Teny Pinkard's discussion of explanation in science and history raises some issues important for social science generally, as well as for history. I would like to focus on his analysis of the relationship between explanation and understanding, with the aim of reopening an issue which his treatment appears to have closed. In doing so, I hope to encourage further analysis of the problem of how we ‘understand’. My own discussion of this issue will be brief, moving only a little beyond (...) Pinkard's. Primarily. I hope to show that ‘understanding’ is in fact a problem, and one that cannot merely be viewed as secondary to an analysis of ‘explanation’. (shrink)

The concept of metaphor as primarily a vehicle for conveying ideas, even if unusual ones, seems to me as wrong as the parent idea that a metaphor has a special meaning. I agree with the view that metaphors cannot be paraphrased, but I think this is not because metaphors say something too novel for literal expression but because there is nothing there to paraphrase. Paraphrase, whether possible or not, inappropriate to what is said: we try, in paraphrase, to say it (...) another way. But if I am right, a metaphor doesn't say anything beyond its literal meaning . This is not, of course, to deny that a metaphor has a point, nor that that point can be brought out by using further words. . . . My disagreement is with the explanation of how metaphor works its wonders. To anticipate: I depend on the distinction between what words mean and what they are used to do. I think metaphor belongs exclusively to the domain of use. It is something brought off by the imaginative employment of words and sentences and depends entirely on the ordinary meanings of those words and hence on the ordinary meanings of the sentences they comprise.

Recent reports of CRISPR/Cas9 genome editing in parasitic helminths open up new avenues for research on these dangerous pathogens. However, the complex morphology and life cycles inherent to these parasites present obstacles for the efficient application of CRISPR/Cas9‐targeted mutagenesis. This is especially true with the trematode flukes where only modest levels of gene mutation efficiency have been achieved. Current major challenges in the application of CRISPR/Cas9 for study of parasitic worms thus lie in enhancing gene mutation efficiency and overcoming issues (...) involved in host passage so that mutated parasites survive. Strategies developed for CRISPR/Cas9 studies on Caenorhabditis elegans, protozoa and mammalian cells, including novel delivery methods, the choice of selectable markers, and refining mutation precision represent novel tactics whereby these impediments can be overcome. Furthermore, employing CRISPR/Cas9‐mediated gene drive to interfere with vector transmission represents a novel approach for the control of parasitic worms that is worthy of further exploration.

This essay interprets Butler’s distinction between identity in the loose and popular sense and in the strict and philosophical sense. Suppose there are different standards for counting the same things. Then what are two distinct things counting strictly may be one and the same thing counting loosely. Within a given standard identity is one-one. But across standards it is many-one. An alternative interpretation using the parts-whole relation fails, because that relation should be understood as many-one identity. Another alternative making identity (...) relative to sort fails, because whole and parts can be of the same sort. (shrink)

Construing the instantiation of a universal by a particular in terms of my theory of aspects resolves the basic mystery of this "non-relational tie", and gives theoretical unity to the four characteristics of instantiation discerned by Armstrong. Taking aspects as distinct in a way akin to Scotus's formal distinction, I suggest that instantiation is the sharing of an aspect by a universal and a particular--a kind of partial identity. This approach allows me to address Plato's multiple location and One over (...) Many problems, Bradley's problem concerning the instantiation of relations, and the problem of change. (shrink)

How is it possible for David Hume to be both withering skeptic and constructive theorist? I recommend an answer like the Pyrrhonian answer to the question how it is possible to suspend all judgment yet engage in active daily life. Sextus Empiricus distinguishes two kinds of assent: one suspended across the board and one involved with daily living. The first is an act of will based on appreciation of reasons; the second is a causal effect of appearances. Hume makes the (...) same distinction, only he extends the sort of assent involved in daily life to theoretical matters as well. He is a skeptic both in finding no reason to grant the first sort of assent and in being subject to the second. (shrink)

Hume discusses the distinction of reason to explain how we distinguish things inseparable, and so identical, e.g., the color and figure of a white globe. He says we note the respect in which the globe is similar to a white cube and dissimilar to a black sphere, and the respect in which it is dissimilar to the first and similar to the second. Unfortunately, Hume takes these differing respects of resemblance to be identical with the white globe itself. Contradiction results, (...) undermining his theory of abstraction. The way out is apparently to admit an intrinsic complexity in even simple things. (shrink)

