This work-in-progress paper consists of four points which relate to the foundations and physical realization of quantum computing. The first point is that the qubit cannot be taken as the basic unit for quantum computing, because not every superposition of bit-strings of length n can be factored into a string of n-qubits. The second point is that the “No-cloning” theorem does not apply to the copying of one quantum register into another register, because the mathematical representation of this copying is (...) the identity operator, which is manifestly linear. The third point is that quantum parallelism is not destroyed only by environmental decoherence. There are two other forms of decoherence, which we call measurement decoherence and internal decoherence, that can also destroy quantum parallelism. The fourth point is that processing the contents of a quantum register “one qubit at a time” destroys entanglement. (shrink)

Every day we seem to make and act upon all kinds of free choices: some trivial, others so consequential that they change the course of one's life, or even the course of history. But are these choices really free, or are we compelled to act the way we do by factors beyond our control? Is the feeling that we could have made different decisions just an illusion? And if our choices are not free, is it legitimate to hold people morally (...) responsible for their actions? Pink looks at the fundamental philosophical question of free will, Engaging in discussion of the claim: 'If our actions are causally determined by events beyond our control, that means that we can never act freely, and so can never be held responsible for our actions.

This 1996 book presents an alternative theory of the will - of our capacity for decision making. The book argues that taking a decision to act is something we do, and do freely - as much an action as the actions which our decisions explain - and that our freedom of action depends on this capacity for free decision-making. But decision-making is no ordinary action. Decisions to act also have a special executive function, that of ensuring the rationality of the (...) further actions which they explain. This executive function makes decision-making an action importantly unlike any other, with its own distinctive rationality. Pink's highly persuasive study uses this theory of the will to provide accounts of freedom, action and rational choice. The author argues that, in a tradition that runs from Hobbes to Davidson and Frankfurt, Anglo-American philosophy has misrepresented the common-sense psychology of our freedom and action - a psychology which this book now presents and defends.

Abstract Freedom in the sense of free will is a multiway power to do any one of a number of things, leaving it up to us which one of a range of options by way of action we perform. What are the ethical implications of our possession of such a power? The paper examines the pre-Hobbesian scholastic view of writers such as Peter Lombard and Francisco Suárez: freedom as a multiway power is linked to the right to liberty understood as (...) a right to exercise that power, and to liberation as a desirable goal involving the perfection of that power. Freedom as a power, liberty as a right, and liberation as a desirable goal, are all linked within this scholastic view to a distinctive theory of law as constituting, in its primary form of natural law, the normative recognition of human freedom. Hobbes's denial of the very existence of freedom as a power led him to a radical revision both of the theory of law and of the relation of law to liberty. Law and liberty were no longer harmonious phenomena, but were left in essential conflict. One legacy of Hobbes is the attempt to base a theory of law and liberty not on freedom as a multiway power, but on rationality. Instead of an ethics of freedom, we have an ethics of reason as involving autonomy. The paper expresses some scepticism about the prospects for such an appeal to reason as a replacement for multiway freedom. (shrink)

Our moral responsibility for our actions seems to depend on our possession of a power to determine for ourselves what actions we perform - a power of self-determination. What kind of power is this? The paper discusses what power in general might involve, what differing kinds of power there might be, and the nature of self-determination in particular. A central question is whether this power on which our moral responsibility depends is by its nature a two-way power, involving a power (...) over alternatives or a freedom to do otherwise. Criticism is made of various attempts to understand self-determination in one-way terms, whether as a capacity for rationality (McDowell) or as a form of voluntariness (Frankfurt). It is argued in particular that Frankfurt's arguments to show that moral responsibility does not depend on a freedom to do otherwise beg the question against his opponents. (shrink)

Thomas Pink; XIII*—Reason and Agency, Proceedings of the Aristotelian Society, Volume 97, Issue 1, 1 June 1997, Pages 263–280, https://doi.org/10.1111/1467-9264.

Do we have control of how we act, and does it matter to morality whether we do? Thomas Pink examines this free will problem by arguing that what matters to morality is not in fact the freedom to do otherwise, but something more primitive, a basic capacity or power to determine for ourselves what we do.

