Science goes its own way in spite of our likes and dislikes, but Thoreau's likes and dislikes determined everything for him. He was stoical, but not philosophical. His intellect had no free play outside his individual predilection. Truth as philosophers use the term, was not his quest but truth made in Concord. Thoreau writes that when he was once asked by the Association for the Advancement of Science what branch of science he was especially interested in, he did not reply because he did not want to make himself the laughing-stock of the scientific community, which did not believe in a science which deals with the higher law--his higher law, which bears the stamp of Henry Thoreau. He was an individualist of the most pronounced type. The penalty of this type of mind is narrowness; the advantage is the personal flavor imparted to the written page. Thoreau's books contain plenty of the pepper and salt of character and contrariness; even their savor of whim and prejudice adds to their literary tang. When his individualism becomes aggressive egotism, as often happens, it is irritating; but when it gives only that pungent and personal flavor which pervades much of "Walden," it is very welcome. Thoreau's critics justly aver that he severely arraigns his countrymen because they are not all Thoreaus--that they do not desert their farms and desks and shops and take to the woods. What unmeasured contempt he pours out upon the lives and ambitions of most of them! Need a nature-lover, it is urged, necessarily be a man-hater? Is not man a part of nature?--averaging up quite as good as the total scheme of things out of which he came? Cannot his vices and shortcomings be matched by a thousand cruel and abortive things in the fields and the woods? The fountain cannot rise above its source, and man is as good as is the nature out of which he came, and of which he is a part. Most of Thoreau's harsh judgments upon his neighbors and countrymen are only his extreme individualism gone to seed. An extremist he always was. Extreme views commended themselves to him because they were extreme. His aim in writing was usually "to make an extreme statement." He left the middle ground to the school committees and trustees. He had in him the stuff of which martyrs and heroes are made. In John Brown he recognized a kindred soul. But his literary bent led him to take his own revolutionary impulses out in words. The closest he came to imitation of the hero of Harper's Ferry and to defying the Government was on one occasion when he refused to pay his poll-tax and thus got himself locked in jail overnight. It all seems a petty and ignoble ending of his fierce denunciation of politics and government, but it no doubt helped to satisfy his imagination, which so tyrannized over him throughout life. He could endure offenses against his heart and conscience and reason easier than against his imagination.
