"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."

“The deeper our insight into the methods of nature . . . the more incredible the popular Christianity seems to us.”
