Finks, Dispositions and Abilities

At the recent Bellingham conference, Ted Sider (in discussion of a paper by Kadri Vihvelin) made what I thought was a very good point about dispositions and conditionals. What follows are largely reflections on how Ted’s point affects debates about free will. I don’t think many of my conclusions here are original – what I say ends up being pretty close to what Neil Levy says in Frankfurt Finked (PDF), but perhaps the way I get there will be interestingly different. (And it is an excuse to display my Austinian tendencies in some detail.)

Consider the familiar example of the glass liked by a powerful sorcerer. The glass is a duplicate of my glass that will break if struck. But this glass won’t break if it is struck. The sorcerer will anticipate the strike and at that moment change the intrinsic structure of the glass so that it can handle being struck. Intuitively, the glass is still fragile, but it won’t break if it is struck. So the following identity is false.

Now here is Ted’s point. From the example we know that not both of the following identities can be true.

But the example alone doesn’t tell us which of the identities is false, just that one or the other is. Most of the recent literature on dispositions has focussed on the second identity as what is wrong. But once Ted raised it, it seemed to me that we should think again about the first identity.

Now I suspect that once we do that evaluation, we’ll find that we do probably want to keep the identification of fragility with the disposition to break if struck. (Perhaps we’ll want to replace ‘struck’ with something more precise.) But it really isn’t clear, and it certainly isn’t clear that every case that is apparently similar should be treated the same way.

For instance, consider a theorist who follows Ryle in thinking that a lot of mental predicates (like ‘clever’) denote the having of bundles of abilities, and these abilities are in turn to be analysed as dispositions. Thinking hard about finkish cases might well generate an interesting objection to such a theorist. Consider the following, somewhat long, case.

Alex and Cameron are school children. Alex is very good at long multiplication. Ask her to multiply any three digit numbers, and she’ll (after a short while) get the right answers for the right reasons. Alex is clever, and her cleverness is in part constituted (as philosophers might ordinarily put it) by her ability to do long multiplication. In fact this fact about her and multiplication is crucial. If she weren’t able to multiply like this, her other intellectual skills would not be sufficient for her to count as clever, though she’d still be rather smart.

Cameron is an intrinsic duplicate of Alex. But if you ask Cameron to multiply three digit (or larger) numbers she’ll get it wrong. That’s because a nearby sorcerer, who has taken a dislike to Cameron, will muddle Cameron’s brain whenever she tries to multiply three digit numbers, and ensure that she gets the wrong answers. Note that the sorcerer won’t just make Cameron say the wrong thing when answering the question. She’ll temporarily alter Cameron’s brain so she makes simple arithmetic errors along the way, like multiplying 8 by 7 and getting 54. Cameron makes no such errors when multiplying 1 or 2 digit numbers. Note also that Cameron is not right now doing multiplication, she’s playing football, so her brain is not muddled. (The sorcerer, for reasons best kept secret, always restores Cameron’s brain after he muddles it.)

All of the following sentences are true in the story. (I’ll stipulate that in context a multiplication question is large iff it involves numbers with three or more digits, and large numbers are numbers greater than 99.)

(1a) Alex is clever.
(2a) Alex is good at multiplying large numbers.
(3a) Alex is disposed to answer large multiplication questions correctly.
(4a) Alex has the ability to answer large multiplication questions correctly.
(5a) Alex can answer large multiplication questions correctly.
(6a) If Alex were asked a large multiplication question, she’d answer correctly.

What about the following?

(1c) Cameron is clever.
(2c) Cameron is good at multiplying large numbers.
(3c) Cameron is disposed to answer large multiplication questions correctly.
(4c) Cameron has the ability to answer large multiplication questions correctly.
(5c) Cameron can answer large multiplication questions correctly.
(6c) If Cameron were asked a large multiplication question, she’d answer correctly.

I’m pretty sure (1c) is true, and (6c) is false. And I think, though I’m not sure, that as we go down the list from (1c) to (6c), the claims get less plausible. If forced, I’d say that (3c) is true and (4c) is false, but I’m fairly tentative about these answers.

The upshot of all this is that I think it is a mistake to analyse (or conceptualise if like Ryle one doesn’t want to be a reductivist) cleverness in terms of dispositions or abilities. Cameron is clever, but it is far from clear that she has the dispositions or abilities that we’d ordinarily say constitute her cleverness. This is not to say that the cleverness is not connected to those dispositions or abilities. In fact the cleverness might just be the categorical basis of the dispositions and abilities. But it is not identical to them, or (as I misleadingly put it in setting out the problem) constituted by them.

  1. Mike says:

    I wonder why (6C) should be false. Suppose S asserts (6c). Now suppose midway through the calculation Cameron suffers some temporary neurological disorder, faints and never completes the multiplication. It would be strange for Smith to say ‘ah see, S was wrong about Cameron’. Wouldn’t you reply to Smith ‘No, S wasn’t wrong. He obviously meant that Cameron would give the right answer assuming, among other things, that the world doesn’t come to an end, that she does not suffer some strange neurological disorder, that she is not knocked out, that she is not thwarted by a sorcerer, etc.’ Aren’t conditions like these built into the antecedent of the subjunctive? It’s another story specifying these conditions in a non-question-begging way, but they do seem implicit.

  2. Neil says:

    As I understand it, Mike’s response is along the lines offered by Fischer. Fischer holds that in asking whether an agent is morally responsible for an action, we ask about whether the mechanism upon which she actually acted exhibited the right set of reasons-responsiveness, as Cameron’s does while she is playing football. Right now she can answer large multiplication questions correctly, so were she to refuse to try, we could hold her responsible for her refusal (assuming that she believes that she can do the math; she might not, if the sorcerer has frequently intervened in the past).

  3. Mike says:

    Maybe I misread the post. I think Brian might have meant that (6c) uttered by someone who knows the sorcerer story would be false. That seems right. My response was (6c) uttered by someone who did not know the sorcerer story would be true.

    Though I’m partial to a type of conditional analysis, I think Brian’s right that the first identity sentence is false. Fragility can be manifested by nearly any stimulus; if something breaks when light shines on it, that seems to be at least relevant to its degree of fragility. And if someone becomes angry for no reason at all, that’s relevant to their degree of irascibility. And what are the stimulus conditions for the disposition to grow old? It’s often hard to state any stimulus conditions for standard dispositions. One of the points Ryan Wasserman and I make in a paper forthcoming in Phil Quarterly is that irascibility is probably just the disposition to get angry, punkt. And fragility is probably just the disposition to break. Obviously if that’s so, the standard conditional analysis needs some help. More discussion in “A Gradable approach to dispositions” which I think is still available on Ryan’s website. The point is made on pg 9.
