This work-in-progress paper consists of four points which relate to the foundations and physical realization of quantum computing. The first point is that the qubit cannot be taken as the basic unit for quantum computing, because not every superposition of bit-strings of length n can be factored into a string of n-qubits. The second point is that the “No-cloning” theorem does not apply to the copying of one quantum register into another register, because the mathematical representation of this copying is (...) the identity operator, which is manifestly linear. The third point is that quantum parallelism is not destroyed only by environmental decoherence. There are two other forms of decoherence, which we call measurement decoherence and internal decoherence, that can also destroy quantum parallelism. The fourth point is that processing the contents of a quantum register “one qubit at a time” destroys entanglement. (shrink)

Passive frame theory attempts to illuminate what consciousness is, in mechanistic and functional terms; it does not address the “implementation” level of analysis (how neurons instantiate conscious states), an enigma for various disciplines. However, in response to the commentaries, we discuss how our framework provides clues regarding this enigma. In the framework, consciousness is passive albeit essential. Without consciousness, there would not be adaptive skeletomotor action.

Epistemic two-dimensional semantics (E2D), advocated by Chalmers (2006) and Jackson (1998), among others, aims to restore the link between necessity and a priority seemingly broken by Kripke (1972/1980), by showing how armchair access to semantic intensions provides a basis for knowledge of necessary a posteriori truths (among other modal claims). The most compelling objections to E2D are that, for one or other reason, the requisite intensions are not accessible from the armchair (see, e.g., Wilson 1982, Melnyk 2008). As we substantiate (...) here, existing versions of E2D are indeed subject to such access-based objections. But, we moreover argue, the difficulty lies not with E2D but with the typically presupposed conceiving-based epistemology of intensions. Freed from that epistemology, and given the right alternative---one where inference to the best explanation (i.e., abduction) provides the operative guide to intensions---E2D can meet access-based objections, and fulfill its promise of restoring the desirable link between necessity and a priority. This result serves as a central application of Biggs and Wilson 2016 (summarized here), according to which abduction is an a priori mode of inference. (shrink)

Kalam cosmological arguments have recently been the subject of criticisms, at least inter alia, by physicists---Paul Davies, Stephen Hawking---and philosophers of science---Adolf Grunbaum. In a series of recent articles, William Craig has attempted to show that these criticisms are “superficial, iII-conceived, and based on misunderstanding.” I argue that, while some of the discussion of Davies and Hawking is not philosophically sophisticated, the points raised by Davies, Hawking and Grunbaum do suffice to undermine the dialectical efficacy of kalam cosmological arguments.

According to Stephen Finlay, ‘A ought to X’ means that X-ing is more conducive to contextually salient ends than relevant alternatives. This in turn is analysed in terms of probability. I show why this theory of ‘ought’ is hard to square with a theory of a reason’s weight which could explain why ‘A ought to X’ logically entails that the balance of reasons favours that A X-es. I develop two theories of weight to illustrate my point. I first look (...) at the prospects of a theory of weight based on expected utility theory. I then suggest a simpler theory. Although neither allows that ‘A ought to X’ logically entails that the balance of reasons favours that A X-es, this price may be accepted. For there remains a strong pragmatic relation between these claims. (shrink)

A brief biography of evolutionary biologist Stephen Jay Gould.

In this essay I will attempt to explain the significance of Stephen Bantu Biko's life. This I will do in terms of his intellectual contribution to the liberation of black people from the radically unjust apartheid society in South Africa. Firstly, I will discuss his contribution to liberate blacks psychologically from the political system of apartheid, pointing out how he broke through the normative and pragmatic acceptance of the situation in the radically unjust apartheid society. He experienced black people (...) as being defeated people, and he wanted to direct their attention to the fact that the cause of their unjust situation was other human beings and thus they could change it. Secondly, I point out how he gave black people a new self-understanding and self worth. One way of doing this was by means of community projects which fostered self-reliance. For Biko it was important that black people should act autonomously, and not let other people make decisions on their behalf. They also had to re-evaluate their cultural heritage to discover the positive aspects thereof. Lastly, I focus on his views on his ideal for a future just South Africa and show how important he regarded dialogue as a political tool. (shrink)

