 Furthermore, if the animals are capable of knowing the world through sensory perception, nature would have been very cruel for making them suffer all they suffer, for example, at the hands of men. And, given that certain species of animals can pre-empt the arrival of cold winter and shelter or run away from it, we must grant them also some faculty of prediction; but, if they can predict the winter, they will also be able to have knowledge of death and, just like human beings, they will worry about the future of their souls (AM: 1.215).
