More Wide-Scoping Modals
Posted by Neal on May 7, 2008
Two posts ago, I was talking about sentences like They must have loosened the pins and {he didn’t notice / him not have noticed}. Based on just examples with epistemic modals, the interim conclusion I reached was:
It looks like the pattern here is actually that the second clause must have tense, but person/number marking is optional.
Commentator Ellen K. added that she preferred the phrasing They must have loosened the pins and he not have noticed, so this is another possibility to consider. However, it is still consistent with the hypothesis that person/number marking is optional; the only detail is whether the no-person/no-number verb requires a nominative subject or not. For now, I’m going to avoid this third phrasing option, and just see what patterns there are with the phrasings I’ve been working with. The grammaticality judgments I’ll be giving are mine alone; however, my own intuitions have probably been compromised by thinking about these sentences and saying them to myself so much. I welcome your grammaticality judgments.
So, now I’ll look at some sample sentences with deontic modals, i.e. those that express obligation or permission. I’ll start with those expressing obligation, and go ahead and include the quasi-modal have to with them:
Deontic modals: requirement or obligation
- PRESENT TIME
- You must steal the medallion and {*they don’t see you / them not see you}.
- You have to steal the medallion and {?they don’t see you / them not see you}.
- You should steal the medallion and {*they don’t see you / them not see you}.
- You ought to steal the medallion and {*they don’t see you / ?them not see you}.
- PAST TIME
- You had to steal the medallion and {*they didn’t see you / them not see you}.
- You should have stolen the medallion and {*they didn’t see you / *them not see you / them not have seen you}.
- You ought to have stolen the medallion and {*they didn’t see you / ?them not see you / them not have seen you}.
With obligation deontic modals, then, it looks like the second clause again must have tense: You can see this in the past-time examples where them not see you is ungrammatical. Now, however, person/number marking is not optional; it’s forbidden. As for why the ought example sounds bad either way, I don’t know.
I’m not done with these wide-scoping modals yet. Soon I’ll look at dynamic modals (those that talk about ability or willingness), and I want to take a closer look at negations that scope over an entire coordination, too.
