A Philosopher Looks at The Sense of Humor by Richard C. Richards is intended as a starting point for a philosophical discussion. A colleague once said that Richards writes about humor in a humorous way. He said there are serious books about humor, and humorous books, but a combination of the two occurs rarely. In this tour of the wide, wonderful world of the humorous, he touches upon such issues as what causes a sense of humor, whether it can be taught, what its value may be, how it is connected with happiness, and whether it should be placed on the endangered species list. He out of necessity explores the habitat of the amusing, the entertaining, and the comedic. There is considerable laughter in the world, and a more than abundant supply of things to laugh at. But since laughter and humor are only partially and not essentially connected, this may end up being a eulogy for the death of humor. Perhaps this book will cause it. We can only hope. This book may also be useful as a textbook in a classroom setting.
