The paradox that James Madison creates in the Federalist No. 51 is when he says, “If men were angels, no government would be necessary. If angels were to govern men, neither external nor internal controls on government would be necessary.” Men are not angels, therefore a government is necessary. James Madison says that the solution to this paradox is the Constitution’s separation of powers. Each of the branches of government has a way to limit the power of another branch. In this journal from James Madison, he outlines the details of the separated system.
The primary control on the government is the dependence on the people. An auxiliary precaution is a republican government, which is pure democracy versus republic. Another is the separation of powers and checks and balances. With separating the government into two it gives us double security because “The different governments will control each other, at the same time that each will be controlled by itself.”
