Setting extensive manuscripts by hand is, of course, a very slow and laborious process, and as the printing industry grew in extent and importance it was only natural that efforts should be made to devise a means of setting type mechanically at greater speed and less cost.... The failures were myriad. All efforts to take the foundry type used by the compositor and set it up mechanically came to naught. Finally, however, Ottmar Mergenthaler invented a machine which, by the action of a keyboard somewhat resembling that of a type-writer, assembled not type but matrices and, when a whole line was set and spaced, cast this line in one piece, or "slug," of type metal. This machine, which was first put into practical use in 1886, and appropriately christened a "linotype," gave a revolutionary impetus to the printing industry ... as with all new inventions of importance it was expected that thousands of compositors would be thrown out of work. But, again as usual, the industry grew so fast that more men were employed than before.
This device is not the only machine which sets type. On its heels came the monotype which employs the pianola principle for power transmission and is for some purposes preferable. The technical advantages of one or the other are irrelevant to our theme. What makes printing by linotype an outstanding achievement of nineteenth-century technology is that it permits type-setting to keep pace with the tempo of topical affairs at a time when a railroad schedule co-ordinated by telegraphy has made man minute-conscious for the first time in history. It is at once a new goad to the new social discipline of punctuality and a new means of satisfying an appetite for sensation among a section of the population not as yet attuned to habitual reading....
That the Moslem world of Omar Khayyam and Alkarismi transmitted so many of the benefits of Chinese civilisation to the West, reaping themselves no advantage from the invention of printing, illustrates a truth which Marxist dogma ignores. Fruitful innovation is, as the Marxist rightly asserts, the result of interplay between human needs and natural resources; but the triple formula of means, motive and opportunity suffices to account for the vagaries of man's history only if we recognise the inherent inertia of human motivation. Beliefs do not come from heaven; but they have a remarkable tenacity in the teeth of worldly profit, a tenacity forcefully illustrated by two facets of the Moslem creed. In the racy, though none the less scholarly, account of the history of printing already cited several times in this chapter, McMurtrie states:
