WHAT IS A DEDUCTIVE ARGUMENT?

 

A deductive argument is a logic construct with two or more premises and a conclusion where if the premises are true then the conclusion must also be true. 

In philosophy, if the truth of the conclusion is fully established by the premises, then the argument is called valid.

Deductive argument: 'All dogs have four legs, John's pet is a dog, therefore John's pet has four legs. '

 A deductive argument establishes a conclusion to be true by stating two or more true premises that lead to the conclusion being true.

In a simple deductive logic argument, you'll often begin with a premise, and add another premise. Then, you form a conclusion based on these two premises. This format is called “premise-premise- conclusion.

With this type of reasoning, if the premises are true, then the conclusion must be true.

 Logically Sound Deductive Reasoning Examples: 

All dogs have ears; golden retrievers are dogs, therefore they have ears.

 All racing cars must go over 80MPH; the Dodge Charger is a racing car, therefore it can go over 80MPH.
