[catalogued under 5. Theory of Logic / A. Overview of Logic / 3. Value of Logic]

Full Idea

The rules of deduction are rules of entailment, not rules of inference. They tell us what follows from what, not what to believe on the basis of what.


'Entailments' are the logical relationships between statements

Gist of Idea

Deduction shows entailments, not what to believe
