Part I presents a model of interactive computation and a metric for expressiveness, Part II relates interactive models of computation to physics, and Part III considers empirical models from a philosophical perspective. Interaction machines, which extend Turing Machines to interaction, are shown in Part I to be more expressive than Turing Machines by a direct proof, by adapting Gödel's incompleteness result, and by observability metrics. Observation equivalence provides a tool for measuring expressiveness according to which interactive systems are more expressive (...) than algorithms. Refinement of function equivalence by observation of outer interactive behavior and inner computation steps is examined. The change of focus from algorithms specified by computable functions to interaction specified by observation equivalence captures the essence of empirical computer science. Part II relates interaction in models of computation to observation in the natural sciences. Explanatory power in physics is specified by the same observability metric as expressiveness in interactive systems. Realist models of inner structure are characterized by induction, abduction, and Occam's Razor. Interactive realism extends the hidden-variable model of Einstein to hidden interfaces that provide extra degrees of freedom to formulate hypotheses with testable predictions conforming with quantum theory. Greater expressiveness of collaborative computational observers (writers) than single observers implies that hidden-interface models are more expressive than hidden-variable models. By providing a common foundation for empirical computational and physical models we can use precise results about computational models to establish properties of physical models. Part III shows that the evolution in computing from algorithms to interaction parallels that in physics from rationalism to empiricism. Plato's cave metaphor is interactively extended from Platonic rationalism to empiricism. The Turing test is extended to TMs with hidden interfaces that express interactive thinking richer than the traditional Turing test. Interactive (nonmonotonic) extensions of logic such as the closed-world assumption suggest that interactiveness is incompatible with monotonic logical inference. Procedure call, atomicity of transactions, and taking a fixed point are techniques for closing open systems similar to "preparation" followed by "observation" of a physical system. Pragmatics is introduced as a framework for extending logical models with a fixed syntax and semantics to multiple-interface models that support collaboration among clients sharing common resources.

The classical view of computing positions computation as a closed-box transformation of inputs (rational numbers or finite strings) to outputs. According to the interactive view of computing, computation is an ongoing interactive process rather than a function-based transformation of an input to an output. Specifically, communication with the outside world happens during the computation, not before or after it. This approach radically changes our understanding of what is computation and how it is modeled. The acceptance of interaction as a new (...) paradigm is hindered by the Strong Church–Turing Thesis (SCT), the widespread belief that Turing Machines (TMs) capture all computation, so models of computation more expressive than TMs are impossible. In this paper, we show that SCT reinterprets the original Church–Turing Thesis (CTT) in a way that Turing never intended; its commonly assumed equivalence to the original is a myth. We identify and analyze the historical reasons for the widespread belief in SCT. Only by accepting that it is false can we begin to adopt interaction as an alternative paradigm of computation. We present Persistent Turing Machines (PTMs), that extend TMs to capture sequential interaction. PTMs allow us to formulate the Sequential Interaction Thesis, going beyond the expressiveness of TMs and of the CTT. The paradigm shift to interaction provides an alternative understanding of the nature of computing that better reflects the services provided by today’s computing technology. (shrink)

Wegner (Wegner, D. (2002). The illusion of conscious will. MIT Press) argues that conscious will is an illusion, citing a wide range of empirical evidence. I shall begin by surveying some of his arguments. Many are unsuccessful. But one—an argument from the ubiquity of self-interpretation—is more promising. Yet is suffers from an obvious lacuna, offered by so-called ‘dual process’ theories of reasoning and decision making (Evans, J., & Over, D. (1996). Rationality and reasoning. Psychology Press; Stanovich, K. (1999). (...) Who is rational? Studies of individual differences in reasoning. Lawrence Erlbaum; Frankish, K. (2004). Mind and supermind. Cambridge University Press). I shall argue that this lacuna can be filled by a plausible a priori claim about the causal role of anything deserving to be called ‘a will.’ The result is that there is no such thing as conscious willing: conscious will is, indeed, an illusion.

With the success of cognitive science's interdisciplinary approach to studying the mind, many theorists have taken up the strategy of appealing to science to address long standing disputes about metaphysics and the mind. In a recent case in point, philosophers and psychologists, including Robert Kane, Daniel C. Dennett, and Daniel M. Wegner, are exploring how science can be brought to bear on the debate about the problem of free will. I attempt to clarify the current debate by considering how (...) empirical research can be useful. I argue that empirical findings don't apply to one basic dimension of the problem, namely the dispute between compatibilism and incompatibilism. However, I show that empirical research can provide constraints in connection with another fundamental dimension, namely the dispute between libertarianism, which claims that indeterminacy is, in certain contexts, sufficient for freedom, and hard determinism and compatibilism, which deny this. I argue that the source of the most powerful constraint is psychological research into the accuracy of introspection. (shrink)

