Directionality and the Reductive Link

This stems from some pre-theoretic descriptions, the bridge law interpretation in Nagel, identity-theories in the philosophy of mind, it is Moulines candidate for an amendment of semantic models and it occurs in New-Wave reductionism as a candidate for grounding smooth reductions . 

This is the formal characterization of bridge-laws in Nagel s model. 

This is the minimal condition for derivability which is considered by Richardson and Nagel as figuring in bridge-principles. 

This and other analog relations underlie new-wave reductionism and structuralist versions of reduction. This covers weaker syntactic forms of bridge-law interpretations (c/. van Riel 2011).
