Resumo Qual o papel da religião numa sociedade secularizada? Qual o papel da Igreja? O artigo propõe uma reflexão sobre essas questões a partir de um "diálogo virtual" entre o teólogo alemão Dietrich Bonhoeffer (1906-1945) e o filósofo italiano contemporâneo Gianni Vattimo. Esses dois autores, separados pelo tempo e pela geografia, aproximam-se, no entanto, na forma de pensar o fenômeno da secularização - ambos a entendem como algo intrínseco ao Ocidente cristão. A dissolução do sacro e o movimento em direção (...) à autonomia humana foram percebidos por esses dois pensadores não como ameaças à religião cristã, mas como possibilidades de sua plena realização, concretizada por meio do engajamento social. Diante do fim das certezas e das verdades absolutas - quadro pós-moderno que já se delineava na década de 1940 e ganha contornos mais precisos no princípio do século XXI, tanto Bonhoeffer quanto Vattimo pensaram uma teologia capaz de abrir mão dos pressupostos metafísicos. Palavras-chave: Filosofia; Teologia; Pós-modernidade; Secularização; Eclesiologia.What is the role of religion in a secularized society? What is the role of the Church? This article suggests a reflection on these questions based on a "virtual dialogue" between German theologian Dietrich Bonhoeffer (1906-1945) and contemporary Italian philosopher Gianni Vattimo. Though separated by time and geography, those authors are close to each other in the way they view the secularization phenomenon - both understand it as intrinsic to the Christian West. The dissolution of the sacred and the movement towards human autonomy were perceived by the two thinkers not as threats to the Christian religion, but as possibilities of its full accomplishment, made real by social commitment. Facing the end of certainties and absolute truths - a postmodern framework that starts to take shape in the 1940s and acquires more definite contours in the beginning of the 21st century - Bonhoeffer and Vattimo were able to think a theology capable of giving up its metaphysical presuppositions. Key words: Philosophy; Theology; Postmodernity; Secularization; Ecclesiology. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:BOOK REVIEWS 145 Luther on Thomas Aquinas: The Angelic Doctor in the Thought of the Reformer. By DENIS R. JANZ. Veroffentlichungen des Instituts fiir Europiiische Geschichte Mainz, Abt. Religionsgeschichte, Bd. 140. Stuttgart: Franz Steiner Verlag, 1989. Pp. ii + 124. DM 38 {cloth). As Denis Janz, specialist in the late medieval context of Luther's thought (Luther and Late Medieval Thomism, 1983), points out in the "Prospectus," a study of (...) Luther's understanding of Thomas has an inherent appeal, for, " rightly or wrongly, Thomas and Luther are inevitably regarded as the standard-bearers of Roman Catholicism and Protestantism" {p. 1). The recent completion of the necessary critical indices has made the task possible, and the result is a fine and necessary contribution to the work of all scholars interested in the thought of these two pivotal Christian thinkers. The method of Janz is straightforward: assemble the references to Thomas in Luther's works, organize them into appropriate categories, exegete their meanings, and discern important tendencies or perspectives common to these texts. Then "the accuracy of Luther's understanding and the cogency of his critique " can be evaluated from the perspective of twentieth cenrtury historical knowledge {p. 2). Janz recognizes that there are significant hermeneutical difficulties inherent in such a study and that any evaluation " may well imply a notion of history as progress, perhaps even a confidence in the intellectual superiority of modernity over the past " (p. 3). The result bears out the soundness of his approach. Chapter I examines "Luther on the Person of Thomas." Luther, sharing in and contributing to his time's distinctive theological polemic, had no shortage of epithets for Thomas, from " Sophist " to " beggarly paunch " {p. 4). The remarkable thing is the surprising number of complimentary things he has to say. At different times of his career Luther referred to Thomas as " this holy man " or " a man of ' great genius '... woefully misunderstood " {p. 5). A most interesting example is the different uses he makes of a story of Thomas's struggle with despair when near death, when Thomas faced his Anfechtung by holding the Bible and saying "I believe what is in this book" (p. 8). Sometimes Luther cites it as an example of the weakness of implicit faith; but other times he makes no critical comment on Thomas, and the story implies the victory of faith over despair. These different uses show the ambiguity of Luther's attitude toward Thomas as a person, and what in balance seems to be " grudging respect " for an " example of how great persons can at the same time be seriously mistaken " (p. 10). 146 BOOK REVIEWS Chapter U, which comprises the bulk of the hook, carefully examines the substantive issues on which Luther mentions and responds to Thomas: experience, the use of Aristotle, Scripture, penance and indulgences, the Lord's Supper, monasticism, justification, law, baptism, angels, papal authority, purgatory, and the veneration of images. On some of these issues Janz sees only a minor critique of Thomas by Luther and sometimes little real difference between their positions. Both Luther and Thomas give primacy to the literal sense of Scripture, and "both teach that the Church and theology stand under the authority of Scripture" (p. 30). On this question Luther's critique has more to do with the Thomists than Thomas. In regard to penance and indulgences Luther criticizes Thomas's view, though here again there is distortion of Thomas by the Thomists, which Luther correctly suspects (pp. 44-45). Though Luther disagrees with Thomas's understanding of the Lord's Supper, he feels Thomas was entitled to his opinion; what he cannot bear is how Thomas has been raised " to the level of an infallible teacher," with his opinions transformed "into articles of faith" (p. 48). Justification, the heart of Luther's thought, is "a relatively insignificant issue " in his critique of Thomas, as Luther eventually comes to understand better the key place Thomas gave grace (pp. 60, 61). Luther sees Christ as the " abrogation " of the law and criticizes Thomas for not seeing it this way; however, this is a linguistic misunderstanding of Thomas, probably based on Gabriel Bicl's teaching, so that Thomas and Luther are...

