Single Idea 17079

[catalogued under 10. Modality / D. Knowledge of Modality / 1. A Priori Necessary]

Full Idea

The fundamental proof of necessary truths comes from the understanding alone, and other truths come from experience or from observations of the senses. Our mind is capable of knowing truths of both sorts, but it is the source of the former.

Gist of Idea

Proofs of necessity come from the understanding, where they have their source

A Reaction

Interesting because it not only spells out that necessary truths are known a priori, but also explicitly says that the understanding is the 'source' of the truths, or at least the source of their proofs. He also says possibilities derive from essences.
