    Data as asset? The measurement, governance, and valuation of digital personal data by Big Tech.Callum Ward, D. T. Cochrane & Kean Birch - 2021 - Big Data and Society 8 (1).
    Digital personal data is increasingly framed as the basis of contemporary economies, representing an important new asset class. Control over these data assets seems to explain the emergence and dominance of so-called “Big Tech” firms, consisting of Apple, Microsoft, Amazon, Google/alphabet, and Facebook. These US-based firms are some of the largest in the world by market capitalization, a position that they retain despite growing policy and public condemnation—or “techlash”—of their market power based on their monopolistic control of personal data. We (...)

  4. Lawful Humean explanations are not circular.Callum Duguid - 2021 - Synthese 199 (3-4):6039-6059.
    A long-standing charge of circularity against regularity accounts of laws has recently seen a surge of renewed interest. The difficulty is that we appeal to laws to explain their worldly instances, but if these laws are descriptions of regularities in the instances then they are explained by those very instances. By the transitivity of explanation, we reach an absurd conclusion: instances of the laws explain themselves. While drawing a distinction between metaphysical and scientific explanations merely modifies the challenge rather than (...)

    Becoming and Being a Person through Others: African Philosophy’s Ubuntu and Aquinas’ mutual Indwelling in Comparative Discourse.Callum David Scott - 2023 - Revista Portuguesa de Filosofia 79 (1-2):749-778.
    African Philosophy and St Thomas Aquinas have both been taught in African universities, but the engagement between the continent’s indigenous philosophical tradition and the Catholic intellectual tradition’s preeminent strand, has not been thorough. Presupposing that plural philosophical traditions contribute to the search to better understand, this research embarks upon a comparative analysis of the perspectives of the African ubuntu philosophy and Thomist philosophical conceptualisations of human becoming and being. Through analysis of dimensions of both traditions, it is contended that human (...)

    History and Historiography in Classical Utilitarianism, 1800–1865.Callum Barrell - 2021 - Cambridge University Press.
    This first comprehensive account of the utilitarians' historical thought intellectually resituates their conceptions of philosophy and politics, at a time when the past acquired new significances as both a means and object of study. Drawing on published and unpublished writings - and set against the intellectual backdrops of Scottish philosophical history, German and French historicism, romanticism, positivism, and the rise of social science and scientific history - Callum Barrell recovers the depth with which Jeremy Bentham, James Mill, George Grote, (...)

    Left Populism and the Education of Desire.Callum McGregor - 2024 - Studies in Philosophy and Education 43 (1):73-90.
    This paper mobilises the psychoanalytic concepts of desire and enjoyment to better understand how processes of education aimed at extending and defending democratic life might respond to and engage with populist politics. I approach this task by engaging with a particular vector of Mouffe and Laclau’s political philosophy, moving from a critique of liberal democracy’s rationalist pretensions to their insistence that left populism and its passionate construction of a ‘people’ is the central task facing radical politics. This attention to the (...)

    Building between past and future: Nostalgia, historical materialism and the architecture of memory in Baltimore’s Inner Harbor.Callum Ingram - 2015 - Philosophy and Social Criticism 41 (3):317-333.
    To balance radical changes in the built environment that accompany urban renewal, many cities deploy historical design elements to provoke a sense of physical and temporal continuity. By examining the theory and practice of nostalgia in renewal projects, I argue that this strategic deployment of historical signifiers is more complex and normatively problematic than it first appears. Analysing the design and construction of Baltimore’s Oriole Park at Camden Yards through Walter Benjamin’s theories of cultural production and historical succession, I show (...)

    The Reader and the Redeemer.Callum Ingram - 2015 - Contemporary Pragmatism 12 (2):232-250.
    I examine the effort that some theorists make to write to, and inspire a new sense of agency in, their readers. I will consider the work of John Dewey and Hannah Arendt, two theorists who attempt to close the gap between political reality and a theoretically informed politics by using their texts to rethink and recreate their reader. By working between a determined past and the possibility of a redeemed future, Dewey and Arendt use their theory to implant a sense (...)

    Graph Theory and The Identity of Indiscernibles.Callum Duguid - 2016 - Dialectica 70 (3):463-474.
    The mathematical field of graph theory has recently been used to provide counterexamples to the Principle of the Identity of Indiscernibles. In response to this, it has been argued that appeal to relations between graphs allows the Principle to survive the counterexamples. In this paper, I aim to show why that proposal does not succeed.

