Abstract

_Abstract_ Constructivism is a philosophical current that manifests itself greatly within the realm of contemporary epistemology. Its bases come from the idea that knowledge is not only actively constructed by the observer but also provides a lens through which reality can be interpreted as a result of experiences. This paper traces a brief interdisciplinary curve that outlines some of the most important philosophical approaches that contributed to the consolidation of this school of thought for more than twenty-five centuries. _Keywords_: Constructivism, Cybernetics, Epistemology, History of Philosophy, Perception, Reality.
