Full Idea

When we come upon a counter-instance to a generalisation we can save the putative law, by treating it as potentially analytic and claiming it as a definition. ...Thus magnetism doesn't hold for phosphorus, so we say phosphorus is not a magnetic substance.

Gist of Idea

We can save laws from counter-instances by treating the latter as analytic definitions
