"Without books the development of civilization would have been impossible. They are the engines of change, windows on the world, "Lighthouses" as the poet said "erected in the sea of time." They are companions, teachers, magicians, bankers of the treasures of the mind, Books are humanity in print."

Print, in even more revolutionary ways than writing, changed the very form of civilization. ...the Protestant Revolution was contemporaneous with the invention of moving type. ...the printing and distribution of millions of Bibles made possible a more personal religion, as the Word of God rested on each man's kitchen table. The book, by isolating the reader and his responses, tended to separate him from the powerful oral influences of his family, teacher, and priest. Print thus created a new conception of self as well as of self-interest. At the same time, the printing press provided the wide circulation necessary to create national literatures and intense pride in one's native language. Print thus promoted individualism on one hand and nationalism on the other.

The discovery of the art of Printing unbarred afresh the gates of Heaven, and let in that flood of light, of knowledge, and of wisdom, which enabled men to emancipate themselves again from the slavery of superstition—to take their proper place in the ranks of created beings—and in ennobling themselves, in gradually exalting their understandings and amending their hearts, to pay at length the worthiest homage to the goodness of their common Parent, and prove themselves to be—as the Almighty himself originally formed them—inferior only to the Angels.

Language gradually varies, and with it fade away the writings of authors who have flourished their allotted time; otherwise, the creative powers of genius would overstock the world, and the mind would be completely bewildered in the endless mazes of literature. Formerly there were some restraints on this excessive multiplication. Works had to be transcribed by hand, which was a slow and laborious operation; they were written either on parchment, which was expensive, so that one work was often erased to make way for another; or on papyrus, which was fragile and extremely perishable. Authorship was a limited and unprofitable craft, pursued chiefly by monks in the leisure and solitude of their cloisters. The accumulation of manuscripts was slow and costly, and confined almost entirely to monasteries. To these circumstances it may, in some measure, be owing that we have not been inundated by the intellect of antiquity; that the fountains of thought have not been broken up, and modern genius drowned in the deluge. But the inventions of paper and the press have put an end to all these restraints. They have made everyone a writer, and enabled every mind to pour itself into print, and diffuse itself over the whole intellectual world. The consequences are alarming. The stream of literature has swollen into a torrent — augmented into a river — expanded into a sea.

Every school boy and school girl who has arrived at the age of reflection ought to know something about the history of the art of printing, papermaking, and so forth. … All children will work better if pleased with their tools; and there are no tools more ingeniously wrought, or more potent than those which belong to the art of the printer. Dynasties and governments used to be attacked and defended by arms; now the attack and the defence are mainly carried on by types. To sustain any scheme of state policy, to uphold one administration or to demolish another, types, not soldiers, are brought into line. Hostile parties, and sometimes hostile nations, instead of fitting out martial or naval expeditions, establish printing presses, and discharge pamphlets or octavoes at each other, instead of cannon balls. The poniard and the stiletto were once the resource of a murderous spirit; now the vengeance, which formerly would assassinate in the dark, libels character, in the light of day, through the medium of the press. But through this instrumentality good can be wrought as well as evil. Knowledge can be acquired, diffused, perpetuated. An invisible, inaudible, intangible thought in the silent chambers of the mind, breaks away from its confinement, becomes imbodied in a sign, is multiplied by myriads, traverses the earth, and goes resounding down to the latest posterity.

The invention of printing did away with anonymity, fostering ideas of literary fame and the habit of considering intellectual effort as private property. (p. 122)

In the early days of America’s democracy, education and literacy were the prerequisites for establishing a connection to the body politic. In a world where communication was dominated by the printed word, those who learned to read also learned to write. Gaining the ability to receive ideas was automatically accompanied by the ability to send ideas, expressing your own thoughts in the same medium through which you took in the thoughts of others. The connection, once established, was two-way. As Thomas Jefferson wrote, “The art of printing secures us against the retrogradation of reason and information.” In practice, the use of the printing press was mainly by the elites in America’s early decades, and the scurrilous, vitriolic attacks of that age certainly rivaled the worst of any modern political attacks. Nevertheless, the easy accessibility to the printed word opened up avenues of participation in the dialogue of democracy for people like Thomas Paine, who had neither family wealth nor political influence — other than what he gained with the eloquence of his writing. The age of printed pamphlets and political essays has long since been replaced by television — a distracting and absorbing medium that seems determined to entertain and sell more than it informs and educates. If the information and opinions made available in the marketplace of ideas come only from those with enough money to pay a steep price of admission, then all of those citizens whose opinions cannot be expressed in a meaningful way are in danger of learning that they are powerless as citizens and have no influence over the course of events in our democracy — and that their only appropriate posture is detachment, frustration, or anger.

What gunpowder did for war, the printing press has done for the mind.

From the time when the exercise of the intellect became a source of strength and of wealth, we see that every addition to science, every fresh truth, and every new idea became a germ of power placed within the reach of the people. Poetry, eloquence, and memory, the graces of the mind, the fire of imagination, depth of thought, and all the gifts which Heaven scatters at a venture turned to the advantage of democracy; and even when they were in the possession of its adversaries, they still served its cause by throwing into bold relief the natural greatness of man. Its conquests spread, therefore, with those of civilization and knowledge; and literature became an arsenal open to all, where the poor and the weak daily resorted for arms.

It was early in the Seventeenth Century that Francis Bacon remarked on three recent inventions already transforming the world: the compass, gunpowder and the printing press. Now the links between the nations first forged by the compass have made us all citizens of the world, the hopes and threats of one becoming the hopes and threats of us all. In that one world's efforts to live together, the evolution of gunpowder to its ultimate limit has warned mankind of the terrible consequences of failure. And so it is to the printing press — to the recorder of man's deeds, the keeper of his conscience, the courier of his news — that we look for strength and assistance, confident that with your help man will be what he was born to be: free and independent.

What gunpowder did for war, the printing press has done for the mind, and the statesman is no longer clad in the steel of special education, but every reading man is his judge.

Has not printing freed the education of the people from all political and religious shackles? It would be vain for any despotism to invade all the schools ... The instruction that every man is free to receive from books in silence and solitude can never be completely corrupted. It is enough for there to exist one corner of free earth from which the press can scatter its leaves. How with the multitude of different books, with the innumerable copies of each book, of reprints that can be made available at a moment’s notice, how could it be possible to bolt every door, to seal every crevice through which truth aspires to enter?

The discovery of printing in the middle of the fifteenth century implied the beginning of a return to a type of civilization dominated by the eye rather than the ear.
