Görres taught, reasonably enough, I conceive, in his _Mystik_, that there is a physical basis for the great mass of miracles wrought by Almighty God in and through his saints; that is to say, that they do not, ordinarily speaking, involve the creation of an entirely fresh power, but are rather the result of a divine excitation of a power already existing in germ. Of course, he who "of these stones can raise up children to Abraham" only subjects himself to the laws which he has made in so far as it pleases him to do so; and the scholastics were right in their insistence upon what they called the "obediential" power of things--that is, their inherent capacity of becoming anything in the hands of their Creator. Of course, too, it is often impossible to ascertain in a given case whether God is using that _altum dominium_ which he possesses as Creator, or, on the other hand, is merely developing previously existing powers. Everything tends to persuade us that all nature, and especially the human soul, is full of rudimental powers which may be developed, 1st, by the special, immediate action of the Creator; 2d, by spiritual influences, good and bad; 3d, by certain abnormal conditions of the bodily organism. I conceive that these rudimental powers form a common natural basis for the great mass of both divine and diabolic miracles, and that sometimes they may attain to a considerable degree of development without any special influence, divine or diabolic. The existence of such a common basis would seem to be implied in the fact that the devil has been able to imitate successfully and really, as in the case of Pharao's magicians, so many of the divine miracles; for we know that he can at most develop what already exists, without having the least power to create what is not. We cannot imagine that God would ever create where he might develop, according to the scholastic principle which Sir William Hamilton has translated into the Law of Parsimony: _Deus non abundat in superfluis_. To take a particular example, Görres maintains that the ascetic and mystic process which the mind of the saint goes through by abstraction from earthly things, and the habit of celestial contemplation, does really co-operate in the phenomenon, so common in ecstasy, of levitation. In which case, the saint would be rather aided by God, acting upon his body through his soul, to rise in the air, than, properly speaking, lifted up by him. This levitation is common enough in the best authenticated cases of diabolical possession; and, if it does not occur in cases presumably natural, at least a wholly abnormal lightness and agility is not unfrequent in some of the movements of somnambulism. We find an example of this in the following narrative, taken from a rare treatise of the Benedictine Abbot Trithemius (sæc. 15), entitled _Curiositas Regia_ (p. 29): "Let any one who knows nothing of nature tell me if the specific gravity of the body can be lightened by the action of the mind.
