Introduction

General logic, structuring, will be denoted by function L. Its varieties will then be called specialized logical functions. If one considers that not a single sociotype is same as the other in its logical thinking, from this follows that there must be as many specialized functions as there are sociotypes - sixteen. Specialized functions I will denote with + and - signs as well as make use of operations from propositional logic. In this article when the word "logic" carries the meaning of structural logic rather than business logic.

1. Sign dichotomies

Originally I have assigned the positive and negative signs of communicative functions, including logic, to the dichotomy "left/right" [also known as process/result]. "Right" logic I have denoted with symbol +L and left logic by -L. What is the difference between these two logic types?

Right/Process/Evolutionary logic: straight and absolute, has no reverse feedback. This type of logic as if delineates contours of forms on some background that is then discarded as insignificant. It is characterized by absence of context and is categorical, explicit in judgements.

Left/Result/Involutionary logic: inversive, derived from straight logic using the operation of subtraction. It is reflexive and considers not the upfront side as much as the back side of the coin. It underlines the background, contextual dependencies of judgements.

Right logic (process): ILE, SEI, EIE, LSI, SEE, ILI, LSE, EII
Left logic (result): ESE, LII, SLE, IEI, LIE, ESI, IEE, SLI

However, there is another way of assign + and - signs that is no less substantiated: using the dichotomy of negativism/positivism. Then +L will denote the logic of positivists while -L will denote the logic of negativists.

Positivist logic: unified, accordant in all parts. This kind of logic comes closest to what is known as formal logic. An example of this kind of logic is syllogism - inferential sequence of arguments described by Aristotle in "Organon".

Negativist logic: logic of contradictions. Dialectic, containing in itself oppositions and contradictions. This logical instrument works best when analyzing complicated multilayered systems.

Positivists: ILE, ESE, LSI, ...
