Not more than three decades a number of authors have begun to use the word complexity within their texts, placing it as a worthy of a jargon both academic and colloquial term. From one moment to another complexity, well or poorly understood, began circulating through the various streets of everyday life and by the different cloisters in schools and universities. Complexity is a relevant thought that must be analyzed because it brings with it new ways to understand and transform the world 4. Seen, so light and little serious, complex as that which encloses darkness, disorder, complication, aporia, tangle and there has been a reflection of the reality of complexity. For this reason, before you define, way more accurate, what is meant by complexity, it is appropriate to make some clarifications on the concept in question. According to Atlan 5 the complication refers to the specified tasks, some well-known object, they need long time to perform them or describe them in full. From the second and third rule of the Cartesian method 6 can say that tricky thing has your solution in simplifying by parties of what is difficult in yours. How complicated is divided into as many parts as possible to, in this way, studying the parties and be able to overcome the difficulty of complication.
The same does not apply to the complexity, because if this could simplify already it would not be complex but only complicated and, in any cases, resulting in the reduction of complexity 7 is not simplification but greater complexity. The word complexity etymologically comes from complexus (Latin: plecto, Plexus, com-plector, plexus: woven, braided, bound) 8 which means, according to Morin, which is woven together, this being a constituent tissue heterogeneous inseparably associated.
