 The most significant aspect of Bacon’s grammatical analysis is one that will be replicated in his later work on semiotics. This is his intentionalist analysis. The reasons connected to grammatical analysis cannot be discovered or applied mechanically: they are dependent on the signifying intention of the speaker (intentio proferentis). This kind of analysis is found in Robert Kilwardby and in many similar texts on sophisms. As Rosier-Catach puts it, “The correctness of a statement does not depend solely on its conformity with the rules of grammar but equally on its adequateness with its signifying intention. Sometimes indeed, because the speaker wishes to signify some precise idea, he may legitimately distance himself from the normal rules” (Rosier-Catach 1997, 73). Still, this freedom is not absolute; it must be justified linguistically. Even elliptical expressions such as ita missa est have within them the capacity to allow further application of formulas such as cantata, dicta, etc. Thus, to quote Rosier, “The rule-governed nature of language-functions is to be found not only in the common usage but also in those ‘authorized’ variations. It is precisely this principle that Bacon will put to work at the semantic level when he conducts his analysis of Signs [c. 1267]. Beyond the ordinary usage of the sign, derivable from its institution, the speaker always has the liberty to use it in the translated way, the variation being in the majority of cases explainable and for this reason comprehensible by the listener. In other words, language is for man an instrument, a means. This voluntarist/instrumental conception is to be seen likewise in the context of Bacon’s treatment of the magical power of words” (Rosier-Catach 1997, 73–74).
