What does Descartes claim was the source of all of his former erroneous beliefs? What does Descartes mean when he says it is the source of
them? How does Descartes propose to insure he will not be misleadagain by this source? What objections does Descartes consider to his
proposed plan? How does he answer them? What final skeptical worry does Descartes raise at the end of Meditation I, and how does he,
rather poetically, express that worry by hypothesizing an “evil genius”?
