Single Idea 22329

[filed under theme 5. Theory of Logic / C. Ontology of Logic / 1. Ontology of Logic ]

Full Idea

In 1911 Russell held that the propositions of logic are supremely general truths about the most pervasive traits of reality, to which we have access by abstraction from non-logical propositions.

Gist of Idea

Logic is highly general truths abstracted from reality

A Reaction

Glock says the rival views were Mill's inductions, psychologism, and Frege's platonism. Wittgenstein converted Russell to a fifth view, that logic is empty tautologies. I remain resolutely attached to Russell's abstraction view.

14167 The only classes are things, predicates and relations [Russell]
18162 The propositions of logic are analytic tautologies [Wittgenstein]

10829 A sentence can't be a truth of logic if it asserts the existence of certain sets [Boolos]
10454 In first-order we can't just assert existence, and it is very hard to deny something's existence [Bach]
10253 Either logic determines objects, or objects determine logic, or they are separate [Shapiro]
14943 Maybe mathematical logic rests on information-processing [Ladyman/Ross]
15652 We can use truth instead of ontologically loaded second-order comprehension assumptions about properties [Halbach]