The purpose of this paper is to examine the dialogical and creative character of pedagogic work by analyzing the affinities between Martin Buber's I-Thou relation and Lev Semenovich Vygotsky's Zone of Proximal Development. Backed up by empirical studies on the teacher-student relation, we understand that education can only result in students' development if meaningful processes are undertaken. The paper asserts that education shall primarily aim at promoting relational possibilities.

The tuning-fork model of human social cognition, based on the discovery of mirror neurons (MNs) in the ventral premotor cortex of monkeys, involves the four following assumptions: (1) mirroring processes are processes of resonance or simulation. (2) They can be motor or non-motor. (3) Processes of motor mirroring (or action-mirroring), exemplified by the activity of MNs, constitute instances of third-person mindreading, whereby an observer represents the agent's intention. (4) Non-motor mirroring processes enable humans to represent others' emotions. After questioning (...) all four assumptions, I point out that MNs in an observer's brain could not synchronically resonate with MNs in an agent's brain unless they discharged in a single brain in two distinct tasks at different times. Finally, I sketch a conceptualist alternative to the resonance model according to which a brain mechanism active in both the execution and the perception of e.g., the act of grasping is the neural basis of the concept of e.g., grasping.

Abstract: Proponents of the this-universe objection to fine-tuning arguments for a multiverse claim that while the multiverse hypothesis raises the probability that some universe is fine-tuned for life, it fails to raise the probability that this one is. Because that is so, they further argue, those who take the fine-tuning of this universe as evidence for the multiverse hypothesis are guilty of a probabilistic fallacy. I argue that a proper evaluation of the this-universe objection requires the development of (...) a general, formal framework for reasoning probabilistically with evidence statements expressed using indexical terms (such as the statement This universe is fine-tuned). I proceed to develop such a framework and then to apply it to the this-universe objection. While my primary aim is to defend the this-universe objection from recent rebuttals, a secondary aim is to exhibit the utility of the framework itself, which has the potential for wider application.

