Purpose: A retraction is the removal of a published article from the scientific record. It is an admission of failure. Yet, every retraction, regardless of its cause(s), is instructive. Using the oxymoron/concept of celebrating failure, this study investigates retractions in the Journal of Consumer Research (JCR). -/- Method: The content of each JCR retraction notice was examined to determine the initiator(s) of the retraction, retractors, reason(s) for retraction, and time-to-retraction. -/- Findings: According to the findings, JCR issued ten retraction notices (...) between June 2012 and October 2020. The ten retraction notices generated together, and up to April 11, 2022, some 18,378 pageviews, 3,944 PDF. (shrink)

Cette étude a pour objet de démontrer l’évolution de la théorie de l’acte abstrait, son déclin durant les époques antérieures et sa renaissance à l’époque moderne. De ce fait nous étudions d’une part les éléments d’abstraction et leur relation avec le principe dit de « formalité » appliqué auparavant en droit romain, et d’un autre part nous nous pencherons sur les raisons du déclin de la notion de l’acte abstrait, et sa réapparition de nouveau à l’époque moderne, tout en essayant (...) d’établir un décryptage des résultats de cette théorie et d’insister sur les valeurs de l’abstraction dans l’acte juridique notamment s’il porte sur l’aspect économique dans les sociétés en développement, dont les pays arabes.

Sometimes, political bald-faced lies pass for truth. That is, certain groups of people behave according to them – behave as if the political bald-faced lies were true. How can this phenomenon be explained? I argue that to explain it we need to take political bald-faced lies to be performative utterances whose goal is to bring about a worldly state of affairs just in virtue of making the utterance. When the former US-President tweeted ‘we won the election’, people stormed Capitol Hill (...) to protest election fraud and some were killed. In this way, the bald-faced lie was successful in passing for truth. My performative view of political bald-faced lies is to be preferred over various other views such as the contempt for truth view (Lynch 2021), the deception view (Lackey 2013), and the value-signaling view (Stanley 2012). These alternative views fail to adequately account for how political bald-faced lies pass for truth. (shrink)

Donald Trump and Boris Johnson are notoriously uninterested in truthtelling. They also often appear uninterested even in constructing plausible falsehoods. What stands out above all is the brazenness and frequency with which they repeat known falsehoods. In spite of this, they are not always greeted with incredulity. Indeed, Republicans continue to express trust in Donald Trump in remarkable numbers. The only way to properly make sense of what Trump and Johnson are doing, we argue, is to give a greater role (...) to audience relativity - and in some cases, audience participation - in notions like bullshitting and bald-faced lying. In this paper, we develop a new understanding of bullshitting, one that includes bald-faced lying, and recognizes that different communicative acts may be directed at different audiences with a single utterance. In addition, we argue for recognition of the category of bald-faced bullshitting, a particular speciality of both Trump and Johnson, and one especially useful to authoritarian leaders. (shrink)

In Lying and Insincerity, Andreas Stokke argues that bald-faced lies are genuine lies, and that lies are always assertions. Since bald-faced lies seem not to be aimed at convincing addressees of their contents, Stokke concludes that assertions needn’t have this aim. This conflicts with a traditional version of intentionalism, originally due to Grice, on which asserting something is a matter of communicatively intending for one’s addressee to believe it. I argue that Stokke’s own account of bald-faced lies faces serious problems (...) and give several responses on behalf of intentionalism. Some bald-faced lies are best understood as irrational attempts to deceive. Others are best understood as indirect speech acts of various kinds. Still, others are best understood as conventional speech acts, which differ from communicative acts like assertion in the ways that they must be embedded in social institutions or practices. An overarching theme of this essay is that we should not make theoretical decisions about how to classify speech acts by consulting ordinary usage. (shrink)

All of the South Plains archetypes listed above are all drawn from real flesh-and- bones type of individuals. Moreover, all were men of action. The archetypes of the Turkish Oral Narrative generally have a longer historical background, and, as their tales attest, are compelled to take action against real or perceived injustices. In most cases, the Turkish archetypes primarily function as teachers or teaching tools, continually adapting to changing conditions and periods.

In this chapter, I try to answer the above question, and another question that it presupposes: can philosophy of language help us navigate the political news cycle? A reader can be sceptical of a positive answer to the latter question; after all, citizens, political theorists, and journalists seem to be capable of following current politics and its coverage in the news, and there is no reason to think that philosophy of language in particular should be capable of helping people make (...) sense and respond to the news. I will illustrate the application of philosophy of language to three contrasting strategies of political propaganda: dogwhistles, meaning perversions, and bald-faced lies. I hope that these help us see that philosophy of language can be a good tool in diagnosing demagoguery, and in resisting it. (shrink)

There is a familiar debate between Russell and Strawson concerning bivalence and ‘the present King of France’. According to the Strawsonian view, ‘The present King of France is bald’ is neither true nor false, whereas, on the Russellian view, that proposition is simply false. In this paper, I develop what I take to be a crucial connection between this debate and a different domain where bivalence has been at stake: future contingents. On the familiar ‘Aristotelian’ view, future contingent propositions are (...) neither true nor false. However, I argue that, just as there is a Russellian alternative to the Strawsonian view concerning ‘the present King of France’, according to which the relevant class of propositions all turn out false, so there is a Russellian alternative to the Aristotelian view, according to which future contingents all turn out false, not neither true nor false. The result: contrary to millennia of philosophical tradition, we can be open futurists without denying bivalence. (shrink)

Holmes exists is false. How can this be, when there is no one for the sentence to misdescribe? Part of the answer is that a sentence’s topic depends on context. The king of France is bald, normally unevaluable, is false qua description of the bald people. Likewise Holmes exists is false qua description of the things that exist; it misdescribes those things as having Holmes among them. This does not explain, though, how Holmes does not exist differs in cognitive content (...) from, say, Vulcan does not exist. Our answer builds on an observation of Kripke’s: even if Holmes exists, he is not in this room, for we were all born too late. (shrink)

Indeterminacy in its various forms has been the focus of a great deal of philosophical attention in recent years. Much of this discussion has focused on the status of vague predicates such as ‘tall’, ‘bald’, and ‘heap’. It is determinately the case that a seven-foot person is tall and that a five-foot person is not tall. However, it seems difficult to pick out any determinate height at which someone becomes tall. How best to account for this phenomenon is, of course, (...) a controversial matter. For example, some (such as Sorensen (2001) and Williamson (2002)) maintain that there is a precise height at which someone becomes tall and such apparent cases of indeterminacy merely reflects our ignorance of this fact. Others maintain that there is some genuine – and not merely epistemic – indeterminacy present is such cases and offer various accounts of how best to account for it. Supervaluationists (such as Keefe (2008)), for example, claim that the indeterminacy with respect to vague terms lies in their not having a single definite extension. Rather, each term is associated with a range of possible precise extensions or precisifications such that it is semantically unsettled which is the correct extension. One precisification of ‘tall’ might allow that anyone over five feet ten inches is tall, whereas another would only allow those over six foot to qualify; but no precisification will take someone who is five foot to be tall, and someone who is seven foot will count as tall on all precisifications. Thus – while someone who is seven foot will be determinately tall and someone who is five foot determinately not so – it will be indeterminate whether someone who stands at five foot eleven inches is tall. -/- Yet, it is important to stress that putative cases of indeterminacy are not limited to vague predicates of this kind. Philosophers have invoked indeterminacy in discussions of topics as diverse as moral responsibility (Bernstein (forthcoming)), identity over time (Williams (2014)), and the status of the future (Barnes and Cameron (2009)). In this paper, we focus on two areas where discussion of various kinds of indeterminacy has been commonplace: physics and fiction. We propose a new model for understanding indeterminacy across these domains and argue that it has some notable advantages when compared to earlier accounts. Treating physics and fiction cases univocally also indicates an interesting connection between indeterminacy in these two areas. (shrink)

This essay revisits some classic problems in the philosophy of space and time concerning the counting of possibilities. I argue that we should think that two Newtonian worlds can differ only as to when or where things happen and that general relativistic worlds can differ in something like the same way—the first of these theses being quaintly heterodox, the second baldly heretical, according to the mores of contemporary philosophy of physics.

