Psychologists and neuroscientists have delivered a lot of bad news about the inner workings of our minds, raising challenging questions about the extent to which we are rational in important domains of our judgments. I will focus on a central case of an unsettling effect on our perception, and primarily aim to establish that there actually is no impact from it on the rationality of our perceptual beliefs. To reach my goal, I will start with a rough review of different (...) ways bad news about our minds might negatively affect our rationality. I’ll then propose a test for when negative consequences would follow from the truth of some bad news about our minds, and I will argue that the test is not passed in a paradigmatic case of influence of bias on perception. I will then close by looking at potential wider implications of the psychological bad news for debates about internalism vs. externalism in epistemology. (shrink)

There are many important dimensions of epistemic evaluation, one of which is justification. We don’t just evaluate beliefs for truth, reliability, accuracy, and knowledge, but also for justification. However, in the epistemological literature, there is much disagreement about the nature of justification and how it should be understood. One of the controversies that has separated the contemporary epistemological discourse into two opposing camps has to do with the internalism-externalism distinction. Whereas internalists defend certain core assumptions about justification from the pre-Gettier (...) tradition, externalists generally think that the traditional conception is untenable and should be replaced. In this compilation thesis, I argue for, defend, and develop a particular brand of internalism, both in general and with respect to specific sources of justification. In papers 1 and 2, I defend a couple of well-known arguments for mentalism and accessibilism. Moreover, I also point out how prominent versions of these theses are vulnerable to serious problems (e.g., about over-intellectualization and vicious regresses). Part of my goal in the first couple of papers is to figure out what commitments the internalist should take on in order to avoid the externalist's objections, while at the same time receiving support from considerations that have motivated internalism in the past. In papers 3 and 4, I start from the assumption that mentalism is true and attempt to answer the following questions: 1) which non-factive mental states can play a justification-conferring role with respect to empirical belief? And 2) why does this set of states play the epistemic role it does? In response to question 1, I argue that all and only one's beliefs and perceptual experiences have justificatory relevance. In response to question 2, I argue that one's beliefs and perceptual experiences are one's strongly representational states, and that strongly representational states necessarily provide support to certain empirical propositions. Having done so, I then defend mentalism about scientific evidence from a couple of prominent objections in the recent literature. Lastly, in papers 5 and 6, I argue for a particular brand of internalism about testimonial and memorial justification and show how that position has a dialectical advantage over its main competitors.

"Self-knowledge" is commonly used in philosophy to refer to knowledge of one's particular mental states, including one's beliefs, desires, and sensations. It is also sometimes used to refer to knowledge about a persisting self -- its ontological nature, identity conditions, or character traits. At least since Descartes, most philosophers have believed that self-knowledge is importantly different from knowledge of the world external to oneself, including others' thoughts. But there is little agreement about what precisely distinguishes self-knowledge from knowledge in other (...) realms. Partially because of this disagreement, philosophers have endorsed competing accounts of how we acquire self-knowledge. These accounts have important consequences for the scope of mental content, for mental ontology, and for personal identity. (shrink)

This article defends the thesis that in theorizing about the mind we need to accord first-person (“introspective” or “reflective”) judgments about experience a “selective provisional trust.” Such an approach can form part of a descriptive psychology. It is here so employed to evaluate some influential interpretations of research on attention to conclude that—despite what conventional wisdom suggests—an “introspection-positive” policy actually offers us a better critical perspective than its contrary. What supposedly teaches us the worthlessness of introspection actually shows us why (...) we need to take it seriously. (shrink)
