If we suppose that reasonable belief is reasonable not because it has a foundation but because it is self-correcting, and that bodies of reasonable belief are self-correctable in virtue of their web-like internal structure, then it becomes natural to ask for explicit accounts both of self-correction itself, and of the web-like internal structure that makes self-correction possible: The theory of rational belief change. ;In this essay we study qualitative, logical theories of rational belief change, in particular (...) the AGM account, and its offshoot, the theory base account. Throughout, however, we use quantitative, probabilistic models as foils. ;We first undertake a systematic, critical study of the AGM account, focusing especially on its "possible worlds" formulation and on its theory of belief revision. According to the AGM account we can represent AGM revision by simple computations over total preorders of possibilities. We investigate iterated AGM revision from this perspective, and prove that symmetry considerations familiar from social choice theory essentially determine a particular ordering dynamics. These symmetry arguments put an upper bound on the sorts of responsiveness we can expect from the AGM model of rational belief change. The most widely criticized feature of the AGM account is its "recovery" condition on belief contraction. We show how to deflect all existing criticisms to recovery by paying close to attention to exactly which beliefs are given up in a particular case. The principal cost of this strategy is that the AGM account becomes harder to apply and to test. ;Theory base accounts add a layer of syntactically-encoded information to the AGM model. We show that this approach fails comprehensively: that it cannot successfully coordinate the syntactic layer of information with underlying contents or with necessary ordering information, and that it sanctions demonstrably irrational belief changes. Our diagnosis is, in part, that the theory base account conflates two distinct sorts of nonmonotonic belief change. ;Lastly, we summarize our current research into quantitative accounts of rational belief change, focusing on a model that generalizes irreducibly two-place probability, and that has the AGM account as a limiting case.

A popular and plausible response against Laudan's “pessimistic induction” has been what I call “preservative realism,” which argues that there have actually been enough elements of scientific knowledge preserved through major theory‐change processes, and that those elements can be accepted realistically. This paper argues against preservative realism, in particular through a critical review of Psillos's argument concerning the case of the caloric theory of heat. Contrary to his argument, the historical record of the caloric theory reveals that beliefs about the (...) properties of material caloric, rejected by subsequent theories, were indeed central to the successes of the caloric theory. Therefore caloric remains a favorable case for Laudan. Further, I argue that even confirmed cases of preservation do not warrant an inference to truth. (shrink)

CONTINUOUS MODEL THEORY CHAPTER I TOPOLOGICAL PRELIMINARIES. Notation Throughout the monograph our mathematical notation does not differ drastically from ...

I propose a reformulation of realism, as the pursuit of ontological plausibility in our systems of knowledge. This is dubbed plausibility realism, for convenience of reference. Plausibility realism is non-empiricist, in the sense that it uses ontological plausibility as an independent criterion from empirical adequacy in evaluating systems of knowledge. Ontological plausibility is conceived as a precondition for intelligibility, nor for Truth; therefore, the function of plausibilty realism is to facilitate the kind of understanding that is not reducible to mere (...) description or prediction. Difficulties in making objective judgements of ontological plausibility can be ameliorated if we adhere to the most basic ontological principles. The workings of plausibility realism are illustrated through a detailed discussion of how one ontological principle, which I call the principle of single value, can be employed with great effect. Throughout the paper the discussion draws on concrete examples from the history of science. (shrink)

The primary purpose of this study is to link the effects of consumer personality traits on green buying intention via the mediating variable of consumer ethical beliefs so as to extend the context of green buying intentions with consumer ethics literatures. Based on a survey of 545 Taiwanese respondents, consumer personality traits were found to significantly affect consumer ethical beliefs. The results also indicate that some dimensions of consumer ethical beliefs significantly predict consumer intention to buy green products. Generally speaking, (...) this study enhances our knowledge of consumers’ ethical decision-making in the context of green consumption behaviors. Theoretical and managerial implications, limitations, and future research are also provided. (shrink)

Humans can attribute beliefs to others. However, it is unknown to what extent this ability results from an innate biological endowment or from experience accrued through child development, particularly exposure to language describing others' mental states. We test the viability of the language exposure hypothesis by assessing whether models exposed to large quantities of human language display sensitivity to the implied knowledge states of characters in written passages. In pre‐registered analyses, we present a linguistic version of the False Belief (...) Task to both human participants and a large language model, GPT‐3. Both are sensitive to others' beliefs, but while the language model significantly exceeds chance behavior, it does not perform as well as the humans nor does it explain the full extent of their behavior—despite being exposed to more language than a human would in a lifetime. This suggests that while statistical learning from language exposure may in part explain how humans develop the ability to reason about the mental states of others, other mechanisms are also responsible.

In traditional Chinese literary criticism, textual strategies comparable to intertextuality have governed Chinese critics’ and poets’ reading and writing aboutliterature throughout the dynasties. Drawing on the intertextual theories of Kristeva and Riffaterre, the paper probes into the phenomenon of sign system-mutations in two highly influential ancient texts: the Confucian Classic of Changes of the fifth century B.C.E. and Liu Xie’s The Literary Mind and the Carving of Dragons, an ars poetica in the third century. The transformation of sign (...) systems from nonverbal to verbal, in the case of the Changes, and from literate to literary or “creative” to “theoretical”, in the case of the Dragons, bears witness to the Hjelmslevian reciprocity of object-semiotic and meta-semiotic.

