Once, toward the close of his too brief life, Thoreau "signed on" again to an American ideal, and no man could have signed more nobly. It was the cause of Freedom, as represented by John Brown of Harper's Ferry. The French and Scotch blood in the furtive hermit suddenly grew hot. Instead of renouncing in disgust the "uncivil chaos called Civil Government," Thoreau challenged it to a fight. Indeed he had already thrown down the gauntlet in Slavery in Massachusetts, which Garrison had published in the Liberator in 1854. And now the death upon the scaffold of the old fanatic of Ossawatomie changed Thoreau into a complete citizen, arguing the case and glorifying to his neighbors the dead hero. "It seems as if no man had ever died in America before; for in order to die you must first have lived.... I hear a good many pretend that they are going to die.... Nonsense! I'll defy them to do it. They haven't got life enough in them. They'll deliquesce like fungi, and keep a hundred eulogists mopping the spot where they left off. Only half a dozen or so have died since the world began." Such passages as this reveal a very different Thoreau from the Thoreau who is supposed to have spent his days in the company of swamp-blackbirds and woodchucks. He had, in fact, one of the highest qualifications for human society, an absolute honesty of mind. "We select granite," he says, "for the underpinning of our houses and barns; we build fences of stone; but we do not ourselves rest on an underpinning of granite truth, the lowest primitive rock. Our sills are rotten.... In proportion as our inward life fails, we go more constantly and desperately to the post-office. You may depend upon it, that the poor fellow who walks away with the greatest number of letters, proud of his extensive correspondence, has not heard from himself this long time."
This hard, basic individualism was for Thoreau the foundation of all enduring social relations, and the dullest observer of twentieth century America can see that Thoreau's doctrine is needed as much as ever. His sharp-edged personality provokes curiosity and pricks the reader into dissent or emulation as the case may be, but its chief ethical value to our generation lies in the fact that here was a Transcendentalist who stressed, not the life of the senses, though he was well aware of their seductiveness, but the stubborn energy of the will.
