"The Moral Animal, Why We Are the Way We Are: The New Science of Evolutionary Psychology" by Robert Wright.
"A brilliant and troubling attempt to look into who we really are...Wright's book constantly goads the reader to introspection, to fresh perspectives about one's choices and place in society... A subtle and stimulating interpretation that deserves wide debate." The Boston Globe
I haven't finished reading it yet but so far it beautifully elaborates and adds to the arguments and theories Darwin presented throughout his lifetime concerning evolution. It is also very well cited. I will try to do a review once I have finished. Most likely to be very soon since I can't seem to put this one down. :-)
Anybody else reading/read this?