Ordinary usage gives a way to think of identity through time: the Pittsburgh of 1946 was the same city as the Pittsburgh of today is--namely Pittsburgh. Problem: The Pittsburgh of 1946 does not exist; Pittsburgh still does. How can they have been identical? I reject the temporal parts view on which they were not but we may speak as though they were. Rather I argue that claiming their identity is not contradictory. I interpret ‘the Pittsburgh of 1946’ as ‘Pittsburgh as (...) it was in 1946’ and suggest that the apparent contradiction results from an ambiguity in the scope of ‘as’. (shrink)

The generation of evidence is integral to the work of public health and health service providers. Traditionally, ethics has been addressed differently in research projects, compared with other forms of evidence generation, such as quality improvement, program evaluation, and surveillance, with review of non-research activities falling outside the purview of the research ethics board. However, the boundaries between research and these other evaluative activities are not distinct. Efforts to delineate a boundary – whether on grounds of primary purpose, temporality, underlying (...) legal authority, departure from usual practice, or direct benefits to participants – have been unsatisfactory.

One of the advantages of my account in the essay “Instantiation as Partial Identity” was capturing the contingency of instantiation—something David Armstrong gave up in his experiment with a similar view. What made the contingency possible for me was my own non-standard account of identity, complete with the apparatus of counts and aspects. The need remains to lift some obscurity from the account in order to display its virtues to greater advantage. To that end, I propose to respond to those (...) who have grappled with it in print. There are various criticisms by commentators: that it is rendered absurd by the transitivity of identity, that it makes instantiation necessary instead of contingent, that it is unclear what counts are, that aspects are simply tropes, that my view does not capture multiple location, that I make an unclear reference to a theory of composition as identity, that the account suffers from problems with polyadicity, and that it is not a realist account of universals after all. I give responses to these objections. (shrink)

Hume's Treatise arguments concerning space, time, and geometry, especially ones involving his denial of infinite divisibility; have suffered harsh criticism. I show that in the section "Of the ideas of space and time," Hume gives important characterizations of his skeptical approach, in some respects Pyrrhonian, that will be developed in the rest of the Treatise. When that approach is better understood, the force of Hume's arguments can be appreciated, and the influential criticisms of them can be seen to miss the (...) mark. (shrink)

Understanding Hume’s theory of space and time requires suspending our own. When theorizing, we think of space as one huge array of locations, which external objects might or might not occupy. Time adds another dimension to this vast array. For Hume, in contrast, space is extension in general, where being extended is having parts arranged one right next to the other like the pearls on a necklace. Time is duration in general, where having duration is having parts occurring one aft (...) er another like the notes of a song. Hume’s diff erent view stems from his empiricism, his reliance on experience and observation as the foundation of our concepts. Nothing in our experience suggests a single vast array of locations. Rather, we simply notice that bodies are similar insofar as they have lengths that can be compared. Likewise, nothing in our experience suggests a single dimension of time. Rather, we simply notice that diff erent successions are similar insofar as they have durations that can be compared. Th eorizing that these observations show there to be a single multidimensional array goes well beyond the evidence for Hume. As a skeptic, he fi nds himself unable to assent to theories that stray too far beyond the deliverances of the senses. For Hume, the ideas of space and time are each a general idea of simple—partless— objects arrayed in a certain manner. He argues that the structures of the ideas of space and time refl ect the structures of space and time. Th erefore, space and time are not infi - nitely divisible, and they are ways simple objects are arrayed. Consequently, there is no such thing as empty space nor time without change. (shrink)

A variation of Bell's theorem that deals with the indeterministic case is formulated and proved within the logical framework of Lewis's theory of counterfactuals. The no-faster-than-light-influence condition is expressed in terms of Lewis would counterfactual conditionals. Objections to this procedure raised by certain philosophers of science are examined and answered. The theorem shows that the incompatibility between the predictions of quantum theory and the idea of no faster-than-light influence cannot be ascribed to any auxiliary or tacit assumption of either determinism (...) or the related idea that outcomes of unperformed measurements are determinate within nature. In addition, the theorem provides an example of an application of Lewis's theory of counterfactuals in a rigorous scientific context. (shrink)

