Skepticism about the A Priori and A Posteriori

Most of us have believe a host of ordinary claims—both claims about the external physical world, and about a priori domains such as logic, mathematics, and morality. Skepticism of the most interesting sort denies that we’re rational in giving more credence to these ordinary claims than to the alternative claims that figure in various skeptical hypotheses. We’ll look at some contemporary responses to skepticism. Roughly half of the course will deal with skepticism in the empirical domain, and the other half will deal with skepticism about a priori matters. This course is intended for graduate students in philosophy. Others may take the course with the instructors’ permission.
