Single Idea 11211

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

Full Idea

If a designated conclusion follows from the premisses, but the argument involves two howlers which cancel each other out, then the moral is that the path an argument takes from premisses to conclusion does matter to its logical evaluation.

Gist of Idea

If a sound conclusion comes from two errors that cancel out, the path of the argument must matter
