Modularity has become a central and remarkably useful concept in evolutionary developmental biology, offering an explanation of how independent, interacting units make possible developmental events and evolutionary changes. These modules exist at several different levels of organization, from genes to signal transduction pathways to cell populations. Cell populations, which are multicellular modules, provide an opportunity both to clarify our notion of modularity and to reexamine such central concepts as cell-to-cell communication. Rosine Chandebois’s work on “cell sociology” is reframed in the (...) language of modularity in order to show how groups of cells maintain their collective identity during development and how signaling information from the group’s environment is received by the constituent cells. In a “test case” for our account of multicellular modules, we consider the vertebrate neural crest, a migratory cell population made up of several subpopulations. The neural crest proves yet again to be a complex case, showing the importance of taking into account both developmental and evolutionary transformations of multicellular modules. (shrink)

We use the comparative method of language acquisition research to investigate children’s expression of directional expressions in two Eastern Mayan languages – K’iche’ and Mam. Both languages add clitics derived from verbs such as ‘go’ and ‘stay’ to their verb complex to express the direction an agent takes in the course of accomplishing an event. Historic changes to the prosodic structure of the verb complex in both languages explain why the directional clitics are predominately postverbal in K’iche’, while they occur (...) in preverbal and postverbal positions in Mam. Prosody explains why K’iche’ children initially produce clitics postverbally, while Mam children produce clitics both preverbally and postverbally. Prosody also explains why the children acquiring both languages produce morphemes in the verb complex that are relatively infrequent but prosodically prominent, while omitting obligatory morphemes that are prosodically weak.

The contribution of data use in schools has been proven via visible changes in policy and practice in schools, changes in practitioners learning or cognition and changes in opinions or attitudes regarding teaching or policy-making. Nevertheless, limited research is available on the extent to which data use in schools results in the aforementioned effects and how they can be explained by data use expectations and collaboration. This paper addresses both issues by describing and explaining data use effects via a large-scale (...) study in Flanders. Data collected from 1472 teachers indicate that, although teachers are moderately positive about the extent to which data use results in different types of effects, data use effects cannot be taken for granted. Structural Equation Modelling shows that explicating data use expectations and data use collaboration are essential in order to facilitate data use effects in schools. (shrink)

This paper propounds a new reading of Berkeley's account of the activity of finite spirits. Against existing interpretations, the paper argues that Berkeley does not hold that we causally contribute to the movement of our bodies. In contrast, our volitions to move our bodies are but occasions for God to cause their movement. In answer to the question of wherein then consists our activity, the paper proposes that our activity consists in the dual powers to produce (1) our volitions ? (...) the acts of willing ? and (2) our ideas of imagination. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Ideas 61.1 (2000) 19-37 [Access article in PDF] Eudaimonism and Theology in Stoic Accounts of Virtue Michael Gass The Stoics were unique among the major schools in the ancient world for maintaining that both virtue and happiness consist solely of "living in agreement with nature" (homologoumenos tei phusei zen). We know from a variety of texts that both Cleanthes and Chrysippus, if not (...) also Zeno, characterized such conduct both in essentialist terms, as a matter of living purposively in a manner natural for the human species, and in cosmological terms, as a matter of living in agreement with the purposes of nature as a whole, this being regarded as identical to Zeus. This is not to suggest, however, that cosmo-theological speculation figured prominently in the ethical systems of the early Stoics. Judging from extant summaries and discussions of Stoic ethical doctrines, those doctrines were justified in a dialectical fashion, not by appeal to facts about the purposive order of nature but simply from an analysis of ethical concepts patterned after similar analyses by earlier philosophers (most notably, Aristotle). It is this kind of learning that Chrysippus apparently had in mind when he maintained that ethics should be studied prior to undertaking a systematic investigation of nature: [T]here are three kinds of philosopher's theorems, logical, ethical and physical.... [W]hat should be ranked first of these are the logical, next the ethical, third the physical; and what should come last in the physical theorems is theology. 1On the other hand, as we learn from the testimony of Plutarch (and also from other indirect textual evidence examined recently by Jacques Brunschwig), 2 [End Page 19] Chrysippus also believed that physics in general and theology in particular yield a quite distinct, demonstrative knowledge of the matters first studied in ethics. A. A. Long and others have suggested that such knowledge was regarded by the Stoics as encompassing not just information about the ways in which virtuous living is encouraged by, and fits into, the wider aims of nature at large but also a deeper understanding of the very essence of virtue. 3 Specifically, virtue is revealed to consist in a conscious and deliberate harmonization of one's actions with the purposes of the divine architect. Thus, under this interpretation of their ethical intentions, the Stoics thought of the initial, analytical approach to ethics as necessarily incomplete even in its treatment of strictly ethical topics; the systematic study of nature was thought to impart additional wisdom regarding ethical matters.In her recent study of ancient ethical theories, Julia Annas seeks to counter this view of the place of cosmo-theological speculation in early Stoicism by arguing that such a religious characterization of virtue is incompatible with the eudaimonism to which all schools of ancient philosophy, including Stoicism, were committed. 4 She concedes that first Cleanthes and then much later the Roman Stoics did regard virtue in religious terms, but in her assessment this represents a radical departure from mainstream Stoic thinking on this subject (which is identified mostly with the views of Chrysippus and his disciples, all of whom were clearly and consistently committed to the eudaimonistic model of ethical inquiry). Annas argues that whereas the Stoic sage was traditionally depicted as a person whose commitment to morally appropriate conduct stems from his own rational reflection on his own needs and interests, a person who identified completely with the aims of the divine architect in his purposive activity would be someone who surrendered his right to decide for himself what his needs and interests are, and who therefore could even be required to act in violation of what he might judge by himself to be crucial to his happiness.In what follows I demonstrate that this argument, often advanced in the literature as a reductio ad absurdum of divine command theories of morality, falls wide of the mark in the present case due to the fact that those Stoics who characterized virtue in religious terms did so apparently because they regarded a complete identification with...

