What role have experiments played, and should they play, in physics? How does one come to believe rationally in experimental results? The Neglect of Experiment attempts to provide answers to both of these questions. Professor Franklin's approach combines the detailed study of four episodes in the history of twentieth century physics with an examination of some of the philosophical issues involved. The episodes are the discovery of parity nonconservation in the 1950s; the nondiscovery of parity nonconservation in the 1930s, when (...) the results of experiments indicated, at least in retrospect, the symmetry violation, but the significance of those results was not realized; the discovery and acceptance of CP symmetry; and Millikan's oil-drop experiment. Franklin examines the various roles that experiment plays, including its role in deciding between competing theories, confirming theories, and calling fo new theories. The author argues that one can provide a philosophical justification for these roles. He contends that if experiment plays such important roles, then one must have good reason to believe in experimental results. He then deals with deveral problems concerning such reslults, including the epistemology of experiment, how one comes to believe rationally in experimental results, the question of the influence of theoretical presuppositions on results, and the problem of scientific fruad. This original and important contribution to the study of the philosophy of experimental science is an outgrowth of many years of research. Franklin brings to this work more than a decade of experience as an experimental high-energy physicist, along with his significant contributions to the history and philosophy of science. (shrink)

You are clever, Thrasymachus, I said, for you know very well that if you asked anyone how much is twelve, and as you asked him you warned him: "Do not, my man, say that twelve is twice six, or three times four, or six times two, or four times three, for I will not accept such nonsense," it would be quite clear to you that no one can answer a question asked in those terms. (Republic 337b).

The missing piece of the puzzle: the discovery of the Higgs boson On July 4, 2012 the CMS and ATLAS collaborations at the large hadron collider jointly announced the discovery of a new elementary particle, which resembled the Higgs boson, the last remaining undiscovered piece of the standard model of elementary particles. Both groups claimed to have observed a five-standard-deviation effect above background, the gold standard for discovery in high-energy physics. In this essay I will briefly discuss the how the (...) CMS collaboration performed the experiment and analyzed the data. I will also show the experimental results. (shrink)

Female genital alteration is any cutting, removal or destruction of any part of the external female genitalia. Various FGA practices are common throughout the world. While most frequent in Africa and Asia, transglobal migration has brought ritual FGA to Western nations. All forms of FGA are generally considered undesirable for medical and ethical reasons when performed on minors. One ritual FGA procedure is the vulvar nick. This is a small laceration to the vulva that does not cause morphological changes. Besides (...) being performed as a primary ritual procedure it has been proposed as a substitute for more extensive forms of FGA. Measures advocated or taken to reduce the burden of FGA can be punitive or non-punitive. Even if it is unethical to perform VN, we argue that it also is unethical to attempt to suppress it through punishment. First, punishment of VN is likely to cause more harm than good overall, even to those ostensibly being protected. Second, punishment is likely to exceed legitimate retributive ends. We do not argue in favor of performing VN. Rather, we argue that non-punitive strategies such as education and harm reduction should be employed. (shrink)

This is the text of The Lindley Lecture for 2009, given by Allan Gibbard, an American philosopher.

In her study Anarchism and Education, Judith Suissa argues that anarchist learning entails a constant interplay of tensions arising from emergent desires to transform society and the challenges society poises for realizing them. This is inescapable because a critical attitude is integral to an anarchist process of learning, infusing it with creative license premised on the conviction that we need not accept things as they are, that learning is not only a space for understanding, but also enactment. My purpose is (...) to explore this dynamic in the work of graphic artist Kevin Pyle, an American-born artist with a substantive body of illustrated books and comics addressing a myriad of issues. I am interested... (shrink)

The justification for restrictive state intervention (RSI) such as criminal punishment or state reversal of parental decisions is called a limiting, or intervention (Buchanan and Brock 1989, 10), p...

In this paper I argue, using two case studies of episodes from recent physics against the contingency view advocated by social constructionists. In this view, physics, or science in general, is, in Ian Hacking’s words, not determined by anything. Much of the previous discussion has centered on examples of scientific success. In this paper I argue that experimental evidence and reasoned and critical discussion played the crucial role in the refutation of a previously strongly believed hypothesis, and in the decision (...) that a proposed new elementary particle did not exist, leaving no reasonable doubt. I suggest that the argument against contingency does not require the absence of all possible doubt, but rather the absence of reasonable doubt.Keywords: Contingency; Refutation; 17-keV neutrino; Parity nonconservation.

I consider an objection to Lewisian modal realism: the view entails that there are a great many real evils that we ought to care about, but in fact we shouldn’t care about these evils. I reply on behalf of the modal realist – we should and do care about possible evils, and this is shown in our reactions to fictions about evils, which (plausibly, for the modal realist) are understood as making certain possible evils salient.
