Lesson 5: Rhetorical Analysis



We are now going to switch gears a little bit and investigate rhetorical strategies in the so-called rhetorical triangle - ethos, pathos, and logos. Rhetorical strategies are methods used to persuade an audience. They were outlined over 2,000 years ago in ancient Greece, but they remain valid and powerful today. They can be used in all forms of communication, including speech, writing, video, and imagery. They are used in every field of inquiry and study, including energy and sustainability. Understanding these strategies can be an important aspect of critical analysis because skilled communicators are very good at using them to persuade an audience that their assertions are valid. Rhetorical strategies are also important to understand if you are to be an effective communicator.

We then investigate greenwashing, which is an attempt by companies to convince audiences that the company acts more sustainably than it actually does.

Finally, you will be introduced to the three types of lies, and an emerging field of study and application called "Behavioral Economics." Behavioral Economics is a branch of economics that seeks to understand why people act in ways that don't fit into the standard, neoclassical model of economics. Neoclassical Economics is the type of economics that most economists, policy-makers, and academics use, and is almost certainly the one that you learned in Economics class. Buckle up - this should be interesting!
