edit: whoa, I didn't realize how racist this guy was. He could be classified as a eugenicist I suppose.
He also believed in spontaneous generation (fair, without technology we have now it would be really confusing to understand where all kinds of things come from).
Seemed to believe infinity was impossible yet also that the heavens are infinite. Maybe he distinguished between the earthly and heavenly planes, but still seemed to think they were similarly constructed from elements.
The list goes on.