‘Smart’ devices are becoming increasingly ubiquitous. While these sophisticated machines are useful for various purposes, they sometimes evoke feelings of eeriness or discomfort that constitute uncanniness, a much-discussed phenomenon in robotics research. Adult participants (N = 115) rated the uncanniness of a hypothetical future smart speaker that was described as possessing the mental capacities for experience, agency, neither, or both. The novel condition prompting participants to attribute both agency and experience to the speaker filled an important theoretical gap in the (...) literature. Consistent with the mind perception hypothesis of uncanniness (MPH; Gray & Wegner, 2012), participants in the with-experience condition rated the device significantly higher in uncanniness than those in the control condition and the with-agency condition. Participants in the with-both (experience and agency) condition also rated the device higher in uncanniness than those in the control condition and the with-agency condition, although this latter difference only approached statistical significance.

The notion of interaction and interaction machines, developed by Peter Wegner, includes the comparison between incompleteness of interaction machines and Gödel incompleteness. However, this comparison is not adequate, because it combines different notions and different sources of incompleteness. In particular, it merges syntactic with two senses of semantic completeness, and results about truth with results about provability and their consequences . The comparison also overlooks structural differences in the way diagonalization produces incompleteness. More generally, the comparison is unlikely (...) because interaction incompleteness is supposed to come from a system's involvement with its environment, whereas Gödel incompleteness comes from a system's involvement with itself.

In 1936, G. Birkhoff and J. v. Neumann published an article with the title The logic of quantum mechanics'. In this paper, the authors demonstrated that in quantum mechanics the most simple observables which correspond to yes-no propositions about a quantum physical system constitute an algebraic structure, the most important proper ties of which are given by an orthocomplemented and quasimodular lattice Lq. Furthermore, this lattice of quantum mechanical proposi tions has, from a formal point of view, many similarities with (...) a Boolean lattice L8 which is known to be the lattice of classical propositional logic. Therefore, one could conjecture that due to the algebraic structure of quantum mechanical observables a logical calculus Q of quantum mechanical propositions is established, which is slightly different from the calculus L of classical propositional logic but which is applicable to all quantum mechanical propositions. This calculus has sometimes been called 'quan tum logic'. However, the statement that propositions about quantum physical systems are governed by the laws of quantum logic, which differ from ordinary classical logic and which are based on the empirically well-established quantum theory, is exposed to two serious objec tions: Logic is a theory which deals with those relationships between various propositions that are valid independent of the content of the respective propositions. Thus, the validity of logical relationships is not restricted to a special type of proposition, e. g. to propositions about classical physical systems. (shrink)

On being told that "translation is an impossible thing," Anatole France replied: "precisely, my friend; the recognition of that truth is a necessary preliminary to success in art." The task of Transplantings is to add flesh and bones to that familiar quip. Indeed, Daniel Weissbort notes that Viereck's study represented a sixty-five year long project. Now, it is finally being brought to print in its full form, with the completion of the final manuscript shortly before Viereck's death. If translation is (...) a special genre in its own right, the translation of poetry, especially from major foreign languages, is a special subset of that genre. What emerges in the imperfect act of translation is an aesthetic dimension that Viereck considers unique in its own right. Transplantings provides new insight into Viereck as a poet of substance, but more than that as a public intellectual. He is critical in probing the work of the major figures such as Stefan George and Georg Heym. To round out this monumental new look at German poetical history, Viereck reviews Goethe, Novalis, and Rilke among others. For Viereck, the difference between the poetical and the political is critical. The quality of poetry is not measured by politics, nor can the worth of political action be defined by commitment to the poetical. The experience of German thought, as well as French and Italian efforts, reveals a divide that can be narrowed but hardly bridged by rhetoric. Transplantings does not simplify the task of the reader. Rather it shows without doubt that the passion of great poetry is part of a national tradition. Efforts at translation indicate how such poetry becomes part of an international culture. This is a major work by one of the great thinkers of the twentieth century. It merits reading, and then, re-reading. "Peter Viereck was that rare scholar who captured the European experience with America, while fully realizing the American encounter with Europe. He did so with consciousness of and compassion for both sectors of Western Civilization" --Irving Louis Horowitz, Society Peter Viereck was a Pulitzer Prize-winning poet, critic, and historian. He held the Kenan Chair in History at Mount Holyoke College. He was known as one of America's conservatism's early leaders and was the recipient of Guggenheim Fellowships both in history and poetry.

Fabienne Peter on whether difficult political decisions should be made by experts.

