Agreements about what is good or not, are usually not worth much. It is very much like art, is it not an art to lead a good life?

There are two ways to live: you can live as if nothing is a miracle; you can live as if everything is a miracle. The most beautiful thing we can experience is the mysterious. It is the source of all true art and all science. He to whom this emotion is a stranger, who can no longer pause to wonder and stand rapt is awe, is as good as dead: his eyes are closed.

I think that only daring speculation can lead us further and not accumulation of facts.

Once you can accept the universe as matter expanding into nothing that is something, wearing stripes with plaid comes easy.

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.

The most precious things in life are not those you get for money.

To be sure, it is not the fruits of scientific research that elevate a man and enrich his nature, but the urge to understand, the intellectual work, creative or receptive.
