Singular Reference The Turn to Propositional Thinking

The ability to refer to objects - singular reference - is arguably the decisive innovation on the way to human propositional cognition. This article argues that object individuation requires singular reference because basic singular terms, namely spatial indexicals, provide a symbolic frame of reference for object individuation. The authors suggest that singular reference is intrinsically connected to essential characteristics of propositionality: among other things, it guarantees the situation-independence of meaning, allows for the distinction between truth and falsehood, and enables us to think about possibilities. The authors sketch how singular reference gives rise to the development of predication, the powerful logical tool of quantification, and forms the basis for differentiating between belief and desire.
