But the thought is one thing, the deed is another, and another yet is the image of the deed. The wheel of causality does not roll between them. - Friedrich Nietzsche

We have to cease to think, if we refuse to do it in the prison house of language; for we cannot reach further than the doubt which asks whether the limit we see is really a limit.

Altered opinions do not alter a man’s character (or do so very little); but they do illuminate individual aspects of the constellation of his personality which with a different constellation of opinions had hitherto remained dark and unrecognizable.

Thus the man who is responsive to artistic stimuli reacts to the reality of dreams as does the philosopher to the reality of existence; he observes closely, and he enjoys his observation: for it is out of these images that he interprets life, out of these processes that he trains himself for life. It is not only pleasant and agreeable images that he experiences with such universal understanding: the serious, the gloomy, the sad and the profound, the sudden restraints, the mockeries of chance, fearful expectations, in short the whole 'divine comedy' of life, the Inferno included, passes before him, not only as a shadow-play — for he too lives and suffers through these scenes — and yet also not without that fleeting sense of illusion; and perhaps many, like myself, can remember calling out to themselves in encouragement, amid the perils and terrors of the dream, and with success: 'It is a dream! I want to dream on!' Just as I have often been told of people who have been able to continue one and the same dream over three and more successive nights: facts which clearly show that our innermost being, our common foundation, experiences dreams with profound pleasure and joyful necessity.
