The bus-driver-in-clown-costume is a wrong-headed attempt to claim that objections to change exist solely at the level of aesthetics. So, for those who have not watched the interview, the notion is that, if you got on a bus, and the bus driver was in a clown costume, you would find it weird, and perhaps uncanny; eventually, however, you would get used to all bus drivers dressing as clowns, and would no longer notice the fact.
The problem is that this only works as an idea if change is only ever an aesthetic matter. Take, for instance, the two potential changes below:
- An Act of Parliament changes the name of the House of Commons to the Senate, and replaces all Members of Parliament with Senators. No other change to the electoral system occurs.
- An Act of Parliament abolishes democracy and allows a random dictator to rule by decress.
Now, the first is stupid, but also an aesthetic choice. One would eventually get used to it, and people yet to be born, and who would grow up with this, would find it entirely natural. Conversely, having a dictatorship would always have opponents, and people attempting to restore democracy. This is the difference between an aesthetic change and a substantial one.
The problem with DFW's arguments is that they are essentially treating every social issue as an aesthetic one (bus drivers dressing as clowns, men in long hair, orphans, whatever) regardless of whether or not they have meaningful substance.
(The question of seeing everything in aesthetic terms is a really interesting one, and explains a lot being what is wrong with modern supposedly progressive politics.)
