Justice Scalia on Lack of a Guiding Principle for Evolution of Constitution
My pointing out that the American people may be satisfied with a reduction of their liberties should not be taken as a suggestion that the proponents of The Living Constitution follow the desires of the American people in determining how the Constitution should evolve. They follow nothing so precise; indeed, as a group they follow nothing at all. Perhaps the most glaring defect of Living Constitutionalism, next to its incompatibility with the whole anti-evolutionary purpose of a constitution, is that there is no agreement, an no chance of agreement, upon what is to be the guiding principle of the evolution. Panta rei is not a sufficiently informative principle of constitutional interpretation. What is it that judge must consult to determine when, and in what direction, evolution has occurred? Is it the will of the majority, discerned from newspapers, radio talk shows, public opinion polls, and chats at the country club? Is it the philosophy of Hume, or of John Rawls, or of John Stuart Mill, or of Aristotle? As soon as the discussion goes beyond the issue of whether the Constitution is static, the evolutionists divide into as many camps as there are individual views of the good, the true, and the beautiful. I think that is inevitably so, which means that evolutionism is simply not a practicable constitutional philosophy.

[T]he difficulties and uncertainties of determining original meaning and applying it to modern circumstances are negligible compared with the difficulties and uncertainties of the philosophy which says that the Constitution changes; that the very act which it once prohibited it now permits, and which it once permitted it now forbids; and that the key to that change is unknown and unknowable.
