He mostly sticks to a descriptive view, and talks about why our brains work the way they do without making judgements about how they should work. The main exception is the last chapter and the epilogue, where he claims that while most inconsistencies probably don't cause major issues, we really should try to do something to overcome moral hypocrisy.

There are also a few places where he e.g. argues that psychology should spend more effort on figuring out the causes of our moral intuitions, and takes shots at critics of evolutionary psychology who attack evpsych on sloppy grounds. Both while normative, those comments are more related to science than behavior in general.
