Single Idea 14303

[catalogued under 10. Modality / B. Possibility / 8. Conditionals / d. Non-truthfunction conditionals]

Full Idea

The utility of [truth-functional conditionals] is that it puts us in possession of a rule...[namely] The hypothetical proposition may be ...falsified by a single state of things, but only by one in which A [antecedent] is true and B [consequent] is false.

Gist of Idea

Truth-functional conditionals have a simple falsification, when A is true and B is false

A Reaction

Personally I am rather more interested in verifying conditionals than in falsifying them. I certainly don't accept them until they are falsified, unless they have massive support from surrounding facts.
