Descartes argued that when the intellect does a job of helping people interpret what they perceive, not with the help of an intellect which enters from outside, but because each human mind comes into being with innate God-given ideas, more similar then, to Plato's theory of "anamnesis", only not requiring reincarnation. Apart from such examples as the geometrical definition of a triangle, another example is the idea of God, according to the 3rd "Meditation". Error, according to the 4th "Meditation", comes about because people make judgments about things which are not in the intellect or understanding. This is possible because the human will, being free, is not limited like the human intellect.
