The Problem of Error
nThe Problem of Error becomes apparent when we follow the reasoning supposing the God is all good and therefore not a deceiver.
nDescartes wonders well if this is true which he is inclined to believe, then why to we make errors at all. In other
words if we can be fooled some of the time ( which we certainly can be ) then how can we be positive that we are not fooled all of the time. This problem seems to be so difficult that Descartes decides to introduce a new hypothesis to allow him to continue and not get bogged down by it.
nRather than supposing that God is a deceiver he imagines an Evil demon or genius putting these false beliefs in our minds.
