Explorando o infinito: uma interpretação sobre o universo filosófico de Giordano Bruno

Abstract

This dissertation investigates the cosmological and ontological vision of Giordano Bruno (1548–1600) through the direct analysis of two of his works, De l'infinito, universo e mondi (1584a) and De la causa, principio et uno (1584b), both published in London in 1584. The central objective is to understand how Bruno articulates his description of the universe — infinite, without a fixed center, and inhabited by countless worlds — with his philosophical conception of the nature of God. The methodology adopted is qualitative, bibliographical and historical, grounded in the principles of Marc Bloch as set out in The Historian's Craft (1944), with emphasis on the direct analysis of primary sources in Italian and on the historical contextualization of Brunian thought, without anachronistic projections onto the past. Throughout the chapters, the research reconstructs the biographical, intellectual, and institutional context of Bruno in sixteenth-century Europe; systematically describes the structure and argumentation of the ten dialogues of the analyzed works; and develops a philosophical analysis of Bruno's model of the universe in his two books, organized into three parts: the Aristotelian-Ptolemaic model that Bruno rejects; the model he proposes, based on direct quotations from the texts; and a synthesis that articulates the elements of the system. The results show that the infinitude of the universe is, for Bruno, a necessary consequence of the infinite nature of God, and that each cosmological proposition finds its foundation in a corresponding ontological proposition. The dissertation contributes to expanding Brazilian academic production on Bruno and to the field of the history of science in the context of science and mathematics education.
