Wittgenstein’s Tractatus construes the nature of reasoning in a manner which sharply conflicts with the conventional wisdom that logic is normative, not descriptive of thought. For although we sometimes seem to reason incorrectly, Wittgenstein denies that we can make logical mistakes (5.473). My aim in this paper is to show that the Tractatus provides us with good reasons to rethink some of the central assumptions that are standardly made in thinking about the relation between logic and thought. In particular, the (...) rejection of logical mistakes is to be understood in connection with Wittgenstein’s non-psychological approach to the thinking subject (5.641). On Wittgenstein's view, inference, understanding, and meaning are holistically related; cases of defective reasoning are to be explained in terms of a defective grasp of meaning which manifests in an indeterminate use of signs. Invalid reasoning therefore does not count for Wittgenstein as a species of reasoning, but rather as the mere illusion of reasoning. The rejection of logical mistakes thus gives voice to a radical disjunctivist approach. (shrink)

The notion of the riddle plays a pivotal role in Wittgenstein’s Tractatus . By examining the comparisons he draws between philosophical problems and riddles, this paper offers a reassessment of the aims and methods of the book. Solving an ordinary riddle does not consist in learning a new fact; what it requires is that we transform the way we use words. Similarly, Wittgenstein proposes to transform the way philosophers understand the nature of their problems. But since he holds that these (...) problems are ultimately unsolvable, rather than attempting to solve the riddles of philosophy, he aims to dissolve them. (shrink)

The fundamental error of the metaphysical tradition, according to Heidegger, is the subordination of general ontology to the ontology of a special, exemplary entity (God, the soul, etc.). But Being and Time itself treats one kind of entity as exemplary, namely Dasein. Does this mean that Heidegger fails to free himself from the kind of metaphysics that he sought to criticize? To show how he avoids this charge I propose to examine the parallels between the methodology of Being and Time (...) and the methodology Heidegger ascribes to Aristotle's Metaphysics. Heidegger takes the virtue of Aristotle's inquiry to reside in the way he resists the subordination of general to special ontology: Aristotle was guided by a "double concept" of metaphysics, pursued two irreducibly distinct methods of inquiry, and avoided the temptation to unite them. In proposing to similarly pursue a "double task" in Being and Time Heidegger seeks to apply this insight to his own work. Alongside the task of fundamental ontology, Heidegger spells out the shape of a second task, Destruktion, understood as a historical critique that traces ontological concepts back to their ontic roots. But Destruktion is not a mere addendum to fundamental ontology; the two tasks are meant to counterbalance one another and thereby prevent the collapse of the ontological difference between being and beings. Indeed, Heidegger proposes to apply Destruktion to the results of his own fundamental ontology. He hopes to thereby achieve a transformation of the philosophical attitude which underpins the metaphysical tradition. (shrink)

Both Heidegger and Wittgenstein consider the possibility of a philosophical inquiry of an absolutely universal scope—an inquiry into the being of all beings, in Heidegger’s case, and into the logical form of everything that can be meaningfully said, in Wittgenstein’s. Moreover, they both raise the worry that the theoretical language by means of which we speak of particular beings and assert particular facts is not suited to this task. And yet their own philosophical work seems to include many assertions of (...) ordinary, theoretical language. Are they being inconsistent? Or are they hoping to use theoretical language in a way that conveys what cannot be said in that language? Much of the scholarship on each of these thinkers takes the form of one of the two horns of this dilemma. In the context of Wittgenstein scholarship, however, a third alternative has been proposed: the Resolute Reading of the Tractatus. My aim is to establish the availability of a similar solution to Heidegger’s predicament. It will emerge that Heidegger rejects the possibility of a theoretical account of being and pursues a project of a radically different sort, whose goal is to bring about a transformation of our fundamental relation to being.

