Organismic Set Theory and Relational Biology

[[../NicolasRashevsky/|Nicolas Rashevsky]] defined the mathematical [[../PreciseIdea/|concept]] of [[../RSystemsCategory/|organismic sets]] for different levels of organization in living organisms by means of sets of several distinct [[../Bijective/|types]]. Thus, in the case of organismic sets of zero-th order, S0, the elements represent genes, and a concrete S0c is defined as the set of all genes [Gn] of a specific organism or organism type (`species'); alternatively, S0c can be defined as a set [[../CategoricalGroupRepresentation/|representation]] of any organismic genome, GO. The latter are then considered together with inputs ei from the environment, as well as their activities ai and [[../Bijective/|relations]] Rij among [[../TheoryOfOrganismicSets/|organismic set]] elements (genes in the case of S0), where i,j are indices in a countable, index set I. Thus, Rashevsky's organismic set ([[../OS/|OS]]) theory is part of [[../AbstractRelationalBiology/|abstract relational biology]]. At the next level of biological organization, cells are considered as first order organismic sets , S1, whereas multi-cellular organisms are represented by organismic sets of second order, S2, whose `elements' are the first order organismic sets, or cells, S1. Attempts were then made by Rashevsky to expand his [[../TheoryOfOrganismicSets/|theory of organismic sets]] to organizational models of human societies. Results from such studies of relations between sets were considered to be far more important than the numerical or quantitative aspects that play such important roles in physics and chemistry. A number of interesting results were obtained by means of standard (Boolean) logic [[../Predicate/|predicates]] applied to organismic sets and their relations. Further details can be found in the publications listed below and the references cited therein. Subsequently, autopoietic theories have enlarged upon, and also extended, the application of organismic sets to biological [[../SimilarityAndAnalogousSystemsDynamicAdjointnessAndTopologicalEquivalence/|systems]] and Ecology.
