What is the main idea of the Madison quote?

"The accumulation of all powers, legislative, executive, and judiciary, in the same hands, whether of one, a few, or many, and whether hereditary, self-appointed, or elective, may be justly pronounced the very definition of tyranny (L)iberty requires that the three great departments of power should be separate and distinct.

separation of powers

Explanation:

The main idea of the Madison quote is Separation of power at the National level into three different arms of Government ( executive , Judiciary and legislative ) arms of Government. and each arm of government will check mate each other to avoid the abuse of powers by any arm of Government.

Madison feared that if all powers where given to a single arm of government at the National level there will be a huge likely hood of tyranny/abuse of power, because there would be no " checks and balance "  on the government .

propriety is the answer. hope this !