In _The Body in Late-Capitalist USA_, Donald M. Lowe explores the varied social practices that code and construct the body. Arguing that our bodily lives are shaped by a complex of daily and ongoing practices—how we work, what we buy and consume—Lowe contends that as a result of the commodification of these and other social practices in the late-twentieth century, what we often understand to be the needs of the body are in fact means for capital accumulation. Moving beyond (...) studies of representations and images of the body, Lowe focuses on the intersection of body practices, language, and the Social to describe concretely the reality of a lived body. His strongly synthetic work brings together Marxist critique, semiotics, Foucaultian discourse analysis, and systems and communications theory to examine those practices that construct the body under late capitalism: habits of work and consumption, the ways we give birth and raise children, socialization, mental and physical healing, reconstructions and contestations of sexuality and gender. Lowe draws upon a wide range of sources, including government and labor studies and statistics, diagnostic and statistical manuals on mental illness, computer manuals, self-help books, and guides to work-related stress disorders, to illustrate the transformation of the body into a nexus of exchange value in postmodern society.

This book provides a defence of epistemological relativism against its most powerful opponents.

The divide between oneself and others has made altruism seem irrational to some thinkers, as Sidgwick points out. I use characterizations of grief, especially by St. Augustine, to question the divide, and use a composition‐as‐identity metaphysics of parts and wholes to make literal sense of those characterizations.

In the Treatise Hume argues that the self is really many related perceptions, which we represent to ourselves as being one and the same thing. In the Appendix he finds this account inconsistent. Why? The problem arises from Hume's theory that representation requires resemblance. Only a many can represent a many recognized as such, and only a one can represent something as one. So for the many distinct perceptions (recognized as such) to be represented as one and the same, the (...) many distinct ideas that reflect them must be one and the same. But the distinct cannot be identical. (shrink)