This chapter considers two types of fine‐tuning, those dealing with the initial conditions of the universe and those based on fixed parameters. Three approaches have been taken to argue that fine‐tuning does not need any special explanation. The first is an appeal to coincidence. The second is that the data are biased by our own observations. The third has to do with the nature of probability itself. The chapter assesses each of these objections in detail. Many naturalistic explanations (...) have been offered for fine‐tuning. The chapter considers the three most important ones. The first is that future discoveries might show that fine‐tuning was not improbable after all. The second is that other life‐permitting ranges for the fine‐tuned constants (FTCs) might exist, allowing for exotic forms of life unlike ours. The third is that we might live in a multiverse of many different universes all with different values of FTCs. (shrink)

Now commonly accepted as the point of reference for musicians in the Western world, A 440 hertz only became the standard pitch during an international conference held in 1939. The adoption of this norm was the result of decades of negotiations between countries involving performers, composers, diplomats, physicists, and sound engineers. Although musicians and musicologists are aware of the variability of musical pitches over time, as attested by the use of lower frequencies to perform early music repertoires, no study has (...) fully explained the invention of our current concert pitch. In this book, Fanny Gribenski draws on a rich variety of previously unexplored archival sources and a unique combination of musicological perspectives, transnational history, and science studies. Tuning the World demonstrates the aesthetic, scientific, industrial, and political contingencies underlying the construction of one of the most "natural" objects of contemporary musical performance, itself the result of a cacophony of competing views and interests.

This paper defends the view that discovering that our universe is fine-tuned should make us more confident that other universes exist. My defense exploits a distinction between ideal and non-ideal evidential support. I use that distinction in concert with a simple model to disarm the most influential objection—the this-universe objection—to the view that fine-tuning supports the existence of other universes. However, the simple model fails to capture some important features of our epistemic situation with respect to fine-tuning. To (...) capture these features, I introduce a more sophisticated model. I then use the more sophisticated model to show that, even once those complicating factors are taken into account, fine-tuning should boost our confidence in the existence of other universes.

Jan Greben criticized fine-tuning by taking seriously the idea that “nature is quantum mechanical”. I argue that this quantum view is limited, and that fine-tuning is real, in the sense that our current physical models require fine-tuning. Second, I examine and clarify many difficult and fundamental issues raised by Rüdiger Vaas’ comments on Cosmological Artificial Selection.

While my primary aim is to defend the this-universe objection from recent rebuttals, a secondary aim is to exhibit the utility of the framework itself, which has the potential for wider application.

The idea that there might be multiple universes with different parameters of nature is often considered an attractive response to the finding that various parameters appear to be delicately fine-tuned for life. The present paper investigates whether the appeal to fine-tuning can legitimately be combined with an appeal to independent empirical evidence for other universes or whether, as suggested by Cory Juhl, combining such appeals inevitably results in illegitimate double counting of the finding that the parameters are right for (...) life. In doing so, the paper takes into account the fact that the parameters' life-friendliness is old evidence for us, which makes Bayesianism's problem of old evidence relevant to Bayesian analysis of its evidential impact. Ultimately, the verdict reached is that the warning of double counting is helpful, but that double counting can in principle be avoided. The paper highlights remaining independent challenges against the fine-tuning argument for the multiverse. (shrink)

Can a set of musical metaphors in a treatise on ethics reveal something about the nature and source of moral autonomy? This article argues that it can. It shows how metaphorical usage of words like tone, pitch, and concord in Adam Smith's Theory of Moral Sentiments can be understood as elements of an analogical model for morality. What this model tells us about morality depends on how we conceptualise music. In contrast to earlier interpretations of Smith's metaphors that have seen (...) music as an aesthetic object, this article sees music as a practice. Understood in this way, the analogy allows us to see morality too as a practice––as moral tuning. This in turn reveals a novel answer to the intractable problem of conventionalism: moral autonomy consists in the freedom inherent in the constant need to interpret and reinterpret the strictly formal ideal of perfect propriety.

Tuning might be the figure best suited to joining this pair of apparently incongruous texts, tuning in the sense defined by David Antin as “a negotiated concord or agreement based on vernacular physical actions with visible outcomes like walking together,” as opposed to understanding, which is predicated, Antin contends, “on a geometrical notion of congruence.”.

Through an enactive perspective, the concept of productive imagination can be rethought as acquired sensorimotor skills. I propose that the genesis and tuning of productive imagination through ….

