Supplement to “symmetric Propositions and Logical Quantifiers”

This document contains propositions, proofs, and supplementary discussion supporting claims made in the paper “Symmetric propositions and logical quantifiers,” Journal of philosophical logic, forthcoming (henceforth SPLQ). Unless explicitly mentioned otherwise, all references are internal. Section, but not subsection, headings correspond to those of SPLQ. (The latter has no subsections.)

Presuppositions , Truth Values , and Expressing Propositions ∗

Philosophers like to talk about propositions. There are many reasons for this. Perhaps the most common is that philosophers are sometimes more interested in the content of a thought or utterance than in the particular sentence or utterance that might express it on some occasion. Propositions are offered as these contents. Like many philosophical notions, this one has been the subject of extensi...

Betting on Fuzzy and Many-valued Propositions

In a 1968 article, ‘Probability Measures of Fuzzy Events’, Lotfi Zadeh proposed accounts of absolute and conditional probability for fuzzy sets (Zadeh, 1968). Where P is an ordinary (“classical”) probability measure defined on a σ-field of Borel subsets of a space X, and μA is a fuzzy membership function defined on X, i.e. a function taking values in the interval [0, 1], the probability of the ...

A Puzzle about Truth and Singular Propositions 1 1 . Singular Propositions

My dissertation consists of three essays in the Metaphysics of Modality: In "A Puzzle about Truth and Singular Propositions," I consider two theses that seem to be true and then an argument for the conclusion that they form an inconsistent pair. One thesis is that a proposition that is singular with respect to a given object implies that the object exists. This is so because the proposition pre...
