Abstrakt:
The purpose of this article is to answer the question, whether there is the possibility of self-delusion in mental content, which is understood as a set of conscious content constituting self-knowledge – if such illusions are possible, this knowledge could be challenged. More precisely, could a subject be wrong about his own propositional attitudes? Assuming a positive answer to this question, first, proper examples of such confusion should be found and, second, the Cartesian paradigm of self-knowledge should be revisited.
