Reciprocity refers in its general meaning to a mutual give and take. It is a background feature of all productive supervisory relationships. In this essay I want to bring it into the foreground. I will describe it by contrasting supervision and analysis. For, in my view, that is exactly what reciprocity is in the supervisory relationship: it is an attitude of mind in which the supervisor performs the task of differentiating internally the supervisory from the analytic vertex, in the context of the asymmetry of the supervisory relationship.
