Haiku assumptions
From the abstract of the essay “Blending and an Interpretation of Haiku: A Cognitive Approach” by Masako Hiraga, published in Poetics Today 20.3, Fall 1999:
[H]aiku texts… assume common knowledge that shapes the cultural cognitive model [such as] (1) pragmatic knowledge of the context, such as time, place, customs, life, and so on; (2) folk models, which originate from myth and folk beliefs about the conceptualization of existing things; (3) conventional metaphors, in George Lakoff and Mark Johnson’s sense, which have been conventionalized in a given speech community over time, and which a poet exploits in nonconventional ways; and (4) the iconicity of kanji, Chinese ideograms, which link form and meaning, particularly with regard to their etymological derivation, and thereby serve as a cognitive medium for haiku texts.
