The Federalist The Famous Papers on the Principles of American Government
This subtitle to my edition is "The Famous Papers on the Principles of American Government." It's an apt description, but perhaps doesn't go far enough. Try foundational. They consist of 85 essays by Alexander Hamilton, who became our first Secretary of the Treasury, James Madison, who largely framed the United States Constitution, and John Jay, who became our first Chief Justice of the Supreme Court. The essays were written to urge people to ratify the constitution, and have been used every since to illuminate it by everyone from judges to--well, political science professors, and this was one of my texts in my college course introducing political science.
It may be this edition regularized grammar and spelling, but one thing that hit me is how readable it all is. It was meant to explain the constitution to ordinary voters, so perhaps that shouldn't be so surprising. If I could get Americans to read one book, this would be my choice. Whether they agree with the principles of the Founders who created this country or not, at least by the end of it they'd understand what--and what they were not--about, and not just who the pundits and politicians claim for them. But if I couldn't get them to read the whole thing, I'd at least urge on them "Federalist No. 10" by James Madison. Our professor taught us that particular essay was at the heart of the philosophy of American Government and the design of the constitution:
Liberty is to faction, what air is to fire, an aliment, without which it instantly expires. But it could not be a less folly to abolish liberty, which is essential to political life, because it nourish faction, than it would be to wish the annihilation of air, which is essential to animal life, because it imparts to fire its destructive agency.
It is to control faction (think political parties) and the strife that tore previous democracies to pieces, without sacrificing liberty that the separation of powers and system of checks and balances was written into the constitution. As that particular essay elegantly explains. If the Constitution is our text book, the Federalist Papers is the Constitution 101 for Dummies, the owners' manual.
