This passage is noteworthy as showing how early the philosophic mind was developed in Thoreau, and how much his thought and expression were influenced by Emerson's first book,—"Nature." But the soil in which that germinating seed fell was naturally prepared to receive it; and the wide diversity between the master and the disciple soon began to appear. In 1863, reviewing Thoreau's work, Emerson said, "That oaken strength which I noted whenever he walked or worked, or surveyed wood-lots,—the same unhesitating hand with which a field-laborer accosts a piece of work which I should shun as a waste of strength, Henry shows in his literary task. He has muscle, and ventures on and performs feats which I am forced to decline. In reading him I find the same thoughts, the same spirit that is in me; but he takes a step beyond, and illustrates by excellent images that which I should have conveyed in a sleepy generalization." True as this is, it omits one point of difference only too well known to Emerson,—the controversial turn of Thoreau's mind, in which he was so unlike Emerson and Alcott, and which must have given to his youthful utterances in company the air of something requiring an apology.

This, at all events, seems to have been the feeling of Helen Thoreau,[7] whose pride in her brother was such that she did not wish to see him misunderstood. A pleasing indication of both these traits is seen in the first extant letter of Thoreau to this sister. I have this in an autograph copy made by Mr. Emerson, when he was preparing the letters for partial publication, soon after Henry's death. For some reason he did not insert it in his volume; but it quite deserves to be printed, as indicating the period when it was clear to Thoreau that he must think for himself, whatever those around him might think.

TO HELEN THOREAU (AT TAUNTON).

Concord, October 27, 1837.

Dear Helen,—Please you, let the defendant say a few words in defense of his long silence. You know we have hardly done our own deeds, thought our own thoughts, or lived our own lives hitherto. For a man to act himself, he must be perfectly free; otherwise he is in danger of losing all sense of responsibility or of self-respect. Now when such a state of things exists, that the sacred opinions one advances in argument are apologized for by his friends, before his face, lest his hearers receive a wrong impression of the man,—when such gross injustice is of frequent occurrence, where shall we look, and not look in vain, for men, deeds, thoughts? As well apologize for the grape that it is sour, or the thunder that it is noisy, or the lightning that it tarries not.

Further, letter-writing too often degenerates into a communicating of facts, and not of truths; of other men's deeds and not our thoughts. What are the convulsions of a planet, compared with the emotions of the soul? or the rising of a thousand suns, if that is not enlightened by a ray?

Your affectionate brother,
Henry.

It is presumed the tender sister did not need a second lesson; and equally that Henry did not see fit always to write such letters as he praised above,—for he was quite ready to give his correspondents facts, no less than thoughts, especially in his family letters.

Next to this epistle, chronologically, comes one in the conventional dialect of the American Indian, as handed down by travelers and romancers, by Jefferson, Chateaubriand, Lewis, Clarke, and Fenimore Cooper. John Thoreau, Henry's brother, was born in 1815 and died January 11, 1842. He was teaching at Taunton in 1837.
