Giordano Bruno was an Italian philosopher, burned at the stake in 1600 after being declared guilty of heresy by the Roman Inquisition, in consequence to his criticism of Christianity and to the cosmological conclusions he had reached during his search for truth through philosophy. Bruno considered Christianity as a degenerative process that reached its culmination during the Counter-Reformation, however, what actually interests me is his cosmology, because it makes sense: I will describe it briefly.
According to Bruno the Universe is eternal (indeed, in order for something to have a beginning there must already be a space in which such a beginning can manifest itself) and infinitely extended (if instead it was spatially finite, in what would be contained? Keep in mind that all that is spatially finite must inevitably be contained in a larger space), whereby motionless and without a center. It is a unitary and vast living organism, animated and endowed with intellect, a homogeneous and indivisible whole governed by the interdependence of all its parts, which are in relation to the organism in its unity (i.e. an organism made up of organisms), unity that coincides with the concept of divinity: consequently the divine resides in the multiplicity that exists in the Universe, in every part of nature and, therefore, also in ourselves. For Bruno everything is matter, i.e. life, and the Universe consists in infinite matter that changes perennially, able to transform and renew itself continuously in an incessant becoming marked by cyclic rhythms, passing from one extreme to the other, from an opposite to the other. The universal matter is infinite energy provided with intellect, unity in which lies a multiplicity, multiplicity in which lies a unity!
