rasselas.redux, Let me explain why poetry and science use diametrically opposed types of language. Science is basically common sense applied with an extreme level of rigor. The langage of science is rigorous. Its logic ought to be flawless: as per the law of identity, once the meaning of a term is given, the term retains its meaning beyond subjective, relative, arbitrary considerations. Science works with “statements”, not “sentences”, and the meaning of statements depends on “enunciation” – that is, the “context” in which a statement is formulated. The context must be declared in a way that leaves no room for uncertainty and randomness. No stone must be left unturned at every single step of the scientific inquiry. The fact that science uses analogies, models and fancy wordings, is no contra-indication to the implied rigor of its method. Poetry leaves full room for interpretation and creativity. Meaning imparted to words is expected to vary with the subjective context. The poet uses figures of speech to play dough with the linguistic material. The art of poetry works with “sentences”, whose meaning depends on grammar. In poems, grammatical rules can be loosen up at will, notably by syntactic tweaking and inversion. The litterary sense usually serves as a background to evoke a more subtle, profound message, picture, feeling, understanding. The fact that poetry can aptly convey reliable truths about the world, is no contra-indication to the implied laxness of its ways and means. To help cut on prospective confusion, it’s not a case of all-or-nothing between the two. There are such notions as interdependency, structuralism, dialectical reasoning, etc. Order, homogeneity, stability, determinism, are conditions for novelty, creativity, originality, freedom. “Necessity is the mother of invention”, the proverb says. Determinism, emergence, contingence, are natural principles of this mysterious, albeit lawful, Universe. Scientific knowledge is arrived at with its share of imagination, adventure, trial and error, boldness, madness. Think of mad geniuses who revolutionized our understanding of the world, or successful artists who exhibit self-destructive patterns, only to trap their own gifted and prolific minds into a phenomenological dead end.
