Two variables are usually recognised as determinants of human causal learning: the contingency between a candidate cause and effect, and the temporal and/or spatial contiguity between them. A common finding is that reductions in temporal contiguity produce concomitant decrements in causal judgement. This finding had previously (Shanks & Dickinson, 1987) been interpreted as evidence that causal induction is based on associative learning processes. Buehner and May (2002, 2003, 2004) have challenged this notion by demonstrating that the impact of temporal delay (...) depends on expectations about the timeframe between cause and effect. A corollary of this knowledge-mediation account is that in certain situations longer delays could facilitate, while shorter delays should impair, causal learning. Here we present two experiments involving a physical apparatus that demonstrate a detrimental effect of contiguity under certain conditions. In contrast to all previous studies, delays universally promoted causal learning. This evidence is clearly at variance with the notion of a bottom-up contiguity bias in causal induction. A new, more general timeframe bias is discussed. (shrink)

In order to improve our understanding of the components that reflect functionally important processes during reward anticipation and consumption, we used principle components analyses (PCA) to separate and quantify averaged ERP data obtained from each stage of a modified monetary incentive delay (MID) task. Although a small number of recent ERP studies have reported that reward and loss cues potentiate ERPs during anticipation, action preparation, and consummatory stages of reward processing, these findings are inconsistent due to temporal and spatial overlap (...) between the relevant electrophysiological components. Our results show three components following cue presentation are sensitive to incentive cues (N1, P3a, P3b). In contrast to previous research, reward‐related enhancement occurred only in the P3b, with earlier components more sensitive to break‐even and loss cues. During feedback anticipation, we observed a lateralized centroparietal negativity that was sensitive to response hand but not cue type. We also show that use of PCA on ERPs reflecting reward consumption successfully separates the reward positivity from the independently modulated feedback‐P3. Last, we observe for the first time a new reward consumption component: a late negativity distributed over the left frontal pole. This component appears to be sensitive to response hand, especially in the context of monetary gain. These results illustrate that the time course and sensitivities of electrophysiological activity that follows incentive cues do not follow a simple heuristic in which reward incentive cues produce enhanced activity at all stages and substages.

L'interprétation de l'eschatologie paulinienne est dominée par la question de son rapport avec l'apocalyptique juive. Les points communs, soulignés par J.C. Beker à la suite de E. Käsemann, ne sont pas contestables, mais ne doivent pas occulter des différences notables, qui tiennent à la prééminence du Christ dans la vision paulinienne des événements de la fin. Ni l'attente ni le retard de la parousie ne semblent avoir eu, quoi qu'on en dise, d'influence décisive sur la pensée de l'Apôtre, mais bien (...) plutôt la réconciliation avec Dieu par la Croix et l'inauguration d'une humanité nouvelle dans la résurrection du Christ.Les lettres deutéropauliniennes ne rnodifient pas fondamentalement cette eschatologie, si ce n'est qu'elles accentuent encore l'emprise de la christologie sur la vision de la fin : à ceux qui attendent les ascensions célestes promises par la littérature apocalyptique, Paul répond qu'ils possèdent déjà leur être ressuscité avec le Christ, qui trône bien au-dessus de tous les être célestes. Ses idées sur le jugement dernier et la rétribution finale sont parfois dépendantes de celles du judaïsme, souvent imprécises et limitées, mais c'est toujours sa connaissance du Ressuscité, second Adam, qui conduit sa réflexion et l'aide à déchiffrer le destin final de l'humanité dans le Christ. The interpretation of pauline eschatology is dominated by the question of its rapport with Jewish apocalypse. The common points, underlined by J.C. Beker following E. Käsemann, cannot be contested, but should not hide the notable differences, which are based on the pre-eminence of Christ in the Pauline vision of the final events. Neither the expectation nor the delay of the Parousia does not seem to have had, despite what is said, a decisive influence on the Apostle’s thinking. He was concerned more about reconciliation with God through the cross and the inauguration of a new humanity by the resurrection of Christ.The deuteropauline letters do not fundamentally modify this eschatology, except in so far as they accentuate the dominance of Christology on the vision of the end. For those who await the celestial ascensions promised by apocalyptic literature, Paul answers that they already possess their resurrected being with Christ, who sits well above are celestial beings. These ideas on the Last Judgement and the final retribution are sometimes dependent on those of Judaism, often imprecise and limited, but it is always Paul's knowledge of the Resurrected, the second Adam, which directs his reflection and helps to decipher the final destiny of humanity in Christ.

