At a time when most movements that are thought to be progressive advocate further encroachments on individual liberty, those who cherish freedom are likely to expend their energies in opposition. In this they find themselves much of the time on the same side as those who habitually resist change.

Freedom granted only when it is known beforehand that its effects will be beneficial is not freedom.