This chapter investigates how a reading of Wittgenstein along the lines laid out by Cora Diamond makes room for a novel approach to ethical truth. Following Diamond, I develop the connection between the kinds of elucidatory propositions by means of which we spell out and maintain the shape of our theoretical thinking, such as “‘someone’ is not the name of someone” and “five plus seven equals twelve,” and the kind of propositions by means of which we spell out and maintain (...) the shape of ethical thinking, such as “slavery is unjust.” As Diamond points out in connection with the last example, this is a proposition that we take to be an undeniable truth; for anyone who would attempt to negate it would become unintelligible to us. In this sense this ethical truth spells out the limits of ethical thinking. And yet what counts as coherent thought about such matters tends to shift over time. Indeed the great difficulty of overcoming ethical disagreements has to do with the fact that what is at stake in them is not just the content, but the form and limits of thought. Nonetheless, Diamond proposes that ethical propositions may count as genuine truths. For this to make sense, a middle path between realism and relativism must be found. In order to show how this is possible, and in order to defend Diamond’s view, I propose to approach ethical truth by means of a disjunctivist strategy. On this approach, while we, just as much as our interlocutor, may at times be misled in our ethical thinking, and while we may at times fail to shape our ethical thought in ways that prevent us from gaining clarity on ethical matters, this does not detract from the fact that we may at times be right, and that we may then genuinely possess ethical truth.

This paper concerns Wittgenstein’s conception of philosophical and mathematical problems. Both in his earlier and in his later writings Wittgenstein grapples with the tendency of philosophers to misconstrue the nature of the difficulties that they are facing. Whereas philosophers tend to assume that their problems are comparable to those that come up in the sciences, and take these problems to consist in questions the answers to which will provide them with substantive knowledge, Wittgenstein compares philosophical problems with riddles. What is (...) characteristic of riddles is that solving them involves an alteration of the use of language, but it does not tend to involve the acquisition of new knowledge. In his middle and later period, the comparison with riddles serves to highlight and resolve a related confusion in the way philosophers of mathematics understand the nature of mathematical problems. Wittgenstein rejects the realist approach according to which every mathematical theorem, whether proven or not, meaningfully specifies a possible fact which would make it true or false. By contrast, Wittgenstein construes unproven conjectures on the model of riddle phrases, whose meaning, prior to our finding the solution to them, has not been determined. Moreover, Wittgenstein draws our attention to the fact that we can be caught up in an attempt to solve a riddle even if the riddle does not have a solution; the same applies, in his mind, to our engagement with philosophical and mathematical problems. When it comes to philosophical riddles, Wittgenstein is convinced that they do not have a solution at all. The specific difficulty presented by unproven mathematical conjectures is different; in this case, we cannot tell in advance whether or not they present us with a solvable riddle. The paper situates these issues in the context of ongoing debates in the scholarship concerning Wittgenstein’s conception of nonsense, his methodology, his engagement with mathematical realism and verificationism, and his response to skepticism.

In Tractatus 5.132 Wittgenstein argues that inferential justification depends solely on the understanding of the premises and conclusion, and is not mediated by any further act. On this basis he argues that Frege’s and Russell’s rules of inference are “senseless” and “superfluous”. This line of argument is puzzling, since it is unclear that there could be any viable account of inference according to which no such mediation takes place. I show that Wittgenstein’s rejection of rules of inference can be motivated (...) by taking account of his holistic construal of the relation between inference and understanding. (shrink)

Wittgenstein seeks to throw light on our concept of understanding by looking at how misunderstandings arise and what kinds of failure they involve. He discerns a peculiar sort of misunderstanding in the writings of the social anthropologist James Frazer. In Frazer’s hands, the anthropological project of enabling us to understand human behavior seems to yield the result that there are certain forms of human behavior that simply cannot be understood. The source of Frazer’s misunderstanding, according to Wittgenstein, is that he (...) places narrow requirements on what could count as meaningful, prior to and independently of his encounter with the subjects of his interpretation. Frazer, like some of the philosophers Wittgenstein addresses in his other works, succumbs to nonsense in his very attempt to draw the limits of sense. My aim in this chapter is to clarify the connections between Wittgenstein’s criticism of Frazer and his criticism of his fellow philosophers, in particular of Frege. The materials I draw on stem from various periods in Wittgenstein’s career, and they reveal, in my mind, an important continuity in Wittgenstein’s thought: addressing misunderstanding, in Wittgenstein’s view, is fundamentally an ethical problem, not a theoretical one.

