PHIL 3 Lecture Notes - Lecture 2: False Premise, Deductive Reasoning, Counterexample
Document Summary
Truth value analysis - determines if the information in the premise is accurate, correct, or. Sometimes what counts as evidence is controversial. Logical analysis - determines the strength with which the premises support the conclusion (valid or invalid argument) Use logic to draw conclusions, logical analysis is important because its relevant in every subject the premises and true premises make it impossible for the conclusion to be false. Deductive argument - one which is claimed that: the conclusion follows necessarily from. Inductive - premise probably backs up the claim. Logical analysis tells us whether a deductive argument is valid or invalid. Valid deductive argument : true premises make it impossible for the conclusion to be. Better - an argument is valid if it is (logically) impossible for the premises to be. Deductive arguments: validity and soundness false true and the conclusion to be false.