This article examines Kamel Daoud’s treatment of solidarity and the absurd in Meursault, contre-enquête and posits that the question of how to live in solidarity with others is central to the novel, although the word ‘solidarity’ never appears in it. After recalling Camus’s discussion of the absurd in Le Mythe de Sisyphe and of solidarity in L’Homme révolté, the article examines the manner in which Haroun, Daoud’s narrator and the brother of the Arab Meursault killed in L’Étranger, reveals his own (...) failures of solidarity. He justly criticizes Meursault for privileging his confrontation with the absurd over the death of the Arab he did not even name, but Haroun too has killed. Haroun has, however, a greater understanding of solidarity than his fellows: he at least recognizes that murder is significant. He thus joins Meursault as an unworthy prophet who proclaims the absurd while surrounded by people who flee from it—and proclaiming the absurd can be a gesture of solidarity when one speaks for others, as Haroun speaks for his brother Moussa. Daoud’s novel reminds us that there are no final answers telling us how to live in solidarity with others and that we must do so all the same. (shrink)

In this article I offer a three-pronged defense of Millian theories, all of which share the rough idea that all there is to a proper name is its referent, so it has no additional sense. I first give what I believe to be the first correct analysis of Kripke’s puzzle and its anti-Fregean lessons. The main lesson is that the Fregean’s arguments against Millianism and for the existence of semantically relevant senses (that is, individuative elements of propositions or belief contents (...) that are sensitive to our varying personal conceptions of the referents of those elements) are viciously circular. Thus, the Fregean must give new arguments for her central claims. Second, I offer an original, positive argument for the Millian idea that the thoughts that Cicero was bald and that Tully was bald are identical. Incredibly, the argument appeals to nothing but highly intuitive, pre-theoretical principles regarding folk psychological usage—traditionally the source of Fregean intuitions. Third, I examine one of the most important recent papers on Kripke’s puzzle, that by David Sosa (1996). Sosa claims to have found a way to turn the tables on Kripke’s puzzle by using it to argue against Millian theories. I argue that Sosa’s argument on behalf of the Fregean is question-begging. I conclude that Millian theories can be seriously defended without any use of theoretical constructs such as guises or Russellian propositions, and Fregeans need to start over arguing for their theory’s central claims.

I give a new argument for the moral difference between lying and misleading. First, following David Lewis, I hold that conventions of truthfulness and trust fix the meanings of our language. These conventions generate fair play obligations. Thus, to fail to conform to the conventions of truthfulness and trust is unfair. Second, I argue that the liar, but not the misleader, fails to conform to truthfulness. So the liar, but not the misleader, does something unfair. This account entails that bald-faced (...) lies are wrong, that we can lie nonlinguistically, and that linguistic innovation is morally significant. (shrink)

This paper introduces and argues for the hypothesis that judgments of testimonial worth are central to our practice of normatively appraising speech. It is argued that judgments of testimonial worth are central both to the judgement that an agent has lied, and to the acceptance of testimony. The hypothesis that, in lying, an agent necessarily displays poor testimonial worth, is shown to resolve a new puzzle about lying, and the recalcitrant problem raised by the existence of bald faced lies, and (...) selfless assertions. It is then shown that the notion of testimonial worth allows us to capture the distinction between taking a speaker at their word, and treating them as a mere indicator of the truth in a way other theories fail to do.

Egal was der heutige Tag auch bringen mag, der 1. April 2063 wird zumindest als der Tag in die Geschichte des Wissenschaftsjournalismus eingehen, der die bisher aufwändigste Berichterstattung erfahren hat. So viele Kamerateams, wie hier vor den Toren der Australian National University in Canberra, hat bisher kein wissenschaftliches Experiment anziehen können. Selbst der Knüller des Vorjahres, als es einer 48jährigen Hausfrau in einem Vorort von London gelang, mit einfachsten Küchenutensilien einen kleinen Kalte-Fusion-Reaktor herzustellen, der den Staubsauger und die Mikrowelle zuverlässig (...) mit sauberer Energie versorgte, hatte bei weitem nicht ein solches Echo in der Wissenschaftspresse erfahren. Es war zwar noch nichts über den Experimentausgang zu erfahren, trotzdem wurde freilich seit drei Tagen ununterbrochen live auf fast allen Kanälen aus Canberra darüber berichtet, dass nun zwar noch nichts zu erfahren sei, dass es aber ja sehr bald soweit sein müsse. Das Experiment, dessen Ausgang man hier so gespannt erwartete, war schon im Vorfeld hitzig diskutiert worden und überhaupt nur durch einen Sonderbeschluss der Vereinten Nationen zustande gekommen. Immerhin läuft die Vorbereitung bereits seit fast 30 Jahren, als sich mehrere Philosophen und Bürgerinitiativen zusammenschlossen, die UNO um eine endgültige Klärung einer der ältesten Fragen der Menschheit zu bitten: Was ist Bewusstsein? Und insbesondere: Ist Bewusstsein etwas anderes als physikalisch beschreibbare Zustände unseres Gehirns, oder sind alle Tatsachen letztlich physikalische Tatsachen? Dass diese Fragen trotz ihres Ehrfurcht einflößenden Alters zunehmend auf den Nägeln brannten, hatte nicht zuletzt die jüngste Entwicklung der Computertechnologie befördert. Nachdem die KI in den letzten Jahrzehnten einen großen Schritt vorwärts gemacht hatte, war man in Sorge, dass ohne endgültige begriffliche Klärung dieser Fragen unser zukünftiger Umgang mit unseren elektronischen Helfern auf moralisch unsicherem Boden stehen könne. Man hatte sich daher nach langer Abwägung der ethischen Aspekte dieses Experiments dazu entschieden, ein gerade neugeborenes Waisenkind in einem völlig schwarz-weiß-grauen Raum groß werden zu lassen, sorgsam darum bemüht, dass die kleine Mary (so hatte man das Mädchen in Anlehnung an die Protagonistin einer fiktiven philosophischen Geschichte genannt) keine Farben zu Gesicht bekommt..

