Recent Drafts

  • Lewis's Empiricism Local PDF
    Lewis's models of knowledge and belief don't allow for a priori enquiry. I like these models. But then what is going on when we do metaphysics (or maths)?
  • Objects of Choice Local PDF
    I suggest that an agent's decision-theoretic options should be construed as primitive propositions corresponding to possible outputs of her decision mechanism.
  • Evidentialism and Conservatism in Bayesian Epistemology Local PDF
    I show that in a variety of scenarios, including the Sleeping Beauty problem, there is tension between the "evidentialist" norm that one should proportion one's beliefs to the evidence and the "conservative" norm that one should only changes one's beliefs for good reasons. I argue that we should jettison the evidentialist norm.
