Art has a double face, of expression and illusion,...

The bare recollection of anger kindles anger.

Audacity augments courage hesitation, fear.

An angry father is most cruel towards himself.

Youth is the gift of nature, but age is a work of art.

My age and health will never allow me to realize the dream of art I've been pursuing all my life.

The hours I spend with you I look upon as sort of a perfumed garden, a dim twilight, and a fountain singing to it. You and you alone make me feel that I am alive. Other men it is said have seen angels, but I have seen thee and thou art enough.

An artist is always alone - if he is an artist. No, what the artist needs is loneliness.

The credit of advancing science has always been due to individuals and never to the age.

Science cannot tell theology how to construct a doctrine of creation, but you can't construct a doctrine of creation without taking account of the age of the universe and the evolutionary character of cosmic history.

The older generation had greater respect for land than science. But we live in an age when science, more than soil, has become the provider of growth and abundance. Living just on the land creates loneliness in an age of globality.

Before anything else, we need a new age of Enlightenment. Our present political systems must relinquish their claims on truth, justice and freedom and have to replace them with the search for truth, justice, freedom and reason.

A bad manner spoils everything, even reason and justice a good one supplies everything, gilds a No, sweetens a truth, and adds a touch of beauty to old age itself.

The reason for the sadness of this modern age and the men who live in it is that it looks for the truth in everything and finds it.

It is error alone which needs the support of government. Truth can stand by itself.
