"I am always insincere, as always knowing there are other moods."
And this in the notes (of the 12 volume Concord edition edited by Edward Emerson):
"This is a harsh statement of the looseness with which a growing man should hold his beliefs of the day. In this very connection an instance can be given o how bravely sincere Mr. Emerson was. While temporarily preaching in East Lexington, he introduced into his discourse leaves from a sermon written a few years before while he was a Boston minister. In delivering it, he suddenly stopped and quietly said to his hearers, "The sentence which I have just read I do not now believe," turned the page, and went on."
