Not reading related, but I would argue that our brains in toto function as imperfect universal Turing machines ( http://en.wikipedia.org/wik... )—hence our ability to predict the responses of others. To do so, we must simultaneously hold a (flawed and incomplete) copy of another human Turing machine and the stimulus to be responded to—i.e., the arbitrary input—in our minds.
The perfect design of an eye or the flawless profile of a wing may perhaps be the work of divine genius—but what malicious divinity would have chosen to place one eye of a flatfish facing the ground, thus forcing it to migrate around the head during development?
Synesthetes also have talents that cannot be faked. The average person has trouble finding a hidden digit 2 in a sea of 5s because their shapes are very similar, but digit-color synesthetes see it immediately because the two digits appear in different colours.
