The mechanistic approach in philosophy of science contributes to our understanding of experimental design. Applying the mechanistic approach to experimentation in computing is beneficial for two reasons. It connects the methodology of experimentation in computing with the methodology of experimentation in established sciences, thereby strengthening the scientific reputability of computing and the quality of experimental design therein. Furthermore, it pinpoints the idiosyncrasies of experimentation in computing: computing deals closely with both natural and engineered mechanisms. Better understanding of the idiosyncrasies, which (...) manifest in terms of a nonstandard role for experimentation, are interesting both for computer scientists and for philosophers of science. Computer scientists can think more clearly about their experimental choices. The role of experimentation elucidated by computer science merits further study from philosophers of science generally, as it highlights a role for experimentation hitherto unrecognized by philosophers: demonstration that activities exist.

Phyllis Illari and Jon Williamson propose a formulation for a general mechanistic account, the purpose of which is to capture the similarities across mechanistic accounts in the sciences. Illari and Williamson extract insight from mechanisms in astrophysics—which are notably different from the typical biological mechanisms discussed in the literature on mechanisms—to show how their general mechanistic account accommodates mechanisms across various sciences. We present argumentation that demonstrates why an amendment is necessary to the ontology referred to by the general mechanistic (...) account provided by Illari and Williamson. The amendment is required due to the variability of some components in computing mechanisms: the very same component serves as either entity or activity, both between levels and within the same level of the explanatory hierarchy. We argue that the proper ontological account of these mechanistic components involves disambiguation via explicitly indexing them as entities or activities. (shrink)

Contemporary scholars are engaged in a debate over whether Charles Augustin Coulomb’s results that he presented in his 1785 and 1787 memoirs to the Paris Academy of Sciences were attained experimentally or theoretically. In this paper, we study Coulomb’s famous 1785 electric torsion balance experiment through analysis of relevant texts and, more importantly, through a replication that is more faithful to Coulomb’s original design than previous attempts. We show that, despite recent claims, it has so far proved impossible to obtain (...) the same results reported by Coulomb in his paper of 1785, Coulomb’s published results are most likely atypical, and electric torsion balance experiments degenerate quickly when parameters are altered by small amounts. Acknowledgements: We wish to thank Jed Buchwald for generously making available the glass pieces of a torsion balance identical to that used by Alberto Martinez. Special thanks also to Paolo Palmieri for his important roles in replicating the electric torsion balance, discussing results and recording trials, as well as for the invaluable comments given on earlier drafts of this paper. A part of this paper was presented at the 2008 History of Science Society Annual Meeting in Pittsburgh, PA. We thank the participants of that meeting, especially Alberto A. Martinez, for helpful discussion and comments. Thank you also to Peter Heering for recent discussion and feedback. This research was supported by the Wesley C.

According to Eric Olson, the Thinking Animal Argument (TAA) is the best reason to accept animalism, the view that we are identical to animals. A novel criticism has been advanced against TAA, suggesting that it implicitly employs a dubious epistemological principle. I will argue that other epistemological principles can do the trick of saving the TAA, principles that appeal to recent issues regarding disagreement with peers and experts. I conclude with some remarks about the consequence of accepting these modified (...) principles, drawing out some general morals in defending animalism. (shrink)

Standard animalists are committed to a stringent form of restricted composition, thereby denying the existence of brains, hands, and other proper parts of an organism . One reason for positing this near-nihilistic ontology comes from various challenges to animalism such as the Thinking Parts Argument, the Unity Argument, and the Argument from the Problem of the Many. In this paper, I show that these putatively distinct arguments are all instances of a more general problem, which I call the ‘Too Many (...) Candidates Problem’ . Given my formulation of the problem, it is evident that standard animalists are mistaken in believing that restricting composition is the only solution. I show that there is another option for solving the TMC. The advantage of such a position, which I call ‘unrestricted animalism’, is that it is compatible with unrestricted composition and the existence of brains and other proper parts of an organism. I conclude by sketching several strategies one can take regarding this latter solution to the TMC. (shrink)

