Why do you think Madison held this view of the “separation of powers”

James Madison begins this paper by telling his readers that he is going to examine a specific principle of republican government: "separation of powers." One of the principal objections to the constitution is that it violates this important principle. Its opponents claim that the three branches of government are not sufficiently separate and independent and that power is too unevenly distributed. It is feared that the new government will collapse, and that liberty will be threatened.

Madison agrees with those who place great importance on the separation of powers, especially on the point that an unequal division of power could result in the loss of liberty. If one branch has too much power, it does not matter how many men govern or how they obtain office. Too much power in one branch of government "is the very definition of tyranny." If these claims were true, Madison says that no other arguments would need oppose it. He, however, is convinced that this charge cannot be supported. How separate should each branch of government be?
