Blind faith, no matter how passionately expressed, will not suffice. Science for its part will test relentlessly every assumption about the human condition.
[P]rescientific people... could never guess the nature of physical reality beyond the tiny sphere attainable by unaided common sense. Nothing else ever worked, no exercise from myth, revelation, art, trance, or any other conceivable means; and notwithstanding the emotional satisfaction it gives, mysticism, the strongest prescientific probe in the unknown, has yielded zero.
By any reasonable measure of achievement, the faith of the Enlightenment thinkers in science was justified. Today the greatest divide within humanity is not between races, or religions, or even, as is widely believed, between the literate and illiterate. It is the chasm that separates scientific from prescientific cultures.
[T]he true natural sciences lock together in theory and evidence to form the ineradicable technical base of modern civilization. The pseudosciences satisfy personal psychological needs... but lack the ideas or the means to contribute to the technical base.
The brain and its satellite glands have now been probed to the point where no particular site remains that can reasonably be supposed to harbour a nonphysical mind.
No statistical proofs exist that prayer reduces illness and mortality, except perhaps through a psychogenic enhancement of the immune system; if it were otherwise the whole world would pray continuously.
[W]hen the martyr's righteous forebrain is exploded by the executioner's bullet and his mind disintegrates, what then? Can we safely assume that all those millions of neural circuits will be reconstituted in an immaterial state, so the conscious mind carries on?
In fact, nothing in science as a whole has been more firmly established by interwoven factual information, or more illuminating than the universal occurrence of biological evolution. Further, few natural processes have been more convincingly explained than evolution by the theory of natural selection, or as it has been popularly called, Darwinism.
Theology made no provision for evolution. The biblical authors had missed the most important revelation of all! Could it be that they were not really privy to the thoughts of God?
Every major religion today is a winner in the Darwinian struggle waged among cultures, and none ever flourished by tolerating its rivals.
The human mind evolved to believe in the gods. It did not evolve to believe in biology.
Old beliefs die hard even when demonstrably false.
