I think I learned this from Francis Fukuyama: The hard left and hard right are both revolutionary. One wants to destroy the present to make way for a utopian future that has never been. The other wants to destroy the present to restore an idealized past that never was.

Liberalism and conservatism want to both conserve and reform the present. Their disagreement is mainly concerning degree and rate of change. Both know that politics develops organically and must be cultivated. Political orders cannot be dismantled, reengineered and reassembled.

Revolutions are disasters. The only people who want them are those who should never be in charge of anything.