In “Making Music Together: A Study in Social Relationship,” Alfred Schutz offers a phenomenological description of a structure he contends is at the root not only of shared musical meaning, but of human communication and social relations as such: the “tuning-in relationship.” The aim of what follows is to establish that this same structure is at the root of ethical relationships, which may shed some light on the conditions under which it is possible to respond appropriately to ethically fraught (...) situations. Schutz’ analysis of the play of internal and external time establishes what the tuning-in relationship must be, but not yet how it is possible. His account also points to two important preconditions of tuning in: embodiment as the middle term between internal and external time, and practices as more widely shared meaning contexts which may persist across generations. For several reasons, Schutz does not give embodiment its due in his account, though his earlier work on course-of-action types sheds some light on the nature of practices. In all, though, these amount to promising leads for further investigation. (shrink)

The idea that perceptual and cognitive systems must incorporate knowledge about the structure of the environment has become a central dogma of cognitive theory. In a Bayesian context, this idea is often realized in terms of “tuning the prior”—widely assumed to mean adjusting prior probabilities so that they match the frequencies of events in the world. This kind of “ecological” tuning has often been held up as an ideal of inference, in fact defining an “ideal observer.” But widespread (...) as this viewpoint is, it directly contradicts Bayesian philosophy of probability, which views probabilities as degrees of belief rather than relative frequencies, and explicitly denies that they are objective characteristics of the world. Moreover, tuning the prior to observed environmental frequencies is subject to overfitting, meaning in this context overtuning to the environment, which leads (ironically) to poor performance in future encounters with the same environment. Whenever there is uncertainty about the environment—which there almost always is—an agent's prior should be biased away from ecological relative frequencies and toward simpler and more entropic priors.

I argue that the standard way of formalizing the fine-tuning argument for design is flawed, and I present an alternative formalization. On the alternative formalization, the existence of life is not treated as the evidence that confirms design; instead it is treated as part of the background knowledge, while the fact that fine tuning is required for life serves as the evidence. I argue that the alternative better captures the informal line of thought that gives the fine-tuning (...) argument its intuitive plausibility, and I show that the alternative formalization avoids all of the most prominent objections to the fine-tuning argument, including the objection from observation selection effects, the problem of old evidence, the problem of non-normalizable probability measures and a further objection due to Monton. I conclude that the alternative formalization is the one that attention should be focused on. (shrink)

Does the fine-tuning of the universe for life continue in the afterlife? Aquinas would answer yes. In his view, the cosmic conditions post-apocalypse are set to support the resurrected body and the sensible knowledge of God’s majesty as reflected in the renewed material creature. The renewed universe is, thus, fine-tuned for immortal human life. In the first part, I present Aquinas’ version of fine-tuning, referring to earthly life and the afterlife. I distinguish between two modes of fine-tuning: (...) organic and cognitive. In the second part, I analyze the characteristics of the universe post-apocalypse in connection with the resurrected body in general and the qualities of the blessed body in particular. (shrink)

ExtractGottfried Wilhelm Leibniz was quite a thinker. As a philosopher, he made major contributions to epistemology, logic, the philosophy of religion and metaphysics. He was also an accomplished scientist, historian, and linguist. In mathematics, he built the first calculating machine able to perform all four elementary arithmetical operations, and devised the first proper formulation of binary numbers. Although Chinese and Indian scholars had developed several types of rudimentary binary notation centuries earlier, the number system at the heart of every modern (...) computer was put together by Leibniz. As if that were not enough to guarantee his immortality, he also developed calculus independently of Isaac Newton, and it is mostly Leibniz's version that survives in our textbooks, due to his superior notation.Send article to KindleTo send this article to your Kindle, first ensure [email protected] is added to your Approved Personal Document E-mail List under your Personal Document Settings on the Manage Your Content and Devices page of your Amazon account.

