This paper gives two complete and elementary proofs that if the speed of light over closed paths has a universal value c, then it is possible to synchronize clocks in such a way that the one-way speed of light is c. The first proof is an elementary version of a recent proof. The second provides high precision experimental evidence that it is possible to synchronize clocks in such a way that the one-way speed of light has a universal value. We (...) also discuss an old incomplete proof by Weyl which is important from an historical perspective. (shrink)

Universal Basic Income (UBI) can serve as a beneficial public policy to reduce poverty and inequality, yet a great challenge is how to fund it. This article offers a roadmap for fully funding UBI in a manner that: eliminates poverty; bolsters the middle-class; eliminates the stigma and government bureaucracy of social welfare programs; reduces ever-expanding inequality; initiates a path to meeting climate change goals; reduces speculation; and increases fairness and opportunity in the tax code. As stand-alone policies, these revenue proposals (...) are valuable correctives in their own right. If the entire package of UBI and funding sources were in effect, society (and American capitalism) would be on a more stable, equitable, and environmentally sustainable footing. (shrink)

Suppose that we have a method which estimates the conditional probabilities of some unknown stochastic source and we use it to guess which of the outcomes will happen. We want to make a correct guess as often as it is possible. What estimators are good for this? In this work, we consider estimators given by a familiar notion of universal coding for stationary ergodic measures, while working in the framework of algorithmic randomness, i.e., we are particularly interested in prediction of (...) Martin-Löf random points. We outline the general theory and exhibit some counterexamples. Completing a result of Ryabko from 2009 we also show that universal probability measure in the sense of universal coding induces a universal predictor in the prequential sense. Surprisingly, this implication holds true provided the universal measure does not ascribe too low conditional probabilities to individual symbols. As an example, we show that the Prediction by Partial Matching measure satisfies this requirement with a large reserve. (shrink)

Efforts to encourage universal access to information and communication technologies have run into the problem that some individuals, for reasons of affordability, lack of awareness or preference, continue to be without subscriptions. This article examines the arguments commonly put forward in support of promoting broadband access, to determine whether they can justify universalizing access. It examines the ethical limits of government actions that encourage, enforce or coerce participation in socially beneficial programmes, while potentially overlooking consumer sovereignty and human autonomy. The (...) conclusions address how policymakers can encourage universal access to broadband, while respecting the rights of citizens. (shrink)

Comparative constructions form two classes, those that permit direct comparisons (comparisons of measurements as in Seymour is taller than he is wide) and those that only allow indirect comparisons (comparisons of relative positions on separate scales as in Esme is more beautiful than Einstein is intelligent). In contrast with other semantic theories, this paper proposes that the interpretation of the comparative morpheme remains the same whether it appears in sentences that compare individuals directly or indirectly. To develop a unified account, (...) I suggest that all comparisons (whether in terms of height, intelligence or beauty) involve a scale of universal degrees that are isomorphic to the rational (fractional) numbers between 0 and 1. Crucial to a unified treatment, the connection between the individuals being compared and universal degrees involves two steps. First individuals are mapped to a value on a primary scale that ranks individuals with respect to the gradable property (whether it be height, beauty or intelligence). Second, the value on the primary scale is mapped to a universal degree that encodes the value’s relative position on the primary scale. Direct comparison results if measurements such as seven feet participate in the primary scale (as in Seven feet is tall). Otherwise the result is an indirect comparison. (shrink)

In this work we show that every structure [MATHEMATICAL SCRIPT CAPITAL A] can be expanded to a partial structure [MATHEMATICAL SCRIPT CAPITAL A]* with universal functions for the class of polynomials on [MATHEMATICAL SCRIPT CAPITAL A]*. We can embed [MATHEMATICAL SCRIPT CAPITAL A]* monomorphically in a total structure [MATHEMATICAL SCRIPT CAPITAL A]º that preserves universal functions of [MATHEMATICAL SCRIPT CAPITAL A]* and that is universal among such structures, i.e. [MATHEMATICAL SCRIPT CAPITAL A]º can be homomorphically embedded in every total structure (...) that preserves universal functions of [MATHEMATICAL SCRIPT CAPITAL A]*. Universal functions are the starting point for developing recursion theoretic tools in an [MATHEMATICAL SCRIPT CAPITAL A]* that satisfies some simple additional conditions. (shrink)

