David Hume was right to predict that superstition would survive for hundreds of years after his death, but how could he have anticipated that his own work would inspire Kant to invent a whole new package of superstitions? Or that the incoherent system of Marx would move vast populations to engineer their own ruin? Or that the infantile rantings of the author of Mein Kampf would be capable of bringing the whole world to war?
Perhaps we will one day succeed in immunizing our societies against such bouts of collective idiocy by establishing a social contract in which each child is systematically instructed in Humean skepticism. Such a new Emile would learn about the psychological weaknesses to which Homo sapiens is prey, and so would understand the wisdom of treating all authorities - political leaders and social role-models, academics and teachers, philosophers and prophets, poets and pop stars - as so many potential rogues and knoves, each out to exploit the universal human hunger for social status. He would therefore appreciate the necessity of doing all of his own thinking for himself. He would understand why and when to trust his neighbors. Above all, he would waste no time yearning for utopias that are incompatible with human nature.
-- Ken Binmore, in Natural Justice, p56
Science works by scientists not doing all their thinking for themselves. That's also how it fails. Getting the balance right may be hard, but no-one has really tried very hard, so it may not be. Trying to do that is largely what I see SIAI as being about.
