Rhetorical Appeals: Logos
Transcript of Rhetorical Appeals: Logos
Three Types of Rhetorical Appeals
Commercial Example of Logical Appeal
An In Depth Look at Logos
Are ethical appeals
They bloster your creditability or your arguments
Using your audience's emotions to persuade
Uses reasoning or logic to support your argument
How is logos used in writing?
Logos is the use of arguments in your writing or speaking
What makes up an argument?
There are two ways to look at arguments
1. Statement and Proof
2. Claim and Supporting Evidence
(Everything's an Argument 74)
How is Logos used?
There are many different ways to use logos in your persuasive writing some methods may include:
Arguments of Degree
Arguments of Precedent
Arguments Involving Analogies
Types of Arguments to avoid
These are some examples of types of arguments can undermine the strength on your argument you are presenting. So avoid them in your writing.
When is Logos Used?
These are arguments of goodness or badness.
Example: If peanut butter tastes good, then peanut butter and jelly sandwiches must be delicious.
(Everything's an Argument 90)
Arguments of precedent, involve comparing things, much like analogies. From the precedent the audience should be able to infer the rational of why you are for or against something
Example: California made it illegal to use your cell phone while driving. Arizona should make it illegal to use cell phones while driving all across the state, not just in Phoenix.
(Everything's an Argument 91)
Arguments involving analogies use an extended comparison to argue their point. Similar to precedent based arguments but the comparison is much longer.
Example: We shouldn't train the new coordinators on Saturday nights because it makes them feel overwhelmed and like they don't know what they are doing. It is almost like they are babies who are learning how to swim and we just throw the baby in the deep end of the pool. The most likely result will be the baby doesn't learn to swim but develops a fear of water.
(Everything's an Argument 90)
Slippery Slope Arguments
Either / Or Arguments
This is the type of argument that if this happens then it will lead to that. In order to prevent that, you must not allow this.
Example: By feeding your dog fast food, he will develop heart disease and become fat, so don't feed your dog fast food.
(Weida and Stolley 8)
As the name describes these are arguments that support themselves by using evidence that goes in a circle.
Example: Hearsay is defines as an out of court statement used to prove the truth of the matter asserted. This is hearsay because it was written out of court by J.C. Longstreet.
(Weida and Stolley 17)
(Weida and Stolley 14)
(Weida and Stolley 18)
These types of arguments provide the audience with an ultimatum or only two options.
Example: You can either finish the prezi on time or you can receive no credit for the work you did.
Genetic fallacies are arguments that make the point on a person's character or origin rather than the actual fact itself.
Example: Wearing nike brand clothing is bad because they support slavery.
Logos is used whenever a fact or statistic is mentioned to support your claim
Most often arguments of the law can be considered arguments using logos. Like Mark O'Mara, he appealed to the jurors' logical side to show the lacking of evidence presented by the prosecution. His argument was successful as the jury returned a verdict of not guilty.