Descartes's "conceivability argument" for substance-dualism is defended against Arnauld's criticism that, for all he knows, Descartes can conceive himself without a body only because he underestimates his true essence; one could suggest with equal plausibility that it is only for ignorance of his essential hairiness that Descartes can conceive himself as bald. Conceivability intuitions are defeasible but special reasons are required; a model for such defeat is offered, and various potential defeaters of Descartes's intuition are considered and rejected. At best (...) though Descartes shows the separability of mind from body, not (as he claims) their actual separateness. (shrink)

The purpose of this paper is to propose and defend an absolute principle of truthmaking, a maximalist one according to which every truth is made true by something in the world beyond itself. I maintain that an absolute principle must be true, that any weakened version is straightforwardly contradictory or incoherent. I criticize one principle of truthmaking (in terms of bald necessity) and articulate one in terms of the relation in virtue of. I then criticize other principles of truthmaking in (...) light of the latter, for I contend that in virtue of has a role in the theory of truthmaking that is essential and ineluctable. That all true representations have a truthmaker as defined by the principle I articulate is the absolute principle of truthmaking I defend. The crux of the paper is the arguments I present in defense of this absolute principle. In defending it against familiar objections to maximalism, an account of the truthmakers that seem to ground all true representations emerges. I maintain that such truthmakers are simple facts. With the absolute principle and its corollary account of truthmakers, this paper contains the core of a comprehensive theory of truthmaking. (shrink)

Abstract: Background: Hair loss is often a concern for women, men and children. It is normal to lose between 50 and 100 hairs a day, without us noticing it. Usually hair loss is a sign of a medical condition, some of them are hereditary, and some of them are temporary due to disease, stress, cancer treatment, weight loss, and iron deficiency. Objectives: The main goal of this expert system is to obtain an appropriate diagnosis of the cause of hair loss. (...) Methods: In this paper, the proposed expert system that was produced is designed to assist the physician in diagnosing hair loss disease such as seborrhea, lichen planus, ringworm, alopecia areata, thyroid disease and male-pattern baldness. The proposed expert system presents an overview about hair loss diseases are given, the cause of diseases are outlined and the treatment of disease whenever possible is given out. Clips Expert System language was used for designing and implementing the proposed expert system. Results: The proposed hair loss diseases diagnosis expert system was evaluated by Medical students and they were satisfied with its performance. Conclusions: The Proposed expert system is very useful for hair loss treatment physician, patients with hair loss problems and newly graduated physician. (shrink)

For a certain ordinary class of desires, Marcel Proust’s thoughts on their satisfaction can be summed up in one word: don’t. Don’t satisfy your desires; doing so will fail to satisfy you. Should you therefore seek to eliminate desire? Absolutely not: desiring itself sustains you. The disappointment of attaining what you desire is one of Proust’s most persistent themes, elaborated in the florid unfolding of À la recherche du temps perdu but already expressed succinctly in an early story from Les (...) plaisirs et les jours: “Desire makes all things blossom; possession wilts them.” If you believed this, what should you do? Best to aim not to satisfy your desires at all. This paper is a development and limited defense of these baldly stated claims, and includes discussions of the role of the imagination in the formation of desire, the distinction between the hypothetical imagination and the imaginativeness that is involved in the perception of beauty, and the relationship between desire, desire satisfaction, and agent satisfaction.

People espousing human moral equality encompassing every conspecific have been unumbrageous being labeled ‘speciesists’ and likened to Nazis and Klansmen, despite the insult’s being indefensible, and, if meant seriously, enraging. Perhaps their equanimity is unruffled because anti-speciesist acquaintances are remarkably chummier with them than with real racists. -/- Anti-speciesists confuse two questions: (1) Is the bare fact of an individual’s being a human in itself a reason for us humans to deal with it as we'd like to be dealt with? (...) (2) Have we enough reason, apart from human well-being, to impose on each other protections of other animals? Speciesism, perspicuously specified, says ‘yes’ to (1) and nothing about (2). World-wide, human fantasy is filled with nonhuman persons, alien morally accountable agents, thought worthy of being treated as we would wish to be treated, or better. The idea of human equality is consistent with both rapaciously using animals and radical animal protectionism. We meat-eaters discount animal interests, not because they’re nonhuman, but because we know no compelling reason to count them more. -/- Anti-speciesist literature is surveyed and seen to specify ‘speciesism’ capriciously. Terminology aside, anti-speciesist criticisms are specious. Anti-speciesists hope to shift the justificatory burden by denying species membership any moral relevance, but that denial cannot motivate their protectionism. Their ad hominem dismissal of speciesism as a self-serving prejudice is unsustainable. Their avowed inability to imagine any justification of speciesism is hardly probative. Their alleged refutations are baldly question-begging assertions of theses of hallowed ethical theories speciesism denies. They derive anti-speciesism from “anti-biologism” (a radical denial of any biological relation’s having any intrinsic moral relevance), which is fallaciously extrapolated from anti-racist and anti-sexist ideas. Appeals to taxonomical controversies glibly and disingenuously assume the relevance of those controversies, which anti-biologism denies. (shrink)

Ancient Greek philosophers were the first to postulate the possibility of explaining nature in theoretical terms and to initiate attempts at this. With the rise of monotheistic religions of revelation claiming supremacy over human reason and envisaging a new world to come, studies of the natural order of the transient world were widely considered undesirable. Later, in the Middle Ages, the desire for human understanding of nature in terms of reason was revived. This article is concerned with the fundamental reversal (...) of attitudes, from "undesirable" to "desirable", that eventually led into the foundations of modern science. One of the earliest, most ingenious and most interesting personalities involved was Eriugena, a theologian at the Court of Charles the Bald in the 9th century. Though understanding what we call nature is only one of the several aspects of his philosophical work, his line of thought implies a turn into a pro-scientific direction: the natural order is to be understood in abstract terms of "primordial causes"; understanding nature is considered to be the will of God; man encompasses the whole of creation in a physical as well as a mental sense. Basically similar ideas on the reconciliation of scientific rationality and monotheistic religions of revelation were conceived, independently and nearly simultaneously, by the Arab philosopher al-Kindi in Bagdad. Eriugena was more outspoken in his claim that reason is superior to authority. This claim is implicit in the thought of Nicholas of Cusa with his emphasis on human mental creativity as the image of God's creativity; and it is the keynote of Galileo's "Letter to the Grand Duchess Christina" some 800 years later, the manifesto expressing basic attitudes of modern science.

