[catalogued under 5. Theory of Logic / A. Overview of Logic / 1. Overview of Logic]

Full Idea

Nowadays we think of the consequence relation itself as the primary subject of logic, and view logical truths as degenerate instances of this relation. Logical truths follow from any set of assumptions, or from no assumptions at all.

Gist of Idea

Logic studies consequence; logical truths are consequences of everything, or nothing

A Reaction

This seems exactly right; the alternative is the study of necessities, but that may not involve logic.
