Answer:
John Locke: Natural rights
Baron de Montesquieu: Checks and balances
Voltaire: Importance of religious tolerance
Step-by-step explanation:
Montesquieu argued that the best way to prevent despotism was through a separation of powers, and a system of checks and balances intended to guarantee that no branch would seize too much power.
In his Treatise on Toleration, Voltaire claimed that religious intolerance was against the law of nature.
Locke’s theory about Life, Liberty, and Property beeing natural rights, was the foundation of the French Revolution and the Declaration of the Rights of Man.
