Yet today there are still people who think that anyone who disagrees with them must be either bad or not know what he is talking about…Students can graduate from even the most prestigious colleges and universities wholly unaware that there are not simply different opinions about particular issues but a whole comprehensive framework of ideas and analysis through which those issues can be seen in a way that leads to very different conclusions from the ones their professors have taught or insinuated…It is a shame that ancient history is seldom taught in our schools.