The remarkable successes of the physical sciences have been built on highly general quantitative laws, which serve as the basis for understanding an enormous variety of specific physical systems. How far is it possible to construct universal principles in the cognitive sciences, in terms of which specific aspects of perception, memory, or decision making might be modelled? Following Shepard (e.g., ), it is argued that some universal principles may be attainable in cognitive science. Here, 2 examples are proposed: the simplicity (...) principle (which states that the cognitive system prefers patterns that provide simpler explanations of available data); and the scale‐invariance principle, which states that many cognitive phenomena are independent of the scale of relevant underlying physical variables, such as time, space, luminance, or sound pressure. This article illustrates how principles may be combined to explain specific cognitive processes by using these principles to derive SIMPLE, a formal model of memory for serial order (), and briefly mentions some extensions to models of identification and categorization. This article also considers the scope and limitations of universal laws in cognitive science. (shrink)

Kant's Formula of Universal Law is shown to be an inadequate condition for morality because it uses the wrong scope for a universal qualifier, ranging only over the behavior of a set of agents in a world. If it instead ranges over the behavior of all possible agents, then we arrive at the stronger condition that a maxim is morally acceptable just if we can will, not just that all agents follow it simultaneously, but that any agent in any situation (...) may follow it--including, notably, in situations where some other agents are not following it. This stronger formulation avoids some of the counter-examples which Kant's formula is subject to. -/- Author's later note: the argument of this article is improved upon and essentially superseded by his later works on this topic (2012, 2013).

The universal generalization problem is the question: What entitles one to conclude that a property established for an individual object holds for any individual object in the domain? This amounts to the question: Why is the rule of universal generalization justified? In the modern and contemporary age Descartes, Locke, Berkeley, Hume, Kant, Mill, Gentzen gave alternative solutions of the universal generalization problem. In this paper I consider Locke’s, Berkeley’s and Gentzen’s solutions and argue that they are problematic. Then I consider (...) an alternative formulation of universal generalization which depends on the view that mathematical objects are individual objects and are hypotheses introduced to solve mathematical problems, and that mathematical proofs are argument schemata. I argue that this alternative formulation allows one to overcome the problems of Locke’s, Berkeley’s and Gentzen’s solutions, and is related to the approach to generality in Greek mathematics. I also argue that there is a connection between the present formulation of universal generalization and a special form of the analogy rule which is implicit in Proclus’ approach to the universal generalization problem.

Although the search for universal human traits is necessarily the principle focus of researchers in evolutionary psychology, the habitual reliance on undergraduate students introduces profound doubts concerning resulting data. Furthermore, the absence of relevant data from foraging societies undermines claims of cross-cultural universality in this paper and in many others.

This essay explores the possibility of universal values. Universal values do not exist as Platonic ideals nor do they exist in clearly defined lists of rules or laws. Rather, universal ethical claims are constructed through the actions of individual political leaders, scholars, and activists. This essay explores how such normative constructions take place. It uses an initiative undertaken by the UN Office of Drugs and Crime to further education around corruption as an example of how such universal values come into (...) existence. The initiative focused on developing teaching materials for higher education. The essay focuses on two particular modules, both their content and the process by which they were written. (shrink)

Spatial relations are central to geometrical thinking. With respect to the classical elementary geometry of Euclid’s Elements, a distinction between co-exact, or qualitative, and exact, or metric, spatial relations has recently been advanced as fundamental. We tested the universality of intuitions of these relations in a group of Senegalese and Dutch participants. Participants performed an odd-one-out task with stimuli that in all but one case display a particular spatial relation between geometric objects. As the exact/co-exact distinction is closely related to (...) Kosslyn’s categorical/coordinate distinction, a set of stimuli for testing all four types was used. Results suggest that intuitions of all spatial relations tested are universal. Yet, culture has an important effect on performance: Dutch participants outperformed Senegalese participants and stimulus layouts affect the categorical and coordinate processing in different ways for the two groups. Differences in level of education within the Senegalese participants did not affect performance. (shrink)

