I think that what one can see from a Darwinian account is how the addition of culture in our species turns us into a very special sort of animal, an animal that can be a moral agent in a way that no other animal can be.

Some cultural phenomena bear a striking resemblance to the cells of cell biology, actively preserving themselves in their social environments, finding the nutrients they need and fending off the causes of their dissolution.

Highly technical philosophical arguments of the sort many philosophers favor are absent here. That is because I have a prior problem to deal with. I have learned that arguments, no matter how watertight, often fall on deaf ears. I am myself the author of arguments that I consider rigorous and unanswerable but that are often not such much rebutted or even dismissed as simply ignored.

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.

Cost is always an object - the second law of thermodynamics sees to that

Human freedom is not an illusion; it is an objective phenomenon, distinct from all other biological conditions and found in only one species - us.

True, you don't have to be religious to be crazy, but it helps.