We propose a revision operator on a stratified belief base, i.e., a belief base that stores beliefs in different strata corresponding to the value an agent assigns to these beliefs. Furthermore, the operator will be defined as to perform the revision in such a way that information is never lost upon revision but stored in a stratum or layer containing information perceived as having a lower value. In this manner, if the revision of one layer leads to the (...) rejection of some information to maintain consistency, instead of being withdrawn it will be kept and introduced in a different layer with lower value. Throughout this development we will follow the principle of minimal change, being one of the important principles proposed in belief change theory, particularly emphasized in the AGM model. Regarding the reasoning part from the stratified belief base, the agent will obtain the inferences using an argumentative formalism. Thus, the argumentation framework will decide which information prevails when sentences of different layers are used for entailing conflicting beliefs. We will also illustrate how inferences are changed and how the status of arguments can be modified after a revision process. (shrink)

This article aims to help readers to learn about health care related cultural and religious beliefs and spiritual needs in Chinese communities. The recall diary of a severe acute respiratory syndrome (SARS)-infected intern working in Hoping Hospital in Taiwan during the 2003 SARS epidemic is presented and used to assist in understanding one patient’s spiritual activities when personally confronted with this newly emerging infectious disease. The article also gives an overview of the 2003 SARS epidemic in Taiwan, and discusses people’s (...) general perceptions towards infectious diseases, their coping strategies concerning disease, and their spiritual beliefs, the psychological impact of the 2003 SARS outbreak in Chinese communities, Chinese myths about infectious disease, and the religious activities of a SARS-infected intern in Taiwan. Recommendations are given on how to achieve quality holistic nursing care. (shrink)

The RecA family proteins mediate homologous recombination, a ubiquitous mechanism for repairing DNA double‐strand breaks (DSBs) and stalled replication forks. Members of this family include bacterial RecA, archaeal RadA and Rad51, and eukaryotic Rad51 and Dmc1. These proteins bind to single‐stranded DNA at a DSB site to form a presynaptic nucleoprotein filament, align this presynaptic filament with homologous sequences in another double‐stranded DNA segment, promote DNA strand exchange and then dissociate. It was generally accepted that RecA family proteins function (...) class='Hi'>throughout their catalytic cycles as right‐handed helical filaments with six protomers per helical turn. However, we recently reported that archaeal RadA proteins can also form an extended right‐handed filament with three monomers per helical turn and a left‐handed protein filament with four monomers per helical turn. Subsequent structural and functional analyses suggest that RecA family protein filaments, similar to the F1‐ATPase rotary motor, perform ATP‐dependent clockwise axial rotation during their catalytic cycles. This new hypothesis has opened a new avenue for understanding the molecular mechanism of RecA family proteins in homologous recombination. BioEssays 30:48–56, 2008. © 2007 Wiley Periodicals, Inc.

The problem of Confucius has been the subject of a most heated debate in philosophy circles for several years. Prior to 1962, the major points of debate were: whether the philosophical thought of Confucius is idealistic or materialistic; whether the political thought of Confucius represents [the interests of] the ruined slaveholders or the newly emerged landlord class; and whether the thoughts of Confucius are reactionary or progressive. However, since the spring of 1962 a new trend began to appear. Articles glorifying (...) Confucius began to appear in the press throughout the country. They dealt with Confucian ideas on a profusion of subjects, such as arts, music, military affairs, psychology, and so forth. Some of these articles presented an abstract analysis of Confucian thoughts as transcending all classes and times and made them eternal and "evergreen"; some went as far as to put Marxist ideology under the name of Confucius. Others maintained that we should treasure Confucian thoughts and that any criticism would ruin the legacy. Still others asserted that the policy of treasuring legacy of the Confucian thoughts should be "arrangement, consolidation, and elevation.". (shrink)

Product counterfeiting, a serious problem throughout the world, is particularly challenging for luxury brands, which often have simple designs and a value that depends largely on buyers' perceptions. This study incorporates the concept of customer value into an investigation of the anticounterfeiting strategies. Both hedonic and utilitarian values positively influence customer loyalty toward luxury brands. As a means to strengthen customer values, legal and product strategies positively influence customers' hedonic value, whereas communication and product strategies positively influence their utilitarian (...) value. The managerial implications of these findings and directions for further research are discussed. (shrink)

A focus group study using four groups of food shoppers provides insights into consumers’ knowledge, beliefs, and behaviors regarding organic foods. Two focus groups consisted of shoppers who regularly bought organic foods and two focus groups of shoppers who predominantly purchased conventional foods. Participants in one of the conventional groups were all Caucasian; in the other they were all African-American. While familiarity with organic foods was much lower in the African-American group, its members were more receptive and positive towards organic (...) foods. Likewise, the African-American shoppers were more accepting of price premiums for organics foods. In comparing the two organic shopper groups with the two conventional shopper groups, it was found that the former were generally more knowledgeable about organic foods. They were also more likely to follow a special diet than conventional Caucasian shoppers. However, the behavior of organic shoppers varied widely. The research supports examining social justice and access as motivations for changing policies to support organic agriculture. (shrink)

Consumer ethics is the moral principles and standards that guide consumers to determine the certain consumption behaviors are ethically right or wrong. Whereas cultural and personal dimensions are crucial constructs affecting individual ethical attitudes and behaviors, few studies consider Confucian dynamism and the role of money in consumer ethics. Confucian dynamism, a cultural dimension based on Confucianism, has played a central role in guiding moral obligations and ethics in human relations in several East Asian countries. Thus, this study tested its (...) hypotheses using a sample of 521 respondents obtained via a systematic random sampling technique. The authors find that individuals with a higher tendency to Confucian dynamism are less tolerant of unethical practices. These findings also show that the role of money partially influences consumer ethical beliefs. Finally, we examine the impact of demographic variables and find age and education affect consideration of ethical values. (shrink)

Backpacker travel has become an imperative trend in modern tourism. Previous research, however, has not discussed in-depth the intentions and motivations of accommodation selection, in particular, the religious organization e.g. church, mosque, synagogue, and temple affiliated pilgrim hostel. To fill the gap of previous studies, this study provides a new research direction involving the pilgrim hostel playing an essential role as more than mere pilgrim accommodation; pilgrim hostels in Taiwan have surprisingly included a certain percentage of backpacker tourists. A survey (...) addressed the primary identity and service content perceptions of lodgers. Two historical temple-affiliated pilgrim hostels generated 287 valid responses; 112 backpackers, composing 39 % of the sample units, participated in person. Study findings indicated many significant differences between pilgrims and backpackers regarding self-recognised identity on journeys and perceptions of pilgrim hostel service content (for example, religious identification, reason for lodging, total travel expense, number of nights stayed, customer satisfaction, and service value). Implications of these findings provide suggestions and practical applications for the tourism stakeholder and for future research. (shrink)

