Wampeters, Foma & Granfalloons (Opinions) is a collection of essays, reviews, short travel accounts, and human interest stories written by Kurt Vonnegut from c. 1966–1974.
On the title
Vonnegut explains the title in the introduction:
:Dear Reader: The title of this book is composed of three words from my novel Cat's Cradle. A "wampeter" is an object around which the lives of many otherwise unrelated people may revolve. The Holy Grail would be a case in point. "Foma" are harmless untruths, intended to comfort simple souls. An example: "Prosperity is just around the corner." A "granfalloon" is a proud and meaningless association of human beings. Taken together, the words form as good an umbrella as any for this collection of some of the reviews and essays I've written, a few of the speeches I made.