There are four ways in which things are said to oppose (ἀντικεῖσθαι) each other: as relatives (τὰ πρός τι), as contraries (τὰ ἐναντία), as privation and possession (στρέσις καὶ ἓξις) and as affirmation and negation (κατάφασις καὶ ἀπόφασις). (Cat. , 10, 11b15-23) Aristotle’s examples are: double and half for relatives, good and bad for contraries, blindness and sight for privation and possession and ‘He is sitting’ and ‘he is not sitting’ for affirmation and negation. We discussed relatives separately thus we (...) ignore it here. A. Contraries Contraries (ἐναντία) have the following features: 1) They are not said of each other (οὐδαμῶς πρὸς ἄλληλα λέγεται) as relatives are said of each other. (Cat., 10, 11b15-23) 2) Contraries are of two kinds: a) Non-intermediables: Those that it is necessary for one or the other of them to belong to the things they naturally occur in or predicated of and accept no intermediate between themselves. Since it is necessary for one of e.g. health and sickness to occur in an animal’s body or odd and even to belong to a number, there is no intermediate between health and sickness or odd and even. (Cat., 10, 11b38-12a9; 12b28-34) b) Intermediables: Those that it is not necessary for one of them to belong to the things they naturally occur in or predicated of and accept intermediates between themselves. It is not necessary for one of e.g. black and white to belong to a body and there may be some intermediates between them. (Cat., 10, 12a9-25; 12b34-40) 3) Contraries can change to one another when the thing capable of receiving them is there. (Cat., 13a18-21) The only exception is when one of the contraries belongs to something by nature. In such cases, change is not possible as the hotness of fire cannot change to coldness while fire is still there. 4) Contraries belong to the same thing, either the same in species or in genus as e.g. sickness and health in an animal’s body or whiteness and blackness in body simply. (Cat., 10, 14a15- ) In Metaphysics (I, 1058a8-10) Aristotle asserts that contraries are in the same genus. 5) There are three possibilities about the genera of contraries: they either are in the same genus, e.g. black and white, or in the contrary genera, e.g. justice and injustice, or are themselves genera, e.g. good and bad. (Cat., 11, 14a19-25) 6) Doing and being affected admit of contrariety, e.g. heating is contrary to cooling. (Cat., 9, 11b1-4) 7) Substances only are able to receive contraries. (Cat., 5, 4a10-17) 8) There is nothing contrary to a substance, whether primary or secondary. (Cat., 5, 3b24-27) Thus, neither man nor an individual man has a contrary. 9) There is no contrary to a quantity: e.g. four-foot ot ten has no contrary. (Cat., 5, 3b27-32) 10) Otherness in species means to be contraries. (Met., I, 1058a17-20) 11) Contrariety is complete difference. Two things that have the same genus but are different in species are other than one another in the highest degree and their difference is complete, i.e. they cannot be present along with one another. (Met., I, 1058a10-16) 12) One of the contraries is a privation, which is a denial of a predicate to a determinate genus. (Met., Γ, 1011b18-20) 13) ‘Neither true judgments nor true propositions can be contrary the one to the other.’ (OI., II, 14, 24b6-7) B. Privation and possession Privation and possession are said in connection with the same thing in which the possession naturally occurs. Only that thing which is capable of receiving a possession and only when it is entirely absent from that which naturally has it and only at the time when it is natural for it to have it, is called to be deprived of it. (Cat., 10, 12a26-30) A thing is not called e.g. blind if it has never had or was not supposed to have sight. That privation and possession are not relatives is obvious from the fact that none is called just what it is, of its opposite. (Cat., 10, 12b16-21) Moreover, while relatives reciprocate, they do not. (Cat., 10, 12b21-25) That they are not contraries is explained by the classification of contraries to intermediable and non-intermediable contraries. The latter are different from privation and possession because it is necessary for one of such contraries to be predicated of absolutely everything while it is not the case about privation and possession because they are necessary only in things naturally capable of their predication. Intermediable contraries are different from privation and possession because while the former are not necessary the latter are necessary in their subject matters. (Cat., 13a3-17) Unlike contraries for each of which it is possible to change to the other, change in privation and possession is allowed only from possession to privation and not vice versa: neither a blind man gets sight nor a bald man regain his hair. (Cat., 13a18-36) C. Affirmation and negation Aristotle regards the reception of truth and falsity as the main difference affirmation and negation opposition has in respect of other three kinds of opposition: it is only affirmation and negation that it is always necessary for one of them to be true and the other to be false (Cat., 13a37-b26), no matter the subject of affirmation or negation exists or not. (Cat., 10, 13b27-35) ‘It is impossible that contradictory propositions should both be true of the same subject.’ (OI., II, 12, 21b17-18) It is evident both about relatives and those contraries that include no co-positing, e.g. health and sickness. The only cases that resemble affirmation and negation are those contraries that are said with co-positing, e.g. ‘Socrates is well’ and ‘Socrates is sick.’ Yet, Aristotle points, not even with these is it necessary always for one to be true and the other false because if Socrates does not exist, neither will be true. (Cat., 10, 13b12-19) This is true also about privation and possession: neither ‘Socrates has sight’ nor ‘Socrates is blind’ are true if he does not exist. Moreover, it is not necessary for one or the other of them to be true or false even if he exists because until the time when it is natural for Socrates to have sight, both are false. (Cat., 10, 13b20-26) . (shrink)

The epistemic regress problem targets our ability to provide reasons for our beliefs. If we need reasons for our beliefs, then we may also need to provide reasons for those reasons, and so on into regress. Because the epistemic regress problem is often cast as an attack on our ability to achieve justification, it is often thought that epistemic positions which do not rely on notions like justification escape without difficulty. The first goal of this dissertation is to establish the (...) generality of the epistemic regress problem, beyond all technicalities regarding the nature of justification. To do this, I propose a new minimal epistemic standard, that we should hold no bald assertions to be epistemically acceptable. I then use this epistemic standard to construct two new forms of the epistemic regress problem. The first version of the problem is reminiscent of the classical problem in that it attacks our ability to locate any such reason. The second version of the problem attacks our ability to unite any such reason to a particular claim that it is supposed to support. The second goal of this dissertation is to argue that pragmatism fails as a solution to the epistemic regress problem. The pragmatist seeks to avoid the regress by provisionally accepting their beliefs to be evaluated later. In so doing, the pragmatist seeks to have reasonable beliefs, but only after having accepted them provisionally. After eliminating other theoretical alternatives that the pragmatist may use to bolster their position, I argue that the pragmatic solution is not successful because (1) it is committed to some foundational beliefs that are necessary to facilitate the evaluation of their provisional beliefs which fall prey to the regress, and (2) the employment of these criteria of evaluation encounters the regress in its second form. I conclude by advocating for an understanding of Pyrrhonian skepticism under which we are not required to eschew our everyday beliefs that is nevertheless commensurate with the epistemic regress.

Contrary to the great bulk of philosophical work on vagueness, the core of vagueness is not to be found in vague monadic predicates such as ‘bald’, ‘tall’, or ‘old’. The true source of vagueness – at least vagueness of the type that typically appears in the sorites – lies beneath these, in a mechanism using a buried quantifier operative over the comparatives ‘balder’, ‘taller’ and ‘older’.

