Two kinds of thinkers

It makes all the difference whether a thinker stands in a personal relationship to his problems, so that he possesses in them his destiny, his necessity and also his greatest happiness, or whether this relationship is 'impersonal': that is, he knows how to feel and grasp them only with the tentacles of cold, inquisitive thought. In the latter case nothing will result, so much is certain: for the grand problems, even if they let themselves be grasped, refuse to let themselves be retained by frogs and weaklings, that has been their taste from all eternity.

- Friedrich Nietzsche, The Gay Science
