Nuts and Bolts

Abstract

There is nothing so practical, someone once observed, as a good theory. Theories are sometimes viewed as abstractions from real life. And in a sense, that is what a good theory is. But a good theory organizes some aspect of life in a systematic way and allows us to understand phenomena in ways that we have not previously thought of them and to put this understanding to use. Now that we have outlined our treatment approach, we can begin to turn to the issue of putting it to use.
