Final answer:
Montesquieu believed in having different powers checking each other to prevent any one branch from becoming too powerful.
Step-by-step explanation:
Montesquieu believed it was a good idea to have different powers checking each other in order to prevent any one branch from becoming too powerful.
By separating the powers of government into three distinct branches - legislative, executive, and judicial - Montesquieu argued that each branch would serve as a check on the others, ensuring a system of checks and balances.
This system would prevent the concentration of power in one branch or the establishment of an absolute monarchy.
