Consistency is the most common currency of political debate. But what is it worth, would you say? And why? Apart from obvious monomaniacs, few people are highly philosophically consistent in their thinking about politics on all levels – from high principle down to partisan practice and all points in between and/or to one side or the other, as politics slops into other areas of thought and life. I don’t just mean: everyone slips. I mean: every attractive view has major tensions. (That’s what we call them when they’re ours. When other people have them: utter contradictions! Repulsive stuff!)
So what is the value of consistency arguments in politics – bold exposures of the other side’s contradictions, bouts of tidying up of one’s own? Would you say?
It’s tempting to say that consistency is an asymptotic or regulative ideal: we approach but know we aren’t really going to get there. But that doesn’t really seem right. It doesn’t seem right that we really value consistency very highly. (See above: most consistent people seem like fanatics.) No one switches partisan sides because the other side seems to have assembled a more internally coherent match of policies and principles. It doesn’t seem as though, as people become more sophisticated, politically, they become more consistent, philosophically. Possibly this has something to do with pluralism about value. (Feel free to make reference to pluralism – or hobgoblins – in your answer.) But if pluralism means it’s ok to be inconsistent, what is the value of consistency?
I also don’t mean to imply that even the most philosophically sophisticated students of politics are as utterly, intellectually self-betraying as your average partisan idiot. Getting shot with 500 bullets is way more bullets than getting shot with 5 bullets. Still, dead is dead. I think John Rawls, for example, is a more consistent political thinker than Donald Trump. But I also think that Rawls’ political philosophy suffers from at least five fatal defects: unresolvable, fairly central contradictions (inconsistencies, tensions, call them what you will.) Does it make sense to favor a view that suffers from five fatal contradictions over a view that suffers from 500 on grounds of consistency, per se?
All the same, I really can’t feature not valuing consistency quite highly. What do you think?
