"The Pythagoreans made kindness to beasts a training in humanity and pity."

“Porphyry, On the Cave of Nymphs, translated by Thomas Taylor”

“So people should abstain from other animals just as they should from the human.”

“Every body is in place; but nothing essentially incorporeal, or any thing of this kind, has any locality.”

“Incorporeal hypostases, in descending, are distributed into parts, and multiplied about individuals with a diminution of power; but when they ascend by their energies beyond bodies, they become united, and proceed into a simultaneous subsistence, through exuberance of power.”
