After settling in Concord, Emerson delivered courses of Lectures in Boston during several successive winters; in 1835, ten Lectures on English Literature; in 1836, twelve Lectures on the Philosophy of History; in 1837, ten Lectures on Human Culture. Some of these lectures may have appeared in print under their original titles; all of them probably contributed to the Essays and Discourses which we find in his published volumes.
On the 19th of April, 1836, a meeting was held to celebrate the completion of the monument raised in commemoration of the Concord Fight. For this occasion Emerson wrote the hymn made ever memorable by the lines:--
Here once the embattled farmers stood, And fired the shot heard round the world.
The last line of this hymn quickens the heartbeats of every American, and the whole hymn is admirable in thought and expression. Until the autumn of 1838, Emerson preached twice on Sundays to the church at East Lexington, which desired him to become its pastor. Mr. Cooke says that when a lady of the society was asked why they did not settle a friend of Emerson's whom he had urged them to invite to their pulpit, she replied: "We are a very simple people, and can understand no one but Mr. Emerson." He said of himself: "My pulpit is the Lyceum platform." Knowing that he made his Sermons contribute to his Lectures, we need not mourn over their not being reported.
In March, 1837, Emerson delivered in Boston a Lecture on War, afterwards published in Miss Peabody's "Aesthetic Papers." He recognizes war as one of the temporary necessities of a developing civilization, to disappear with the advance of mankind:--
"At a certain stage of his progress the man fights, if he be of a sound body and mind. At a certain high stage he makes no offensive demonstration, but is alert to repel injury, and of an unconquerable heart. At a still higher stage he comes into the region of holiness; passion has passed away from him; his warlike nature is all converted into an active medicinal principle; he sacrifices himself, and accepts with alacrity wearisome tasks of denial and charity; but being attacked, he bears it, and turns the other cheek, as one engaged, throughout his being, no longer to the service of an individual, but to the common good of all men."
