The unicist double dialectical logic is the integrator of all logical reasoning patterns. It is homologous with the “category theory”, which is the mathematics that integrates the different mathematics by using a superior level of abstraction.

This logic, which is based on human ontointelligence, allows dealing with the dynamics, evolution and nature of adaptive systems and environments. Non-adaptive environments are considered a “particular case” of adaptive systems.

Logic can be defined as the formalization of a fallacy-free reasoning process to solve specific categories of problems. There are as many logical reasoning patterns as there are different categories of problems that have been solved using a conscious reasoning process.

Ontointelligence is the human intelligence that allows discovering the concepts and fundamentals of things. It is integrated by an ethical intelligence, a strategic intelligence and the logical type of thought that allow managing a high level of abstraction and simultaneously a high level of concretion.

There are multiple logical patterns available to solve their homologous problems.

They can be classified based on the following categories: Propositional-logic approaches, Dualistic-logic approaches, Set-logic approaches, Fuzzy-logic approaches, Predicate-logic approaches and Integrative-logic approaches. The unicist double dialectical logic approach integrates them to deal with the dynamics, evolution and nature of adaptive systems and environments.

The unicist double dialectical logic was created by Peter Belohlavek in 1986. Its application allowed its author to develop the structure of complexity sciences to study and deal with adaptive systems and environments.

It drove to the development of the unicist theory and to the discovery of the ontogenesis of evolution and established the basics to develop the unicist artificial intelligence. This logic provided the structure to develop the applied researches on social, individual and business evolution developed at The Unicist Research Institute.

Paradoxically, this unicist double dialectical logic requires both a superior level of abstraction to apprehend its structure and a superior level of operational thinking to apprehend the operation.

The use of the conclusions of this logical approach requires no abstractions, because they are self-evident. It only requires having experience in a specific action field.
