Checks and Balances & the Separation of Powers
Montesquieu / The Federalists · 1748
"Montesquieu and the Federalists argued that concentrating power in one body makes its abuse inevitable — so liberty requires splitting power across competing institutions that can check each other."
Montesquieu wrote in 1748 that any person with power is apt to abuse it. The American founders took that warning and built three branches that can each block the other two.
Separation assigns distinct functions — legislature, executive, judiciary — to distinct bodies with distinct selection and tenure, while checks give each a veto over the others (veto, confirmation, judicial review). The design assumes ambition will counteract ambition, rather than hoping office-holders become virtuous. Institutional version of incentives: make abuse expensive by requiring collusion across independent bodies rather than willpower from a single one.
