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.
