This paper argues that the plethora of experiments with decentralized social technologies (DSTs)—clusters of which are sometimes called “the Web 3.0 ecosystem” or “the Fediverse”—have brought us to a constitutional moment. These technologies enable radical innovations in social, economic, and political institutions and practices, with the potential to support transformative approaches to political economy. They demand governance innovation. The paper develops a framework of prudent vigilance for making ethical choices in this space that help to both grasp positive opportunities for (...) transformation and avoid the potentially problematic consequences. Most of our specific examples and concerns come from the blockchain/Web3 universe, as this has received the greatest investment, attention, and adoption to date. However, we aim to offer a framework for governance decision-making in conditions of uncertainty that applies more broadly to other DSTs. Specifically, under the framework of prudent vigilance, we propose a pragmatic, democratic, and pluralist approach to navigating bold experimentation with social practices and political economy enabled by these technologies. Our overarching goal is to provide a framework open to transformative improvement and constrained by guardrails and guiding values supportive of democracy, freedom, and pluralism. We take a relatively strong position, rather than simply laying out ethical issues and potential approaches. We seek to be provocative in order to spur further work and hope this paper will serve as a first bridge between academic philosophy and the DST community, which have hardly interacted to date.

On rationalist infallibilism, a wide range of both (i) analytic and (ii) synthetic a priori propositions can be infallibly justified (or absolutely warranted), i.e., justified to a degree that entails their truth and precludes their falsity. Though rationalist infallibilism is indisputably running its course, adherence to at least one of the two species of infallible a priori justification refuses to disappear from mainstream epistemology. Among others, Putnam (1978) still professes the a priori infallibility of some category (i) propositions, while Burge (...) (1986, 1988, 1996) and Lewis (1996) have recently affirmed the a priori infallibility of some category (ii) propositions. In this paper, I take aim at rationalist infallibilism by calling into question the a priori infallibility of both analytic and synthetic propositions. The upshot will be twofold: first, rationalist infallibilism unsurprisingly emerges as a defective epistemological doctrine, and second, more importantly, the case for the a priori infallibility of one or both categories of propositions turns out to lack cogency.

Minimalism is currently the received deflationary theory of truth. On minimalism, truth is a transparent concept and a deflated property of truth bearers. In this paper, I situate minimalism within current deflationary debate about truth by contrasting it with its main alternative―the redundancy theory of truth. I also outline three of the primary challenges facing minimalism, its formulation, explanatory adequacy and stability, and draw some lessons for the soundness of its conception of truth.

On rationalist infallibilism, a wide range of both (i) analytic and (ii) synthetic a priori propositions can be infallibly justified, i.e., justified in a way that is truth-entailing. In this paper, I examine the second thesis of rationalist infallibilism, what might be called ‘synthetic a priori infallibilism’. Exploring the seemingly only potentially plausible species of synthetic a priori infallibility, I reject the infallible justification of so-called self-justifying propositions.

According to Field’s influential incompleteness objection, Tarski’s semantic theory of truth is unsatisfactory since the definition that forms its basis is incomplete in two distinct senses: (1) it is physicalistically inadequate, and for this reason, (2) it is conceptually deficient. In this paper, I defend the semantic theory of truth against the incompleteness objection by conceding (1) but rejecting (2). After arguing that Davidson and McDowell’s reply to the incompleteness objection fails to pass muster, I argue that, within the constraints (...) of a non-reductive physicalism and a holism concerning the concepts of truth, reference and meaning, conceding Field’s physicalistic inadequacy conclusion while rejecting his conceptual deficiency conclusion is a promising reply to the incompleteness objection.

Linguistic competence, in general terms, involves the ability to learn, understand, and speak a language. The nativist view in the philosophy of linguistics holds that the principal foundation of linguistic competence is an innate faculty of linguistic cognition. In this paper, close scrutiny is given to nativism's fundamental commitments in the area of metaphysics. In the course of this exploration it is argued that any minimally defensible variety of nativism is, for better or worse, married to two theses: linguistic competence (...) is grounded in a faculty of linguistic cognition that is (i) embodied and (ii) whose operating rules are represented in the brains of human language users.

