"SIGNIFICS" - OR MENTAL HYGIENE (p.219) - Colin Cherry

"Information" in most, if not all, of its connotations seems to rest upon the notion of selective power. The Shannon theory regards the information source, in emitting the signals (signs), as exerting a selective power upon the ensemble of messages. In the Carnap-Bar-Hillel semantic theory, the information content of statements relates to the selective power they exert upon ensembles of states. Again, at its pragmatic level, in true communicative situations [...] a source of information has a certain value to a recipient, where "value" may be regarded as a "selective power." Gabor, for example, observes that what people value in a source of information (i.e., what they are prepared to pay for) depends upon its exclusiveness and prediction power; he cites instances of a newspaper editor hoping for a "scoop" and a racegoer receiving information from a tipster. "Exclusiveness" here implies the selecting of that one particular recipient out of the population, while the "prediction" value of information rests upon the power it gives to the recipient to select his future action, out of the whole range of prior uncertainty as to what action to take. Again, signs have the power to select responses in people, such responses depending upon a totality of conditions. Human communication channels consist of individuals in conversation, or in various forms of social intercourse. Each individual and each conversation is unique; different people react to signs in different ways, depending each upon their own past experiences and upon the environment at the time. It is such variations, such differences, which gives rise to the principal problems in the study of human communication. (p. 244-5)

[...] we can strip off all grammatical clues to sentence structure, all affixes and prepositions, and yet still achieve communication. Thus restricted to nouns, simple "stories" can be told in word chains: <I ID=Woman_street_crowd> Woman, street, crowd, traffic, noise, haste, thief, bag, loss, scream, police.... Again, the reader's past experience of his language is sufficient to restore the missing elements, sufficiently accurately for the purpose. But of course, not only does the reader have experience of sentence structure, enabling him to supply the missing syntactical elements, but also he has experience of typical contexts in which the various words are used; many words bear an aura about with them. It might be more difficult to tell a tale about a policeman who robbed a woman, for instance, with so little redundancy! (p.122)

To take another simile [that the brain is like a machine], if we imagine a great library containing books which have a vast number of cross references one to another, then should one whole shelf be burned, it might be possible to reconstruct the lost books -- but somewhat less perfectly than at first.
