—With his last breath it becomes to each the same thing as though he had never lived? To the individual, perhaps—surely not to the humanity made wiser and better by his labors.... But the world must pass away: will it thereafter be the same for the universe as if humanity had never existed? That might depend upon the possibilities of future inter-planetary communication.... But the whole universe of suns and planets must also perish: thereafter will it be the same as if no intelligent life had ever toiled and suffered upon those countless worlds? We have at least the certainty that the energies of life cannot be destroyed, and the strong probability that they will help to form another life and thought in universes yet to be evolved.... Nevertheless, allowing for all imagined possibilities,—granting even the likelihood of some inapprehensible relation between all past and all future conditioned-being,—the tremendous question remains: What signifies the whole of apparitional existence to the Unconditioned? As flickers of sheet-lightning leave no record in the night, so in that Darkness a million billion trillion universes might come and go, and leave no trace of their having been.
To every aspect of the problem Herbert Spencer must have given thought; but he has plainly declared that the human intellect, as at present constituted, can offer no solution. The greatest mind that this world has yet produced—the mind that systematized all human knowledge, that revolutionized modern science, that dissipated materialism forever, that revealed to us the ghostly unity of all existence, that reestablished all ethics upon an immutable and eternal foundation,—the mind that could expound with equal lucidity, and by the same universal formula, the history of a gnat or the history of a sun—confessed itself, before the Riddle of Existence, scarcely less helpless than the mind of a child.
But for me the supreme value of this last essay is made by the fact that in its pathetic statement of uncertainties and probabilities one can discern something very much resembling a declaration of faith. Though assured that we have yet no foundation for any belief in the persistence of consciousness after the death of the brain, we are bidden to remember that the ultimate nature of consciousness remains inscrutable. Though we cannot surmise the relation of consciousness to the unseen, we are reminded that it must be considered as a manifestation of the Infinite Energy, and that its elements, if dissociated by death, will return to the timeless and measureless Source of Life.... Science to-day also assures us that whatever existence has been—all individual life that ever moved in animal or plant,—all feeling and thought that ever stirred in human consciousness—must have flashed self-record beyond the sphere of sentiency; and though we cannot know, we cannot help imagining that the best of such registration may be destined to perpetuity. On this latter subject, for obvious reasons, Herbert Spencer has remained silent; but the reader may ponder a remarkable paragraph in the final sixth edition of the "First Principles,"—a paragraph dealing with the hypothesis that consciousness may belong to the cosmic ether. This hypothesis has not been lightly dismissed by him; and even while proving its inadequacy, he seems to intimate that it may represent imperfectly some truth yet inapprehensible by the human mind:—
"The only supposition having consistency is that that in which consciousness inheres is the all-pervading ether. This we know can be affected by molecules of matter in motion, and conversely can affect the motions of molecules;—as witness the action of light on the retina. In pursuance of this supposition we may assume that the ether, which pervades not only all space but all matter, is, under special conditions in certain parts of the nervous system, capable of being affected by the nervous changes in such way as to result in feeling, and is reciprocally capable under these conditions of affecting the nervous changes. But if we accept this explanation, we must assume that the potentiality of feeling is universal, and that the evolution of feeling in the ether takes place only under the extremely complex conditions occurring in certain nervous centres. This, however, is but a semblance of an explanation, since we know not what the ether is, and since, by confession of those most capable of judging, no hypothesis that has been framed accounts for all its powers. Such an explanation may be said to do no more than symbolize the phenomena by symbols of unknown natures."—["First Principles," § 71 c, definitive edition of 1900.]
—"Inscrutable is this complex consciousness which has slowly evolved out of infantine vacuity—consciousness which, in other shapes, is manifested by animate beings at large—consciousness which, during the development of every creature, makes its appearance out of what seems unconscious matter; suggesting the thought that consciousness, in some rudimentary form, is omnipresent."[65]
—Of all modern thinkers, Spencer was perhaps the most careful to avoid giving encouragement to any hypothesis unsupported by powerful evidence. Even the simple sum of his own creed is uttered only, with due reservation, as a statement of three probabilities: that consciousness represents a specialized and individualized form of the infinite Energy; that it is dissolved by death; and that its elements then return to the source of all being. As for our mental attitude toward the infinite Mystery, his advice is plain. We must resign ourselves to the eternal law, and endeavor to vanquish our ancient inheritance of superstitious terrors, remembering that, "merciless as is the Cosmic process worked out by an Unknown Power, yet vengeance is nowhere to be found in it."[66]
In the same brief essay there is another confession of singular interest,—an acknowledgment of the terror of Space. To even the ordinary mind, the notion of infinite Space, as forced upon us by those monstrous facts of astronomy which require no serious study to apprehend, is terrifying;—I mean the mere vague idea of that everlasting Night into which the blazing of millions of suns can bring neither light nor warmth. But to the intellect of Herbert Spencer the idea of Space must have presented itself after a manner incomparably more mysterious and stupendous. The mathematician alone will comprehend the full significance of the paragraph dealing with the Geometry of Position and the mystery of space-relations,—or the startling declaration that "even could we penetrate the mysteries of existence, there would remain still more transcendent mysteries." But Herbert Spencer tells us that, apart from the conception of these geometrical mysteries, the problem of naked Space itself became for him, in the twilight of his age, an obsession and a dismay:—
... "And then comes the thought of this universal matrix itself, anteceding alike creation or evolution, whichever be assumed, and infinitely transcending both, alike in extent and duration; since both, if conceived at all, must be conceived as having had beginnings, while Space had no beginning. The thought of this blank form of existence which, explored in all directions as far as imagination can reach, has, beyond that, an unexplored region compared with which the part which imagination has traversed is but infinitesimal,—the thought of a Space compared with which our immeasurable sidereal system dwindles to a point is a thought too overwhelming to be dwelt upon. Of late years the consciousness that without origin or cause infinite Space has ever existed and must ever exist, produces in me a feeling from which I shrink."
