79/106 Knowledge of the second and third kinds, not knowledge of the first kind, teaches us to distinguish the true from the false. 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. He, who has a true idea, simultaneously knows that he has a true idea, and cannot doubt of the truth of the thing perceived. |
