Statements
Any declarative statement that is either true or false. Statements are either premises or conclusions.
Premise(s)
Statement(s) allegedly providing the defense.
Conclusion
The statement allegedly being defended.
Note about Arguments
No argument can have more than one conclusion. Of course, sometimes we do find passages with more than one conclusion. There are two types of cases: (1) when more than one conclusion is drawn from the same set of premises (i.e., when the same premises contain two different arguments), (2) when we chain arguments together so that a single statement serves as both a premise and conclusion.
Deductive Validity
A deductively valid argument is such that it is not possible both for its premises to be true and its conclusion to be false
