Yes, linguistics is one of those tricky subjects. It's constantly in flux. However, I hold the opinion that the more precise a language is the better. The flip side of that, though, is that a language with exact precision would be impossibly complex.
But anyway, bringing it back the issue of love. If I say, "You should marry for love," what does that mean? The implied meaning is that when you have a strong hormonal response to someone, you should marry them. But at the same time it could mean so many other things. And while the idea of marrying for love is a good one. What kind of love becomes the problem. I would argue that hormonal reaction is probably the worst basis for a marriage. What happens when the hormonal reaction is gone? It's something that is outside of one's control, so why base a marriage on it?
But then if I said, "You should marry for the kind of love that is chosen and within your control." Then the sentence becomes overly long. Whereas if I said, "You should marry for agape," the sentence maintains its brevity and precision of meaning.
So what does "love instructor" even mean? Using current english it could mean:
An instructor of profoundly tender, passionate affection.
An instructor of the feeling of warm personal attachment or deep affection.
An instructor of sexual passion or desire.
An instructor of how to interact with the person toward whom love is felt.
An instructor in how to have a love affair or an intensely amorous incident.
An instructor in sexual intercourse.
An instructor in affectionate concern for the well-being of others
An instructor of strong predilection, enthusiasm, or liking for anything.
An instructor the benevolent affection of God for His creatures, or the reverent affection due from them to God.(That's put a whole new spin on that character).
An instructor of how to score zero in tennis.
So, as I know you're aware, we just make assumptions about what love means based on context rather than having a precise meaning. So when there is no context we can just assign whatever meaning we think fits. In regards to our society I think this causes a lot of problems especially in regard to marriage.
However, in regards to a "love instructor," I'm personally leaning towards the tennis thing.
Mr. Laser beam said:
I guess I don't really have a problem with the concept of "marriage contracts". It may sound unromantic, but hell, we already have prenuptial agreements, this is just another example of those. Besides, if the couple really love each other, they can always keep renewing!
We must then ask ourselves if marriage is not possible without state involvement? If it is not then what about all those people who have been marrying each other for thousands of years without governments. So now we have to define, state sanctioned marriage and non-state sanctioned marriage. What about people who don't marry for love but marry for resources as was common in the middle ages. Now there's another layer. I guess the point I keep talking around that nobody probably cares about is this:
Marriage and love are not as simple as we are lead to believe. Trying to move forward with our erroneous notions of love and marriage is going to do more harm than good.
Trying to figure out this "love instructor" business without being able to examine our own cultural biases is going to lead to convoluted theories.
Let's just accept that, in ten years or so, we will either have or be love instructors. (which is good because I get too high of scores in Tennis.)
