"Art includes everything that stimulates the desire to live; science, everything that sharpens the desire to know. Art, even the most disinterested, the most disembodied, is the auxiliary of life. Born of the sensibility, it sows and creates it in its turn. It is the flower of life and, as seed, it gives back life. Science, or to use a broader term, knowledge, has its end in itself, apart from any idea of life and propagation of the species. Intelligence, that sublimation of the sensibility, that organ of the need to know, is sterilized sensibility. To know, and to know still more--the instinct for knowledge is insatiable, because the subject of knowledge is limitless."
"Recently, the Germans have developed a tendency to prefer the so-called first (youthful) style of great artists to their mature works. Could it be that they do not realize that their aesthetic criteria, generally speaking, are juvenile?"
"I had, as I told you, a great passion while still almost a child. When it was over, I divided myself in two, placing on one side the soul I kept for Art, and on the other, my body, which would have to fend for itself."
"Art for art's sake? I should think so, and more so than ever at the present time. It is the one orderly product which our middlingrace has produced. It is the cry of a thousand sentinels, the echo from a thousand labyrinths, it is the lighthouse which cannot be hidden ... it is the best evidence we can have of our dignity."
