A man who is convinced of the truth of his religion is indeed never tolerant. At the least, he is to feel pity for the adherent of another religion but usually it does not stop there. The faithful adherent of a religion will try first of all to convince those that believe in another religion and usually he goes on to hatred if he is not successful. However, hatred then leads to persecution when the might of the majority is behind it.

The single most important decision any of us will ever make is whether or not to believe the universe is friendly.

Without changing our pattern of thought, we will not be able to solve the problems we created with our current patterns of thought

Today we must abandon competition and secure cooperation. This must be the central fact in all our considerations of international affairs; otherwise we face certain disaster. Past thinking and methods did not prevent world wars. Future thinking must prevent wars...The stakes are immense, the task colossal the time is short. But we may hope- we must hope- that man's own creation, man's own genius, will not destroy him.

We act as though comfort and luxury were the chief requirements of life. All that we need to make us happy is something to be enthusiastic about.
