"If we are to build a better world, we must have the courage to make a new starteven if that means some reculer pour mieux sauter. It is not those who believe in inevitable tendencies who show this courage, not those who preach a 'New Order' which is no more than a projection of the tendencies of the last forty years, and who can think of nother better than to imitate Hitler" (The Road to Serfdom, Friedrich August Hayek, 1944).
Don't worry, this is as political as I will ever get.
