The aim of this article is to show how context, in its multiple forms, as well as having influence in localization, organization, government, and business of firms, is also fundamental on an epistemological level because it acts directly on the dynamics of scientific knowledge construction. It will be shown how context takes on the role of a constraint that strongly influences the growth of the endless possibilities from which a scientific knowledge emerges, and how epistemology has to rethink the definition (...) of science, taking into account that it evolves in relation with its multiple contexts with which it reinvents itself every day.
