“Custom represents the experiences of men of earlier times as to what they supposed was useful and harmful – but the [morality] applies, not to these experiences as such, but to the age, the sanctity, the indiscussability of the custom.

And so, this feeling is a hindrance to the acquisition of new experiences and corrections of customs: that is to say, morality is a hindrance to the creation of newer and better customs. [Morality] makes stupid.” ? Nietzsche
