natural differences;" and, says Mr Buckle, "we cannot safely assume that there has been any permanent improvement in the moral or intellectual faculties of man, nor have we any decisive ground for saying that those faculties are likely to be greater in an infant born in the most civilized part of Europe, than in one born in the wildest region of a barbarous country."

Whether or not the nervous system, which is the connective tissue between man's animality and his intellectuality, transmits its subtle forces from one generation to another, we may be sure that the mind acts on the nerves, and the nerves on every part of the system, and that the intelligence of the mind influences and governs the materialism of the body, and the consequences in some way are felt by succeeding generations; but that the mind becomes material, and its qualities transmitted to posterity, is an hypothesis yet unestablished.

IMPROVE­MENT PURELY INTEL­LECTUAL.

Moreover we may safely conclude that the improvement of mankind is a phenomenon purely intellectual.

Not that the improvement of the mind is wholly independent of the condition of the body; for, as we shall hereafter see, so intimate is the connection between the mind and the body, that the first step toward intellectual advancement cannot be taken until the demands of the body are satisfied. Nervous phenomena are dependent upon the same nutritive processes that govern physical development; and that this nerve force, through whose agency the system is charged with intellectuality, as the molecule is charged with mechanical force, does exist, is capable, to some extent, of transmitting acquirements or artificial instincts from parent to child, we have every reason to believe; but, so far as we know, intellectual force, per se, is no more a transmittable entity than is the flesh-quivering of the slain ox life.

The strangest part of it all is, that though wrought out by man as the instrument, and while acting in the capacity of a free agent, this spirit of progress is wholly independent of the will of man. Though in our individual actions we imagine ourselves directed only by our free will, yet in the end it is most difficult to determine what is the result of free will, and what of inexorable environment. While we think we are regulating our affairs, our affairs are regulating us. We plan out improvements, predetermine the best course and follow it, sometimes; yet, for all that, the principle of social progress is not the man, is not in the man, forms no constituent of his physical or psychical individual being; it is the social atmosphere into which the man is born, into which he brings nothing and from which he takes nothing. While a member of society he adds his quota to the general fund and there leaves it; while acting as a free agent he performs his part in working out this problem of social development, performs it unconsciously, willing or unwilling he performs it, his baser passions being as powerful instruments of progress as his nobler; for avarice drives on intellect as effectually as benevolence, hate as love, and selfishness does infinitely more for the progress of mankind than philanthropy. Thus is humanity played upon by this principle of progress, and the music sometimes is wonderful; green fields as if by magic take the place of wild forests, magnificent cities rise out of the ground, the forces of nature are brought under the dominion of man's intelligence, and senseless substances endowed with speech and action.

It is verily as Carlyle says; "under the strangest new vesture, the old great truth (since no vesture can hide it) begins again to be revealed: That man is what we call a miraculous creature, with miraculous power over men; and, on the whole, with such a Life in him, and such a World round him, as victorious Analysis, with her Physiologies, Nervous Systems, Physic and Metaphysic, will never completely name, to say nothing of explaining."

Thus, to sum up the foregoing premises: in society, between two or more individuals, there is at work a mysterious energy, not unlike that of force between molecules or life in the organism; this social energy is under intelligent governance, not fortuitous nor causeless, but reducible to fixed law, and capable of being wrought into a science; is, moreover, a vital actuality, not an incident nor an accident, but an entity, as attraction and repulsion are entities; under this agency society, perforce, develops like the plant from a germ. This energy acts on the intellect, and through the intellect on the organism; acts independently of the will, and cannot be created or destroyed by man; is not found in the brute creation, is not transmittable by generation through individuals, is wrought out by man as a free-will agent, though acting unconsciously, and is the product alike of good and evil.

CAUSES OF MAN'S DEVELOP­MENT.

As to the causes which originate progressional phenomena there are differences of opinion. One sees in the intellect the germ of an eternal unfolding; another recognizes in the soul-element the vital principle of progress, and attributes to religion all the benefits of enlightenment; one builds a theory on the ground-work of a fundamental and innate morality; another discovers in the forces of nature the controlling influence upon man's destiny; while yet others, as we have seen, believe accumulative and inherent nervous force to be the media through which culture is transmitted. Some believe that moral causes create the physical, others that physical causes create the moral.

Thus Mr Buckle attempts to prove that man's development is wholly dependent upon his physical surroundings. Huxley points to a system of reflex actions,—mind acting on matter, and matter on mind,—as the possible culture-basis. Darwin advances the doctrine of an evolution from vivified matter as the principle of progressive development. In the transmution of nerve-element from parents to children, Bagehot sees "the continuous force which binds age to age, which enables each to begin with some improvement on the last, if the last did itself improve; which makes each civilization not a set of detached dots, but a line of color, surely enhancing shade by shade." Some see in human progress the ever-ruling hand of a divine providence, others the results of man's skill; with some it is free will, with others necessity; some believe that intellectual development springs from better systems of government, others that wealth lies at the foundation of all culture; every philosopher recognizes some cause, invents some system, or brings human actions under the dominion of some species of law.

As in animals of the same genus or species, inhabiting widely different localities, we see the results of common instincts, so in the evolutions of the human race, divided by time or space, we see the same general principles at work. So too it would seem, whether species are one or many, whether man is a perfectly created being or an evolution from a lower form, that all the human races of the globe are formed on one model and governed by the same laws. In the customs, languages, and myths of ages and nations far removed from each other in social, moral, and mental characteristics, innumerable and striking analogies exist. Not only have all nations weapons, but many who are separated from each other by a hemisphere use the same weapon; not only is belief universal, but many relate the same myth; and to suppose the bow and arrow to have had a common origin, or that all flood-myths, and myths of a future life are but offshoots from Noachic and Biblical narratives is scarcely reasonable.
