 We might also grant them the knowledge of universal concepts. As Aristotle says, once the premises are established and known, it is necessary to deduce from them a conclusion: for example, if beasts know that this fire burns, and that this other also burns, and they run away from whatever fire they can perceive, they must have formulated the proposition “all fire burns.” In this case, they have an indivisible soul, since only with an indivisible soul can one achieve the knowledge of any object as a whole. For, if we accept that the animals have a divisible soul (quanta), they will never reach such global knowledge: an animal would know through a part of it a part of its object, and through another, another part, and so it would be unable to reach a perfect identification of whatever could be in front of it (AM: I.227).
