Né roccia né palude

[Autom. eng. transl.] This contribution reconstructs the passage from a "strong" conception of knowledge to the "variegated" "weak" model, which highlighted the limits of the previous approach. The "strong" model, supported in the con-temporary age by neo-positivism, has a long tradition since the modern age, as it means knowledge as episteme. From Popper onwards, epistemology has taken note that the foundationalist model is unsustainable, but has not been able to construct an alternative model that avoids both relativism and skepticism. This essay suggests a direction in which epistemology can move in order to rethink and, in some cases dissolve, the main problems raised by the crisis of the "strong" model, adopting a systemic perspective, according to which knowledge is not a mere aggregate of elements, but it is such thanks to the relationships and the interactions that are realized between subject and object and among the various knowing subjects.
