Coder’s argument is very similar to Lewis’ one: he maintains that some human beings are not able to follow Gödel’s theorem, so Lucas’ argument cannot show that their minds are not machines. The answer of Lucas is that one proposed against Lewis’ criticism, that is that Mechanism makes a universal claim and so a single counter-example – a single mind producing a singe truth not recognizable by any machine – is a disproof for it.

David Lewis criticizes an argument I put forward against mechansim on the grounds that I fail to distinguish between OL, Lucas's ordinary potential arithmetic output, and OML, Lucas's arithmetical output when accused of being some particular machine M; and correspondingly, between OM the ordinary potential arithmetic output of the machine M, and ONM, the arithmetic output of the machine M when accused of being a particular machine N. For any given machine, M, N, O, P, Q, R,... etc., I can (...) in principle calculate a Godel sentence for that machine - indeed infinitely many, depending on the Godel numbering scheme adopted. The Godel sentence of a particular machine can, I claim, be seen to be true, if that machine is adequate for Elementary Peano Arithmetic. Hence, if I were accused of being M, I can on that supposition see that the Godel sentence of M is true, since I am capable of Elementary Peano Arithmetic and the machine M is said to be an adequate characterization of me.

Le nihilisme a creusé le vide qui est en nous car l'homme est un être risqué et toujours projeté en avant de lui-même. Nous avons laissé le nihilisme s'emparer de ce vide et l'habiter. Nous avons laissé grandir la force mauvaise du nihilisme. Car le nihilisme est une force. Mais c'est une force qui ronge l'homme et détruit le désir du bien et de la vie. Le nihilisme est une force qui nous met en état d'apesanteur et d'oubli de soi. (...) Le nihilisme nous met hors sol par haine de la terre. Il nous met aussi hors de la durée par haine de l'histoire, et des permanences, et des fidélités. Achever le nihilisme, c'est en pousser la logique jusqu'à ce qu'il se détruise lui-même plutôt qu'il ne nous détruise."--Page 4 of cover. (shrink)

Prosper Lucas (1808–1885) is a unique figure in the history of psychiatric genetics. A physician-alienist, he authored one of the most important books on human genetics in the mid-19th century cited frequently by Darwin: the 1,500 page treatise—Philosophical and Physiological Treatise on Natural Heredity (1847–1850). This book contained a novel theory of the nature of inheritance and a detailed review of the heredity of a range of human traits and disorders, including various forms of insanity. Lucas postulated four forms of (...) heredity (direct, crossed, indirect, and atavistic), supported the importance of hereditary factors in insanity, accepted the inheritance of acquired characteristics, considered it important to examine both ancestors and collateral relatives, and recognized that heredity could influence both primary insanity and insanity secondary to other medical conditions. He reviewed the then available literature on most major forms of insanity including separate sections on hallucinations and suicidal monomania. The literature consisted of case reports of unusual families with high concentrations of illness. Lucas advocated for the homogeneity of transmission of forms of illness in families but recognized that—just as the form of illness could evolve within individuals over time—it could change forms when transmitted between relatives.

“Towards a Theory of Taxation” is a proper theme for an Englishman to take when giving a paper in America. After all it was from the absence of such a theory that the United States derived its existence. The Colonists felt strongly that there should be no taxation without representation, and George III was unable to explain to them convincingly why they should contribute to the cost of their defense. Since that time, understanding has not advanced much. In Britain we (...) still maintain the fiction that taxes are a voluntary gift to the Crown, and taxing statutes are given the Royal Assent with the special formula, “La Reine remercie ses bons sujets, accepte leur benevolence, et ainsi le veult” instead of the simple “La Reine le veult,” and in the United States taxes have regularly been levied on residents of the District of Columbia who until recently had no representation in Congress, and by the State of New York on those who worked but did not reside in the State, and so did not have a vote. Taxes are regularly levied, in America as elsewhere, on those who have no say on whether they should be levied or how they should be spent. I am taxed by the Federal Government on my American earnings and by state governments on my American spending, but I should be hard put to it to make out that it was unjust. Florida is wondering whether to follow California in taxing multinational corporations on their world-wide earnings. (shrink)

