WELL! In case you were wondering, chapter 14 of Everything's an Argument is about visual arguments! :O
The chapter discusses the power that visual arguments can have, whether it be strong or weak. Visual arguments take the phrase "a picture's worth a thousand words," and take it to a complete other level. Words aren't always needed in visual arguments; they can be extremely powerful with or without them. Another section in the chapter discusses how to analyze visual elements of arguments. THEN, it gets into "Using Visuals in Your Own Arguements," emotional appeal in visual arguments, visual arguments based on character. This chapter pretty much just picks visual arguments apart in their entirety, breaking them down for a better understanding of how they work, how they can be effective, etc.
The section on "The Power of Visual Arguments" held my attention the most, so I'll go a little more in depth on that one. Right away, the sections gets into important memories, horrific and not, including 9/11, Hurricane Katrina, and the 2008 Summer Olympics in Beijing. Visuals can have influence us greatly, and sometimes, they "pack more punch than words." The idea of using visuals started in ancient times in Egypt. Other examples are used to show just how pervasive visuals and visual arguments are becoming. Once graphic computers came around, production of visuals skyrocketed. In visuals, "them medium is the message" They're starting to take the stage more than words.
