Put your outspread hand over the Carlin Canyon, Nevada unconformity and your fingers span roughly forty million years- the time that it took to bevel down the first set of mountains and deposit the younger layers on top. What is forty million years? Enough time for a small predatory dinosaur to evolve into a bird. Enough time for a four-legged, deer-like mammal to evolve into a whale. And far more than enough time to turn an ape-like creature in eastern Africa into a big-brained biped who can marvel at such things.

Able to do anything he wanted, Watson devoted the rest of his life to just that. He traveled the world, read widely, and took a degree in geology at MIT for the simple satisfaction of improving his brain. He then started a shipyard, which quickly grew to employ four thousand men, producing a scale of stress and obligation way beyond anything he wished for, so he sold the business, converted to Islam, and became a follower of Edward Bellamy, a radical philosopher and quasi communist who for a short period in the 1880s enjoyed phenomenal esteem and popularity.

He died, contented and rich, at his winter home on Pass-Grille Key, Florida, just shy of his eighty-first birthday in 1934.
