"Keep things simple!"Notice how the principle has strengthened in these forms which should be morecorrectly called the law of parsimony, or the rule of simplicity. To begin with, we used Occam's razor to separate theories that would predict the sameresult for all experiments. Now we are trying to choose between theories that makedifferent predictions. This is not what Occam intended. Should we not testthose predictions instead? Obviously we should eventually, but suppose we are at anearly stage and are not yet ready to do the experiments. We are just looking forguidance in developing a theory.This principle goes back at least as far as Aristotle, who wrote "Nature operates inthe shortest way possible." Aristotle went too far in believing that experimentand observation were unnecessary. The principle of simplicity works as a heuristicrule of thumb, but some people quote it as if it were an axiom of physics, which it isnot. It can work well in philosophy or particle physics, but less often so incosmology or psychology, where things usually turn out to be more complicated than youever expected. Perhaps a quote from Shakespeare would be more appropriate thanOccam's razor: "There are more things in heaven and earth, Horatio, than are dreamt ofin your philosophy.".Simplicity is subjective and the universe does not always have the same ideas aboutsimplicity as we do. Successful theorists often speak of symmetry and beauty as wellas simplicity. In 1939 Paul Dirac wrote "The research worker, in his effort toexpress the fundamental laws of Nature in mathematical form, should strive mainly formathematical beauty. It often happens that the requirements of simplicity and beautyare the same, but where they clash the latter must take precedence."The law of parsimony is no substitute for insight, logic and the scientificmethod. It should never be relied upon to make or defend a conclusion. Asarbiters of correctness, only logical consistency and empirical evidence areabsolute. Dirac was very successful with his method. He constructed therelativistic field equation for the electron and used it to predict the positron. But he was not suggesting that physics should be based on mathematical beauty alone. He fully appreciated the need for experimental verification.The final word is of unknown origin, although it's often attributed to Einstein,himself a master of the quotable one liner:"Everything should be made as simple as possible, but not simpler."The pithiness of this quote disguises the fact that no one knows whether Einsteinactually said it (this version comes from the Reader's Digest, 1977 [US: July, UK:October?). It may well be a precis of the last few pages of his "The Meaning ofRelativity" (5th edition), in which he writes of his unified field theory: "In myopinion the theory here is the logically simplest relativistic field theory that is at allpossible. But this does not mean that Nature might not obey a more complextheory. More complex theories have frequently been proposed.