The paper examines the place of power in the action theories of Francisco Suarez and Thomas Hobbes. Power is the capacity to produce or determine outcomes. Two cases of power are examined. The first is freedom or the power of agents to determine for themselves what they do. The second is motivation, which involves a power to which agents are subject, and by which they are moved to pursue a goal. Suarez, in the Metaphysical Disputations, uses Aristotelian causation to model (...) these two forms of power. Freedom is efficient causation, but in a special form that I explain as involving something that ordinary causation does not – the contingent determination of outcomes. Motivating power is final causation, which Suarez characterizes as the power of a goal or end to move us to attain it through its goodness or desirability. Suarez regards these two forms of power as consistent – we can be moved by the goodness of a goal freely to determine for ourselves that we act in order to attain it. Hobbes denied the existence of all forms of power beyond ordinary causation, the power of one motion in matter to determine another. So he denied the very existence both of freedom and of any form of motivating power beyond the ordinary causal power of desires as materially based psychological states to produce actions. The goodness itself of a goal never moves us, whether to desire the goal in the first place or to act in order to attain it. The paper examines Hobbes’s arguments and their consequence – establishing the foundations for Hume’s scepticism about practical reason. (shrink)

Trust and trustworthiness are central concepts in contemporary discussions about the ethics of and qualities associated with artificial intelligence (AI) and the relationships between people, organisations and AI. In this article we develop an interdisciplinary approach, using socio-technical software engineering and design anthropological approaches, to investigate how trust and trustworthiness concepts are articulated and performed by AI software practitioners. We examine how trust and trustworthiness are defined in relation to AI across these disciplines, and investigate how AI, trust and trustworthiness (...) are conceptualised and experienced through an ethnographic study of the work practices of nine practitioners in the software industry. We present key implications of our findings for the generation of trust and trustworthiness and for the training and education of future software practitioners. (shrink)

What is the will? And what is its relation to human action? Throughout history, philosophers have been fascinated by the idea of 'the will': the source of the drive that motivates human beings to act. However, there has never been a clear consensus as to what the will is and how it relates to human action. Some philosophers have taken the will to be based firmly in reason and rational choice, and some have seen it as purely self-determined. Others have (...) replaced the idea of the human will with a more general drive uniting humans and the rest of nature, living and non-living. This collection of nine specially commissioned papers trace the formulation and treatment of the problem of the will from ancient philosophy through the scholastic theologians of the Middle Ages, to modern philosophy, and right up to contemporary theories. Philosophers discussed include Plato, Aristotle, Augustine, Aquinas, Bonaventure, Hobbes, Kant, Schopenhauer and Nietzsche. (shrink)

Moral obligation is a demand of reason—a demanding kind of rational justification. How to understand this rational demand? Much recent philosophy, as in the work of Scanlon, takes obligatoriness to be a reason-giving feature of an action. But the paper argues that moral obligatoriness should instead be understood as a mode of justificatory support—as a distinctive justificatory force of demand. The paper argues that this second model of obligation, the Force model, was central to the natural law tradition in ethics, (...) is truer to everyday intuition about obligation, and also changes our understanding of the problem of moral rationality. A new account is given of why it might be irrational to breach moral obligations. The Force model also sheds new light on moral responsibility, our responsibility for meeting moral obligations. Moral obligation is a standard of reason; but moral responsibility is shown to involve far more than ordinary rational appraisability, precisely because moral obligation involves a distinctive justificatory force of demand—one which specifically governs how we act. Key Words: blame • moral responsibility • natural law • normativity • obligation • reason. (shrink)

Some key aspects of contemporary epistemology deserve to be challenged, and _How to Know_ does just that. This book argues that several long-standing presumptions at the heart of the standard analytic conception of knowledge are false, and defends an alternative, a practicalist conception of knowledge. Presents a philosophically original conception of knowledge, at odds with some central tenets of analytic epistemology Offers a dissolution of epistemology’s infamous Gettier problem — explaining why the supposed problem was never really a problem in (...) the first place. Defends an unorthodox conception of the relationship between knowledge-that and knowledge-how, understanding knowledge-that as a _kind_ of knowledge-how. (shrink)

What is knowledge? How hard is it for a person to have knowledge? Good Knowledge, Bad Knowledge confronts contemporary philosophical attempts to answer those classic questions, offering a theory of knowledge that is unique in conceiving of knowledge in a non-absolutist way.

