Pure mathematical truths are commonly thought to be metaphysically necessary. Assuming the truth of pure mathematics as currently pursued, and presupposing that set theory serves as a foundation of pure mathematics, this article aims to provide a metaphysical explanation of why pure mathematics is metaphysically necessary.

In this paper, I argue that unification is neither necessary nor sufficient for explanation. Focusing on the versions of the unificationist theory of explanation of Kitcher and of Schurz and Lambert, I establish three theses. First, Kitcher’s criterion of unification is vitiated by the fact that it entails that every proposition can be explained by itself, a flaw that it is unable to overcome. Second, because neither Kitcher’s theory nor that of Schurz and Lambert can solve the problems of (...) asymmetry and accidental generalizations, it follows that unification is not sufficient to ground explanation. Third, some good explanations are disunifying, which entails that unification is not necessary for explanation either. (shrink)

Background Randomized controlled trials are central to generating knowledge about effectiveness of interventions as well as risk, protective and prognostic factors related to diseases in emergency newborn care. Whether prospective participants understand the purpose of research, and what they perceive as the influence of the context on their understanding of the informed consent process for RCTs in emergency obstetric and newborn care are not well documented. Methods Conceptual review. Discussion Research is necessary to identify how the illnesses may be (...) prevented, to explore the causes, and to investigate what medications could be used to manage such illness. Voluntary informed consent requires that prospective participants understand the disclose information about the research, and use this to make autonomous informed decision about participation, in line with their preferences and values. Yet the emergency context affects how information may be disclosed to prospective research participants, how much participants may comprehend, and how participants may express their voluntary decision to participate, all of which pose a threat to the validity of the informed consent. I challenge the claim that the ‘understanding’ of research is always necessary for ethical informed consent for research during emergency care. I argue for reconceptualization of the value of understanding, through recognition of other values that may be equally important. I then present a reflective perspective that frames moral reflection about autonomy, beneficence and justice in research in emergency research. Conclusion While participant ‘understanding’ of research is important, it is neither necessary nor sufficient for a valid informed consent, and may compete with other values with which it needs to be considered.

Militairy technology is developing at a rapid pace and we are seeing a growing number of weapons with increasing levels of autonomy being developed and deployed. This raises various legal, ethical, and security concerns. The absence of clear international rules setting limits and governing the use of autonomous weapons is extremely concerning. There is an urgent need for the international community to work together towards a treaty not only to safeguard ethical and legal norms, but also for our shared security. (...) This article explains why a treaty on autonomous weapons is needed and achievable. It goes into what a treaty could consist of to establish an international norm and set rules and limits on autonomy in weapon systems. (shrink)

In standard modal logic, □ ≡ ∼◊ ∼ and ◊ ≡ ∼□∼. I will, first, examine why in tense-logic, Arthur Prior thinks that ∼ ◊ ∼ is weaker than □ and ∼ □ ∼ is weaker than ◊. I will, then, examine whether there are similar motivations in modal logic to take ∼ ◊ ∼ to be weaker than □ and ∼ □ ∼ to be weaker than ◊. The upshot will be that, just as certain metaphysical views within the (...) philosophy of time motivate one to deny the standard tense equivalences, certain metaphysical views within the metaphysics of modality motivate one to deny the standard modal equivalences.

In the ethical texts, Aristotle claims that all instances of choice (prohairesis) must be preceded by deliberation, but it is not clear why he believes this. This paper offers an explanation of that commitment, drawing heavily from the De Anima and showing that the account emerging from there complements that of the ethical texts. The view is that the deliberative faculty has the capacity to manipulate reasons combinatorially, while the perceptual/desiderative faculty does not, and choice requires the combinatorial manipulation of (...) reasons.

