Richard Henry Lee - on the reason for a bill of rights, which is why his fellow Virginian Thomas Jefferson later referred to the 10th Amendment as "the foundation of the Constitution"

Lee attempted to include a bill of rights with the Constitution before the Confederation Congress sent it to the states for ratification:

"A bill of rights not necessary in the Confederation because it is expressly declared that no power should be exercised, but such as is expressly given, and therefore no constructive power can be exercised. To prevent this is the great use of a bill of rights."
-Richard Henry Lee, Confederation Congress (27 Sept 1787)
