Some questions about love:
The body is wired for sex; we don't have to learn a sex drive. Is the body wired for agape? Storge? Philia? We seem to need to be taught about agape; love of country or community; philia may need less tutoring than agape, but we at least need to learn how to practice philia, agape, storge. ["Storage" only shows up in discussions like this. What word do most people use for Storge (storgē, Greek: στοργή) is liking someone through the fondness of familiarity, family members or people who relate in familiar ways that have otherwise found themselves bonded by chance. An example is the natural love and affection of a parent for their child.].
Is there a single source for the "love urge" be it for one's child, one's friend, one's brother, for 'the world', for whatever it is that we love?
How is erotic love -- or raw eros, for that matter -- related to the other types of love?
Is there 'a basic love' that differentiates in various ways, given the circumstances, or do the various kinds of love arise separately? (seems unlikely to me).
I'm not expecting any definitive answers. Lots of theories out there.
As for erotic love -- my theory is that eros begins as a raw form and is gradually tamed, civilized. Who does the taming, the civilizing? Parents? Not mine -- they didn't talk about sex. School? God, no. The church. God forbid. Who, then?
Eros gets civilized, tamed, during sexual interactions--in the trenches, as it were. Other people set the limits on what they find acceptable or out of bounds, and since we want their approval / cooperation... whatever, we conform to their standards.
In contrast, take a person who has lived a very protected life or has lived in an institution from childhood into adulthood, say, owing to disability or MI. They are liable to display inappropriate sexual behavior because they haven't been out and about enough. By "inappropriate" I mean they don't "read the room" very well.
(I'm thinking of a fellow I met at the Y who was in a MI program. He said he was schizophrenic; could well be. He apparently was gay. His behavior in the locker room wasn't scandalous, it was
unschooled. 99.9% of men avoid prolonged frank stares, for instance. Not this guy, I was sorry to see him at a large gay bar downtown later -- not the place uninitiated vulnerable people should be hanging out.). He hadn't learned the social routines of fitness centers, let alone gay bars.
Case reports aside, most people learn how to seek out and find, locate sexual partners; appraise them for suitability; determine interest, make appropriate overtures, and go somewhere to get It on. Having gotten there, we learn what works well, what falls flat, what is likely to upset or antagonize, and how to avoid doing it. (Thinking of my first early adult sexual experience, "OK, now what am I supposed to do?)
In most cases, it doesn't take long to figure all this out, because quite often the rules for sexual encounters are similar to those that apply in any other kind of encounter.
