Robert really finds political labels, such as “conservative” and “liberal,” quite unhelpful.  Especially when applied to people.  Anyway, he is interested in understanding the primary themes of politics.  In that light, this seems to be a very good list of non-fiction reading if one wants to understand what “conservatives” stand for.

Robert still has not yet read Road to Serfdom.  Ugh.
