Unspeakably momentous, however, we once more admit, the discovery is, and great is the debt of gratitude due to its illustrious authors. Yet it seems not unreasonable to ask whether in some respects we are not too much under its immediate influence, and whether the revolution of thought, though destined ultimately to be vast, may not at present have somewhat overpassed its bounds. Is it not possible that the physical origin of man may be just now occupying too large a space in our minds compared with his ulterior development and his final destiny? With our eyes fixed on the "Descent," newly disclosed to us, may we not be losing sight of the Ascent of man?
There seems in the first place, to be a tendency to treat the origin of a being as finally decisive of its nature and destiny. From the language sometimes used, we should almost suppose that rudiments alone were real, and that all the rest was mere illusion. An eminent writer on the antiquities of jurisprudence intimates his belief that the idea of human brotherhood is not coeval with the race, and that primitive communities were governed by sentiments of a very different kind. His words are at once pounced upon as a warrant for dismissing the idea of human brotherhood from our minds, and substituting for it some other social principles, the character of which has not yet been definitely explained, though it is beginning in some quarters pretty distinctly to appear. But surely this is not reasonable. There can be no reason why the first estate of man, which all allow to have been his lowest estate, should claim the prerogative of furnishing his only real and indefeasible principles of action. Granting that the idea of human brotherhood was not aboriginal—granting that it came into the world at a comparatively late period, still it has come, and having come, it is as real and seems as much entitled to consideration as inter-tribal hostility and domestic despotism were in their own day. That its advent has not been unattended by illusions and aberrations is a fact which does not cancel its title to real existence under the present conditions, and with the present lights of society, any more than in annuls the great effects upon the actions of men and the course of history which the idea has undeniably produced. Human brotherhood was not a part of a primaeval revelation; it may not have been an original institution; but it seems to be a real part of a development, and it may be a part of a plan. That the social principles of certain anti- philanthropic works are identical with those which governed the actions of mankind in a primaeval and rudimentary state, when man had only just emerged from the animal, and have been since worked off by the foremost races in the course of development, is surely rather an argument against the paramount and indefeasible authority of those principles than in favour of it. It tends rather to show that their real character is that of a relapse, or, as the physiologists call it, a reversion. When there is a vast increase of wealth, of sensual enjoyment, and of the selfishness which is apt to attend them, it is not marvellous that such reversions should occur.
Another eminent writer appears to think that he has put an end to metaphysical theology, and perhaps to metaphysics and theology altogether, by showing that "being," and the cognate words, originally denoted merely physical perceptions. But so, probably, did all language. So did "spirit," so did "geist," so did "power," so did even "sweet reasonableness," and "the not us which makes for righteousness." Other perceptions or ideas have gradually come, and are now denoted by the words which at first denoted physical perceptions only. Why have not these last comers as good a claim to existence as the first? Suppose the intellectual nature of man has unfolded, and been brought, as it conceivably may, into relations with something in the universe beyond the mere indications of the five bodily senses—why are we bound to mistrust the results of this unfolding? We might go still further back, and still lower, than to language denoting merely physical perceptions. We might go back to inarticulate sounds and signs; but this does not invalidate the reality of the perceptions afterwards expressed in articulate language. It seems not very easy to distinguish, in point of trustworthiness of source, between the principles of metaphysics and the first principles of mathematics, or to say, if we accept the deductions in one case, why we should not accept them in the other. It is conceivable at least, we venture to repeat, that the development of man's intellectual nature may have enabled him to perceive other things than those which he perceives by means of his five bodily senses; and metaphysics, once non-existent, may thus have come into legitimate existence. Man, if the doctrine of evolution is true, was once a creature with only bodily senses; nay, at a still earlier stage, he was matter devoid even of bodily sense; now he has arrived—through the exercise of his bodily senses it may be—at something beyond bodily sense, at such notions as being, essence, existence: he reasons upon these notions, and extends the scope of his once merely physical vocabulary so as to comprehend them. Why should he not? If we are to be anchored hard and fast to the signification of primaeval language, how are we to obtain an intellectual basis for "the not us which makes for righteousness?" Do not the anti-metaphysicists themselves unconsciously metaphysicize? Does not their fundamental assumption—that the knowledge received through our bodily senses alone is trustworthy—involve an appeal to a mental necessity as much as anything in metaphysics, whether the mental necessity in this case be real or not?
Again, the great author of the Evolution theory himself, in his Descent of Man, has given us an account of morality which suggests a remark of the same kind. He seems to have come to the conclusion that what is called our moral sense is merely an indication of the superior permanency of social compared with personal impressions. Morality, if we take his explanation as complete and final, is reduced to tribal self-preservation subtilized into etiquette; an etiquette which, perhaps, a sceptical voluptuary, wishing to remove the obstacles to a life of enjoyment, might think himself not unreasonable in treating as an illusion. This, so far as appears, is the explanation offered of moral life, with all its beauty, its tenderness, its heroism, its self- sacrifice; to say nothing of spiritual life with its hopes and aspirations, its prayers and fanes. Such an account even of the origin of morality seems rather difficult to receive. Surely, even in their most rudimentary condition, virtue and vice must have been distinguished by some other characteristic than the relative permanency of two different sets of impressions. There is a tendency, we may venture to observe, on the part of eminent physicists, when they have carefully investigated and explained what seems to them the most important and substantial subjects of inquiry, to proffer less careful explanations of matters which to them seem secondary and less substantial, though possibly to an intelligence surveying the drama of the world from without the distinctly human portion of it might appear more important than the rest. Eminent physicists have been known, we believe, to account summarily for religion as a surviving reminiscence of the serpent which attacked the ancestral ape and the tree which sheltered him from the attack, so that Newton's religious belief would be a concomitant of his remaining trace of a tail. It was assumed that primaeval religion was universally the worship of the serpent and of the tree. This assumption was far from being correct; but, even if it had been correct, the theory based on it would surely have been a very summary account of the phenomena of religious life.
