Title: What lies within
Description: What Lies Within: Essays on Phenomenology, Psychology, and Self-Knowledge develops an account of cognitive phenomenology and its causal and epistemic contributions to our beliefs. It argues for an accepted, yet undefended, assumption in cognitive psychology: that there is a kind of phenomenology which determines whether or not a thought is experienced as one's own. In my first essay, I rebut a recently popular position: that there is a distinctive and non-imagistic cognitive phenomenology (hereafter 'cognitive phenomenology') which constitutes the contents of thoughts. Many philosophers suspicious of cognitive phenomenology deny that it shares characteristics with the paradigmatic cases of sensory experience. In response, I provide a set of criteria which cognitive phenomenology must meet in order to qualify as a type of phenomenology. While these criteria weaken the case for the existence of cognitive phenomenology associated with the content of mental states, they also allow for a different sort of cognitive phenomenology which prima facie warrants the ascription of introspection-based thoughts to oneself or to others.

In my next essay, I argue for the existence of this different sort of cognitive phenomenology by examining a positive symptom of schizophrenia known as 'thought insertion'. In cases of thought insertion, a schizophrenic reports introspectively experiencing a thought, but claims that it has been inserted into her mind by someone else. I use recent work in cognitive psychopathology to argue that the best explanation of thought insertion is that there is a phenomenal aspect to experiencing thoughts as inserted. Furthermore, this experience prima facie warrants ascriptions of these thoughts to someone else. My explanation also reveals that there is a phenomenology to experiencing thoughts as one's own. Likewise, this phenomenal aspect of experience prima facie warrants the self-ascription of thought. My third essay defends and supplements the model of schizophrenia put forward in my second essay. While this model is not sufficient to explain fully the positive symptoms of schizophrenia, it is adequate to account for abnormal experiences. I argue that if we supplement this model with an account of rational failures we can explain how abnormal experiences result in reports of schizophrenic experience.
