of paramount importance: behind all other valuations those moral valuations stand commandingly. Supposing they disappear, according to what standard shall we then measure? And then of what value would knowledge be, etc. etc.???

A point of view: in all valuations there is a definite purpose: the preservation of an individual, a community, a race, a state, a church, a belief, or a culture.—Thanks to the fact that people forget that all valuing has a purpose, one and the same man may swarm with a host of contradictory valuations, and therefore with a host of contradictory impulses. This is the expression of disease in man as opposed to the health of animals, in which all the instincts answer certain definite purposes.
