PHIL 1021 Lecture : Prelim 1 Notes
Document Summary
Direct course aims: gain knowledge of central concepts of logic such as, deductive validity. Inductive validity: soundness, tautology, gain knowledge of techniques for statements, develop understanding of good vs. bad reasoning, scientific reasoning. Indirect course aims: enhance ability to articulate ideas, enhance ability to detect defective reasoning. A statement is a sentence that is capable of being either true or false. An argument is a group of statements, one of which (the conclusion) is suppose to be supported by the remaining statements (the premise). An argument is deductively valid if and only if it is impossible for all its premises to be true and its conclusion to be false. Sound- an argument is sound if and only if (1)it is deductively valid and (2) all of its premises are true. Inductively valid- an argument is inductively valid if and only if its conclusion is probably true if all of its premises are true.
