Thought is what we start from: the simple, intimate, immediate datum. Matter is the inferred thing, the mystery.

Stupidity is much the same all the world over. A stupid person's notions and feelings may confidently be inferred from those which prevail in the circle by which the person is surrounded. Not so with those whose opinions and feelings are an emanation from their own nature and faculties.

For many have but one resource to sustain them in their misery, and that is to think, "Circumstances have been against me, I was worthy to be something much better than I have been. I admit I have never had a great love or a great friendship; but that is because I never met a man or a woman who were worthy of it; if I have not written any very good books, it is because I had not the leisure to do so; or, if I have had no children to whom I could devote myself it is because I did not find the man I could have lived with. So there remains within me a wide range of abilities, inclinations and potentialities, unused but perfectly viable, which endow me with a worthiness that could never be inferred from the mere history of my actions." But in reality and for the existentialist, there is no love apart from the deeds of love; no potentiality of love other than that which is manifested in loving; there is no genius other than that which is expressed in works of art.

Much can be inferred about a man from his mistress: in her one beholds his weaknesses and his dreams.