In this paper we argue that there are valuable consonances between democratic theory and music theory, and between democratization and musical performance and enjoyment. We suggest that this connection is not as trite as it may first appear, but that, since democracy is learned and practiced in a myriad ofways, music is one such place to learn democratic citizenship. The paper begins with a normative account of democratic theory that is present in two movements. The first, “foundations,” explicates the essential (...) components, criteria, and conditions of democracy. The second, “flows,” addresses the dynamism of democratization. Here is an account of what democracy looks like in action. We then turn to an explication of music theory and improvisation. Here, we focus on jazz as a way to hear the kind of interplay, responsiveness, accountability, discipline, and extemporaneousness that occurs in good jazz, and in authentic (radical) democracy.

We study thorn forking and rosiness in the context of continuous logic. We prove that the Urysohn sphere is rosy (with respect to finitary imaginaries), providing the first example of an essentially continuous unstable theory with a nice notion of independence. In the process, we show that a real rosy theory which has weak elimination of finitary imaginaries is rosy with respect to finitary imaginaries, a fact which is new even for discrete first-order real rosy theories.

We develop a basic theory of rosy groups and we study groups of small Uþ-rank satisfying NIP and having finitely satisfiable generics: Uþ-rank 1 implies that the group is abelian-by-finite, Uþ-rank 2 implies that the group is solvable-by-finite, Uþ-rank 2, and not being nilpotent-by-finite implies the existence of an interpretable algebraically closed field.

Is a human more conscious than an octopus? In the science of consciousness, it’s oftentimes assumed that some creatures (or mental states) are more conscious than others. But in recent years, a number of philosophers have argued that the notion of degrees of consciousness is conceptually confused. This paper (1) argues that the most prominent objections to degrees of consciousness are unsustainable, (2) examines the semantics of ‘more conscious than’ expressions, (3) develops an analysis of what it is for a (...) degreed property to count as degrees of consciousness, and (4) applies the analysis to various theories of consciousness. I argue that whether consciousness comes in degrees ultimately depends on which theory of consciousness turns out to be correct. But I also argue that most theories of consciousness entail that consciousness comes in degrees. (shrink)

Tao has been built into the foundation of East Asian culture for millennia, and many books have been written to explain it. But Tao cannot fully be explained in words; it can only felt and experienced. Tao is something you live, day by day, moment by moment. Its the omnipresent oneness beyond ephemeral phenomena that expresses itself in everything.

This article focuses on the relationship between evaluations of beauty and the ethics of living well. Separating these ideas typically involves understating how racism and patriarchy shape wider cultural and aesthetic sensibilities. I counter this tendency by foregrounding the precarity of vulnerable black children and the importance of self‐love in their efforts to flourish. My strategy involves placing Toni Morrison in conversation with Alexander Nehamas and Harry Frankfurt, philosophers who have carefully engaged the topics of beauty and love. By situating (...) aesthetic judgment within ongoing practices of social formation and political contestation, I reveal the importance of linking beauty with practices of self‐regard while also detailing my criticisms of thinkers who downplay their significance. The effect is to position Morrison as an instructive guide for scholars interested in aesthetics, ethics, and politics. (shrink)

Entanglement has long been the subject of discussion by philosophers of quantum theory, and has recently come to play an essential role for physicists in their development of quantum information theory. In this paper we show how the formalism of algebraic quantum field theory (AQFT) provides a rigorous framework within which to analyse entanglement in the context of a fully relativistic formulation of quantum theory. What emerges from the analysis are new practical and theoretical limitations on an experimenter's ability to (...) perform operations on a field in one spacetime region that can disentangle its state from the state of the field in other spacelike-separated regions. These limitations show just how deeply entrenched entanglement is in relativistic quantum field theory, and yield a fresh perspective on the ways in which the theory differs conceptually from both standard non-relativistic quantum theory and classical relativistic field theory.

