| 4730 | For Aristotle, the subject-predicate structure of Greek reflected a substance-accident structure of reality [Aristotle, by O'Grady] |
| Full Idea: Aristotle apparently believed that the subject-predicate structure of Greek reflected the substance-accident nature of reality. | |
| From: report of Aristotle (works [c.330 BCE]) by Paul O'Grady - Relativism Ch.4 | |
| A reaction: We need not assume that Aristotle is wrong. It is a chicken-and-egg. There is something obvious about subject-predicate language, if one assumes that unified objects are part of nature, and not just conventional. |
| 15525 | Plural quantification lacks a complete axiom system [Lewis] |
| Full Idea: There is an irremediable lack of a complete axiom system for plural quantification. | |
| From: David Lewis (Parts of Classes [1991], 4.7) |
| 15518 | I like plural quantification, but am not convinced of its connection with second-order logic [Lewis] |
| Full Idea: I agree fully with Boolos on substantive questions about plural quantification, though I would make less than he does of the connection with second-order logic. | |
| From: David Lewis (Parts of Classes [1991], 3.2 n2) | |
| A reaction: Deep matters, but my inclination is to agree with Lewis, as I have never been able to see why talk of plural quantification led straight on to second-order logic. A plural is just some objects, not some higher-order entity. |
