Philosophy Lexicon of Arguments

Mention philosophy: the mention of linguistic objects must be distinguished from their use. This distinction is sometimes difficult when symbols are partly used and partly mentioned within logical formulas. One simple case of a mention of a word or phrase is the quote. See also object language, metalanguage, quote, reference, occurrence, type, token.
