Tell your son to stop trying to fill your head with science - for to fill your heart with love is enough!

(Joan,1941) She wrote me a letter asking,"How can I read it?,Its so hard." I told her to start at the beginning and read as far as you can get until you're lost. Then start again at the beginning and keep working through until you can understand the whole book. And thats what she did

Why make yourself miserable saying things like, "Why do we have such bad luck? What has God done to us? What have we done to deserve this?" - all of which, if you understand reality and take it completely into your heart, are irrelevant and unsolvable. They are just things that nobody can know. Your situation is just an accident of life.

The "paradox" is only a conflict between reality and your feeling of what reality "ought to be."

It is necessary for the very existence of science that minds exist which do not allow that nature must satisfy some preconceived conditions.

The basis of action on love, the brotherhood of all men, the value of the individual... the humility of the spirit.

Although it is uncertain, it is necessary to make science useful. Science is only useful if it tells you about some experiment that has not been done; it is not good if it only tells you what just went on.
