He held no favor for Protestantism, which was in its early formative stages. Bruno travelled widely, returned to Italy, was imprisoned for his heresy, and burned at the stake in Rome in 1600. According to Bruno the universe is infinite and is full of a plurality of heliocentric systems, which are composed of matter and soul. Both matter and soul are, rather than principles, two aspects of a single substance in which all opposites and all differences are reconciled. Religion has a practical but not a theoretical value.
Morality is the participation of the individual in the life of the universe.
To identify God and Nature was not a negation but an explanation. This construction led to Bruno's condemnation. Bruno's philosophy is a theoretical expression of Humanism, and its influence on subsequent thought was great. His thinking influenced Leibnitz and Hegel. According to Campanella to know means to feel, and to feel means to take notice of sensitive modifications.