Iris Marion Young presents a social connection model on which those, and only those, who participate in structural processes that produce injustice have a forward-looking responsibility to redress the resulting injustice by challenging the structures that produce it. In Young's view, this is an all-things-considered, albeit discretionary, responsibility. I argue that participation in a structural process that produces injustice is neither necessary nor sufficient for having political responsibilities, and that therefore the social connection model must be rejected. A subtler (...) model is needed, one that depicts participation in a structural process that produces injustice as sufficient for having pro tanto forward-looking responsibilities to redress the process, unless the participating agent satisfies certain excusing conditions. I suggest the intuitive force of the thought that mere participation gives us political responsibilities can be explained by more fundamental considerations. Hastily, we might conclude that all participants have political responsibilities simply because most of them satisfy at least one of the following conditions: they cause injustice to continue, they are morally responsible for injustice, they benefit from injustice, they have communal ties with the victims of injustice, or they have the capacity to redress injustice.

In ‘Are Citizenship Tests Necessarily Illiberal?’, Michael Blake argues that difficult citizenship tests are not necessarily illiberal, so long as they test for the right things. In this paper, I argue that Blake’s attempt to square citizenship tests with liberalism fails. Blake underestimates the burdens citizenship tests impose on immigrants, ignoring in particular the egalitarian claims immigrants have on equal social membership. Moreover, Blake’s positive justification of citizenship tests – that they help justify immigrants’ coercive voting power – both neglects (...) the fact that such tests are coercively imposed on immigrants and that the citizenship test Blake envisions does little to help ensure immigrants’ votes are legitimate. Citizenship tests thus aren’t, even in principle, a way of protecting citizens from unjustified coercive power. They are, even under favourable circumstances, an illiberal way of obstructing immigrants’ quest for social equality. (shrink)

This paper argues that the principle of necessary identity (f)(g)(f=g then necessarily f=g) cannot be maintained, At least in second order form. A paradox based upon scientific definitional practice is introduced to demonstrate this. A non-Fregean reading of standard contingent identity semantics is provided to explain how such 'definition breaking' works.

While humans have made enormous progress in the exploration and exploitation of Earth, exploration of outer space remains beyond current human capabilities. The principal challenges lie in current space technology and engineering which includes the protection of astronauts from the hazards of working and living in the space environment. These challenges may lead to a paradoxical situation where progress in space technology and the ability to ensure acceptable risk/benefit for human space exploration becomes dissociated and the rate of scientific discovery (...) declines. In this paper, we discuss the predominant challenges of the space environment for human health and argue that development and deployment of a human enhancement policy, initially confined to astronauts – for the purpose of future human space programmes is a rational solution to these challenges.

I defend the thesis that psychological states can be literally ascribed only to living creatures and not to nonliving machines, such as sophisticated robots. Defenders of machine consciousness do not sufficiently appreciate the importance of the biological nature of a subject for the psychological significance of its behavior. Simulations of a computer-controlled, nonliving autonomous robot cannot carry the same psychological meaning as animate behavior. Being a living creature is an essential link between genuinely expressive behavior and justified psychological ascriptions.

In this short article Tibor Machan questions whether those who reject Western liberalism yet call for a return to morality are being entirely consistent.

This paper argues that according to Aquinas, the appetites require habits in order to function in order to complete the natural intentional structure of the appetite. In order to move the agent to act, the appetites must incline towards some specific good identified through sensory perception or reason. But human appetites, in contrast to the passions of non-rational animals, do not spontaneously incline towards particular objects. They must be shaped through processes of rationally governed formation, including in the case of (...) the will processes of practical induction, in order to incline towards specific objects in the needed way.

