““The need of theory is supported by the eros of the philosopher. It is not the expression of his will to conquer nature. Therefore, the joys of contemplation are "immediate enjoyments," joys that belong intrinsically to contemplation, and they come without further setting of goals or justification to the one receptive to them. They are not tied to social use, neither dependent upon the opinion of others nor gained from the expectation of future glory. The love for the observation of nature, for the observation of the details of the structure in which nature becomes comprehensible, of the order in which nature is articulated, of the spectacle nature provides for one who takes an interest in its objects, who lets its forms, colors, and sounds affect him, this love accords with the love of oneself. Both discourage highfalutin plans to change the world by the transformation of nature. Both impose moderation on the philosopher. He will be especially adequate to his desire to "contribute" something "to this beautiful system" by his conceiving it as a "system" and as "beautiful." The contribution most his own is that he has the whole in view; that he sees things and beings within the horizon of the whole, that he investigates and orders them as parts, that he knows himself as a part and reflects on his relation to the whole or that he poses the question of the whole. But if he wants to keep the question of the whole in view, he may not lose himself. To conceive the "beautiful system," he must devote himself to it in detail and again return to himself. To be able to observe nature, he may not blend into it. Observation requires both proximity and distance.””
