It is prima facie highly implausible that life as we know it is the result of a sequence of physical accidents together with the mechanism of natural selection. We are supposed to abandon this naรฏve response, not in favor of a fully worked out physical/chemical explanation but in favor of an alternative that is really a schema for explanation, supported by some examples. What is lacking, to my knowledge, is a credible argument that the story has a nonnegligible probability of being true.
Thomas NagelIf we tried to rely entirely on reason, and pressed it hard, our lives and beliefs would collapse - a form of madness that may actually occur if the inertial force of taking the world and life for granted is somehow lost. If we lose our grip on that, reason will not give it back to us.

Thomas Nagelfundamentally an organism has conscious mental states if and only if there is something that it is like to be that organism--something it is like for the organism.
Thomas NagelThe point is... to live one's life in the full complexity of what one is, which is something much darker, more contradictory, more of a maelstrom of impulses and passions, of cruelty, ecstacy, and madness, than is apparent to the civilized being who glides on the surface and fits smoothly into the world.
