From Ralph Waldo Emerson (1803–1882), American essayist, lecturer, philosopher, and poet, Essays: First Series (1842):
A friend is a person with whom I may be sincere. Before him I may think aloud. I am arrived at last in the presence of a man so real and equal, that I may drop even those undermost garments of dissimulation, courtesy, and second thought, which men never put off, and may deal with him with the simplicity and wholeness with which one chemical atom meets another.