In trying to establish the view that there are no non-living macrophysical objects, Trenton Merricks has produced an influential argument—the Overdetermination Argument—against the causal efficacy of composite objects. A serious problem for the Overdetermination Argument is the ambiguity in the notion of overdetermination that is being employed, which is due to the fact that Merricks does not provide any theory of causation to support his claims. Once we adopt a plausible theory of causation, viz. interventionism, problems with the Overdetermination will (...) become evident. After laying out the Overdetermination Argument and examining one extant objection to it, I will explicate the relevant aspects of an interventionist theory of causation and provide a characterization of overdetermination that follows from such an account. From this, I will argue that the Causal Principle that undergirds the Overdetermination Argument is false and hence the argument is invalid; and I claim that the only other available characterization of overdetermination would render a key premise in the argument false. Thus, the Overdetermination Argument fails to provide us with any reason to deny the causal efficacy of macrophysical objects, and therefore provides no reason to doubt their existence. (shrink)

In some cases where we are faced with a decision of whether to prioritize identified lives over statistical lives, we have no basis for assigning specific probabilities to possible outcomes. Is there any reason to prioritize either statistical or identified lives in such cases? The ‘uncertainty argument’ purports to show that, provided we embrace ex ante contractualism, we should prioritize saving identified lives in such cases. The argument faces two serious problems. First, it relies on the principle of indifference, and (...) as such it leads to inconsistent assignments of epistemic probability to possible outcomes. Moreover, even if the uncertainty argument can be reformulated in order to avoid reliance on the principle of indifference, the uncertainty in such cases still undermines any judgment of which course of action – saving a statistical, or rather an identified life – involves the greater burden. The indeterminacy involved in the statistical group might be thought to undermine the argument that application of the principle of indifference leads to inconsistency in this case, but the thought that it does rests on a misunderstanding of the relationship between indeterminacy and reference.

In this paper we study changes of beliefs in a ranking-theoretic setting using non-extremal implausibility thresholds for belief. We represent implausibilities as ranks and introduce natural rank changes subject to a minimal change criterion. We show that many of the traditional AGM postulates for revision and contraction are preserved, except for the postulate of Preservation which is invalid. The diagnosis for belief contraction is similar, but not exactly the same. We demonstrate that the one-shot versions of both revision and contraction (...) can be represented as revisions based on semiorders, but in two subtly different ways. We provide sets of postulates that are sound and complete in the sense that they allow us to prove representation theorems. We show that, and explain why, the classical duality between revision and contraction, as exhibited by the Levi and Harper identities, is partly broken by threshold-based belief changes. We also study the logic of iterated threshold-based revision and contraction. The traditional Darwiche-Pearl postulates for iterated revision continue to hold, as well as two additional postulates that characterize ranking-based revision as a restricted `improvement' operator. We investigate the dual notion of iterated threshold-based belief contraction and provide a new set of postulates for it, characterizing contraction as a restricted 'degrading' operator. (shrink)

The Visitor’s inquiry into the expertise of statesmanship in Plato’s Statesman consistently privileges knowledge as the sole source from which to derive legitimate authority to command. And yet the section of the dialogue to which he refers as a “play” (δρᾶμα, 303c8) of satyrs and centaurs (291a–303d) complicates matters significantly by spelling out the difficulty of identifying a true statesman and the dangers of thinking ourselves able to do so. Reading the account of human community provided in the myth of (...) the cosmos together with the “good imitation” of knowledge in the satyr play, a limited notion of properly human wisdom comes into view as the horizon within which to interpret knowledge and dialectical division in the dialogue. I conclude that the education of the dialectician is connected to the problem of the absence of the true statesman, and that the Statesman is prescribing ways in which members of the philosophical community ought to understand themselves in dialogue with the written word.

Constituent ontologies maintain that the properties of an object are either parts or something very much like parts of that object. Recently, such a view has been criticized as leading to a bizarre and problematic form of substance dualism and implying the existence of impossible objects. After briefly presenting constituent and relational ontologies, I respond to both objections, arguing that constituent ontology does not yield either of these two consequences and so is not shown to be an unacceptable ontological framework.