Spirituality has been a part of nursing for many centuries and represents an essential value for people, including nurses and patients. Cumulative evidence points to the positive contribution of spiritually on health and wellbeing. However, there is little clarity about what spirituality means. The literature reveals that nurses have ascribed a diversity of interpretations to spirituality. However, no studies have investigated how registered nurses construct their understanding of spirituality using a critical discourse analysis approach. Therefore, the aim of this study (...) was to uncover how registered nurses construct their understanding of spirituality using a critical discourse analysis approach. Twenty registered nurses from a non‐denominational public hospital and a faith‐based private hospital were interviewed about their understanding of spirituality and practice of spiritual care. A critical discourse analysis approach was used in the examination of the interview texts to uncover underlying social and power features. Links were made between the linguistic features the registered nurses used in their interviews and the broader social context of the study. Three discourses emerged from the interview texts. These include constructing spirituality through personal religious beliefs discourse, holistic discourse and empathetic care discourse. The findings of this study have implications for nurse education and policy makers. (shrink)

Abstract Objective Intuitive inquiry meditation is a unique form of Buddhist Zen/Chan practice in which individuals actively and intuitively utilize the cognitive functions to cultivate doubt and explore the concept of the self. This event-related potential (ERP) study aimed to investigate the neural correlates by which long-term practice of intuitive inquiry meditation induces flexibility in self-schema processing, highlighting the role of doubt and belief processes in this exploration. Methods Twenty experienced and eighteen beginner meditators in intuitive inquiry meditation were (...) recruited for this ERP study. The interactions of doubt and belief processes with concepts of the self and Buddha were investigated. A 128-channel electroencephalography (EEG) system was used to collect EEG data. The ERP data were processed and analyzed using EEGLAB. Results The data showed a double dissociation between beginners and experienced meditators (monks) in the concepts of the self and Buddha: intuitive inquiry meditation reduced the brain activity of beginners when viewing Buddha image but not when viewing a picture of themselves. However, in experienced meditators, intuitive inquiry meditation reduced brain activity when they viewed images of themselves but not when they viewed Buddha image. Further event-related spectral perturbation (ERSP) analysis revealed that experienced meditators had a greater theta spectral power and higher intertrial coherence (ITC), indicating that they could more flexibly modulate ongoing cognitive processes than beginner meditators. Conclusion Intuitive inquiry meditation could help beginner meditators detach from the concept of Buddha but not from that of the self. However, in experienced meditators, the opposite was true. ERSP analysis showed that only experienced meditators exhibited significant alterations in brain activity dynamics during intuitive inquiry meditation, which might enable these practitioners to become spontaneously detached from the concept of the self. These findings revealed the neural mechanism by which long-term practice of intuitive inquiry meditation can influence the doubting process and its effect on self-schema processing. (shrink)

While the traditional economic wisdom believes that an individual will become better off by being given a larger opportunity set to choose from, in this paper we question this belief and build a formal theoretical model that introduces decision costs into the rational decision process. We show, under some reasonable conditions, that a larger feasible set may actually lower an individual’s level of satisfaction. This provides a solid economic underpinning for the Simon prediction.