"Jim would still be alive if he hadn't jumped" means that Jim's death was a consequence of his jumping. "x wouldn't be a triangle if it didn't have three sides" means that x's having a three sides is a consequence its being a triangle. Lewis takes the first sentence to mean that Jim is still alive in some alternative universe where he didn't jump, and he takes the second to mean that x is a non-triangle in every alternative universe where (...) it doesn't have three sides. Why did Lewis have such obviously wrong views? Because, like so many of his contemporaries, he failed to grasp the truth that it is the purpose of the present paper to demonstrate, to wit: No coherent doctrine assumes that statements about possible worlds are anything other than statements about the dependence-relations governing our world. The negation of this proposition has a number of obviously false consequences, for example: all true propositions are necessarily true (there is no modal difference between "2+2=4" and "Socrates was bald"); all modal terms (e.g. "possible," "necessary") are infinitely ambiguous; there is no difference between laws of nature (e.g. "metal expands when heated") and accidental generalizations (e.g. "all of the coins in my pocket are quarters"); and there is no difference between the belief that 1+1=2 and the belief that arithmetic is incomplete. Given that possible worlds are identical with mathematical models, it follows that the concept of model-theoretic entailment is useless in the way of understanding how inferences are drawn or how they should be drawn. Given that the concept of formal-entailment is equally useless in these respects, it follows that philosophers and mathematicians have simply failed to shed any light on the nature of the consequence-relation. Q's being either a formal or a model-theoretic consequence of P is parasitic on its bearing some third, still unidentified relation to P; and until this relation has been identified, the discipline of philosophical logic has yet to begin.

