Two Pictures of Conversation: Thought Transfer and Common Ground
The idea that understanding rests on shared thoughts is an old one.
Augustine described signs as transmitting to another person’s mind what is in the mind of the sign-giver. Locke, in 1689, contended that language’s purpose is the transfer of thoughts or ideas from one person to another.
Stalnaker’s common ground offers a different image: information shared by the speakers in a conversation rather than a parcel handed across.

Take
The transfer picture is flattering because it makes understanding sound like delivery: if the thought arrives intact, communication has succeeded.
Pushback
Common ground is less romantic. It asks whether speakers share information, not whether one mind has copied another.
