Study Notes
Identifying Arguments
- Premise indicators: since, therefore, because, so, for, hence, as, thus, given that, implies that, seeing that, consequently, for the reason that, it follows that
- Conclusion indicators: so, therefore, hence, thus, consequently, it follows that
- Not all sentences with these indicators are arguments; understanding of the sentence is necessary to determine if an argument is present
- Ask: Is there a statement someone is trying to establish as true or explain why it is true by basing it on some other statement?
Arguments and Explanations
- Arguments: statements with premises providing reasons (support, evidence) for accepting the conclusion
- Goal of an argument: to establish that the conclusion is true
- Example: citing studies from CDC and NIH to establish that obesity rates are rising in the U.S.
- Standard form: clearly distinguishes premise from conclusion, showing how the conclusion is supported by the premise
Explanations
- Goal of an explanation: to establish why a statement or claim is true, not just that it is true
- Example: Socrates was a man, all men are mortal, therefore Socrates was mortal
- Essence of the argument: if A=B, and B=C, then A=C
- Deductive reasoning: starting from general premises, drawing a specific conclusion containing no more information than the premises
- Correctly formulated deductive argument: if premises are true, the conclusion must be true; rejecting the conclusion means rejecting logic