Starting from the late Renaissance, efforts to make vocal music more expressive heightened the power of words, which, in turn, gave birth to the modern semantics of musical expression. As the skepticism of seventeenth-century science divorced the acoustic properties from the metaphysical qualities of music, the door was opened to dicern the rich links between musical perception and varied mental faculties. In Tuning the Mind, Ruth Katz and Ruth HaCohen trace how eighteenth century theoreticians of music examined anew the (...) role of the arts within a general theory of knowledge. As the authors note, the differences between the physical and emotional dimensions of music stimulated novel conceptions and empirical inquiries into the old aesthetic queries. Tracing this development, their opening chapter deals with seventeenth-century epistemological issues concerning the artistic qualities of music. Katz and HaCohen show that painting and literature displayed a comparable tendency toward "musicalization," whereby the dynamic of forms-the modalities specific to each artistic medium-rather than subject matter was believed to determine expression. Katz and HaCohen explore the ambiguities inherent in idealization of an art form whose mimetic function has always been problematic. They discuss the major outlines of this development, from Descartes to Vico through Condillac. Particular emphasis is placed on eighteenth-century British thinkers, from Shaftesbury to Adam Smith, who perceived these problems in their full complexity. They also explore how the French and the Germans dealt differently with questions that preoccupied the British, each nation in accordance with their own past tradition and tendencies. The concluding chapter summarizes the parallel development of abstract art and basic hypotheses concerning the mind and explores basic theoretical questions pertaining to the relationship between perception and cognition. In addressing some of the most complex problems in musical aesthetics, Katz and HaCohen provide a unique historical perspective on the ways their art creates and develops coherent worlds, and, in so doing, contribute to our understanding of the workings of the mind. Ruth Katz is Emanuel Alexandre Professor of Musicology at the Hebrew University in Jerusalem. She is co-editor with Carl Dahlhaus of Contemplating Music, a four-volume study of the philosophy of music. Ruth HaCohen is Clarica and Fred Davidson Senior Lecturer of Musicology at the Hebrew University. (shrink)

Collins (The Blackwell companion to natural theology, 2009) presents an argument he calls the ‘core fine-tuning argument’. In this paper, I show that Collins’ argument is flawed in at least two ways. First, the structure, depending on likelihoods, fails to establish anything about the posterior probability of God’s existence given fine-tuning. As an argument for God’s existence, this is a serious failing. Second, his analysis of what is appropriately restricted background knowledge, combined with the credences of a specially (...) chosen ‘alien’, do not allow him to establish the premise \( \Pr (LPU \mid NSU~ \& ~k') \ll 1\).

The objective of this paper is analyzing to which extent the multiverse hypothesis provides a real explanation of the peculiarities of the laws and constants in our universe. First we argue in favor of the thesis that all multiverses except Tegmark’s “mathematical multiverse” are too small to explain the fine tuning, so that they merely shift the problem up one level. But the “mathematical multiverse" is surely too large. To prove this assessment, we have performed a number of experiments (...) with cellular automata of complex behavior, which can be considered as universes in the mathematical multiverse. The analogy between what happens in some automata (in particular Conway’s “Game of Life") and the real world is very strong. But if the results of our experiments can be extrapolated to our universe, we should expect to inhabit—in the context of the multiverse—a world in which at least some of the laws and constants of nature should show a certain time dependence. Actually, the probability of our existence in a world such as ours would be mathematically equal to zero. In consequence, the results presented in this paper can be considered as an inkling that the hypothesis of the multiverse, whatever its type, does not offer an adequate explanation for the peculiarities of the physical laws in our world.

This paper seeks to explicate and analyze an alternative response to fine-tuning arguments from those that are typically given—namely, design or brute contingency. The response I explore is based on necessity, the necessitarian response. After showing how necessity blocks the argument, I explicate the reply I claim necessitarians can give and suggest how its three requirements can be met: firstly, that laws are metaphysically necessary; secondly, that constants are metaphysically necessary; and thirdly, that the fundamental properties that determine the (...) laws and constants are necessary. After discussing each in turn, I end the paper by assessing how the response fares when running the fine-tuning argument in two ways, as an inference to best explanation and as a Bayesian argument.

Does the evidence that our universe contains fine-tuned life confirm the multiverse hypothesis? The answer depends on our approach to self-locating beliefs. In a recent paper, Isaacs, Hawthorne, and Russell (2022) offer two arguments for thinking that such evidence does confirm the multiverse hypothesis. First, they argue that the three leading approaches to self-locating beliefs all entail that such evidence confirms the multiverse hypothesis. Second, they present a pair of theorems showing that any approach to self-locating beliefs that satisfies certain (...) “reasonable” constraints will entail that such evidence confirms the multiverse hypothesis. I argue that Isaacs, Hawthorne, and Russell’s two arguments are not compelling, the first because they fail to consider some natural approaches to self-locating beliefs, the second because their theorems rely on a suspect premise that we should reject. Contra Issacs, Hawthorne, and Russell, I argue that on a natural approach to self-locating beliefs the evidence that our universe contains fine-tuned life needn’t confirm the multiverse hypothesis.