Die forensische Psychiatrie und insbesondere ihr klinischer Bereich, der Maßregelvollzug, sind im Hinblick auf Forschung noch weitgehend eine terra incognita. Steigende Unterbringungszahlen und Gesetzesreformen belasten die klinische Arbeit des Maßregelvollzugs. Zugleich hat der Fall Mollath Fragen an der Zuverlässigkeit forensisch-psychiatrischer Prognosen aufgeworfen. Gerade im zentralen Arbeitsbereich der Kriminal- und Gefährlichkeitsprognose fehlen epidemiologische und Verlaufsdaten. Auch zur Effizienz der Therapieprogramme und der Frage, welche Maßnahmen letztlich zu einer Verbesserung der Prognose bei Maßregelvollzugspatienten führen, gibt es keine einheitlichen Daten. Vor dem Hintergrund (...) des Doppelmandates der Besserung und Sicherung und des Anspruchs der Gesellschaft, vor gefährlichen, psychisch kranken Straftätern geschützt zu werden, ist es sowohl fachlich wie ethisch geboten, über die Frage der Effizienz der forensisch-psychiatrischen Arbeit zu forschen. Hiermit will sich die vorliegende Arbeit auseinandersetzen und die fachlichen sowie ethischen Aspekte diskutieren. Ansätze aus der Sozialethik können hier Argumente für eine ethisch verantwortbare Forschung auf diesem Gebiet liefern. (shrink)

Although the target article is groundbreaking and creatively conceived, there are troubling questions regarding its methodology and conclusions. The sample in the authors' study was drawn from a popular magazine's lists; there is no recognition of the fact that most faculty are now off the tenure track; and comparisons are made with the British system with no supporting data.

Economic theory reduces the concept of rationality to internal consistency. As far as beliefs are concerned, rationality is equated with having a prior belief over a “Grand State Space”, describing all possible sources of uncertainties. We argue that this notion is too weak in some senses and too strong in others. It is too weak because it does not distinguish between rational and irrational beliefs. Relatedly, the Bayesian approach, when applied to the Grand State Space, is inherently incapable of describing (...) the formation of prior beliefs. On the other hand, this notion of rationality is too strong because there are many situations in which there is not sufficient information for an individual to generate a Bayesian prior. It follows that the Bayesian approach is neither sufficient not necessary for the rationality of beliefs. (shrink)

In a recent issue of this journal, Jorn Sonderholm presents two main criticisms of my 2008 case for a diachronic view of base property exemplification in metaethics. This essay contends that neither of Sonderholm’s criticisms hit their mark, and that there are additional reasons to adopt a diachronic view of base property exemplification. Thus, the case for a diachronic view of base property exemplification in metaethics is stronger than previously thought.

The existence of "undermining futures" appears to show that a contradiction can be deduced from the conjunction of Humean supervenience (HS) about chance and the Principal Principle. A number of strategies for rescuing HS from this problem have been proposed recently. In this paper, a novel way of defending HS from the threat is presented, and it is argued that this defense has advantages not shared by others. In particular, it requires no revisionism about chance, and it is equally available (...) to defenders of HS who hold HS to be necessary and those who hold it to be contingent. (shrink)

What is it for an object to be a physical object? Here I provisionally take up the idea that spatial extension is at least a necessary condition for being a physical object, whether or not it is also sufficient. I then argue for the following conditional proposition: if spatial extension is a necessary condition for being a physical object, then metaphysical naturalism is false. Given that all religious systems affirm the falsity of metaphysical naturalism, this conditional carries obvious (...) significance for philosophy of religion. And if it holds, two possible consequences ensue: for those committed to the idea that spatial extension is a necessary condition for being a physical object, a new disproof of metaphysical naturalism results. By contrast, for those committed to metaphysical naturalism, a new disproof of any extension-based account of the physical results. Either way, we obtain a significant conclusion. (shrink)

The chapter first formulates the problems of information and analyzes why they are hard to solve. Then it critically reviews two classes of prevailing theories in information studies arguing that they cannot attain success because the assumptions behind them are too limited. In recent years, some semioticians have rediscovered the theory of information developed by Peirce. Deeply embodied in semiotics, the theory treats information as the communication of form in semiosis, which should be interpreted in terms of triadic relation in (...) the semiotic relational process between representamen, object and interpretant. As a contemporary development of Peircean theory, cybersemiotics further constructs a conceptual framework through integrating it with Luhmann’s social system theory. In particular, the transdisciplinary framework cybersemiotics shows a promising way to explain superficially incompatible aspects of information with the aid of the principle of complementarity.

