The process of reasoning starting with a given set premises and drawing a conclusion from them is called Deductive reasoning. It basically goes from general to specific. Starting with a given set premises and drawing conclusions from them. Theconclusions are only as valid as the premises that are used and it only takes one false premise to produce a false conclusion. A valid deductive argument is one whose truth necessarily follows from the starting premises and it is sound when the argument is valid and all of its premises are true other wise it is considered unsound.
