I made up the following list of "The Three Laws of Models." 1. No model can be an exact representation of the complexities of empirical reality.
2. The predictions implied by any model vary as the assumptions change. 3. No model applies to answer all questions (to predict in all domains) because no model can tell the whole story. does anyone have any comments? is there anything I can add to the list? (A fourth presents a problem: Isaac Asimov had only three laws of robotics and I don't want to exceed his effort.) -- Jim Devine / "Segui il tuo corso, e lascia dir le genti." (Go your own way and let people talk.) -- Karl, paraphrasing Dante.
