This article argues that common intuitions regarding (a) the specialness of ‘use-novel’ data for confirmation and (b) that this specialness implies the ‘no-double-counting rule’, which says that data used in ‘constructing’ (calibrating) a model cannot also play a role in confirming the model’s predictions, are too crude. The intuitions in question are pertinent in all the sciences, but we appeal to a climate science case study to illustrate what is at stake. Our strategy is to analyse the intuitive (...) claims in light of prominent accounts of confirmation of model predictions. We show that on the Bayesian account of confirmation, and also on the standard classical hypothesis-testing account, claims (a) and (b) are not generally true; but for some select cases, it is possible to distinguish data used for calibration from use-novel data, where only the latter confirm. The more specialized classical model-selection methods, on the other hand, uphold a nuanced version of claim (a), but this comes apart from (b), which must be rejected in favour of a more refined account of the relationship between calibration and confirmation. Thus, depending on the framework of confirmation, either the scope or the simplicity of the intuitive position must be revised. (shrink)

The Doctrine of Double Effect [DDE] states roughly that it is harder to justify causing or allowing harm as a means to an end than it is to justify conduct that results in harm as a side effect. This chapter argues that a theory of deontological constraints on harming needs something like the DDE in order to avoid the charge that it reflects a narcissistic obsession with the cleanliness of our own hands. Unfortunately, the DDE is often interpreted as (...) maintaining that we must avoid acting with certain intentions, which, this chapter contends, embodies an equally narcissistic obsession with the purity of our own hearts. The chapter argues that the DDE is better interpreted as a denial of the Machiavellian idea that beneficial ends justify harmful means. On this view, the objective fact that our conduct will secure benefits for some individuals at the expense of other individuals weakens the extent to which those benefits count as reasons to engage in that conduct. The chapter argues that this version of the DDE provides a plausible, non-narcissistic foundation for deontological constraints. (shrink)

Given the wide the range of legally available options for end-of-life care in recent decades: from aggressive, even experimental, treatment to active euthanasia, our ethical analysis struggles to keep pace with technology and law. In this essay I show that the principle of double effect (PDE) remains, and will continue to be, a useful tool for ethical analysis of end-of-life care. According to PDE, an agent may ethically perform an act that s/he foresees will have a significant bad effect (...) (e.g., death) in addition to a good effect (e.g., pain relief) only if s/he does not intend the bad effect, the act is not bad for reasons other than its causing the bad effect, and there is a proportionately serious reason to act. Following a brief explanation of PDE and preliminary considerations in favor of counting death as a bad effect, I analyze several end-of-life options in terms of the principle. I begin with those that enjoy significant consensus among proponents of PDE: active euthanasia, “passive euthanasia,” and palliative care. Then I consider the less-straightforward cases of drug provision, refusing food and water, and terminal sedation, arguing that participation in such actions is justifiable via PDE only under very limited conditions.

There are some interesting similarities between Aristotle’s ‘mixed actions’ in Book III of the Nicomachean Ethics and the actions often thought to be justifiable with the Doctrine of Double Effect. Here I analyse these similarities by comparing Aristotle’s examples of mixed actions with standard cases from the literature on double effect such as, amongst others, strategic bombing, the trolley problem, and craniotomy. I find that, despite some common features such as the dilemmatic structure and the inevitability of a (...) bad effect, Aristotle’s mixed actions do not count as cases justifiable through application of the Doctrine of Double Effect because they fail to meet the crucial necessary condition of the Doctrine according to which the bad effect can only be a merely foreseen side-effect and not an intended means.

We argue that concerns about double-counting—using the same evidence both to calibrate or tune climate models and also to confirm or verify that the models are adequate—deserve more careful scrutiny in climate modelling circles. It is widely held that double-counting is bad and that separate data must be used for calibration and confirmation. We show that this is far from obviously true, and that climate scientists may be confusing their targets. Our analysis turns on a Bayesian/relative-likelihood (...) approach to incremental confirmation. According to this approach, double-counting is entirely proper. We go on to discuss plausible difficulties with calibrating climate models, and we distinguish more and less ambitious notions of confirmation. Strong claims of confirmation may not, in many cases, be warranted, but it would be a mistake to regard double-counting as the culprit. 1 Introduction2 Remarks about Models and Adequacy-for-Purpose3 Evidence for Calibration Can Also Yield Comparative Confirmation3.1 Double-counting I3.2 Double-counting II4 Climate Science Examples: Comparative Confirmation in Practice4.1 Confirmation due to better and worse best fits4.2 Confirmation due to more and less plausible forcings values5 Old Evidence6 Doubts about the Relevance of Past Data7 Non-comparative Confirmation and Catch-Alls8 Climate Science Example: Non-comparative Confirmation and Catch-Alls in Practice9 Concluding Remarks.

