Kenneth Burke in A Rhetoric of Motives: Rhetoric is the use of words by human agents to form attitudes or to induce actions in other human agents. 2. Rhetoric and Human Life and Actions According to these definitions, human life is closely related to rhetoric, since human are the agents of rhetoric by using symbols to communicate and persuade, which would cover most of the behavior in human life. Kenneth Burke conclude that: “Man is the symbol using, making, and mis-using animal, inventor of the negative, separated from his natural condition by instruments of his own making, goaded by the spirit of hierarchy, and rotten with perfection.” Martin Heidegger also stated that “language is the house of being”. Therefore, human beings are rhetorical animals, and almost all kinds of behaviors in human daily life, including thinking and perception, verbal and non-verbal behaviors, can be interpreted rhetorically as long as they contain meaning and the intention to influence others or the self.