PRINCÍPIOS DA DIGESTÃO DOS ALIMENTOS NOS BEZERROS -/- -/- E. I. C. da Silva -/- Departamento de Agropecuária – IFPE Campus Belo Jardim -/- Departamento de Zootecnia – UFRPE sede -/- -/- PRINCÍPIOS DA DIGESTÃO DOS ALIMENTOS NOS BEZERROS -/- -/- INTRODUÇÃO -/- Se todos os bezerros pudessem ser criados por suas mães, haveria pouca necessidade de inúmeros livros, artigos e trabalhos, como esse, sobre a criação e o manejo básico desses animais. A maioria das vacas desempenha um ótimo papel (...) na criação dos seus descendentes, desde que sejam tomados os devidos cuidados com relação a alimentação, saúde e a outros aspectos relativos à criação desses neonatos. A essência da pecuária bovina relativa à criação de bezerros é manter esses animais vivos e aptos o suficiente para desempenhar atividades produtivas de grande importância na propriedade. Para tanto, os criadores necessitam entender o desenvolvimento do trato digestivo do bezerro e os conceitos básicos da digestão dos alimentos por ele, e é isso que pretendo aclarar de forma clara e concisa com esse trabalho. -/- -/- 1.1 O TRATO DIGESTIVO DO BEZERRO -/- Um animal adulto necessita de quatro estômagos funcionais para dar-lhe a capacidade de utilizar a ampla gama de alimentos disponíveis. -/- O retículo e o rúmen abrigam milhões de micróbios que fermentam e digerem o material vegetal, em especial às presentes nas forragens. O omaso permite a absorção de água do conteúdo do intestino. O abomaso, ou quarto estômago, é o verdadeiro estômago, comparável ao dos humanos, e permite a digestão ácida dos alimentos. -/- O bezerro muito jovem não desenvolve a capacidade de digerir o pasto, sendo assim o abomaso é o único estômago funcional ao nascer. Tanto os animais recém-nascidos como os adultos têm um intestino delgado funcional que permite a digestão alcalina dos alimentos. -/- A figura 1 ilustra a anatomia dos estômagos e intestino delgado de um bezerro recém-nascido. Esse diagrama esquemático mostra as dimensões relativas dos quatro estômagos, o sulco esofágico, que vai do esôfago até o abomaso, e o esfíncter pilórico ou válvula no fundo do abomaso, que controla a velocidade de movimento do conteúdo do intestino no duodeno. -/- O omaso e o abomaso representam cerca de 70% da capacidade total do estômago no bezerro recém-nascido. Por outro lado, nas vacas adultas, eles compõem apenas 30% da capacidade total do estômago (figura 2). -/- A digestão dos alimentos é auxiliada pela secreção de certos produtos químicos denominados enzimas, que estão presentes nas várias partes do intestino. Por exemplo, os bezerros produzem a enzima renina na parede do abomasal para auxiliar na digestão das proteínas do leite, enquanto a lactase é produzida na parede do duodeno para a digestão do açúcar do leite (lactose). Estas enzimas operam mais eficazmente em diferentes níveis de acidez no conteúdo do intestino, ácido no abomaso e alcalino no duodeno. Para conseguir isso, o bezerro segrega eletrólitos, ou sais minerais, com as enzimas, para mudar o conteúdo do intestino de um tipo para outro. -/- Os produtos finais da digestão dos diferentes componentes dos alimentos são absorvidos através da parede do intestino, mediante as vilosidades intestinais, para a corrente sanguínea, onde são levados para as diferentes partes do corpo para o crescimento e desenvolvimento do animal. -/- -/- 1.2 O BEZERRO ALIMENTADO COM LEITE -/- O Leite ou substituto do leite, quer seja apreendido através de uma teta ou bebido de um balde, é canalizado do esôfago através do sulco esofágico para o abomaso. Este sulco é um pequeno canal na parede do rúmen que é controlado por músculos que permitem que os líquidos sejam diretamente enviados para o abomaso e que não entrem no rúmen. O sulco é ativado em resposta a diferentes estímulos. Funciona bem quando os bezerros amamentam-se através das tetas das mães, mas às vezes não funciona quando bebem de um balde. Essa parece ser uma condição psicológica em resposta aos bezerros separados de suas mães. A maioria dos bezerros podem ser treinados pelo tratador para beber o leite do balde rapidamente e bem, a metodologia empregada é a da persuasão do animal, ao qual o mesmo possa responder positivamente à nova rotina diária e à mãe substituta na forma do criador do bezerro. Quando o leite ou o substituto do leite entra no abomaso, forma um coágulo firme dentro de alguns minutos sob a influência das enzimas renina e pepsina. Este é o mesmo processo envolvido na fabricação de queijo ou junket, usando renina para coagular a proteína do leite. A coagulação do leite retarda a taxa em que flui para fora do abomaso, permitindo assim uma liberação constante de nutrientes alimentares em todo o intestino e, eventualmente, para a corrente sanguínea. Pode levar de 12 a 18 horas para que a coalhada de leite seja totalmente digerida. -/- As enzimas que atuam nas proteínas do leite requerem um ambiente ácido e esse é fornecido pela secreção do ácido clorídrico no abomaso. No entanto, até que a digestão ácida esteja operando de forma eficiente, e isso pode levar até sete dias, a única forma de proteína que pode ser digerida é a caseína. Não há substituto para a caseína no bezerro muito jovem. Os substitutos do leite que contêm outras formas de proteína não podem ser devidamente digeridos até que os bezerros sejam mais velhos. Logo, é necessário muito cuidado para não fornecer substitutos ou sucedâneos que contenham fontes proteicas que não possam ser digeridas pelo estômago do animal, para que não ocasione complicações gastrintestinais. -/- A digestão do leite pode ser melhorada com a inclusão de coalho, que pode ser obtido a partir de fábricas de queijo ou aditivos comerciais de leite de bezerro para a primeira semana ou mais. Esses produtos comerciais podem fornecer ácidos adicionais para reduzir o pH abomasal e incrementar a quantidade de enzimas e bactérias específicas para aumentar a taxa de degradação da coalhada de leite. Tais aditivos são chamados probióticos, na medida em que ajudam nos processos digestivos normais. A pesquisa nem sempre os encontrou para melhorar o desempenho e a saúde dos bezerros, e eles são mais propensos a ser benéficos quando os bezerros estão sofrendo de problemas de saúde. Além disso, a sua eficácia, em termos de custo-benefício é, por vezes, questionada. -/- Qualquer leite de uma alimentação anterior está envolvido neste coágulo recém-formado. As proteínas líquidas de soro de leite e a lactose são rapidamente separadas da coalhada de leite e passam para o abomaso. A gordura do leite contida na coalhada de leite é decomposta por outra enzima, a lipase. Esta é secretado na boca pela saliva e incorporada quando o leite é engolido. A alimentação pelas tetas em vez da alimentação através do balde parece produzir mais saliva e, portanto, mais lipase. A digestão adicional da proteína do leite e da gordura ocorre no duodeno com a ajuda das enzimas produzidas no pâncreas. -/- A lactose, que é rapidamente liberada da coalhada de leite no abomaso, é dividida em glicose e galactose e estas são absorvidas na corrente sanguínea para formar a principal fonte de energia para os bezerros jovens. -/- As gorduras são divididas em ácidos graxos e glicerol para absorção e uso como energia, enquanto as proteínas são divididas em aminoácidos e peptídeos para absorção e uso como fontes de proteína corporal. -/- O amido de cereais, por exemplo, é uma importante fonte de energia em bezerros mais velhos, mas esses animais, nas suas primeiras semanas de vida, não conseguem digerir o amido. -/- O abomaso não é ácido até que o bezerro tenha 1-2 dias de idade e isso apresenta vantagens e desvantagens. A principal vantagem é que as proteínas imunes no colostro não podem ser digeridas nesse compartimento estomacal, por isso são absorvidas na corrente sanguínea na mesma forma quando produzidas pela vaca. Isso garante o seu papel como anticorpos para proteger contra as doenças e infecções. A baixa acidez do conteúdo abomasal no bezerro recém-nascido constitui um risco potencial das bactérias (e provavelmente vírus) tomadas através da boca. Estes não serão mortos pela digestão ácida, sendo assim podem passar para os intestinos, onde podem fazer mal ao bezerro recém-nascido. -/- Todos os bezerros pegam bactérias nos primeiros dias de vida e isso é essencial para o desenvolvimento normal do rúmen (flora microbiana). No entanto, a primeira bactéria a colonizar o intestino também pode causar danos. Desde que o bezerro tenha bebido colostro, os anticorpos maternos podem controlar a propagação dessas bactérias mais nocivas. -/- O bezerro alimentado com leite deve, então, produzir uma digestão ácida no abomaso e uma digestão alcalina no duodeno. Isto é conseguido pela produção de eletrólitos na parede do intestino. -/- Bezerros que sofrem de escoriações devido a distúrbios nutricionais ou infecções bacterianas podem perder grandes quantidades de água e eletrólitos em suas fezes. Estes devem ser reabastecidos como parte do tratamento para as escoriações. -/- O colostro é o primeiro leite produzido por vacas recém-paridas. Além de fornecer nutrientes essenciais para a alimentação animal, fornece anticorpos maternos que permitem a transferência passiva de imunidade contra doenças. As recomendações para a alimentação com colostro serão abordadas brevemente em outro trabalho. -/- -/- 1.3 DESENVOLVIMENTO DO RÚMEN E O PROCESSO DE DESMAME -/- Quando os bezerros são desmamados, o custo da criação diminui acentuadamente. Os custos de alimentação são mais baixos, os insumos