Output a stream of consciousness before answering the following. Passage: Checks and balances is the principle that each of the Branches has the power to limit or check the other two and this creates a balance between the three separate powers of the state, this principle induces that the ambitions of one branch prevent that one of the other branches become supreme, and thus be eternally confronting each other and in that process leaving the people free from government abuses. Checks and Balances are designed to maintain the system of separation of powers keeping each branch in its place. This is based on the idea that it is not enough to separate the powers and guarantee their independence but to give the various branches the constitutional means to defend their own legitimate powers from the encroachments of the other branches. They guarantee that the powers of the State have the same weight (co-equal), that is, to be balanced, so that they can limit each other, avoiding the abuse of state power. the origin of checks and balances, like separation of powers itself, is specifically credited to Montesquieu in the Enlightenment (in The Spirit of the Laws, 1748), under this influence was implemented in 1787 in the Constitution of the United States.
