Name that Monument/Memorial Part 3

Tonight's run included a stop at a memorial for a president who emphasized the connection between light and liberty. Besides saying "Light and liberty go together," this president also said, "I know no safe depositary of the ultimate powers of the society but the people themselves; and if we think them not enlightened enough to exercise their control with a wholesome discretion, the remedy is not to take it from them, but to inform their discretion by education. This is the true corrective of abuses of constitutional power."

Any guesses? I suppose a "no googling" rule would be difficult to enforce, but it's less fun if you google the quotes.
