Jean Kazez finds recent interest in disagreement most agreeableI’ve always enjoyed the dramas of a philosophy seminar room. After a talk, somebody’s bound to become apoplectic. They’ll make objections in a great rush, with a red face, maybe even pound the table. The rest of the room will look on in suspense. For a moment, it appears the speaker’s argument has been demolished. But no, she comes back with a response, also delivered with the greatest confidence. Rebecca Goldstein hilariously describes such a scene in her new novel 36 Arguments for the Existence of God: A Work of Fiction.
I’d normally be talking about the novel in my column (my review of 36 Arguments is at kazez.blogspot.com), but for this special issue, I get to talk about a “big idea” that’s surfaced in the last decade. The idea I have in mind concerns what happens next after philosophers clash. When the talk is over, all will probably be forgiven, and perhaps one will intone that calming platitude: “reasonable people will disagree.” In essence, they will each regard the disagreement they’ve had with a wholly respected peer as no reason at all to abandon ship. Does that reaction to disagreement make sense?
I’m starting to wonder because of the literature on disagreement that’s been growing steadily in the last five years. Richard Feldman is sceptical about the possibility of mutually respectful disagreement in a seminal paper called “Reasonable Religious Disagreements” (in Philosophers without Gods, edited by Louise Antony). His point is about all “genuine” disagreements, those between people who really do disagree (they aren’t just using words in different ways, pondering a non-factual matter, or some such) and who have shared their evidence and arguments.
Let’s say Tom and I disagree about some factual matter – say, about the existence of God. Our disagreement comes down to premise T3 of his argument for theism, which seems true to him, but not to me, and premise J3 of my argument for atheism, which seems true to me, but not to him. We each consider the other intelligent, good, unbiased, well-intentioned, etc. (we are “epistemic peers,” as the literature puts it). I can’t criticise him for finding T3 plausible, and he can’t criticise me for finding J3 plausible. So we disagree in a friendly, tolerant, mutually respectful fashion. Isn’t it great?
Feldman thinks the only problem is that we’re both being irrational. If we can really find no general fault with each other, shouldn’t we take each other’s seemings just the way we would take our own? That means we each must be impressed with the evidence for both atheism and theism, so we should both suspend belief. So much for respectful disagreement. Our unalloyed mutual admiration should erase the line between us and turn us into agreeing agnostics.
This is unsettling, and not just on a personal level. If Feldman is right, there should be fewer philosophy books that argue that p, and more that argue for bland disjunctive conclusions – p or q or r….depending on how many other philosophers with different positions the author is inclined to wholly respect. Alternatively, philosophers need to find it in themselves to regard each other more negatively. That’s an odd recommendation, considering how ubiquitous disagreement is in philosophy, and because of the way philosophers tend to see themselves as being (collectively, not just individually) among the world’s most clever people. (Don’t they?)
Going more negative, I could (as Thomas Kelly suggests) see Tom as non-credible on this occasion, for the very reason that I think he has the wrong views on T3 and J3. It’s also tempting to just trust my own seemings – after all, they do represent how things seem to me. Of course, Tom could have the same critical view of me, and the same trust in himself, and that’s worrisome. Considering the symmetry, and that we can’t point to any specific, neutrally characterisable error committed by the other, it’s very tempting to think we’re required to bend, not stick to our guns.
Bending and reconsidering in the face of disagreement is certainly what people do when they’re engaged in projects like medical diagnosis or figuring out a restaurant tip or predicting the weather, as David Christensen points out. Why not when the issue is philosophical? Perhaps people handle disagreement distinctively in philosophy because it’s so incessant. Positions become identities (“I am a utilitarian”, “I am a compatibilist”), and come to be maintained with tolerance for other identities. Beliefs don’t come and go in the way they do when consensus is just around the corner.
The battle over disagreement is being waged in conferences and journals, and Feldman has just co-edited a diverse group of articles on disagreement which is being published in September. Considering all the competing views, you may think “reasonable people will disagree,” but hold on! This literature has made me think twice and three times about that attractive platitude.
