Concepts describe the living creatures’ essences and their evolution laws. That is what we call their ontogenetic intelligence. Living creatures possess intrinsic concepts. This means that these concepts exist in themselves and only need to be discovered. On the other hand, inanimate beings have extrinsic concepts, which are deposited on them according to their functionality. Concepts determine the ontological behavior of living creatures. As there is a generic concept for each species that defines its purpose, its expansion action (entropy) and its conservation function, such concept is cross-cultural and timeless, as long as the species does not become extinct.Functionality/Credibility Zone:-Intrinsic concepts are functional. They do not exist because someone believes them or not. On the other hand, extrinsic concepts describe the ontology of a living being and depend, for their existence, on the fact that they are believed. -While intrinsic concepts are defined by their functionality zone, extrinsic concepts are defined by their credibility zone. In both cases, concepts are not integrated by three different elements, they are “one”. The Field of Possibilities:Concepts define the field of possibilities of occurrence of events. 1) Intrinsic concepts define the possibilities of the nature of the entity. The behavior of a living being becomes influenceable if the knowledge of its concepts has been acquired.2) Extrinsic concepts define the possibilities of inanimate entities. The building and use of inanimate entities becomes possible if the knowledge of their concept has been acquired.3) Extrinsic concepts also define the possibilities of objects that are being built. Objects, as adaptive systems that need to produce results, are based on concepts that drive their functionality.
