Master List of Fallacies

Formal 2018-04-03T15:03:55+00:00

A non sequitur (Latin for “it does not follow”), in formal logic, is an invalid argument. In a non sequitur, the conclusion is either true or false, but the argument nonetheless asserts the conclusion to be true and is thus fallacious. While a logical argument is a non sequitur if, and only if, it is invalid, the term ‘non sequitur’ typically refers to those types of invalid arguments which do not constitute logical fallacies covered by particular terms (e.g. affirming the consequent). In other words, in practice, ‘non sequitur’ refers to an unnamed logical fallacy. Often, in fact, ‘non sequitur’ is used when an irrelevancy is showing up in the conclusion. It is the act of introducing a neutral topic to divert attention away from the main topic of discussion.

Superior Knowledge 2018-04-03T15:03:48+00:00

The Superior Knowledge fallacy occurs when the student of scripture resorts to textual emendations in order to explain some difficult passage. The student may dismiss prima facie (literally, “at first view”) evidence of the text and fill in the gaps with insufficient knowledge to make sense of what they read. This fallacy is most often committed by evangelical scholars and new believers.
