One may return to the place of his birth, He cannot go back to his youth.

One goes to Nature only for hints and half-truths. Her facts are crude until you have absorbed them or translated them ... It is not so much what we see as what the thing seen suggests.

One may summon his philosophy when they are beaten in battle, not till then.

The budget for nuclear forces in the United States is on the order of $25 billion or so. That includes warheads, delivery systems, command and control; does not include environmental clean-up, which is another maybe $10 billion or so. So that's about 5% of the U.S. military budget.

One of the hardest lessons we have to learn in this life, and one that many persons never learn, is to see the divine, the celestial, the pure, in the common, the near at hand-to see that heaven lies about us here in this world.

Natural history is a matter of observation; it is a harvest which you gather when and where you find it growing. Birds and squirrels and flowers are not always in season, but philosophy we have always with us. It is a crop which we can grow and reap at all times and in all places and it has its own value and brings its own satisfaction.

Life is a struggle, but not a warfare.
