Adam Smith

A vast similitude interlocks all, All spheres, grown, ungrown, small, large, suns, moons, planets, All distances of place however wide, All distances of time, all inanimate forms, All souls, all living bodies though they be ever so different, or in different worlds, All gaseous, watery, vegetable, mineral processes, the fishes, the brutes This vast similitude spans them, and always has spannd, And shall forever span them and compactly hold and enclose them.

From 'On the Beach at Night Alone' by American poet Walt Whitman, first published in the collection Leaves of Grass (1856).
