And yet, on the very next page, he closes this essay with a note of the serenest optimism:
"So far, we all may strive in one faith towards one hope."[219] And the keynote of his attitude towards this subject is to be found in a passage in which he "thinks it unjust to require a crossing-sweeper in Piccadilly to tell you the road to Highgate; he has earned his copper if he had done all he professes to do and cleaned up your immediate path"; and a little later where he "shudderingly objects to the responsibility of attempting to set right a world out of joint."
Now Socialists have the audacity to maintain that it is not beyond the intelligence of the crossing-sweeper of Piccadilly to know and tell the road to Highgate, and that the time has come when no one has a right to "shudderingly object to the responsibility of attempting to set right a world out of joint."
Huxley builded better than he knew; and in spite of his detestation of Socialism it was he who built its strongest and most enduring foundation; for unanswerable as may be the economic argument in favor of Socialism, it might take centuries to prevail if there were not an equally strong scientific and ethical argument for it.
The moment that Huxley recognizes that it is by the "elimination of competition," or shall we say the "limitation of competition," by substituting human selection for natural selection, and directing selection towards an ideal that man is to progress and develop, he has recognized the scientific basis of Socialism; and when he points out that Science teaches self-restraint, human responsibility, human effort, not so much the "survival of the fittest" as fitting as many as possible to survive, he has reconciled Science and Religion.
It is probable that one of the reasons why Huxley took a pessimistic view of the future was that he despaired of finding a solution to the economic struggle. I cannot forget the melancholy with which he said one day: "I am informed that England keeps its control of the market of cotton goods by a difference in cost of production of a farthing per yard. How long can this last?" But Huxley only gave a part of the scientific argument for Socialism. For the other part we have to turn from the pages of Huxley to those of Karl Marx.
One of the most important services Karl Marx rendered humanity was the demonstration of the predominating influence of economics in the development of man, in the determining of our custom, character, and conduct.
The economic conception of history is described by F. Engels as follows:
"The materialist conception of history starts from the principle that production, and next to production the exchange of its products, is the basis of every social system; that in every society arising in history the allotment of products, and with it the division of society into classes or ranks, depends upon what is produced, how it is produced, and how when produced it is exchanged. Accordingly the ultimate causes of all social changes and political revolutions are not to be looked for in the heads of men, in their growing insight into eternal truth and justice, but in changes of the methods of production and exchange; they are to be looked for not in the philosophy, but in the economy of the epoch in question."[220]
Before elaborating this conception of history, it may be well to point out one or two elements of confusion in the terms in which it is stated. It is described as the "materialist conception of history," and for this reason many people imagine that the admission of this theory means the exclusion of the ideal. This is a profound error due to a misunderstanding of the use of the word "materialist." This word does not necessarily imply that the only proper conception of history is a materialistic one in the sense that it excludes the operation of ideals; but only that material conditions have played a predominating rôle in determining ideas.