There seems to be widespread agreement that there are two modal values: necessity and possibility. X is necessary if it is not possible that not-X; and Y is possible if it is not necessary that not-Y. In their path-breaking book, Rani Lill Anjum and Stephen Mumford defend the radical idea that there is a third modal value, weaker than necessity and stronger than possibility. This third value is dubbed 'dispositional modality' (DM) or 'tendency' and is taken to be an (...) irreducible and sui generis worldly modality: "the modality that's everywhere" (5). The source of DM is the causal powers of particulars; hence, DM is constitutively involved in causation: "a cause tends or disposes towards its effect, and can sometimes succeed in producing it" (9). Accordingly, DM is involved in all causal processes, from fundamental physics to the social and moral realm. This "deeply tendential view" (11) of the metaphysics of nature is advanced as distinct from both extant neo-Aristotelian and Humean views. Its key feature is that there is neither pure contingency nor necessitation in nature. (shrink)

In accordance with the critical women’s health literature recounting the ways that women are encouraged to submit themselves to various sorts of health “imperatives”, I investigate the messages tacitly conveyed to women in “campaigns for the cure” and breast cancer awareness efforts, which, I argue, overemphasizes a “positive attitude”, healthy lifestyle, and cure rather than prevention of this life-threatening disease. I challenge that the message of hope pervading breast cancer discourse silences the despair felt by many women, furthers a tacit (...) blaming for disease infliction via a rhetoric of personal responsibility, underemphasizes other cogent health determinants like environmental toxicity, and undermines legitimate critiques of current biomedical practices like widespread mammography. While finding a cure for breast cancer is a laudable and worthwhile healthcare goal that can understandably be shared by women’s health activists, corporate sponsors, and the medical community, this paper resists the current formation of campaigns for the cure and “pink ribbon activism” in general.

Stephen Finlay’s Confusion of Tongues is a bold and sophisticated book. The overarching goal is metaphysical: to reductively analyze normative facts, properties, and relations in terms of non-normative facts, properties, and relations. But the method is linguistic: to first provide a reductive analysis of the corresponding bits of normative language, with a particular focus on ‘good’, ‘ought’, and ‘reason’. The gap between language and reality is then bridged by taking linguistic analysis as a guide to conceptual analysis, and conceptual (...) analysis as a guide to metaphysical analysis. In this review, I consider three challenges to Finlay’s project that deserve more attention than they receive in the book. The first concerns Finlay’s claim to have provided a *reductive* theory of normative language, the second concerns his claim to have provided a *unified* theory of normative language, and the third concerns his claim to have provided a *correct* theory of normative language.

