Empirical evidence shows that secrecy in science has increased over the past decades, partly as a result of the commercialization of science. There is a good prima facie case against secrecy in science. It is part of the traditional ethos of science that it is a collective and open truth-seeking endeavor. In this paper, I will investigate whether secrecy in science can ever be epistemically justified. To answer this question, I first distinguish between different sorts of secrecy. Next, I propose (...) an account of what it is for a practice to be epistemically justified, with the help of work by Alvin Goldman and Philip Kitcher. I then discuss motivations for secrecy in science that are found in the literature to see whether they amount to, or can be turned into, epistemic justifications for secrecy. The conclusion is that, although some forms of secrecy are epistemically justified, secrecy that arises from special, often commercial, interests is not. (shrink)

Starting from the sixties of the past century theory change has become a main concern of philosophy of science. Two of the best known formal accounts of theory change are the post-Popperian theories of verisimilitude (PPV for short) and the AGM theory of belief change (AGM for short). In this paper, we will investigate the conceptual relations between PPV and AGM and, in particular, we will ask whether the AGM rules for theory change are effective means for approaching the truth, (...) i.e., for achieving the cognitive aim of science pointed out by PPV. First, the key ideas of PPV and AGM and their application to a particular kind of propositional theories - the so called "conjunctive propositions" - will be illustrated. Afterwards, we will prove that, as far as conjunctive propositions are concerned, AGM belief change is an effective tool for approaching the truth. (shrink)

Janet Kourany argues that philosophers of science should place more emphasis on the moral and political aspects of scientific research. As a possible site for philosophical intervention she discusses professional codes of ethics. James Brown describes various systemic problems in pharmaceutical research and proposes that socializing medical research is the best way to remedy the situation. I criticize each of their examples, but concur with many overall aspects of their expanded agenda for philosophy of science. †To contact the author, please (...) write to: Department of History and Philosophy of Science, Indiana University, Bloomington, IN 47405; e‐mail: [email protected].
