The Sociopath Next Door  by Martha Stout This is a very interesting book about sociopathy, psychopathy and narcisism. And also about conscience and love and how all of it plays together. Highly educational. With lots of stories to shed some light on different aspects of sociopathy and what is best to do if you are connected to individuals with these tendencies. What is interesting about Martha Stout is that she says that in the western world, sociopathy is more widespread than in countries of the east. And she gives good insight about the reasons why it is so.   Here are some fair use quotes from the book:             You can buy it on Amazon or your local book store. Having knowledge from this book may be crucial for your personal development.   Kind regards,
