The book consists of 15 articles by Schulman and a foreword by Brad Linaweaver.

Four of these articles are previously published reviews of Heinlein's novels Revolt in 2100, Time Enough for Love, Job: A Comedy of Justice and The Moon Is a Harsh Mistress.

More than half of the book consists of the transcript of a three-and-a-half hour taped interview with Heinlein that Schulman conducted by telephone in June 1973.

Subjects Heinlein talks about include evolution, general semantics, art and commercialism, the space program, kinds of libertarianism, sex, communism, his Future History series, high school reading lists, science fiction writing, the afterlife, UFOs, house building, artificial intelligence and voting rights.
