[Postscript of a letter to Rev. M. B. G. Eddy.]
You have doubtless read Darwin's last book, on the Law of Roots. To us, who are learning to read symbols, it teaches that when Truth strikes its root down, and meets a solid rock of materialistic thought or intellectualism, like that of the Atlantic Coast (where we were born, for we lived in America and Europe for more than forty years till we came to the Pacific Coast) it turns,—say westward, in the sun's course,—and may seem to fix itself in soil like that of Chicago; but, however the side roots may fix and grow strong in time, the main taproot goes straight on, seeking the open, free-soil growth of a place like California,— a mental soil without binding creeds or petrifactions in it. Between the world's parent continents, Father Europe and Mother Asia, Truth strikes deep into the very foundation of the world-mind.
You can understand what we try to say, better than our words can express it, for the law is that "the greater comprehends the less."
