But the theologians say: No, this is not so. Though man has powers and outer senses in common with the animal, yet an extraordinary power exists in him of which the animal is bereft. The sciences, arts, inventions, trades, and discoveries of realities, are the results of this spiritual power. This is a power which encompasses all things, comprehends their realities, discovers all the hidden mysteries of beings, and through this knowledge controls them: it even perceives things which do not exist outwardly; that is to say, intellectual realities which are not sensible, and which have no outward existence, because they are invisible; so it comprehends the mind, the spirit, the qualities, the characters, the love and sorrow of man, which are intellectual realities. Moreover, these existing sciences, arts, laws, and endless inventions of man at one time were invisible, mysterious, and hidden secrets; it is only the all-encompassing human power which has discovered and brought them out from the plane of the invisible to the plane of the visible. So telegraphy, photography, phonography, and all such inventions and wonderful arts, were at one time hidden mysteries: the human reality discovered and brought them out from the plane of the invisible to the plane of the visible. There was even a time when the qualities of this iron which you see—indeed of all the metals—were hidden mysteries; men discovered this metal, and wrought it in this industrial form. It is the same with all the other discoveries and inventions of man, which are innumerable. This we cannot deny. If we say that these are effects of powers which animals also have, and of the powers of the bodily senses, we see clearly and evidently that the animals are, in regard to these powers, superior to man. For example, the sight of animals is much more keen than the sight of man; so also is their power of smell and taste. Briefly, in the powers which animals and men have in common, the animal is often the more powerful. For example, let us take the power of memory: if you carry a pigeon from here to a distant country, and there set it free, it will return, for it remembers the way. Take a dog from here to the center of Asia, set him free, and he will come back here and never once lose the road. So it is with the other powers such as hearing, sight, smell, taste, and touch.
