Only the educated are free -- Epictetus, Discourses, Book II, Chapter 1

"What then is the fruit of these opinions? It is that which ought to he the most noble and the most becoming to those who are really educated, release from perturbation, release from fear, freedom. For in these matters we must not believe the many, who say that free persons only ought to be educated, but we should rather believe the philosophers, who say that the educated only are free. "How is this?" In this manner. Is freedom anything else than the power of living as we choose? "Nothing else." Tell me then, ye men, do you wish to live in error? "We do not." No one then who lives in error is free. Do you wish to live in fear? Do you wish to live in sorrow? Do you wish to live in perturbation? "By no means." No one, then, who is in a state of fear or sorrow or perturbation is free; but whoever is delivered from sorrows and fears and perturbations, he is at the same time also delivered from servitude. How then can we continue to believe you, most dear legislators, when you say, "We only allow free persons to be educated?" For philosophers say we allow none to be free except the educated; that is, God does not allow it."
