Read extremely carefully Parts I and II of David Hume's Dialogues Concerning Natural Religion (pp. 3-12). ("Extremely carefully" will likely involve at least three or four readings.)

Describe the attitude of each of the three participants (Demea, Philo, Cleanthes) toward 

     (a) the prospects of success for natural theology, i.e., for the project of demonstrating the existence and nature of God on the basis of natural reason alone, without recourse to any putative divine revelation; and 

     (b) the question of whether skepticism and, in general, pessimism with respect to the powers of reason is an ally or enemy of revealed religion, --more specifically, of the mysteries of the Christian faith; and

     (c) the question of whether belief in the mysteries of the Christian faith is foolish in the absence of philosophical demonstrations of God's existence and attributes. 

(Even though Demea doesn't say very much, you should be able to pinpoint his views from his reactions to what the others say.) 

This task should take up the first two-thirds of your paper.  In the last third,  take a stand on the following question:  Does any of the three participants espouse the position on (a), (b), and (c) laid out by St. Thomas in Summa Contra Gentiles I, chaps. 1-9--or is St. Thomas's position on these issues different from that held by any of the three participants in Hume's dialogue?  Give cogent reasons for your answer.
