What happens
Descartes explores the nature of error and truth, arguing that error arises from the misuse of free will when the will extends beyond the clear and distinct perceptions of the understanding.

Key passages
“I am thus able now without difficulty to abstract my mind from the contemplation of [sensible or] imaginable objects, and apply it to those which, as disengaged from all matter, are purely intelligible.”
I can now easily focus my mind on purely intellectual things, separate from material or sensory images.
Descartes emphasizes the shift from sensory to intellectual contemplation.
“For, in the first place, I discover that it is impossible for him ever to deceive me, for in all fraud and deceit there is a certain imperfection.”
First, I realize that God cannot deceive me because deception implies imperfection.
God's perfection precludes any possibility of deception.
“I observe that these depend on the concurrence of two causes, viz., the faculty of cognition, which I possess, and that of election or the power of free choice—in other words, the understanding and the will.”
I see that error results from the combination of my understanding and my free will.
Error arises when the will judges beyond what the understanding clearly perceives.
