Single Idea 19060

[from 'The Justification of Deduction' by Michael Dummett, in 4. Formal Logic / B. Propositional Logic PL / 3. Truth Tables ]

Full Idea

It is arguable whether two-valued truth tables give correct meanings for certain sentential operators, and even whether they constitute legitimate explanations of any possible sentential operators.

Gist of Idea

Truth-tables are dubious in some cases, and may be a bad way to explain connective meaning

A Reaction

See 'Many-valued logic' for examples of non-binary truth tables. Presumably logicians should aspire to make their semantics precise, as well as their syntax.