The superassertability theory of truth, inspired by Crispin Wright (1992, 2003), holds that a statement is true if and only if it is superassertable in the following sense: it possesses warrant that cannot be defeated by any improvement of our information. While initially promising, the superassertability theory of truth is vulnerable to a persistent difficulty highlighted by James Van Cleve (1996) and Terrence Horgan (1995) but not properly fleshed out: it is formally illegitimate in a similar sense that unsophisticated epistemic (...) theories of truth are widely acknowledged to be. Sustained analysis reveals that the unrestricted formal legitimacy argument is firmly grounded in first person conceivability evidence. (shrink)

The weak deflationist about truth is committed to two theses: one conceptual, the other ontological. On the conceptual thesis (what might be called a ‘triviality thesis’), the content of the truth predicate is exhausted by its involvement in some version of the ‘truth-schema’. On the ontological thesis, truth is a deflated property of truth bearers. In this paper, I focus on weak deflationism’s ontological thesis, arguing that it generates an instability in its view of truth: the view threatens to collapse (...) into either that of strong deflationism (i.e., truth is not a property) or that of some form of inflationism (i.e., truth is a substantial property). The instability objection to weak deflationism is sketched by way of a truth-property ascription dilemma, the two horns of which its proponent is at pains to circumvent. (shrink)

Beauchamp and Childress created the ‘four principle’ approach to help clinicians analyse and resolve ethical dilemmas they may encounter when working.

Cyborgs are ongoing becomings of a doubly “in-between” temporality of humans and machines. Materially made from components of both sorts of beings, cyborgs gain increasing function through an interweaving in which each alters the other, from the level of “neural plasticity” to software updates to emotional breakthroughs of which both are a part. One sort of temporal in-between is of the progressive unfolding of a deepening becoming as “not-one-not-two” and the other is a “doubling back” of time into itself in (...) which moments that were once disparate are conjoined or enjambed. Tracing the experience of Michael Chorost during a four year period of coming to terms with his cochlear implant, related in Rebuilt: How Becoming Part Computer Made Me More Human, the essay pinpoints shifts in awareness, perceptual belief, and being-with others that unfold within the in-between of person and machine.

This essay discusses how our traditional ethics may harbor assumptions that place humans in a position in which overt violence towards animals is an almost inevitable outcome since their formulation involves violence towards ourselves and our animal fellows in our cutting our embodied ties with them. The essay explores Derrida’s Animal that Therefore, I Am, in its detailing of the two discourses within European intellectual history of those who felt they were “above” animals and were not addressed by them versus (...) those who could acknowledge that animals do address us. Derrida also cites the “lyconomy” of this tradition that brandishes the image of the “wolf” within us as a streak of rapacious violence that we can only fight with violence, thus projecting onto the wolf a false identity to justify our own demons of violence. Merleau-Ponty’s notions of embodiment further this idea that we are enmeshed with animals in a basic affective, perceptual and visceral way and that to ignore this interweaving of lives is to do violence to ourselves as well as violence towards them. I then cite ethologists for evidence that wolves are one of the most social, non-violent animals on the planet and detail how two million were slaughtered in the name of eradicating an “evil” being. Such behavior on our part I call “speciocide,” as heinous as genocide. Finally, phenomenology, as one particular philosophical approach, may have a critical edge in helping us to see our animal fellows more clearly, to understand them better, and discern our truer moral obligations to them.

This essay details wolves’ sense of their surround in terms of how wolves’ perceptual acuities, motor abilities, daily habits, overriding concerns, network of intimate social bonds and relationship to prey gives them a unique sense of space, time, belonging with other wolves, memorial sense, imaginative capacities, dominant emotions (of affection, play, loyalty, hunger, etc.), communicative avenues, partnership with other creatures, and key role in ecological thriving. Wolves are seen to live within a vast sense of aroundness and closeness to aspects (...) of their surround (compared to humans), a highly charged intimacy and cooperation with other wolves, and a caring and non-aggressive attitude that goes beyond the pack, despite their loyalty and defense of territory. The cultural myths and history that absurdly demonize the wolf are explored in their self-righteous attempts to exterminate wolves, which I call “speciocide” and probe for projections of human viciousness. The supposed rapaciousness of wolves is re-examined by expanding Barry Lopez’s sense of the silent dialogue of death with other creatures to be reconsidered as a kind of respect, assertion of vitality, recognition or mortality and cooperation.

