Single Idea 19000

[catalogued under 14. Science / C. Induction / 5. Paradoxes of Induction / b. Raven paradox]

Full Idea

'All ravens are black' might profitably be read as saying not that being a raven 'implies' being black, but rather something more like 'Consider the ravens: each one is black'.

Gist of Idea

Read 'all ravens are black' as about ravens, not as about an implication

A Reaction

Belnap is more interested in the logic than in the paradox of confirmation, since he evidently thinks that universal generalisations should not be read as implications. I like Belnap's suggestion.
