Love to A PERSON is what most of you described."
I believe it was the Greeks who had specific words for specific types of love.
http://en.wikipedia.org/wiki/Greek_words_for_love
To put it briefly (and inject a few things from my half-forgotten RE classes):
Agape: love of things generally. So "I love DB Pro"
Eros: sexual love, sensual desire
Philia: friendship, or a generally dispassionate but virtuous love
Storge: unconditional love which may never be returned by the other party, eg. love for children, or love for the less fortunate people of the world.
Quote: "Love is watching someone die."
How nice!
For what it's worth, I think love arose because it benefitted the human race as a whole. If a couple love each other and have children, and then stay together to raise this child due to their love for each other and for the child, then that means good things for the human race generally. I could go into more detail, but my explanation involves evolution so it might not be such a good idea to voice it.
However, although I think this is why love arose in the first place, that doesn't mean that it has no value. Sex exists in nature for procreation, and the pleasure we get from it is, from nature's point of view, an addendum - but that doesn't mean that this makes non-procreative sex worthless. Similarly, just because all those hormones and brainwaves were put there for the survival of genes doesn't mean you shouldn't enjoy them.
Quote: "Love is when you care about someone deeply so that you will sacrifice anything for them, even when you feel no emotional attachment towards them."
I have felt that way towards certain people sometimes: if they had stepped out into the path of an oncoming car I would have (I think) pushed them out the way and sacrificed myself. But I'm not sure if that really was love, because the decision on my part was entirely intellectual: it was as though I had determined to do those things not because I loved those people, but only because I wanted to behave like somebody who did love those people. Of course, since it's such a personal experience it would be difficult to explain it adequately, and differentiate it from pure desire, until the person you're talking to has also experienced it.
