The vestiges of the depreciation of Nature through moral transcendence: The value of disinterestedness, the cult of altruism; the belief in a reward in the play of natural consequences; the belief in "goodness" and in genius itself, as if the one, like the other, were the result of disinterestedness; the continuation of the Church's sanction of the life of the citizen; the absolutely deliberate misunderstanding of history (as a means of educating up to morality) or pessimism in the attitude taken up towards history (the latter is just as much a result of the depreciation of Nature, as is that pseudo-justification of history, that refusal to see history as the pessimist sees it).

"Morality for its own sake"—this is an important step in the denaturalisation of morals: in itself it appears as a final value. In this phase religion has generally become saturated with it: as, for instance, in the case of Judaism. It likewise goes through a phase in which it separates itself from religion, and in which no God is "moral" enough for it: it then prefers the impersonal ideal.... This is how the case stands at present.
"Art for Art's sake": this is a similarly dangerous principle: by this means a false contrast is lent to things—it culminates in the slander of reality ("idealising" into the hateful). When an ideal is severed from reality, the latter is debased, impoverished, and calumniated. "Beauty for Beauty's sake," "Truth for Truth's sake," "Goodness for Goodness' sake"—these are three forms of the evil eye for reality.
Art, knowledge, and morality are means: instead of recognising a life-promoting tendency in them, they have been associated with the opposite of Life—with "God"—they have also been regarded as revelations of a higher world, which here and there transpires through them....
"Beautiful" and "ugly," "true" and "false," "good" and "evil"—these things are distinctions and antagonisms which betray the preservative and promotive measures of Life, not necessarily of man alone, but of all stable and enduring organisms which take up a definite stand against their opponents. The war which thus ensues is the essential factor: it is a means of separating things, leading to stronger isolation....

Moral naturalism: The tracing back of apparently independent and supernatural values to their real "nature"—that is to say, to natural immorality, to natural "utility," etc.
Perhaps I may designate the tendency of these observations by the term moral naturalism: my object is to re-translate the moral values which have apparently become independent and unnatural into their real nature—that is to say, into their natural "immorality."
N.B.—Refer to Jewish "holiness" and its natural basis. The case is the same in regard to the moral law which has been made sovereign, emancipated from its real feature (until it is almost the opposite of Nature).
