Why oh why?

I'm wrestling with the neurobiology stuff within the Climate Change book. I've never quite been satisfied with the model that was in the skeletal draft, and pursuing a more detailed and robust understanding has led me to a bit of a philosophical biggie.

So, if you'll indulge me for just a moment, I'll romp about in some neurobiology, a bit of morality, a dash of sociology and some logic and philosophy, and hopefully we'll get to something that makes some sense, or something that clearly makes no sense and can be abandoned.

It all got a bit long so I've put it in another post back-dated so it doesn't take over the front page. Click here to read it. I'm afraid it's about 1500 words ... but any feedback is seriously appreciated!
