"The delight and thoroughness of this book are enough to convert any
  lover of ideas and words to a belief in ismism."

--Richard Lederer, author of Anguished English, The Miracle of Language, et al

The only ism Hollywood believes in is Plagiarism
Dorothy Parker (1893-1967)

Very few isms are actually beneficial and therefore worth remembering, but they will help you appreciate the manifold silliness of humanity in its quest to organize and explain itself. Do not become alarmed if we occasionally ridicule a sacred cow. Independent research has shown conclusively that cows don't give a hoot about being ridiculed. It is noteworthy that only TWO of the following isms can be attributed to women. The time has come for more women to conceive and organize their thinking in philosophical terms for the benefit of future generations. Click on any ism to see its definition. See also Political and Economic Isms, and a separate category dealing with religion in the Atrium.
