In 1838 Emerson delivered an address in the Divinity School of Harvard, which produced a gusty shower of articles, sermons, and pamphlets, and raised him without will or further act of his to the high place of the heresiarch. With admirable singleness of mind, he held modestly aloof. 'There is no scholar,' he wrote to a friend, 'less willing or less able to be a polemic. I could not give account of myself if challenged. I delight in telling what I think, but if you ask me how I dare say so, or why it is so, I am the most helpless of men,' The year before, his oration on the American Scholar had filled Carlyle with delight. It was the first clear utterance, after long decades of years, in which he had 'heard nothing but infinite jangling and jabbering, and inarticulate twittering and screeching.' Then Carlyle enjoined on his American friend for rule of life, 'Give no ear to any man's praise or censure; know that that is _not_ it; on the one side is as Heaven, if you have strength to keep silent and climb unseen; yet on the other side, yawning always at one's right hand and one's left, is the frightfullest Abyss and Pandemonium' (Dec. 8, 1837). Emerson's temperament and his whole method made the warning needless, and, as before, while 'vociferous platitude was dinning his ears on all sides,' a whole world of thought was 'silently building itself in these calm depths.' But what would those two divinities of his, Plato and Socrates, have said of a man who 'could not give an account of himself if challenged'? Assuredly not every one who saith Plato, Plato, is admitted to that ideal kingdom.
