I like Scott Adams's "Dilbert" blog. He's not exactly Descartes, but he usually has something interesting to say...and often it's insightful, and sometimes it's even really clever or smart. That's a lot more than can be said about a lot of blogs out there.
In today's post, he does something he does every now and then: takes a position he doesn't agree with and tries to argue in favor of it. It's an extension of something (and most comedians) he does as a humorist; he asks "What if something is the opposite of what it seems?" If you can successfully do that, you usually will find something funny about almost anything in life. But of course, it's also analogous to the concept of holding two conflicting ideas in your mind at the same time...often referred to as a mark of intelligence.
Anyways, I've got it in my head that perhaps I should start doing this with public radio in general. Might come up with some interesting ideas as a result. I don't have anything to commit to the blog just yet, though...but I post this in case anyone's got suggestions.
