Jim Lyttle's Humor Page

Jim Lyttle wrote his dissertation on the effectiveness of a business ethics training program that used Dilbert cartoons. His thesis also explored uses of humor. His site has a number of links to a more theoretical side of humor, focusing on the nature of humor, theories of humor, and the essence of humor. Lyttle recommends two introductory books on the humor: Humor: Its Origin and Development and The Philosophy of Laughter and Humor.
