Where did humanist get their ideas?

Humanists drew their ideas primarily from the study of classical texts from Ancient Greece and Rome, emphasizing the importance of human experience, reason, and individualism. They were influenced by the Renaissance revival of classical learning, which encouraged a focus on secular subjects such as literature, philosophy, and history. Additionally, Humanism was shaped by contemporary social and political changes, including the rise of urban centers and the questioning of religious authority. This intellectual movement sought to reconcile classical thought with contemporary life, fostering a new appreciation for human potential and achievements.