An assertion of high conditional probability or, more briefly, an HCP assertion is a statement of the type: The conditional probability of B given A is close to one. The goal of this paper is to construct logics of HCP assertions whose conclusions are highly likely to be correct rather than certain to be correct. Such logics would allow useful conclusions to be drawn when the premises are not strong enough to allow conclusions to be reached with certainty. This goal (...) is achieved by taking Adams' (1966) logic, changing its intended application from conditionals to HCP assertions, and then weakening its criterion for entailment. According to the weakened entailment criterion, called the Criterion of Near Surety and which may be loosely interpreted as a Bayesian criterion, a conclusion is entailed if and only if nearly every model of the premises is a model of the conclusion. The resulting logic, called NSL, is nonmonotonic. Entailment in this logic, although not as strict as entailment in Adams' logic, is more strict than entailment in the propositional logic of material conditionals. Next, NSL was modified by requiring that each HCP assertion be scaled; this means that to each HCP assertion was associated a bound on the deviation from 1 of the conditional probability that is the subject of the assertion. Scaling of HCP assertions is useful for breaking entailment deadlocks. For example, it it is known that the conditional probabilities of C given A and of - C given B are both close to one but the bound on the former's deviation from 1 is much smaller than the latter's, then it may be concluded that in all likelihood the conditional probability of C given A ∧ B is close to one. The resulting logic, called NSL-S, is also nonmonotonic. Despite great differences in their definitions of entailment, entailment in NSL is equivalent to Lehmann and Magidor's rational closure and, disregarding minor differences concerning which premise sets are considered consistent, entailment in NSL-S is equivalent to entailment in Goldszmidt and Pearl's System-Z⁺. Bacchus, Grove, Halpern, and Koller proposed two methods of developing a predicate calculus based on the Criterion of Near Surety. In their randomstructures method, which assumed a prior distribution similar to that of NSL, it appears possible to define an entailment relation equivalent to that of NSL. In their random-worlds method, which assumed a prior distribution dramatically different from that of NSL, it is known that the entailment relation is different from that of NSL. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:323 A DEFENSE OF HUME ON IDENTITY THROUGH TIME A durable complaint against Hume is that he blatantly begs the question in his Treatise account of our acquisition of the idea of identity through time. Green and Grose made the accusation in 1878; one hundred years later Stroud echoed the same accusation, its force and liveliness seemingly undiminished. I suggest that this accusation is based on a tempting but (...) unwarranted assumption about Humean perceptions. It is unwarranted despite Price's arguments for it. When the assumption is corrected Hume is exonerated. This defense prepares the way for a new understanding of Hume's subtle and important theory of identity. Clarifying his theory is the goal; defending him is the means. I will merely summarize the Green and Grose interpretation, saving detailed examination for Stroud's. Stroud's version seems more tightly argued for and spares one the problems of interpreting commentators from a different philosophical tradition. Green and Grose run together Hume's account of the acquisition of the idea of identity, with his account of the application of that idea to a succession of related perceptions. This fully intended confusion can be explained by their understanding of Hume's claim that "impressions are... perishing existences." (T 194) They assume that for Hume no perception (impression or idea) is a unity if it exists at an interval of time composed of a succession of times. Rather the perception is really a succession of perceptions. Their assumed interpretation makes Hume seem to them to beg the question as follows: To acquire the idea of identity through time is to acquire the idea of something 324 which is unitary and exists at a succession of times. But any impression which might give this idea is really a succession of related impressions. A succession of related impressions can convey the idea of identity only by being confused with a unitary impression which exists at a succession of times. Such confusion would be possible only for someone who already had the idea of something unitary which exists at a succession of times. So the idea of 2 identity can be acquired only if it is already had. In other words, Hume claims that an impression had for a relatively long time gives the idea of identity. Any long impression is really a succession. A succession can give the idea of identity only if it is confused with something that has identity. That confusion requires the idea of identity already. So Hume begs the question. There are gaps in this argument. But its influence has been important and its structure is clear: If we assume that perceptions are exceedingly brief, then Hume begs the question. (I will call the assumption 'the prosecution's assumption.') Stroud's argument that Hume begs the question has the same structure, or so I will argue. The role of the prosecution's assumption is not immediately apparent, but it is a crucial role. Stroud's accusation is as follows: By Hume's definition, identity is the invariableness and uninterruptedness of an object through a supposed change in time. (T 201) However, on Hume's account of acquiring the concept of identity, the acquisition involves imagining a change in time without any variation or interruption in an object. But that just ¿s, by definition, to imagine the object's identity through the change in time. So acquiring the concept of identity requires an act of imagination involving the 325 concept of identity. So, Stroud concludes, on Hume's account the concept of identity can be acquired only 3 if it is had. Hume's account begs the question. I think it is usually unwise to attribute blunders to subtle thinkers. I will not do it to Hume, nor to his commentators. I will argue that what Hume presupposes in explaining identity through time is a little different from identity through time. Thus the presupposition is not question-begging. More specifically, I will argue that Hume distinguishes three technical concepts, three ways to take up time: (i) merely occupying an interval of time, (ii) having duration for an interval of time, and (iii) being identical through an interval of time. Concept (iii... (shrink)

Hume seems to argue unconvincingly against the infinite divisibility of finite regions of space. I show that his conclusion is entailed by respectable metaphysical principles which he held. One set of principles entails that there are partless (unextended) things. Another set entails that these cannot be ordered so that an infinite number of them compose a finite interval.

Hume argues that there are steadfast objects - objects not themselves successions at all, yet which co-exist with successions. Given Hume's account of moments as abstractions from temporal simples, there being steadfast objects entails there being single moments that co-exist with successions of moments. Thus time is more like a wall of variously sized bricks than like a line. I formalize the assumptions behind this surprising view, in order to make sense of it and in order to show that it (...) is consistent. I note also that this view justifies the common-sense assumptions that time flows and is unlike space. (shrink)

John Rawls has recently shifted to a "freestanding" or "political" liberalism from his earlier "comprehensive" and "moral" liberalism. I argue that this move is based on several key features that make Rawlsian liberal pluralism indelibly postmodern. Two of the more obvious features are the denial of foundationalism and the rejection of a truth status for public-sphere justifications of the basic political structure. In conclusion, I suggest that a late-modern postliberalism is a viable alternative.