This edited volume systematically addresses the connection between Wilfrid Sellars and the history of modern philosophy, exploring both the content and method of this relationship. It intends both to analyze Sellars’s position in relation to singular thinkers of the modern tradition, and to inquire into Sellars’s understanding of philosophy as a field in reflective and constructive conversation with its past. The chapters in Part I cover Sellars’s interpretation and use of Descartes, Leibniz, Hume, Kant and Hegel. Part II features essays (...) on his relationship with Peirce, Frege, Carnap, Wittgenstein, American pragmatism, behaviorism and American realism, particularly his father, Roy Wood. Sellars and the History of Modern Philosophy features original contributions by many of the most renowned Sellars scholars throughout the world. It offers an exhaustive survey of Sellars’s views on the historical antecedents and metaphilosophical aspects of his thought. (shrink)

Sets are central to mathematics and its foundations, but what are they? In this book Luca Incurvati provides a detailed examination of all the major conceptions of set and discusses their virtues and shortcomings, as well as introducing the fundamentals of the alternative set theories with which these conceptions are associated. He shows that the conceptual landscape includes not only the naïve and iterative conceptions but also the limitation of size conception, the definite conception, the stratified conception and the (...) graph conception. In addition, he presents a novel, minimalist account of the iterative conception which does not require the existence of a relation of metaphysical dependence between a set and its members. His book will be of interest to researchers and advanced students in logic and the philosophy of mathematics. (shrink)

J. R. Lucas argues in “Minds, Machines, and Gödel”, that his potential output of truths of arithmetic cannot be duplicated by any Turing machine, and a fortiori cannot be duplicated by any machine. Given any Turing machine that generates a sequence of truths of arithmetic, Lucas can produce as true some sentence of arithmetic that the machine will never generate. Therefore Lucas is no machine.

J. R. Lucas serves warning that he stands ready to refute any sufficiently specific accusation that he is a machine. let any mechanist say, to his face, that he is some particular machine M; Lucas will respond by producing forthwith a suitable Gödel sentence ϕM. Having produced ϕM, he will then argue that — given certain credible premises about himself — he could not have done so if the accusation that he was M had been true. let the mechanist try (...) again; Lucas will counter him again in the same way. It is not possible to accuse Lucas truly of being a machine. (shrink)

This book uses mathematical models of language to explain why there are certain gaps in language: things that we might expect to be able to say but can't. For instance, why can we say I ran for five minutes but not *I ran to the store for five minutes? Why is five pounds of books acceptable, but *five pounds of book not acceptable? What prevents us from saying *sixty degrees of water to express the temperature of the water in a (...) swimming pool when sixty inches of water can express its depth? And why can we not say *all the ants in my kitchen are numerous? The constraints on these constructions involve concepts that are generally studied separately: aspect, plural and mass reference, measurement, and distributivity. In this book, Lucas Champollion provides a unified perspective on these domains, connects them formally within the framework of algebraic semantics and mereology, and uses this connection to transfer insights across unrelated bodies of literature and formulate a single constraint that explains each of the judgments above.

Transmission of justification across inference is a valuable and indeed ubiquitous epistemic phenomenon in everyday life and science. It is thanks to the phenomenon of epistemic transmission that inferential reasoning is a means for substantiating predictions of future events and, more generally, for expanding the sphere of our justified beliefs or reinforcing the justification of beliefs that we already entertain. However, transmission of justification is not without exceptions. As a few epistemologists have come to realise, more or less trivial forms (...) of circularity can prevent justification from transmitting from p to q even if one has justification for p and one is aware of the inferential link from p to q. In interesting cases this happens because one can acquire justification for p only if one has independent justification for q. In this case the justification for q cannot depend on the justification for p and the inferential link from p to q, as genuine transmission would require. The phenomenon of transmission failure seems to shed light on philosophical puzzles, such as Moore's proof of a material world and McKinsey's paradox, and it plays a central role in various philosophical debates. For this reason it is being granted continued and increasing attention. (shrink)

In this paper I examine the genesis of Kant’s conception of a realm of ends, arguing that Kant first started to think of morality in terms of striving to be a member of a realm of ends, understood as an ideal community, in the early 1760s, and that he was influenced in this by his encounter with the Swedish mystic Emanuel Swedenborg. In 1766 Kant published Dreams of a Spirit Seer, a commentary on Swedenborg’s magnum opus, Heavenly Secrets. Most commentators (...) take Kant’s attitude towards Swedenborg to have been entirely negative, and argue that, at the most, Kant’s encounter with him had a purely negative impact on Kant’s development, inducing him to reject certain of his early metaphysical positions. I argue, in contrast, that Swedenborg had a positive influence on Kant’s development, particularly on his ethics, for Kant’s conception of a realm of ends is modeled on Swedenborg’s conception of heaven as a community of spirits governed by moral laws.

