What does Giordano Bruno’s idea of the unity of matter and form mean?

In his work Concerning the Cause, Principle, and One, Giordano Bruno proposed that "form" and "matter" are intimately united, together constituting a single entity. This concept served to challenge the traditional dualism found in Aristotelian physics.1

By reducing this dualism to a monistic conception of the world, Bruno argued for the basic unity of all substances and the coincidence of opposites within the infinite unity of Being. This perspective was central to his broader philosophical framework, which posited that the universe is an infinite, unified whole.12
