To engage the written word means to follow a line of thought

From Neil Postman's Building a Bridge to the 18th Century .

From Erasmus in the sixteenth century to Elizabeth Eisenstein in the twentieth, almost every scholar who has grappled with the question of what reading does to one's habits of mind has concluded that the process encourages rationality; that the sequential, propositional character of the printed word fosters what Walter Ong calls the "analytic management of knowledge." To engage the written word means to follow a line of thought, which requires considerable powers of classifying, inference-making, and reasoning. It means to uncover lies, confusions, and overgeneralizations, to detect abuses of logic and common sense. It also means to weigh ideas, to compare and contrast assertions, to connect one generalization to another. To accomplish this, one must achieve a certain distance from the words themselves, which is, in fact, encouraged by the isolated and impersonal text. That is why a good reader does not cheer an apt sentence or pause to applaud even an inspired paragraph. Analytic thought is too busy for that, and too detached.