The aim of the My Character project was to develop a better understanding of how interventions designed to develop character might enhance moral formation and futuremindedness in young people. Futuremindedness can be defined as an individual’s capacity to set goals and make plans to achieve them. Establishing goals requires considerable moral reflection, and the achievement of worthwhile aims requires character traits such as courage and the capacity to delay gratification. The research team developed two new educational interventions – a website (...) and a hard-copy journal – with the specific aim of developing future-mindedness. After development, the website and journal were piloted over a one-year period by over 1,000 11–14 year olds in six schools across England. Various research methods, including group interviews and case studies, were implemented to assess impact. In addition, a pilot RCT was conducted to assess the feasibility of using experimental methods to measure character. The main findings from the research are that: - Students benefit from opportunities in school to think about future-mindedness; this can be successfully taught through character education. - Harnessing new technology, such as the Internet, offers exciting opportunities for character education. - It is beneficial to investigate the impact of new character education resources in order to bring greater clarity about ‘what works’. The most useful approach is a mixed methods one that allows for triangulation of evidence. - It is possible to run RCTs and other experimental research in schools to assess developmental projects of this kind, but applying the method in schools and creating suitable outcome measures present challenges for researchers. - A positive indicator of the success is that five out of the six pilot schools have embedded My Character into their curriculum. In addition, many new schools, both in Britain and internationally, have started to use the website and / or journal. This report describes the research, analyses the impact of My Character and concludes with recommendations for policy makers, practitioners and researchers embarking on similar projects. These recommendations include: i) advocating that schools create space in the curriculum to teach future-mindedness through character education; ii) enhancing traditional character education teaching methods with opportunities brought by Internet technologies; iii) evaluating character education interventions using triangulated evidence drawn from a mixture of research methods.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:An Exposition of The Divine Names, The Book of Blessed Dionysius by Thomas AquinasMichael J. Rubin, Elizabeth C. Shaw, and Staff*AQUINAS, Thomas. An Exposition of The Divine Names, The Book of Blessed Dionysius. Translated and edited with an introduction by Michael A. Augros. Merrimack, N.H.: Thomas More College Press, 2021. xxv + 549 pp. Cloth, $65.00The profound influence that Pseudo-Dionysius had on Aquinas’s thought, especially in his metaphysics (...) of participation and his apophatic theology, has been known for some time now, thanks to the excellent work of such scholars as Fran O’Rourke. One would therefore think that Aquinas’s Exposition of the Divine Names (his only commentary on the works of Pseudo-Dionysius) would have been translated a lot sooner. This delay is assuredly due not just to the difficulty of translating this work but also to a certain embarrassment felt by Thomists over Aquinas’s sincere belief that the “Dionysius” who wrote the Divine Names was the Areopagite whose conversion at the teaching of St. Paul is mentioned in the Acts of the Apostles. That the author calling himself “Dionysius” was in fact a theologian writing in the fifth or sixth centuries has been well established by modern scholarship. Hence, Thomists may have felt tempted to discount or at least pass over the influence of this author on Aquinas since it is discomfiting to think that the Church’s greatest theologian accorded such authority to an imposter.Michael Augros tackles these concerns head-on in the excellent introduction to his new translation of the Divine Names commentary. First, Augros points out that in past centuries a pseudonym was usually not an act of forgery but, rather, a way of concealing the author’s identity, which an early Christian theologian might well decide to do either out of humility or out of a desire “to avoid provoking certain prejudices” in those who disagreed with him in contemporary theological disputes. Moreover, it is likely that the work was never intended for the general public (who could easily mistake the pseudonym as genuine) but, rather, was written for those “already initiated in a particular Neoplatonic school of Christian theology,” who would recognize the author as being “one of their own” but without knowing his precise identity. Finally, in taking the particular name of “Dionysius,” the author of the Divine Names was indicating his intention for the work: Just as the biblical Dionysius was a Greek philosopher who converted to Christianity, so the works of Pseudo-Dionysius [End Page 345] are an attempt to reconcile Greek philosophy with the Christian faith.It therefore seems likely, as Augros observes, that Aquinas would still have accorded a great deal of respect to the Divine Names even if he had learned the truth of the author’s identity. The work would not have had the same deuterocanonical authority for him that comes with being written by a direct disciple of St. Paul himself, but “the inherent cogency, coherence, and beauty” of Pseudo-Dionysius’s theology would have been the same. Hence, Pseudo-Dionysius would surely have earned from Aquinas the “docile attitude” appropriate “for a philosopher and theologian of the first order, such as Boethius.”That Aquinas was right to see the author of the Divine Names as a master philosopher and theologian becomes evident when one dives into the text itself, in which Aquinas sees a truly dazzling order, both externally and internally. According to Aquinas, the Divine Names discusses those truths about God of which there are intelligible likenesses in creatures, such as goodness or wisdom, whereas the truths about God of which there are sensible likenesses (for example, “when God is called a lion, or a rock”) are treated by Pseudo-Dionysius in The Symbolic Theology; meanwhile, in the lost or fictional work The Divine Characteristics, Dionysius claims to have treated those truths about God (such as the Trinity) that cannot be known through any likenesses in creatures.Aquinas finds a still more intricate order within the Divine Names itself. Since this work is dedicated to “the divine names by which the processions of God to creatures are manifested,” the plan of the work... (shrink)

