The ambiguous word, base his own law on “chance”;

And, even while he used it, there would move

Before his eyes in every flake of colour,

Inlaid upon the butterfly’s patterned wing,

Legions of atoms wheeling each to its place

In ever constant law; and he knew well

That, even in the living eye that saw them,

The self-same Power that bound the starry worlds

Controlled a myriad atoms, every one

An ordered system; and in every cloud
