(That seems at least a bit questionable. It is easy to get the impression reading Heinlein's fiction that the philosophical views are being lampooned rather than propagated. People who agree with the views probably think Heinlein is putting them seriously. Those who disagree either think Heinlein is having a joke, or throw the book away. It is also worth noting that these "philosophical views" are much less visible in his earlier works and only become strong starting with The Cat Who Walks Through Walls, a work which had better be a joke at every level or it is just garbage.)
Heinlein's personal views are well-documented from non-fiction works and interviews. No attempt was made to make novels consistent with any overall system of ideas, but it is clear that Heinlein sympathized with the views expressed by his sympathetic characters.
Please provide years for the works. It would also be nice to sort by years, see discussion on Wikipedia policy.
Someone is going to have to justify the narrowmindedness of Kansas City, MO, more clearly than is currently done in the article. When Heinlein was born it was an incredibly dynamic place (ever heard of the Blues? Jazz? The meatpacking industry? The Nelson-Atkins Museum of Art?). Heinlein may have come from a narrowminded and provincial family, or have been packed off to visit narrowminded and provincial relatives elsewhere in Missouri, but I really think that blaming it on Kansas City is ill-informed. I am, I am quick to offer as a disclaimer, neither a Midwesterner nor even a frequent visitor. I have a strong feeling that Heinlein would have grown up to be much the same no matter where he had done the growing up. --MichaelTinkler
