PHI 103 Lecture Notes - Lecture 6: Enthymeme, Syllogism
Document Summary
How to discuss an argument"s content, if you have a predicate argument (a syllogism). When we evaluate arguments, we are interested in both the argument"s form and its content. We evaluate its form in terms of validity. We evaluate its content in terms of truth. We need to examine each statement in an argument individually to determine whether it is true or false. This depends, in part, on the type of statement we have. For categorical syllogisms, we have six types of statements. We have the four categorical statements; (1) all s are p (2) no s are p (3) some s are p (4) some s are not p. And we have two singular statements: (1) s is p (2) s is not p. The first premise of the argument says this: all valid arguments are arguments. S" stands for the subject of the statement while p" stands for the predicate.
