This is used way more than we think
Found Arthur Schopenauer's book "The Art of Controversy" on the web in its entirety. In both English and its original German.
Some chapter headings:
Generalize your Opponent's Specific Statements
Conceal Your Game
Make Your Opponent Angry
Generalize Admissions of Specific Cases
Claim Victory Despite Defeat
Generalize the Matter, Then Argue Against it
State a False Syllogism
Find One Instance to The Contrary
Turn The Tables
Anger Indicates a Weak Point
Persuade the Audience, Not The Opponent
Put His Thesis Into Some Odious Category
Bewilder Your Opponent by Mere Bombast
Sound like some JUsers? Or some political talking heads? Hmmm... coincidence? I think not. I think ol' Schopenauer gets used all the time these days.
