James Madison

“Liberty and order will never be perfectly safe, until a trespass on the constitutional provisions for either, shall be felt with the same keenness that resents an invasion of the dearest rights; until every citizen shall be an Argus to espy, and an Ægeon to avenge, the unhallowed deed.”
“Charters,” published in the National Gazette on January 19, 1792 (dated January 18, 1792).
