Notes on the State of Virginia, Query 14 — 1781
History by apprising [citizens] of the past will enable them to judge of the future; it will avail them of the experience of other times and other nations; it will qualify them as judges of the actions and designs of men; it will enable them to know ambition under every disguise it may assume; and knowing it, to defeat its views.
letter to John Adams — 1817
A morsel of genuine history is a thing so rare as to be always valuable.
"If Congress can do whatever in their discretion can be done by money, and will promote the General Welfare, the Government is no longer a limited one, possessing enumerated powers, but an indefinite one, subject to particular exceptions." —James Madison (1792)
