You say that like it’s a bad thing…
“There is in philosophy a very old name for the view that the point of argument is to persuade; it’s ‘sophistry’. One of the old Platonic points is that if you take argument to be primarily for the purpose of persuading people to its conclusion, what you are really saying is that reasoning is primarily a way to impose one’s will.” — Arguments and Persuasion
The thing is, even if politicians and managers today believed this – that it’s mere sophistry to define argument as persuasion – they’d say “Ah, sophistry! I didn’t know there was a word for that. Go and hire me a sophist right now! No, two! Two sophists! Get the cheapest you can find, and spare no expense!*”
*That’s how politicians and managers talk.
