A definitional distinction between freedom and liberty has had enormous real world ramifications. From Brian Miller at ammo.com:
“I see the liberty of the individual not only as a great moral good in itself (or, with Lord Acton, as the highest political good), but also as the necessary condition for the flowering of all the other goods that mankind cherishes: moral virtue, civilization, the arts and sciences, economic prosperity. Out of liberty, then, stem the glories of civilized life.”
The terms “freedom” and “liberty” have become clichés in modern political parlance. Because these words are invoked so much by politicians and their ilk, their meanings are almost synonymous and used interchangeably. That’s confusing – and can be dangerous – because their definitions are actually quite different.
“Freedom” is predominantly an internal construct. Viktor Frankl, the legendary Holocaust survivor who wrote Man’s Search For Meaning, said it well: “Everything can be taken from a man but one thing: the last of the human freedoms – to choose one’s attitude in any given set of circumstances, to choose one’s own way (in how he approaches his circumstances).”
In other words, to be free is to take ownership of what goes on between your ears, to be autonomous in thoughts first and actions second. Your freedom to act a certain way can be taken away from you – but your attitude about your circumstances cannot – making one’s freedom predominantly an internal construct.
On the other hand, “liberty” is predominantly an external construct. It’s the state of being free within society from oppressive restrictions imposed by authority on one’s way of life, behavior, or political views. The ancient Stoics knew this (more on that in a minute). So did the Founding Fathers, who wisely noted the distinction between negative and positive liberties, and codified that difference in the U.S. Constitution and Bill of Rights.
