Our nineteenth century is the age of tools. They
grow out of our structure. “Man is the metre of all
things,” said Aristotle; “the hand is the instrument
of instruments, and the mind is the form of forms.”
The human body is the magazine of inventions, the
patent office, where are the models from which every
hint was taken. All the tools and engines on earth
are only extensions of its limbs and senses.

—Works and Days: Emerson

Th’ invention all admir’d, and each, how he
To be th’ inventor miss’d; so easy it seem’d,
Once found, which yet unfound most would have thought
Impossible.