    Symmetries as Humean Metalaws.Callum Duguid - forthcoming - Philosophy of Science 90 (1):171-187.
    Symmetry principles are a central part of contemporary physics, yet there has been surprisingly little metaphysical work done on them. This article develops the Wignerian treatment of symmetries as higher-order laws—metalaws—within a Humean framework of lawhood. Lange has raised two obstacles to Humean metalaws, and the article shows that the account has the resources available to respond to both. It is argued that this framework for Humean metalaws stands as an example of naturalistic metaphysics, able to bring Humeanism into contact (...)

    Simplified Lower Bounds for Propositional Proofs.Alasdair Urquhart & Xudong Fu - 1996 - Notre Dame Journal of Formal Logic 37 (4):523-544.
    This article presents a simplified proof of the result that bounded depth propositional proofs of the pigeonhole principle are exponentially large. The proof uses the new techniques for proving switching lemmas developed by Razborov and Beame. A similar result is also proved for some examples based on graphs.

    Communists, Anarchists, and Suckers: A Reply to Spafford on ‘Conditional Exchange’.Callum Zavos MacRae - 2023 - Journal of Value Inquiry 57 (3):477-485.
    In a recent paper in JVI, ‘An Anarchist Interpretation of Marx’s “Ability to Needs” Principle,’ Spafford has argued that: (i) the communist and anarchist traditions share an objection to a particular kind of exchange (which he calls quid pro quo exchange); (ii) the anarchist objection to quid pro quo exchange can be understood as opposition to conditional exchange; (iii) consequently, the objection motivates an opposition to conditional exchange as such (i.e. a commitment to unconditional exchange); and (iv) we can construct (...)

    Higher-Order Awareness of What?Callum Zavos MacRae - 2023 - Erkenntnis 88 (5):2083-2095.
    According to the Higher-Order Thought (HOT) theory of consciousness, conscious states are just those states that are the object of a suitable higher-order thought to the effect that one is in that state. These higher-order thoughts perform this role by providing subjects with a particular type of _awareness_. However, HOT theorists have tended to offer two alternative formulations of this awareness when stating the basic claims of HOT theory. According to what I call the _state formulation_ of HOT theory, HOTs (...)

    Corruption, South African Multinational Enterprises and Institutions in Africa.John M. Luiz & Callum Stewart - 2014 - Journal of Business Ethics 124 (3):383-398.
    We examine the responses of South African multinational enterprises to corruption in African markets in the context of institutional voids. Corruption is a source of uncertainty and additional transactional costs for MNEs and it necessitates a strategic response. The research employs a qualitative study of a sample of MNEs with experience in internationalising into Africa. The results indicate that corruption in African markets is pervasive and closely associated with the institutional voids in these countries. MNEs see themselves as ‘institution takers’ (...)

    The frontiers of empirical science: A Thomist-inspired critique of scientism.Callum Scott - 2016 - HTS Theological Studies 72 (3).
    Scientistic conceptualisations hold to the positivistic positions that science is limitless in its potential representations of material phenomena and that it is the only sure path to knowledge. In recent popular scientific literature, these presuppositions have been reaffirmed to the detriment of both philosophy and theology. This article argues for the contrary position by a meta-analysis of empirical science from a Thomist perspective. Identifying empirical science as limited in its method and bound to the material sphere of being alone, we (...)

    The poverty of ethical AI: impact sourcing and AI supply chains.James Muldoon, Callum Cant, Mark Graham & Funda Ustek Spilda - forthcoming - AI and Society:1-15.
    Impact sourcing is the practice of employing socio-economically disadvantaged individuals at business process outsourcing centres to reduce poverty and create secure jobs. One of the pioneers of impact sourcing is Sama, a training-data company that focuses on annotating data for artificial intelligence (AI) systems and claims to support an ethical AI supply chain through its business operations. Drawing on fieldwork undertaken at three of Sama’s East African delivery centres in Kenya and Uganda and follow-up online interviews, this article interrogates Sama’s (...)

  25. The death of Philosophy: A response to Stephen Hawking.Callum D. Scott - 2012 - South African Journal of Philosophy 31 (2):385-404.
    In his 2010 work, The Grand Design, Stephen Hawking, argues that ‘… philosophy is dead’. While not a Philosopher, Hawking provides strong argument for his thesis, principally that philosophers have not taken science sufficiently seriously and so Philosophy is no longer relevant to knowledge claims. In this paper, Hawking’s claim is appraised and critiqued, becoming a meta-philosophical discussion. It is argued that Philosophy is dead, in some sense, due to particular philosophers having embarked on an intellectual path no longer in (...)

