This psychology of humor, adorned with 700 exquisite jokes, is a classic that has long been out of print and is now presented here in an expanded edition. It is a welcome reading book for anyone who enjoys laughing and wants to understand why they do so - as far as science has figured it out. The work has also been highly praised for its examples of humor, which provide clarity and enjoyment - as well as insights. In this school of laughter, the examples are so intelligently grouped that gradually - across 67 chapters - all techniques or tendencies of the comedic become illuminated.
