Warm summer sun, shine kindly here. Warm southern wind, blow softly here. Green sod above, lie light, lie light. Good night, dear Heart, Good night, good night.

The plastic virtues: purity, unity, and truth, keep nature in subjection.

Each man must look to himself to teach him the meaning of life. It is not something discovered: it is something molded.

Nature does nothing uselessly.

The sky is the part of creation in which nature has done for the sake of pleasing man.

The aim of life is some way of living, as flexible and gentle as human nature; so that ambition may stoop to kindness, and philosophy to condor and humor. Neither prosperity nor empire nor heaven can be worth winning at the price of a virulent temper, bloody hands, an anguished spirit, and a vain hatred of the rest of the world.

Nature is commanded by obeying her.

Men may change their climate, but they cannot change their nature. A man that goes out a fool cannot ride or sail himself into common sense.

All men by nature desire to know.

Nature... is nothing but the inner voice of self-interest.
