The goal of "
eristic" argument is to appear to "
always be right". Aristotle had disdain for those who used these (invalid) arguments in order to make money from others.
An 1818 book by the title
The art of always being right by German philosopher Arthur
Schopenhauer details "
eristic" (and other) ways of (valid or invalid) reasoning and provides ways or "
tricks" to use in such arguments.
The German title was
"Eristische Dialektik: Die Kunst, Recht zu behalten;" ≈ "Eristic dialectic: The art of being right". The Greek word "
dialectic" meant a "
discussion" as in a "
verbal interchange".
