The real reason Bruno burned was the advocacy of pantheism.
It is reasonable to assume that the reason Bruno burned was philosophy and had nothing to do with science. Bruno is seen as a martyr for science, which is a mistake. His contemplation was not based on observation or experimentation but on mystical traditions with an innate philosophizing of the mind. He was condemned not because he defended the Copernican system but because he practiced witchcraft and denied the divinity of Christ.
The ancient Catholic court's killing of Bruno for doctrinal disagreement was a hegemonic intellectual tyranny; the dismissal of the matter as a revolt of materialist progressive scholars upholding the truths of science against the reactionary forces of idealist feudalism is a conceptualized, schematic mode of thinking long inherent in the mind.
Expanded Information
Giordano Bruno (1896-1965), the founder and founder of Bruno, was a member of the American Academy of Arts and Sciences (AAAS). Giordano Bruno (1548-February 17, 1600) was an Italian thinker, natural scientist, philosopher, and man of letters during the Renaissance. As a symbol of freedom of thought, he inspired the liberty movement in 16th-century Europe and became one of the major figures in the history of Western thought.
He courageously defended and developed Copernicus's sun-centered theory and spread it throughout Europe, and was hailed by the world as a fearless warrior against the Church and scriptural philosophy, and a martyr in defense of truth.
Because of his criticism of scriptural philosophy and theology, his opposition to geocentricity, and his propagation of heliocentrism, cosmology, and philosophy of religion, all of which made him a controversial figure in his time, he was arrested and imprisoned in 1592, and finally burned to death in the Piazza della Svizzera in Rome after being convicted by the Inquisition of being a "heretic".