The rule of universal instantiation appears to be subject to counterexamples, although the rule of existential generalization is not subject to the same doubts. This paper is a survey of ways of responding to this problem, both conservative and revisionist. The conclusion drawn is that logical validity should be defined in terms of assertibility in a context rather than in terms of truth on an interpretation. Contexts are here defined, not in terms of the attitudes of the interlocutors, but in (...) terms of the goals of conversation, and assertibility is explained in terms of cooperation. (shrink)

In this paper we characterize, classify and axiomatize all universal classes of MV-chains. Moreover, we accomplish analogous characterization, classification and axiomatization for congruence distributive quasivarieties of MV-algebras. Finally, we apply those results to study some finitary extensions of the Łukasiewicz infinite valued propositional calculus.

We axiomatize all quantifier properties which can be expressed by a universal condition on the class of algebras of sets.

The aim of this study is to discuss in what sense one can speak about universal character of logic. The authors argue that the role of logic stands mainly in the generality of its language and its unrestricted applications to any field of knowledge and normal human life. The authors try to precise that universality of logic tends in: (a) general character of inference rules and the possibility of using those rules as a tool of justification of theorems of every (...) science, (b) principles of correct formulating of thoughts and using language, and (c) general deductive method of reasoning, i.e in the study of language syntax and semantics. The authors present two theories of language syntax and semantics as exemplifications based on the Tarski’s famous results in metalogic: (1) a formalization of universal syntax system by Andrzej Grzegorczyk based on a new primitive notion of quotation-marks operator, and (2) an enlarged system of axiomatic theory of syntax of any categorial language of Urszula Wybraniec-Skardowska’s in which the main role plays the relation of concatenation understood as a set-theoretical function. The study concludes in arguing that the importance of the result (2) lies not only in solving some philosophical problems but also in different fields of knowledge and spheres of human life as ex. in discussion and education as well.

Daoism has often been misunderstood as moral nihilism or anti-moralism, but the true Daoism indeed adopts a positive attitude towards morality. At the foundation of its universal sentiment is an affirmation of morality. Daoism takes all things as the starting point of its values in moral philosophy, and ziran 自然 (sponstaneously so) as the foundation of its philosophy with the universal commitment. Daoism hopes to use “Dao” to create the best environment for survival, and to fulfill individual responsibility for all (...) things in the world. This is a universal and open attitude towards values. The attraction of Daoist universal sentiment is that it takes ziran as its path, and “objectless desire”, “unprincipled knowing”, “non-coercive action” as ways and means to ensure the transfer of the universal value to all things, while ensuring that they realize their true values and make contributions to the whole society.

We establish two theorems concerning strongly compact cardinals and universal indestructibility for degrees of supercompactness. In the first theorem, we show that universal indestructibility for degrees of supercompactness in the presence of a strongly compact cardinal is consistent with the existence of a proper class of measurable cardinals. In the second theorem, we show that universal indestructibility for degrees of supercompactness is consistent in the presence of two non-supercompact strongly compact cardinals, each of which exhibits a significant amount of indestructibility (...) for its strong compactness.

The basic concept of Bentham's moral and political philosophy was public utility. He linked it directly with the concept of the universal interest, which comprises a distinctive partnership of the interests of all members of the community. The ultimate end of government and aim of all of morality is ‘the advancement of the universal interest’. This essay articulates the structure of Bentham's notion of universal interest and locates it in his theory of value.

