Friedrich Nietzsche: To see differently.....

... 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 “contemplation without interest” (which is a nonsensical absurdity), but as the ability to control one’s Pro and Con and to dispose of them, so that one knows how to employ a variety of perspectives and affective interpretations in the service of knowledge. … There is only a perspective seeing, only a perspective “knowing”; and the more affects we allow to speak about one thing, the more eyes, different eyes, we can use to observe one thing, the more complete will our “concept” of this thing, our “objectivity,” be.” (Nietzsche, On the Genealogy of Morals: 555)
