Abstract
In the Western philosophical tradition, thinkers linked to classical realism have resorted to two images to illustrate the realist conception: that of the object that scientists think exists “outside them” and that of the object that “does not depend on them” because they cannot modify or change it at will. Agazzi has exposed in his work why “inside”, “outside” and “Independence” do not seem to him to be schemes usefully applicable in the discussion of realism. This article presents a brief synthesis of the intellectual career of the Italian philosopher and physicist Evandro Agazzi, explaining the influence of Gustavo Bontadini’s objectualism on his epistemological proposal; subsequently, it develops Agazzi’s response to the dispute between idealism and realism based on concepts such as resistance, referentiality, protocolarity and operationality. Finally, a conclussion is offered by way of closure.
