We are used to discounting the river-gods and dryads of the Greeks as poetical fancies, and even the chief figures in the classical Pantheon-Venus, Minerva, Mars, and the rest-as allegories. But, forgetting that they once carried as much sanctity as our saints and divinities, we refrain from applying the same reasoning to our own objects of worship.

Many people assert that this abandonment of the god hypothesis means the abandonment of all religion and all moral sanctions. This is simply not true. But it does mean, once our relief at jettisoning an outdated piece of ideological furniture is over, that we must construct something to take its place.

Human potentialities constitute the world's greatest resource.

God is one among several hypotheses to account for the phenomena of human destiny, and it is now proving to be an inadequate hypothesis. To a great many people, including myself, this realization is a great relief, both intellectually and morally. 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.

Some day no one will have to work more than two days a week... The human being can consume so much and no more. When we reach the point when the world produces all the goods that it needs in two days, as it inevitably will, we must curtail our production of goods and turn our attention to the great problem of what to do with our new leisure.

Evolution is nothing but matter become conscious of itself.