The neurophysiological evidence from the Miyashita group's experiments on monkeys as well as cognitive experience common to us all suggests that local neuronal spike rate distributions might persist in the absence of their eliciting stimulus. In Hebb's cell-assembly theory, learning dynamics stabilize such self-maintaining reverberations. Quasi-quantitive modeling of the experimental data on internal representations in association-cortex modules identifies the reverberations (delay spike activity) as the internal code (representation). This leads to cognitive and neurophysiological predictions, many following directly from the language (...) used to describe the activity in the experimental delay period, others from the details of how the model captures the properties of the internal representations.

Every infant has a right to bodily integrity. Removing healthy tissue from an infant is only permissible if there is an immediate medical indication. In the case of infant male circumcision there is no evidence of an immediate need to perform the procedure. As a German court recently held, any benefit to circumcision can be obtained by delaying the procedure until the male is old enough to give his own fully informed consent. With the option of delaying circumcision providing all (...) of the purported benefits, circumcising an infant is an unnecessary violation of his bodily integrity as well as an ethically invalid form of medical violence. Parental proxy ‘consent’ for newborn circumcision is invalid. Male circumcision also violates four core human rights documents—the Universal Declaration of Human Rights, the Convention on the Rights of the Child, the International Covenant on Civil and Political Rights, and the Convention Against Torture. Social norm theory predicts that once the circumcision rate falls below a critical value, the social norms that currently distort our perception of the practice will dissolve and rates will quickly fall.

The U.S. review system for human subjects research has been widely criticized in recent years for requirements that delay research without improving human subjects protections. Any major reformulation of regulations may take some time to implement. In the meantime, current regulations often allow for streamlined ethics review without jeopardizing—and possibly improving—protections for research participants. We discuss underutilized options, including research that need not be classified as “human subjects research,” categories of studies that can be exempt from ethical review, and studies (...) that need only undergo expedited review by one IRB member. In addition, we consider ways to simplify review of multi-center research using one institution’s IRB. We speculate on multiple reasons for the underuse of these mechanisms, and exhort IRBs and researchers to take advantage of these important opportunities to improve the review process. (shrink)

This chapter describes three relatively specific forms such as destructive uploading, gradual uploading, and nondestructive uploading. Neuroscience is gradually discovering various neural correlates of consciousness, but this research program largely takes the existence of consciousness for granted. It presents an argument for the pessimistic view and an argument for the optimistic view, both of which run parallel to related arguments that can be given concerning teletransportation. Cryonic technology offers the possibility of preserving our brains in a low‐temperature state shortly after (...) death, until such time as the technology is available to reactivate the brain or perhaps to upload the information in it. Reconstructive uploading from brain scans is closely akin to ordinary (nongradual) uploading from brain scans, with the main difference being the time delay, and perhaps the continued existence in the meantime of the original person.

