Some day no one will have to work more than two days a week... The human being can consume so much and no more.

There are thus two tasks for the Mass Media division of Unesco, the one general, the other special. The special one is to enlist the press and the radio and the cinema to the fullest extent in the service of formal and adult education, of science and learning, of art and culture. The general one is to see that these agencies are used both to contribute to mutual comprehension between different nations and cultures, and also to promote the growth of a common outlook shared by all nations and cultures.

...any belief in supernatural creators, rulers, or influencers of natural or human process introduces an irreparable split into the universe, and prevents us from grasping its real unity.

God is one among several hypotheses to account for the phenomena of human destiny, and it is now proving to be an inadequate hypothesis.

It frees us to explore the real phenomena for which the God hypothesis seeks to account, to define them more accurately, and to work for a more satisfying set of concepts.

Evolution... is the most powerful and the most comprehensive idea that has ever arisen on Earth.