The critique of tourism as being only a distanced, detached, and consumerist passing through of foreign landscapes and cultures isdisputed in this essay. The idea that tourism necessarily fits the paradigm of inauthenticity as the tranquilized and alienated hopping from spot to spot in prepackaged, superficial presentations is contrasted with another sense of tourism as drawing upon the potential power of the glance to disrupt the everyday, to focus on the particular, to be surprised by the new, and to bodily (...) join up with the rhythms of place being as shifting. Authenticity is seen in both Heidegger and Merleau-Ponty to be primarily about a greater bodily awareness of surround and transformation of the self as an ongoing process of “selving” that yields a more singular sense of who one is in relationship to places and their interconnectedness. To gain a better sense of oneself in one own being or uniqueness is to gain more meaning through emplacement within the surround. The glance at a new world can open up an “interplace” which expands anddeepens the sense of who we are in the interconnection and reverberations among places. (shrink)

Once known as the city of silk, Suzhou 苏州 has become the centre of wedding dress production, selling paradise on earth for one day, including copies of the last royal wedding dress, out of shops at the foot of mythic Tiger Hill.

It has attracted millions of migrants searching for a better future; millions of tourists visit every year to experience the past, strolling through (...) the gardens and courtyards of its Old Town.

Many claims about conceptual matters are often represented as, or inferred from, claims about the meaning, reference, or mastery, of words. But sometimes this has led to treating conceptual analysis as though it were nothing but linguistic analysis. We canvass the most promising justifications for moving from linguistic premises to substantive conclusions. We show that these justifications fail and argue against current practice (in metaethics and elsewhere), which confuses an investigation of a word’s meaning, reference, or competence conditions with an (...) analysis of some concept or property associated with that word.

When product design teams gather at the whiteboard in big-tech office parks and startup garages around the world, they ask themselves: How will customers use our technology? Is it better than our competitors’? How much money can we make? But one question that’s rarely asked: does our technology advance human flourishing? -/- In a new white paper by Harvard professor Danielle Allen and her colleagues Eli Frankel, Woojin Lim, Divya Siddarth, Josh Simons, and Glen Weyl entitled “The Ethics (...) of Decentralized Social Technologies: Lessons from Web3, the Fediverse, and Beyond,” the authors not only ask this question but offer a powerful framework for answering it. Drawing on the accumulated wisdom of democratic societies, the authors show that the values of democratic governance that have promoted human flourishing can be translated into a rubric for judging new technologies. -/- In this short research brief, we unpack and comment on the four-step logic at the core of their case. Ultimately, their argument demonstrates the power and the challenge – and above all, the urgency – of placing human flourishing at the center of technology governance. (shrink)

Hermann Weyl was one of the most important figures involved in the early elaboration of the general theory of relativity and its fundamentally geometrical spacetime picture of the world. Weyl’s development of “pure infinitesimal geometry” out of relativity theory was the basis of his remarkable attempt at unifying gravitation and electromagnetism. Many interpreters have focused primarily on Weyl’s philosophical influences, especially the influence of Husserl’s transcendental phenomenology, as the motivation for these efforts. In this article, I argue (...) both that these efforts are most naturally understood as an outgrowth of the distinctive mathematical-physical tradition in Göttingen and also that phenomenology has little to no constructive role to play in them.

A new form of skepticism is described, which holds that objectivity and understanding are incompossible ideals of modern science. This is attributed to Weyl, hence its name: Weylean skepticism. Two general defeat strategies are then proposed, one of which is rejected.

