The main strength of conservatism

Conservatism at its best fits youth into maturity, which is like fitting meritocracy into aristocracy. Time and experience allow cultural maturity to accumulate, but we need to avoid aristocracies where merit has slipped and become effete snobbery. But meritocracies alone can bring unethical, uncultured, bright monsters. We need both youth and maturity, both meritocracy and aristocracy. I think conservatism can do this, which is the main strength of conservatism, when it's working at its best. This applies to politics as well as religion. Even science can benefit from the conservative approach. This is also mainly the way evolution works---radical revolution usually harms more than it helps.