I present and defend an “indexical” version of the Fine-Tuning Argument. I begin by outlining the dialectic between the Fine-Tuning Argument, the Multiverse Objection, and the This-Universe Reply. Next, I sketch an indexical fine-tuning argument and defend it from two new objections. Then, I show that such an argument is immune to the Multiverse Objection. I explain how a further augmentation to the argument allows it to avoid an objection I call the “Indifference Objection.” I conclude that (...) my indexical version of the Fine-Tuning Argument is no less cogent than the standard version, and yet it is immune to the Multiverse Objection.

Fine-tuning in physics and cosmology is often used as evidence that a theory is incomplete. For example, the parameters of the standard model of particle physics are “unnaturally” small, which has driven much of the search for physics beyond the standard model. Of particular interest is the fine-tuning of the universe for life, which suggests that our universe’s ability to create physical life forms is improbable and in need of explanation, perhaps by a multiverse. This claim has been (...) challenged on the grounds that the relevant probability measure cannot be justified because it cannot be normalized, and so small probabilities cannot be inferred. We show how fine-tuning can be formulated within the context of Bayesian theory testing in the physical sciences. The normalizability problem is seen to be a general problem for testing any theory with free parameters, and not a unique problem for fine-tuning. Physical theories in fact avoid such problems in one of two ways. Dimensional parameters are bounded by the Planck scale, avoiding troublesome infinities, and we are not compelled to assume that dimensionless parameters are distributed uniformly, which avoids non-normalizability.

Fine-tuning arguments are a frequent find in the literature on quantum field theory. They are based on naturalness—an aesthetic criterion that was given a precise definition in the debates on the Higgs mechanism. We follow the history of such definitions and of their application at the scale of electroweak symmetry breaking. They give rise to a special interpretation of probability, which we call Gedankenfrequency. Finally, we show that the argument from naturalness has been extended to comparing different models of (...) the physics beyond the Standard Model and that naturalness in this case can at best be understood a socio-historic heuristic.

According to the Fine-Tuning Argument, the existence of life in our universe confirms the Multiverse Hypothesis. A standard objection to FTA is that it violates the Requirement of Total Evidence. I argue that RTE should be rejected in favor of the Predesignation Requirement, according to which, in assessing the outcome of a probabilistic process, we should only use evidence characterizable in a manner available before observing the outcome. This produces the right verdicts in some simple cases in which RTE (...) leads us astray, and, when applied to FTA, it shows that our evidence does confirm HM. (shrink)

Caregivers’ language input supports children’s language development, and it is often tuned to the child’s current level of skill. Evidence suggests that parental input is tuned to accommodate children’s expressive language levels, but accommodation to receptive language abilities is less understood. In particular, little is known about parental sensitivity to children’s abilities to process language in real time. Compared to nonspectrum children, children on the spectrum are slower to process language. In this study, we ask: Do parents of autistic children (...) and those of nonspectrum children tune their language input to accommodate children’s different language processing abilities? Children with and without a diagnosis of autism and their parents viewed a display of six images, one of which was the target. The parent labeled the target to direct the child’s attention to it. We first examined children’s language processing abilities by assessing their latencies to shift gaze to the labeled referent; from this, we found slower latencies in the autistic group than in the nonspectrum group, in line with previous findings. We then examined features of parents’ language and found that parents in both groups produced similar language, suggesting that parents may not adjust their language input according to children’s speed of language processing. This finding suggests that capturing parental sensitivity to children’s receptive language, and specifically language processing, may enrich our models of individual differences in language input, and future work should investigate if supporting caregivers in tuning their language use according to children’s language processing can improve children’s language outcomes.