By means of a reductio argument, Wittgenstein’s Tractatus calls into question the very idea that we can represent logical form. My paper addresses three interrelated questions: first, what conception of logical form is at issue in this argument? Second, whose conception of logic is this argument intended to undermine? And third, what could count as an adequate response to it? I show that the argument construes logical form as the universal, underlying correlation of any representation and the reality it represents. (...) I further show that the argument seeks to undermine core commitments of Frege’s and Russell’s. But the reductio, as I read it, is not intended to establish the falsity of any of their specific assumptions. Rather, its aim is to make manifest the indeterminacies that underlie the language in which these assumptions are framed, and establish the need for a transformation of that language. So understood, Wittgenstein’s argument exemplifies his idea that philosophy is not a theory, but an activity of elucidation. The interpretation I propose bears on one of the central debates in the literature, namely how we should understand Wittgenstein’s contention that his elucidations succeed despite being nonsensical.

In recent decades, the scientific study of consciousness has significantly increased our understanding of this elusive phenomenon. Yet, despite critical development in our understanding of the functional side of consciousness, we still lack a fundamental theory regarding its phenomenal aspect. There is an “explanatory gap” between our scientific knowledge of functional consciousness and its “subjective,” phenomenal aspects, referred to as the “hard problem” of consciousness. The phenomenal aspect of consciousness is the first-person answer to “what it’s like” question, and it (...) has thus far proved recalcitrant to direct scientific investigation. Naturalistic dualists argue that it is composed of a primitive, private, non-reductive element of reality that is independent from the functional and physical aspects of consciousness. Illusionists, on the other hand, argue that it is merely a cognitive illusion, and that all that exists are ultimately physical, non-phenomenal properties. We contend that both the dualist and illusionist positions are flawed because they tacitly assume consciousness to be an absolute property that doesn’t depend on the observer. We develop a conceptual and a mathematical argument for a relativistic theory of consciousness in which a system either has or doesn’t have phenomenal consciousness with respect to some observer. Phenomenal consciousness is neither private nor delusional, just relativistic. In the frame of reference of the cognitive system, it will be observable and in other frame of reference it will not. These two cognitive frames of reference are both correct, just as in the case of an observer that claims to be at rest while another will claim that the observer has constant velocity. Given that consciousness is a relativistic phenomenon, neither observer position can be privileged, as they both describe the same underlying reality. Based on relativistic phenomena in physics we developed a mathematical formalization for consciousness which bridges the explanatory gap and dissolves the hard problem. Given that the first-person cognitive frame of reference also offers legitimate observations on consciousness, we conclude by arguing that philosophers can usefully contribute to the science of consciousness by collaborating with neuroscientists to explore the neural basis of phenomenal structures.

Despite their clearly demonstrated safety and effectiveness, approved vaccines against COVID-19 are commonly mistrusted. Nations should find and implement effective ways to boost vaccine confidence. But the implications for ethical vaccine development are less straightforward than some have assumed. Opponents of COVID-19 vaccine challenge trials, in particular, made speculative or empirically implausible warnings on this matter, some of which, if applied consistently, would have ruled out most COVID-19 vaccine trials and many non-pharmaceutical responses.

Dynamic Repetition proposes a new understanding of modern Jewish theories of messianism across the disciplines of history, theology, and philosophy. This book explores how ideals of repetition, return, and the cyclical occasioned a new messianic impulse across an important swath of late nineteenth and early twentieth century German Jewish thought.

