There are two methods for reasoning one is Inductive, as seen in the example above the other method is Deductive. Inductive is an analogical reasoning, using examples to prove something true. The example above is a humorous exaggeration of how Inductive reasoning is used by stating that because he exist, therefore he is human. Then looks at the sharpener as something existing to categorize it as human as well. In Inductive reasoning the theories may be right, or wrong, but are debated using examples.
