There are many doctrines around that try to change and mold our minds-doctrines such as relativism and secularism, to name just a couple, but this book discusses 13 more. These doctrines are rather dictatorial and don’t allow for any other views than their own. Doctrines portray to be very reliable and solid, but in fact they turn out to be floating and fleeting opinions that have no foot to stand on. They are shaky ideologies disguised as solid doctrines. It’s their disguise that lures you in. Let this book open your eyes.
