“It’s important to talk about liberty, but not in isolation,” says Samuel Gregg, Research Director for the Acton Institute. “Our language should reflect the truth that reason, justice, equality, and virtue make freedom possible.”
At some point, for instance, those in the business of promoting freedom need to engage more precisely what they mean by liberty. After all, modern liberals never stop talking about the subject. Moreover, if the default understanding of freedom in America is reduced to Justice Anthony Kennedy’s mystery clause (“At the heart of liberty is the right to define one’s own concept of existence, of meaning, of the universe, and of the mystery of human life”), then liberty’s meaning will be very difficult to integrate with any substantive commitment to reason. That should worry freedom-lovers, because in the absence of reason we can have no principled objection—as opposed to mere emotional unease—to unjust suppressions of freedom by the sophistical, powerful, or ruthless.
