Iconoclasts are individuals who challenge or reject established beliefs, traditions, or institutions. The term originally referred to those who opposed the veneration of religious icons in the Byzantine Empire. Over time, it has come to describe anyone who questions or dismantles widely accepted norms in various fields, including art, politics, and science. These thinkers often provoke change by introducing new ideas or perspectives that can lead to innovation and progress. Famous iconoclasts include figures like Galileo Galilei, who challenged the geocentric view of the universe, and Pablo Picasso, who revolutionized modern art with his unconventional styles.
