The world, nature, human beings, do not move like machines. The edges are never clear-cut, but always frayed. Nature never draws a line without smudging it.
It is not necessarily those lands which are the most fertile or most favored in climate that seem to me the happiest, but those in which a long struggle of adaptation between man and his environment has brought out the best qualities of both.
How often we must remember the art of the surgeon, which, in replacing the broken bone, contents itself with releasing the parts from false position; they fly into place by the action of the muscles. On this art of nature all our arts rely.
On the motionless branches of some trees, autumn berries hung like clusters of coral beads, as in those fabled orchards where the fruits were jewels . . .
Genius detects through the fly, through the caterpillar, through the grub, through the egg, the constant individual; through countless individuals the fixed species; through many species the genus; through all genera the steadfast type; through all the kingdoms of organized life the eternal unity.

Man carries the world in his head, the whole astronomy and chemistry suspended in a thought.

Every known fact in natural science was divined by the presentiment of somebody, before it was actually verified.
I thought as I rode in the cold pleasant light of Sunday morning how silent & passive nature offers, every morn, her wealth to man; she is immensely rich, he is welcome to her entire goods, which he speaks no word, only leaves over doors ajar, hall, store room, & cellar. He may do as he will: if he takes her hint & uses her goods, she speaks no word; if he blunders & starves, she says nothing.
The prayer of the farmer kneeling in his field to weed it, the prayer of the rower kneeling with the stroke of his oar, are true prayers heard throughout nature.
Refrain to-night; And that shall lend a kind of easiness To the next abstinence, the next more easy; For use almost can change the stamp of nature, And either master the devil or throw him out With wondrous potency.
But the moon came slowly up in all her gentle glory, and the stars looked out, and through the small compass of the grated window, as through the narrow crevice of one good deed in a murky life of guilt, the face of Heaven shone bright and merciful. He raised his head; gazed upward at the quiet sky, which seemed to smile upon the earth in sadness, as if the night, more thoughtful than the day, looked down in sorrow on the sufferings and evil deeds of men; and felt its peace sink deep into his heart.
