society. It pays through the nose and all its other senses for each staple that shapes its life. That our human senses, of which all media are extensions, are also fixed charges on our personal energies, and that they also configure the awareness and experience of each one of us, may be perceived in another connection mentioned by the psychologist C. G. Jung: Every Roman was surrounded by slaves. The slave and his psychology flooded ancient Italy, and every Roman became inwardly, and of course unwittingly, a slave. Because living con- stantly in the atmosphere of slaves, he became infected through the unconscious with their psychology. No one can shield himself from such an influence (Contributions to Analytical Psychology, London, 1928).
