Derrida explores this undecidable term. In poetry, the pharmakon captures language's dual nature: it can cure or corrupt, enlighten or deceive. A poem can be a healing spell or a destructive force. Poets are aware of this ambiguity, using language's power to affect the reader. This concept reveals that poetic meaning is never simple, containing within it the potential for both good and ill, a dangerous supplement.

Pharmakon is an ancient Greek word that carries a fundamental ambiguity, meaning simultaneously a remedy, a poison, and a scapegoat. It is a substance that can heal or harm, depending on the dose and the context. Jacques Derrida famously explored this concept, using it to deconstruct the binary opposition between good and evil, inside and outside. In poetry, the pharmakon captures the dual, undecidable power of language itself: it can cure (by giving meaning, solace, or revelation) or it can poison (by causing misunderstanding, harm, or deception). A poem itself can be seen as a pharmakon, a beautiful and dangerous gift. This term reveals that poetic meaning is never simple or univocal but contains within it the potential for both creation and destruction.
