Materials and Methods of Writing
Stone was the first writing surface and sharper, harder stones the first marking instruments. People gradually discovered natural dyes and inks to stain the stone cave walls and roofs they wrote on (see the cave painting of bison above from Altamira in Spain). The Egyptians incised plaster on walls with their sophisticated hieroglyphs. For everyday purposes, the Egyptians developed the first pre-cursor of paper. They glued together many layers of a reed called papyrus (which gives us the base of the word paper) to get a delicate sheet of material which would take ink. Other cultures learned to use leather or the broad leaves of plants. Eventually Europeans discovered that the treated skin of calves or sheep would yield a precious, smooth, white surface for writing called, respectively, vellum and parchment. Both vellum and parchment took about three weeks of intense hand labor to make, and both were very expensive.
In about 1400, the Italians discovered a way to break down old cloth into its individual fibers. Using a fine screen, they caught the fibers and pressed the water out. When the fiber was dry, they had a sheet of paper. Paper turned out to be quick and inexpensive to make, and the secret of paper-making spread north throughout Europe very quickly. (The Chinese had invented paper independently centuries earlier.) Suddenly it became cost-effective to write things down instead of laboriously memorizing them.
Later this same century, Johannes Gutenberg expanded on the idea of printing and made it feasible to print mass quantities of ordinary things. Before him, people hand-carved wooden figures and inked them in order to stamp them onto paper. Such plates were used mostly for pictures which were then hand-colored. The trouble with using wooden blocks for printing was that they took a long time and great skill to carve but only lasted for about a hundred impressions before the wood fibers broke down from pressure and ink. Gutenberg's contribution was making moveable type out of relatively inexpensive and long-lasting metal. Within fifty years, the intellectual face of Europe changed because of the sudden availability of books and other publications. It is not too much to say that democracy would never have developed without the printing press and cheap paper.
Disadvantages of Writing
Plato and his teacher Socrates were alive when writing first swept through Greece. Using Socrates as a character in one of his Dialogues, Plato expressed his reservations about the changes in society that he believed writing would bring. His opposition was two-fold:
He believed that writing would destroy the memory of the people. About this he was quite correct. People in his day could memorize, on only a few hearings, tens of thousands of lines of poetry word perfect. Writing destroyed that ability in only a few generations.
He believed that it was dangerous to write because the ideas of the writer could be misunderstood by the reader. If people misunderstand a speaker, the speaker is present to correct the misunderstanding. He can also control who his listeners will be. Writing has always carried the danger that the wrong person might get hold of the wrong information or form the wrong impression.
From the perspective of thirty centuries later, most of us are willing to live with these disadvantages. Because we have writing:
We notice differences over time. There was no history before people wrote things.
We do not waste much brain power merely remembering details; we can use those details in higher order reasoning.
We are not limited to our own experiences in order to gain knowledge. We don't have to rediscover knowledge in every generation, nor do we have to have personal contact with people who have specialized knowledge that we need.
We are capable of ruling ourselves in democracies now that knowledge is not entirely dependent on social class.
We can build on the knowledge of others to create new technology which revolutionizes our lifestyles in much less than a generation. The poorest among us, even those living in the most squalid conditions, have comforts better, in many respects, than the richest king of the Middle Ages.
