io <strong>Only</strong> <strong>and</strong> <strong>the</strong> <strong>Dynamics</strong> <strong>of</strong> <strong>Vertical</strong> <strong>Inference</strong><br />
As recognized by Barwise & Cooper (1981: 193), quantifiers with <strong>the</strong> same<br />
monotonicity orientation combine with <strong>and</strong>, excluding but, as seen in (21),<br />
(21) a man <strong>and</strong> three women few violins <strong>and</strong> no cellos<br />
some students <strong>and</strong> every pr<strong>of</strong>essor no men <strong>and</strong> very few women<br />
most men <strong>and</strong> any FC women no dogs <strong>and</strong> hardly any NP i cats<br />
while monotonicity-discordant quantifiers most combine with but:<br />
(20) John {# <strong>and</strong>/but] no woman<br />
few women {# <strong>and</strong>/but) many men<br />
most <strong>of</strong> <strong>the</strong> dogs {# <strong>and</strong>/but) few <strong>of</strong> <strong>the</strong> cats<br />
(vs. most <strong>of</strong> <strong>the</strong> dogs [<strong>and</strong>/#but] a few <strong>of</strong> <strong>the</strong> cats<br />
Crucially, only phrases pattern as downward monotonic quantifiers:<br />
(23) many men {# <strong>and</strong>/but) only 3 women<br />
no men {<strong>and</strong>/#but} only 3 women<br />
4 CONVERSION AND EXISTENTIAL IMPORT<br />
But in fact only phrases must be downward monotonic, given <strong>the</strong> converse<br />
relation between only <strong>and</strong> all, recognized since <strong>the</strong> medievals:<br />
(24) a. Tantum animal est homo convertitur in istam: omnis homo est animal, per<br />
istam regulam: Exclusiva affirmativa convertitur in universalem P<br />
(John <strong>of</strong> Holl<strong>and</strong>, in Bos 1985: 27)<br />
b. only (A, B) (only As are Bs) « all Bs are As ~ B c A<br />
The interdefinability <strong>of</strong> exclusives <strong>and</strong> universals appears in a variety <strong>of</strong> traditional<br />
sources, e.g. Peter <strong>of</strong> Spain's Tactatus Exponibilium (Mullally 1945: 106-7),<br />
<strong>and</strong> is exploited, defended, or assumed—<strong>of</strong>ten in <strong>the</strong> form <strong>of</strong> <strong>the</strong> subset relation<br />
in (24b))—by a bevy <strong>of</strong> moderns, including Lobner (1987), Chierchia &<br />
McConnell-Ginet (1990: 427), de Mey (1991), Johnson-Laird & Byrne (1991:<br />
128), Higginbotham (1994: 459-63), <strong>and</strong> von Fintel (1994, 1995), enough <strong>of</strong> a<br />
quorum to challenge <strong>the</strong> assertion that '<strong>the</strong>se days, those who adopt this analysis<br />
are few <strong>and</strong> far between' (von Fintel 1994: 13 5).<br />
Given this convertibility, to say that only Democrats supported Clinton is to<br />
say that all Clinton-supporters were Democrats. But, as has been recognized for<br />
a couple <strong>of</strong> millennia (cf. Horn 1989: Section 1.1.3 for summary <strong>and</strong> Moravcsik<br />
1991 for a new look), <strong>the</strong>re is an existential inference, generally assumed to hold<br />
in <strong>the</strong> pragmatics, that is characteristically associated with <strong>the</strong> assertion <strong>of</strong> a<br />
universal. 14 Thus we can infer that (for all <strong>the</strong> speaker knows) <strong>the</strong>re were indeed<br />
Clinton-supporters; o<strong>the</strong>rwise <strong>the</strong> ^//-statement would be too uninformative<br />
to assert. 15<br />
