This study on the reality of images is based on various ideas of realism. new Realism asserts the reality of objects independent of human ideas. Kant’s realism is based on the way that the subject includes the object, and the realm of cognition is limited to phenomena, while the pure object, the thing-in-itself, is excluded from the phenomena. However, the “thing-in-itself,” which was already given as an “object of sense” as Kant’s premise, became the object of phenomenological or ontological realism by Husserl and Heidegger. In established Modern Realism, Whitehead’s Realism becomes the cornerstone for developing “realistic dialectics.” However, in Whitehead’s Realism, eternal objects remain a Platonic metaphysical mechanism. After that, among recent Realisms, Meillassoux’s Speculative Realism claims “ancestrality” and “non-thinking” as solutions to resolve the contradictions in Correlationism and sever the relationship, and Harman’s Object-Oriented Ontology with Speculative Realism is a modern and concrete theory in New Realism. However, the new subject form is omitted in New Realism. Therefore, in this study, I propose “realistic dialectics” that synthesizes the research on the reality of images and the new subject form (“body-subject”) and previous studies on dialectics from the perspective of New Realism.
