That may be reason good enough to abstain from tea; but when we go on to find the same man, on the same or similar grounds, abstain from nearly everything that his neighbours innocently and pleasurably use, and from the rubs and trials of human society itself into the bargain, we recognise that valetudinarian healthfulness which is more delicate than sickness itself. We need have no respect for a state of artificial training. True health is to be able to do without it. Shakespeare, we can imagine, might begin the day upon a quart of ale, and yet enjoy the sunrise to the full as much as Thoreau, and commemorate his enjoyment in vastly better verses. A man who must separate himself from his neighbours' habits in order to be happy, is in much the same case with one who requires to take opium for the same purpose. What we want to see is one who can breast into the world, do a man's work, and still preserve his first and pure enjoyment of existence.
Thoreau's faculties were of a piece with his moral shyness; for they were all delicacies. He could guide himself about the woods on the darkest night by the touch of his feet. He could pick up at once an exact dozen of pencils by the feeling, pace distances with accuracy, and gauge cubic contents by the eye. His smell was so dainty that he could perceive the foetor of dwelling-houses as he passed them by at night; his palate so unsophisticated that, like a child, he disliked the taste of wine - or perhaps, living in America, had never tasted any that was good; and his knowledge of nature was so complete and curious that he could have told the time of year, within a day or so, by the aspect of the plants. In his dealings with animals, he was the original of Hawthorne's Donatello. He pulled the woodchuck out of its hole by the tail; the hunted fox came to him for protection; wild squirrels have been seen to nestle in his waistcoat; he would thrust his arm into a pool and bring forth a bright, panting fish, lying undismayed in the palm of his hand. There were few things that he could not do. He could make a house, a boat, a pencil, or a book. He was a surveyor, a scholar, a natural historian. He could run, walk, climb, skate, swim, and manage a boat. The smallest occasion served to display his physical accomplishment; and a manufacturer, from merely observing his dexterity with the window of a railway carriage, offered him a situation on the spot. "The only fruit of much living," he observes, "is the ability to do some slight thing better." But such was the exactitude of his senses, so alive was he in every fibre, that it seems as if the maxim should be changed in his case, for he could do most things with unusual perfection. And perhaps he had an approving eye to himself when he wrote: "Though the youth at last grows indifferent, the laws of the universe are not indifferent, BUT ARE FOR EVER ON THE SIDE OF THE MOST SENSITIVE."
Thoreau had decided, it would seem, from the very first to lead a life of self-improvement: the needle did not tremble as with richer natures, but pointed steadily north; and as he saw duty and inclination in one, he turned all his strength in that direction. He was met upon the threshold by a common difficulty. In this world, in spite of its many agreeable features, even the most sensitive must undergo some drudgery to live. It is not possible to devote your time to study and meditation without what are quaintly but happily denominated private means; these absent, a man must contrive to earn his bread by some service to the public such as the public cares to pay him for; or, as Thoreau loved to put it, Apollo must serve Admetus. This was to Thoreau even a sourer necessity than it is to most; there was a love of freedom, a strain of the wild man, in his nature, that rebelled with violence against the yoke of custom; and he was so eager to cultivate himself and to be happy in his own society, that he could consent with difficulty even to the interruptions of friendship.