Does Suárez's view that political authority rests on consent or agreement make him a herald of modern contractarian theories of the state, as Quentin Skinner has argued? Or does Suárez have a fundamentally different conception of political authority? The paper will argue the latter. Modern theories of coercive authority view it as a product of human artifice, with the functions both of facilitating cooperation through coordination and of threatening sanction to contain ill will. For Suárez, by contrast, coercive authority is (...) divinely instituted, in various ways, and has the further function of enabling the proper human exercise of or response to forms of power that are not ordinary causation. In particular coercive authority acts as a channel and teacher for forms of power that are normative – that constitute various forms of the power of truth or of goodness. Coercive authority exists at the natural level as the authority of the state, channeling the power of natural reason in relation to the good of a community, and at the supernatural level as the authority of the Church channeling the power of grace. Central to the functioning of authority at both the natural and supernatural levels is the coercive direction of belief. This is a conception of authority that is very alien to modern political theory – thanks, in large part, to the influence of Hobbes. (shrink)

The paper examines the natural law tradition in ethics and legal theory. This tradition is shown to address two questions. The first question is to do with the nature of law, and the kind of human capacity that is subject to legal direction. Is law directive of the voluntary—of what is subject to the will, or what can be done or refrained from on the basis of a decision so to do? Or is law directive of some other kind of (...) capacity? The second question is about the nature of ethical normativity, and the relation within normativity of its directive and appraisive aspects. Is direction primary, and appraisal to be explained in terms of a theory of direction; or must a theory of ethical direction be based on a theory of ethical appraisal? Both issues are introduced by reference to Hume's ethical theory, which raises them in a particularly sharp form. The natural law tradition, in the form it reached by the early modern period, is shown to combine giving a primacy to the appraisive in normative theory, with, in legal theory, a detachment of law from any exclusive tie to the direction of the voluntary. At the heart of the theory of natural law is the idea of law as a distinctive form of normativity directive of a capacity not for voluntariness, but for self-determination. Combined with a view of the state not just as a coordinative authority but as a coercive teacher, this led to a distinctive and highly controversial view of the scope of positive law. The paper ends with Hobbes's sharp opposition to this view of positive law—an opposition that focused, in particular, on the coercive legal direction of belief. (shrink)

This contribution to a symposium on quietism concerns what is known as the Quietist period of Quakerism in the eighteenth century. Dandelion addresses the key question of conflict between the quietist commitment of the Quaker faithful and the commitment of many among them to abolitionism and other pressing social causes. He reviews the scholarship on this issue, noting the recent tendency to look for mystical aspects to the social commitment of Quakers. Instead, however, he argues that the culture of Friends (...) during this period became self-enclosed to a remarkable degree, permitting some of the members to move about extramurally, as required by conscience, then return to their essentially quietist world.

As has been often descried, the well-being and integration of refugees, asylum seekers and immigrants mutually influence each other. Therefore, OMEGA Health Care Center is carrying through programs which at the same time further integration on the level of individuals and help prevent or address psychological, social and medical problems. Women and minors are the main target groups of these programs. Aside form giving adolescents concrete support—e.g. in their schoolwork—most of our youth programs focus on active work toward integration. This (...) we understand as supporting real contact between individuals of different cultures. Currently, OMEGA is conducting outreach activities in refugee shelters and schools. In afternoon activities minors have the opportunity to join a music group, to participate in a school support program and to attend computer courses. One goal of our work it to include marginalized youth in all these groups and actively support their social integration in the mainstream society. Finally, the results of an evaluation of our music group and possible interventions for group leaders are discussed. (shrink)

