It makes no sense to want to change everything all at once, or to preserve everything forever. The political Left is defined, first and foremost, by its desire to tear down the existing society and build some preconceived utopia on the ruins. No wonder the Right has habitually regarded the future as a menace. The irony is that it's the utopians, from Plato on down to the feminists and environmentalists, who believe that society is, or can be, eternally fixed and inalterable. Utopians underestimate the complexity and dynamism of the world, and overestimate the power of a simple and static order.
Society is too complex, unpredictable, and deeply rooted to be designed or recreated by anyone.
Every plan for the complete reconstruction of society must be rejected outright, no matter what goals it aims at. The world has a certain resistence to the force of human intentions, a certain inertia, even a certain perversity. There are two reasons for this. The first is that man is not omniscient, and therefore all our actions have unforeseeable consequences. Tradition, the inherited wisdom of the race, is simply the accumulation of the wisdom of individuals.
