What of these other fours?
 Post appears BELOW Table of Contents.
 This blog focuses on similarities between others' four-folds, tetrads, tetrachotomies, and mine, and includes links to online information on others’ fours in their own terms. It results from overgrowth of an old post at The Tetrast "What of these other fours?".

Claude Shannon's communication-theoretic scenario, when cast as four stages, involves source, encoding (sender), decoding (receiver), and destination . (However, the communication channel is often included as a stage, on a par with the others and between encoding and decoding. Solutions to the challenge of the channel and its noise shape a lot of communication theory; but the challenge is to minimize the noise and avoid information loss; the generation or modification of signals is desirable only in the other stages.) My augmentation of C.S. Peirce's semiotic process (a.k.a. semiosis) to include a fourth and (dis)verificatory/(dis)confirmatory stage brings semiosis into alignment and correlation with the fourfold version of Shannon's scenario. The field of experience in or against which a decoding (and ultimately the encoding and source as well) is tested is, first of all, that of the destination. Note: semiosis differs in that it is not code-bound like info-theoretic communication; the continual renovation and occasional redesign of a communication system is a kind of "evolution" (pace biologists!) whereby semiosis is arguably definable, and which, I argue, comes about through such testing. As for channels and noise, I'm unsure of precisely what the semiotic analogs to them would be. - posted by The Tetrast @ 10:26 PM [top of post] [top of page] Copyright © BenjaminðA.ðUde11.