The appearance of negative terms in quasiprobability representations of quantum theory is known to be inevitable, and, due to its equivalence with the onset of contextuality, of central interest in quantum computation and information. Until recently, however, nothing has been known about how much negativity is necessary in a quasiprobability representation. Zhu :120404, 2016) proved that the upper and lower bounds with respect to one type of negativity measure are saturated by quasiprobability representations which are in one-to-one correspondence with the (...) elusive symmetric informationally complete quantum measurements. We define a family of negativity measures which includes Zhu’s as a special case and consider another member of the family which we call “sum negativity.” We prove a sufficient condition for local maxima in sum negativity and find exact global maxima in dimensions 3 and 4. Notably, we find that Zhu’s result on the SICs does not generally extend to sum negativity, although the analogous result does hold in dimension 4. Finally, the Hoggar lines in dimension 8 make an appearance in a conjecture on sum negativity. (shrink)

Glen Pettigrove's work enlarges my own thinking on forgiveness. In this review, I argue for even more attention to some philosophical connections that I suggest he neglects. But it is undeniably the case that Pettigrove advances a new view of forgiveness, taking the results of his analysis of the utterance, “I forgive you,” to inform a “broader definition that encompasses a wider range of experiences” than are accommodated by predominant conceptions of forgiveness as an emotional state (151). Philosophers interested (...) in moral emotions and moral practices should read this book in order to have a fuller sense of the state of forgiveness studies and the possibilities for thinking about forgiveness in its many manifestations. Philosophers who are already very familiar with the literature on forgiveness will find that Pettigrove takes up exceptionally detailed discussion of forgiveness as it relates to understanding, love, grace, gratitude, and desert.

Brouwer’s intuitionism was a far-reaching attempt to reform the foundations of mathematics. While the mathematical community was reluctant to accept Brouwer’s work, its response to later-developed brands of intuitionism, such as those presented by Hermann Weyl and Arend Heyting, was different. The paper accounts for this difference by analyzing the intuitionistic versions of Brouwer, Weyl, and Heyting in light of a two-tiered model of the body and image of mathematical knowledge. Such a perspective provides a richer account of (...) each story and points to a possible connection between the community’s reaction and the changes each mathematician had proposed. (shrink)

In this article I develop an elementary system of axioms for Euclidean geometry. On one hand, the system is based on the symmetry principles which express our a priori ignorant approach to space: all places are the same to us, all directions are the same to us and all units of length we use to create geometric figures are the same to us. On the other hand, through the process of algebraic simplification, this system of axioms directly provides the (...) class='Hi'>Weyl’s system of axioms for Euclidean geometry. The system of axioms, together with its a priori interpretation, offers new views to philosophy and pedagogy of mathematics: it supports the thesis that Euclidean geometry is a priori, it supports the thesis that in modern mathematics the Weyl’s system of axioms is dominant to the Euclid’s system because it reflects the a priori underlying symmetries, it gives a new and promising approach to learn geometry which, through the Weyl’s system of axioms, leads from the essential geometric symmetry principles of the mathematical nature directly to modern mathematics.

Prominent constructive theories of sets as Martin-Löf type theory and Aczel and Myhill constructive set theory, feature a distinctive form of constructivity: predicativity. This may be phrased as a constructibility requirement for sets, which ought to be finitely specifiable in terms of some uncontroversial initial “objects” and simple operations over them. Predicativity emerged at the beginning of the 20th century as a fundamental component of an influential analysis of the paradoxes by Poincaré and Russell. According to this analysis the paradoxes (...) are caused by a vicious circularity in definitions; adherence to predicativity was therefore proposed as a systematic method for preventing such problematic circularity. In the following, I sketch the origins of predicativity, review the fundamental contributions by Russell and Weyl and look at modern incarnations of this notion. (shrink)

Detlefsen (1986) reads Hilbert's program as a sophisticated defense of instrumentalism, but Feferman (1998) has it that Hilbert's program leaves significant ontological questions unanswered. One such question is of the reference of individual number terms. Hilbert's use of admittedly "meaningless" signs for numbers and formulae appears to impair his ability to establish the reference of mathematical terms and the content of mathematical propositions (Weyl (1949); Kitcher (1976)). The paper traces the history and context of Hilbert's reasoning about signs, which (...) illuminates Hilbert's account of mathematical objectivity, axiomatics, idealization, and consistency.

