ABSTRACT
The relationship between reasoning and language is a complicated one. Sometimes it is not clear how to distinguish between reasoning deficiencies and problems arising from careless or inept use of language. If in reading a sentence we understand what the sentence says explicitly, but fail to understand what it implies, is that a failure of language comprehension or of reasoning? If I claim to believe both of two contradictory statements, is it more reasonable to assume that I must misunderstand at least one of the statements or that I am being illogical?
