1. The way to implement the theory of separation of powers in practice is to so contrive "theinterior structure of the government as that its several constituent parts may, by their mutualrelations, be the means of keeping each other in their proper places."2. Accordingly, "each department should have a will of its own; and consequently should be so constituted that the members of each should have as little agency as possible in the appointment of the members of the others."3. "It is equally evident that the members of each department should be as little dependent as possible on those of the others for the emoluments annexed to their offices."4. A: "The great security against a gradual concentration of the several powers in the same department consists in giving to those who administer each department the necessary constitutional means and personal motives to resist encroachments of the others... Ambition must be made to counteract ambition. The interests of the man must be connected with the constitutional rights of the place."B: Isn't relying on ambition and interest, "a reflection on human nature?" But, adds Madison, what is government itself but the greatest reflection on human nature? If men were angels, no government would be necessary."
