Why did Giordano Bruno publicly attack Aristotle in 1586?

In May 1586, Giordano Bruno publicly attacked Aristotle in his work Centum et viginti articuli de natura et mundo adversus Peripateticos ("120 Articles on Nature and the World Against the Peripatetics").1

This public challenge was part of a broader, ongoing polemic against the rigid Aristotelian and Scholastic principles that dominated the academic and religious institutions of his time. Bruno’s philosophy, which included the theory of an infinite universe and the multiplicity of worlds, stood in direct opposition to the traditional geocentric astronomy and physics supported by Aristotelian thought. By attacking the Peripatetics—the followers of Aristotle—Bruno sought to dismantle the intellectual framework that he believed hindered the pursuit of truth and the development of a more accurate understanding of nature.21

Following this provocative act, the Politiques disavowed him, and Bruno was forced to leave Paris.1
