I. Epistemological relativism in its latest form

Gerald Doppelt's recent ‘Kuhn's Epistemological Relativism: An Interpretation and Defense’ (Inquiry, Vol. 21 1978], pp. 33–86) offers a reconstruction of Thomas Kuhn's views concerning theory choice in science in which Kuhn's ‘incommensurability thesis’, and his epistemological relativism, are defended. It is argued that Doppelt's reconstruction fails to provide an adequate defense, and that both Kuhn's incommensurability thesis, and his epistemological relativism, as reconstructed by Doppelt, remain philosophically unacceptable.
