Original meaning
Originalists of all stripes cite "The Federalist Papers". It is fairly tenuous to suggest that this represents a good source for the original "intent": after all, Alexander Hamilton, who wrote the majority of those essays, was absent for the greater part of the Philadelphia Convention, and John Jay did not attend it at all. However, James Madison, the principal framer of the Constitution also wrote a substantial amount of "The Federalist Papers". Also, to suggest Hamilton and Jay's absence from the convention implies their ignorance as to the Constitution's original meaning is demeaning to those two men and inaccurate. The collected anti-Federalist papers, of course, will be no use at all to a person searching for the original "intent" of the framers. However, as evidence of how a reasonable person at the time would have understood the words of the Constitution, "The Federalist Papers" and the anti-Federalist essays are evidence of direct relevance.
The Federalist Papers
However, Hamilton's opposition to a Bill of Rights was far from universal. Robert Yates, writing under the pseudonym "Brutus", articulated this view point in the so-called Anti-Federalist No. 84, asserting that a government unrestrained by such a bill could easily devolve into tyranny. References in "The Federalist" and in the ratification debates warn of demagogues of the variety who through divisive appeals would aim at tyranny. "The Federalist" begins and ends with this issue. In the final paper Hamilton offers "a lesson of moderation to all sincere lovers of the Union, and ought to put them on their guard against hazarding anarchy, civil war, a perpetual alienation of the States from each other, and perhaps the military despotism of a successful demagogue". The matter was further clarified by the Ninth Amendment.
