 Particularly as knowers, let us not be ungrateful toward such resolute reversals of the familiar perspectives and valuations with which the spirit has raged against itself all too long… : to see differently in this way for once, to want to see differently, is no small discipline and preparation of the intellect for its future “objectivity”—the latter understood not as “disinterested contemplation” (which is a non-concept and absurdity), but rather as the capacity to have one’s Pro and Contra in one’s power, and to shift them in and out, so that one knows how to make precisely the difference in perspectives and affective interpretations useful for knowledge. (GM III, 12)
