Non schola sed vita decimos!

"Only the educated are free."
Epictetus

"Enlighten the people generally, and tyranny and oppressions of body and mind will vanish like evil spirits at the dawn of day."
Thomas Jefferson

"If a man empties his purse into his head, no man can take it away from him. An investment in knowledge always pays the best interest."
Benjamin Franklin

"Education is a better safeguard of liberty than a standing army."
Edward Everett

"Education makes people easy to lead, but difficult to drive;
easy to govern, but impossible to enslave."
Henry Peter, Lord Brougham
"The Present State of the Law"

"Learned Institutions ought to be favorite objects with every free people. They throw that light over the public mind which is the best security against crafty & dangerous encroachments on the public liberty."
James Madison

"Education is a companion which no misfortune can depress, no crime can destroy, no enemy can alienate, no despotism can enslave. At home, a friend, abroad an introduction. In solitude, a solace, and in society, an ornament. It hastens vice, it guides virtue; it gives, at once, grace and government to genius. Without it, what is man? A splendid slave, a reasoning savage." 
James Addison

"What is life but the angle of vision? A man is measured by the angle at which he looks at objects. What is life but what a man is thinking of all day? This is his fate and his employer. Knowing is the measure of the man. By how much we know, so we are."
Ralph Waldo Emerson