How do humans discover causal relations when the effect is not immediately observable? Previous experiments have uniformly demonstrated detrimental effects of outcome delays on causal induction. These findings seem to conflict with everyday causal cognition, where humans can apparently identify long-term causal relations with relative ease. Three experiments investigated whether the influence of delay on adult human causal judgements is mediated by experimentally induced assumptions about the timeframe of the causal relation in question, as suggested by Einhorn and Hogarth (1986). (...) Causal judgements generally decreased when a delay separated cause and effect. This decrease was less pronounced when the thematic context of the causal relation induced participants to expect a delay. Experiment 3 ruled out an alternative explanation of the effect based on variations of cue and outcome saliencies, and showed that detrimental effects of delay are reduced even more when instructions explicitly mentioned the timeframe of the causal relation in question. Knowledge thus mediates the impact of delay on human causal judgement. Implications for contemporary theories of human causal induction are discussed. (shrink)

There is some complementarity of models for the origin of the electroencephalogram (EEG) and neural network models for information storage in brainlike systems. From the EEG models of Freeman, of Nunez, and of the authors' group we argue that the wavelike processes revealed in the EEG exhibit linear and near-equilibrium dynamics at macroscopic scale, despite extremely nonlinear – probably chaotic – dynamics at microscopic scale. Simulations of cortical neuronal interactions at global and microscopic scales are then presented. The simulations depend (...) on anatomical and physiological estimates of synaptic densities, coupling symmetries, synaptic gain, dendritic time constants, and axonal delays. It is shown that the frequency content, wave velocities, frequency/wavenumber spectra and response to cortical activation of the electrocorticogram (ECoG) can be reproduced by a “lumped” simulation treating small cortical areas as single-function units. The corresponding cellular neural network simulation has properties that include those of attractor neural networks proposed by Amit and by Parisi. Within the simulations at both scales, sharp transitions occur between low and high cell firing rates. These transitions may form a basis for neural interactions across scale. To maintain overall cortical dynamics in the normal low firing-rate range, interactions between the cortex and the subcortical systems are required to prevent runaway global excitation. Thus, the interaction of cortex and subcortex via corticostriatal and related pathways may partly regulate global dynamics by a principle analogous to adiabatic control of artificial neural networks.

We need to rethink our attitudes to the bodies of the dead in order to increase our willingness to donate organs and tissuesMy father died aged 87 on January 20, 1998. It was the day of his 42nd wedding anniversary. He been admitted to a major teaching hospital with jaundice of unknown origin. He died after a medical procedure and a delay in diagnosis and management of bleeding after the procedure. I believed it was important to understand why he had (...) died and what the underlying cause of his jaundice had been. I requested an autopsy.My father was not only the best father a person could have had, but my closest friend. The circumstances of his death were especially sad for me. I was on a plane while he was allowed to die of blood loss in intensive care over a period of hours, becoming progressively more delirious and experiencing the slow motion throes of death. I was told he had died while I was still in the air. My first thought was that I would never again see him or hear his deep chuckle. I would never again feel the gentle touch of his large hands. He would never see my daughter grow up as he had wanted to, playing, and laughing on the beach.I have witnessed many autopsies. As medical students, we had to attend autopsy each morning at 8.30 am as a part of pathology in fourth year medicine. Before this, we had two years of anatomy dissection, probing every crevice of the formalin fixed human body. I learnt an immense amount from these activities. But I also knew how gruesome the autopsy is. I knew that an autopsy would mean that my father would be dismembered. But I had no hesitation in requesting …. (shrink)

