According to legend, inscribed on walls of the temple on the sacred site of Delphi in Ancient Greece were two premier injunctions: NOTHING IN EXCESS, and KNOW THYSELF. This course will be an examination of the latter injunction in an effort to discover what self-knowledge is, why it might be valuable, and what, if any, limitations it might face. What is missing from a person lacking in self-knowledge that makes her less wise, virtuous, or competent in certain areas than others who have this capacity, and what if anything might she do to fill that gap? Historical sources as well as recent research in philosophy, experimental social psychology, and neuroscience will inform our investigation, in the course of which we will become students of our own dreams, and cultivate some meditative practices.
