Reductive Dependence as Grounding Epistemic and Pragmatic Differences

3 Reductive Dependence as Grounding Epistemic and Pragmatic Differences 

How a theory of Fregean sense should look like is a question that has to be settled on independent grounds. Thus, what ultimately is the correct version of the definition of reduction will, hopefully, fall out of our correct semantic theory. Just like the question of what theories basically are will decide, to some extent, which version of a characterization of theory-reduction is more appropriate - a syntactic or a semantic one - a theory of what Fregean senses basically are will ultimately decide how to account for the features mimicked by the notion of a property structure. Thus, as long as they preserve the stmcture of the characterization given above, 

We have defined an appropriate core notion of reduction, which captures the characterizations offered before, and three important derivative notions. The core notion matches the job description, and it is motivated by the solution to the puzzle offered in Chap. 3 as well as by the alleged similarity between mechanistic and reductive explanation. 

How can we reconcile diversity and directionality with strong unityl 

4 A core notion and derivative notions of reduction can be explicated the exphcation fits paradigmatic cases, is coherent (solves the puzzle) and satisfies an intuitive job-description.
