Abduktsioonist mitmekeelses süsteemis: psühhiaatriline implikatsioon
On abduction in a polycoded system: psychiatric implication

Summary/Abstract: Differences of code between communicating systems have been addressed as a condition for the generation of new information, though not sufficient in itself to guarantee its adequacy and constructive nature, that is, its environmental ties and interior coherence. The article approaches this problem through Charles S. Peirce’s notion of “abduction” as a certain context-sensitive concept of logic, which describes the preliminary, creative and hypothetical phase in the classification of phenomena — in learning to perceive them. In addition to the continuity which, regardless of its creative nature, is maintained with prior life experience in (non-pathological forms of) abduction, inseparable bonds between the latter and the subject’s affective integrity and tone are highlighted. Correspondingly, the shortcomings in logical reasoning manifested in the affective thought disorder known as schizophrenia do not represent a distinctive form of syllogistic inference, but go back to insufficient organization at the level preceding/below symbolic language that would normally constrain the abductive process (of determining premises). Besides the concepts of abduction and polysodedness, the notion of double description as a form of bringing together information from different sources is discussed and, leaning on the works of Peirce, Gregory Bateson and Juri Lotman, the possibility of interpreting schizophrenia as a specifically abductive disorder in polycoded double description is brought out.
