Those of you who have read my posts on logic, and particularly my posts on logical fallacies, should be familiar with how you can call someone out when they make fallacious or spurious arguments against you. This was my own motivation in immersing myself in the field of logic for years, the ability to become a human logic machine. This is its own reward, the ability to use reason as a rapier can be exhilarating and bring great intellectual satisfaction, however logos alone is not an effective tool for the rhetorician.
In ancient Greece there was a group of teachers that were called the sophists, they were teachers of many things but are perhaps most renowned for teaching the tools of convincing rhetoric. Depending on who you read on the topic of sophism, Plato for instance derided them for using their knowledge to their own ends rather than seeking justice and truth, you may have a different picture. The modern meaning of the term, has come to mean one who uses the tools of logic and rhetoric to deceive someone in a debate. The term “sophistry” has come to be defined as using sophisms for subtle and deceptive argumentation or reasoning.
