Two concepts of intertheoretic reduction thomas nickles. Nickles rejects the widespread view that reductions of scientific theories are all of one basic type: special case t" does not mean simply logical consequence of t . We need to recognize at least two main kinds of reduction: reduction1. Is the achievement of postulational and ontological economy and is obtained chiefly by derivational reduction. This model is most helpful for understanding what i term domain-combining reductions. Reductions of predecessor theories by their successors ( domain-preserving reductions), on the other hand, normally do not achieve postulational and ontological consolidation, nor are they deductive explanations of the predecessor theories by their successors: reduction2. Involves a varied collection of intertheoretic relations rather than a single, distinctive logical or mathematical relation. P = m v / sqrt(1 v^2/c^2) Where m is rest mass, to the classical formula p = m v, in the limit as v -> 0.
