High Arka asks how reading Hume will make one a better person. I must confess that I am not really sure what makes one a good person. Pretty clearly, education does not. I know too many superbly education swine. Nor does a comfortable and protected childhood. Adversity seems to make some people better and some worse. The same is true for religion. Perhaps a multiple regression analysis would reveal some unsuspected factor, but I rather doubt it. Part of the problem, of course, is that opinions differ considerably about just who is a good or bad person. It is hard to do a scientific study of gravity when there is no agreement on what is up and what is down!
I can, however, suggest some other benefits that it seems to me we can derive from a close reading of Hume. The first is an appreciation for compact, powerful arguments stated simply but forcefully. A second is a recognition of the weakness of the grounds for a rational belief in a divine being. One can also gain some insight into the origins of the modern discipline of Psychology. And of course there is the sheer pleasure in the elegance and succinctness of Hume's use of English, something I very much wish more of my students over the years had managed to emulate.
None of these will make one a better person, I am sure, but they might make one a more interesting person with whom to have a conversation.
