Regarding mutual tolerance: It is negative in one sense, but positive in another. It absolutely forbids us to be forward in pronouncing on the meaninglessness of forms of existence other than our own; and it commands us to tolerate, respect, and indulge those whom we see harmlessly interested and happy in their own ways, however unintelligible these may be to us. Hands off.

There is but one unconditional commandment ... to bring about the very largest total universe of good which we can see.

If merely 'feeling good' could decide, drunkenness would be the supremely valid human experience.

It is our attitude at the beginning of a difficult task which, more than anything else, will affect its successful outcome.

What a teacher needs to know about psychology "might almost be written on the palm of one's hand."

The most ancient parts of truth . . . also once were plastic. They also were called true for human reasons. They also mediated between still earlier truths and what in those days were novel observations. Purely objective truth, truth in whose establishment the function of giving human satisfaction in marrying previous parts of experience with newer parts played no role whatsoever, is nowhere to be found. The reasons why we call things true is the reason why they are true, for to be true means only to perform this marriage-function.

I myself believe that the evidence for God lies primarily in inner personal experiences.
