15. As to miracles, properly speaking, nothing being impossible with God, he can perform them without doubt. Has he done it? Does he ever act contrary to the laws which he has established? It does not belong to man to prejudge the acts of divinity, and to subordinate them to the feebleness of his understanding. However, we have for criterion of our judgment, in regard to divine things, the attributes even of God. To sovereign power he joins sovereign wisdom, whence it is necessary to conclude that he does nothing uselessly.
Why then should he perform miracles? In order to attest his power, it is said. But the power of God, is it not manifested in a much more striking manner by the magnificent whole of the works of creation, by the foreseeing wisdom which presides in the smallest as well as the largest of his works, and by the harmony of the laws which rule the universe, than by a few little and puerile modification which all tricksters know how to imitate? What would we think of a learned mechanic who, in order to prove his skill, should disarrange the clock which he had constructed, a masterpiece of scientific skill, in order to prove that he can deface that which he has made? On the contrary, is his knowledge not displayed by the regularity and precision of its movements?
The question of miracles, then, is not, properly speaking, in the province of Spiritism; but, sustaining itself by the reasoning that God makes nothing uselessly, this idea can be educed: that, miracles not being necessary to the glorification of God, nothing in the universe is diverted from the general laws. God does not perform miracles; since his laws are perfect, he has no need to derogate them. If there are some facts which we do not understand, it is because we have not the necessary knowledge to comprehend them.
