“The evolution of complex life, its very existence in a universe obeying physical laws is wonderfully surprising, or would be, up for the fact that surprise is an emotion that can exist only in a brain which is the product of that very surprising process. Our existence is desperately surprising. Natural selection produces living organisms which are entities of gigantic but not infinite probability. On one planet, and possibly only one planet in the entire universe, molecules which would normally would made nothing more complicated than a chunk of rock, have some how manage to gather them selves together into chunks of rock size matter, capable in some cases of thinking and feeling and falling in love yet other chunks of complex matter. What we see of the real world, in a sense is not the unvarnished real world, but a model of the real world regulated and adjusted by sense data, but constructed so is useful for dealing with real world. The nature of the model in our head depends of the kind of animal we are.” Richard Dawkins
