Federalist 10
James Madison, 4th President of the United States, wrote this essay on how to mitigate the “mischiefs of faction” in government in 1787. He noted the need to find balance – “In the first place, it is to be remarked that, however small the republic may be, the representatives must be raised to a certain number, in order to guard against the cabals of a few; and that, however large it may be, they must be limited to a certain number, in order to guard against the confusion of a multitude.” http://www.bit.ly/yale-madison
