To consider hypotheses is surely always better than to dogmatize ins blaue hinein

True ideas are those that we can assimilate, validate, corroborate, and verify. False ideas are those that we cannot. That is the practical difference it makes to us to have true ideas; that therefore is the meaning of truth, for it is all that truth is known as.

... A rule of thinking which would absolutely prevent me from acknowledging certain kinds of truth if those ... truths were really there, would be an irrational rule.

If you give appreciation to people, you win their goodwill. But more important than that, practicing this philosophy has made a different person of me.

A new idea is first condemned as ridiculous and then dismissed as trivial, until finally, it becomes what everybody knows.

Since belief is measured by action, he who forbids us to believe religion to be true, necessarily also forbids us to act as we should if we did believe it to be true.

So to feel brave, act as if we were brave, use all our will to that end...and a courage-fit will very likely replace the fit of fear.
