On the politician-
He who is unfit to serve his fellow citizens wants to rule them.
Once you begin to admit that it is the duty of the government to control your consumption of alcohol, what can you reply to those who say the control of books and ideas is much more important?
On the free man (via the Mises blog)-
The propensity of our contemporaries to demand authoritarian prohibition as soon as something does not please them, and their readiness to submit to such prohibitions even when what is prohibited is quite agreeable to them shows how deeply ingrained the spirit of servility still remains within them…. A free man must be able to endure it when his fellow men act and live otherwise than he considers proper. He must free himself from the habit, just as soon as something does not please him, of calling for the police.
