"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.”

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