Popper and Quine. Realism, Objectivity and Objectivism in Scientific Theories with Respect to Relativism: a semantic question

Abstract

The correspondence theory of truth can be arranged in such a way as to contain aspects of a «molecular» holism, in which background knowledge is linked but kept distinct from the content of the single proposition. Within this vision, the proposition can still be a «representation» of the fact, always approximate and renegotiable, which however illustrates the structure of the state of affairs in order to illuminate also the molecular group of states of affairs, of finite number, connected to it. The theories describe or represent real aspects of the world but these aspects, as in the Popper’s well-known similitude, can always be deepened and they are never definitive, like the different levels of reality identified by a powerful microscope.
