ABSTRACT
Brandom’s inferentialist semantic theory has three levels, which together comprise what he terms the “ISA approach”. The first is the inferential level which invokes inferential relations among repeatable sentence types (such as the sentence type: “Mandela is a lawyer”). The second is the substitutional level, which invokes indirect inferential relations between subsentential repeatable expression types (such as the singular term type: “Mandela”). The third is the anaphoric level, which invokes indirect inferential relations between unrepeatable tokenings (such as the demonstrative tokening “that”) and repeatable expression types.
