Central to Kant's ethics are the ideas of reason and universality. Central to Rawls' conception of justice is the so called original position. Interestingly enough, however, though Rawls' view may appear initially very unkantian in its focus on what self interested people would choose (Hobbesian egoism) his appeal to the veil of ignorance actually brings out an important similarity between the two views. Make a post that explains to a general reader:
1) The role of reason (as opposed to passion) in Kant's ethics and what it means to tie reason to universality;
2) What the original position is supposed to be;
3) How restricting the vantage point in the original position to one of ignorance actually brings out an important connection between the concepts of justice and the universalty of reason.
