Let us guard against saying that there are laws in nature. There are merely necessities: there is no one who commands, no one whoobeys, no one who transgresses. Once you understand that there are no purposes, then you also understand that nothing is accidental: for it is only in a world of purposes that the word "accident" makes sense.
It is the mark of an educated mind to rest satisfied with the degree of precision which the nature of the subject admits and not to seek exactness where only an approximation is possible.
Upon the purple tree-tops far away, and on the green height near at hand up which the shades were slowly creeping, there was an equal hush. Between the real landscape and its shadow in the water, there was no division; both were so untroubled and clear, and, while so fraught with solemn mystery of life and death, so hopefully reassuring to the gazer's soothed heart, because so tenderly and mercifully beautiful.
Man carries the world in his head, the whole astronomy and chemistry suspended in a thought. Because the history of nature is charactered in his brain, therefore he is the prophet and discoverer of her secrets. Every known fact in natural science was divined by the presentiment of somebody, before it was actually verified.
Mathematics would certainly have not come into existence if one had known from the beginning that there was in nature no exactly straight line, no actual circle, no absolute magnitude.
All conservatives are such from personal defects. They have been effiminated by position of nature, born halt and blind, through luxury of their parents, and can only, like invalids, act on the defensive.
Today, more than ever before, life must be characterized by a sense of Universal responsibility, not only nation to nation and human to human, but also human to other forms of life.
Nature is one with rapine, a harm no preacher can heal; The Mayfly is torn by the swallow, the sparrow speared by the shrike, And the whole little wood where I sit is a world of plunder and prey.
Every rational creature has all nature for his dowry and estate. It is his, if he will. He may divest himself of it; he may creepinto a corner, and abdicate his kingdom, as most men do, but he is entitled to the world by his constitution.
