Achieving a free society will take time. We might try a different analogy. Within the theory of evolution, some believe life evolves slowly, with imperceptible changes adding up over millions of years to create significant changes. Others, however, believe history is punctuated with critical moments where everything changes all at once. Libertarian political theorists have similar disagreements.
History is filled with examples of both slow and sudden changes.
The enlightenment ideals carried on by John Locke took centuries to develop, yet the American Revolution institutionalized an essentially Lockean form of government within a few short years. Socialists were quite adept at focusing their theories into the New Deal of Roosevelt. The Big Moments in history rarely take place because of the plans of any single person or group. Social forces can build for years or centuries before events reach a head. It remains an open question, however, whether we as libertarians should work for incremental change or try to help pave the way for those rare monumental changes.