One of the key episodes of history of modern physics – Paul Dirac’s startling contrivance of the relativistic theory of the electron – is elicited in the context of lucid epistemological model of mature theory change. The peculiar character of Dirac’s synthesis of special relativity and quantum mechanics is revealed by comparison with Einstein’s sophisticated methodology of the General Relativity contrivance. The subtle structure of Dirac’s scientific research program and first and foremost the odd principles that put up its powerful (...) heuristics is scrutinized with special emphasis on the highly controversial tenet of “mathematical beauty.” It is contended that despite the relentless Dirac’s remarks denigrating the controversial role of philosophy one can trace its indirect influence through Arthur Eddington’s and Hermann Weyl’s whimsical mathematical models. Accordingly, the milestones of Dirac’s research programme realization in the distinctive context of the applied epistemological doctrine are indicated. (shrink)

We often speak of 'Eastern' and 'Western' philosophy, yet it is not always easy to distinguish the key factors that justify this distinction. This essay explores the two very different conceptions of the continuum that underlie these traditions of thought and knowledge. The views of Hermann Weyl are given and it is proposed they are correct. Attention is drawn to the mutually-exclusive visions of the continuum that separate the philosophies of East and West, for they offer us a way (...) of pinning down a definition of these vague geographical terms so as to give them, in at least one respect, a clear philosophical and scientific meaning.

Using the concepts of epistemic virtue and vice as defined by José Medina, and reciprocal recognition as outlined by Glen Coulthard, I argue that the Canadian state is currently in a non-reciprocal relationship with Indigenous peoples as a result of epistemic failure on the part of the state. This failure involves a surfacelevel recognition of Indigenous peoples at the same time as the manifestation of the epistemic vices of arrogance, laziness and closed-mindedness. The epistemic injustice framework alongside a critique (...) of the politics of recognition can help shed light on what is going wrong betweenthe settler state and Indigenous peoples. Moreover, by appealing to grounded normativity, an Indigenous ethical framework, I argue that a land-based ethics of reciprocity can help us move toward reciprocal recognition and equality, if we are epistemically humble, curious and open-minded to it.

ABSTRACT Glen Pettigrove addresses the proportionality principle in ethics, the principle that ‘our actions, attitudes, or emotions should be proportional to the degree of value present in the object or events to which they are responding’. He argues this is inconsistent with some familiar features of common-sense morality. In response, he brings virtuous character into the picture, a move we support but wish to modify. We show that certain helping actions should be guided by whether one has the virtue (...) profile most suited to the situation from among a surrounding network of people. (shrink)

Predicativity is a notable example of fruitful interaction between philosophy and mathematical logic. It originated at the beginning of the 20th century from methodological and philosophical reflections on a changing concept of set. A clarification of this notion has prompted the development of fundamental new technical instruments, from Russell's type theory to an important chapter in proof theory, which saw the decisive involvement of Kreisel, Feferman and Schütte. The technical outcomes of predica-tivity have since taken a life of their own, (...) but have also produced a deeper understanding of the notion of predicativity, therefore witnessing the " light logic throws on problems in the foundations of mathematics. " (Feferman 1998, p. vii) Predicativity has been at the center of a considerable part of Feferman's work: over the years he has explored alternative ways of explicating and analyzing this notion and has shown that predicative mathematics extends much further than expected within ordinary mathematics. The aim of this note is to outline the principal features of predicativity, from its original motivations at the start of the past century to its logical analysis in the 1950-60's. The hope is to convey why predicativity is a fascinating subject, which has attracted Feferman's attention over the years. (shrink)

