Sophistry

 
Sophistry means creating an argument that seems plausible, but is fallacious or misleading, especially one devised deliberately to be so; the art of using deceptive speech or writing; cunning or trickery.

Sophism can mean two very different things: In the modern definition, a sophism is a confusing or illogical argument used for deceiving someone. But in Ancient Greece, the sophists were a group of teachers of philosophy and rhetoric and the term sophism originated from Greek sophistēs, meaning "wise-ist", one who "does" wisdom, one who makes a business out of wisdom (sophós means "wise man").
