#contradictory

• Antinomic — Containing an antinomy or relating to an antinomy; expressing a profound and seemingly insoluble contradiction between two laws, principles, theses, or conclusions, even though each of them is considered valid, logically demonstrable, or historically and legally justified.
• Self-negated — Having been rejected, invalidated, or canceled by itself; a system, concept, statement, or individual that has undergone a process of self-negation, thereby losing its initial validity or former identity. In logic and epistemology, it describes a paradoxical state where the constitutive terms of a theoretical structure mutually cancel each other out by their very utterance.
