Realism is often presented as a defence of the existence of certain objects, or, in a way that must probably be distinguished, of the objectivity of certain thoughts or statements. This text discusses these presuppositions, questioning the notions of object and objectivity. It highlights the underlying perspectival metaphor that seems to be constitutive of modern philosophy, and questions its limits. After criticizing a conception of thought and discourse that understands their respective engagements with reality on the model of perception, it questions the adequacy, constantly presupposed by modern philosophy, of the perspectival model as an interpretation of perception itself. The notion of perspective and the notion of object that depends on it are not able to provide by themselves any key to reality. One must rather turn the problem upside down and become aware that there is no perspective and therefore no O object in this sense without real conditions.
