The Fundamentals of Critical Reading and Effective Writing. Inference is a mental process by which we reach a conclusion based on specific evidence. Inferences are the stock and trade of detectives examining clues, of doctors diagnosing diseases, and of car mechanics repairing engine problems.
The rule is valid with respect to the semantics of classical logic (as well as the semantics of many other non-classical logics), in the sense that if the premises are true (under an interpretation), then so is the conclusion. Typically, a rule of inference preserves truth, a semantic property. In many-valued logic, it preserves a general designation. But a rule of inference's action is purely syntactic, and does not need to preserve any semantic property: any function from sets of formulae to formulae counts as a rule of inference.
