“I’ve been carrying the corpus of my grandfather — to change the famous saying—with me all my life. I was given very early two volumes of his sermons; and I never go anywhere without them. … He actually took his parish out of the Unitarian Church. As he put it, “They have defrocked not only me, but my church.” For thirty years he and the church, the New Bedford parish, were in the wilderness. Then the Unitarians, about 1890, caught up with him and embraced him. By this time he was president of the Free Religious Association and was lecturing all over the country on the necessity for a religion without dogma.
And this inheritance has been my guiding light: I regard myself simply as a continuance of my grandfather, and primarily, therefore, as a teacher and preacher, and a distributor, in poetic terms, of the news of the world, by which I mean new knowledge. This is gone into at some length in Ushant. And elsewhere I have said repeatedly that as poetry is the highest speech of man, it can not only accept and contain, but in the end express best everything in the world, or in himself, that he discovers. It will absorb and transmute, as it always has done, and glorify, all that we can know. This has always been, and always will be, poetry’s office.”
