In his book Dieta Naturalis, he said, "One should not vent one's wrath on animals, Theology decree that man has a soul and that the animals are mere 'aoutomata mechanica,' but I believe they would be better advised that animals have a soul and that the difference is of nobility."
No seu libro Dieta Naturalis dicía: Non se tería que descargar a ira sobre os animais; a teoloxía decreta que o home ten alma e que os animais son simples autómatas mecánicos, pero creo que sería mellor recomendar que os animais teñan alma e que a diferenza sexa a nobreza.
