ment of matter and motion as to produce a diminished adaptation of means to ends. With the change from heterogeneity to homogeneity, the parts become less and less definite and coherent. If these abstract terms of general evolution be converted into the concrete terms of social evolution, we get a scientific conception of Lord Salisbury's taking phrase. A growing society is one where the population is increasing in numbers, and each individual finds the conditions of existence constantly bettered. The simple relations of primitive life are changed into the complex relations of civilized life. All the social organs required to meet every want and taste spring into existence. Instead of being limited to plunder, or the chase, or pastoral pursuits, human activity assumes the countless forms of modern industry. But while society is thus becoming more heterogeneous, its parts are becoming more definite and coherent. To increase the efficiency of their labor, people devote themselves to some particular pursuit. At the same time they become to an increasing degree dependent upon one another; for, in order to get what they want, they must exchange with one another the products of their toil. Where evolution is thus permitted to operate freely, the most perfect adaptation of society to the conditions of existence takes place, and the greatest possible degree of happiness is attained. In a decadent society this process is reversed. Because of the tyranny of custom, which forbids social change and adaptation, or in consequence of the Government's usurpation of functions that do not belong to it, which has the same fatal effect, people cease to be free to do as they please, and to live the life that seems to them best. Robbed by the crushing taxation necessary to sustain the bureaucratic parasites that enforce the rules and regulations throttling industry, they become discouraged, and, abandoning the honest pursuits of peace, they become beggars or brigands. Under these conditions, society becomes disorganized, and eventually disappears. As in Mesopotamia and other parts of Asia, once rich and populous, the country reverts to solitude.
We are now in a position to see that modern societies are not in a condition that permits of Lord Salisbury's easy classification. Decadent as some of them are in many respects, it is by no means certain that they have reached the limits of evolution and entered upon a career of dissolution. Evolving with great rapidity as others are, it is by no means certain that they are not pursuing a course that will bring them to ruin, Turkey is probably the most decadent of all. But it is not because of her loss of territory; it is because of her rigid social structure, her incapacity to adopt the ideas and institutions of progressive societies, and her failure to protect her people from the rapacity of officials and brigands. Although less militant, China suffers in a like manner. Besides the tyranny of custom, which represses the activity of the individual and thwarts social evolution, there is the tyranny of a powerful and corrupt bureaucracy. In consequence of both, ideas and institutions are antiquated, industry is in a primitive state, and the rewards of toil are very small. Nevertheless there are signs of growth. Railroads and telegraphs are being introduced, quickening the circulation of products and ideas. A movement is afoot to improve industrial methods and the administration of the government. Compared with Turkey and China, Spain is a progressive state. Within the last century
