Is that really love? Isn't that the commitment? Love can come both before and after we've made the commitment. But I'm pretty convinced love won't allow itself to be tied down. We can kill it within us, but we can't really make it run where ever we want it to. It's a bit stubborn and annoying that way.
Who here hasen't at one point in your lives hated yourself for loving someone?
And seriously, highest values? Ok, sure, you value somebody very highly. But are those the highest values? Really. I bought my wife 20 long roses yesterday just because I was so much in love. What's so high and noble about that? I understand why we would like to see that as something high and noble, since that means that we label our own greed and self gratification as a noble deed.... and who wouldn't want that?
When I give my wife/slave flowers its not because I make her happy. I become happy making her happy. So I do it for myself. The logical error is removing yourself from the equation. Thinking that the goal is to make her happy. It isn't. It's only about making yourself happy and using your tools you have avaialble.
It's like "hey, I'm a rational being so my actions must be rational, and therefore my goal was to make her happy". But love isn't rational, so that screws up that line of reasoning. We just have to accept that human nature/instinct includes falling in love and making the object of our love happy. Human instinct is just another word for, what-ever-makes-us-happy.
