The central questions of this study concern what qualifies as science, the reliability of scientific theories, and the ultimate purpose of science. The third topic is the normative evaluation of economic policies and outcomes. Chemists can use a number of indirect measures as evidence to rule out certain mechanisms, but they are often unsure if the remaining mechanism is correct because there are many other possible mechanisms that they have not tested or even thought of. By addressing foundations, adequacy, and new conceptual designs of scientific content, theories, and methods as well as of the theories about science, we aim also to clarify and establish the status of philosophy of science and other metascientific disciplines in this new scientific era. The December issue contains the PSA conference Proceedings. For Kuhn, acceptance or rejection of a paradigm is a social process as much as a logical process. radical theory change are clariﬁed and clearly explained for those new to the subject. What does it mean to prove a mathematical theorem and how does one know whether a mathematical proof is correct?