continent. 1.4 (2011): 279—285. Concerning its Transitive Nature, the Conversion of Native Americans of Spanish Colonial California, Indoctrinated Catholicism, & the Creation There’s no direct archaeological evidence that Jesus ever existed. 1 I memorized the Act of Contrition. I don’t remember it now, except the beginning: Forgive me Father for I have sinned . . . This was in preparation for the Sacrament of Holy Reconciliation, where in a confessional I confessed my sins to Father Scott, who looked like Jesus, (...) at least in Western cultural representations of Jesus since the middle ages, and if Jesus put on a few pounds. Father Scott was long-haired, redheaded, bearded, chubby, and tall. When he left church with the procession of altar servers and Eucharistic ministers, yelling, “Sing a Good Song Unto the Lord,” he smiled, hands folded, and he gazed over his parishioners, and bounced along. For four months every year he lived among the Crow Nation in Montana, where towards the end of his tenure at Our Lady of Refuge, they adopted him as an honorary member of their tribe. * This is the prayer we chanted, holding hands, every night before dinner: Bless us oh Lord, for these our gifts, which we are about to receive, our bounty through Christ, our Lord, Amen. Then we all said, God bless the cook! When we were with my grandparents, Grandpa said, God bless Chicky, and Holly, and Harvey, and Boots—all the dead dogs. * My sister tells me that she sits next to a handsome man on a flight across the country. After chitchat, she withdraws her book. She’s reading Kevin Sampsell’s A Common Pornography . After a few moments, the handsome man also reads from his book—his leather-bound Bible. Sister thinks, Oh, Jesus—too bad. She falls asleep. Later, settled in Nashville, she opens her volume and out falls a Jesus-covered card that reads, You can still find God and Salvation! Because that handsome God-fearing young man saw that word— pornography . * I suppose Father Jim’s dark hair, beard, and glasses made me think doctoral-ly of him. He called while I was in the midst of a breakup, after I’d twice attempted suicide, and my mother was desperate for help. She somehow found and phoned him. And Jim, now years out of Our Lady of Refuge’s parish, twenty years since my baptism, years even since he’d left the priesthood and the Catholic faith, still made the effort to bring me back into the fold. He said, “Have you seen a priest?” I did not respond, as I was more shocked to hear his voice than anything, so I said, “How are you, Father Jim? Sorry, I guess I shouldn’t call you ‘Father.’” And I said, “Why did you leave the priesthood? Do you have a girlfriend?” He said that I should call him just “Jim.” He said, “Do you need someone to talk to?” I said, “Not really.” He said, “Call your mother; she’s worried about you.” That was the last time I talked to Father Jim. * Mother let me know just how disappointed Jesus was. I cried and cried, and said I was sorry. Into my hands she placed my missal, ordered forty Rosaries. She said next Saturday I would go to confession. I hated confession. Who wouldn’t? * I realize, of course, that this page is a kind of confessional. * The Kumeyaay, Ipai, Tipai, Chumash, Esselen, Rumsen—all Native Americans of Alta California—shared similarities in their religions. Southern Californian tribes made use of Datura, or jimpson weed, a hallucinogen, for religious rituals. In the creation, God made brother sky and sister earth. Brother and sister mated, and sister gave birth to all things on Earth, including people, but it was difficult to distinguish people from all other aspects of Earth because everything was alive: granite and obsidian, the Pacific and its waves, the San Diego and Los Angeles Rivers. Wiyot—a hero—was very powerful, born from lightning, the son of the Creator and a virgin. When Wiyot thought that human women’s legs were more beautiful than Frog’s, Frog became jealous and poisoned Wiyot. The dying Wiyot went to all the people’s villages, and he distributed his power among them. He said, “When I die, I should be cremated.” The people built the fire and funeral pyre. When the fire was ready, and the people about to place Wiyot’s body upon it, Coyote came and snatched away Wiyot’s heart. * My friend Nick told me once how he ate some jimpson weed and that he hallucinated for three days. His family took a road trip and, while driving over the Sierra Nevada mountains, he kept seeing dinosaurs roaming the open meadows and charging down snowy slopes. So it’s no wonder that Native Americans who ingested this plant would have developed religion. * Walking Castroville’s streets after school I got into fights but mostly watched other boys scrabbling on the asphalt. I went to Burger King for Whoppers. Me and my friends cussed. Antonio admonished me when I said, “damn,” while strutting a sidewalk alongside the church. He said, “Jaime”—pronounced Hi-May, which was what all the Mexicans called me—“you’re crazy, eh. Don’t cuss at the church.” He meant while at church, as in, within its vicinity. I said, “We’re not in church.” Once we’d crossed the street, Tony said, “Damn dude, you’re fuckin crazy!” * Blessed Father Fray Junípero Serra raised the Eucharistic goblet to his lips, and candlelight danced on the blood’s tiny waves. Incense clouded the church so completely that some of the Pame natives grew nauseous. So, too, felt Blessed Father Fray Junípero Serra later that night, as he bent over a ceramic bowl and vomited blood, not only the Lord’s, but his own, for poison had laced the sacred vessel into which he poured the sacrament. The physician tending to the sick prelate urged him to take the remedy he’d prepared. But Blessed Father Fray Junípero Serra refused, said that he would pray, for he had never taken any medicine in his life, and he never would. * The Chumash of El Valle de Los Osos called themselves the Stishni, separating themselves from Chumash of other regions, those varying tribes of the central California coast that spoke mutually unintelligible dialects of their Hokan language. This made learning their languages impossible for the Spanish friars, to say nothing of translating the Doctrina. Thus the priests baptized few natives, despite the help that the tribes offered the fledgling settlements in the form of meat and acorn meal, which the Spaniards found repugnant. Some from these cultures, feeling threatened by the newcomers, shot flaming arrows into the thatched roofs of the mission structures. And why wouldn’t they feel threatened when priests chastised them for performing, for example, their Coyote Dance, wherein a man donning a coyote-skin-and-skull costume dances while a singer sings his tale, which laments the human feces strewn imaginatively about the Earth? Coyote, meantime, tries to get an onlooker to lick his genitals, and finally engages in public sexual intercourse with a female tribe member or two, then ends the dance by defecating. Though the Franciscans called such forbidden acts devilry , the Chumash maintained their Datura cult religion, along with the enforced Christianity. For the Chumash, the Earth was made of two enormous snakes that caused earthquakes when they slithered past one another—a vast reptilian tectonics. In the 20th century, long after Blessed Father Fray Junípero Serra and his cohorts had died, when asked by an anthropologist about religious contradictions, conflating the Datura and Christian cults, a Chumash man replied, incredulous: “But these are two different religions.” * When Portolá ordered that if by March 19th, the feast day of St. Joseph, the San Antonio had not arrived in San Diego Bay to relieve them, the Sacred Expedition to Nueva California would be abandoned, Blessed Father Fray Junípero Serra prayed a novena for San José’s intercession. And lo, a lookout sighted the San Antonio ’s sails—what seemed to the priest a miracle—that very Saint’s feast day. Europeans would stay in California, and Blessed Father Fray Junípero Serra would continue to reap a great harvest of souls for the Lord. By the end of mission secularization in 1836—sixty-six years after the San Antonio rescued the Spaniards—Native American populations in California had declined by seventy-three percent. * When Peter the Aleut would not renounce his Eastern Orthodox faith the padre of San Francisco had a toe severed from each foot with each refusal, totaling ten. The native Ohlones employed in this gruesome task—their obsidian chiseled knives tearing through skin and grinding bone—continued as per their orders, and cut off also each of Peter’s fingers (equals a total of twenty refusals). They quartered the martyr, spilled his bowels, as if from bear attack, attack by a bear in the shape of a Catholic. * Blessed Father Fray Junípero Serra absolutely believed that the slow rate of conversion for the native people was due to the influence of the Devil, who had been outraged by the coming of the Catholics to California, this region that he