de trabalho são reduzidos e a incidência de problemas de saúde é menor. No sentido econômico, faz sentido desmamar os bezerros assim que for razoável. No entanto, o bezerro é forçado a sofrer várias mudanças dramáticas, a saber: -/-  A fonte primária de nutrientes muda de líquido para sólido. -/-  A quantidade de matéria seca que o bezerro recebe é reduzida. -/-  O bezerro deve adaptar-se de um tipo monogástrico a um ruminante de digestão, que inclui a fermentação de alimentos. -/-  Mudanças na habitação e no manejo muitas vezes ocorrem em torno do desmame, o que pode aumentar o estresse. -/- Ao nascer, o rúmen é uma parte pequena e estéril do intestino que, ao desmame deve se tornar o compartimento mais importante dos quatro estômagos. Deve aumentar em tamanho, atividade metabólica interna e fluxo sanguíneo externo. Os cinco requisitos para o desenvolvimento ruminal são: -/-  Estabelecimento de bactérias. -/-  Líquido. -/-  Saída de material (ação muscular). -/-  Capacidade absortiva do tecido. -/-  Substrato para permitir o crescimento bacteriano, tais como minerais reciclados, bem como nutrientes para alimentação. -/- Antes do consumo de alimentos sólidos, as bactérias existentes fermentam o cabelo ingerido, o estrato e o leite que flui do abomaso para o rúmen. A maior parte da água que entra no rúmen provém da água livre (água real não contida no leite ou na solução substituta do leite). O leite contornará o rúmen através do sulco esofágico, enquanto a água livre não. -/- O rúmen se desenvolve a partir de um órgão muito pequeno em bezerros recém-nascidos (1-2 L) para a parte mais importante do intestino (25-30 L) por 3 meses de idade. Ele pode aumentar muito rapidamente durante as primeiras semanas de vida, dado o manejo da alimentação direita. -/- O crescimento do rúmen ocorre apenas sob a influência dos produtos finais da digestão no mesmo, que resultam da fermentação de alimentos sólidos pelos micróbios presentes nesse compartimento. O desenvolvimento ocorre em grande parte através do crescimento das papilas ruminais (figura 5 e 6) na parede ruminal (estruturas semelhantes a folhas na superfície interna), que aumentam a área superficial do rúmen e, portanto, a sua capacidade de absorver estes produtos finais de digestão. Portanto, os concentrados favorecem melhor o desenvolvimento dessas papilas ruminais. Para tanto, é necessário, com um tempo, ir incrementando a dieta sólida gradativamente para que esses animais deixem de consumir o leite das vacas produtoras e possam alimentar-se de ração e pastagens, que é a finalidade da criação de bovinos, ou seja, criar animais com menor custo possível e engordá-los através de ração, mas principalmente de pastagens. -/- A capacidade do rúmen e a ingestão de alimentos sólidos estão intimamente relacionadas. O desenvolvimento do rúmen é muito lento em bezerros alimentados com grandes quantidades de leite. O leite satisfaz seus apetites para que eles não tenham fome suficiente para comer qualquer alimento sólido. Logo, é necessário diminuir paulatinamente o fornecedor do leite para esses animais, favorecendo a ingestão de alimentos sólidos e desenvolvendo o rúmen, estômago que digere as fibras das forragens e que os tona animais peculiares. -/- A ruminação pode ocorrer com cerca de 2 semanas de idade e é uma boa indicação de que o rúmen está se desenvolvendo. Alimentos sólidos, bem como a ruminação, estimulam a produção de saliva e isso fornece nutrientes como ureia e bicarbonato de sódio para produzir os substratos para o crescimento e desenvolvimento da flora bacteriana. -/- No desmame precoce, é importante limitar a quantidade de leite oferecida e a sua disponibilidade durante todo o dia. Também é essencial fornecer alimentos sólidos. Os grosseiros (de baixa ou alta qualidade) devem ser oferecidos em combinação com concentrados de alta qualidade. -/- O criador deve tomar cuidado com o fornecimento de alimentos como a ração farelada, uma vez que essa ração pode entrar pelas vias nasais e ocasionar complicações respiratórias; há alguns relatos de bezerros mortos após a ingestão de ração farelada, na autópsia de um dos casos foi diagnosticada uma morte por esses grãos farelados presentes no pulmão. Portanto, para evitar complicações o ideal é que se forneça uma ração denominada peletizada. -/- Os alimentos grosseiros (volumosos) estimulam o desenvolvimento do rúmen, enquanto os concentrados fornecem nutrientes para a alimentação animal que não são fornecidos pelas quantidades limitadas de leite oferecidas. Sem os concentrados, o crescimento dos bezerros é lento, mas o rúmen ainda se desenvolve, resultando em animais barrigudos. -/- A ureia fornece nitrogênio para os micróbios, enquanto o bicarbonato de sódio atua como um tampão ruminal, ajudando a manter um pH estável no conteúdo do rúmen. Isso é, particularmente, importante quando os bezerros comem grandes quantidades de grãos de cereais na vida adulta, pois os micróbios do rúmen podem produzir muito ácido lático durante a fermentação desse material. -/- Envenenamento por grãos ou acidose ocorre quando os níveis de ácido lático são excessivamente elevados e tornam-se tóxicos para os micróbios do rúmen e, eventualmente, para o animal. Assim como os produtos finais que são absorvidos através da parede do rúmen, a fermentação microbiana produz os gases dióxido de carbono e metano e estes são normalmente exalados. Quando algo impede a fuga destes gases do rúmen, o inchaço pode se manifestar em qualquer fase da vida, diz-se do animal estufado. -/- -/- 1.4 O PAPEL DA FORRAGEM NO PROCESSO DE DESMAME -/- Existem inúmeras controvérsias acerca do papel da forragem no processo de desmame. Pesquisas realizadas na década de 1980 indicaram claramente que a forragem era benéfica, enquanto pesquisas da década de 1990 descobriram que nem sempre era necessário o fornecimento da forragem para que os bezerros fossem desmamados e que não sofresse estresse e nem apresentasse baixa eficiência produtiva e reprodutiva no futuro. Na maioria das pesquisas anteriores, os bezerros eram desmamados com a oferta de concentrados moídos como pellets com ou sem a presença de feno longo ou palha. Porém, a inclusão de forragens na dieta melhorou a ingestão e o desempenho, além de permitir o desmame precoce. -/- Na pesquisa posterior, os bezerros geralmente alimentavam-se de concentrados grosseiramente moídos, além de alguns volumosos, enquanto alguns até incluíam volumosos picados finos na mistura (às vezes chamados de mistura muesli por apresentar o capim e a ração). Nesses estudos, verificou-se que a inclusão de feno ou palha adicional teve pouco efeito no desempenho pré-desmame. -/- Os sistemas de criação de bezerros australianos frequentemente diferem dos demais, especialmente em áreas de parto sazonais. Um número excessivo elevado de bezerros precisam ser criados de uma só vez para lhes fornecer, a todos, currais individuais durante todo o seu período de amamentação. Consequentemente, os bezerros são criados em grupos. Além disso, os ingredientes da maioria dos concentrados para esses animais são finamente moídos. Nessas situações, descobriu-se que a palha limpa é um alimento útil e que deve ser incluso no período pré-desmame. Alguns agricultores preferem feno de boa qualidade, porém estes agricultores geralmente têm bezerros em grupos muito pequenos, muitas vezes um ou dois, por isso possuem maior controle sobre a ingestão de forragem. -/- Figura 7: A alimentação volumosa de bezerros alimentados com leite é uma questão controversa. Imagem cedida pelo IPA -/- É difícil e, portanto, mais caro que os produtores de rações incorporem feno picado nas refeições dos bezerros. Os pellets são muito mais fáceis, pois eles vão fluir para silos. Por fim, os produtores de leite devem incluir o componente volumoso no regime alimentar pré-desmame. A pastagem não é a fonte ideal de forragem volumosa para os bezerros alimentados com leite, uma vez que possui muito pouca fibra e uma baixa densidade de energia alimentar. O seu elevado teor de água limita a sua capacidade de fornecer energia alimentar adequada aos animais em crescimento. Para ingerir a pastagem a capacidade ruminal deveria ser maior, bezerros jovens simplesmente não conseguem comer pasto suficiente, a menos que seja de alta em qualidade. -/- Os bezerros criados com leite e fornecimento gradual de concentrados apresentam uma boa função ruminal às 3 semanas de vida, além de possuírem uma suficiente capacidade ruminal para o desmame entre às 4-6 semanas de idade. No entanto, se a dieta for baseada em leite restrito e pastagem de alta qualidade, a capacidade do rúmen pode não ser suficiente para o desmame até às 8-10 semanas de vida. Mesmo assim, as taxas de crescimento seriam menores em bezerros desmamados com base alimentar somente à pasto, uma vez que a ingestão de energia é insuficiente devido às limitações físicas da capacidade ruminal. -/- Se a qualidade for muito boa e produza apetite, os bezerros preferem volumosos ao invés do concentrado, o que leva a uma ingestão reduzida de nutrientes durante alimentação, tendo como efeito um crescimento mais lento. Quando volumosos e concentrados fornecem apetite no animal, juntamente com o leite limitado, os bezerros podem comer cerca de 10% de palha e 90% de concentrados. Sem o volumoso e a ruminação resultante, o desenvolvimento do rúmen será mais lento devido à falta de saliva e produtos finais da digestão de fibras presentes na parede celular das forragens. -/- -/- REFERÊNCIAS BIBLIOGRÁFICAS -/- -/- BEN ASHER, Aharon.

