A dictionary of Marshall McLuhan’s quotations

More and more we turn from the content of messages to study total effect. Kenneth Boulding put this matter in The Image by saying, "The meaning of a message is the change which it produces in the image." Concern with effect rather than meaning is a basic change of our electric time, for effect involves the total situation, and not a single level of information movement. Strangely, there is recognition of this matter of effect rather than information in the British idea of libel : "The greater the truth , the greater the libel.”