We consider the time delay of massive, non-relativistic, one-dimensional particles due to a tunneling potential. In this setting the well-known Hartman effect asserts that often the sub-ensemble of particles going through the tunnel seems to cross the tunnel region instantaneously. An obstacle to the utilization of this effect for getting faster signals is the exponential damping by the tunnel, so there seems to be a trade-off between speedup and intensity. In this paper we prove that this trade-off is never in (...) favor of faster signals: the probability for a signal to reach its destination before some deadline is always reduced by the tunnel, for arbitrary incoming states, arbitrary positive and compactly supported tunnel potentials, and arbitrary detectors. More specifically, we show this for several different ways to define “the same incoming state” and “the same detector” when comparing the settings with and without tunnel potential. The arrival time measurements are expressed in the time-covariant approach, but we also allow the detection to be a localization measurement at a later time. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:EPILOGUE Robert J. Daly, SJ. Boston College April 2002 Iwill arrange my comments under four headings: (1) what we had hoped to accomplish; (2) what we actually did accomplish; (3) what we may have learned from this; (4) what this might now enable us to do in thefuture. This epilogueisbeingwritten in April, 2002,twenty-twomonths after the conference. To draw what good we can from this delay, writing at this distance (...) allows me to summarize and draw conclusions with, perhaps, a bit more balance. On the other hand, my listening again to the audio record in the course ofpreparing this publication has enabled me to relive something of the original experience. (1)As I indicated in the introduction, we had unrealistically hoped that, by the time ofthe conference, the five presenters, and perhaps also the twoprincipals inthe "Girard-Lonergan Conversation," wouldhavealready exchanged with each other not just first drafts, but even second drafts of their papers, and that the conference itself would then be invited to join a conversation that was already well under way. As it turned out, I couldn't muster the organizational skills and resources needed to achieve this. But reflecting after the fact, I can see that so carefully detailed a preparation might have been counterproductive. Carrying out our original plan might have been at the cost ofimposing more ofa Western analytic pattern on our discussion ofother traditions, and of!thus smothering from the outset some of the insight that did occur. We had also hoped that the opening "Girard-Lonergan Conversation" would provide an analytic resource for the rest of the meeting. But that did not happen to any great extent. (2)The proximate preparation for this conference began with a draft version ofmy paper being sent to the other major presenters. I opened with 194Robert J. Daly, SJ. a series of brief sketches of salient points in the often unhappy but also occasionally felicitous history ofChristianity on this theme ofviolence and institution. Then, after emphasizing the importance of distinguishing between the normative and the descriptive, I tried to make some sense, both rational and theological, of all this data, especially by reflecting on the influences and consequences ofthe belief in hell, on the one hand, and the hope of universal salvation, on the other. The next major religious theme was Judaism. Reuven Kimelman provided a detailed—and, for some, overwhelming—glimpse of the way the talmudic traditions deal with the theme of war and its restrictions. This highly text-oriented and interpretation-of-texts driven presentation seemed to many, at first, to be irrelevant to mimetic theory and to the need to be confronting actual violence. But, in the course of Sandor Goodhart's response, and in the course ofthe at times spirited discussion that followed, we began to understand that how one interprets texts and traditions, and how these are played off against each other, is indeed fundamental to the way Jews typically try to deal with the practical challenges of violence. Qamar-ul Huda's presentation on IsIamfocused stronglyonthe way the spiritual teachings of Islam—i.e., islam as a religion rather than Islam as a political or national institution—foster peace. The initial reaction was somewhat similarto the reaction to Kimelman's paper: disappointment that Huda was not talking more directly about contemporary Muslim extremist violence. But here, too, the discussion enabled us to catch a glimpse both of the inner spiritual resources of Islam, and of the limitations ofthe range of concerns that Westerners typically bring to the table. Francis Clooney, in his presentation ofHinduism, strongly emphasized the great variety in Hinduism, stressing that one cannot speak ofHinduism as such. Much of this variety comes from the several millennia of Hindu history, and from the complex relationships to Buddhism and Jainism which, themselves, are important parts of Hindu history, and also from the fact that only recently have Hindus, after centuries of Moslem or Colonial domination, once again returned to positions of political and military power. Finally, Christopher Ives's presentation on Buddhism, in a way similar to my presentation on Christianity, but more extensively or more consequently, pointed out the various ways in which Buddhism has been politically and...

Extrinsic mortality is a key influence on organisms’ life history strategies, especially on age at maturity. This historical longitudinal study of 125 women in rural Domenica examines effects of extrinsic mortality on human age at maturity and pace of reproduction. Extrinsic mortality is indicated by local population infant mortality rates during infancy and at maturity between the years 1925 and 2000. Extrinsic mortality shows effects on age at first birth and pace of reproduction among these women. Parish death records show (...) huge historical variation in age-specific mortality rates. The infant mortality rate (IMR) in the early 1920s was low, increased dramatically beginning in 1929, and reached a maximum in the 1950s, at which point IMR declined steadily to its present low rate. The mortality rate early in life showed a quadratic association with age at first birth. Women who experienced conditions of low IMR early in life reproduced relatively late in life. Those born into moderately high levels of infant mortality tended to reproduce earlier than those born at low levels. At very high infant mortality levels early in life, women went on to delay reproduction until relatively late, possibly as a result of somatic depletion and energetic stress associated with the conditions that lead to high IMR. Population mortality rates at age of maturity also showed a quadratic association with age at first birth. The pace of reproduction, estimated as number of surviving offspring controlled for maternal age, showed a similar quadratic effect. There were complex interactions between population mortality rates in infancy and at maturity. When extrinsic mortality was high during infancy, extrinsic mortality later in life had little effect on timing of first birth. When extrinsic mortality was low to moderate in infancy, extrinsic mortality later in life had significant effects on adult reproduction. I speculate that these effects are mediated through development of personality facets associated with reproduction. (shrink)

