PHIL 2100 Chapter Notes - Chapter Chapter 3: Fallacy, Keystone Pipeline, Logical Form
Document Summary
Devising an argument show your audience that a statement or claim is worthy of acceptance. Evaluating an argument see whether the argument shows the statement really is worthy of acceptance. Good argument argument shows that the statement is worthy of acceptance: logical validity/strength, proper structure, and true premises. Bad argument argument fails to show that the statement is worthy of acceptance. Types of argument: deductive intended to provide and is potentially capable of providing logically conclusive support for its conclusion, valid argument: deductive argument that succeeds in providing conclusive support for its conclusion. Valid is not a synonym for true. It has the logical structure that guarantees the truth of the conclusion if the premises are true. Truth-preserving: characteristic of a valid deductive argument where logical structure guarantees truth of conclusion if premises are true. Impossible for premises to be true but conclusion false because conclusion follows logically from the premises. Sound: deductively valid argument that has true premises.