Different human practices require various methods to carry them out successfully. Philosophy, an activity with 2500 years of history, must also have its own method, which demarcates a philosopher from a lay person. This thesis embarks on a project of philosophical method—conceptual tuning. How to do philosophy belongs to the category of metaphilosophy or philosophy of philosophy. Boxers usually do not care about the conceptual question ‘What is boxing?’ and biologists barely ask ‘What is Biology?’. For them, this kind (...) of question is a higher order question which concerns the nature of the thing in itself. It is an external question for most disciplines. But for philosophy, the question concerning the nature of philosophy is an internal question. Self-awareness is a sine qua non of doing philosophy.With such a long history and so many traditions, the method of doing philosophy must be miscellaneous. My thesis attempts to contribute to the discussion of philosophical methodology by proposing a method I shall call conceptual tuning. Conceptual tuning is grounded in the philosophical method of conceptual engineering, advocates of which endeavor to improve our concepts. According to the method of conceptual engineering, philosophical problems stem from defects in our understanding of concepts, and it is the philosopher’s task to fix them. While most conceptual engineering approaches only narrowly focus on the perspective of ‘repairing’ or ‘fixing’, conceptual tuning calls for attention to the ‘expressive’ perspective. In other words, we should put this method in the broad framework of the practice of asking for and giving reasons. In this thesis, I also attempt to explain some previous conceptual methods under the title of conceptual tuning, such as Brandomian method, ordinary language philosophy, and the traditional conceptual analyses.

Emotionally arousing events reach awareness more easily and evoke greater visual cortex activation than more mundane events. Recent studies have shown that they are also perceived more vividly and that emotionally enhanced perceptual vividness predicts memory vividness. We propose that affect-biased attention (ABA) – selective attention to emotionally salient events – is an endogenous attentional system tuned by an individual's history of reward and punishment. We present the Biased Attention via Norepinephrine (BANE) model, which unifies genetic, neuromodulatory, neural and behavioural (...) evidence to account for ABA. We review evidence supporting BANE's proposal that a key mechanism of ABA is locus coeruleus–norepinephrine (LC–NE) activity, which interacts with activity in hubs of affective salience networks to modulate visual cortex activation and heighten the subjective vividness of emotionally salient stimuli. We further review literature on biased competition and look at initial evidence for its potential as a neural mechanism behind ABA. We also review evidence supporting the role of the LC–NE system as a driving force of ABA. Finally, we review individual differences in ABA and memory including differences in sensitivity to stimulus category and valence. We focus on differences arising from a variant of the ADRA2b gene, which codes for the alpha2b adrenoreceptor as a way of investigating influences of NE availability on ABA in humans. (shrink)

Whether visual perceptual consciousness is gradable or dichotomous has been the subject of fierce debate in recent years. If perceptual consciousness is gradable, perceivers may have less than full access to—and thus be less than fully phenomenally aware of—perceptual information that is represented in working memory. This raises the question: In virtue of what can a subject be less than fully perceptually conscious? In this chapter, we provide an answer to this question, according to which inexact categorizations of visual input (...) may result in a representation of the visual information in working memory that is less than fully available to the perceiver, and of which the perceiver is therefore less than fully phenomenally aware. The latter proposal is a natural extension of a theory of perception we have proposed in previous works, namely, the template tuning theory (TTT). We argue that although TTT is compatible with both gradable and dichotomous conceptions of perceptual consciousness, the available empirical evidence favours a gradable conception of perceptual consciousness.

In this paper, I propose that, in addition to the multiverse hypothesis, which is commonly taken to be an alternative explanation for fine-tuning, other than the design hypothesis, the simulation hypothesis is another explanation for fine-tuning. I then argue that the simulation hypothesis undercuts the alleged evidential connection between ‘designer’ and ‘supernatural designer of immense power and knowledge’ in much the same way that the multiverse hypothesis undercuts the alleged evidential connection between ‘fine-tuning’ and ‘fine-tuner’ (or ‘designer’). (...) If this is correct, then the fine-tuning argument is a weak argument for the existence of God. (shrink)

Force strengths, particle masses, etcetera, appear "fine tuned" for intelligent life. There may be many very diverse universes, observational selection explaining why we see a life-permitting one. The alternative is divine selection. The God hypothesis can explain how one and the same force strength or particle mass satisfies life’s many different requirements, and why there are life-encouraging laws of relativity and of quantum theory. It could also answer why any universe exists. God’s existence could be accounted for Platonically, by its (...) ethical requiredness. The most plausible world-view would then be Spinozistic, on lines explored in my recent book "Infinite Minds". (shrink)

Proponents of the Fine-Tuning Argument frequently assume that the narrowness of the life-friendly range of fundamental physical constants implies a low probability for the origin of the universe ‘by chance’. We cast this argument in a more rigorous form than is customary and conclude that the narrow intervals do not yield a probability at all because the resulting measure function is non-normalizable. We then consider various attempts to circumvent this problem and argue that they fail.