Universal Grammar (UG) can be interpreted as a constraint on the form of possible grammars (hypothesis space) or as a constraint on acquisition strategies (selection procedures). In this response to Herschensohn we reiterate the position outlined in Epstein et al. (1996a, r), that in the evaluation of L2 acquisition as a UG- constrained process the former (possible grammars/ knowledge states) is critical, not the latter. Selection procedures, on the other hand, are important in that they may have a bearing on (...) development in language acquisition. We raise the possibility that differences in first and second language acquisition pertaining to both attainment of the end-state and course of development may derive from differences in selection procedures. We further suggest that for these reasons age effects in the attainment of nativelike proficiency must necessarily be separated from UG effects. (shrink)

It was accordingly recommended that government at the national, state and local levels show better commitment to the implementation of the (...) Universal Basic Education program. (shrink)

This article reviews the possible role of the universal basic income in the transformation of experience in gender and age perspectives. The universal basic income has been particularly hotly debated in recent decades. Regardless of the position, the common tone of the debates is the imperative “we must experiment.” Such a close interest in the universal basic income derives from the fact that it threatens to change the “generic” for humans situation of finiteness of resources and the need to work. (...) Thus, it is able to change the experience of what it means to be human. Since the universal basic income allows to separate labor from income, it is likely that its introduction will return value to the currently stigmatized or devalued types of labor, such as child care, elderly care or domestic work. It creates opportunities for experience redistribution in gender perspective: care and leaving, affective connection, and sensitivity could become the business of both parents, not just mothers. Another experience redistribution is possible in age perspective. Along with automation of labor, population ageing is a universal process that will sooner or later affect all the countries. Alarmist narratives that present this process as a threat and a problem now prevail. They are largely based on outdated ideas about old age and what it means to be old. However, in fact, ageing is the maturation of the population as a whole. With a proper re-evaluation of the meaning and significance of old age, the introduction of the universal basic income could create material conditions for the transfer of experience from the elderly to the younger – for the first time since traditional societies.

In this paper we prove that $\forall \textrm{FO}$, the universal fragment of first-order logic, is superfluous in $\varSigma _2^p$ and $\varPi _2^p$. As an example, we show that this yields a syntactic proof of the $\varSigma _2^p$-completeness of value-cost satisfiability. The superfluity method is interesting since it gives a way to prove completeness of problems involving numerical data such as lengths, weights and costs and it also adds to the programme started by Immerman and Medina about the syntactic approach in (...) the study of completeness.

ABSTRACT: How can we think about a universal ethics that could be adopted by any intelligent being, including the rising population of cyborgs, intelligent machines, intelligent algorithms or even potential extraterrestrial life? We generally give value to complex structures, to objects resulting from a long work, to systems with many elements and with many links finely adjusted. These include living beings, books, works of art or scientific theories. Intuitively, we want to keep, multiply, and share such structures, as well as (...) prevent their destruction. Such objects have value not because more information would simply mean more value. Instead, they have value because they require a long computational history, numerous interactions for their construction that we can assimilate to a computation, and they display what we call organized complexity. To propose the foundations of a universal ethics based on the intrinsic value of organized complexity, we first discuss conceptions of complexity, and argue that Charles Bennett’s logical depth is certainly a first approximation of what we are looking for. We then put forward three fundamental imperatives: to preserve, augment and recursively promote organized complexity. We show a broad range of applications with human, non-human and non-living examples. Finally, we discuss some specific issues of our framework such as the distribution of complexity, of managing copies and erasures, and how our universal ethics tackles classical ethical issues. In sum, we propose a clear, homogenous and consistent ethical foundation that can integrate many universal ethics desiderata. (shrink)

I argue that a reasonably comprehensive doctrine of human rights can be reconciled with at least a good deal of diversity in cultural belief and practice. The reconciliation cannot be achieved by trying to show that there is in fact a cross-cultural consensus about the existence of human rights, partly because no valid inference to the normative status of human rights can be drawn from the existence of such a consensus. However, by highlighting the premises rather than the conclusions of (...) normatively persuasive arguments for human rights, I argue that a reasonably comprehensive doctrine of universal human rights can be squared with what is known about the diversity of cultural beliefs and practices. This is because the (empirically plausible) denial that there is in fact a cross-cultural consensus about the existence of human rights can go hand-in-hand with cross-cultural endorsement of the normative considerations that underpin human rights doctrine.

