Rhetological Fallacies: Errors and manipulations of rhetorical and logical thinking.
Useful and deeply amusing chart of errors in rhetoric and logic by David McCandless.
Each error has a symbol along with a brief explanation.
These symbols really should appear in Unicode. 😉
Or at least have a TeX symbol set defined for them.
I have written to ask about a version with separate images/glyphs for each fallacy. Would make it easier to “tag” arguments.
