The Righteous Mind
Why Good People Are Divided by Politics and Religion
by Jonathan Haidt
A book to read and re-read. Haidt writes with clarity and thoroughness. Whether you agree or disagree his conclusions you can see in the data from where he is coming.
In the final section, he outlines our present political landscape and the steps he believes are necessary for change. However, you cannot simply cut to the QED in the last part — there is a mountain of well-crafted information and prose that must be thoughtfully climbed first.
