The prototype of the rule creator, but not the only variety as we shall see, is the crusading reformer. He is interested in the content of rules. The existing rules do not satisfy him because there is some evil which profoundly disturbs him. He feels that nothing can be right in the world until rules are made to correct it. He operates with an absolute ethic; what he sees is truly and totally evil with no qualification. Any means is justified to do away with it. The crusader is fervent and righteous, often self-righteous.

There is no reason to assume that only those who finally commit a deviant act actually have the impulse to do so. It is much more likely that most people experience deviant impulses frequently. At least in fantasy, people are much more deviant than they appear. Instead of asking why deviants want to do things that are disapproved of, we might better ask why conventional people do not follow through on the deviant impulses they have. Something of an answer to this question may be found in the process of commitment through which the “normal” person becomes progressively involved in conventional institutions and behavior.

Imagine you are doing a woodworking project, perhaps making a table. Fortunately, you needn't make all the parts yourself. Some are standard sizes and shapes - lengths of two by four, for instance - available at any lumberyard. Some have already been designed and made by other people - drawer pulls and turned legs. All you have to do is fit them into the places you left for them, knowing they were available. You want to make an argument instead of a table. You have created some of the argument yourself, perhaps on the basis of new data or information you have collected. But you needn't invent the whole thing. Other people have worked on your problems or problems related to it, and have made some of the pieces you need. You just have to fit them in where they belong. Like the woodworker, you leave space, when you make your portion of the argument, for the other parts you know you can get. You do that, that is, if you know that they are there to use. And that's one good reason to know the literature: so that you will know the pieces are available and not waste time doing what has already been done.
