It meant throwing out all but the first couple of chapters of what I had written so far (and, in fact, I ended up completely writing the novel from the beginning), but it soon dawned on me that it was worth doing, for this was the final idea, the one that would pull me through the whole book. I had observed before that one thing wrong with science fiction as a whole was that almost all the heroes seemed to spring fully-grown from the head of Zeus--no one had families. If there was a mention of parents at all, it was to tell us they were dead, or such miserable specimens of humanity that the hero could hardly wait to get out of town.

Not only did they have no parents, few science fiction heroes seemed to marry and have kids. In short, the heroes of most science fiction novels were perpetual adolescents, lone rangers who wandered the universe avoiding commitments. This shouldn't be surprising. The romantic hero is invariably one who is going through the adolescent phase of human life. The child phase--the one I had dealt with most often in my fiction--is the time of complete dependence on others to create our identity and our worldview. Little children gladly accept even the strangest stories that others tell them, because they lack either the context or the confidence to doubt. They go along because they don't know how to be alone, either physically or intellectually.

Gradually, however, this dependency breaks down--and children catch the first glimmers of a world that is different from the one they thought they lived in, they break away the last vestiges of adult control themselves, much as a baby bird breaks free of the last fragments of the egg. The romantic hero is unconnected. He belongs to no community; he is wandering from place to place, doing good (as he sees it), but then moving on. This is the life of the adolescent, full of passion, intensity, magic, and infinite possibility; but lacking responsibility, rarely expecting to have to stay and bear the consequences of error. Everything is played at twice the speed and twice the volume in the adolescent--the romantic--life.
