This paper aims to show how the emerging paradigm, -a new theory of rationality proposed by Beynam and returned by Miguel Martinez- provides important elements in the epistemic foundation of Information Science, including an Information and Documentation System-SID. To this end first will be a conceptual approximation of what is meant by taking the proposed SID Miguel Angel Rendon, then examine the extent of the most important paradigms adopted by the discipline to follow the design of emerging paradigm, to show how this new proposal is based on the tendency to order in open systems, in a systemic ontology and a complementarity of approaches, provides greater understanding of the epistemic aspects of Information Science.
