It is not so important where one settles down. The best thing is to follow your instincts without too much reflection.

That deep emotional conviction of the presence of a superior reasoning power, which is revealed in the incomprehensible universe, forms my idea of God.

People will not disarm step by step; they will disarm at one blow or not at all.

I believe in mystery and, frankly, I sometimes face this mystery with great fear. In other words, I think that there are many things in the universe that we cannot perceive or penetrate, and that also we experience some of the most beautiful things in life only in a very primitive form. Only in relation to these mysteries do I consider myself to be a religious man.

I believe, indeed, that overemphasis on the purely intellectual attitude, often directed solely to the practical and factual, in our education, has led directly to the impairment of ethical values. I am not thinking so much of the dangers with which technical progress has directly confronted mankind, as of the stifling of mutual human considerations by a 'matter-of-fact' habit of thought which has come to lie like a killing frost upon human relations. Without 'ethical culture' there is no salvation for humanity.

If something is in me which can be called religious then it is the unbounded admiration for the structure of the world so far as our science can reveal it.

It is the same with people as it is with riding a bike. Only when moving can one comfortably maintain one's balance.