This paper examines the idea of "objective phenomenology," or a way of understanding the phenomenal character of conscious experiences that doesn’t require one to have had the kinds of experiences under consideration. My central thesis is that structural facts about experience—facts that characterize purely how conscious experiences are structured—are objective phenomenal facts. I begin by precisifying the idea of objective phenomenology and diagnosing what makes any given phenomenal fact subjective. Then I defend the view that structural facts about experience are (...) objective. I also argue that structural facts about experience, despite being objective, nevertheless still give rise to an explanatory gap. (shrink)

We show that three fundamental information-theoretic constraints -- the impossibility of superluminal information transfer between two physical systems by performing measurements on one of them, the impossibility of broadcasting the information contained in an unknown physical state, and the impossibility of unconditionally secure bit commitment -- suffice to entail that the observables and state space of a physical theory are quantum-mechanical. We demonstrate the converse derivation in part, and consider the implications of alternative answers to a remaining open question about (...) nonlocality and bit commitment. (shrink)

Peter Lewis ([1997]) has recently argued that the wavefunction collapse theory of GRW (Ghirardi, Rimini and Weber [1986]) can only solve the problem of wavefunction tails at the expense of predicting that arithmetic does not apply to ordinary macroscopic objects. More specifically, Lewis argues that the GRW theory must violate the enumeration principle: that 'if marble 1 is in the box and marble 2 is in the box and so on through marble n, then all n marbles are in the (...) box' ([1997], p. 321). Ghirardi and Bassi ([1999]) have replied that it is meaningless to say that the enumeration principle is violated because the wavefunction Lewis uses to exhibit the violation cannot persist, according to the GRW theory, for more than a split second ([1999], p. 709). On the contrary, we argue that Lewis's argument survives Ghirardi and Bassi' s criticism unscathed. We then go on to show that, while the enumeration principle can fail in the GRW theory, the theory itself guarantees that the principle can never be empirically falsified, leaving the applicability of arithmetical reasoning to both micro- and macroscopic objects intact.

We define a notion of residue field domination for valued fields which generalizes stable domination in algebraically closed valued fields. We prove that a real closed valued field is dominated by the sorts internal to the residue field, over the value group, both in the pure field and in the geometric sorts. These results characterize forking and þ-forking in real closed valued fields (and also algebraically closed valued fields). We lay some groundwork for extending these results to a power-bounded T-convex (...) theory. (shrink)

David Lewis—famously—never tasted vegemite. Did he have any knowledge of what it's like to taste vegemite? Most say 'no'; I say 'yes'. I argue that knowledge of what it’s like varies along a spectrum from more exact to more approximate, and that phenomenal concepts vary along a spectrum in how precisely they characterize what it’s like to undergo their target experiences. This degreed picture contrasts with the standard all-or-nothing picture, where phenomenal concepts and phenomenal knowledge lack any such degreed structure. (...) I motivate the degreed picture by appeal to (1) limits in epistemic abilities such as recognition, imagination, and inference, and (2) the semantics of ‘knows what it’s like’ expressions. I argue that approximate phenomenal knowledge cannot be explained merely via determinable or vague phenomenal concepts. I develop a framework for systematizing approximate knowledge of phenomenal character. And I explain how my view challenges some standard assumptions about the acquisition conditions, requirements for mastery, and referential mechanisms of phenomenal concepts. (shrink)

Philosophical reflection on quantum field theory has tended to focus on how it revises our conception of what a particle is. However, there has been relatively little discussion of the threat to the "reality" of particles posed by the possibility of inequivalent quantizations of a classical field theory, i.e., inequivalent representations of the algebra of observables of the field in terms of operators on a Hilbert space. The threat is that each representation embodies its own distinctive conception of what a (...) particle is, and how a "particle" will respond to a suitably operated detector. Our main goal is to clarify the subtle relationship between inequivalent representations of a field theory and their associated particle concepts. We also have a particular interest in the Minkowski versus Rindler quantizations of a free Boson field, because they respectively entail two radically different descriptions of the particle content of the field in the *very same* region of spacetime. We shall defend the idea that these representations provide *complementary descriptions* of the same state of the field against the claim that they embody completely *incommensurable theories* of the field.

