Philosophy is at once the most sublime and the most trivial of human pursuits. It works in the minutest crannies and it opens out the widest vistas. It “bakes no bread”, as has been said, but it can inspire our souls with courage.

First… a new theory is attacked as absurd; then it is admitted to be true, but obvious and insignificant; finally it is seen to be so important that its adversaries claim that they themselves discovered it.

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

We have to be ready to live today by what truth we can get today and be ready tomorrow to call it falsehood.

Our minds thus grow in spots; and like grease-spots, the spots spread. But we let them spread as little as possible: we keep unaltered as much of our old knowledge, as many of our old prejudices and beliefs, as we can. We patch and tinker more than we renew. The novelty soaks in; it stains the ancient mass; but it is also tinged by what absorbs it.

Truth happens to an idea. It becomes true, is made true by events.
