We may be assured by past experience, that such a practice [as some states charging high taxes on goods from other states] would be introduced by future contrivances; and both by that and a common knowledge of human affairs, that it would nourish unceasing animosities, and not improbably terminate in serious interruptions of the public tranquility.

In framing a system, which we wish to last for ages, we should not lose sight of the changes which ages will produce.

Is there no virtue among us? If there be not, we are in a wretched situation. No theoretical checks-no form of government can render us secure. To suppose that any form of government will secure liberty or happiness without any virtue in the people, is a chimerical idea, if there be sufficient virtue and intelligence in the community, it will be exercised in the selection of these men. So that we do not depend on their virtue, or put confidence in our rulers, but in the people who are to choose them.

The Convention thought it wrong to admit in the Constitution the idea that there could be property in men.
