The book contains a theory of knowledge, self-trust, autonomy, and consciousness. It takes an explanatory system, a theory, to solve philosophical problems, whatever the risk of error. The theory is a coherence theory of knowledge, a defensibility theory of knowledge. The defensibility is an internal capacity supplied by an evaluation system to defend the target claim. Defense or justification that is sustained by truth in the background system is defensible knowledge. Exemplar representation of conscious experience, exemplarization, connects the system with truth by making experience self-representational. The truth-maker and the representation of it are one. The exemplarized experiences also become exhibits of what it is like to experience external entities radiating to represent them. In this way, the accepted premises of our experience, our exemplar representations, become part of the justification and defense of target knowledge claims within our evaluation system.
