Essential McLuhan 136 spaces had unique properties and impinges upon our other senses or spaces in unique ways. Today, then, it is easy to understand the invention of the alphabet because, as A.N.Whitehead pointed out in Science and the Modern World (p. 141) the great discovery of the nineteenth century was the discovery of the method of discovery: The greatest invention of the nineteenth century was the invention of the method of invention. A new method entered into life. In order to understand our epoch, we can neglect all the details of change, such as railways, telegraphs, radios, spinning machines, synthetic dyes. We must concentrate on the method in itself; that is the real novelty which has broken up the foundations of the old civilization …. One element in the new method is just the discovery of how to set about bridging the gap between the scientific ideas, and the ultimate product. It is a process of disciplined attack upon one difficulty after another. The method of invention, as Edgar Poe demonstrated in his “Philosophy of Composition,” is simply to begin with the solution of the problem or with the effect intended. Then one backtracks, step by step, to the point from which one must begin in order to reach the solution or effect. Such is the method of the detective story, of the symbolist poem, and of modern science. It is, however, the twentieth century step beyond this method of invention which is needed for understanding the origin and the action of such forms as the wheel or the alphabet. And that step is not the backtracking from product to starting point, but the following of process in isolation from product. To follow the contours of process as in psychoanalysis provides the only means of avoiding the product of process, namely neurosis or psychosis. It is the purpose of the present book to study primarily the print phase of alphabetic culture. The print phase, however, has encountered today the new organic and biological modes of the electronic world. That is, it is now interpenetrated at its extreme development of mechanism by the electro-biological, as de Chardin has explained. And it is this reversal of character which makes our age “connatural,” as it were, with non-literate cultures. We have no more difficulty in understanding the native or non- literate experience, simply because we have recreated it electronically within our own culture. (Yet post-literacy is a quite different mode of interdependence from pre-literacy.) So my dwelling upon the earlier phases of alphabetic technology is not irrelevant to an understanding of the Gutenberg era. Colin Cherry had this to say about early writing:
