There’s simply no polite way to tell people they’ve dedicated their lives to an illusion.

If the history of resistance to Darwinian thinking is a good measure, we can expect that long into the future, long after every triumph of human thought has been matched or surpassed by 'mere machines,' there will still be thinkers who insist that the human mind works in mysterious ways that no science can comprehend.

While we tend to conceive of the operations of the mind as unified and transparent, they're actually chaotic and opaque. There's no invisible boss in the brain, no central meaner, no unitary self in command of our activities and utterances. There's no internal spectator of a Cartesian theater in our heads to applaud the march of consciousness across its stage.

The traditional view of purpose says it comes from on high, from God, from the Creator. Darwin's idea of natural selection makes people uncomfortable because it reverses the direction of tradition. Whereas people used to think of meaning coming from on high and being ordained from the top down, now we have Darwin saying, "No, all of this design can happen, all of this purpose can emerge from the bottom up without any direction at all."

... there could be talking bunny rabbits, spiders who write English messages in their webs, and for that matter, melancholy choo-choo trains. There could be, I suppose, but there aren't-so my theory doesn't have to explain them.

The theoretical fruits of deliberate oversimplification through idealization are not to be denied... Reality in all its messy particularity is too complicated to theorize about, taken straight. The issue is, rather (since every idealization is a strategic choice), which idealizations might really shed some light... which will just land us... diverting fairy tales.

If I were to give a prize for the single best idea anybody ever had, I'd give it to Darwin for the idea of natural selection - ahead of Newton, ahead of Einstein - because his idea unites the two most disparate features of our universe: the world of purposeless, meaningless matter and motion, particles jostling on the one side, and the world of meaning and purpose, design on the other.
