Unless we have courage to recognize cruelty for what it is - whether its victim is human or animal - we cannot expect things to be much better in the world.

If a child is to keep alive his inborn sense of wonder, he needs the companionship of at least one adult who can share it, rediscovering with him the joy, excitement, and mystery of the world we live in.

Until we have courage to recognize cruelty for what it is - whether its victim is human or animal - we cannot expect things to be much better in the world. There can be no double standard. We cannot have peace among men whose hearts find delight in killing any living creature. By every act that glorifies or even tolerates such moronic delight in killing, we set back the progress of humanity.

There is something infinitely healing in the repeated refrains of nature.

When we go down to the low-tide line, we enter a world that is as old as the earth itself - the primeval meeting place of the elements of earth and water, a place of compromise and conflit and eternal change.

The control of nature is a phrase conceived in arrogance.

Those who contemplate the beauty of the earth find reserves of strength that will endure as long as life lasts. There is something infinitely healing in the repeated refrains of nature -- the assurance that dawn comes after night, and spring after winter.
