There is a second necessity to which the systematic opponents of the supernatural must make up their minds. They must affirm that the laws proclaimed by them as general laws, laws immanent and permanent in what they call nature, are in effect the essential laws of all nature, of the entire universe, and of all the beings whose seeds are there sown. They would have no right to reject absolutely facts as supernatural if they were not supernatural of necessity and everywhere; if, in short, they were anywhere in harmony with laws of nature other than the laws of this hardly perceptible corner of nature which is the residence of man. If the laws of our world are not universal and absolute, who will venture to affirm that they cannot be changed or suspended, even there where they reign? Is human science ready to maintain that the laws which she discovers from her infinitely small Observatory are in effect universal and absolute laws in every place where matter exists, and where life manifests itself, in the midst of space and of time? {138} Here it is that Christian Ignorance begins to take its place; it admits the unknown and the diverse in the universe--an unknown incommensurable, a diverse infinitely possible. I respect and admire science profoundly; I am as moved, I feel as proud as M. de Laplace could ever have been at the aspect of this sublime flight of the human intelligence, which marches with sure footing in space and across worlds, measures their distances, and knows how many years are required for the light of the nearest of the fixed stars to reach us, whereas the light of our own sun reaches us in a few minutes. I am not less touched by the labours and the discoveries of the great modern Physiologists, who, walking in the footsteps of Bichat, observe and note, even in their minutest and most obscure details, the different phenomena which life in the midst of matter presents. But when I have rendered homage to these triumphs of human science, I compare them with the reality of things, with this universe infinitely great and infinitely minute, which man makes his study, and I cannot prevent the reflection, that the universe contains infinitely more objects than man's mind attains to, and infinitely more secrets than it discovers. {139} What astronomer will dare to affirm that he has counted all the worlds, and that his eye has reached the point beyond which no more exist? What physiologist, what naturalist, will affirm that all those worlds have living inhabitants? and that, if so, those inhabitants must have the same form, and be subject to the same conditions and laws, as govern the inhabitants of this globe. Our science becomes very modest when set side by side with our ignorance, even in the matters appropriate to science; and, however extensive and various the conquests of the human mind may be, the universe is infinitely vaster and more varied than is either the genius or the strength of its vain conqueror.