International borders concentrate opportunities in some societies while limiting them in others. Borders also prevent those in the less favored societies from gaining access to opportunities available in the more favored ones. Both distributive effects of borders are treated here within a comprehensive framework. I argue that each state should have broad discretion under international law to grant or deny entry to immigration seekers; but more favored countries that find themselves under immigration pressure should be legally obligated to fund development (...) assistance for countries that generate immigration pressure. Funding should be subject to conditions of fair and effective use in recipient countries, and should aim at a near-term target of immigration-pressure equilibrium. Equilibrium obtains between two countries when, given appropriate background circumstances, the same proportion of individuals in each manifests a preference to migrate to the other. If meeting the equilibrium target in the short term would be to the long-term disadvantage of the worst-off countries, then a Pareto-superior alternative target supersedes. It mandates development assistance at the level that yields the most favorable human development projections for the worstoff countries. An implementable set of institutions is described that can achieve the equilibrium goal in the long term without unduly sacrificing other important ends, including economic growth, political stability, cultural integrity, the political autonomy of distinct societies, and their proper accountability for policy choices. Key Words: global justice • immigration • borders • development • distributive justice • development assistance • equality • international law • cosmopolitanism. (shrink)

We show in this paper that some expressions indicating source of evidence are part of propositional content and are best analyzed as special kind of epistemic modal. Our evidence comes from the Japanese evidential system. We consider six evidentials in Japanese, showing that they can be embedded in conditionals and under modals and that their properties with respect to modal subordination are similar to those of ordinary modals. We show that these facts are difficult for existing theories of evidentials, which (...) assign evidentials necessarily widest scope, to explain. We then provide an analysis using a logical system designed to account for evidential reasoning; this logic is the first developed system of probabilistic dynamic predicate logic. This analysis is shown to account for the data we provide that is problematic for other theories. (shrink)

Philip Kitcher has proposed a theory of explanation based on the notion of unification. Despite the genuine interest and power of the theory, I argue here that the theory suffers from a fatal deficiency: It is intrinsically unable to account for the asymmetric structure of explanation, and thus ultimately falls prey to a problem similar to the one which beset Hempel's D-N model. I conclude that Kitcher is wrong to claim that one can settle the issue of an argument's explanatory (...) force merely on the basis of considerations about the unifying power of the argument pattern the argument instantiates.

Children and individuals with developmental disabilities compared to typical participants are disadvantaged not only by virtue of being vulnerable to risks inherent in research participation but also by the higher likelihood of exclusion from research altogether. Current regulatory and ethical guidelines although necessary for their protection do not sufficiently ensure fair distributive justice. Yet, in view of disproportionately higher burdens of co-occurring physical and mental disorders in individuals with DD, they are better positioned to benefit from research by equitable participation. (...) Greater elucidation of this ethical dilemma is called for by researchers, institutional review boards, and funding agencies to urgently redress the imbalance. This article discusses many of the regulatory principles to ensure better research participation of children and individuals with DD: human rights, validity, distributive justice, beneficence/nonmaleficence, and autonomy.

Violations of the Bell inequalities in EPR-Bohm type experiments have set the literature on the metaphysics of microscopic systems to flirting with some sort of metaphysical holism regarding spatially separated, entangled systems. The rationale for this behavior comes in two parts. The first part relies on the proof, due to Jon Jarrett [2] that the experimentally observed violations of the Bell inequalities entail violations of the conjunction of two probabilistic constraints. Jarrett called these two constraints locality and completeness. We prefer (...) the terminology of locality and factorizability.[3] The first part of the rationale for metaphysical holism urges that only Jarrett’s locality allows for “peaceful coexistence” between any model of EPR-Bohm type experiments and special relativity. Factorizability, it is suggested, must be jettisoned. (shrink)

According to the popular-choice theory of secession, the inhabitants of any territory, as a group, should have an internationally recognized right to secede from a sovereign state if their majority chooses by referendum to do so, and if they are capable of sustaining legitimate state institutions. Prior efforts to defend this group right on individualistic grounds—such as the individual right to associate freely or to participate as an equal in democratic decision-making—have failed. As a result, some recent defenders of the (...) choice theory have suggested that the group right the theory implies is “irreducibly collective.” I argue, to the contrary, that this group right can be grounded fully in the fundamental right of each individual to be treated as an equal by the political institutions to which he is subject. The territorial implications of the choice theory are, moreover, consistent with a plausible account of the territorial rights of states. (shrink)

In this response I take issue with Professor Ausland’s use of the account of the soul in Republic 4 as a basis for reading Republic 8-9. I believe that the method and assumptions of Republic 4 are pre-dialectical and that Books 8-9 should be read in light of the digressive Books 5-7. By placing greater emphasis on the asymmetry between Book 4 and Books 8-9, the basic assumptions governing the decline of regimes will show themselves to tell a different story (...) of moral experience and moral decomposition than we find in Professor Ausland’s instructive and insightful reading of the dialogue.

