Deductive Reasoning





Deductive Reasoning Definition: Deductive Reasoning assumes that the conclusion must be true because it follows the statements of the premises. If you deny the conclusion, that means that one of the premises must be untrue. As long as you use the word "all" correctly in the premise, the conclusion must be true, and thus valid.

Examples: All creatures need water to live, and I am a creature. This concludes that I need water to live. Because both premises are true, the conclusion is true.

All Monkeys like bananas, and Lucy is a monkey. Therefore, Lucy likes bananas.
