5. Theory of Logic / C. Ontology of Logic / 1. Ontology of Logic

18162	The propositions of logic are analytic tautologies [Wittgenstein]
	Full Idea: The propositions of logic are tautologies. Therefore the propositions of logic say nothing. (They are the analytic propositions).
	From: Ludwig Wittgenstein (Tractatus Logico-Philosophicus [1921], 6.1)

5. Theory of Logic / C. Ontology of Logic / 2. Platonism in Logic

7537	Wittgenstein convinced Russell that logic is tautologies, not Platonic forms [Wittgenstein, by Monk]
	Full Idea: Russell took a Platonist view of logic, but reading the 'Tractatus' convinced him that logic was purely linguistic, so-called 'logical truths' being nothing more than tautologies.
	From: report of Ludwig Wittgenstein (Tractatus Logico-Philosophicus [1921]) by Ray Monk - Bertrand Russell: Spirit of Solitude Ch.1
	A reaction: If p-and-q and p-or-q are both tautologies, how do you explain the difference between them? The first is an indicative proposition about the actual world, but the second is modal. They are asserting very different things.
