Based on the excerpt, how did the revival of classical texts during the Renaissance contribute to the development of humanism?

During the Renaissance, Europe underwent a dramatic transformation that redefined its cultural and intellectual identity. Classical ideas and texts were rediscovered, illuminating aspects of human experience that had been overshadowed during the Middle Ages. Humanism emerged as a cornerstone of this transformation, emphasizing the capacity for individual achievement and rational thought. Art, literature, and philosophy began to celebrate human potential in new and creative ways. These developments were deeply intertwined with the broader social and political changes of the era. The era set the stage for modern Western consciousness by blending innovative thought with artistic expression.
