You will never be alone with a poet in your pocket.

I must study politics and war that my sons may have liberty to study mathematics and philosophy. My sons ought to study mathematics and philosophy, geography, natural history, naval architecture, navigation, commerce, and agriculture, in order to give their children a right to study painting, poetry, music, architecture, statuary, tapestry, and porcelain.

Thomas Jefferson still lives.

Statesmen may plan and speculate for liberty but it is religion and morality alone that can establish the principles upon which freedom can securely stand.

Jefferson still survivies.

Old minds are like old horses; you must exercise them if you wish to keep them in working order.

Had I been chosen President again, I am certain I could not have lived another year.

We have no government armed with power capable of contending with human passions unbridled by morality and religion. Avarice, ambition, revenge or gallantry would break the strongest cords of our Constitution as a whale goes through a net. Our Constitution is designed only for a moral and religious people. It is wholly inadequate for any other.

Children should be educated and instructed in the principles of freedom.

I always consider the settlement of America with reverence and wonder, as the opening of a grand scene and design in providence, for the illumination of the ignorant and the emancipation of the slavish part of mankind all over the earth.

But a Constitution of Government once changed from Freedom, can never be restored. Liberty, once lost, is lost forever.

The proposition that the people are the best keepers of their own liberties is not true. They are the worst conceivable, they are no keepers at all; they can neither judge, act, think, or will, as a political body.

Liberty cannot be preserved without a general knowledge among the people.

There is danger from all men. The only maxim of a free government ought to be to trust no man living with power to endanger the public liberty.

No man who ever held the office of president would congratulate a friend on obtaining it.

...a revolution of government is the strongest proof that can be given by a people of their virtue and good sense.

In my many years I have come to a conclusion that one useless man is a shame, two is a law firm, and three or more is a congress.
