Where Goodness Begins Friedrich Nietzsche

Where bad eyesight can no longer see the evil impulse as such, on account of its refinement, there man sets up the kingdom of goodness; and the feeling of having now gone over into the kingdom of goodness brings all those impulses (such as the feelings of security, of comfortableness, of benevolence) into simultaneous activity, which were threatened and confined by the evil impulses. Consequently, the duller the eye so much the further does goodness extend! Hence the eternal cheerfulness of common people and of children! Hence the gloominess and grief (allied to the bad conscience) of great thinkers.
