Western philosophy has been worshipping reason and distrusting the passions for thousands of years.4 There’s a direct line running from Plato through Immanuel Kant to Lawrence Kohlberg. I’ll refer to this worshipful attitude throughout this book as the rationalist delusion. I call it a delusion because when a group of people make something sacred, the members of the cult lose the ability to think clearly about it. Morality binds and blinds.
