forum for week of 12 September

One person in class on Thurs had asked whether a rational belief can be unjustified... and then did Prof Morton use the easy-to-see example of a trial (DNA, hair...) to explain that the answer is Yes, a rational belief can be unjustified? Without that example, it seems hard to see that a rational belief can be unjustified... Out of interest and fun, has anyone thought of another easy to see example where a rational belief is unjustified? Jessica chen
