  The recapture relationship is an important element to any understanding of
the connexion between different systems of logic. Loosely speaking, one system
of logic recaptures another if it is possible to specify a subsystem of the
former system which exhibits the same patterns of inference as the latter
system. In particular if a relationship of this kind can be shown to exist
between a non-classical logic and classical logic, the non-classical system is
said to exhibit classical recapture. This has been invoked by several
proponents of non-classical logics to argue that their system retains classical
logic as a limit case, and is therefore a methodologically progressive
successor to classical logic. In this paper I advance and defend a new and more
precise account of recapture and the character of its reception by the
proponents of the recapturing system. I then indicate some of the applications
of classical recapture which this account makes possible.
