Valid: an argument is valid if and only if it is necessary that if all of the premises are true, then the conclusion is true; if all the premises are true, then the conclusion must be true; it is impossible that all the premises are true and the conclusion is false. ... If this is possible, the argument is invalid.

From Wikipedia, the free encyclopedia. Deductive reasoning, also deductive logic, is the process of reasoning from one or more statements (premises) to reach a logical conclusion. Deductive reasoning goes in the same direction as that of the conditionals, and links premises with conclusions.

If a deductive argument is invalid, then it must also be unsound. If an argument is invalid, then it must have at least one false premise. ... If the premises and conclusion are all false, the argument must be invalid. Some invalid arguments have true premises and a true conclusion.

Deductive reasoning uses given information, premises or accepted general rules to reach a proven conclusion. On the other hand, inductive logic or reasoning involves making generalizations based upon behavior observed in specific cases. Deductive arguments are either valid or invalid.

The primary difference between logic and reason is that reason is subject to personal opinion, whereas logic is an actual science that follows clearly defined rules and tests for critical thinking. Logic also seeks tangible, visible or audible proof of a sound thought process by reasoning.

A deductive argument is said to be valid if and only if it takes a form that makes it impossible for the premises to be true and the conclusion nevertheless to be false. A deductive argument is sound if and only if it is both valid, and all of its premises are actually true. ...

 Reason and Impartiality become the basic prerequisite for morality as one is expected to be able to deliver clear, concise, rightful, and appropriate judgments made out of logic and understanding in an unbiased and unprejudiced manner while considering the general welfare to accurately concoct moral decisions.

A deductive argument is an argument that has the absolute conclusion. This argument has both a true conclusion as well as true premise. A non-deductive argument is an argument is providing a plausible conclusion. This arguments contains a conclusion that may be false even though the premises are true.

Deductive reasoning, unlike inductive reasoning, is a valid form of proof. It is, in fact, the way in which geometric proofs are written. Deductive reasoning is the process by which a person makes conclusions based on previously known facts.
