“One essential of a free government is that it rest wholly on voluntary support. And one certain proof that a government is not free, is that it coerces more or less persons to support it, against their will. All governments, the worst on earth, and the most tyrannical on earth, are free governments to that portion of the people who voluntarily support them. And all governments—though the best on earth in other respects—are nevertheless tyrannies to that portion of the people—whether few or many—who are compelled to support them against their will. A government is like a church, or any other institution, in these respects. There is no other criterion whatever, by which to determine whether a government is a free one, or not, than the single one of its depending, or not depending, solely on voluntary support.”