In the December 2015 Issue of the Police Journal Sam Poyser and Rebecca Milne addressed the subject of miscarriages of justice. Cold case investigations can address some of these wrongs. The salient points for attention are those just before his sudden death: Milligan was appointed Private Secretary to Jonathan Aitken, the then Minister of Arms in the Conservative government in 1994. The known facts are as follows: 1. Stephen David Wyatt Milligan was found deceased on Tuesday 8th February 1994 (...) at his Chiswick, West London house where he lived alone. His body was found by his secretary Vera Taggart who was told by Julie Kirkbride where a spare key to his London house was kept and who decided to go to his house that day because he was not answering his telephone. Police said he had made one last telephone call on Saturday evening at 9.00pm. 2. Stephen David Wyatt Milligan had been the elected Member of Parliament (‘MP’) for Eastleigh in Hampshire since 1992. 3. The important topics this MP was addressing in 1994 at the time of his death included: (i) rail privatization plans and the impact through job losses on communities, especially his own constituency of Eastleigh; (ii) arms dealings with Saudi Arabia, especially with his previous intelligence gathered as an economics journalist for esteemed publications; (iii) the UK military industry; (iv) homosexuality among senior government Ministers, as revealed by British footballer Fasanu; (v) personal relationship and planned marriage to his fiancée (Julie Kirkbride) who at the time was a political journalist. 4. Stephen Milligan was also appointed as Parliamentary Private Secretary to Jonathan Aitken, Arms Minister and this position must have required that he came ‘up to speed’ on international arms trade and indeed its relation to bribery and corruption across jurisdictions. Milligan’s experience and knowledge as a former high-level political and economics journalist must have been of huge benefit to government minister Jonathan Aitken who was later imprisoned for perjury. 5. Regarding Stephen Milligan’s death in 1994, the Guardian newspaper in their immediate obituary said that ‘The death of one of the government's most outspoken and loyal supporters will pose a stiff electoral test for the Tories to surmount. He was on the left of the Tory party - he had even had a brief flirtation with the SDP when it was formed - and was a noted Euro-enthusiast… the death of one of the government's most outspoken and loyal supporters will pose a stiff electoral test for the Tories to surmount. Regarding Stephen Milligan’s sudden and unexpected death in 1994, MP David Willetts (Conservative, Havant) said in March 2015, in his address in the House of Commons. ‘…The inevitable ups and downs and triumphs and disasters of politics are among the great features of this place. There are colleagues in all parts of the House who are tolerant and understanding. There are friendships that keep the downs as well as the ups of politics in perspective. Having entered the House in 1992, I think particularly of two good friends, Judith Chaplin and Stephen Milligan, who both died within two years of being elected; that loss stayed with me for a long time...’ 6. On 28 February 2000, in the House of Commons, at Column 106, Mr Mike Hancock (Portsmouth) said, on the deaths of Michael Colvin and of Stephen Milligan MP: ‘I knew Michael Colvin for nearly 30 years, from when he was first elected to Hampshire county council. During my time as leader of that council, he and the late former Member of Parliament for Eastleigh, Stephen Milligan, were usually the only Members of Parliament who readily supported the council when necessary. Michael Colvin supported many ventures in the county of Hampshire. He will be missed here, in his constituency, and in Europe, and I stress that Hampshire has lost a staunch supporter. I am sure that the county will at some stage want to record its regret at his death and its deepest appreciation of the part that he played in its life....’ -/- Mike Hancock had, like Stephen Milligan, served on the Select Committee on Defence. It is interesting that he mentioned Stephen Milligan’s support as MP for Eastleigh when Milligan had only been so appointed a couple of years before his sudden death, as compared to 30 years of support from Mike Colvin. 7. Mr Andrew Robathan (for Blaby) said in the House of Commons Hansard Debates on 27 January1997, (Column 62) (on the registering of sex offenders): ‘I remember the death of my honourable friend Stephen Milligan, who represented Eastleigh. The press reports of the time stated that each Metropolitan police station had a police officer in the pay of newspapers. I do not know whether that is true, but I am aware that the police are not renowned for being entirely secure with their information…’ This statement is mischievous and it has been demonstrated time and time again, as being untrue, especially during the recent press inquiry leading to the four-volume Leveson Report, published in November 2012, into phone hacking and the ethics and culture of the UK media, pursuant to section 26 of the Inquiries Act 2005, and ordered by the House of Commons to be printed on 29 November 2012, ISBN: 9780102981063, by the Stationery Office Limited on behalf of the Controller of Her Majesty’s Stationery Office. In Volume 4 of the 2012 Leveson Report, chapter 4 concluded on the Press Complaints Commission (‘PCC’) and its effectiveness and revealed that the PCC does not initiate its own investigations other than those ‘needed to head off criticism of the press or self-regulation- or to accept complaints from third parties across the board and on a transparent basis… and the report states that ‘the resources of the police are limited’ in terms of being able to fully inspect the Press and media reports.

In this paper I discuss Stephen Davies’s defence of literalism about emotional descriptions of music. According to literalism, a piece of music literally possesses the expressive properties we attribute to it when we describe it as ‘sad’, ‘happy’, etc. Davies’s literalist strategy exploits the concept of polysemy: the meaning of emotion words in descriptions of expressive music is related to the meaning of those words when used in their primary psychological sense. The relation between the two meanings is identified (...) by Davies in music’s presentation of emotion-characteristics-in-appearance. I will contend that there is a class of polysemous uses of emotion terms in descriptions of music that is not included in Davies’s characterization of the link between emotions in music and emotions as psychological states. I conclude by indicating the consequences of my claim for the phenomenology of expressive music. (shrink)

Critical examination of the concept of property in the body, with particular relevance to Stephen Munzer's work on umbilical cord blood.

In Squaring the Circle in Descartes’ Meditations, Stephen Wagner aims to show that Descartes’ project in the Meditations is best understood as a ‘strong validation of reason’ i.e., as proving in a non-circular way that human reason is a reliable, truth-conducive faculty. For such an enterprise to qualify as a ‘strong’ validation, Wagner contends, skeptical doubt must be given its strongest force. The most stringent doubt available in the Meditations is the deceiving God. To rule out the possibility that (...) an omnipotent God created humans so that their best functioning cognitive faculties provide misleading information about what the world is like, Descartes must prove that a non-deceiving God exists. Furthermore, only a non-circular proof will count as a ‘validation.’ Wagner spells out the requirements of non-circularity as involving a proof for God’s existence that is not deductive, does not simply achieve a clear and distinct perception of God’s existence, and proceeds on the basis of perceptions that remain true even when the reasons underlying them are not attended to any longer by the meditator.

