The previous post may have been somewhat elliptical. I was trying to dra a distinction between systems of certainty & systems of contingency. Science & the arts are systems of contingency (though they have deep epistemological differences, whereas fundamentalist religions & conspiracy theories are systems of certainty. Systems of certainty are, by both definition & experience, fantasy. I was about to say that systems of certainty are infantile, but in fact most six-year-olds have a better sense of the world's uncertainty than the various peddlers of fundamentalist faith. The hatred of the quasi-Christian & quasi-Islamic fundamentalists is a function of the difficulty of maintaining a simplistic worldview. I heard an interview with the cognitive scientist Marvin Minsky on the radio this afternoon in which he noted, in passing, that when people are angry, their brains are not "looking ahead" & that brains in such states cannot perform the reflective & executive functions required for basic self-awareness. I don't agree with Minsky about the prospects for thinking computers, but anyone who has read Sophocles knows the psychological cost of anger.
