Use–mention distinction
In analytic philosophy, a fundamental distinction is made between the ordinary use of a term (a word, name, phrase, etc.) versus the self-aware mention of it. The distinction between use and mention can be illustrated with the English word "cheese":
The first sentence is a statement about the substance called "cheese": it is using the word "cheese" to refer to the common dairy product. The second is a statement about the very word "cheese" itself. In that sentence, "cheese" is acting as a signifier: the writer is mentioning the word without using it to refer to anything other than itself. In that case, especially without quotation marks, the mentioned word is said to be autonymous.
The use–mention distinction can sometimes be pedantic, especially in simple cases where it is obvious. However, scholars argue that many philosophical works have been misguided, or misinterpreted by others, based on a failure to understand or recognize this basic distinction.
In written language, mentioned words or phrases often appear between single or double quotation marks or in italics. In philosophy, single quotation marks are typically used, while in other fields (such as linguistics) italics are more common. Some style authorities, such as Strunk and White, emphasize that mentioned words or phrases should be visually distinct. On the other hand, used words or phrases do not carry typographic markings.
The phenomenon of a term having different references in various contexts was referred to as suppositio (substitution) by medieval logicians. A substitution describes how a term is substituted in a sentence based on its referent. For nouns, a term can be used in different ways:
The use–mention distinction is particularly significant in analytic philosophy. Confusing use with mention can lead to misleading or incorrect statements, such as category errors.
Self-referential statements also engage the use–mention distinction and are often central to logical paradoxes, such as Quine's paradox. In mathematics, this concept appears in Gödel's incompleteness theorem, where the diagonal lemma plays a crucial role.
Stanisław Leśniewski extensively employed this distinction, noting the fallacies that can result from confusing it in Russell and Whitehead's Principia Mathematica.
