Which concept reflects a belief in the power of human reason to improve society?

Rationalism reflects a belief in the power of human reason to improve society. This philosophical movement emphasizes the role of reason as the primary source of knowledge and understanding, suggesting that through rational thought and inquiry, individuals can discern truth and effect positive change in the world. During the Enlightenment, which was a significant influence on American thought and governance, rationalist ideas were instrumental in advocating for democracy, individual rights, and scientific advancement.

Rationalism's emphasis on reason as a tool for societal progress aligns with the beliefs of influential thinkers who promoted the idea that human beings are capable of solving problems and ameliorating their conditions through logical thought. This perspective laid the groundwork for many reforms in political philosophy and social order that emerged during this period in American history.
