{ "item_title" : "Translation, Reduction and Equivalence", "item_author" : [" David Pearce "], "item_description" : "Contemporary epistemology and philosophy of science devote a central place to questions of the following sort: When are two conceptual frameworks equivalent? Under what conditions is one scientific theory reducible to another? This essay attempts to reach a clearer grasp of these issues by providing a logical analysis of intertheory translation and reduction. Taking first order logic as a starting point, several classical theorems on definability and interpolation are generalised so as to obtain a model-theoretic characterisation of some basic types of reductive relations between theories. This account is later extended by adopting a very general and powerful semantical framework inspired by abstract logic. In this setting it is shown how a richer class of intertheoretic relations can be defined, and how the structuralist approach to reduction, developed by Sneed and Stegmüller, can be critically evaluated.", "item_img_path" : "https://covers2.booksamillion.com/covers/bam/3/82/048/444/3820484442_b.jpg", "price_data" : { "retail_price" : "58.95", "online_price" : "58.95", "our_price" : "58.95", "club_price" : "58.95", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
