Final answer:
The two ideas of the Enlightenment thinkers that are contained in the U.S. Constitution are popular sovereignty and limited government.
Step-by-step explanation:
The two ideas of the Enlightenment thinkers that are contained in the U.S. Constitution are popular sovereignty and limited government.
Popular sovereignty means that the power of the government comes from the consent of the people. This idea is seen in the opening words of the Constitution, 'We the People,' which acknowledges that political power comes from the governed.
Limited government means that the powers of the government are restricted to protect individual rights and prevent abuse of power. The Constitution establishes a system of checks and balances, separating power among the three branches of government and preventing any one branch from becoming too powerful.
