Giordano Bruno.
They nailed his ass for heresy.
Denial of Damnation and the Trinity.
Denial of the Virginity of Mary.
Denial of the Divinity of Jesus.
Denied Transubstantiation.
Said the soul could be transported into animals.
Believed in Astrology.
All in all, a normal modern Democrat.
Do not pass go, do not collect $200.
On the contrary, in addition to his cosmology which was largely a brilliantly imaginative but evidence-free fantasia, Bruno taught pantheism, the transmigration of souls (reincarnation), alchemy, astrology, a form of animism (communing with the spirits of metals, animals, stars, whatever) and aspired to be a magus/wizard in the Hermetic tradition.
In short, a religious charlatan and a scientific quack.
Just the kind of intellectual, I think, that Jorge Bergoglio might admire.