This is a response to Stephen Maitzen’s paper. ‘Moral Conclusions from Nonmoral Premises’. Maitzen thinks that No-Ought-From-Is is false. He does not dispute the formal proofs of Schurz and myself, but he thinks they are beside the point. For what the proponents of No-Ought-From-Is need to show is not that you cannot get SUBSTANTIVELY moral conclusions from FORMALLY non-moral premises but that you cannot get SUBSTANTIVELY moral conclusions from SUBSTANTIVELY non-moral premises. And he believes that he can derive substantively (...) moral conclusions from FORMALLY moral but SUBSTANTIVELY nonmoral premises. However his argument relies on what I call ‘taxonomic essentialism’, the thesis that sentences do not change their semantic characters from context to context or from world to world. In particular, they do not change their META-ETHICAL status from context to context or world to world. If a sentence is non-moral at one world it is non-moral at all the rest. This thesis leads to contradictions (with some propositions as both moral and non-moral) and even if (as is perhaps possible) these contradictions can be avoided, it leads to further consequences that are palpably absurd. Thus It may be possible to derive substantively moral conclusions from premises that are not substantively moral, but if it is, Maitzen has failed to prove the point. (shrink)

Resenha de MUMFORD, Stephen. Metaphysics: a very short introduction. Oxford: Oxford University Press, 2012. Principios, v. 21, p. 319-326, 2015.

© Mind Association 2017This rich and engaging book addresses a nest of questions that have been mostly neglected in recent Anglophone philosophy. These questions concern ordinary uses of the concept of identity in speaking for example of identity crises, of one’s identity as something that can be lost or maintained, of identification with certain groups, traits, values, or beliefs, and so on. That there are these uses, and that they are an important feature of contemporary culture, is beyond question: witness (...) the difficulty in helping undergraduates focus in the classroom on what ‘we’ mean by personal identity, where this meaning is supposed to be distinct from the substantive use of ‘identity’ to mean something that a person has, and that can change or be replaced over the course of their continued life....

Review of Glimpse of Light. New Meditations on First Philosophy by Stephen Mumford.

In 'Aboutness' (MIT Press 2014), Yablo argues for the importance of the notions of partial content and partial truth. This paper argues that they are involved in a much greater range of entities than acknowledged by Yablo. The paper also argues that some of those entities involve a notion of partial satisfaction as well as partial existence (validity).

In this book, Mumford and Anjum advance a theory of causation based on a metaphysics of powers. The book is for the most part lucidly written, and contains some interesting contributions: in particular on the necessary connection between cause and effect and on the perceivability of the causal relation. I do, however, have reservations about some of the book’s central theses: in particular, that cause and effect are simultaneous, and that causes can fruitfully be represented as vectors.

A review of Finlay's Confusion of Tongues.

The continuing interest in the book of S. Hawking "A Brief History of Time" makes a philosophical evaluation of the content highly desirable. As will be shown, the genre of this work can be identified as a speciality in philosophy, namely the proof of the existence of God. In this study an attempt is given to unveil the philosophical concepts and steps that lead to the final conclusions, without discussing in detail the remarkable review of modern physical theories. In the (...) first place the concept of causality used by Hawking is analyzed in terms of the classical four aspects of cause, that is causa formalis, materialis, efficiens and finalis. Thereafter the classical Aristotelian-Thomistic proof of the existence of God is presented and compared with Hawking's approach. In his argumentation he uses a concept of causality, which in contrast to the classical philosophy neglects completely an ontological dependence and is reduced to only temporal aspects. On the basis of this temporal causality and modern physical theories and speculations, Hawking arrives at his conclusions about a very restricted role of a possible creator. It is shown, that neither from the philosophical nor the scientific view his conclusions about the existence of God are strictly convincing, a position Hawking himself seems to be aware of. (shrink)

