I have found, for example, that if I have to write upon sum rather difficult topic, the best plan is to think about it with very great intensity-the greatest intensity of which I am capable-for a few hours or days, and at the end of that time give orders, so to speak (to my subconscious mind) that the work is to proceed underground. After some months I return consciously to the topic and find that the work has been done.

When I was a child . . . Only virtue was prized, virtue at the expense of intellect, health, happiness, and every mundane good.

So long as there is death there will be sorrow, and so long as there is sorrow it can be no part of the duty of human beings to increase its amount, in spite of the fact that a few rare spirits know how to transmute it.

I have come to realize that an early symptom of approaching mental illness is the belief that one's work is terribly important. If you consider your work very important you should take a day off.

Christ . . . said that a man who had looked after a woman lustfully had sinned as much as the man who had seduced her. How absurd!

Although this may seem a paradox, all exact science is dominated by the idea of approximation. When a man tells you that he knows the exact truth about anything, you are safe in inferring that he is an inexact man. Every careful measurement in science is always given with the probable error ... every observer admits that he is likely wrong, and knows about how much wrong he is likely to be.

People are said to believe in God, or to disbelieve in Adam and Eve. But in such cases what is believed or disbelieved is that there is an entity answering a certain description. This, which can be believed or disbelieved is quite different from the actual entity (if any) which does answer the description. Thus the matter of belief is, in all cases, different in kind from the matter of sensation or presentation, and error is in no way analogous to hallucination. A hallucination is a fact, not an error; what is erroneous is a judgment based upon it.
