This was partly because, in the course of writing his first book,
Peterson studied a great deal of history, mythology, psychology, and literature (the Bible, Milton’s
Paradise Lost, Goethe’s
Faust, and Dante’s
Inferno), among other subjects. He’d done all this in an effort to understand the nuclear standoff during the Cold War: why were people willing to risk the world’s destruction in order to protect their belief systems? He realized that belief systems allow people to understand one another, and that those systems are about more than just belief.
