“But what is liberty without wisdom, and without virtue? It is the greatest of all possible evils; for it is folly, vice, and madness, without tuition or restraint.”

Selima, Act I, Sc. 1.
Zara (1735)
Context: You talk no more of that gay nation now,
Where men adore their wives, and woman's power
Draws reverence from a polished people's softness,
Their husbands' equals, and their lovers' queens;
Free without scandal; wise without restraint;
Their virtue due to nature, not to fear.

As quoted in A Dictionary of Thoughts: Being a Cyclopedia of Laconic Quotations from the Best Authors of the World, Both Ancient and Modern (1908) by Tryon Edwards, p. 301.

Context: Virtue supposes liberty, as the carrying of a burden supposes active force. Under coercion there is no virtue, and without virtue there is no religion. Make a slave of me, and I shall be no better for it. Even the sovereign has no right to use coercion to lead men to religion, which by its nature supposes choice and liberty. My thought is no more subject to authority than is sickness or health.
