The extreme weakness of quantum gravitational effects now poses some philosophical problems; maybe nature is trying to tell us something new here: maybe we should not try to quantize gravity.

I walk every day, and I look at the mountains and the fields and the small city, and I say: ‚Oh my God, what a blessing.‘ Then you realise it’s important to put it in a context beyond this woman, this man, this city, this country, this universe.

The environment that we call society is created by past generations; we accept it, as it helps us to maintain our greed, possessiveness, illusion.

God has cared for these trees, saved them from drought, disease, avalanches, and a thousand tempests and floods. But he cannot save them from fools.

There are nights when the wolves are silent and only the moon howls.

Every particular in nature, a leaf, a drop, a crystal, a moment of time is related to the whole, and partakes of the perfection of the whole.

Nature is an infinite sphere of which the center is everywhere and the circumference nowhere.

Art is not merely an imitation of the reality of nature, but in truth a metaphysical supplement to the reality of nature, placed alongside thereof for its conquest.

I am proud to have been born in Iowa. Through the eyes of a ten-year-old boy, it was a place of adventure and daily discoveries – the wonder of the growing crops, the excitements of the harvest, the journeys to the woods for nuts and hunting, the joys of snowy winters, the comfort of the family fireside, of good food and tender care.

If one way be better than another, that you may be sure is nature’s way.

When we go out to the country and just sit there, what we’re really doing is just switching off various kinds of alertness that we don’t have to use. When we do that, we are stopping being defensive.