had long held in his dominion. * In his reception speech for the Nobel Prize for Literature, John Steinbeck said, “Man himself has become our greatest hazard and our only hope. So that today, St. John the Apostle may well be paraphrased: In the end is the Word, and the Word is Man—and the Word is with Men.” * In 1602, when Sebastián Vizcaíno and his friars sang mass on Catalina Island, as many as a hundred Pimungans witnessed the rite, asking by signs what it was about. According to Vizcaíno’s records, the Californians marveled not a little at the idea of Heaven and at the image of Jesus crucified. * Vizcaíno was brought to a prairie on Santa Catalina Island where the Pimungans worshipped their sun god. Upon the prairie they had placed an icon, a headless figure with horns protruding from the body, a figure that Vizcaíno predictably described as a demon. The Pimungans urged Vizcaíno not to approach the image of their deity, but he ignored them. He placed his crucifix against the wooden figurine and prayed the Our Father. Vizcaíno told the natives that his prayer was from Heaven, and that their god was the Devil. Vizcaíno held out his crucifix, encouraging the Pimungans to touch it and receive Jesus. He pointed at the sky and indicated Heaven. The Pimungans worshipped a sun deity, so they were impressed with this white man and his description of his god, for their gods seemed to be one and the same. It’s no wonder then that Vizcaíno’s diary reports the natives being pleased with this exchange. “Surely,” the diary says, “they will be converted to our Holy Faith.” * The Miwok women wailed and scratched at their faces when their men consorted with Sir Francis Drake and the other Englishmen who had landed on California’s coast in the summer of 1579. “The blood streaming downe along their brests, besides despoiling the upper parts of their bodies of those single coverings . . .they would with furie cast themselves upon the ground . . . on hard stones, knobby hillocks, stocks of wood, and pricking bushes.” Drake and his men fell themselves to their knees in prayer, their eyes Heavenward, so that the natives might see they prayed to God and they too might worship God then their eyes that had been so blinded by the deceiver might be opened. * Father Fray Antonio de la Ascención—Carmelite friar in Vizcaíno’s party—writes that the Indians of California can “easily and with very little labor be taught our Holy Catholic faith, and that they would receive it well and lovingly.” He calls for two hundred older and honorable soldiers to ensure brotherhood during the conquest, so that peace and love—the best tools to pacify pagans—should reign. The religious, the friar says, should likewise be wise and loving to easily quell animosities between Spaniards and the heathen, and therefore avoid war. The Spaniards should bring with them trinkets—beads, mirrors, knives—to distribute amongst the gentiles, so that they might come to love the Christians, and see “that they are coming to their lands to give them that of which they bring, and not to take away the Indians’ possessions, and may understand that they are seeking the good of their souls.” No women are to accompany the conquest, says Father Fray Antonio, “to avoid offenses to God.” * In 1955 Wallace Stevens admitted himself to St. Francis Hospital in Hartford, Connecticut. There, it’s rumored he converted to Catholicism before dying of stomach cancer, exclaiming to his priest after the baptism, “Now I am in the fold.” Stevens’s late-career poems seem less cynical, more in awe of being and death (read “Metaphor as Degeneration” from The Auroras of Autumn ). He could have chosen from at least three secular hospitals in Hartford at the time. * I was reading Stevens’s Collected Poems when I joined eHarmony and listed that as my “currently reading” book among the “more than twelve” books a year that I would read. I fell in love with my wife when she said, “Are you sending your work out to literary journals?” Prior to this, the first girl I talked to on the phone, when I explained my doctoral exams, said, “So, you’re like, reading Stephen King and stuff?” When I said not exactly she responded defensively: “He must be doing something right, since he makes all that money.” * Mom walked me, my brother, and sister, through the Stations of the Cross. We did this on Ash Wednesdays, or whenever she thought we needed extra God after church. It might’ve happened before church, though that’s unlikely because we were always late. Anyway, it’s easiest to walk the Stations of the Cross when there’s no one else around. To walk the actual Stations means one goes to Jerusalem and walks the Via Dolorosa to the Church of the Holy Sepulchre. So the Stations elsewhere—usually paintings, or low-relief sculptures upon church walls—serve as a kind of virtual Dolorosa. Mom held our hands and started from the rear of Our Lady of Refuge: the First Station. Mom said we should say a prayer at each Station and to think of all the pain Jesus went through so that we could go to Heaven. It was hard to keep thinking about that one thing for so long. My mind went to that Saturday’s little league game, to the donut and chocolate milk (our after-church reward from Castroville Bakery), and as I grew older I thought about girls. When you’re thirteen you can’t not think about the girl’s butt in the pew in front of yours as she kneels and stands to pray throughout mass. * It grew increasingly juvenile to lie awake at night daring myself to utter a simple sentence. Even if I said I didn’t believe in God, wouldn’t He know the truth? He was omniscient, like a narrator. Even the idea of Him as a him ceased making sense. Not only did this come with a budding realization of my paternalistic culture, but due to the simple question of why? If God was everything, everywhere, all knowing, then why would he be a man? There’s that question: If God is a man then God must have a penis, and if so, what for? * The Catholic Church incorporates some modern scientific research into its dogma concerning the formation of the Universe, Solar System, and Earth, as well as evolution. According to Catholic doctrine, in approximately the fifth millennia BCE, humans began to worship the one true God. Those humans were Adam and Eve, though the Church says humans had been around for thousands of years prior to Adam and Eve. The Church claims to be infallible. Every time the Church changes its doctrine it remains infallible. * One Catholic writer, Tom Meagher, writes that “Modernism[—]the idea that we come to our beliefs individually through emotional or personal experiences[—]has crept into our Catholic schools.” * Catholics believe that evil spirits, given power through Original Sin, can imbue ordinary inanimate objects of everyday use. Thus, such objects should be blessed in order to induce in them the desire to serve the good. Such objects are not limited to, but include, “new ships and boats, railways and trains, bridges, fountains, wells, cornmills, limekilns, smelting furnaces, telegrams, steam engines, and machines for providing electricity.” * In The Sound of Music Julie Andrews and Christopher Plummer sing together: “Nothing comes from nothing, nothing ever could...” * To explain competing theories on the very early universe, and pre-verse would be another book. What was the inflaton? Did (mem)branes collide, initiating the Big Bang, as opposed to Lemaître’s primordial atom, a singularity? Without a unified theory there’s gravity hanging out there, fucking everything up. We cannot make sense of the mechanics of the Planck Epoch—0-10-34 seconds into the Universe’s creation—named for Max Planck, who stumbled into the discovery of quantum mechanics in the early twentieth century. * My students often ask if I believe in God, since I espouse evolution, the Big Bang, Science, reject a strictly biblical or creationist theory of the Universe. I tell them that yes, I believe in God, though not the God that they imagine one must believe in. * When questioned regarding the rumor that, before his death, founder of quantum mechanics Max Planck had converted to Catholicism, he replied that he did not believe “in a personal God, let alone a Christian God.” * Physicist and Catholic priest George Lemaître, who formulated the theory and wrote the 1946 book The Primeval Atom Hypothesis , was made a household name by then-detractor Fred Hoyle, who pejoratively referred to the idea as a “Big Bang.” * Suicide is a mortal sin. To end one’s own life one must have despair, which is to lose hope, which is to lose faith, and to disbelieve in God. * Archaeology has uncovered graffiti in all of California’s missions—Indian pictographs inscribed into the adobe, covered with layers of whitewash. Native deities and depictions of cultural practices show that tribespeople never fully gave up their native traditions even after baptism and coming to the missions. There was something inside Native Californians that would never die. (shrink)