Early modern experimental philosophers were opposed to speculation, and yet many endorsed speculative theories. This chapter gives a partial explanation of why this is so, using Robert Boyle’s acceptance and promotion of the corpuscular philosophy as a case study. It argues that, in addition to furnishing experimental evidence for the corpuscular hypothesis in his Forms and Qualities, Boyle attempted to establish its epistemic superiority over other speculative theories on the grounds that it is founded upon superior principles. In his ‘Excellency (...) and Grounds of the Mechanical Hypothesis’, Boyle claims that the principles of the corpuscular philosophy are more intelligible, more parsimonious, ontologically primary, simpler and more comprehensive than those of its rivals. On grounds of comparative plausibility then, according to Boyle, the corpuscular philosophy is eminently preferable to its rivals. The final section of the chapter traces the legacy of Boyle’s appraisal of the epistemic status of the corpuscular philosophy in the writings of many of his compatriots from the mid-1660s to the Cyclopedia of Ephraim Chambers of 1728.

_ Source: _Volume 94, Issue 3, pp 381 - 390 Reference can fail in a way that intentionality cannot. Though the stream of phenomenal experience typically does not fail to target objects outside, it may do. How does the mind go about targeting objects beyond itself? The speculative conjecture of this paper is that it does so by a type of process which can be called _pointing_, and that the acts or act-aspects of pointing can be called _pointers_. The notion (...) of a pointer has several suggestive roots. One is the familiar physical gesture of pointing. Another is the existence of directional signs such as on roads. The third is the software data types making direct reference to memory locations in computers, also called ‘pointers’. A final source is demonstrative pronouns and other deictic expressions in language, of which Peter Geach wrote, “a demonstrative pronoun … works like a pointer, not like a label”. I suggest that there is in the mental cognitive repertoire a structurally and semantically analogous type of act which pierces the passivity of perception, directs us outside the machine, and prepares the way for drawing others’ minds to the same thing.

At the heart of Peter Singer’s utilitarianism is the impartial weighing of the interests of those affected by our actions. Singer calls this the Principle of Equal Consideration of Interests. This paper argues that Singer’s Principle does not accord with our moral intuitions and the logic of our moral thinking. It discusses the Principle in the context of the parable of the Prodigal Son and his Brother – a parable that raises the issue of impartiality in a particularly challenging (...) way. What the parable shows is, first, that our moral thinking often turns on judgements of fairness that are prior to any impartial weighing of interests; and, second, that impartial fairness itself is sometimes transcended by compassionate love. Both of these points have important implications for bioethics. (shrink)

Tragedy plays a central role in Hegel's early writings on theology and politics. Hegel’s overarching aim in these texts is to determine the kind of mythology that would best complement religious and political freedom in modernity. Peter Wake claims that, for Hegel at this early stage, ancient Greek tragedy provided the model for such a mythology and suggested a way to oppose the rigid hierarchies and authoritarianism that characterized Europe of his day. Wake follows Hegel as he develops his (...) idea of the essence of Christianity and its relation to the distinctly tragic expression of beauty found in Greek mythology. (shrink)

Peter Stone’s review of my The ABC of Armageddon: Bertrand Russell on Science, Religion and the Next War, – is so irretrievably muddled that when he concludes “a thoroughly confused book ends on a thoroughly confused note”, this state of confusion most accurately represents the condition of the reviewer. The problem here is not an author and his book “adrift at Armageddon”, as the title of Stone’s review maintains, but a reviewer rowing furiously with one oar. Whatever inadequacies there are in The ABC of Armageddon, they are not those Stone so enthusiastically catalogues in his series of speculations as to what I might have done, but didn’t. In awaiting this review in Russell, I worried about how my various suggestions about Russell’s writing in the interwar period—even my definition of what the interwar period was—would be received. To list a few: the idea that the Great War constituted a dividing line in his work, and why; that his work in the interwar period should be judged as a whole; that his work in the interwar period was worth evaluating, not simply being dismissed as evidence of early philosophical dotage; the way Russell’s published ideas were entwined with those of his Anglo-American contemporaries; the theme of the “old savage in the new civilization” in Russell’s work, and in that of his contemporaries; the dimension of “rhetorical performance” and Russell’s deliberate stance as a  Russell, n.s.  (): – (at ). russell: the Journal of Bertrand Russell Studies n.s.  (summer ): – The Bertrand Russell Research Centre, McMaster U.  -  Discussion preacher; the differences between The Prospects of Industrial Civilization and The Scientific Outlook, on the one hand, and Religion and Science and Power: a New Social Analysis, on the other; the possible influence of Albert Schweitzer on the value of “an operational metaphysic” that allowed an older Russell to act as though ideas like “reverence for life” were true, even if they could not be proven. The list could continue. Stone overlooks all of these ideas, preferring instead to demonstrate my inability to hit targets at which he feels I should have aimed, characterizing my approach and my intentions in some unhelpful ways that are well wide of the mark. I was astounded to learn, for example, that I “assume the role of a political theorist towards Russell’s work”, and thus I “attempt to lay out an argument by Russell and critique it, so as to leave behind a stronger argument in its wake” (p. ). Because I am a political theorist, Stone concludes, “this book is simply a failure as a work of history” (p. ). Instead, being an historian he says, would have involved “situating Russell’s views in the personal and social context in which they emerged.” Writing as a “political theorist” himself (out of the Political Science department at Rochester University, where he is adjunct faculty), Stone’s defence of the historical approach is no doubt well intentioned. Had he followed his own prescription, however, he would have found this book to be substantially the same text as my dissertation (“The Old Savage and the Scientific Outlook: Science, Religion and Social Ethics in the Writings of Bertrand Russell, – ” [McMaster, ]). In the prefatory material appropriate to dissertations in Religious Studies (but not to books intended to sell) Stone would have found some of the acknowledgements and explanations whose absence he found the most irksome. Having dubbed me a political theorist, he excoriates me for an inadequate understanding of utilitarianism, instrumentalism, pragmatism and so on, utterly  In an editorial note discouraged by my editors at  Press but still permitted here, I cannot resist responding to Stone’s editorial notes disparaging the “highly inadequate” citations of Russell studies literature.

