“To say that an author is illogical is to say that **he has committed a fallacy in reasoning**. In general, **fallacies are of two sorts**. “There is the **non sequitur, which means that what is drawn as a conclusion simply does not follow from the reasons offered**. “And there is the occurrence of **inconsistency, which means that two things the author has tried to say are incompatible**. “To make either of these criticisms, **the reader must be able to show the precise respect in which the author’s argument lacks cogency**.” ([Location 2322](https://readwise.io/to_kindle?action=open&asin=B004PYDAPE&location=2322)) --- **Tags** -- [[quotes]], [[reading-books]], [[analytical-reading]], [[simple-logic]], [[non-sequitur]], [[consistency]] **Source** -- [[20250103084100 - B - How to Read a Book]]
