SECTION 1: Basic Components/Formal Fallacies/Validity/Strength Flashcards
What reflects strong critical thinking?
In any event, our purpose is to better understand the relevant issues so that we may make an informed decision on the topic.
Propositions
Statements that are true or false.
Non-propositions
Sentences that are not statements about matters of fact. They do not make a claim to be true or false.
Simple-Propositions
Have no internal logical structure, meaning they are true or false on their own.
Complex Propositions
Have internal logical structure, meaing they are composed of simple propositions.
Premise
The claims, evidence, ideas, and so forth intended to support the conclusion.
Conclusion
The claim that the whole argument is intended to support or demonstrate or prove.
Affirming the Consequent
Taking the true statement and assuming the converse form would be true as wel.
Denying the Antecedent
Inferring the inverse from the original statement.
Deduction
Arguments where the premises guarantee or necessitate the conclusion.
- Truth
- Validity
- Soundness
Truth
A true proposition accurately represents reality
Validity
In a good deductive argument structure, true premises would make the conclusion necessarily true. (If not invalid structure.)
Soundness
A deductive argument is sound if it has a valid structure and all its premises are true. (If an argument is deductive but has either an invalid structure or at least one false premise, then it is an unsound argument.)
Induction
Arguments where the premises make the conclusion probable
- Truth
- Strength
- Cogency
Truth
propositions are true if they ccuratley represent what is the case, otherwise they are false.
