"One reason why Star Trek has endured from one generation to the next is that most of the stories themselves are indeed moral fables. Though the episodes are obviously self-contained, when taken as a whole they constitute a harmonious philosophy filled with hope. While our Star Trek heroes are far from perfect, they are nonetheless essentially decent beings whose interaction with "new life and new civilizations" is always guided by nobility and morality."
