Keywords of Systemic Vision is meant to be an encyclopedia of Systemic and Complex science. The word ¿encyclopediä refers to definitely acquired information and deep knowledge in a given domain, so that also people who do not belong to the related scientific community can rely on accurate representations of that object. However, Complexity science refers to phenomena, for which it is impossible to find objective information, for reasons such as chaotic evolution, high number of variables, observers¿ bias etc. Consequently, the expectations of an encyclopedia of Complexity science should be different from those of a traditional one: this work highlights the incertitude that has always affected complex phenomena, as well as the ways of dealing with this incertitude in very different scientific domains.
