The principal strength of the telegraph was its capacity to move information, not collect it, explain it or analyze it. In this respect, telegraphy was the exact opposite of typography. Books, for example, are an excellent container for the accumulation, quiet scrutiny and organized analysis of information and ideas. It takes time to write a book, and to read one; time to discuss its contents and to make judgments about their merit, including the form of their presentation. A book is an attempt to make thought permanent and to contribute to the great conversation conducted by authors of the past. Therefore, civilized people everywhere consider the burning of a book a vile form of anti-intellectualism. But the telegraph demands that we burn its contents. The value of telegraphy is undermined by applying the tests of permanence, continuity or coherence. The telegraph is suited only to the flashing of messages, each to be quickly replaced by a more up-to-date message. Facts push other facts into and then out of consciousness at speeds that neither permit nor require evaluation.
