Sublime

John Muir is remembered primarily as a no-nonsense conservationist and the founding president of the Sierra Club, but he was also a bold adventurer, a fearless scrambler of peaks, glaciers, and waterfalls whose best-known essay includes a riveting account of nearly falling to his death, in 1872, while ascending California’s Mt. Ritter.

In Paris later, at the Museum of Natural History (the Jardin des Plantes), with the blessing and counsel of the great Georges Cuvier, he undertook his vast, illustrated Recherches sur les Poissons Fossiles, at a time when fewer than a dozen generic types of fossil fish had been named and he was all of twenty-four.

“Stout ropes to check him, and stout oars to guide.” he sent for Aristotle, the most renowned philosopher of the age, to be his son’s tutor, and paid him a handsome reward for doing so.
