How did Gutenberg spread Renaissance ideas?

Gutenberg spread Renaissance ideas primarily through the invention of the printing press in the mid-15th century, which revolutionized the production of books. By making texts more accessible and affordable, his press facilitated the widespread dissemination of humanist literature, scientific works, and classical texts that were central to Renaissance thought. This democratization of knowledge encouraged literacy and critical thinking, allowing Renaissance ideas to reach a broader audience across Europe, ultimately influencing art, science, and culture.
