Presentation Transcript
Propositions l.jpg

  • A proposition is the declarative statement that an advocate intends to support in the argument.

  • Some propositions are stated formally, some are stated informally, and some are implied.

  • Propositions usually answer questions: such as What should be done about inflation?

  • Is the same thing as the claim in the Toulmin model, or a conclusion in classical model.

Assertions l.jpg

  • There is a difference between a proposition, claims and an assertion.

  • An assertion is a claim or proposition with no support.

  • Assertions tend to weaken arguments due to their lack of support.

Responsibilities of advocates l.jpg
Responsibilities of Advocates

  • Anyone who argues in favor of the general proposition has the burden of proof for that proposition.

  • The burden of proof is the responsibility to provide enough evidence and reasoning to justify acceptance by a critical thinker.

  • Those who argue against the proposition have the benefit of presumption.

Slide4 l.jpg

  • Presumptions are the perspectives that the proposition should not be accepted until sufficient evidence and reasoning have been provided to justify acceptance.

Types of propositions l.jpg
Types of propositions

  • Propositions of fact – when an advocate argues in favor of accepting a statement that is something factually true, was factually true, or will be factually true.

  • A proposition of fact still requires support so it does not matter if it is good or bad.

Proposition of fact l.jpg
Proposition of Fact

  • California will suffer an earthquake of 10.0 in the next 5 years. OR:

  • Jeff Gordon is the best Nascar driver ever!

  • The advocate then provides reasons to believe the statement.

Stock issues for fact l.jpg
Stock issues for Fact

Stock issues: definition and distinction

Defines what the proposition means and does not mean

Stock Issue: criteria – establishes truth

How do we tell if something is true or not

Stock Issue: application

Arguing that criteria are being met or will be met , so proposition is true

Proposition of value l.jpg
Proposition of Value

  • You support an evaluation about something, such as how good a product is.

  • Stock issue: Value – an argument of which value or set of values is the most important in drawing a conclusion for this argument

  • Such as: vegetables are healthier than meat – set of values is taste, health, life, quality of life, etc.

Proposition of policy l.jpg
Proposition of Policy

  • Whenever you argue that some change of action should take place.

  • Many times involve public policy issues and laws

  • Policy propositions attempt to make a change in the status quo

  • Example: The federal government should institute a national health care program for all US citizens.

What are stock issues l.jpg
What are stock issues?

  • “Arguments that naturally recur in disputes over propositions of policy.” (Hollihan and Baaske)

  • Arguments that address “all” of the stock issues usually are stronger than those that don’t.

Stock issues address the following questions l.jpg
Stock issues address the following questions:

  • What is the problem?

  • How big is the problem?

  • What’s causing the problem?

  • What should be done to correct the problem?

  • How well will that action solve the problem?

  • Will the action create other benefits or harms?

What are the stock issues for propositions of policy l.jpg
What are the stock issues for propositions of policy?

  • Harm

  • Significance

  • Inherency

  • Plan

  • Solvency

  • Advantages

Slide14 l.jpg

  • The advocate tries to demonstrate that something is wrong that needs to be fixed.

  • The problem(s) can be existing now or in the future.

  • The problem(s) can be within people, animals, psychological, economic, environmental, organizations, etc . . .

  • Opposition would indicate that there is really nothing wrong.

Significance l.jpg

  • Shows how bad the harm is.

  • Two types of significance: qualitative and quantitative.

  • Qualitative significance shows that the harm has severe detrimental effects on whoever is harmed. (value argument)

  • Quantitative significance is concerned with how much has been effected? (factual argument)

Inherency l.jpg

  • What is causing the harm in the statusquo?

  • Two types: structural inherency and attitudinal inherency.

  • Physical and systematic causes can create problems within the status quo.

  • Such things as laws, regulations, and judicial decisions can have an effect on a status quo.

Slide17 l.jpg

  • Attitudinal inherency is concerned with the attitudes that people hold that cause the problem.

  • Attitudes are unlikely to change unless some kind of legislative action takes place.

Slide18 l.jpg

  • What you propose to do to solve the problem.

  • This stock issue is critical to the affirmative.

  • The plan can be small or large, detailed or vague in nature.

  • Make sure your plans are “realistic”.

Solvency l.jpg

  • Addresses: “How much of the problem will be solved by the plan?”

  • Some solutions don’t solve all of the problem.

  • We can’t assume that a plan will resolve the entire problem.

  • Opposition would show that the plan is unworkable.

Advantages l.jpg

  • Addresses: “What will be the benefits of adopting the plan?”

  • Similar to Monroe’s “visualization” step.

  • The opposition would address disadvantages of the proposed plan.

Methodology l.jpg

  • Start by figuring out whether the arguer is proposing or opposing a proposition.

  • Decide what the proposition is and what kind of proposition it is?

  • Keep in mind that stock issues do not come in any particular order and are rarely explicitly identified.

  • Some stock issues are not addressed in the argument.

Slide22 l.jpg

  • How well were they addressed?

  • Did the arguer meet the “burden of proof?”

  • Finally, make a judgment of whether you believe the argument was strong or weak?

Conclusion l.jpg

  • Understanding the stock issues for each type of proposition helps you make your own arguments, evaluate the arguments of others, and respond to arguments.
