history is the primitive concept that the origin of pain is purely external. Mereskey (1980) suggested that as far as we have come in the study of pain, "the ideas of Jeremiah and Aristotle still find a place in thought after more than two millennia" (p. 6). Aristotle declared pain to be one of the "passions of the soul" and separated it from the five senses, giving it an identity of its own.

Jeremiah would be considered to have believed in an external locus of control, that is attributing pain to forces outside the individual, such as fate, bad luck, or evil eye. Personality Jungian type theory postulates that "much seemingly chance variation in human behavior is not due to chance; it is in fact the logical result of a few basic observable differences in mental functioning" (Nyers, 1980, p. 4). Jung asserted that these differences were not gender specific or related to social class nor were they "mere idiosyncrasies of character peculiar to individuals" (cited in Campbell, 1976, p. 179). He believed that the apparent random distribution of type was evidence that "it cannot be a matter of conscious intention, but must be due to some unconscious instinctive cause" (cited in Campbell, 1976, p. 180). Jung's types are meant to be descriptive of normal behavior essentially free of psychopathology. Differences lie in how people perceive the world and how they judge what they perceive. The way people use these functions, perception (P) and judgment (J), is related to their
