How do new tools and inventions affect societies? This question, which has become very topical in the face of a worldwide information age, was the perennial concern of Marshall McLuhan's career. Typically, he wanted to know the ramifications of new technologies. The consequences, the altering of our environment, and consequently of our self-image in the society. His purpose was to understand media's sociological, cultural and psychological impact. He developed the Tetrad, which explores collateral effects of any technology. The Tetrad asks four questions about any human invention, or artefact, whether it be physical object or system of thought. What does the invention extend or amplify? What is its initial purpose? What invention or environment will it do away with or obsolesce? What older technology will be retrieved from the past? What will the invention become when pushed to its limits? The Marshall McLuhan Media Workbook is a source of daily exercises in thinking like McLuhan.
