ESGS Logical Fallacies

Argumentum Ad Nauseam


Repeating the same argument over and over again, without supporting it or repeating the same arguments without adding new ones. Note that the assertion can be correctly supported but that the fallacy resides in the perpetual repeating.


This fallacy is based on the incorrect belief that people will finally accept an assertion as true because they hear it repeatedly. Brain-washing is expected. Works better on prisoners than on free citizens.


"Delenda est Carthago". (Carthage must be destroyed)
Caton the Elder ended all of his speeches by these words, whatever the subject was.




This fallacy is a two-edged sword: some people will get sick of hearing the same thing over and over again, and will react by believing the opposite of what you say.
If your opponent becomes repetitive, point it out after having refuted his arguments a few times.
