Rola racjonalności w kształtowaniu poetyckiego obrazu świata (na przykładzie modelownia znaczenia paproci w tekstach młodej polski)

This article is an attempt at showing how various rationalities, fabulous and creative, influence the organization of the content in a work of poetry, how they intermingle and shape an informative value of a word and how, on a higher level, they decide about the form of a cognitive model. Moreover, the article shows how a change in the perspective of the vision of reality in a poetic work enriches senses whereas the coexistence of the two types of rationality and semantic tensions resulting from this coincidence generates new meanings determined by a special context that a word is used in. The impact of various types of rationality on shaping the meaning of a word in the text has been discussed following the example of the semantics of fern in Young Poland’s poetry.