In his book The Things We Mean, Stephen Schiffer advances a subtle defence of what he calls the ‘face-value’ analysis of attributions of belief and reports of speech. Under this analysis, ‘Harold believes that there is life on Venus’ expresses a relation between Harold and a certain abstract object, the proposition that there is life on Venus. The present essay first proposes an improvement to Schiffer’s ‘pleonastic’ theory of propositions. It then challenges the face-value analysis. There will be such (...) things as propositions only if they possess conditions of identity and distinctness. By analyzing Frege’s theory of propositions (Gedanken), I argue that such conditions may be found for the special case of beliefs and sayings advanced as premises and conclusions of deductive arguments. These conditions, however, are not applicable to most ordinary beliefs and sayings. Ordinary attributions and reports, then, do not place thinkers and speakers in relations to propositions. A bonus is exposure of the fallacy in the Putnam-Taschek objection to Frege’s theory of sense and reference. (shrink)

In his article ‘Divine hiddenness and the demographics of theism’ (Religious Studies, 42 (2006), 177–191) Stephen Maitzen develops a novel version of the atheistic argument from divine hiddenness according to which the lopsided distribution of theistic belief throughout the world’s populations is much more to be expected given naturalism than given theism. I try to meet Maitzen’s challenge by developing a theistic explanation for this lopsidedness. The explanation I offer appeals to various goods that are intimately connected with the (...) human cognitive constitution, and in particular, with the way in which we depend upon social belief-forming practices for our acquisition of much of our knowledge about the world — features about us that God would value but that also make probable a lopsided distribution of theistic belief, or so I argue.

This paper aims to cast doubt upon a certain way of analysing prudential value (or good for ), namely in the manner of a ‘buck-passing’ analysis. It begins by explaining why we should be interested in analyses of good for and the nature of buck-passing analyses generally (§I). It moves on to considering and rejecting two sets of buck-passing analyses. The first are analyses that are likely to be suggested by those attracted to the idea of analysing good for in (...) a buck-passing fashion (§II). The second are the buck-passing analyses of good for proposed by John Skorupski (§III), Henry Sidgwick (§IV), and Stephen Darwall (§V). Along the way the paper shows that Michael Smith’s and Peter Railton’s analyses of other concepts—analyses that could be (and have been) taken to be analyses of good for —are similarly unsuitable as analyses of it. The paper concludes by suggesting that the fact that none of the buck-passing accounts of good for considered here is satisfactory, coupled with an appreciation of the various problems that a buck-passing analysis of good for would have to avoid, suggests that we should be sceptical about the prospects of finding such an analysis and should look for one of a different type.

Naturalism in theoretical philosophy comes in three kinds: metaphysical, scientific and semantical. Metaphysical naturalism holds that only natural things exist, scientific (or methodological) naturalism holds that the methods of natural science provide the only avenue to truth, semantic (or analytic) naturalism tries to provide sufficient nonintentional conditions for intentional phenomena. The paper argues that analytic naturalism does not render metaphysical or scientific naturalism obsolete, but can be understood as a further step in elaborating upon these programmes. The intentional idiom of (...) belief-desire psychology is the main obstacle for a scientific view of the world. It is hard to see how human beings and their abilities could get integrated into the natural order if intentional phenomena defy analysis in naturalistically acceptable terms. Against this view, Stephen Stich has argued that the search for a naturalistic criterion of acceptable predicates is misguided, since there is no way of identifying naturalistically acceptable predicates in advance. All that counts, Stich claims, is that the predicates in question are applied in “successful scientific theories”. A naturalist, however, must be able to indicate what he takes to be successful science and why. Perhaps analytic naturalism is without prospect of success. This would be bad news for the naturalist, which he cannot sidestep by claiming hat scientific naturalism must have had something different in mind. (shrink)

I believe that normative force depends on desire. This view faces serious difficulties, however, and has yet to be vindicated. This paper sketches an Argument from Voluntary Response, attempting to establish this dependence of normativity on desire by appeal to the autonomous character of our experience of normative authority, and the voluntary character of our responses to it. I first offer an account of desiring as mentally aiming intrinsically at some end. I then argue that behaviour is only voluntary if (...) it results from such aiming; hence all voluntary behaviour is produced by desire. Full-blooded responses to normativity, I then argue, are voluntary actions: motivation to act arises voluntarily from perception of reasons to act. This fits the desire-based model of normativity but not its rivals. However this argument concludes merely that our responses to normativity are desire-based. I end with some observations about how I think we can bridge the gap from the nature of response to normativity to the nature of normativity itself. (shrink)