_A renowned scholar’s reflections on the romantic period, its disparate participants, and our unacknowledged debt to them_ With his usual wit and élan, esteemed historian Peter Gay enters the contentious, long-standing debates over the romantic period. Here, in this concise and inviting volume, he reformulates the definition of romanticism and provides a fresh account of the immense achievements of romantic writers and artists in all media. Gay’s scope is wide, his insights sharp. He takes on the recurring questions about (...) how to interpret romantic figures and their works. Who qualifies to be a romantic? What ties together romantic figures who practice in different countries, employ different media, even live in different centuries? How is modernism indebted to romanticism, if at all? Guiding readers through the history of the romantic movement across Britain, France, Germany, and Switzerland, Gay argues that the best way to conceptualize romanticism is to accept its complicated nature and acknowledge that there is no “single basket” to contain it. Gay conceives of romantics in “families,” whose individual members share fundamental values but retain unique qualities. He concludes by demonstrating that romanticism extends well into the twentieth century, where its deep and lasting impact may be measured in the work of writers such as T. S. Eliot and Virginia Woolf. (shrink)

A major problem with the Christian doctrine of the Incarnation is that Jesus is meant to be both God and man. Richard Swinburne attempts to overcome the problem by having it that in him there are two consciousnesses – the consciousness of being God, and the consciousness of being a man. This position is rejected, on the Aristotelian ground that one consciousness is enough to explain with dignity the mind of Christ.

In this chapter, Amato explores the concept of “vernacular rationality” introduced by Emmanuel Chukwude Eze in his On Reason: Rationality in a World of Cultural Conflict and Racism. Amato interrogates the different ways this idea can be unfolded, expanded, and developed in the spirit if not the letter of Eze’s employment in relation to Hans-Georg Gadamer’s Philosophical Hermeneutics—in particular, its conception of the role tradition plays in the pursuit of understanding and the idea of hermeneutics as practical philosophy. A more (...) hermeneutical conception of vernacular rationality would have the benefit of embracing the linguisticality of our circumstance, and reorienting our rationality toward one another in conversation and dialogue. From the standpoint of Philosophical Hermeneutics this requires us to engage in a critical-constitutive relation toward our tradition(s), emphasizing the work of listening within and between tradition(s), and broadening the circle of listening so as to strengthen the practical connections that allow conversation and dialogue to overcome the irrational and inhumane.

Scheuerman’s book is one of the handful of significant attempts to rethink Schmitt’s work systematically over the past four decades. In so doing, he raises three key questions for me. First, is Schmitt’s work a sincere contribution to legal and political theory, or an attempt to argue for setting the rule of law aside for authoritarianism, that is, an instrumental critique of indeterminacy? Second, to what extent is Schmitt – critical of the ‘bourgeois’ rule of law, critical of globalization – (...) really a thinker defending capitalism? Can he really be associated with the Ordoliberals (even if they adopted his arguments from 1931 to 1932 in their own writing of the time)? Third, to what extent were Schmitt’s early contributions to National Socialist law aimed at responding to legal indeterminacy, and to what extent did they in fact point towards a radicalism of German law within the Nazi system, especially insofar as they endorsed making decisions based on the principles of justice of the Nazi state – and potentially against the express language of statutes?

As argumentation theory has moved away from classical logic as a standard, sources have played an increasingly important role in the psychology of argumentation. Considering the connections between arguments and their sources is important for both descriptive and normative projects.

We argue for a reconciliation of these different approaches around a probabilistic (...) notion of relevance. (shrink)

Although generally philosophers have put a high valuation on reason, increasingly the role of emotions in motivating action is being recognized.
