The most important part of our lives-our sensations, emotions, desires, and aspirations-takes place in a universe of illusions which science can attenuate or destroy, but which it is powerless to enrich.

There is no such thing as a dangerous woman; there are only susceptible men.

And the thing which is missing is love, some feeling for, as well as some understanding of, the inclusive community of rocks and soils, plants and animals, of which we are a part.

How anyone can profess to find animal life interesting and yet take delight in reducing the wonder of any animal to a bloody mass of fur or feathers?

In the long run our boasted control of nature is a delusion.

Science has always promised two things not necessarily related; an increase first in our powers, second in our happiness or wisdom, and we have come to realize that it is the first and less important of the two promises which it has kept most abundantly.

If we are deprived of hope as well as fear, we are compensated by being given an almost endless patience for enduring or simply for waiting.
