Epistemologiczne aspekty pragmatyki językowej: prawda w komunikacji potocznej

The article presents an issue of colloquial communication for epistemological speech acts. The article is based on the assumptions of linguistics and philosophy of language. With the support of the examples from everyday communication the article presents the relations between truth and false in speech acts. The expressions were analyzed taking into account such factors as speaker’s personality, subjectivity, context, intention of the speaker, Austin’s typology of speech acts and phatic function. It has been found that the colloquial communication is not verifiable in terms of logics, because it is dependent on non-linguistic elements which influence the notion of truth in communication.
