Single Idea 7702

[filed under theme 19. Language / D. Propositions / 1. Propositions ]

Full Idea

The extreme ontological alternatives with respect to the metaphysics of propositions are a Fregean Platonism (his "gedanken", 'thoughts'), and a radical nominalism or inscriptionalism, as in Quine, where they are just marks related to stimuli.

Gist of Idea

The extreme views on propositions are Frege's Platonism and Quine's extreme nominalism

A Reaction

Personally I would want something between the two - that propositions are brain events of a highly abstract kind. I say that introspection reveals pre-linguistic thoughts, which are propositions. A proposition is an intentional state.

The 22 ideas from 'Ontology'

7679 Ontology is the same as the conceptual foundations of logic [Jacquette]
7678 Ontology must include the minimum requirements for our semantics [Jacquette]
7683 Logic is based either on separate objects and properties, or objects as combinations of properties [Jacquette]
7684 Reduce states-of-affairs to object-property combinations, and possible worlds to states-of-affairs [Jacquette]
7691 The actual world is a consistent combination of states, made of consistent property combinations [Jacquette]
7688 The actual world is a maximally consistent combination of actual states of affairs [Jacquette]
7695 Do proposition-structures not associated with the actual world deserve to be called worlds? [Jacquette]
7687 Existence is completeness and consistency [Jacquette]
7692 Being is maximal consistency [Jacquette]
7689 The modal logic of C.I.Lewis was only interpreted by Kripke and Hintikka in the 1960s [Jacquette]
7681 Logic describes inferences between sentences expressing possible properties of objects [Jacquette]
7682 Logic is not just about signs, because it relates to states of affairs, objects, properties and truth-values [Jacquette]
7685 An object is a predication subject, distinguished by a distinctive combination of properties [Jacquette]
7697 On Russell's analysis, the sentence "The winged horse has wings" comes out as false [Jacquette]
7701 Can a Barber shave all and only those persons who do not shave themselves? [Jacquette]
7694 We must experience the 'actual' world, which is defined by maximally consistent propositions [Jacquette]
7703 If classes can't be eliminated, and they are property combinations, then properties (universals) can't be either [Jacquette]
7699 Numbers, sets and propositions are abstract particulars; properties, qualities and relations are universals [Jacquette]
7702 The extreme views on propositions are Frege's Platonism and Quine's extreme nominalism [Jacquette]
7706 If qualia supervene on intentional states, then intentional states are explanatorily fundamental [Jacquette]
7704 Reduction of intentionality involving nonexistent objects is impossible, as reduction must be to what is actual [Jacquette]
7707 To grasp being, we must say why something exists, and why there is one world [Jacquette]
