According to Bitzer, rhetoric is pragmatic because it comes into existence for the sake of something beyond just itself. The way it functions is it produces action or change in the world. Rhetoric produces action by persuading people to commit to certain actions based on the teachings of that rhetoric. This relates to his system of activity because thought produces action.
Rhetoric is situational because it refers to a set of circumstances that involve at least one person that is communicating to modify the perspective of another.
Exigence is when a situation is urgent, imperfections come from it. Rather than taking the time to do it right, it is rushed. It is important to a rhetorical situation because it might cause some miscommunication if it is not properly outlined.
In a rhetorical situation, exigence is important because when persuading, it is important to have your message clear and correct. if there is error due to being rushed, then the message is ruined. Audience is important because in these persuation situations, if you don’t understand your audience, you won’t know how to speak to them. Constraints are important before the rhetorical situation because you have to plan your way around them accurately to effectively overcome them.
A passage I think I will use in my major assignment is any of the ones outlining rhetorical situations facing audience. I believe those two things are the most important regarding rhetoric.
