Abstract
From a phenomenological perspective, skin is an important boundary. My model here is the psychology of interpersonal relations . It is the behaviour of O that is visible from the perspective of P, the perceiver. Whether or not one is justified in going beyond the evidence available is a matter of some controversy in psychological circles e.g. between behaviourists and gestalt psychologists . Here the skin is an important boundary, at least in the visual modality. The divergence in perspective between actor and observer is due to the fact that they occupy two different points in space/time . There is less of a divergence in perspective between speaker and listener since they could both be one and the same person . Skinner , in a pun on his own name, observed that in speech skin is not at all an important boundary. The implications for social psychology of this asymmetry between vision and speech are explored more fully . An attempt is made to identify when the skin is and when it is not a significant boundary. The history of psychology is briefly reviewed in the light of this distinction
