 As scholars and teachers , Innis and McLuhan shared a similar dilemma since both argued that book culture tended to produce fixed points of view and <unk> of thought ; yet both produced many books . In his introduction to the 1964 reprint of The <unk> of Communication , McLuhan <unk> at Innis 's technique of juxtaposing " his insights in a mosaic structure of seemingly unrelated and <unk> sentences and aphorisms " . McLuhan argued that although this made reading Innis 's dense prose difficult — " a pattern of insights that are not packaged for the consumer palate " — Innis 's method <unk> " the natural form of conversation or dialogue rather than of written discourse " . Best of all , it yielded " insight " and " pattern recognition " rather than the " classified knowledge " so <unk> by print @-@ trained scholars . " How exciting it was to encounter a writer whose every phrase invited prolonged meditation and exploration " , McLuhan added . McLuhan 's own books with their reliance on aphorisms , puns , <unk> , " probes " and oddly juxtaposed observations also employ this mosaic technique .
