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.......The better is enemy of the best: religion may make many people better, but it is preventing them from being as good as they could be. If only we could transfer all that respect, loyalty and intense devotion from an imaginary being - God - to something real: the wonderful world of goodness we and our ancestors have made, and of which we are now the stewards.
