This thesis develops a novel framework for explaining delusions. In Chapter 1, I introduce the two fundamental challenges posed by delusions: the evidence challenge lies in explaining the flagrant ways delusions flout evidence; and the specificity challenge lies in explaining the fact that patients’ delusions are often about a few specific themes, and patients rarely have a wide range of delusional or odd beliefs. In Chapter 2, I discuss the strengths and weaknesses of current theories of delusions, which typically appeal (...) to one or both of two factors: anomalous experience and reasoning abnormality. I argue that anomalous experience can help explain the specificity of delusions, but has difficulties in addressing the evidence challenge; reasoning abnormality can help address the evidence challenge, but has difficulties in explaining the specificity of delusions. This suggests that there may be an important factor that has not been captured by current theories of delusions. To search for this missing factor, in Chapter 3, I turn to normal believing. Inspired by the literature on Cartesian clarity and phenomenal dogmatism, I develop a dual-force framework of believing, according to which beliefs can be understood as the results of the interaction between the justificatory force and causal force of evidence and the justificatory force and causal force of clear experience, in which something clearly seems to be so to the subject. This framework suggests that the missing factor may be the clear experience with its distinctive phenomenal clarity that compels assent. In Chapter 4, I return to delusions, and argue that the dualforce framework can help us to get a better grip on some personal descriptions of delusions; make progress in addressing the evidence and specificity challenges of delusions; and shed new light on the underpinnings of delusions. In the end, I conclude with some remaining questions for future study. (shrink)

In this paper, I defend the judgementalist theory of emotion against the argument from recalcitrant emotions. Judgementalism holds that a necessary condition for being in an emotional state is that an evaluative belief is formed. Recalcitrant emotions are emotions that contradict endorsed beliefs and judgements. The argument from recalcitrant emotions states that a judgementalist explanation of recalcitrant emotions results in the absurd conclusion that one would hold two contradictory beliefs. I argue that emotion involves a so-called Spinozan belief-forming process: a (...) process which automatically generates beliefs, without taking all available information into account. The generated beliefs might contradict something one already believes, as the so-called Fragmentation of Belief Hypothesis predicts. Thus the judgementalist explanation of recalcitrant emotions does not lead to an absurd conclusion and therefore the argument from recalcitrant emotions is refuted. (shrink)
