Some professors go into politics. Some politicians later become professors. But is there any reason to think the rules of the two “games” should be the same?
See this article by David D. Perlmutter, in the Chronicle of Higher Education: Why Politicians Should Be More Like Professors. Perlmutter points out that President Barack Obama has sometimes been accused of being “too professorial.” But just what, asks (Professor!) Perlmutter, is wrong with that? He suggests several ways in which it might actually be good if politicians adopted a more professorial demeanor. His final suggestion is that politicians need to be more like professors in their willingness to work together to solve shared problems. “More than in any other trade, professors will sit down, work together with people with whom they hold deep ideological differences, and get the job done.” As for politicians: “It’s fine to be partisan about ideas,” he says, “but governing must be collaborative.”
By way of prescient rebuttal, see this piece by our friend (and sometime professor) Andrew Potter, writing in the Ottawa Citizen: Gangster Politics.
In a philosophical debate, what everyone involved is trying to get at is the truth. As a result, each party has a vested interest in the discussion remaining as rational and free of bias as possible. Even better, the truth is what economists call a “non-rival good” – many people can partake in the truth at the same time without anyone’s share being diminished.
In contrast, what is at stake in the political realm is not truth but power, and power (unlike truth) is a “rival good” – one person or group can wield power only at the expense of another.
Unfortunately, the very essence of politics makes partisanship inevitable….
In general, if you’re going to propose new norms for a game, it’s good to have a clear understanding of what is really at stake in that particular game, first.
Ethics for Adversaries 
Of course, what also needs to be challenged is Perlmutter’s characterization of academia itself: “More than in any other trade, professors will sit down, work together with people with whom they hold deep ideological differences, and get the job done.”
That is bullshit on rollerskates. If anything, academia is at least as adversarial an enterprise as politics; in many ways, it is far more so.
Andrew:
Absolutely, I agree. There are academics who have made entire careers out of rehashing implausible points of view, as part of an adversarial game. In the world of business, such behaviour would simply be driven out of business.