Totalitarianism is perhaps unanimously regarded as one of the greatest political evils of the last century and has been the grounds for much of Anglo-American political theory since. Confucianism, meanwhile, has been gaining credibility in the past decades among sympathizers of democratic theory in spite of criticisms of it being anti-democratic or authoritarian. I consider how certain key concepts in the classical Confucian texts of the Mencius and the Xunzi might or might not be appropriated for ‘legitimising’ totalitarian regimes. Under (...) an Arendtian approach to understanding totalitarianism, it is precisely an unproblematised relation to a normative History and Nature that underlies the potential compatibility or incompatibility. I argue against a longstanding prejudice that if any form of Confucianism would be totalitarian, it would have to be Xunzian. Against this, I hope to show that if any form of Confucianism would be totalitarian, it might well be a naturalistic Mencian Confucianism instead of a constructivist Xunzian one. (shrink)

Orthodox quantum mechanics includes the principle that an observable of a system possesses a well-defined value if and only if the presence of that value in the system is certain to be confirmed on measurement. Modal interpretations reject the controversial ‘only if’ half of this principle to secure definite outcomes for quantum measurements that leave the apparatus entangled with the object it has measured. However, using a result that turns on the construction of a Kochen–Specker contradiction, I argue that modal (...) interpretations cannot deliver a metaphysically tenable conception of properties in quantum mechanics unless they also abandon the less controversial ‘if’ half of the orthodox principle.

A survey of university students tested whether committing animal abuse during childhood was related to approval of interpersonal violence against children and women in families. Respondents who had abused an animal as children or adolescents were significantly more likely to support corporal punishment, even after controlling for frequency of childhood spanking, race, biblical literalism, and gender. Those who had perpetrated animal abuse were also more likely to approve of a husband slapping his wife. Engaging in childhood violence against less powerful (...) beings— animals—may generalize to the acceptance of violence against less powerful members of families and society—women and children. This paper discusses the implications of this process. (shrink)

I argue that experiences can have microphenomenal structures, where the macrophenomenal properties we introspect are realized by non-introspectible microphenomenal properties. After explaining what it means to ascribe a microstructure to experience, I defend the thesis against its principal philosophical challenge, discuss how the thesis interacts with other philosophical issues about experience, and consider our prospects for investigating the microphenomenal realm.

In his recent article On Relativity Theory and Openness of the Future (1991), Howard Stein proves not only that one can define an objective becoming relation in Minkowski spacetime, but that there is only one possible definition available if one accepts certain natural assumptions about what it is for becoming to occur and for it to be objective. Stein uses the definition supplied by his proof to refute an argument due to Rietdijk (1966, 1976), Putnam (1967) and Maxwell (1985, 1988) (...) that Minkowski spacetime leaves no room for objective becoming whatsoever. However, Stein's proof does not seem to go far enough. By considering only what events have become from the standpoint of any given event, Stein's uniqueness proof fails from the outset to allow for a more general kind of becoming whereby it is understood to occur from the standpoint of events on the particular worldlines followed by observers. This suggests that there may, after all, be more than one way to define objective becoming in Minkowski spacetime once each observer's worldline is allowed to figure in the definition. This suspicion is further aroused by two recent proposals for objective, worldline-dependent becoming due to Peacock (1992) and Muller (1992) who advocate ways of defining becoming that are not equivalent to the definition Stein's uniqueness proof delivers. Nevertheless, we show that Stein's uniqueness proofcan be extended in a natural way to cover this more general kind of becoming, provided one does not enrich standard Minkowski spacetime by privileging certain sets of worldlines over others in an unwarranted manner. Thus we aim to reinforce Stein's point that standard Minkowski spacetime does make room for objective becoming, but in essentially only one way, despite arguments and proposals to the contrary.

To address the rising concern that algorithmic decision-making may reinforce discriminatory biases, researchers have proposed many notions of fairness and corresponding mathematical formalizations. Each of these notions is often presented as a one-size-fits-all, absolute condition; however, in reality, the practical and ethical trade-offs are unavoidable and more complex. We introduce a new approach that considers fairness—not as a binary, absolute mathematical condition—but rather, as a relational notion in comparison to alternative decision-making processes. Using U.S. mortgage lending as an example use (...) case, we discuss the ethical foundations of each definition of fairness and demonstrate that our proposed methodology more closely captures the ethical trade-offs of the decision-maker.

The thesis of this paper is that because the significance of Western medicine lies in its ability to enhance the health of persons within a society, the practice of medicine is foremost an ethic and only thereafter a science. In support of the priority of an ethical perspective in medical practice, the paper explores the socio-cultural nature of knowledge, upon which science itself is constructed. Next, it draws from Levinas' philosophy, which illumines the problem of ontological and epistemological priority. Specifically, (...) it examines Levinas' rendering of the human face and of language, as they found the case for the priority of justice, or ethics. Finally, the paper offers the practice of narrative discourse as one solution that elevates the status of ethics within the institution of medicine and that has the potential to counteract the tendency in medical practice to employ a universalizing methodology based in science's power to control the human Other.
