No one should undertake a discussion of pornography before acknowledging the pornographies—there are at least three—and before pledging to take them on one at a time. There is a considerable gain in truth if pornography as an item in social history is treated quite separately from pornography as a psychological phenomenon (according to the usual view, symptomatic of sexual deficiency or deformity in both the producers and the consumers), and if one further distinguishes from both of these another pornography: a minor but interesting modality or convention within the arts.
