Perhaps there is nothing in Nature more pleasing than the study of the human mind, even in its imperfections or depravities; for, although it may be more pleasing to a good mind to contemplate and investigate the application of its powers to good purposes, yet as depravity is an operation of the same mind, it becomes at least equally necessary to investigate, that we may be able to prevent it.
-John Hunter
