The theoretical problem of complexity consists of entering the black box and consider the logical and organizational complexity. Not just renewing the conception of the object but there is need to revert the epistemological perspectives of the subject, in this case the scientific observer. Since scientific per se was to eliminate the imprecision, ambiguity and contradiction and must accept a certain vagueness as it is happening in mathematics in dealing with datasets imprecise. This complex thought should bring the principles from which emerged the new paradigm of complexity. Morin (1998) proposes these principles to help us think complexity: the Dialogic: two logics as stability / instability and order / disorder, that are necessary from one to the other.
The organizational recursion: everything that is produced rejoins about what occured (example individuals to be produced are producing process that will continue). This recursive idea breaks the linear idea of cause/effect. The Hologramatico principle: not only the part is in all but the everything is in part (E.g., in the biological world, every cell in our body contains all of the genetic information of the Agency). In nature there are trends of increasing complexity, allowing us to determine models of low complexity, medium complexity and high complexity depending on developments of the self-organization (autonomy, individuality, wealth of relationship with the environment environment, aptitude for learning, inventive, creativity) and to the human brain as a phenomenon of very high complexity. Finally, transcribe a phrase from the book the chance and necessity. Essay on the natural philosophy of modern biology of Jacques Monod that reflects the complex approach to the vital phenomenon: A universal theory which contains relativity, quantum theory and the theory of elementary particles and that contemplate the evolution of the universe from conditions start them, could not contain the biosphere as a deductible phenomenon of first principles. The biosphere constitutes a class of objects or phenomena compatible with first principles, but not deductibles of these principles, therefore, essentially unpredictable.
