Kamp Reverse-Sobels “Only” Suspension

I just returned from a very stimulating workshop on philosophy and linguistics at the University of Michigan. There was a lot of good discussion throughout the weekend (and much merriment to boot). One of the highlights was Sunday morning’s discussion of Michela Ippolito’s very clever paper on “only”#[1]. During that discussion, we came across what I think is a new discovery.

One of the puzzles about “only” is that the presupposition/implicature/entailment/whatever that the prejacent is true can be suspended:

Only Kim can pass the test, and maybe even she can’t.

It is striking that straightforward cancellation is impossible, but that with epistemic modal riders like “maybe” (and, as Mandy Simons noted in the discussion, the almost obligatory appearance of “even”), suspension seems possible.

Now, the cool thing was that Hans Kamp said that this felt to him to be quite similar to the famous Sobel sequences in the counterfactual literature:

If John had come to the party, it would have been fun.
But of course, if John and Bill had come to the party, it would have been a disaster.

One of the characteristics of the Sobel sequence is that it can’t be reversed:#[2]

If John and Bill had come to the party, it would have been a disaster.
??But of course, if John had come to the party, it would have been fun.

So, the new discovery about “only” is that suspension cannot be run in reverse:

??Maybe even Kim can’t pass the test, but only she can.

I suspect that this fact will play a non-negligible role in the eventual discovery of the truth about “only”.

[2]: I first learned this from Irene Heim and it plays a central role in my paper “Counterfactual in a Dynamic Sequence”. Hans said that he thought this had been part of the folklore for a while, but I am not sure about that.
