(11/?)
Which brings me to an author whose books might contain more actionable intelligence for us than Popper's; M. Scott Peck. Peck is best known for the self-help book The Road Less Traveled (1978). But the pair of books that interest me here were published in the 1980s; People of the Lie (1983) and The Different Drum (1987).
People of the Life is all about sociopaths. How to identify and defend ourselves against them, both personally and collectively. Different Drum is about community.
