Kuhn and Feyerabend formulated the problem. Dilworth provides the
solution.
In this highly original and insightful book, Craig Dilworth answers all
the questions raised by the incommensurability thesis. Logical
empiricism cannot account for theory conflict. Popperianism cannot
account for how one theory is a progression beyond another. Dilworth's
Perspectivist conception of science does both.
While remaining within the bounds of classical philosophy of science,
Dilworth does away with the logicism of his competitors. On the
Perspectivist view theory conflict is not contradiction, and theory
superiority does not consist in deductive subsumption or set-theoretic
inclusion. Here the relation between theories is analogous to the
application of individual concepts, and the question of theory
superiority becomes one of relative applicability. In this way Dilworth
succeeds in providing a conception of science in which scientific
progress is based on both rational and empirical considerations.