Necessity can be ascribed not only to propositions, but also to feelings. In the Critique of Judgment (KdU), Immanuel Kant argues that a feeling of beauty is the necessary satisfaction instantiated by the ‘free play’ of the cognitive faculties, which provides the grounds for a judgment of taste (KdU 5:196, 217-19). In contradistinction to the theoretical necessity of the Critique of Pure Reason and the moral necessity of the Critique of Practical Reason, the necessity assigned to a judgment of (...) taste is exemplary necessity (KdU 5:237). Necessity can also be assigned by employing the de re/de dicto distinction, namely, by ascribing entailments of what must necessarily hold to either a thing (de re) or to a proposition (de dicto). Although Kant does not use the distinction in any of the three Critiques, this omission has not prevented Kant scholars from applying the distinction in their analyses of the first two Critiques. In this paper, I examine the role that modality plays in Kant’s third Critique and I attempt to bring the de re/de dicto distinction to bear on Kant’s famous aesthetic theory. Ultimately, I perform a retrospective classification of the modality of taste by arguing that because a judgment of taste is not a statement about an objective fact, a judgment of ‘x is beautiful’ can only be read as de dicto necessary.

The paper treats Avicenna’s ’metaphysical’ argument for the existence of God and the modal metaphysics that underpins it. Earlier analyses of modalities attempted to reduce necessity, possibility and impossibility to nonmodal elements, which was done most commonly by appealing to a temporal frequency model of modalities. In contrast, Avicenna believed that modalities were an inherent feature of existence, and so just as there is nothing more basic than existence, so likewise there is nothing more basic in term of which modalities (...) can be explained. The article concludes by considering how Avicenna’s modal metaphysics in turn provides him the means to show the absolute and nonconditional necessity of God, as opposed to the conditional necessity of earlier ’physical’ arguments.

The paper asks about the difficulty of reading Schelling's work today given the historical biases that dominate contemporary philosophical inquiry. But if we cannot succeed as the readers Schelling himself appears to be looking for, this does not already have to mean that his work cannot speak to our time. Such a possibility, however, presupposes that we consider Schelling's work as it is inseparably connected to a critique of the modern project and as it points thereby to the monstrous discord (...) that defines human philosophical discourse as such. In particular, the paper considers the Kantian opposition between faith and knowledge and claims that this opposition itself appears to establish a kind of limit for philosophical inquiry today. In this context, some reflections are offered on the history of European nihilism and the death of God. The paper concludes by giving several indications of how Schelling's thought promises to subvert this opposition and this limit. (shrink)

A dazzling blend of business vision, history, social psychology, and economics, The Support Economy starts with a compelling premise: People have changed more than the corporations upon which their well-being depends. In the chasm that now separates the new individuals from the old organizations is the opportunity to forge a capitalism suited to our times and so unleash a vast new potential for wealth creation. In recent years, many books have offered fixes for this crisis, but they have dealt only (...) with its symptoms. The Support Economy is the first book to critically examine its cause: Managerial capitalism has outlived the society it was once designed to serve. It successfully achieved the efficient production of goods and services, but today's individuals want more. They want to take their lives into their own hands and are ready to pay for the support and advocacy necessary to fulfill that yearning. The next leap forward in wealth creation depends upon developing a new capitalism that speaks to the needs of people today. The Support Economy will be the next "must read" big think book. It speaks to every business and technology leader, as well as every reader interested in the future of the economy and society. (shrink)

In this paper I argue that many of the core phenomenological insights, including the emphasis on direct perception, are a necessary but not sufficient condition for an adequate account of inter-subjectivity today. I take it that an adequate account of inter-subjectivity must involve substantial interaction with empirical studies, notwithstanding the putative methodological differences between phenomenological description and scientific explanation. As such, I will need to explicate what kind of phenomenology survives, and indeed, thrives, in a milieu that necessitates engagement (...) with the relevant sciences, albeit not necessarily deference to them. -/- There will be two central aims to this paper: 1. to defend the centrality and vitality of phenomenological treatments of inter-subjectivity via a consideration of some remarks in Sartre - which I do think possess a non-trivial unity amongst the various interlocutors - and the manner in which they in fact serve to provide the basis for a better explanation of an array of empirical data than existing inferentialist or mindreading accounts of social cognition (notably Theory Theory, Simulation Theory, and hybrid versions); 2. to offer the methodological resources for renewing phenomenology in a manner that acknowledges ostensibly non-phenomenological moments in theory production - which involve explanation, inference to the best explanation, etc. - but does not abandon phenomenology for all that, allowing it to be simply absorbed into empirical explanation or other forms of philosophical analysis without remainder.