The Homeric epics are among the greatest masterpieces of literature, but when they were produced is not known with certainty. Here we apply evolutionary-linguistic phylogenetic statistical methods to differences in Homeric, Modern Greek and ancient Hittite vocabulary items to estimate a date of approximately 710–760 BCE for these great works. Our analysis compared a common set of vocabulary items among the three pairs of languages, recording for each item whether the words in the two languages were cognate – derived from (...) a shared ancestral word – or not. We then used a likelihood-based Markov chain Monte Carlo procedure to estimate the most probable times in years separating these languages given the percentage of words they shared, combined with knowledge of the rates at which different words change. Our date for the epics is in close agreement with historians' and classicists' beliefs derived from historical and archaeological sources. (shrink)

The historical development of the electronic configuration model is traced and the status of the model with respect to quantum mechanics is examined. The successes and problems raised by the model are explored, particularly in chemical ab initio calculations. The relevance of these issues to whether chemistry has been reduced to quantum mechanics is discussed, as are some general notions on reduction.

Though whistleblowing is quickly becoming an accepted means of addressing wrongdoing, whistleblower protection laws and the relevant case law are either awkwardly silent, unclear or mutually inconsistent concerning public disclosures of classified government information. I remedy this problem by first arguing that such disclosures constitute a pro tanto wrong as they violate (1) promissory obligations, (2) role obligations and (3) the obligation to respect the democratic allocation of power. However, they may be justified if (1) the information disclosed concerns grave (...) government wrongdoing, (2) alternative channels of disclosure are first exhausted and (3) steps are taken to minimize harm.

Woodward's long awaited book is an attempt to construct a comprehensive account of causation explanation that applies to a wide variety of causal and explanatory claims in different areas of science and everyday life. The book engages some of the relevant literature from other disciplines, as Woodward weaves together examples, counterexamples, criticisms, defences, objections, and replies into a convincing defence of the core of his theory, which is that we can analyse causation by appeal to the notion of manipulation.

Debate has been growing in developmental psychology over how much the cognitive development of children is like theory change in science. Useful debate on this topic requires a clear understanding of what it would be for a child to have a theory. I argue that existing accounts of theories within philosophy of science and developmental psychology either are less precise than is ideal for the task or cannot capture everyday theorizing of the sort that children, if they theorize, must do. (...) I then propose an account of theories that ties theories and explanation very closely together, treating theories primarily as products of a drive to explain. I clarify some of the positions people have taken regarding the "theory theory" of development, and I concl.ude by proposing that psychologists interested in the 'theory theory' look for patterns of affect and arousal in development that would accompany the existence of a drive to explain.

This paper addresses the alleged tension between the kind of strong apophaticism endorsed by Maimonides and his view of worshiping God. After considering some extant resolutions to this problem, I offer a proposal that utilizes the role of silence and imitative activity in Maimonides. While this solution may not have been one that Maimonides would have offered, I argue that Maimonides had conceptual resources for offering a promising solution within his theological framework.

