E2P42D
Demonstration — Part II
Latin
Hæc propositio per se patet. Qui enim inter verum et falsum scit distinguere, debet adæquatam veri et falsi habere ideam hoc est (per II scholium propositionis 40 hujus) verum et falsum secundo aut tertio cognitionis genere cognoscere.
English (Elwes 1883)
This proposition is self--evident. He, who knows how to distinguish between true and false, must have an adequate idea of true and false. That is (II. xl., note ii.), he must know the true and the false by the second or third kind of knowledge.
Modern English
