Giordano Bruno was an Italian philosopher, burned at the stake in 1600 after being declared guilty of heresy by the Roman Inquisition, in consequence of his criticism of Christianity and the cosmological conclusions he had reached in his search for truth through philosophy. Bruno considered Christianity as a degenerative process that reached its climax during the Counter-Reformation, however what actually interests me is to expose briefly his cosmology, because it makes sense and is very similar to the vision of the cosmos that the Europeans had during Prehistory and Classical Antiquity.
According to Bruno the Universe is eternal (indeed for something to begin there must already be a space in which such a beginning can manifest itself) and infinitely extended (if it was spatially finite, in what would be contained? Remember that all that is spatially finite is inevitably 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, throughout Nature and, therefore, also in ourselves. For Bruno everything is matter, that is life, and the Universe consists in infinite matter that changes perennially, able to transform itself continuously in an incessant becoming, 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!
