Logos gives design information. Without logos, design is just pretty and left without importance. Sure pathos provides emotion, but without logos there's nothing to support why that feeling is provoked or better yet how to gage the level of seriousness. How serious is this issue or topic really? Logos answers that with facts and can enhance pathos. Only with logos does your persuasive design have a purpose.
Examples of Rhetoric
from a serious of the seven deadly sins,
PRIDE is being personified
hyperbole of an egg
pun of a forest fire
antithesis; the top one uses language, by saying "industrial metal" is a therapy for pain
and the second example shows a lobster cooking rather than being cooked
irony; flowers are usually used to depict something sweet
and nice but instead depicts a derogatory word
parody; shows Elvis as Duchamps' Mona Lisa parody
(woah double paraody)
metaphor for stress
Documentation of Bike Ride Through the River Market
Riding a bike is different than going by foot because you're cruising past everyone else at a fairly fast pace speed, all you're senses are still open but you only pick up strong smells and loud sounds because everything around you is happening in a moments notice. The people walking around me were able to engage in with everything in high detail. Riding around the weekly farmer's market, I was intoxicated by the smell of bbq, coffee, and curry. Not all at once, but when I rode past their sources of smell it masked everything else. It's the more potent smells that stick out and linger with a biker. I heard a crowd of people in various conversations, possibly barging prices or thrilled at $1 containers of fresh strawberries. I heard a saxophone player playing with a jazz tone then a guitar player with a country more southern vibe. There's a lot going on and plenty to look at during a farmers market but the things that stuck out to me the most where the bright colors, children, and overall happiness in the atmosphere. Of course the fresh fruits, vegetables, herbs, and plants provided nature's beautiful colors but there also was a train made out of recycled colorful bins. There were a few more than trilled young kids riding inside them. Almost immediately afterwards, I saw a little girl getting her face painted different hues of purple with hints of other cool colors. I don't recall seeing anyone upset or angry, there was a mutual understanding of happiness in the air. Riding inside of a vehicle, you're only aware of the senses around you or within your car. Of course you can see what's going on through your windshield with the occasional glance in your rear view mirror, put a driver must remained focused primarily on the road.
