Humanism primarily originated in which centuries?

Humanism primarily originated during the Renaissance period, which is typically identified with the 14th to 16th centuries, making the 1400-1500 timeframe a significant era for the development of humanist thought. This movement emphasized the importance of classical texts, the value of human potential and achievements, and a shift towards secular subjects, markedly impacting art, science, and education.

By the 15th century, humanism was characterized by a resurgence of interest in the literature and philosophy of ancient Greece and Rome, leading to notable works from figures like Erasmus and Thomas More. This period laid the groundwork for many ideas that shaped modern Western thought, aligning closely with the correct answer indicating the time frame when humanism was most influential. The subsequent centuries, such as 1500-1600 and 1600-1700, were indeed marked by the continuation of humanist ideas but did not witness its inception and initial development as powerfully as the 1400-1500 century did.
