Themes What ties most of the stories together is that they are an examination and deconstruction of incest. In the context of his "tales" Heinlein examines the morality of a variety of possible incestuous situations: from unrelated "twins", to unrelated parent-child, to distant relatives, and finally close relatives when Lazarus sleeps with his own mother. Heinlein seems to conclude that, absent genetic risk, it is not immoral at all.
