The exposition of a text exposes its meaning and its underlying mechanism. Exposure removes a covering, it reveals, it makes visible. To expose a deceit or a fraud is to tacitly censure its perpetrator. To expose what, in a given situation, is out of place or contrary to propriety is to censure either the person so exposed or those whose actions are responsible for the situation so exposed. Exposure is neutral or even positive when it simply uncovers the mechanism by which an effect is created or a state of affairs has come to be.
