Notes on Kenneth Burke: "Intelligence is defined as the property that causes a sentient being to generate and respond to symbol systems; rhetoric is the process an individual uses while intentionally generating symbols in order to elicit responses from other individuals."

Kenneth Burke was a rhetorical theorist, philosopher, and poet. Many of his works are central to modern rhetorical theory: A Rhetoric of Motives (1950), A Grammar of Motives (1945), Language as Symbolic Action (1966), and Counterstatement (1931). Among his influential concepts are "identification," "consubstantiality," and the "dramatistic pentad." He described rhetoric as "the use of language as a symbolic means of inducing cooperation in beings that by nature respond to symbols." 

For Kenneth Burke, intelligence and rhetoric use are inseperable, and are the abilities which set humans apart from other animals.  Intelligence is defined as the property that causes a sentient being to generate and respond to symbol systems; rhetoric is the process an individual uses while intentionally generating symbols in order to elicit responses from other individuals. For Burke, "rhetoric is a rhetor's solution to perceived problems..." others might experience (194). -  http://sites.google.com/site/nightfly/kennethburke
