Final answer:
Enlightenment ideas, particularly Montesquieu's separation of powers and John Locke's natural law theories, significantly shaped the Founding Fathers' creation of the U.S. Constitution and Declaration of Independence, informing the system of checks and balances and individual rights respectively. The correct options are B and C.
Step-by-step explanation:
The Enlightenment ideas greatly influenced the Founding Fathers of the United States. Montesquieu's view on the separation of powers led to the establishment of a system of checks and balances within the U.S. Constitution, ensuring no single branch would dominate the government (B). Similarly, John Locke's theories on natural law and the social contract molded the Founders' views on individual rights and the government's role in protecting those rights (C).
The Constitution reflects these Enlightenment principles through its embodiment of shared power among the executive, legislative, and judicial branches. The ideas of natural rights to life, liberty, and property that were advocated by John Locke are also echoed in the Declaration of Independence, where Jefferson famously refers to "life, liberty, and the pursuit of happiness" as inalienable rights.
Ultimately, the Founding Fathers did not reject Enlightenment ideas but rather embraced them to form the foundational governance principles of the new nation. Therefore, options A and D, which suggest the Founding Fathers rejected or were not influenced by Enlightenment ideas, do not align with historical evidence.
