- National honor is the national property of the highest value.
- First Inaugural Address (4 March 1817).
- The mention of Greece fills the mind with the most exalted sentiments and arouses in our bosoms the best feelings of which our nature is capable.
- Message to Congress (December 1822).
- What was the origin of our slave population? The evil commenced when we were in our Colonial state, but acts were passed by our Colonial Legislature, prohibiting the importation, of more slaves, into the Colony. These were rejected by the Crown. We declared our independence, and the prohibition of a further importation was among the first acts of state sovereignty. Virginia was the first state which instructed her delegates to declare the colonies independent. She braved all dangers. From Quebec to Boston, and from Boston to Savannah, Virginia shed the blood of her sons. No imputation then can be cast upon her in this matter. She did all that was in her power to do, to prevent the extension of slavery, and to mitigate its evils.
- Speech in the Virginia State Convention for altering the Constitution (2 November 1829).
The Monroe Doctrine (2 December 1823)
- The American continents, by the free and independent condition which they have assumed and maintain, are henceforth not to be considered as subjects for future colonization by any European power.
- In the wars of the European powers in matters relating to themselves we have never taken any part, nor does it comport with our policy so to do.
- We owe it, therefore, to candor and to the amicable relations existing between the United States and those powers to declare that we should consider any attempt on their part to extend their system to any portion of this hemisphere as dangerous to our peace and safety. With the existing colonies or dependencies of any European power we have not interfered and shall not interfere. But with the Governments who have declared their independence and maintain it, and whose independence we have, on great consideration and on just principles, acknowledged, we could not view any interposition for the purpose of oppressing them, or controlling in any other manner their destiny, by any European power in any other light than as the manifestation of an unfriendly disposition toward the United States.
