Making & Supporting

Logical Arguments with

Claim/Evidence/Warrant


Much of this class will be focused on a central skill of both college and workplace writing: making an argument.

More immediately, you will be using the skills you learn here for the rest of the semester -- so it makes sense to devote the time to mastering them now.

An argument generally involves three elements:

 

Element
Description of Element
The Claim
What you want your readers to believe; the "point" you hope to persuade your reader of
The Evidence
What you will use to support the claim; your "proof" -- often a direct or indirect quotation from a text, but sometimes a statistic or the like
The Warrant
A general principle that explains why you think your evidence is relevant to your claim

You might want to think of making a point with evidence in a paper as a conversation with a friend in which you attempt to persuade that friend of a particular perspective.

Listed below are the questions your friend might ask as you tried to make your argument, followed by the element described above that would answer your friend's questions:

 

Question from Friend Element

 

What are you trying to demonstrate?

The Claim

What proof do you have?

The Evidence

 

Why do you think that your proof is relevant to your claim?

 

The Warrant

 

You must always state both your claim and your supporting evidence explicitly; one without the other is either pointless evidence or an ungrounded opinion.

 

 Taking a fairly straightforward example:

I know it rained last night because the streets are wet.

Element
Text
The
Claim


What are you trying to demonstrate?



I know it rained last night

The Evidence

What proof do you have?

 

the streets are wet


It would be difficult to take issue with this claim-evidence relationship.

But most evidence-claim relationships are not so simple.

Most evidence-claim relationships require an additional element: a
warrant.
