Murray Rothbard: Ideas do not float in a vacuum

"...But it should be stressed that ideas do not float by themselves in a vacuum; they are influential only insofar as they are adopted and put forward by people. For the idea of liberty to triumph, then, there must be an active group of dedicated libertarians, people who are knowledgeable in liberty and are willing to spread the message to others. In short, there must be an active and self-conscious libertarian movement." ~Murray Rothbard
