I had a 15 minute slice of clear thinking last week. I left work early enough to listen to Rush Limbaugh's show. I'm not a huge fan of conservative radio--as long as the topic is limited government or fiscal matters, it's OK. But that day was a great day. Rush was on vacation and who should be filling in? Walter Williams! I like his economics and self-sufficiency views very much. Now, Walter Williams fills in for Rush regularly, so why should this be particularly exciting? Of course, because he was interviewing Thomas Sowell! Their opinions are well-reasoned, thorough and they make it so easy to understand.