Contemporary debates on decolonising knowledge production, inclusive of research on Africa, are crucial and challenge researchers to reflect on the legacies of colonial power relations that continue to permeate the production of knowledge about the continent, its peoples, and societies. Yet these are not new debates. Sixty years ago, Ghana’s first president and pan-Africanist leader, Dr Kwame Nkrumah, highlighted the importance of Africa-centred knowledge. Similarly, in the 1980s, Claude Ake advocated for endogenous knowledge production on Africa. But progress has been (...) slow at best, indicated by the enduring predominance of non-African writers on African issues within leading scholarly journals. Thus, we examine why decolonisation of knowledge production remains so necessary and what can be done within the context of scholarly research in the humanities and social sciences. These questions are addressed at two levels, one more practical and one more reflective . At both levels, issues of power inequalities and injustice are critical. At the practical level, the asymmetrical power relations between scholars in the Global North and South are highlighted. At a deeper level, the critiques of contemporary African authors are outlined, all contesting the ongoing coloniality and epistemic injustices that affect knowledge production on Africa, and calling for a more fundamental reorientation of ontological, epistemological, and methodological approaches in order to decolonise knowledge production.

Recent years have seen a concerted and systematic move towards a school-led system of initial teacher training in England. The role of universities, and particularly their part in engaging new teachers with educational theory, has been radically challenged. Only around half of new entrants to the profession now follow university-based training routes. These seismic changes to teacher education have been driven through with a minimum of formal consultation or public debate. In this urgent and compelling pamphlet, Janet Orchard and Christopher (...) Winch argue for a conception of teachers as professionals who require a deep understanding of the conceptual, empirical and normative dimensions of educational practice. They explain why university education departments are better placed than schools to help beginning teachers acquire that understanding. And they propose a significant expansion of initial teacher education, with full licensure contingent on completion of both a preliminary teaching qualification and a higher grade apprenticeship in the first two years of employment. Teachers need educational theory because they must understand what they are doing and why they are doing it, and must be able to think intelligently about how to do it better. At present, universities have the capacity and the expertise to meet this need. But they may not have it for much longer if the shift to school-based teacher education continues unabated. (shrink)

This paper aims at emphasizing the relevance of scrutinizing the link between Heidegger’s theory of Being and his Nazi commitment. Significant investigations of such a link, beginning with that of Victor Farias, have challenged the „official” view that Heidegger’s theory of Being is politically neutral. That this theory could not have been deprived of political intentions is proven by Heidegger’s own view on philosophy as a search that stems from life and ends in life, namely as a Dasein’s way of (...) life. Since fundamental ontology (theory) and existential analytic (practice) cannot be separated, exploring the relationship between them is even more necessary. (shrink)

Why a hermeneutical philosophy of the natural sciences? It is necessary to address the philosophic crisis of realism vs relativism in the natural sciences. This crisis is seen as a part of the cultural crisis that Husserl and Heidegger identified and attributed to the hegemonic role of theoretical and calculative thought in Western societies. The role of theory is addressed using the hermeneutical circle to probe the origin of theoretic meaning in scientific cultural praxes. This is studied in Galileo's (...) discovery of the phases of Venus; the practice of measurement; the different theories and practices of space perception; the historicality and temporality of scientific research communities which ground paradigm change; and the process of discovery. The paper draws particularly from the work of Heidegger. Though envisaging all science and scholarship, the highlighted theme is research in the natural sciences. (shrink)