The miracle argument for scientific realism can be cast in two forms: according to the miraculous theory argument, realism is the only position which does not make the empirical successes of particular theories miraculous. According to the miraculous choice argument, realism is the only position which does not render the fact that empirically successful theories have been chosen a miracle. A vast literature discusses the miraculous theory argument, but the miraculous choice argument has been unjustifiably neglected. I raise two objections (...) to Richard Boyd's defense of the latter: (1) we have no miracle free account of the emergence of take-off theories and (2) the anti-realist can account for the non-miraculous choice of empirically successful theories by attributing mere empirical adequacy to background theory. I argue that the availability of extra-empirical criteria that are arguably truth conductive but not theory-laden suffices to answer (1), and the unavailability of extra-empirical criteria that are conductive to empirical adequacy but not necessarily to truth (and are also not theory-laden) constitutes to reply to (2). The prospects for a realist victory are at least somewhat promising, on a controversial assumption about the rate at which empirically successful theories emerge. (shrink)

It seems that we can know moral truths. We are also rather reluctant to defer to moral testimony. But it’s not obvious how moral cognitivism is compatible with pessimism about moral testimony. If moral truths are knowable, shouldn’t it be possible for others to know moral truths you don’t know, so that it is wise for you to defer to what they say? Or, alternatively, if it’s always reasonable to refuse to defer to the wisest among us, doesn’t this show (...) that morality is not genuinely cognitive? There is a tension in our commonsense moral epistemology. In this chapter I (a) explicate this tension, (b) criticize how others have attempted to resolve it, and finally (c) explain how Rossian deontology helps us see that the tension is only apparent: morality is indeed knowable, despite the fact that it is usually wise to refuse to defer to moral testimony.

A novel argument has recently been advanced against materialism—the view that human persons are identical to composite, material objects. The argument claims that pairs of people are not conscious and that the only viable explanation for why they are not is because pairs of people are not simple. The argument concludes that only a simple thing can be the subject of conscious states. In this paper, I offer an alternative explanation for why pairs of people are not conscious: pairs of (...) people are not substances. I provide two characterizations of substantiality. The first proposal claims that substances have irreducible causal powers, and the second claims that substances cannot have other substances as proper parts. The alternative explanation based on these characterizations of substantiality shows that being conscious is compatible with materialism. (shrink)

With a few exceptions, much of epistemology in the last century has been dominated by discussions centered on knowledge, and in particular propositional knowledge (along with associated concepts such as justification, the reliability of cognitive processes, etc.). Recently, attention has been given to other cognitive states such as understanding and wisdom, due in some part to the resurgence of theorizing about intellectual virtues. As with typical epistemic concepts such as justification and knowledge, offering an analysis of wisdom has been difficult. (...) In this paper, I critique a recent attempt to analyze wisdom as risk-taking, and after gleaning from the insights of Thomas Aquinas, I defend a particular version of the wisdom-as-understanding approach.

Some compatibilists have responded to the manipulation argument for incompatibilism by proposing an historical theory of moral responsibility which, according to one version, requires that agents be morally responsible for having their pro-attitudes if they are to be morally responsible for acting on them. This proposal, however, leads obviously to an infinite regress problem. I consider a proposal by Haji and Cuypers that addresses this problem and argue that it is unsatisfactory. I then go on to propose a new solution (...) inspired by the libertarian theory of Robert Kane. (shrink)

Isabelle Stengers anchors the major stake in Whiteheadian philosophy in the notion of constructivism. In doing so, the relation of this philosophy of becoming — the first anti-substantialist principle of which is stated as `principle of process' — to the ideas of vitalist intuition as the self-expression of the world is announced as eminently problematic. This problematizing opening to Whitehead obliges us to think about the constructivist nature of his concepts because of their irreducibility to the expression of facts of (...) experience since they must necessarily function as a machinic articulation of how things become implied in the `ontological principle' of reason; by the same token, it poses at the heart of the analysis the question of the pragmatic-speculative alterity in Whiteheadian constructivism.

Some recent work in mathematical chemistry is discussed. It is claimed that quantum mechanics does not provide a conclusive means of classifying certain elements like hydrogen and helium into their appropriate groups. An alternative approach using atomic number triads is proposed and the validity of this approach is defended in the light of some predictions made via an information theoretic approach that suggests a connection between nuclear structure and electronic structure of atoms.

Recently, philosophers have employed the notion of advice to tackle a variety of philosophical problems. In particular, Michael Smith and Nomy Arpaly have in different ways related the notion of advice to the notion of a reason for action. Here I argue that both accounts are flawed, because each operates with a simplistic picture of the way advice works. I conclude that it would be wise to take more time to analyze what advice is and how it in fact works, (...) before putting it to particular philosophical uses. (shrink)
