“Inferences and large dosages of imagination actually have allowed the construction of a far more adequate understanding of the cosmic and human past than earlier generations achieved. I believe that this is the central intellectual accomplishment of the twentieth century. Innumerable cosmologists, physicists, mathematicians, anthropologists, sociologists, historians, ecologists, ethologists, and other specialists have played their part; a few swashbuckling intellects led the way, and the outlines of an evolutionary worldview, uniting natural and human history, has begun to emerge. It may be convincing for generations to come—or again may not.”

Transhumanism (1957)
Context: The first thing that the human species has to do to prepare itself for the cosmic office to which it finds itself appointed is to explore human nature, to find out what are the possibilities open to it (including, of course, its limitations, whether inherent or imposed by the facts of external nature)... The great men of the past have given us glimpses of what is possible in the way of personality, of intellectual understanding, of spiritual achievement, of artistic creation. But these are scarcely more than Pisgah glimpses. We need to explore and map the whole realm of human possibility, as the realm of physical geography has been explored and mapped. How to create new possibilities for ordinary living? What can be done to bring out the latent capacities of the ordinary man and woman for understanding and enjoyment; to teach people the techniques of achieving spiritual experience (after all, one can acquire the technique of dancing or tennis, so why not of mystical ecstasy or spiritual peace?); to develop native talent and intelligence in the growing child, Instead of frustrating or distorting them?

Context: Frazer is much more savage than most of his savages, for they are not as far removed from the understanding of spiritual matter as a twentieth-century Englishman. His explanations of primitive practices are much cruder than the meaning of these practices themselves.