Among the beliefs Wittgenstein holds that cannot be taken to be true or false, but rather appear to him as certain, are "all human beings have parents" (On Certainty §240): "I believe that I have forebears and that every human being has them" (OC §240) and "I have a father and a mother" (OC §282). I ask what moral questions are entailed in thinking of the changes that our current Western conceptual landscape has undergone in relation to parenthood and (...) family life in the light of the growing rights and recognition of sexual and gendered minorities. What is changing when we start to think of sentences such as "Everyone has a father and a mother" as not expressing an indubitable truth, a fundamental fact of our existence, but as constituting an oppressive social norm? What has already changed in our ways of conceiving of ourselves when we stop regarding such ways of expressing ourselves as a necessary aspect of our natural history but start thinking of them as one possibility among others in finding good and meaningful forms of life?

In this paper I shall attempt to argue for the simple view of personal identity. I shall first argue that we often do have warrant for our beliefs that we exist as continuing subjects of experience, and that these beliefs are justified independently of any reductionist analysis of what it means to be a person. This has two important implications that are relevant to the ongoing debate concerning the number of persons that are in existence throughout any duration in (...) time: (1) the lack of logically or metaphysically necessary and sufficient conditions for distinguishing one person from another should imply neither that there is only one person nor that personhood is not individuative; and (2) the lack of such universally applicable identity criteria should not imply that the term ‘person’ is a folk term with no real application. In other words, lack of reductionist analysis does not entail lack of existence. (shrink)

A sentence A is epistemically less entrenched in a belief state K than a sentence B if and only if a person in belief state K who is forced to give up either A or B will give up A and hold on to B. This is the fundamental idea of epistemic entrenchment as introduced by Gärdenfors (1988) and elaborated by Gärdenfors and Makinson (1988). Another distinguishing feature of relations of epistemic entrenchment is that they permit particularly simple (...) and elegant construction recipes for minimal changes of belief states. These relations, however, are required to satisfy rather demanding conditions. In the present paper we liberalize the concept of epistemic entrenchment by removing connectivity, minimality and maximality conditions. Correspondingly, we achieve a liberalization of the concept of rational belief change that does no longer presuppose the postulates of success and rational monotony. We show that the central results of Gärdenfors and Makinson are preserved in our more flexible setting. Moreover, the generalized concept of epistemic entrenchment turns out to be applicable also to relational and iterated belief changes. (shrink)

This book explains how the logic of theory change employs formal models in the investigation of changes in belief states and databases. The topics covered include equivalent characterizations of AGM operations, extended representations of the belief states, change operators not included in the original framework, iterated change, applications of the model, its connections with other formal frameworks, and criticism of the model.

In this paper it is argued that, in order to solve the problem of iterated belief change, both the belief state and its input should be represented as epistemic entrenchment (EE) relations. A belief revision operation is constructed that updates a given EE relation to a new one in light of an evidential EE relation. It is shown that the operation in question satisfies generalized versions of the Gärdenfors revision postulates. The account offered is motivated by Spohn's (...) ordinal conditionalization functions, and can be seen as the Jeffrization of a proposal considered by Rott. (shrink)

The axiom of recovery, while capturing a central intuition regarding belief change, has been the source of much controversy. We argue briefly against putative counterexamples to the axiom—while agreeing that some of their insight deserves to be preserved—and present additional recovery-like axioms in a framework that uses epistemic states, which encode preferences, as the object of revisions. This makes iterated revision possible and renders explicit the connection between iterated belief change and the axiom of recovery. We provide a (...) representation theorem that connects the semantic conditions we impose on iterated revision and our additional syntactical properties. We show interesting similarities between our framework and that of Darwiche–Pearl (Artificial Intelligence 89:1–29 1997). In particular, we show that intuitions underlying the controversial (C2) postulate are captured by the recovery axiom and our recovery-like postulates (the latter can be seen as weakenings of (C2)). We present postulates for contraction, in the same spirit as the Darwiche–Pearl postulates for revision, and provide a theorem that connects our syntactic postulates with a set of semantic conditions. Lastly, we show a connection between the contraction postulates and a generalisation of the recovery axiom. (shrink)

This paper is concerned with the construction of a base contraction (revision) operation such that the theory contraction (revision) operation generated by it will be fully AGM-rational. It is shown that the theory contraction operation generated by Fuhrmann's minimal base contraction operation, even under quite strong restrictions, fails to satisfy the "supplementary postulates" of belief contraction. Finally Fuhrmann's construction is appropriately modified so as to yield the desired properties. The new construction may be described as involving a modification of (...) safe (base) contraction so as to make it maxichoice. (shrink)

This paper uses Popper's treatment of probability and an epistemic constraint on probability assignments to conditionals to extend the Bayesian representation of rational belief so that revision of previously accepted evidence is allowed for. Results of this extension include an epistemic semantics for Lewis' theory of counterfactual conditionals and a representation for one kind of conceptual change.