We prove that each ∀1 free amalgamation class K over a finite relational language L admits a countable generic structure M isometrically embedding all countable structuresin K relative to a fixed metric. We expand L by infinitely many binary predicates expressingdistance, and prove that the resulting expansion of K has a model companion axiomatizedby the first-order theory of M. The model companion is non-finitely axiomatizable, evenover a strong form of the axiom scheme of infinity.

Tom Birch has decisively transformed the so-called “considerability” question by arguing that all things must be “considerable” from the start in “the root sense” if we are to determine what further kinds of value they may have. Spelling out this kind of “root” or “deep” consideration proves to be difficult, however, especially in light of post-Kantian conceptions of mind. Such consideration may also ask of the world too ready a kind of self-revelation. This paper proposes another, complementary version of universal (...) consideration: as a kind of practical invitation, as a way of creating the space within which a response can emerge or an exchange coevolve. I conclude by locating this vision within a picture of ethics as a whole that brings what I call its “originary” stage, rather than its formal stage, into focus. (shrink)

Globalism is probably the most frequently used term describing our current age. Found in many contexts, it is often a vague concept referring to a host of different figurations of post-industrial society. European expansion, the growth of the global economy, mass immigration and the planetary expansion of international relations are merely some of the phenomena associated with globalism. Yet globalism taken in its most neutral form of global history is not merely a trendy catch-all phrase for the challenges of our (...) age but has its origins in the efforts of the enlightenment—to rewrite the theological universal histories of the Middle Ages. There is a close relationship between the historiography of universal history and the current ideology of globalism. By juxtaposing the two main strands of universal history (the universal history of mankind vs. the cyclical history of individual peoples) to the problem of European identity, I show that the theoretical problems which caused the demise of universal history continue to plague globalism. Such an analysis of the ideological foundations of globalism is central not only to the current debate on the (re-) construction of European history, but also in the discussion on what constitutes European ideas. ☆ This essay is a revised version of a talk held at the Society for the Humanities, Cornell University, in the Fall of 2005.

Tarski [19] proved the important theorem that the class of representable relation algebras is equationally axiomatizable. One of the key steps in his proof is showing that the class of (isomorphs of) simple set relation algebras—that is, algebras of binary relations with a unit of the formU×Ufor some non-empty setU—is universal, i.e., is axiomatizable by a set of universal sentences. In the same paper Tarski observed that the class of (isomorphs of) relation algebras constructed from groups (so-calledgroup relation algebras) is (...) also universal.We shall abstract the essential ingredients of Tarski's method (in Corollary 2.4), and then combine them with some observations about atom structures, to establish (in Theorem 2.6) a rather general method for showing that certain classes of simple relation algebras—and, more generally, certain classes of simple algebras in a discriminator variety V—are universal, and consequently that the collections of (isomorphs of) subdirect products of algebras in such classes form subvarieties of V. As applications of the method we show that two well-known classes of simple relation algebras, those constructed from projective geometries (sometimes calledLyndon algebras) and those constructed from modular lattices with a zero (sometimes calledMaddux algebras), are universal. In the process we prove that these two classes consist precisely of all (isomorphs of) complex algebras over the respective geometries and modular lattices, provided that we choose the primitive notions of the latter structures in an appropriate fashion. We also derive Tarski's theorems and a related theorem of the author as easy corollaries of Theorem 2.6. (shrink)

We show that certain classes of modules have universal models with respect to pure embeddings: Let R be a ring, T a first‐order theory with an infinite model extending the theory of R‐modules and (where ⩽pp stands for “pure submodule”). Assume has the joint embedding and amalgamation properties. If or, then has a universal model of cardinality λ. As a special case, we get a recent result of Shelah [28, 1.2] concerning the existence of universal reduced torsion‐free abelian groups with (...) respect to pure embeddings.We begin the study of limit models for classes of R‐modules with joint embedding and amalgamation. We show that limit models with chains of long cofinality are pure‐injective and we characterize limit models with chains of countable cofinality. This can be used to answer [18, Question 4.25].As this paper is aimed at model theorists and algebraists an effort was made to provide the background for both. (shrink)

