Time itself comes in drops.

Most men have a good memory for facts connected with their own pursuits.

Our beliefs and our attention are the same fact.

To begin with, our knowledge grows in spots. The spots may be large or small, but the knowledge ever grows all over... What you first gain from them is probably a small amount of new information, a few new definitions, or distinctions, or points of view. But while these special ideas are being added, the rest of your knowledge stands still, and only gradually will you 'line up' your previous opinions with the novelties I am trying to instil, and modify to some slight degree their mass.

If you wish to upset the law that all crows are black, you mustn't seek to show that no crows are; it is enough if you prove one single crow to be white.

The function of ignoring, of inattention, is as vital a factor in mental progress as the function of attention itself.

The good we do today becomes the happiness of tomorrow.