This paper discusses Hannah Arendt’s model of the Jewish pariah, developed in her study of Jewish assimilation. The argument is that Arendt’s model represents her early efforts to move beyond Martin Heidegger’s philosophy. The paper focuses on Arendt’s concept of a conscious pariah as a model for political resistance, independence, and agency. It shows how Arendt infused elements of Heidegger’s philosophy into her early vision of Jewish politics, while also transcending the limits of Heidegger’s ontological project with her political vision. (...) The paper suggests that Arendt’s book on Rahel Varnhagen shares similarities with Heidegger’s work on Mitsein in Being and Time, while her 1944 model of the conscious pariah, especially the focus on the pariah as a rebel, illustrates her concerns with Heidegger’s work on the Volk.

Artefacts do not always do what they are supposed to, due to a variety of reasons, including manufacturing problems, poor maintenance, and normal wear-and-tear. Since software is an artefact, it should be subject to malfunctioning in the same sense in which other artefacts can malfunction. Yet, whether software is on a par with other artefacts when it comes to malfunctioning crucially depends on the abstraction used in the analysis. We distinguish between “negative” and “positive” notions of malfunction. A negative malfunction, (...) or dysfunction, occurs when an artefact token either does not or cannot do what it is supposed to. A positive malfunction, or misfunction, occurs when an artefact token may do what is supposed to but, at least occasionally, it also yields some unintended and undesirable effects. We argue that software, understood as type, may misfunction in some limited sense, but cannot dysfunction. Accordingly, one should distinguish software from other technical artefacts, in view of their design that makes dysfunction impossible for the former, while possible for the latter. (shrink)

Brain implants, such as Deep Brain Stimulation (DBS), which are designed to improve motor, mood and behavioural pathology, present unique challenges to our understanding of identity, agency and free will. This is because these devices can have visible effects on persons' physical and psychological properties yet are essentially undetectable when operating correctly. They can supplement and compensate for one's inherent abilities and faculties when they are compromised by neuropsychiatric disorders. Further, unlike talk therapy or pharmacological treatments, patients need not ‘do’ (...) anything for the treatment to take effect. If one accepts, as we argue here, that brain implants are unique among implantable types of devices, then this can have significant implications for what it means to persist as the same person and be the source of one's thoughts and actions. By examining two of the most common indications for DBS in current use, namely in the motor (Parkinson's Disease) and psychiatric (Major Depression) domains, we further argue that although DBS, as it is currently applied, does not necessarily represent a unique threat to personal identity and agency per se, it introduces an unprecedented ‘third party’ into the debate on these concepts. In this way, DBS can be used as a tool to begin probing, both conceptually and empirically, some of philosophy's most perennial metaphysical questions. (shrink)

Expert opinions have yielded a wide and controversial assortment of conceptions of free will, but laypersons seem to associate free will more simply with making choices. We found that the more strongly people believed in free will, the more they liked making choices, the higher they rated their ability to make decisions (Study 1), the less difficult they perceived making decisions, and the more satisfied they were with their decisions (Study 2). High free will belief was also associated with more (...) spontaneous associating of choice with freedom, and with the perception of actions as choices. Recalling choices (Study 3) and making choices (Study 4) led to a stronger endorsement of the belief in free will, with an additional effect for the level of choice involved. These findings suggest that the everyday social reality of beliefs about free will is a matter of how people think and feel about choice. (shrink)

Recent findings support the idea that the belief in free will serves as the basis for moral responsibility, thus promoting the punishment of immoral agents. We theorized that free will extends beyond morality to serve as the basis for accountability and the capacity for change more broadly, not only for others but also for the self. Five experiments showed that people attributed higher freedom of will to negative than to positive valence, regardless of morality or intent, for both self and (...) others. In recalling everyday life situations and in classical decision making paradigms, negative actions, negatives outcomes, and negative framing were attributed higher free will than positive ones. Free will attributions were mainly driven by action or outcome valence, but not intent. These findings show consistent support for the idea that free will underlies laypersons’ sense-making for accountability and change under negative circumstances. (shrink)

Dreams are a remarkable experiment in psychology and neuroscience, conducted every night in every sleeping person. They show that the human brain, disconnected from the environment, can generate an entire world of conscious experiences by itself.

