It is a misfortune, inseparable from human affairs, that public measures are rarely investigated with that spirit of moderation which is essential to… - James Madison

Had every Athenian citizen been a Socrates, every Athenian assembly would still have been a mob.

I have observed that gentlemen suppose that the general legislature will do every thing mischievous they possibly can, and that they will omit to do every thing good which they are authorized to do. If this were a reasonable supposition, their objections would be good. I consider it reasonable to conclude that they will as readily do their duty as deviate from it; nor do I go on the grounds mentioned by gentlemen on the other side — that we are to place unlimited confidence in them, and expect nothing but the most exalted integrity and sublime virtue. But I go on this great republican principle, that the people will have virtue and intelligence to select men of virtue and wisdom. 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.”
James Madison (speech at the Virginia Ratifying Convention, 20 June 1788)

Attempts to enforce by legal sanctions, acts obnoxious to so great a proportion of Citizens, tend to enervate the laws in general, and to slacken the bands of Society. If it be difficult to execute any law which is not generally deemed necessary or salutary, what must be the case, where it is deemed invalid and dangerous? And what may be the effect of so striking an example of impotency in the Government, on its general authority?
