 The whole project of the Fourth Meditation would appear to suggest that Descartes is committed to the view that human beings can do something other than what God preordains. The Fourth Meditation tells us that error is avoidable, that we err not as as a result of the way that we are constructed but as a result of our mis-use of one of the faculties that God has provided us, and that to avoid error we must refrain from affirming what we do not perceive clearly and distinctly.