The female reproductive axis in mammals is a highly complex dynamic system which goes through different transient or absorbent states during the course of a life-time. Little is known about the mechanisms controlling this system during fetal life and at birth, although it has been shown in numerous species, including primates, that the whole machinery is already functioning . After a delay ranging from a few days to a few weeks, according to the species, the reproductive axis becomes quiescent and (...) activity apparently resumes only at the time of puberty. Here again understanding of the phenomenon is still limited. (shrink)

ABSTRACT:Officials must understand why and how the public lost confidence in the federal government’s ability to manage financial turmoil. Officials outsourced to private parties responsibility for monitoring and policing the safety-net exposures that were bound to be generated by weaknesses in the securitization process. When the adverse consequences of this imprudent arrangement first emerged, officials claimed for months that the difficulties that short-funded, highly leveraged firms were facing in rolling over debt reflected only a shortage of aggregate liquidity and not (...) individual-firm shortages of economic capital. Then, in September 2008, the president and other officials created an unwise sense of urgency that delays in implementation show to have been greatly exaggerated.That authorities and financiers violated common-law duties of loyalty, competence, and care they owe to taxpayers indicates a massive incentive breakdown in industry and government. Taxpayers deserve a thorough-going reorientation of: (1) how regulatory agencies report on their regulatory performance and back-room interactions with Congress and the Treasury, and (2) the contract structures and performance measures used by the financial industry and its government overseers.

In spite of its commercial importance and signs of clear concern in public policy arenas, trade credit has not been subjected to systematic, extended analysis in the business ethics literature, even where suppliers as a stakeholder group have been considered. This paper makes the case for serious consideration of the ethics of trade credit and explores the issues surrounding slow payment of debts. It discusses trade debt as a kind of promise, but—noting that not all promises are good ones—goes on (...) to develop an analysis of the ethics of trade credit grounded in an understanding of its fundamental purpose. Making a distinction between “operating” trade credit and “financial” trade credit, the paper provides an account of the maximum period for which it is appropriate for one company to delay payment to another from which it has purchased goods or services. The concern of commentators and policy makers that companies should not take too long to pay their debts is affirmed, but the understanding of what timely payment means is significantly finessed, with one conclusion being that, if debts have not already been settled according to acceptable standard terms of trade, cash should pass quickly back along the supply chain once the customer in the final product market has paid. The analysis has implications not only for companies that take credit but also for external parties that seek to rate companies or set regulations according to speed of payment—an approach that is shown to be misleadingly simplistic, albeit well intentioned. A corresponding important responsibility for suppliers, not to extend excessive credit, also follows from the analysis developed. Having provided a novel analysis of an important business problem, the paper then discusses some of the related practical issues and makes suggestions for further research. (shrink)

The context of the target article is delimited again, underlining the intended locationof the argument in the bottomup hierarchy of brain study. The central message is that collective delay activity distributions (reverberations) in cortical modules extend the role of a spike (a potentialinformation carrier across long distances) to an active memory of structured, learned information that can be carried across long time intervals. Moreover, the population code of the reverberations makes them readable down the cortical processing stream. Most of the (...) critical comments are then interpreted and addressed in relation to misreading of the proper context. The price for the limitation of the context (in cognitive, behavioral, and computational terms) is compared with the advantages of a clear, direct contact with experiment on the one hand and with a well controlled body of modeling and analysis on the other.

Einstein proclaimed that we could discover true laws of nature by seeking those with the simplest mathematical formulation. He came to this viewpoint later in his life. In his early years and work he was quite hostile to this idea. Einstein did not develop his later Platonism from a priori reasoning or aesthetic considerations. He learned the canon of mathematical simplicity from his own experiences in the discovery of new theories, most importantly, his discovery of general relativity. Through his neglect (...) of the canon, he realised that he delayed the completion of general relativity by three years and nearly lost priority in discovery of its gravitational field equations.
