"Life is suffering" may be a Noble Truth, but it feels like a deepity. Yes, obviously life includes suffering. But it also includes happiness. Many people live good and happy lives, and even people with hard lives experience some pleasant moments.

This is the starting point of many people's objection to Buddhism. They continue: if nirvana is just a peaceful state beyond joy or suffering, it sounds like a letdown. An endless gray mist of bare okayness, like death or Britain. If your life was previously good, it's a step down. Even if your life sucked, maybe you would still prefer the heroism of high highs and low lows to eternal blah.

Against all this, many Buddhists claim to be able to reach jhana, a state described as better than sex or heroin - and they say nirvana is even better than that. Partly it's better because jhana is temporary and nirvana permanent, but it's also better on a moment-to-moment basis. So nirvana must mean something beyond bare okayness. But then why the endless insistence that life is suffering and the best you can do is make it stop?

I don't know the orthodox Buddhist answer to this question. But I got the rationalist techno-Buddhists' answer from lsusr a few months ago, and found it, uh, enlightening. He said: mental valence works like temperature.

Naively, there are two kinds of temperature: hot and cold. When an environment stops being hot, then it's neutral - "room temperature" - neither hot nor cold. After that, you can add arbitrary amounts of coldness, making it colder and colder.
