As quoted in The Best Liberal Quotes Ever : Why the Left is Right (2004) by William P. Martin. Though widely attributed to Henry, this statement has not been sourced to any document before the 1990s and appears to be at odds with his beliefs as a strong opponent of the adoption of the US Constitution.

Judge Napolitano on Hannity and Colmes http://www.youtube.com/watch?v=bejmEG_t9mI, discussing the Supreme Court rulings on the scope of the protections in the Constitution.
Context: The Constitution applies to persons, not just citizens. If you read the Constitution, its protections are not limited to Americans. And that was written intentionally, because at the time it was written, they didn't know what Native Americans would be. When the post civil war amendments were added, they didn't know how blacks would be considered, because they had a decision of the Supreme Court called Dred Scott, that said blacks are not persons. So in order to make sure the Constitution protected every human being: American, alien; citizen, non-citizen; lawful combatant, enemy combatant; innocent, guilty; those who wish us well, those who wish us ill... they use the broadest possible language, to make it clear: Wherever the government goes, the Constitution goes, and wherever the Constitution goes, the protections that it guarantees restrain the government and requires it to protect those rights.

Lucy Rail, and Cayle Clark in Ch. 5
The Weapon Shops of Isher (1951)
Context: "You really don't understand. We don't worry about individuals. What counts is that many millions of people have the knowledge that they can go to a weapon shop if they want to protect themselves and their families. And, even more important, the forces that would normally try to enslave them are restrained by the conviction that it is dangerous to press people too far. And so a great balance has been struck between those who govern and those who are governed."
Cayle stared at her in bitter disappointment. "You mean that a person has to save himself? Even when you get a gun you have to nerve yourself to resist? Nobody is there to help you?"
It struck him with a pang that she must have told him this in order to show him why she couldn't help him.
Lucy spoke again. "I can see that what I've told you is a great disappointment to you. But that's the way it is. And I think you'll realize that's the way it has to be. When a people lose the courage to resist encroachment on their rights, then they can't be saved by an outside force. Our belief is that people always have the kind of government they want and that individuals must bear the risks of freedom, even to the extent of giving their lives."

Interior Castle (1577)
Context: Just as we cannot stop the movement of the heavens, revolving as they do with such speed, so we cannot restrain our thought. And then we send all the faculties of the soul after it, thinking we are lost, and have misused the time that we are spending in the presence of God. Yet the soul may perhaps be wholly united with Him in the Mansions very near His presence, while thought remains in the outskirts of the castle, suffering the assaults of a thousand wild and venomous creatures and from this suffering winning merit. So this must not upset us, and we must not abandon the struggle, as the devil tries to make us do. Most of these trials and times of unrest come from the fact that we do not understand ourselves.
