Mine isn't exactly a "nature-only" explanation: the physio/ethological data was attempting more to deal with the issue of why it's a more vivid sensory experience than, let's say, rubbing elbows. Whether between a diad of lovers or mother-child, mouth contact generates intimacy through contact, and while there is no simle physio measure of intimacy, it is often felt that the tactile nerve destiny contributes to that subjective sense of the former...regardless of the (culturally defined) relationship dynamic between the subjects of the kiss.
The act of kissing amongst homo sapiens is strongly enculturated: it has rules that vary from place to place and group to group. In a way, you could even make the case that every individual "discovers" kissing - the muscle movements, the skills required - independently...sure, they know of the *concept*, but actually doing it is a different matter entirely.
Grant - no personal insult intended, but the Useless Knowledge link lives up to its name in an entirely unintended fashion. Most explicitly there are sex manuals, pillow books, erotic poetry, and pornographic art that depict/explain
kissing which are considerably older and wider spread. Linguistically, one can find words in Sanksrit, Farsi, Putonghua, for kissing that are millenia older. What you may find with the 6th-century reference is that it was a time/space locale where romantic kissing became publicly popular (again) within a larger cultural context...in a way, a fad that persisted.
Kissing, being an idea bound-up, but sometimes liminal to, sexual expression, has oscillated as a publically acceptable activity...and like other sexual activities and social appendages related to sex, has sometimes (and in some places) between consciously omitted from collective recall and public performance because of stigma (often religiously based).
[A more common example of the same recognized/silenced process in public culture - and within the "private" domain that is nonetheless open to public criticism and scrutiny - is society's recall/recognition of prostitution. While the process is ongoing, at various times the issue has been pulled in and out of public attention as a point of shame, controversy, etc.] |
