This Book Is A Selection Of Published Papers In Philosophy Of Language By Michael Devitt, Accompanied By Many New Footnotes And Postscripts.

Those Uses Are Explained By A Unified Causal Theory: A Term's Reference Is Largely Fixed In An Object By A Causal Link Between The Person And The Object When It Is, Or Was, The Focus Of That Person's Perception.

So, A Related Theme Is The Rejection Of The Direct Reference View That The Meaning Of A Name Is Its Bearer-- Provided By Publisher.
