Single Idea 21389

[catalogued under 10. Modality / A. Necessity / 3. Types of Necessity]

Full Idea

From 'E will take place is true' it follows that E must take place. But 'must' here is logical not causal necessity. It is a considerable achievement of Carneades to have distinguished these two senses of necessity.

Gist of Idea

Carneades distinguished logical from causal necessity, when talking of future events

A Reaction

Personally I am inclined to think 'necessity' is univocal, and does not have two senses. What Carneades has nicely done is distinguish the two different grounds for the necessities.