    Rewriting Aquinas’ animal ethics: the primacy of reason in the determination of moral status.Callum David Scott & Yolandi Marié Coetser - 2015 - South African Journal of Philosophy 34 (3):289-303.
    Arguing in support of Aristotle, Aquinas conceptualised the cognitive functioning of the human as exceeding that of other animals. In its base form, the Thomistic position asserts that the intellective functioning of the human animal is superior to the instinctual operation of the non-human animal. For Aquinas, it is the intellect that determines the enactment of the human will. Thus, if a non-human animal is devoid of intellect, no willing of any action is possible. Consequently, an action of a non-human (...)

    The decolonial Aquinas? Discerning epistemic worth for Aquinas in the decolonial academy.Callum David Scott - 2019 - South African Journal of Philosophy 38 (1):40-54.
    As the ideological constructor of the destruction of colonised peoples and knowledge, Western philosophy must bear its burden for complicity. Decoloniality is amid the discourses of critique contra modernity and its denigration of the colonised. In the South African academy, for instance, much support has been validly rendered to decoloniality, consequently those employing “Western” frameworks should be challenged to constant re-evaluation. Here, the virtues and vices of decoloniality will not be considered. Rather a discernment will be undertaken of the “epistemic (...)

    Functional interpretations of feasibly constructive arithmetic.Stephen Cook & Alasdair Urquhart - 1993 - Annals of Pure and Applied Logic 63 (2):103-200.
    A notion of feasible function of finite type based on the typed lambda calculus is introduced which generalizes the familiar type 1 polynomial-time functions. An intuitionistic theory IPVω is presented for reasoning about these functions. Interpretations for IPVω are developed both in the style of Kreisel's modified realizability and Gödel's Dialectica interpretation. Applications include alternative proofs for Buss's results concerning the classical first-order system S12 and its intuitionistic counterpart IS12 as well as proofs of some of Buss's conjectures concerning IS12, (...)

    Synonymous logics.Francis Jeffry Pelletier & Alasdair Urquhart - 2003 - Journal of Philosophical Logic 32 (3):259-285.
    This paper discusses the general problem of translation functions between logics, given in axiomatic form, and in particular, the problem of determining when two such logics are "synonymous" or "translationally equivalent." We discuss a proposed formal definition of translational equivalence, show why it is reasonable, and also discuss its relation to earlier definitions in the literature. We also give a simple criterion for showing that two modal logics are not translationally equivalent, and apply this to well-known examples. Some philosophical morals (...)

    Are essay mills committing fraud? A further analysis of their behaviours vs the 2006 fraud act (UK).Callum Reid-Hutchings & Michael J. Draper - 2019 - International Journal for Educational Integrity 15 (1).
    Many strategies have been proposed to address the supply of bespoke essays and other assignments by companies often described as ‘Essay Mills’ with the act of supply and use being invariably described as ‘contract cheating’. These proposals increasingly refer to the law as a solution in common with other action. In this article, the lead author revisits work undertaken in 2016 as a result of recent legal and extra-legal developments to assess whether the UK Fraud Act (2006) might now be (...)

    Matrix identities and the pigeonhole principle.Michael Soltys & Alasdair Urquhart - 2004 - Archive for Mathematical Logic 43 (3):351-357.
    We show that short bounded-depth Frege proofs of matrix identities, such as PQ=I⊃QP=I (over the field of two elements), imply short bounded-depth Frege proofs of the pigeonhole principle. Since the latter principle is known to require exponential-size bounded-depth Frege proofs, it follows that the propositional version of the matrix principle also requires bounded-depth Frege proofs of exponential size.

    Michael Kremer defines fixed-point logics of truth based on Saul Kripke’s fixed point semantics for languages expressing their own truth concepts. Kremer axiomatizes the strong Kleene fixed-point logic of truth and the weak Kleene fixed-point logic of truth, but leaves the axiomatizability question open for the supervaluation fixed-point logic of truth and its variants. We show that the principal supervaluation fixed point logic of truth, when thought of as consequence relation, is highly complex: it is not even analytic. We also (...)

    Mathematics and philosophy have historically enjoyed a mutually beneficial and productive relationship, as a brief review of the work of mathematician–philosophers such as Descartes, Leibniz, Bolzano, Dedekind, Frege, Brouwer, Hilbert, Gödel, and Weyl easily confirms. In the last century, it was especially mathematical logic and research in the foundations of mathematics which, to a significant extent, have been driven by philosophical motivations and carried out by technically minded philosophers. Mathematical logic continues to play an important role in contemporary philosophy, and (...)

    Distributive lattices with a dual homomorphic operation.Alasdair Urquhart - 1979 - Studia Logica 38 (2):201 - 209.
    The lattices of the title generalize the concept of a De Morgan lattice. A representation in terms of ordered topological spaces is described. This topological duality is applied to describe homomorphisms, congruences, and subdirectly irreducible and free lattices in the category. In addition, certain equational subclasses are described in detail.
