Some Findings: Conceptual frameworkSome Findings: Conceptual framework

If men were angels, no government would be necessary.

If angels were to govern men, neither external nor internal controls would be necessary.

In framing a government which is to be administered by men over men, the great difficulty lies in this: you must first enable the government to control the governed; and in the next place oblige it to control itself.

James Madison, Federalist Papers, 1788
