I go to nature to be soothed and healed, and to have my senses put in order.

The love of nature is a different thing from the love of science, though the two may go together.

I believe in a long, prolonged, derangement of the senses in order to obtain the unknown.

If I were to name the three most precious resources of life, I should say books, friends, and nature; and the greatest of these, at least the most constant and always at hand, is nature.

To find the universal elements enough; to find the air and the water exhilarating; to be refreshed by a morning walk or an evening saunter... to be thrilled by the stars at night; to be elated over a bird's nest or a wildflower in spring — these are some of the rewards of the simple life.

How many thorns of human nature are bristling conceits, buds of promise grown sharp for want of congenial climate.
