Persistence of metaphysical problems.
This sense at once of the limits of science and of the infinity of human aspirations makes it forever inadmissible for man to abandon all effort to solve the great problem of the origin and destiny of the universe. The child, Spencer says, may hide his head under the bed-clothes, and for an instant escape consciousness of the darkness outside; but in the long run the consciousness subsists, the imagination continues to dwell upon what lies beyond the limits of human conception. The progress of human thought has consisted less in discovering answers to ultimate problems than in discovering more precise methods of formulating the problems themselves; the enigmas are no longer stated in primitive terms. This change in statement is a proof of the progress and growth in the human mind; but the problems unhappily are as difficult as ever to solve. Up to the present moment no sufficient answer has been suggested, the mystery has simply been transposed from one place to another; so much so that Spencer says the scientific interpretation of the universe is as full of mysteries as theology; and he compares human knowledge to a luminous globe in the midst of infinite darkness. The larger the globe becomes the greater the depth and extent of darkness that it reveals, insomuch that increase of science but enlarges the abyss of our ignorance.
Possible finiteness of the unknown.
One must, however, be on one’s guard against exaggeration. The universe is infinite, no doubt, and consequently the material of human science is infinite, but the universe is dominated by a certain number of simple laws with which we may become continuously better and better acquainted. Many generations of men would be necessary to master in all their complexity the vedic epics, but we are able even to-day to formulate the principles which dominate them, and it is not impossible that we may some day be able to do the same for the epic of the universe. We may be able even to go the length of achieving precision in our ignorance, of marking in the infinite chain of phenomena the links which must forever be hidden from us. It is not accurate, therefore, to say that our ignorance increases with our knowledge, although it may be considered as probable that our knowledge will always be aware of something that escapes it, and may come in time to be able more and more distinctly to define, however negatively, the nature of this residuum. The infinity of the unknowable, even, is no more than hypothetical. We perhaps flatter ourselves in the belief that we possess anything that is infinite—even ignorance. Perhaps the sphere of our knowledge is like the terrestrial globe, enveloped by but a thin atmosphere of the unknowable and unknown; perhaps there is no basis and foundation of the universe, just as there is no basis and foundation of the earth; perhaps the ultimate secret of things is the gravitation of phenomena. The unknown is the air we breathe, but it is perhaps no more infinite than the earth’s atmosphere, and one’s consciousness of an unknowable infinity can no more be regarded as the basis of knowledge than the atmosphere of the earth can be regarded as the foundation upon which the earth rests.[119]
Distinction between religion and metaphysics.
Unknowable or not, infinite or finite, the unknown will always be the object of metaphysical hypotheses. But is to admit the perpetuity of metaphysical hypotheses to admit the eternity of religion? The question involves an ambiguity of words. Spencer defines religious thought as that which deals with all that lies beyond the sphere of the senses, but that is precisely the field of philosophic thought; philosophy in its entirety, therefore, and not religion only, is included in Spencer’s definition. Nay more, science itself is in part included in Spencer’s definition, for science, which takes cognizance of everything within the reach of perception and reasoning, by that very fact undertakes to fix the limit of their power, and thus indirectly touches upon the field of the unknowable—if not to enter it, at least to outline it, and that itself constitutes a sort of negative acquaintance with it. Knowledge is essentially critical and self-critical. The eternity of philosophy and of science must, no doubt, be admitted; but the eternity of religion, as that word is usually understood, in nowise follows from that admission.
Spencer’s unknowable.
According to Spencer, the unknowable itself is not absolutely unknowable. Among the mysteries, which become more mysterious as they are more deeply reflected upon, there will remain, Spencer thinks, for man one absolute certitude—that he is in the presence of an infinite and eternal energy which is the source of all things. The formula of human certitude is open to discussion. The man of science is more inclined to believe in an infinite number of energies than in an infinite energy, in a sort of mechanical atomism, a subdivision of force ad infinitum rather than in monism. Moreover, no religion can stop with the bare affirmation of the existence of an eternal energy or infinity of energies. It must maintain the existence of some relation between these energies and human morality, between the direction of these energies and that of the moral impulse in mankind. But a relation of this sort is the last thing in the world that can be deduced from the doctrine of evolution. Hypotheses in regard to the matter may of course be devised, but, far from possessing a character of certitude, such hypotheses would rather, from the point of view of pure science, display a positive improbability. Human morality, if it be considered scientifically, is a question that concerns the struggle for existence and not a question that concerns the universe. What distinguishes the natural forces, with which science deals, from gods, is precisely that the former are indifferent to the morality or immorality of our lives. In spite of our increasing admiration for the complexity of the phenomena of the world, for the solidarity that obtains among them, for the latent or active life which animates all things, we have not yet demonstrably discovered in the world a single element of divinity. Science does not reveal to us a universe spontaneously labouring for the realization of what we call goodness: goodness is to be realized, if at all, only by our bending the world to our purposes, by enslaving the gods that we once adored, by replacing the reign of God by the reign of man.
