Imperviousness To Reason

From Is religion a threat to rationality and science? by Daniel Dennett and Robert Winston:

If religion isn't the greatest threat to rationality and scientific progress, what is? Perhaps alcohol, or television, or addictive video games. But although each of these scourges - mixed blessings, in fact - has the power to overwhelm our best judgment and cloud our critical faculties, religion has a feature of that none of them can boast: it doesn't just disable, it honours the disability. People are revered for their capacity to live in a dream world, to shield their minds from factual knowledge and make the major decisions of their lives by consulting voices in their heads that they call forth by rituals designed to intoxicate them.

Amen to that.