In parallel, brain lesion studies, functional imaging and neurophysiology have advanced current knowledge of the neural basis of dreaming. It is now possible to start integrating these two strands of research to address fundamental (...) questions that dreams pose for cognitive neuroscience: how conscious experiences in sleep relate to underlying brain activity; why the dreamer is largely disconnected from the environment; and whether dreaming is more closely related to mental imagery or to perception.

Advances in neuromodulation and an improved understanding of the anatomy and circuitry of psychopathology have led to a resurgence of interest in surgery for psychiatric disease. Clinical trials exploring deep brain stimulation (DBS), a focally targeted, adjustable and reversible form of neurosurgery, are being developed to address the use of this technology in highly selected patient populations. Psychiatric patients deemed eligible for surgical intervention, such as DBS, typically meet stringent inclusion criteria, including demonstrated severity, chronicity and a failure of conventional (...) therapy. Although a humanitarian device exemption by the US Food and Drug Administration exists for its use in obsessive-compulsive disorder, DBS remains a largely experimental treatment in the psychiatric context, with its use currently limited to clinical trials and investigative studies. The combination of a patient population at the limits of conventional therapy and a novel technology in a new indication poses interesting challenges to the informed consent process as it relates to clinical trial enrollment. These challenges can be divided into those that relate to the patient, their disease and the technology, with each illustrating how traditional conceptualisations of research consent may be inadequate in the surgical psychiatry context. With specific reference to risk analysis, patient autonomy, voluntariness and the duty of the clinician-researcher, this paper will discuss the unique challenges that clinical trials of surgery for refractory psychiatric disease present to the consent process. Recommendations are also made for an ethical approach to clinical trial consent acquisition in this unique patient population. (shrink)

Fear can undermine cooperation. It may discourage individuals from collaborating with others because of concerns about potential exploitation; prompt them to engage in defensive aggression by launching a preemptive strike; and propel power-seeking individuals to act dominantly rather than compassionately. Therefore, accumulated evidence requires a more contextualized consideration of the link between fear and cooperation in adults.

Existential threat lies at the heart of intergroup conflict, but the literature on existential concerns lacks clear conceptualization and integration. To address this problem, we offer a new conceptualization and measurement of existential threat. We establish the reliability and validity of our measure, and to illustrate its utility, we examine whether different existential threats underlie the association between political ideology and support for specific political policies. Study 1 (N = 798) established the construct validity of the scale, and revealed four (...) distinct existential threats: personal death, physical collective annihilation, symbolic collective annihilation, and past victimization. Study 2 (N = 424) confirmed the 4-factor structure, and the convergent and discriminant validity of the scale. Study 3 (N = 170) revealed that the association between a hawkish political ideology and support for hardline policies was mediated by past victimization, whereas the association between a dovish political ideology and conciliatory policies was mediated by concerns over collective symbolic annihilation. Study 4 (N = 503) conceptually replicated the pattern of findings found in Study 3, and showed that at times of conflict, physical collective annihilation concerns also mediate the relationship between hawkish ideologies and support for hardline policies. In both Studies 3 and 4, when controlling for other threats, personal death did not play a significant role. These results underscore the need to consider the multidimensional nature of existential threat, especially in the context of political conflict. (shrink)

Moses and Monotheism brings together fundamental new contributions to discourses on Freud and Moses, as well as new research on the intersections of theology, political theory, and history in Freud's psychoanalytic work.