The current technoscientific progress has led to a sectorization in the philosophy of science. Today the philosophy of science isn't is informal interested in studying old problems about the general characteristics of scientific practice. The interest of the philosopher of science is the study of concepts, problems and riddles of particular disciplines. Then, within this progress of philosophy of science, neuroscientific research stands out, because it invades issues traditionally addressed by the humanities, such as the nature of consciousness, action, knowledge, (...) normativity, etc. As a result, the new area of interdisciplinary study of neuroscience and philosophy arises: neurophilosophy. This emerging area applies neuroscientific concepts to traditional philosophical questions, limiting their responses to neuroscientific revelations about nervous systems. Neurophilosophy research focuses on problems related to the indirect nature of mind and brain, computational or representative analysis of brain process, relationships between psychological and neuroscientific research, adequate adaptations of physical and philosophical concepts in neuroscience and the place of cognitive functions. Now, the temporal representation of conscious experience and the types of the neural architecture to represent objects in time have aroused scientific interest. Under these interests, we focus on the studies on the temporary triadic structure of phenomenological consciousness in Dan Lloyd and Rick Grush. From Grush’s studies, the importance of Kantian ideas for cognitive neuroscience emerges, due to the active way in which Kant conceived space and time as forms of intuition, within which the mind interprets its experience. Under this perspective, the theoretical arguments of Dennett-Kinsbourne and Eagleman-Sejnowski represent winks in the direction of Kant-Husserl within the neuroscientific goal while considering that the contents provided by the mind included space, objects and perception of causal relationships. Then, theories of cognitive neuroscience are beginning to suggest that these elements are also, as Kant argued, interpretative elaborations provided by mind / brain, and not only content received from outside. In other words, current cognitive neuroscientific theories try to pass from its Humean phase to a Kantian phase. So, the challenge has been to explain that these elements are provided by the mind and the world itself, and how they have the content they have come from. These are lacking in current studies. Filling this gap helps to involve the analysis of the scientist’s experience in his theoretical attitude. In this sense, an investigation under the Kantian-Husserlian approach that involves pure intuitions a priori with the experience of the scientific and neuroscientific concepts represents a ground-breaking. At present, a neurophilosophical study about this does not exist. In this sense, one feasible proposal for research would be based on the application of neuroscientific results of Moser-Britt to philosophical problems of foundational notions in relativistic physics: space, time, space-time, field, etc., under the Kantian-Husserlian approach, which allows to demonstrate the multidisciplinary link between neurophilosophy and physics. This represents a ground-breaking area in current interests in scientific research, with a positive impact in the field of neuroscience, and contributing to the study of abstraction emphasizing the importance of Kant’s Copernican turn and Husserl’s phenomenological ideas in the construction of physical theories. -/- .

In a quantum universe with a strong arrow of time, it is standard to postulate that the initial wave function started in a particular macrostate---the special low-entropy macrostate selected by the Past Hypothesis. Moreover, there is an additional postulate about statistical mechanical probabilities according to which the initial wave function is a ''typical'' choice in the macrostate. Together, they support a probabilistic version of the Second Law of Thermodynamics: typical initial wave functions will increase in entropy. Hence, there are two (...) sources of randomness in such a universe: the quantum-mechanical probabilities of the Born rule and the statistical mechanical probabilities of the Statistical Postulate. I propose a new way to understand time's arrow in a quantum universe. It is based on what I call the Thermodynamic Theories of Quantum Mechanics. According to this perspective, there is a natural choice for the initial quantum state of the universe, which is given by not a wave function but by a density matrix. The density matrix plays a microscopic role: it appears in the fundamental dynamical equations of those theories. The density matrix also plays a macroscopic / thermodynamic role: it is exactly the projection operator onto the Past Hypothesis subspace. Thus, given an initial subspace, we obtain a unique choice of the initial density matrix. I call this property "the conditional uniqueness" of the initial quantum state. The conditional uniqueness provides a new and general strategy to eliminate statistical mechanical probabilities in the fundamental physical theories, by which we can reduce the two sources of randomness to only the quantum mechanical one. I also explore the idea of an absolutely unique initial quantum state, in a way that might realize Penrose's idea of a strongly deterministic universe. (shrink)
