  Descartes cannot be saved entirely from this charge, but two important points can be made in his defense. First, he has principled reasons for thinking that everyone has the same set of innate or clear and distinct ideas. When the meditator first proved God’s existence in the Third Meditation, she also established that God is supremely good and hence no deceiver. One consequence of God’s perfect benevolence is that he implanted the same set of innate ideas in all finite minds. Thus, Descartes feels justified in concluding that the limits of his capacity for clear and distinct perception will be shared by everyone.
