Expanded Universe

Goodread tells us "The Wit and Wisdom of Robert A. Heinlein, author of multiple New York Times best sellers, on subjects ranging from Crime and Punishment to the Love life of the American Teenager; from Nuclear Power to the Pragmatics of Patriotism; from Prophecy to Destiny; from Geopolitic to Post-Holocaust America; from the Nature of Courage to the Nature of Reality; it's all here and it's all great - straight from the mind of the finest science fiction writer of them all. But beware: after reading it, you too will occupy an Expanded Universe!"