This article suggests a rereading of Schelling’s theory of freedom in the through Freud’s psychoanalytic theory. Schelling’s philosophy of freedom manifested a latent essentialism of the idealistic formulation of human freedom. In Schelling’s scheme, free was “what acts only in accord with the laws of its own being.” In practice, Schelling theory of freedom was based on an intelligible act in the “beginning of creation” which set an eternal unreachable essence to the subject. I propose to read “Schelling through Freud” (...) as a way to revisit this theoretical structure. I argue that Freud’s theory of early libido formation should be recognized as a naturalistic formulation of the intelligible unconscious act. This allows Freud to restructure Schelling’s unconscious eternal essence. Freud’s shift from the metaphysical to the metapsychological drama suggests a human intervention in place of divine redemption, and, thus transpires as a modern articulation of German Idealism.

Is the mathematical function being computed by a given physical system determined by the system’s dynamics? This question is at the heart of the indeterminacy of computation phenomenon (Fresco et al. [unpublished]). A paradigmatic example is a conventional electrical AND-gate that is often said to compute conjunction, but it can just as well be used to compute disjunction. Despite the pervasiveness of this phenomenon in physical computational systems, it has been discussed in the philosophical literature only indirectly, mostly with reference (...) to the debate over realism about physical computation and computationalism. A welcome exception is Dewhurst’s ([2018]) recent analysis of computational individuation under the mechanistic framework. He rejects the idea of appealing to semantic properties for determining the computational identity of a physical system. But Dewhurst seems to be too quick to pay the price of giving up the notion of computational equivalence. We aim to show that the mechanist need not pay this price. The mechanistic framework can, in principle, preserve the idea of computational equivalence even between two different enough kinds of physical systems, say, electrical and hydraulic ones. (shrink)

Norm theory (Kahneman & Miller, 1986) described a tendency for people to associate stronger regret with a negative outcome when it is a result of an exception (abnormal behavior) compared to when it is a result of routine (normal behavior). In two pre-registered studies, we conducted a replication and extension of three classic experiments on past behavior exception/routine contrasts (N = 684). We successfully replicated Kahneman and Miller’s (1986) experiments with the classic hitchhiker-scenario (Part 1) and car accident-scenario (Part 2). (...) In both cases, participants examined negative outcomes and tended to indicate a protagonist who deviated from own past behavior as more regretful than another who followed routine. Pre-registered extensions also showed effects for ratings of social norms, negative affect, and perceived luck. We did not find support for the Miller and McFarland (1986) experiment robbery scenario (Part 3) using a compensation measure, in that compensation to a victim of a robbery was not significantly different comparing exceptional and routine circumstances. However, a pre-registered extension showed that robbery under exceptional circumstances was regretted more than robbery under routine circumstances. We discuss implications for current and future research. (shrink)

Recent developments in the field of neurosurgery, specifically those dealing with the modification of mood and affect as part of psychiatric disease, have led some researchers to discuss the ethical implications of surgery to alter personality and personal identity. As knowledge and technology advance, discussions of surgery to alter undesirable traits, or possibly the enhancement of normal traits, will play an increasingly larger role in the ethical literature. So far, identity and enhancement have yet to be explored in a neurosurgical (...) context, despite the fact that 1) neurological disease and treatment both potentially alter identity, and 2) that neurosurgeons will likely be the purveyors of future enhancement implantable technology. Here, we use interviews with neurosurgical patients to shed light on the ethical issues and challenges that surround identity and enhancement in neurosurgery. The results provide insight into how patients approach their identity prior to potentially identity-altering procedures and what future ethical challenges lay ahead for clinicians and researchers in the field of neurotherapeutics.

Do the dynamics of a physical system determine what function the system computes? Except in special cases, the answer is no: it is often indeterminate what function a given physical system computes. Accordingly, care should be taken when the question ‘What does a particular neuronal system do?’ is answered by hypothesising that the system computes a particular function. The phenomenon of the indeterminacy of computation has important implications for the development of computational explanations of biological systems. Additionally, the phenomenon lends (...) some support to the idea that a single neuronal structure may perform multiple cognitive functions, each subserved by a different computation. We provide an overarching conceptual framework in order to further the philosophical debate on the nature of computational indeterminacy and computational explanation. (shrink)
