Write an essay of fewer than one thousand words that clearly and accurately explains the picture attached below. Although both Descartes and Hume intend to discover the foundations and limits of knowledge, their starting points and conclusions contrast sharply. Use your understanding of the key developments in Meditations on First Philosophy and An Enquiry Concerning Human Understanding to explain precisely how Descartes begins in doubt and ends in certainty, while Hume begins in certainty and ends in doubt. Identify a “turning point” in each case. Lastly, explain how and where each in his own way comes very close to adopting the views of a madman. Completed work is due tomorrow Tuesday April 12. 3:00 PM US Texas Time.