However, supposing the account of the origin of the moral sense and of moral life, given in The Descent of Man, to be true, it is an account of the origin only. Though profoundly significant, as well as profoundly interesting, it is not more significant, compared with the subsequent development, than is the origin of physical life compared with the subsequent history of living beings. Suppose a mineralogist or a chemist were to succeed in discovering the exact point at which inorganic matter gave birth to the organic; his discovery would be momentous and would convey to us a most distinct assurance of the method by which the governing power of the universe works: but would it qualify the mineralogist or the chemist to give a full account of all the diversities of animal life, and of the history of man? Heroism, self- sacrifice, the sense of moral beauty, the refined affections of civilized men, philanthropy, the desire of realizing a high moral ideal, whatever else they may be, are not tribal self-preservation subtilized into etiquette; nor are they adequately explained by reference to the permanent character of one set of impressions and the occasional character of another set. Between the origin of moral life and its present manifestation has intervened something so considerable as to baffle any anticipation of the destiny of humanity which could have been formed for a mere inspection of the rudiments. We may call this intervening force circumstance, if we please, provided we remember that calling it circumstance does not settle its nature, or exclude the existence of a power acting through circumstance as the method of fulfilling a design.
Whatever things may have been in their origin, they are what they are, both in themselves and in regard to their indications respecting other beings or influences the existence of which may be implied in theirs. The connection between the embryo and the adult man, with his moral sense and intelligence, and all that these imply, is manifest, as well as the gradual evolution of the one out of the other, and a conclusive argument is hence derived against certain superstitions or fantastic beliefs; but the embryo is not a man, neither is the man an embryo. A physiologist sets before us a set of plates showing the similarity between the embryo of Newton and that of his dog Diamond. The inference which he probably expects us to draw is that there is no essential difference between the philosopher and the dog. But surely it is at least as logical to infer, that the importance of the embryo and the significance of embryological similarities may not be so great as the physiologist is disposed to believe.
So with regard to human institutions. The writer on legal antiquities before mentioned finds two sets of institutions which are now directly opposed to each other, and between the respective advocates of which a controversy has been waged. He proposes to terminate that controversy by showing that though the two rival systems in their development are so different, in their origin they were the same. This seems very clearly to bring home to us the fact that, important as the results of an investigation of origins are, there is still a limit to their importance.
Again, while we allow no prejudice to stand in the way of our acceptance of Evolution, we may fairly call upon Evolution to be true to itself. We may call upon it to recognise the possibility of development in the future as well as the fact of development in the past, and not to shut up the hopes and aspirations of our race in a mundane egg because the mundane egg happens to be the special province of the physiologist. The series of developments has proceeded from the inorganic to the organic, from the organic upwards to moral and intellectual life. Why should it be arrested there? Why should it not continue its upward course and arrive at a development which might be designated as spiritual life? Surely the presumption is in favour of a continued operation of the law. Nothing can be more arbitrary than the proceeding of Comte, who, after tracing humanity, as he thinks, through the Theological and Metaphysical stages into the Positive, there closes the series and assumes that the Positive stage is absolutely final. How can he be sure that it will not be followed, for example, by one in which man will apprehend and commune with the Ruler of the Universe, not through mythology or dogma, but through Science? He may have had no experience of such a phase of human existence, nor may he be able at present distinctly to conceive it. But had he lived in the Theological or the Metaphysical era he would have been equally without experience of the Positive, and have had the same difficulty in conceiving its existence. His finality is an assumption apparently without foundation.
By Spiritual Life we do not mean the life of a disembodied spirit, or anything supernatural and anti-scientific, but a life the motives of which are beyond the world of sense, and the aim of which is an ideal, individual and collective, which may be approached but cannot be attained under our present conditions, and the conception of which involves the hope of an ulterior and better state. The Positivists themselves often use the word "spiritual," and it may be assumed that they mean by it something higher in the way of aspiration than what is denoted by the mere term moral, though they may not look forward to any other state of being than this.
We do not presume, of course, in these few pages to broach any great question, our only purpose being to point out a possible aberration or exaggeration of the prevailing school of thought. But it must surely be apparent to the moral philosopher, no less than to the student of history, that at the time of the appearance of Christianity, a crisis took place in the development of humanity which may be not unfitly described as the commencement of Spiritual Life. The change was not abrupt. It had been preceded and heralded by the increasing spirituality of the Hebrew religion, especially in the teachings of the prophets, by the spiritualization of Greek philosophy, and perhaps by the sublimation of Roman duty; but it was critical and decided. So much is admitted even by those who deplore the advent of Christianity as a fatal historical catastrophe, which turned away men's minds from the improvement of their material condition to the pursuit of a chimerical ideal. Faith, Hope, and Charity, by which the Gospel designates the triple manifestation of spiritual life, are new names for new things; for it is needless to say that in classical Greek the words have nothing like their Gospel signification. It would be difficult, we believe, to find in any Greek or Roman writer an expression of hope for the future of humanity. The nearest approach to such a sentiment, perhaps, is in the political Utopianism of Plato. The social ideal is placed in a golden age which has irretrievably passed away. Virgil's Fourth Eclogue, even if it were a more serious production than it is, seems to refer to nothing more than the pacification of the Roman Empire and the restoration of its material prosperity by Augustus. But Christianity, in the Apocalypse, at once breaks forth into a confident prediction of the ultimate triumph of good over evil, and of the realization of the ideal.