Public participation in scientific research has gained prominence in many scientific fields, but the theory of participatory research is still limited. In this paper, we suggest that the divergence of values and goals between academic researchers and public participants in research is key to analyzing the different forms this research takes. We examine two existing characterizations of participatory research: one in terms of public participants' role in the research, the other in terms of the virtues of the research. In our (...) view, each of these captures an important feature of participatory research but is, on its own, limited in what features it takes into account. We introduce an expanded conception of norms of collaboration that extends to both academic researchers and public participants. We suggest that satisfying these norms requires consideration of the two groups' possibly divergent values and goals, and that a broad characterization of participatory research that starts from participants' values and goals can motivate both public participants’ role in the research and the virtues of the research. The resulting framework clarifies the similarities and differences among participatory projects and can help guide the responsible design of such projects. (shrink)

‘Futility’ is a contentious term that has eluded clear definition, with proposed descriptions either too strict or too vague to encompass the many facets of medical care. Requests for futile care are often surrogates for requests of a more existential character, covering the whole range of personal, emotional, cultural and spiritual needs. Physicians and other practitioners can use requests for futile care as a valuable opportunity to connect with their patients at a deeper level than the mere biomedical diagnosis. Current (...) debate around Canada’s changing regulatory and legal framework highlights challenges in appropriately balancing the benefits and burdens created by requests for futile care. (shrink)

Crispin Wright has given an explanation of how a first time warrant can fall short of transmitting across a known entailment. Formal epistemologists have struggled to turn Wright’s informal explanation into cogent Bayesian reasoning. In this paper, I analyse two Bayesian models of Wright’s account respectively proposed by Samir Okasha and Jake Chandler. I argue that both formalizations are unsatisfactory for different reasons, and I lay down a third Bayesian model that appears to me to capture the valid kernel of (...) Wright’s explanation. After this, I consider a recent development in Wright’s account of transmission failure. Wright suggests that his condition sufficient for transmission failure of first time warrant also suffices for transmission failure of supplementary warrant. I propose an interpretation of Wright’s suggestion that shield it from objections. I then lay down a fourth Bayesian framework that provides a simplified model of the unified explanation of transmission failure envisaged by Wright. (shrink)

The notions of common knowledge or common belief play an important role in several areas of computer science , in philosophy, game theory, artificial intelligence, psychology and many other fields which deal with the interaction within a group of “agents”, agreement or coordinated actions. In the following we will present several deductive systems for common knowledge above epistemic logics –such as K, T, S4 and S5 –with a fixed number of agents. We focus on structural and proof-theoretic properties of these (...) calculi. (shrink)

Recent works in epistemology show that the claim that coherence is truth conducive – in the sense that, given suitable ceteris paribus conditions, more coherent sets of statements are always more probable – is dubious and possibly false. From this, it does not follows that coherence is a useless notion in epistemology and philosophy of science. Dietrich and Moretti (Philosophy of science 72(3): 403–424, 2005) have proposed a formal of account of how coherence is confirmation conducive—that is, of how the (...) coherence of a set of statements facilitates the confirmation of such statements. This account is grounded in two confirmation transmission properties that are satisfied by some of the measures of coherence recently proposed in the literature. These properties explicate everyday and scientific uses of coherence. In his paper, I review the main findings of Dietrich and Moretti (2005) and define two evidence-gathering properties that are satisfied by the same measures of coherence and constitute further ways in which coherence is confirmation conducive. At least one of these properties vindicates important applications of the notion of coherence in everyday life and in science. (shrink)

According to Jim Pryor’s dogmatism, if you have an experience as if P, you acquire immediate prima facie justification for believing P. Pryor contends that dogmatism validates Moore’s infamous proof of a material world. Against Pryor, I argue that if dogmatism is true, Moore’s proof turns out to be non-transmissive of justification according to one of the senses of non-transmissivity defined by Crispin Wright. This type of non-transmissivity doesn’t deprive dogmatism of its apparent antisceptical bite.

