These are excerpts and elaborations from my book "The Nature of Consciousness"

Case-based Grammars Either because they did not
agree with his vision of the human mind, or because they considered unnatural
the limits of his grammars, or because they devised mathematically more
efficient models, other thinkers rejected or modified Chomsky's theory. One powerful idea that
influenced many thinkers is that the deep structure of language is closer to
the essence of concepts than to the syntax of a specific language. For example,
case-frame grammar (developed in the late 1960s by the US linguist Charles
Fillmore) assumes that each sentence
represents explicitly the relationships between concepts and action. Fillmore shifted the emphasis towards
cases. Traditional cases (such as the ones used by German or Latin) are
purely artificial, because the same sentence can be rephrased altering the
cases of its constituents: Piero in Piero wrote this book and this book
was written by Piero appears in two different cases. But its role is always
the same, regardless of how we write the sentence. That role is the real
case, in Fillmores lingo. These cases are universal. They are not
language-specific. My relationship towards the book i wrote is the same in
every language of the world, regardless of how a specific syntax allows me to
express such relationship. Fillmore concluded that a universal underlying set
of case-like relations plays a fundamental role in determining syntactic and
semantic relations in all languages. In Fillmores grammar, therefore, a sentence is represented by identifying such
cases. Sentences that deliver the same meaning with different words, but that
describe essentially the same scene,
get represented in the same way,
because they exhibit the same items in the same cases. Fillmore's approach started a whole new school of thought. Drawing from the
Aristotelian classification of state, activity and eventuality, the US linguist
David Dowty proposed that the modal operators "do",
"become" and "cause" be used as the foundations for
building the meaning of every other verb.
Within a sentence, the various words have "roles" relative to
the verb. A thematic role is a set of
properties that are common to all roles that belong to that thematic role. A
thematic role can then be seen as the relationship that ties a term with an
event or a state. And this allows one to build a mathematical calculus (a
variant of the lambda calculus) on thematic roles. Likewise, Ray Jackendoff proposed that the meanings of
all verbs be reduced to a few space-time primitives, such as motion and
location. Back to the beginning of the chapter "Language: Minds Speak" | Back to the index of all chapters |