We discuss various possibilities for developing a dynamic doxastic logic (DDL) for introspective agents: agents who have the ability to form higher-order beliefs. Such agents can reflect upon and change their minds about their own beliefs. The project of constructing such a logic, full DDL or DDL unlimited, is ridden with difficulties due to the fact that the agent's own doxastic state now becomes a part of the reality he is trying to explore. When an introspective agent learns more about (...) the world (and himself), the reality he holds beliefs about undergoes a change in its doxastic part, which means that his introspective beliefs have to be adjusted accordingly.

We present the logic $${\mathsf {LCB}}$$ LCB which is expressed in a propositional language constantly enriched by new atomic expressions. Our formal framework is the propositional doxastic logic $${\mathsf {KD45}}$$ KD 45 with the belief operator $${\mathcal {B}}$$ B, extended by the $${\mathcal {C}}$$ C operator, to be read it changes that.... We describe the changing beliefs of an agent who uses progressively expanding language. The approach presented here allows us to weaken pragmatic objections to the so-called principle (...) of negative retrospection accepted in $${\mathsf {KD45}}$$ KD 45 and the problem of logical omniscience. In what follows, we present the expanding propositional language used in our formalism, interpreted using an epistemic version of Kripke semantics. Next, we give a syntactic characterization of logic $${\mathsf {LCB}}$$ LCB and prove the soundness and completeness of $${\mathsf {LCB}}$$ LCB in respect to our semantics. Finally, we compare the idea of expanding language with the notion of agent awareness and we relate our formalism to two epistemic temporal logics. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Veritas Filia Temporis: Experience and Belief in Early Modern Culture *Brendan DooleyFew observers in the seventeenth century had any illusions about the reliability of political information imparted by the sources newly minted or voluminously increased during the course of the century. The newsletters appeared to be concocted from malicious gossip. 1The newspapers seemed to be published at the bidding of powerful political interests with little inclination to tell (...) the truth, 2and histories of recent events seemed to be based on faulty sources even when the writers endeavored to procure faithful accounts. “Truth is by nature elusive and slippery,” history theorist Agostino Mascardi admitted. All he could recommend as a defense for the inaccurate historian was the injunction against throwing the first stone: “Omnis homo mendax,” said David the holy king; and those who are such harsh critics of historians’ involuntary lies may well be astute trammelers of perfidy and deceit in their own lives.” 3He had no answer about historians who deliberately distorted the truth. In fact just when readers might have desired it most, from the earliest episodes of the Thirty-Years War to the last episodes of the Turkish Wars at the end of the century, the possibility of [End Page 487]gaining a realistic picture of the contemporary world seemed to be getting more and more remote.The argument of this article centers around a discussion of the cultural consequences of this late seventeenth-century trend. To some of the readers, writers, thinkers, and theorists in this period, the unreliability of information about their own time or about the past, however compounded by contemporary political and social circumstances, was nothing but a minor nuisance. To others it was a hint about the bad faith of the governments who influenced writers. To still others, this same unreliability raised deeply troubling questions about human nature and existence. It provided social and political reasons for historical skepticism, quite apart from one’s familiarity with Sextus Empiricus or the elite intellectual trends of the time. It placed everyday social and political reality in a new light, thus adding a more mundane element to the uneasy feeling produced by the new science and cosmology—the feeling, that is, of being borne along in uncontrollable currents whose exact nature the best minds nonetheless seemed incapable of understanding. It added to the disquiet produced by confessional disputes, suggesting that truth might be beyond human capacity to grasp. 4Not only in Italy but throughout Europe in the late seventeenth century this discussion will show, existing methods of ascertaining facts in political and military affairs both in the present and in past times came under a new sort of scrutiny as part of what some scholarship has regarded as no less than a wide-ranging “crisis of consciousness” at the threshold of the Enlightenment. 5The conclusion opens briefly onto the sequel of these episodes. The crisis was resolved at least in part by a corresponding movement for methodological change as well as by a reform of ideas about the proper place for intellectual improvisation in the formation of narrative in order to make historical writing persuasive as well as civically useful again. If the product of error and fraud was skepticism, the product of skepticism was modern historiography. 6 [End Page 488]History and ExperienceObviously, the elusiveness of political truth that helped touch off the late seventeenth-century crisis was no novelty of the age. Deliberate misinformation was a fully-recognized political strategy at least by the time that Machiavelli made it an explicit part of prudence by recommending the cultivation of good appearances and expressing his admiration for Pope Alexander VI and Ferdinand I of Spain as being the best liars of their time. 7In the late sixteenth century theorists all over Europe sought to join Machiavelli’s insights about the inner workings of state power to those of Tacitus in the light of conventional morality. 8In Italy it was the Piedmontese writer Giovanni Botero who, exploring these Tacitist perspectives in his Reason of State, expressed the fewest reservations about insisting on the propriety of a policy of state secrecy and misinformation. 9Florentine political theorist...

We give a model for iterated belief change in multi-agent systems. The formal tool we use for this is a combination of modal and dynamic logic. Two core notions in our model are the expansion of the knowledge and beliefs of an agent, and the processing of new information. An expansion is defined as the change in the knowledge and beliefs of an agent when it decides to believe an incoming formula while holding on to its current propositional beliefs. (...) To prevent our agents from forming inconsistent beliefs they do not expand with every piece of information they receive. Instead, our agents remember their original beliefs and every piece of information they receive. After every receipt of information they decide which subset of the received information should be incorporated into their original beliefs. This procedure is called the processing of new information. We show that our model of belief update behaves in an intuitive way and that it is not sensitive to criticism on comparable models. (shrink)

We propose a translation into Modal Logic of the ideas that formalise belief change in the Situation Calculus. This translation is extended to the case of revision. In the conclusion is presented a set of open issues.

