François Recanati presents his theory of mental files, a new way of understanding reference in language and thought. Linguistic expressions inherit their reference from the files that we associate with them, which are classified according to their function, which is to store information derived through certain types of relation to objects. Mental Files raises some great issues and investigates some major problems with lucid and rich arguments. Hence, the book is more than worth reading, and its lucidity both induces agreement and helps at clarifying one's dissent.
