These arguments possess a peculiar interest owing to the fact that they have not originated with socialistic thinkers at all, but have been drawn by them from the evolutionary philosophy of the nineteenth century generally, in so far as it was applied to historical and sociological questions. The dominant idea which distinguished this school of thought was the insignificance of the individual as compared with society past and present. Thus Herbert Spencer, who was its most systematic exponent, opens his work on the _Study of Sociology_ with an elaborate attack on what he calls "The Great Man Theory," according to which the explanation of the main events of history is to be sought in the influence of exceptional or great men--the men who, in vulgar language, are spoken of as "historical characters." Such an explanation, said Spencer, is no explanation at all. Great men, however great, are not isolated phenomena. Whatever they may do as the "proximate initiators" of change, they themselves "have their chief cause in the generations they have descended from," and depend for the influence which is commonly attributed to their actions, on "the multitudinous conditions" of the generation to which they belong. Thus Laplace, he says, could not have got far with his calculations if it had not been for the line of mathematicians who went before him. Caesar could not have got very far with his conquests if a great military organisation had not been ready to his hand; nor could Shakespeare have written his dramas if he had not lived in a country already enriched with traditions and a highly developed language. But though it was Herbert Spencer who invested these arguments with their most systematic form, and gave them their definite place in the theory of evolution as a whole, they were widely diffused already among his immediate predecessors, as we may see by the following passage taken from an unlikely quarter. "It is," says Macaulay, in his _Essay on Dryden_, anticipating the exact phraseology of Spencer, "the age that makes the man, not the man that makes the age.... The inequalities of the intellect, like the inequalities of the surface of the globe, bear so small a proportion to the mass, that in calculating its great revolutions they may safely be neglected." And Macaulay is merely expressing a doctrine distinctive of his time--a doctrine which, to take one further example, dominated in a notable way the entire thought of Buckle. This doctrine, which, to a greater or less degree, merges the organism in its environment, or the individual, however great, in society, has been seized on by the more recent socialists just as the theory of Ricardo, with regard to labour and value, was seized on by Karl Marx, and has been adapted by them to their own purposes.