Hume thought that if actions were not determined causally by prior events they could depend on nothing more than chance. But we seem to think that even actions undetermined by prior events need not happen by mere chance. They could be still determined by their agents; they could therefore be free. What does this belief in freedom involve? Is it simply the theory that substances, in the form of agents, can be causes, and not just events? The chapter argues that (...) this is not so. Our conception of freedom is of a power radically unlike ordinary causation, not simply in respect of the bearer of the power, but in the way that the power determines outcomes. A cause determines an outcome only when its power excludes alternatives. But freedom is a power that far from excluding alternatives, makes them available. The chapter explores this difference between the two kinds of power, and the implications of Hume’s failure to distinguish them. (shrink)

Life history theory predicts that exposure to high mortality in early childhood leads to faster and riskier reproductive strategies. Individuals who grew up in a high mortality regime will not overly wait until they find a suitable partner and form a stable union because premature death would prevent them from reproducing. Cox proportional hazard models were used to determine whether women who experienced sibling death during early childhood (0–5 years) reproduced earlier and were at an increased risk of giving birth (...) to an illegitimate child, with illegitimacy serving as a proxy for risky sexual behavior. Furthermore, we investigate whether giving birth out of wedlock is influenced by individual mortality experience or by more promiscuous sexual behavior that is clustered in certain families. Models are fitted on pedigree data from the eighteenth- and nineteenth-century Krummhörn population in Germany. The results show a relationship between sibling death in early childhood and the risk of reproducing out of wedlock, and reproductive timing. The risk of giving birth out of wedlock is linked to individual mortality experience rather than to family-level effects. In contrast, adjustments in connubial reproductive timing are influenced more by family-level effects than by individual mortality experience. (shrink)

In this article we outline two different ways of ‘seeing’ autonomous driving (AD) cars. The first corresponds with the technological innovation narrative, published in online industry, policy, business and other news contexts, that pitches AD cars as the solution to societal problems, and urges users to trust and accept them so that such benefits can be accrued. The second is a narrative of everyday improvisation, which was visualized through our video ethnography and participant mapping exercises. Our research, undertaken in Sweden, (...) involved possible future everyday users of AD cars. We argue for a research and intervention agenda that examines how the visual narration of how AD cars might participate in human futures, could be shifted to create new modes of trust and reassurance for publics.

Hobbes’s views on free will and action were radically revisionary of a well-established scholastic theory of the ethical significance of freedom and of freedom’s relation to law. At the heart of this scholastic theory was an account of freedom as a multiway power to determine alternatives and of human action as a distinctively practical mode of exercising reason. The chapter explains this theory as developed by Suarez and, following Suarez, by Bramhall, and examines Hobbes’s attack on the theory’s basis—the theory (...) of freedom as a metaphysical power and of action as a distinctively practical mode of exercising reason.

It is often thought that as human agents we have a power to determine our actions for ourselves. And a natural conception of this power is as freedom – a power over alternatives so that we can determine for ourselves which of a variety of possible actions we perform. But what is the real content of this conception of freedom, and need self-determination take this particular form? I examine the possible forms self-determination might take, and the various ways freedom as (...) a power over alternatives might be constituted. I argue that though ordinary ethical thought, and especially moral blame, may be committed to our possession of some capacity for self-determination, the precise nature of this power is probably ethically underdetermined – though conceptions of the nature of the power that come from outside ethics may then have important implications for ethics.

Michael Dummett and Dag Prawitz have argued that a constructivist theory of meaning depends on explicating the meaning of logical constants in terms of the theory of valid inference, imposing a constraint of harmony on acceptable connectives. They argue further that classical logic, in particular, classical negation, breaks these constraints, so that classical negation, if a cogent notion at all, has a meaning going beyond what can be exhibited in its inferential use. I argue that Dummett gives a mistaken elaboration (...) of the notion of harmony, an idea stemming from a remark of Gerhard Gentzen's. The introduction-rules are autonomous if they are taken fully to specify the meaning of the logical constants, and the rules are harmonious if the elimination-rule draws its conclusion from just the grounds stated in the introduction-rule. The key to harmony in classical logic then lies in strengthening the theory of the conditional so that the positive logic contains the full classical theory of the conditional. This is achieved by allowing parametric formulae in the natural deduction proofs, a form of multiple-conclusion logic. (shrink)