Berkeley and Hume object to Locke's account of abstraction. Abstraction is separating in the mind what cannot be separated in reality. Their objection is that if a is inseparable in reality from b, then the idea of a is inseparable from the idea of b. The former inseparability is the reason for the latter. In most interpretations, however, commentators leave the former unexplained in explaining the latter. This article assumes that Berkeley and Hume present a unified front against Locke. Hume (...) supplements Berkeley's argument just where there are gaps. In particular, Hume makes explicit something Berkeley leaves implicit: The argument against Locke depends on the principle that things are inseparable if and only if they are identical. Abstraction is thinking of one of an inseparable pair while not thinking of the other. But doing so entails thinking of something while not thinking of it. This is the fundamental objection.

Armstrong has loose identity be an equivalence relation, yet in cases of something becoming something else, loose identity is not transitive. My alternate account has an attribution of loose identity be really two: a true attribution of an underlying relation (perhaps not transitive) and a false attribution--a Humean feigning-of strict identity. The feigning may become less appropriate as the underlying relation grows more distant. What makes it appropriate initially is that the underlying relation supports a predictable change in some collective. (...) The importance of the predictably changing collective is signaled by regarding it as a single thing. (shrink)

Berkeley says both that one sometimes immediately perceives the same thing by sight and touch, and that one never does. To solve the contradiction I recommend and explain a distinction Berkeley himself makes—between two uses of ‘same’. This solution unifies two seemingly inconsistent parts of Berkeley’s whole project: He argues both that what we see are bits of light and color organized into a language by which God speaks to us about tactile sensations, and yet that we directly see ordinary (...) objects. My solution explains how these can come to the same thing. (shrink)

Hume’s account of virtue (and beauty) entails that distinct things--a quality in the contemplated and a perception in the contemplator--are the same thing--a given virtue. I show this inconsistency is consistent with his intent. A virtue is a composite of quality and perception, and for Hume a composite is distinct things--the parts--falsely supposed to be a single thing. False or unsubstantiated supposition is for Hume the basis of most of our beliefs. I end with an argument that for Hume secondary (...) qualities are composites, not powers. (shrink)

This article discusses the Tang Wei incident, which evolved across the first half of 2008, during the run-up to the Olympic Games in Beijing. Tang Wei is a Chinese actress whose breakthrough role in Ang Lee’s film Lust, Caution caused a sensation amongst Chinese audiences. The nudity and sex scenes in the film were explicit, and as such challenged accepted norms in film content. This aspect of the film, combined with the characterization of a national traitor as a heroine, caused (...) deep concern among some parties involved in film regulation and censorship. The argument presented here is that Tang Wei, who was singled out for criticism and upon whom travel and work restraints were placed in the aftermath of the film’s release, was made a scapegoat for the disgust experienced by a masculinist political class when faced with female dissent and sexuality.

In a regressive tax system, lower-income taxpayers pay larger percentages of their incomes in taxes compared to higher-income taxpayers. Although most policymakers and citizens view regressive taxation as generally unfair and unethical, the U.S. tax system taxes wage, salary, and self-employment income in a manner that deliberately subjects lower-income taxpayers to marginal tax rates that are greater than those imposed on higher-income taxpayers. As a result, some lower-income taxpayers pay a larger percentage of their income in taxes than higher-income taxpayers. (...) In this essay, we argue that this regressiveness in the taxation of salaried income is unfair and unethical. We then evaluate President Obama’s social security plan, which would retain most of the current tax system’s regressive structure. Finally, we offer two simple alternative proposals that are non-regressive, and thus more fair and ethical approaches to the taxation of salaried income. (shrink)

There are two inspirations for the theory presented. One is the Kantian idea that a free choice affects a deterministic sequence of events globally rather than just locally. The second is the Leibnizian idea that God chooses for actuality the possible world he deems best. But instead of God choosing, suppose free agents collectively do. Let actuality be an office which deterministic possible worlds are voted in and not of. In this way free choice can change things even if every (...) event is fully governed by deterministic laws: free choice substitutes one deterministic world for another. One way to look at the actual world on this theory is as a patchwork of segments of possible worlds. This gives the theory two advantages over familiar compatibilisms: it explains how the future is unsettled until chosen, and it allows that free choices are spontaneous. (shrink)