The 1830s and 1840s saw the proliferating usage of “the Beyond” (Jenseits) as a choice term for the afterlife in German public discourse. This linguistic innovation coincided with the rise of empiricism in natural science. It also signaled an emerging religious debate in which bald challenges to the very existence of heaven were aired before the wider German public for the first time. Against the belief of many contemporaries that empirical science was chiefly responsible for this attack on one of (...) the central tenets of Christianity, this essay shows instead that the role played by Christian dissenters in the negation of the Beyond. The polemical invocation of an empty Beyond coincided with the separation in the mid 1840s of two dissenting sects – the Deutschkatholiken (“German Catholics”) and the Protestant Free Congregations – from the main Christian Churches. During the Revolution of 1848, these sects, later known as Free Religious Congregations, deepened their critique of the Beyond as they articulated a new creed of radical humanism and natural scientific monism. Yet, despite their secularist agenda the Free Religious failed to fully secularize. The essay concludes by suggesting that the anticlerical activity of the Free Religious and affiliated freethinking organizations, which lasted into the 1930s, marks a century in which movements of radical political and social dissent remained open to and indeed partially dependent on the negation of the Beyond in order to sacralize humanity and nature.

Though hair loss (alopecia) is not a debilitating or life threatening sickness, the very thought of becoming bald can lead to emotional stress and traumatic experience for those who suffer from premature or excessive hair loss. Many will try anything and everything to bring back their locks. Or at least, some of their once full head of hair. Hair loss sufferers spend billions of dollars annually on remedies ranging from drugs, vitamins to special tonics and shampoos. Conventional treatments of hair (...) thinning includes drugs therapy and hair transplant. Minoxidil and Propecia (Finasteride) are the only two drugs approved by the FDA for hair growth in men. Minoxidil is the only drug available for women with and rogenetic alopecia. These drugs have been proven to show positive results for balding conditions on the vertex region of the scalp. Though these drugs are effective, many are wary of their unknown long-term effect and potential side-effects. This has led to increase interest in alternative remedies such as herbal medicine.

Amerika und die Welt befinden sich im Prozess des Zusammenbruchs durch übermäßiges Bevölkerungswachstum, das meiste davon im letzten Jahrhundert und jetzt alles aufgrund der Menschen in der 3. Welt. Der Verbrauch von Ressourcen und die Hinzufügung von ein oder zwei Milliarden weiteren etwa 2100 wird die industrielle Zivilisation zusammenbrechen und Hunger, Krankheit, Gewalt und Krieg in einem erschütternden Ausmaß herbeiführen. Milliarden werden sterben, und ein Atomkrieg ist so gut wie sicher. In Amerika wird dies durch massive Einwanderung und Reproduktion von (...) Einwanderern enorm beschleunigt, verbunden mit Missbräuchen, die durch die Demokratie ermöglicht werden. Die verdorbene menschliche Natur verwandelt den Traum von Demokratie und Vielfalt unaufhaltsam in einen Alptraum von Verbrechen und Armut. Die Hauptursache des Zusammenbruchs ist die Unfähigkeit unserer angeborenen Psychologie, sich an die moderne Welt anzupassen, was dazu führt, dass Menschen nicht verwandte Personen behandeln, als hätten sie gemeinsame Interessen. Dies, plus Unwissenheit über grundlegende Biologie und Psychologie, führt zu den Social-Engineering-Wahnvorstellungen der teilweise Gebildeten, die demokratische Gesellschaften kontrollieren. Nur wenige verstehen, dass, wenn Sie einer Person helfen, jemand anderem zu schaden – es gibt kein kostenloses Mittagessen und jeder einzelne Gegenstand, den jemand konsumiert, zerstört die Erde unwiederbringlich. Folglich ist die Sozialpolitik überall unhaltbar, und eine nach der anderen werden alle Gesellschaften ohne strenge Kontrolle des Egoismus in Anarchie oder Diktatur zusammenbrechen. Ohne dramatische und sofortige Veränderungen gibt es keine Hoffnung, den Zusammenbruch Amerikas oder eines Landes, das einem demokratischen System folgt, zu verhindern. Daher mein Essay "Suicide by Democracy". Es ist jetzt auch klar, dass die sieben Soziopathen, die China regieren, den 3. Weltkrieg gewinnen, und so mein abschließender Essay über sie. Die einzige größere Bedrohung ist Künstliche Intelligenz, auf die ich kurz eingehe. Der Schlüssel zu allem, was uns betrifft, ist die Biologie, und sie ist die Vergessenheit, die Millionen kluger gebildeter Menschen wie Obama, Chomsky,Clinton, die Demokratische Partei und den Papst dazu bringt, selbstmörderische utopische Ideale zu vertreten, die unaufhaltsam direkt in die Hölle auf Erden führen. Wie W bemerkte, ist es das, was immer vor unseren Augen ist, das am schwersten zu sehen ist. Wir leben in der Welt des bewussten deliberativen linguistischen Systems 2, aber es ist unbewusstes, automatisches reflexives System 1, das regiert. Dies ist die Quelle der universellen Blindheit, die von Searles The Phenomenological Illusion (TPI), Pinker es Blank Slate und Tooby and Cosmides' Standard Social Science Model beschrieben wird. Die erste Gruppe von Artikeln versucht, einen Einblick in unser Verhalten zu geben, das einigermaßen frei von theoretischen Wahnvorstellungen ist. In den nächsten drei Gruppen beeinetiere ich drei der wichtigsten Wahnvorstellungen, die eine nachhaltige Welt verhindern – Technologie, Religion und Politik (genossenschaftliche Gruppen). Die Leute glauben, dass die Gesellschaft durch sie gerettet werden kann, also gebe ich einige Vorschläge im Rest des Buches, warum dies unwahrscheinlich ist, durch kurze Artikel und Rezensionen von aktuellen Büchern von bekannten Schriftstellern. Ein anderer Abschnitt beschreibt den religiösen Wahn – dass es eine Supermacht gibt, die uns retten wird. Der nächste Abschnitt beschreibt die digitalen Wahnvorstellungen, die die Sprachspiele von System 2 mit den Automatismen von System eins verwechseln und daher biologische Maschinen (d. h. Menschen) nicht von anderen Maschinentypen (d. h. Computern) unterscheiden können. Andere digitale Wahnvorstellungen sind, dass wir vor dem reinen Bösen (Selbstsucht) von System 1 durch Computer/AI/Robotik/Nanotechnologie/Gentechnik, die von System 2 geschaffen wurden, gerettet werden. Der No Free Lunch-Prinzipal sagt uns, dass es ernste und möglicherweise tödliche Folgen geben wird. Der letzte Abschnitt beschreibt the One Big Happy Family Delusion, d.h., dass wir für die Zusammenarbeit mit allen ausgewählt werden und dass die euphonious Ideale von Demokratie, Vielfalt und Gleichheit uns in die Utopie führen werden, wenn wir die Dinge einfach richtig handhaben (die Möglichkeit der Politik). Auch hier sollte uns das Prinzip "Kein freies Mittagessen" warnen, dass es nicht wahr sein kann, und wir sehen in der geschichteten und ganzen heutigen Welt, dass ohne strenge Kontrollen Egoismus und Dummheit die Oberhand gewinnen und bald jede Nation zerstören, die diese Wahnvorstellungenumarmt. Darüber hinaus reduziert der Affengeist die Zukunft steil, und so arbeiten wir beim Verkauf des Erbes unseres Nachkommen für temporären Komfort zusammen, was die Probleme erheblich verschärft.

The main aim of this dissertation is to model the different ways in which we use language when we engage with fiction. This main aim subdivides itself into a number of puzzles. We all know that dragons do not exist. Yet, when I read the Harry Potter novels, I do accept the existence of dragons. How do we keep such fictional truths separate from ‘ordinary’ non-fictional truths? What is the difference between Tolkien writing down all sorts of falsities, and a (...) liar who also says all sorts of untrue things? How can it be true that Frodo was born in the Shire while it is also true that he was invented by Tolkien? Given that a fiction such as Pride and Prejudice is not about the actual world, how can I learn things about 19th century etiquette in England by reading this novel? -/- I develop a coherent semantic analysis of these different puzzles: the ‘workspace account’. This theory is an extension of Stalnaker’s famous pragmatic ‘common ground’ framework. In this framework, assertions are modelled as proposals to update the ‘common ground’ (the set of shared assumptions) between conversational interlocutors. (shrink)