The focus of the following comments will be mainly on Mugnai's characterization of Leibniz's ‘mild nominalism’. Mugnai seems to suggest that Leibniz might have had in mind an ontological commitment view. My idea is that such a construal can be somewhat misleading, for Leibniz's ontological cautiousness seems to stem, in an utter Ockhamistic spirit, from more general considerations about theory building and theory choice.

We present an inferentialist account of the epistemic modal operator might. Our starting point is the bilateralist programme. A bilateralist explains the operator not in terms of the speech act of rejection ; we explain the operator might in terms of weak assertion, a speech act whose existence we argue for on the basis of linguistic evidence. We show that our account of might provides a solution to certain well-known puzzles about the semantics of modal vocabulary whilst retaining classical logic. (...) This demonstrates that an inferentialist approach to meaning can be successfully extended beyond the core logical constants. (shrink)

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

Proclus, head of the Philosophy School at Athens for fifty years, was one of the leading philosophical figures in Late Antiquity. Lucas Siorvanes here introduces Proclus to English-language readers, discussing his metaphysics and theory of knowledge and focusing in particular on his Neo-Platonism. Proclus lived in the turbulent fifth century A.D., a time of struggles among Christians, Jews, and pagans, the invasion of Attila the Hun, the fall of the Western Roman Empire, and the rise of the Eastern Roman Empire (...) in Byzantium. While Late Antiquity has been regarded as a time of superstition and forbiddingly complex philosophies, recent scholarship has shown it to be full of cultural and intellectual vigor. During Proclus's tenure as head of the Philosophy School, he systematized Neo-Platonism as the summit of ancient Greek thought, brought it to its peak of influence, and became responsible for the form in which it was transmitted to the Byzantine, Western European, and Islamic civilizations. Siorvanes's extensive original research presents Proclus as much more than just a metaphysician. He surveys all of Proclus's philosophical interests—including religion, physics, astronomy, mathematics, and poetry—revealing the philosopher's central concern with the problems of being and knowledge and relating the ideas of Proclus to those of such other major thinkers as Plato, Aristotle, and Ptolemy. To help the newcomer, Siorvanes supplies more than 200 quotations from Proclus's works. He also traces the impact of Proclus's Neo-Platonism across cultures, religions, and centuries, in such diverse areas as Christian and Islamic theologies, Renaissance art, Kepler's astronomy, Romantic poetry, Emerson's thought, modern philosophy and science, and current popular phrases.

ABSTRACTLinguistic evidence supports the claim that certain, weak rejections are less specific than assertions. On the basis of this evidence, it has been argued that rejected sentences cannot be premisses and conclusions in inferences. We give examples of inferences with weakly rejected sentences as premisses and conclusions. We then propose a logic of weak rejection which accounts for the relevant phenomena and is motivated by principles of coherence in dialogue. We give a semantics for which this logic is sound and (...) complete, show that it axiomatizes the modal logic KD45 and prove that it still derives classical logic on its asserted fragment. Finally, we defend previous logics of strong rejection as being about the linguistically preferred interpretations of weak rejections. (shrink)

In this paper I discuss a new kind of hinge epistemology which is called transcendental hinge epistemology. According to this view, hinges are immune from doubt because it is impossible to doubt them coherently, and this impossibility arises because any attempt to doubt them will presuppose their truth. Such an immunity is possessed only by inescapable hinges, that is, hinges that must be presupposed in every inquiry. I will argue that current hinge epistemologies fail to provide a satisfactory anti-sceptical strategy (...) because they focus on escapable hinges, that is, hinges with respect to which one can entertain coherent doubts.

The Lucas critique has been – and continues to be – the cornerstone of modern macroeconomic modelling. In this note we apply the Lucas critique to macroeconomic modelling using deep rational expectations. In conclusion, we point out that Lucas's critique reveals a fundamental flaw in Lucas's own, popular 'solution', i.e., the so-called forward-looking rational expectations models. Heeding Lucas's call for model-consistent policy advice eventually requires an ontological shift in economics – which throws the door wide open to an exciting, hardly-explored (...) field of economic research.
