Every discovery and, indeed, every change of any sort is immoral, as
tending to unsettle men’s minds, and hence their custom and hence their
morals, which are the net residuum of their “mores” or customs.
Wherefrom it should follow that there is nothing so absolutely moral as
stagnation, except for this that, if perfect, it would destroy all mores
whatever. So there must always be an immorality in morality and, in like
manner, a morality in immorality. For there will be an element of
habitual and legitimate custom even in the most unhabitual and detestable
things that can be done at all.
