While the Gutenberg press was perhaps one of the greatest inventions of all time, we should not let its importance blind us to other very important events in the history of linguistic development. Granted, the efficiency of printing allowed for the dissemination of much learning in Europe. Still, such printing was not unique to Europe, and even in the scope of world history, there are several events that are equally as miraculous regarding the transmission of knowledge.

For instance, most people overlook the amazing nature of the first time that human beings communicated with spoken language. Perhaps there were simple signs by which these early humans could indicate their needs to each other; however, when the first event of person-to-person speech occurred, it was far more marvelous than simple practical communication. Such speech was like a sharing in ideas. When true speech happened, persons were able to communicate knowledge to each other, freeing it from its isolation in one lonely person. By means of such speech, knowledge could be orally transmitted from generation to generation, thus preserving wisdom in a way that is completely impossible without speech.

Of course, such spoken tradition is very fragile, relying on memories and stories that are passed down from generation to generation. For this reason, the invention of writing is extremely important. In contrast to the spoken word, the written word can continue to exist and be useful so long as it can be read intelligently. Likewise, much more can be recorded than ever could be remembered by someone with the best of memories. Indeed, once these records are written, copies can be sent to anyone who is able to read the language in question. Just so, it can be translated into written copies to be read by others. For these (as well as many other reasons) the invention of writing was a very significant event in history, greatly expanding the possibilities for the exchange of knowledge.

Thus, the printing press is quite important, but it is part of a larger story. Like both spoken and written communication, it allows human beings to communicate knowledge not only to each other but also across multiple generations. Often, we think of the press merely in its ability to provide a great number of books in a short period of time; however, when considered as a chapter in this longer tale, it likewise appears as the means by which humanity is able to conquer time by allowing the knowledge of today to live for multiple generations.

What is the main idea of the third paragraph?

Adapted from The Wealth of Nations by Adam Smith (1776)

The greatest improvements in the productive powers of labor, and the greater part of the skill, dexterity, and judgment with which it is anywhere directed or applied, seem to have been the effects of the division of labor. The effects of the division of labor, in the general business of society, will be more easily understood by considering in what manner it operates in some particular manufactures. It is commonly supposed to be carried furthest in some very trifling ones; not perhaps that it really is carried further in them than in others of more importance, but in those trifling manufactures that are destined to supply the small wants of but a small number of people, the whole number of workmen must necessarily be small; and those employed in every different branch of the work can often be collected into the same workhouse, and placed at once under the view of the spectator.

In those great manufactures, on the contrary, which are destined to supply the great wants of the great body of the people, every different branch of the work employs so great a number of workmen that it is impossible to collect them all into the same workhouse. We can seldom see more, at one time, than those employed in one single branch. Though in such manufactures, therefore, the work may really be divided into a much greater number of parts, than in those of a more trifling nature, the division is not near so obvious, and has accordingly been much less observed.

To take an example, therefore, from a very trifling manufacture, but one in which the division of labor has been very often taken notice of: the trade of a pin-maker. A workman not educated to this business (which the division of labor has rendered a distinct trade), nor acquainted with the use of the machinery employed in it (to the invention of which the same division of labor has probably given occasion), could scarce, perhaps, with his utmost industry, make one pin in a day, and certainly could not make twenty. But in the way in which this business is now carried on, not only the whole work is a peculiar trade, but it is divided into a number of branches, of which the greater part are likewise peculiar trades. One man draws out the wire; another straights it; a third cuts it; a fourth points it; a fifth grinds it at the top for receiving the head; to make the head requires two or three distinct operations; to put it on is a peculiar business; to whiten the pins is another; it is even a trade by itself to put them into the paper; and the important business of making a pin is, in this manner, divided into about eighteen distinct operations, which, in some manufactories, are all performed by distinct hands, though in others the same man will sometimes perform two or three of them.

In every other art and manufacture, the effects of the division of labour are similar to what they are in this very trifling one; though, in many of them, the labour can neither be so much subdivided, nor reduced to so great a simplicity of operation. The division of labour, however, so far as it can be introduced, occasions, in every art, a proportionable increase of the productive powers of labour. The separation of different trades and employments from one another, seems to have taken place, in consequence of this advantage.
