Uriah Kriegel 
Subjective Consciousness [PDF ebook] 
A Self-Representational Theory

Some mental events are conscious, some are unconscious. What is the difference between the two? Uriah Kriegel offers the following answer: whatever else they may represent, conscious mental states always represent themselves (whereas unconscious ones do not, at least not in the right way). The book develops this ‘self-representational’ approach to consciousness along several dimensions — including phenomenological, ontological, and scientific — and defends it fromcommon and uncommon criticisms.
