 This section will outline several approaches to self-knowledge. Not all deserve to be called introspective, but an understanding of introspection requires an appreciation of this diversity of approaches—some for the sake of the contrast they provide to introspection proper and some because it’s disputable whether they should be classified as introspective. These approaches are not exclusive. Surely there is more than one process by means of which we can obtain self-knowledge. Unavoidably, some of the same territory covered here is also covered, rather differently, in the entry on  self-knowledge.
