Abstract

Certain poets tell stories, other only appreciate the palpable aspects of signs . The latter frequently use puns, thus stressing formal analogies between words .This tends to make us accept that formal analogy results in sense analogy. The logical structure of this reasoning is explained and shown erroneous, for contrarily to science metaphors and puns in poetry are equations or models which do not operate.But these proceedings are in use and it is inadequate to claim that they are but deceits or illusions. In fact poetry is strictly imaginary, its universe is one of pure representation and it recuses any checking by reality or experience‐which is of basic importance in any scientific proceeding. In the last end, this characteristic appears as the only real difference between poets and scientists, both of whom work by application of analogic models
