The brain drain from philosophy couldn’t be demonstrated better than on this BloggingHeads: Tyler is clearly the more competent philosopher, the more playful, the more far ranging…and yet, he’s an economist. Singer comes across as dull as a public monument and as silent. Also, I love Cowen’s argumentative strategies, his chess moves, pushing Singer to accept certain points, leaving them, moving other pieces, then coming back to the earlier steps to settle the checkmate. Compare this debate with the debate Cowen had with Robin Hanson, where his arguments are more tepid, confused, speculative. Cowen likes to play Devil’s Advocate with his GMU colleagues, but it’s fairly certain he’s much better when he truly disagrees with his oppenent.
