[catalogued under 5. Theory of Logic / K. Features of Logics / 2. Consistency]

Full Idea

The difference between the principle of consistency and the principle of non-contradiction is that the former must be stated in a semantic metalanguage, whereas the latter is a thesis of logical systems.

Gist of Idea

Consistency is semantic, but non-contradiction is syntactic
