Encyclopedia > Polycontexturality

Gotthard Gunther's term for Subjectivity. His school of second-order cybernetics is the foundation of polycontextural logic. Gotthard Günther (in the USA as well: Gotthard Gunther, in Austria: Guenther), June 15, 1900 - November 29, 1984, has been a German philosopher. ... This article is in need of attention. ... Cybernetics is a theory of the communication and control of regulatory feedback. ...

It is not meant as an indroduction to Polycontexturality.
His aim was to develop a philosophical theory and a mathematics of dialectics and of self-referential systems - a cybernetic theory of subjectivity as an interplay of cognition and volition.
Polycontextural logic is a many-systems logic, a dissemination of logic, in which the classical logic systems (called contextures) are enabled to interplay with each other, resulting in a complexity which is structurally different from the sum of its components.
LIfe as Polycontexturality, Some Remarks (1060 words)
PolyContextural Logic (PCL) represents an intrinsic parallel calculus where different logical domains (contextures) are closely interwoven with each another by means of new logical operators.
Although the smallest polycontextural unit is given by three contextures (m=3), one can easily show that polycontexturality begins with four (m = 4) and not with three (the triad, m = 3) which means that a complete logical system only results with m = 4 and not with m = 3.
In other words, the smallest meaningful polycontextural logical system is given by a structure with four (logical) positions distributed/mediated over six two-valued logical domains/contextures (or four three-valued contextures, or one four-valued contexture).
