The great movement of modern thought, of which Bacon was at once the highest representative and one of the chief agents, has been truly said to exhibit a striking resemblance, and at the same time a striking contrast, to the movement of ancient thought, which was effected chiefly by the genius of Socrates. In the name of utility, Socrates diverted the intellect of antiquity from the fantastic cosmogonies with which it had long been occupied, to the study of the moral nature of man. In the name of the same utility Bacon laboured to divert the modern intellect from the idle metaphysical speculations of the schoolmen to natural science, to which newly discovered instruments of research, his own sounder method, and a cluster of splendid intellects, soon gave an unprecedented impulse. To the indirect influence of this movement, perhaps, even more than to the direct teaching of Gassendi and Locke, may be ascribed the great ascendency of sensational philosophy among modern nations, and it is also connected with some of the most important differences between ancient and modern history. Among the ancients the human mind was chiefly directed to philosophical speculations, in which the law seems to be perpetual oscillation, while among the moderns it has rather tended towards physical science, and towards inventions, in which the law is perpetual progress. National power, and in most cases even national independence, implied among the ancients the constant energy of high intellectual or moral qualities. When the heroism or the genius of the people had relaxed, when an enervating philosophy or the lassitude that often accompanies civilisation arrived, the whole edifice speedily tottered, the sceptre was transferred to another state, and the same history was elsewhere reproduced. A great nation bequeathed indeed to its successors works of transcendent beauty in art and literature, philosophies that could avail only when the mind had risen to their level, examples that might stimulate the heroism of an aspiring people, warnings that might sometimes arrest it on the path to ruin. But all these acted only through the mind. In modern times, on the other hand, if we put aside religious influences, the principal causes of the superiority of civilised men are to be found in inventions which when once discovered can never pass away, and the effects of which are in consequence in a great measure removed from the fluctuations of moral life. The causes which most disturbed or accelerated the normal progress of society in antiquity were the appearance of great men, in modern times they have been the appearance of great inventions. Printing has secured the intellectual achievements of the past, and furnished a sure guarantee of future progress. Gunpowder and military machinery have rendered the triumph of barbarians impossible. Steam has united nations in the closest bonds. Innumerable mechanical contrivances
