Single Idea 3811

[catalogued under 2. Reason / A. Nature of Reason / 1. On Reason]

Full Idea

We must distinguish between entailment and validity as logical relations on the one hand, and inferring as a voluntary human activity on the other.


The first two are part of pure logic, but 'inference' (from one idea to the next) is part of our natural rational thinking

Gist of Idea

Entailment and validity are relations, but inference is a human activity
