Context: In this moment when we face horizons and conflicts wider than ever before, we want our resources, the ways of strength. We look again to the human wish, its faiths, the means by which the imagination leads us to surpass ourselves.
If there is a feeling that something has been lost, it may be because much has not yet been used, much is still to be found and begun.
Everywhere we are told that our human resources are all to be used, that our civilization itself means the uses of everything it has — the inventions, the histories, every scrap of fact. But there is one kind of knowledge — infinitely precious, time-resistant more than monuments, here to be passed between the generations in any way it may be: never to be used. And that is poetry.

Context: Electromagnetic fields are not of the mind... Creation may be spiritual in origin, but that doesn't mean that everything created is spiritual. How can I explain such things to you? Let us accept the world is a mystery. Nature is neither solely material nor entirely spiritual. Man, too, is more than flesh and blood; otherwise, no religions would have been possible. Behind each cause is still another cause; the end or the beginning of all causes has yet to be found. Behind each cause is still another cause; the end or the beginning of all causes has yet to be found. Yet, only one thing must be remembered: there is no effect without a cause, and there is no lawlessness in creation".
