Your genes want you to reproduce successfully, they don't want to optimize for happiness. As such it may be necessary to make an extraordinary effort to acquire a decent mate, a task that goes against many of our other instincts. Such an effort is harder to do if you realize that the person in question is in fact fairly average and not The Most Perfect Person Ever. Note that some of the reasons you choose to fall in love are important yet hidden from your conscious mind, such as the importance of choosing a mate with a dissimilar major histocompatibility complex so as to produce healthier offspring. You should be careful when arrogantly rejecting the opinion of your specialized mate choice function with millions of years of evolutionary experience because you think you can make better choices in its area of expertise. Perhaps in the future we will be able to find mates that are agreeable to both our conscious and our unconscious, so that we don't get into a relationship with someone the other rejects. For example, in the future online dating sites will probably all require your DNA (which will be cheap to read) to check for genetic compatibility.
On a different note, you should be careful when you use a word that means both "hormone-induced insanity" and "a one word summary of many people's values system".
I've searched around on LW for this question, and haven't seen it brought up. Which surprises me, because I think it's an important question.
I'm honestly not sure what I think. One one hand, love clearly leads to an element of happiness when done properly. This seems to be inescapable, probably because it's encoded in our DNA or something. But on the other hand, there's two things that really make me question whether or not love is a good idea.
1) I have a very reductionist viewpoint, on everything. So I always ask myself, "What am I really trying to optimize here, and what is the best way to optimize it?". When I think about it, I come to the conclusion that I'm always trying to optimize my happiness. The answer to the question of, "why does this matter?" is always, "because it makes me happy". So then, the idea of love bothers me, because you sort of throw rational thinking out the window, stop asking why something actually matters, and just decide that this significant other intrinsically matters to you. I question whether this type of thinking is optimal, and personally, whether or not I'm even capable of it.
2) It seems so obsessive, and I question whether or not it makes sense to obsess so much over one thing. This article actually explores the brain chemicals involved in love, and suggests that the chemicals are similar to those that appear in OCD.
Finally, there's the issue of permanence. Not all love is intended to be permanent, but a lot of the time it is. How can you commit to something so permanently? This makes me think of the mind projection fallacy. Perhaps people commit it with love. They think that the object of their desire is intrinsically desirable, when in fact it is the properties of this object that make it desirable. These properties are far from permanent (I'd go as far as to say that they're volatile, at least if you take the long view). So how does it make sense to commit to something so permanently?
So my take is that there is probably a form of love that is rational to take. Something along the lines of enjoying each others company, and caring for one another and stuff, but not being blindly committed to one another, and being honest about the fact that you wouldn't do anything for one another, and will in fact probably grow apart at some point.
What do you guys think?
