Final answer:
Thomas Aquinas's concept of natural law, emphasizing universal moral principles derived from nature and reason, significantly influenced Enlightenment thinkers and lawmakers, serving as a foundation for their ideas on individual rights, social contracts, and the limits of government authority.
Step-by-step explanation:
Aquinas's notion of natural law, rooted in reason and the innate moral order, resonated strongly during the Enlightenment period. His emphasis on fundamental moral principles inherent in nature aligned with Enlightenment philosophers' pursuits of rationality, individual rights, and the social contract theory. Figures like John Locke and Jean-Jacques Rousseau drew upon Aquinas's ideas to assert that governments should protect natural rights, emphasizing consent-based governance and the obligation to serve the people. The Enlightenment's emphasis on reason, human rights, and the limitation of governmental power found resonance in Aquinas's notion of natural law, shaping the foundation of legal and philosophical thought during that era.
