This paper offers an analysis of a conversation between Zagłoba and Roch Kowalski, two characters from Henryk Sienkiewicz’s The Deluge. The analysis was inspired by the occurrence of (deontic) terms within this dialogue. The question arises of whether both interlocutors are appealing to some principles of deontic logic. To answer this question, a fragment of deontic logic is reconstructed. It is shown that some parts of the conversation in question can be analyzed with help of formal-deontic devices.
