Religion is usually nothing but a supplement to or even a substitute for education, and nothing is religious in the strict sense which is not a product of freedom. Thus one can say: The freer, the more religious; and the more education, the less religion.

That which reminds us of nature and thus stimulates a feeling for the infinite abundance of life is beautiful. Nature is organic,and therefore the highest beauty is forever vegetative; and the same is true for morality and love.

If you want to penetrate into the heart of physics, then let yourself be initiated into the mysteries of poetry.

Philosophy is the true home of irony, which might be defined as logical beauty: for wherever men are philosophizing in spoken or written dialogues, and provided they are not entirely systematic, irony ought to be produced and postulated; even the Stoics regarded urbanity as a virtue.
