“Sullivan became increasingly convinced, the individual is simply not the unit to study. Human beings are inseparable, always and inevitably, from their interpersonal field. The individual’s personality takes shape in an environment composed of other people. The individual is in continual interaction with other people. The personality or self is not something that resides “inside” the individual, but rather something that appears in interactions with others. “Personality . . . is made manifest in interpersonal situations and not otherwise” (1938, p. 32), Sullivan suggested. Personality is “the relatively enduring pattern of recurrent interpersonal situations which characterize a human life” (1940, p. xi).”
