The definition of Deductive argument and Inductive argument

"Arguments can be classified in terms of whether their premisses (if true) would provide (1) conclusive support, (2) partial support, or (3) only the appearance of support (that is, little or no support at all).


When we say that the premisses provide conclusive support for the conclusion, we mean that if the premisses of the argument were all true, then the conclusion, would also be true. Arguments that have this characteristic are called (correct or valid) deductive argument.


When we say that the premisses of an argument provide partial support for the conclusion, we mean that if the premisses were true, they would give us good reasons-but not conclusive reasons-to accept the conclusion. That is to say, if the premisses were all true, the conclusion would probably be true but just might be false. Arguments of this type are called (correct) inductive argument."
