“What precious drops are those
Which silently each other's track pursue,
Bright as young diamonds in their infant dew?”

1840s, Essays: First Series (1841), Compensation
Context: The universe is represented in every one of its particles. Every thing in nature contains all the powers of nature. Every thing is made of one hidden stuff; as the naturalist sees one type under every metamorphosis, and regards a horse as a running man, a fish as a swimming man, a bird as a flying man, a tree as a rooted man. Each new form repeats not only the main character of the type, but part for part all the details, all the aims, furtherances, hindrances, energies, and whole system of every other. Every occupation, trade, art, transaction, is a compend of the world, and a correlative of every other. Each one is an entire emblem of human life; of its good and ill, its trials, its enemies, its course and its end. And each one must somehow accommodate the whole man, and recite all his destiny.
The world globes itself in a drop of dew.
