 Character/Content  Since Kaplan’s work on indexicals and demonstratives, (Kaplan 1989) it is commonplace to distinguish between the character of an expression and the content of an utterance of an expression. For example, the character of the word ‘I’ in English doesn’t change from context to context, although the content does. Knowing the character of a sentence like ‘I am a philosopher’ doesn’t imply knowing the content of a particular utterance of that sentence; for the latter, you need to know the ‘semantic’ context of the utterance. Character is a property of linguistic expressions (types); content is a property of utterances —sentences-in-context; tokenings of them.
