I give three lectures in Boston at the Masonic Temple; the first and second on Nov. 5th and 8th respectively. I should be greatly appalled in some respects, but still charmed, to have you for an auditor, seeing thus a hundred empty seats obliterated; but, I beg of you, don't let any engagement suffer by such kindness to me. Looking over the lectures again they horrify me with their loud-mouthed imbecility!--but I hope they may fall upon less hardened ears in some cases. I am sure that the thought which is in them, or rather seems to me to struggle to be in them, is worthy of all men's rapturous homage, and I will trust that a glimpse of it may somehow befall my patient auditory. The fact is that a vital truth can never be transferred from one mind to another, because life alone appreciates it. The most one can do for another is to plant some rude formula of such truths in his memory, leaving his own spiritual chemistry to set free the germ whenever the demands of his life exact it. The reason why the gods seem so powerless to the sensuous understanding, and suffer themselves to be so long defamed by our crazy theologies, is that they are life, and can consequently be revealed only to life. But life is simply the passage of idea into action; and our crazy theologies forbid ideas to come into action any further than our existing institutions warrant. Hence man leads a mere limping life, and the poor gods who are dependent upon his manliness for their true revelation and for their real knowledge, are doomed to remain forever unknown, and even denied by such solemn pedants as Mr. Atkinson and Miss Martineau. However, I shall try to convert _myself_ at least into an army of Goths and Huns, to overcome and destroy our existing sanctities, that the supernal splendours may at length become credible and even visible. Good-bye till we meet in Boston, and cultivate your goodnature according to my extensive needs. I bridge the interval before our migration of 1855 exactly for the sake of certain further passages addressed to the same correspondent, from London, in the following year. The letter is a long one and highly significant of the writer's familiar frankness, but I must keep down my examples--the first of which glances at his general sense of the men he mainly met.