Stephen Barker presents a novel approach to solving semantic paradoxes, including the Liar and its variants and Curry’s paradox. His approach is based around the concept of alethic undecidability. His approach, if successful, renders futile all attempts to assign semantic properties to the paradoxical sentences, whilst leaving classical logic fully intact. And, according to Barker, even the T-scheme remains valid, for validity is not undermined by undecidable instances. Barker’s approach is innovative and worthy of further consideration, particularly by those (...) of us who aim to find a solution without logical revisionism. As it stands, however, the approach is unsuccessful, as I shall demonstrate below. (shrink)

A standard example of a justified aggressor is the tactical bomber who is about to destroy an ammunitions factory in a proportionate, justified military attack, full well knowing that an innocent civilian bystander will also be killed by his attack (“collateral damage”). Intuitively it seems hard to believe that the innocent bystander threatened by the tactical bomber is morally prohibited from killing him in self-defense. Yet, Stephen R. Shalom indeed endorses such a prohibition. I shall argue that all the (...) examples Shalom offers in support of his view are disanalogous to the case in question, and provide examples that are analogous and strongly suggest that Shalom’s claim leads to counter-intuitive implications. Moreover, I will provide a clear-cut case that demonstrates that Shalom cannot rely on a general principle prohibiting lethal violence against permissible violence. Thus, I conclude that Shalom has failed to provide a convincing argument in support of his case. (shrink)

The ecologist today finds scarce ground safe from controversy. Decisions must be made about what combination of data, goals, methods, and theories offers them the foundations and tools they need to construct and defend their research. When push comes to shove, ecologists often turn to philosophy to justify why it is their approach that is scientific. Karl Popper’s image of science as bold conjectures and heroic refutations is routinely enlisted to justify testing hypotheses over merely confirming them. One of the (...) most controversial theories in contemporary science is the Neutral Theory of Ecology. Its chief developer and proponent, Stephen Hubbell, presents the neutral theory as a bold conjecture that has so far escaped refutation. Critics of the neutral theory claim that it already stands refuted, despite what the dogmatic neutralists say. We see the controversy through a Popperian lens. But Popper’s is an impoverished philosophy of science that distorts contemporary ecology. -/- The controversy surrounding the neutral theory actually rests on a methodological fault. There is a strong but messy historical link between the concepts of being neutral and being null in biology, and Hubbell perpetuates this when he claims that the neutral theory is supplies the appropriate null for testing alternative theories. What method is being followed here? There are three contenders: -/- Null hypothesis testing tests for whether a there is a pattern to be explained. Null modeling tests for whether a process is causally relevant to a pattern. Baseline modeling apportions relative responsibility to multiple processes each relevant to a pattern. -/- Whether the neutral theory supplies an appropriate “null” depends upon whether null hypothesis, null modeling, or baseline model is intended. These methods prescribe distinct inference patterns. If they are null hypothesis testing or null modeling, the neutralists’s reasoning is invalid. If they are baseline modeling, the justification of a crucial assumption remains opaque. Either way, the neutral-null connection is being exploited rhetorically to privilege the neutral theory over its rivals. Clarifying the reasoning immunizes us against the rhetoric and foregrounds the underlying virtues of the neutralist approach to ecology. -/- The Popperian lens distorts theoretical development as dogmatism. Lakatos’s view of science as the development of research programmes clarifies the epistemology of the neutral theory. Focusing philosophical attention on the neutralist research programme illuminates (1) the synchronic uses of the neutral theory to make predictions and give descriptions and explanations; (2) its diachronic development in response to theoretical innovation and confrontation with data; (3) its complex relationships to alternative theories. For example, baseline modeling is now seen to be its primary explanatory heuristic. The justification for baseline modeling with the neutral theory, previously hidden from view, is seen in the logic of in the neutralist research programme. (shrink)

Stephen Finlay analyses ‘ought’ in terms of probability. According to him, normative ‘ought's are statements about the likelihood that an act will realize some (contextually supplied) end. I raise a problem for this theory. It concerns the relation between ‘ought’ and the balance of reasons. ‘A ought to Φ’ seems to entail that the balance of reasons favours that A Φ-es, and vice versa. Given Finlay's semantics for ‘ought’, it also makes sense to think of reasons and their weight (...) in terms of probability. In this paper, I develop such a theory of weight. It turns out, however, that it cannot explain the entailments. This leaves Finlay with a challenge: to explain these entailments in some other way consistent with his theory, or to show why the appearances deceive and there are no such entailments. (shrink)
