Spinoza's Ethics: II.P34: Adequate Idea is True

Every idea which is absolute or adequate and perfect in us is true.

Omnis idea quæ in nobis est absoluta sive adæquata et perfecta, vera est.

When we say that an idea is adequate and perfect in us, we say nothing other (by IIP11C) than that which is in God insofar as it constitutes the essence of our mind, let it be given that the idea is adequate and perfect and consequently (by IIP32) we say nothing other than that such idea is true.

DEMONSTRATIO: Cum dicimus dari in nobis ideam adæquatam et perfectam, nihil aliud dicimus (per corollarium propositionis 11 hujus) quam quod in Deo quatenus nostræ mentis essentiam constituit, detur idea adæquata et perfecta et consequenter (per propositionem 32 hujus) nihil aliud dicimus quam quod talis idea sit vera. Q.E.D.
