Final Flashcards
Argument
A claim supported by data or reasoning
Argument (Toulmin)
Movement from data, through a warrant, to a claim
Argument (Warnick and Inch)
A set of statements in which a claim is made, support offered for it, and there is an
effort to influence someone in a context of disagreement
Claim
Explicit appeal produced by an argument, must be controversial
Formal logic/deductive reasoning
Makes broad statements about a category, applies those characteristics to specific elements, if specific rules not followed, argument is flawed
Informal logic/inductive reasoning
Go beyond available data, conclusions may be tentative
Warrant
Often unspoken, expresses the assumptions or reasoning
used by the arguer to link the data to the claim.
Cause to effect
Attributes power to an object, specifies nature of effect, predictive
Effect to cause
Nature of cause that brought about an effect, reasons backwards
Sign/coexistential
Interprets meaning of symptoms, claims that some object possesses attributes of which clues are symptomatic
Generalization
What is true of items in representative sample will be true of larger group
Parallel Case/Example
Statement about an object, similar to second object in same category, what is true of first object will be true of second
Analogy
Relationship between two items, assumes similar relationship between another pair of items, makes relationship explicit
Classification
Conclusion about a class of things, what is true of these items will be true of unexamined one
Authoritative
Concern the quality of source from which data are derived
Motivational
Carry data to claim by addressing the inner motivations of audience
Critiques of argument of parallel case
- Are the two objects being compared truly of the same class?
- Are the points of similarity relevant and significant?
- Are the two objects being compared similar in a sufficient number of respects?
- Are dissimilarities noncritical to the conclusion?
Critiques of argument of generalization
- Are there enough examples to reliably predict a general trend of characteristics?
- Are the example relevant to the claim of generality?
- Are the examples typical or representative of the class of objects about
which the generalization is made? - Are examples that counter the claim made in the generalization noncritical?
Critiques of arguments of cause
- Necessary condition—A necessary condition is one that must be present for
the effect to occur. - Sufficient condition—A sufficient condition ensures that the effect will occur;
the presence of a sufficient condition guarantees the presence of the effect. - Is the cause capable of producing the desired effect?
- Is the cause necessary and sufficient?
- Might some other cause offset the desired effect?
- Correlational argument—Two events or phenomena are correlated when an
increase or decrease in one is related to an increase or decrease in the other.
Critiques of argument of sign
- Is the sign relationship constant?
- Is the sign reasoning cumulative?
- Are there contrary signs?
Critiques of argument of authority
- Is the source well-qualified to speak on the issue?
- Has the source had access to firsthand information about the issue?
- Is the source unbiased?
- Is the testimony consistent with other sources of information?
Enthymeme
Syllogism with step missing
Syllogism
Argument with three parts
Polysemy
Way in which words can have multiple meanings
Literal analogy
Compare two things that are similar on their face, opponent only has to come up with one dissimilarity
Figurative analogy
Compares two dissimilar things, weak because things compared are fundamentally different
Rhetoric
Capacity to see all the available forms of persuasion in a given argument
Jeremiad
Type of speech where blame assigned to audience, insist they take action
Prima Facie
Based on first impression, accepted as correct until proven otherwise
Enumeration
Form of induction by which people agree to bolster argument
Apologia
Speech of self defense, admit to what you’ve been accused, say they were right
Field of argument
Contexts in which argument occur that develop standards surrounding evidence
Ad hominem
Attacking a person rather than the evidence they present
Qualifier
Modification of amount that author believes in argument
Post hoc ego propter hoc
Fallacy that confuses timing with cause, because one thing followed another, the first caused the second
