These improvements again, as well as the great inventions themselves, are usually come at in recent times in a different way from that of the old inventor. Formerly the inventor had almost nothing, before him—every department of industry had to be built up from the foundation. Now a man must build upon extensive knowledge of what has been accomplished, and must have great means at his command. What Mr. Mill has just been explaining in his new book in regard to original authorship in the present day is equally true of invention: “Nearly all the thoughts which can be reached by mere strength of original faculties have long since been arrived at; and originality, in any high sense of the word, is now scarcely ever attained but by minds which have undergone elaborate discipline, and are deeply versed in the results of previous thinking. It is Mr. Maurice, I think, who has remarked, on the present age, that its most original thinkers are those who have known most thoroughly what had been thought by their predecessors; and this will henceforth be the case. Every fresh stone in the edifice has now to be placed on the top of so many others, that a long process of climbing, and of carrying up materials, has to be gone through by whoever aspires to take a share in the present stage of the work.” That is—when we speak of invention—the inventor must be a man who is closely associated with capitalists, or be a capitalist himself. In no other way can he have the means of knowing the thousand improvements of machinery and processes which have culminated in the present factories and machines; and in no other way can he find means for experiments on the necessary scale. “Poor men,” says Sir William Armstrong, “very often come to me imagining that they have made some great discovery. It is generally all moonshine, or if it looks feasible, it is impossible to pronounce upon its value until it has passed through that stage of preliminary investigation which involves all the labour, and all the difficulty, and all the trouble.” How is a poor man to get this preliminary investigation undertaken, when the subject is an amendment of a complicated manufacturing process? The complaint, in fact, was made before the Select Committee on Technical Instruction, that English manufacturing was suffering from foreign competition, because there is less room now than formerly for the play of “untaught invention.” The machine is too perfect for the workman to meddle with; and thus the foreigner, supposed to be more technically instructed, has room to excel us—our peculiar power having been “untaught invention.”
