Explain Valid Arguments.

When some statement is said on the basis of a set of other statements, meaning that this statement is derived from that set of statements, this is called an argument. The formal definition is “an argument is a list of statements called “premises” (or assumptions or hypotheses) which is followed by a statement called the “conclusion.”

A valid argument is one in which the premises imply the conclusion.

1) It cannot have true premises and a false conclusion.

2) If its premises are true, its conclusion must be true.

3) If its conclusion is false, it must have at least one false premise.

4) All of the information in the conclusion is also in the premises.