In engineering, as in other scientific fields, researchers seek to confirm their models with real-world data. It is common practice to assess models in terms of the distance between the model outputs and the corresponding experimental observations. An important question that arises is whether the model should then be ‘tuned’, in the sense of estimating the values of free parameters to get a better fit with the data, and furthermore whether the tuned model can be confirmed with the same data (...) used to tune it. This dual use of data is often disparagingly referred to as ‘double-counting’. Here, we analyse these issues, with reference to selected research articles in engineering. Our example studies illustrate more and less controversial practices of model tuning and double-counting, both of which, we argue, can be shown to be legitimate within a Bayesian framework. The question nonetheless remains as to whether the implied scientific assumptions in each case are apt from the engineering point of view. (shrink)

The universe appears fine-tuned for life. Bayesian confirmation theory is utilized to examine two competing explanations for this fine-tuning, namely design (theism) and the existence of many universes, in comparison with the ’null’ hypothesis that just one universe exists as a brute fact. Some authors have invoked the so-called ’inverse gambler’s fallacy’ to argue that the many-universes hypothesis does not explain the fine-tuning of ’this’ universe, but flaws in this argument are exposed. Nevertheless, the hypothesis of design, being (...) simpler, is arguably of higher prior probability and, therefore, to be preferred. The hypothesis of the single brute-fact universe is disconfirmed.

The Myopic Anthropic Principle: an attempt to show that the popular anthropic reasoning of our time — often taken to show that laws of nature are fine-tuned by a god for us — should be seen merely as an indication of fine-tuning by us. This preference for short-sightedness in this case is shown (shown?) to support the best-system account of scientific law.

Long‐term potentiation (LTP) of excitatory synapses is a leading model to explain the concept of information storage in the brain. Multiple mechanisms contribute to LTP, but central amongst them is an increased sensitivity of the postsynaptic membrane to neurotransmitter release. This sensitivity is predominantly determined by the abundance and localization of AMPA‐type glutamate receptors (AMPARs). A combination of AMPAR structural data, super‐resolution imaging of excitatory synapses, and an abundance of electrophysiological studies are providing an ever‐clearer picture of how AMPARs are (...) recruited and organized at synaptic junctions. Here, we review the latest insights into this process, and discuss how both cytoplasmic and extracellular receptor elements cooperate to tune the AMPAR response at the hippocampal CA1 synapse.

Many theists regard the claim that certain fundamental constants of nature are fine-tuned for life as the best scientific argument for the existence of God since Paley’s watch. Even atheist physicists find these so-called “anthropic coincidences” difficult to explain naturally and many think they need to invoke multiple universes and the so-called “anthropic principle” to do so. Certainly if there are many universes, fine-tuning is simple. Our universe is not fine-tuned for life. Life is fine-tuned to our universe. While (...) multiple universes are expected from modern cosmological theories, theists and some scientists object that invoking the unobservable is not science. Of course, God is unobservable too, so the best theists can claim is a standoff. (shrink)

Can a set of musical metaphors in a treatise on ethics reveal something about the nature and source of moral autonomy? This article argues that it can. It shows how metaphorical usage of words like tone, pitch, and concord in Adam Smith's Theory of Moral Sentiments can be understood as elements of an analogical model for morality. What this model tells us about morality depends on how we conceptualise music. In contrast to earlier interpretations of Smith's metaphors that have seen (...) music as an aesthetic object, this article sees music as a practice. Understood in this way, the analogy allows us to see morality too as a practice––as moral tuning. This in turn reveals a novel answer to the intractable problem of conventionalism: moral autonomy consists in the freedom inherent in the constant need to interpret and reinterpret the strictly formal ideal of perfect propriety.
