Perhaps the most precious possession of man is his abiding awareness of the Analogy of Proper Proportionality, the key to all metaphysical insight, and perhaps the very condition of consciousness itself. This analogical awareness is constituted of a perpetual play of ratios among ratios. A is to B, what C is to D, which is to say the ratio between A and B, is proportionable to the ratio between C and D, there being a ratio between these ratios, as well, this lively awareness of the most exquisite delicacy depends upon there being no connection whatsoever between the components. If A were linked to B, or C to D, mere logic would take the place of analogical perception, thus one of the penalties paid for literacy and a high visual culture is a strong tendency to encounter all things through a rigorous storyline, as it were. Paradoxically, connected spaces and situations exclude participation, whereas discontinuity affords room for involvement. Visual space is connected and creates detachment or non-involvement. It also tends to exclude the participation of the other senses.
Truth to the analogist, McLuhan said, is 'a creative act': "a ratio between the mind and things, made by the shaping imagination." Truth to the logician is mere "mechanical matching" of object with object. To the analogist the world is invention itself, what McLuhan in his later shorthand would abbreviate to 'percept'. The logician by contrast will flatten, fix, nail down every percept into what McLuhan would call 'concept'.
