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
