 The problem of extrapolating to modern political affairs can be illustrated more fully in connection with Aristotle’s discussion of legal change in Politics II.8. He first lays out the argument for making the laws changeable. It has been beneficial in the case of medicine, for example, for it to progress from traditional ways to improved forms of treatment. An existing law may be a vestige of a primitive barbaric practice. For instance, Aristotle mentions a law in Cyme that allows an accuser to produce a number of his own relatives as witnesses to prove that a defendant is guilty of murder. “So,” Aristotle concludes, “it is evident from the foregoing that some laws should sometimes be changed. But to those who look at the matter from a different angle, caution would seem to be required” (1269a12–14). Since the law gets its force from the citizens’ habit of obedience, great care should be exercised in making any change in it. It may sometimes be better to leave defective laws in place rather than encouraging lawlessness by changing the laws too frequently. Moreover, there are the problems of how the laws are to be changed and who is to change them. Although Aristotle offers valuable insights, he breaks off the discussion of this topic and never takes it up elsewhere. We might sum up his view as follows: When it comes to changing the laws, observe the mean: don’t be too bound by traditional laws, but on the other hand don’t be overeager in altering them. It is obvious that this precept, reasonable as it is, leaves considerable room for disagreement among contemporary “neo-Aristotelian” theorists. For example, should the laws be changed to allow self-described transsexual persons to use sexually segregated restrooms? Conservatives and liberals might agree with Aristotle’s general stricture regarding legal change but differ widely on how to apply it in a particular case.