Recent advances in genetics and neurobiology have greatly increased the degree of variation that one finds in what is taken to provide the biological foundations of our species-specific linguistic capacities. In particular, this variation seems to cast doubt on the purportedly homogeneous nature of the language faculty traditionally captured by the concept of “Universal Grammar.” In this article we discuss what this new source of diversity reveals about the biological reality underlying Universal Grammar. Our discussion leads us to support (1) (...) certain hypotheses advanced in evolutionary developmental biology that argue for the existence of robust biological mechanisms capable of canalizing variation at different levels, and (2) a bottom-up perspective on comparative cognition. We conclude by sketching future directions for what we call “comparative biolinguistics,” specifying which experimental directions may help us succeed in this new research avenue. (shrink)

Universal social institutions, such as marriage, commons management and property, have emerged independently in radically different cultures. This requires explanation. As Boyer and Petersen point out ‘in a purely localist framework would have to constitute massively improbable coincidences’ . According to Boyer and Petersen, those institutions emerged naturally out of genetically wired behavioural dispositions, such as marriage out of mating strategies and borders out of territorial behaviour. While I agree with Boyer and Petersen that ‘unnatural’ institutions cannot thrive, this one-sided (...) explanation of universal social institutions in terms of genetic human nature is unsatisfactory. Drawing on the literature on multi-level selection and gene-culture coevolution, I argue that universal social institutions are first and foremost the products of cultural selection. They occupy fitness peaks in the landscape of cultural possibilities, much in the same way that biological adaptations occupy fitness peaks in the landscape of biological possibilities. To show this, I use game-theory. By modelling the domains of social interaction in which marriage, commons management, and property emerged as Prisoner’s dilemma situations, it becomes clear how an institutional framework allows the group to move to an interactive equilibrium with a larger payoff. Institutions do so by incentivising all parties to adopt a cooperative strategy. They are culturally selected ways of optimising genetically constrained domains of human social interaction. (shrink)

Numerous sex differences in obsessive-compulsive disorder (OCD) instantiations are likely universal, as the associated evolutionary threats and concerns onto which they map were differentially important to the two sexes. Hence, although some ritualized behaviors or thoughts are indeed culture-specific, others are both culturally and temporally invariant as they are rooted in universal Darwinian etiologies (e.g., the sex differences in OCD symptomatology posited here).

Among the many vivid metaphors in Darwin’s Dangerous Idea, one stands out. The understanding of how cumulative natural selection gives rise to adaptations is, Dennett says, like a “universal acid”—an idea so powerful and corrosive of conventional wisdom that it dissolves all attempts to contain it within biology. Like most good ideas, this one is very simple: Once replicators (material objects that are faithfully copied) come to exist, some will replicate more rapidly than others, leading to adaptation by natural selection. (...) The great power of the idea is that the resulting adaptations can be understood by asking what leads to efficient, rapid replication. Given that ideas seem to replicate, it is natural that Dawkins (1976, 1982), Dennett (1992), and others have explored the possibility of using this idea to explain cultural evolution. (shrink)

We discuss the existence of universal spaces (either in the sense of embeddings or continuous images) for some classes of scattered Eberlein compacta. Given a cardinal κ, we consider the class Sκ of all scattered Eberlein compact spaces K of weight ≤ κ and such that the second Cantor-Bendixson derivative of K is a singleton. We prove that if κ is an uncountable cardinal such that κ = 2<κ, then there exists a space X in Sκ such that every member (...) of Sκ is homeomorphic to a retract of X. We show that it is consistent that there does not exist a universal space (either by embeddings or by mappings onto) in Sω₁. Assuming that ∂ = ω₁, we prove that there exists a space X ∈ Sω₁, which is universal in the sense of embeddings. We also show that it is consistent that there exists a space X ∈ Sω₁, universal in the sense of embeddings, but Sω₁ does not contain an universal element in the sense of mappings onto. (shrink)