Two systems of belief change based on paraconsistent logics are introduced in this article by means of AGM-like postulates. The first one, AGMp, is defined over any paraconsistent logic which extends classical logic such that the law of excluded middle holds w.r.t. the paraconsistent negation. The second one, AGMo , is specifically designed for paraconsistent logics known as Logics of Formal Inconsistency (LFIs), which have a formal consistency operator that allows to recover all the classical inferences. Besides the three (...) usual operations over belief sets, namely expansion, contraction and revision (which is obtained from contraction by the Levi identity), the underlying paraconsistent logic allows us to define additional operations involving (non-explosive) contradictions. Thus, it is defined external revision (which is obtained from contraction by the reverse Levi identity), consolidation and semi-revision, all of them over belief sets. It is worth noting that the latter operations, introduced by S. Hansson, involve the temporary acceptance of contradictory beliefs, and so they were originally defined only for belief bases. Unlike to previous proposals in the literature, only defined for specific paraconsistent logics, the present approach can be applied to a general class of paraconsistent logics which are supraclassical, thus preserving the spirit of AGM. Moreover, representation theorems w.r.t. constructions based on selection functions are obtained for all the operations. (shrink)

In this paper, it is argued that both the belief state and its input should be represented as epistemic entrenchment (EE) relations. A belief revision operation is constructed that updates a given EE relation to a new one in light of an evidential EE relation, and an axiomatic characterization of this operation is given. Unlike most belief revision operations, the one developed here can handle both multiple belief revision and iterated belief revision.

One of the standard principles of rationality guiding traditional accounts of belief change is the principle of minimal change: a reasoner's belief corpus should be modified in a minimal fashion when assimilating new information. This rationality principle has stood belief change in good stead. However, it does not deal properly with all belief change scenarios. We introduce a novel account of belief change motivated by one of Grice's maxims of conversational implicature: the reasoner's belief (...) corpus is modified in a minimal fashion to assimilate exactly the new information. In this form of belief change, when the reasoner revises by new information p ∨ q their belief corpus is modified so that p∨q is believed but stronger propositions like p∧q are not, no matter what beliefs are in the reasoner's initial corpus. We term this conservative belief change since the revised belief corpus is a conservative extension of the original belief corpus given the new information. (shrink)

We must change our beliefs, and change them in particular ways, in response to new information. But not all changes are created equal: some are rational changes, some not. The Problem of Epistemic Change is the problem of specifying the rational constraints on how the epistemic state of an agent ought to change in the face of new information. This dissertation is about the philosophical and logical investigation of rational belief change. I start by arguing that the (...) familiar foundations---coherence distinction from static epistemology does not adequately carve up the logical space of theories of epistemic change. It is better to think of theories as being loosely ordered along a continuum from more to less foundational. The ordering, however, is "clumpy" in the sense that there are large regions in the ordering which remain unexplored. I then present and develop GDEC which is a new foundations model of belief revision that fills a gap in this ordering of theories of epistemic change. The key insight in GDEC is that belief that...is ambiguous between the attitudes of accept that...and expect that... GDEC respects the difference and how it matters for epistemic change. I show that GDEC is a genuine competitor to the AGM theory of belief revision in the sense that the two approaches are incompatible. The remainder of the dissertation is devoted to exploring the logical dynamics of GDEC and the models I develop here which extend it by applying them to a series of richer epistemic environments. I show how puzzles and paradoxes which confound other theories of belief revision are solved in a unified way by GDEC and its extensions. In particular, I give solutions to Moore's Paradox, Fuhrmann's Impossibility Theorem, the Reduction Problem of Epistemic Conditionals, and the Gardenfors Impossibility Theorem. (shrink)

This paper analyzes the notion of a minimal belief change that incorporates new information. I apply the fundamental decision-theoretic principle of Pareto-optimality to derive a notion of minimal belief change, for two different representations of belief: First, for beliefs represented by a theory – a deductively closed set of sentences or propositions – and second for beliefs represented by an axiomatic base for a theory. Three postulates exactly characterize Pareto-minimal revisions of theories, yielding a weaker set of (...) constraints than the standard AGM postulates. The Levi identity characterizes Pareto-minimal revisions of belief bases: a change of belief base is Pareto-minimal if and only if the change satisfies the Levi identity (for “maxichoice” contraction operators). Thus for belief bases, Pareto-minimality imposes constraints that the AGM postulates do not. The Ramsey test is a well-known way of establishing connections between belief revision postulates and axioms for conditionals (“if p, then q”). Pareto-minimal theory change corresponds exactly to three characteristic axioms of counterfactual systems: a theory revision operator that satisfies the Ramsey test validates these axioms if and only if the revision operator is Pareto-minimal.

Traditional accounts of belief change have been criticized for placing undue emphasis on the new belief provided as input. A recent proposal to address such issues is a framework for non-prioritized belief change based on default theories (Ghose and Goebel, 1998). A novel feature of this approach is the introduction of disbeliefs alongside beliefs which allows for a view of belief contraction as independently useful, instead of just being seen as an intermediate step in the process (...) of belief revision. This approach is, however, restrictive in assuming a linear ordering of reliability on the received inputs. In this paper, we replace the linear ordering with a preference ranking on inputs from which a total preorder on inputs can be induced. This extension brings along with it the problem of dealing with inputs of equal rank. We provide a semantic solution to this problem which contains, as a special case, AGM belief change on closed theories. (shrink)

All formal models of belief change involve choices between different ways to accommodate new information. However, the models differ in their loci of choice, i.e. in what formal entities the choice mechanism is applied to. Four models of belief change with different loci of choice are investigated in terms of how they satisfy a set of important properties of belief contraction and revision. It is concluded that the locus of epistemic choice has a large impact on the (...) properties of the resulting belief change operation. (shrink)

In this paper we present a brief overview of logic-based belief change, a research area concerned with the question of how a rational agent ought to change its mind in the face of new, possibly conflicting, information. Our intention is to provide the reader with a basic introduction to the work done in this area over the past 30 years. In doing so we hope to sketch the main historical results, provide appropriate pointers to further references, and discuss some (...) current developments. We trust that this will spur on the interested reader to learn more about the topic, and perhaps to join us in the further development of this exciting field of research. (shrink)
