We should begin to entertain doubts concerning a man if we heard that he required reasons in order to remain respectable: we should, in any case, certainly avoid his society. The little word "for" in certain cases may be compromising; sometimes a single "for" is enough to refute one. If we should hear, in course of time, that such-and-such an aspirant for virtue was in need of bad reasons in order to remain respectable, it would not conduce to increasing our respect for him. But he goes further; he comes to us, and tells us quite openly: "You disturb my morality, with your disbelief, Mr. Sceptic; so long as you cannot believe in my bad reasons,—that is to say, in my God, in a disciplinary Beyond, in free will, etc.,—you put obstacles in the way of my virtue.... Moral, sceptics must be suppressed: they prevent the moralisation of the masses."

Our most sacred convictions, those which are permanent in us concerning the highest values, are judgments emanating from our muscles.

Morality in the valuation of races and classes.—In view of the fact that the passions and fundamental instincts in every race and class express the means which enable the latter to preserve themselves (or at least the means which have enabled them to live for the longest period of time), to call them "virtuous" practically means:
That they change their character, shed their skins, and blot out their past.
It means that they should cease from differentiating themselves from others.
It means that they are getting to resemble each other in their needs and aspirations—or, more exactly, that they are declining....
It means that the will to one kind of morality is merely the tyranny of the particular species, which is adapted to that kind of morality, over other species: it means a process of annihilation or general levelling in favour of the prevailing species (whether it be to render the non-prevailing species harmless, or to exploit them); the "Abolition of Slavery"—a so-called tribute to "human dignity"; in truth, the annihilation of a fundamentally different species (the undermining of its values and its happiness).
