The general pervasiveness of the conjunction of the lips amongst humans suggests
The general pervasiveness of the conjunction of the lips amongst humans suggests that something more than simple cultural idiosyncrasy may be involved, presumably on a level not immediately accessible to consciousness, a level in which the act is understood as symbolic, and analogous to, and suggestive of, and preliminary to, more intimate conjunctions. This is perhaps why certain human cultures object to the meeting of the lips in the fashion in question. For example, Gorean free women are commonly veiled in public, at least in part, presumably, that their provocative lips not be publicly exposed. Indeed, one of the things most dreaded by a Gorean free woman, particularly of high caste, is that they will be face-stripped and their lips exposed to public view, as though they might be those of a slave.
