I have never been sure how much I do want to know myself. Dr. Dalrymple went to a neurosciences conference, and wrote a nifty report. One quote:
It will not have escaped the notice of the observant that Marxism and Freudianism have become a little frayed around the edges of late, and that their adherents are reduced to recalcitrant membership of increasingly beleaguered sects. But the attraction of all-embracing worldviews that explain not only who we are but prescribe how we ought to live remains as strong as ever. Some of the neuroscientists to whom I listened at the conference implied that we were on the verge of such a breakthrough in our self-understanding, thanks to neuroimaging, neurochemistry and neurogenetics and so forth, that Man, proud Man, will no longer be a mystery to himself. The heart of all our mysteries will be plucked out wholesale, as it were; and to understand all will then be not so much to forgive all as to control all, especially our bad habits.
