Intercourse
Bloomfield.
Intercourse is after all man’s best teacher. “Know thyself” is an excellent maxim; but even self-knowledge cannot be perfected in closets and cloisters—nor amid lake scenery, and on the sunny side of the mountains. Men who seldom mix with their fellow-creatures are almost sure to be one-sided—the victims of fixed ideas, that sometimes lead to insanity.