We articulate a holistic understanding of hope, going beyond the common conceptualization of hope in terms of positive affect and cognition by considering what hope means for the underprivileged. In the recognition that hope is always situated in a particular place, we explore the perspective of the privileged and the underprivileged, clarifying how spatial contexts shape their goals for the future and their agency toward attaining these goals. Where some people experience precarity due to their disability, race, gender, sexuality, and (...) social class, others enjoy enhanced agency due to their privilege. In our analysis, this loss of agency does not mean the underprivileged are hopeless; instead, it suggests that hope can incorporate negative affect and cognition. In our view, a spatial understanding acknowledges the power of hope in discouraging situations, and it points to practical measures through which hope can be cultivated by marginalized communities.

In engineering, as in other scientific fields, researchers seek to confirm their models with real-world data. It is common practice to assess models in terms of the distance between the model outputs and the corresponding experimental observations. An important question that arises is whether the model should then be ‘tuned’, in the sense of estimating the values of free parameters to get a better fit with the data, and furthermore whether the tuned model can be confirmed with the same data (...) used to tune it. This dual use of data is often disparagingly referred to as ‘double-counting’. Here, we analyse these issues, with reference to selected research articles in engineering. Our example studies illustrate more and less controversial practices of model tuning and double-counting, both of which, we argue, can be shown to be legitimate within a Bayesian framework. The question nonetheless remains as to whether the implied scientific assumptions in each case are apt from the engineering point of view. (shrink)

Corroborative evidence can have a dual function in argument whereby not only does it have a primary function of providing direct evidence supporting the main conclusion, but it also has a secondary, bolstering function which increases the probative value of some other piece of evidence in the argument. It has been argued (Redmayne, 2000) that this double function gives rise to the fallacy of double counting whereby the probative weight of evidence is overvalued by counting it (...) twice. Walton has proposed several models of corroborative evidence, each of which seems to accept the fallaciousness of double counting thereby seeming to deny the dual function of corroborative evidence. Against this view, I argue that the bolstering effect is legitimate, and can be explained by recourse to inference to the best explanation. (shrink)

In this chapter, I examine Lewis's ideas about ontological innocence, ontological commitment and double-counting, in his discussion of composition as identity in Parts of Classes. I attempt to understand these primarily as epistemic or methodological claims: how far can we get down this route without adopting radical metaphysical theses about composition as identity?

Some argue that procreation is immoral due to its negative environmental impact. Since living an “eco-gluttonous” lifestyle of excessive resource consumption is wrong in virtue of the fact that it increases greenhouse gas emissions and environmental impact, then bringing another human being into existence must also be wrong, for exactly this same reason. I support this position. It has recently been the subject of criticism, however, primarily on the grounds that such a position (1) is guilty of “double-counting” (...) environmental impacts, and (2) that it over-generalizes to condemn other clearly permissible behaviors, such as saving lives, or certain instances of adoption and immigration. Here, I will defend the environmental argument against procreation from these criticisms. I will do this, first, under the assumption that our individual consumption and emissions cause significant harm. I will then address the problem of causal impotence, and argue that, even if our individual contributions to environmental problems ultimately make no difference to the amount of harm that occurs, procreation is still immoral for many, if not most, of those living in the developed world.

The Subset View of realization, though it has some attractive advantages, also has several problems. In particular, there are five main problems that have emerged in the literature: Double-Counting, The Part/Whole Problem, The “No Addition of Being” Problem, The Problem of Projectibility, and the Problem of Spurious Kinds. Each is reviewed here, along with solutions (or partial solutions) to them. Taking these problems seriously constrains the form that a Subset view can take, and thus limits the kinds of (...) relations that can fulfill the realization relation on this view. (shrink)

An externalist view of intention is developed on broadly Wittgensteinian grounds, and applied to show that the classic Thomist doctrine of double effect, though it has good uses in casuistry, has also been overused because of the internalism about intention that has generally been presupposed by its users. We need a good criterion of what counts as the content of our intentional actions; I argue, again on Wittgensteinian grounds, that the best criterion comes not from foresight, nor from foresight (...) plus some degree of probability, nor from any metaphysics of “closeness”, but simply from our ordinary shared understanding of what counts as doing a given action, and what does not.

_ Source: _Page Count 25 This is a pre-print. Please cite only the revised published version. This paper presents an original, ambitious, truth-directed transcendental argument for the existence of an ‘external world’. It begins with a double-headed starting-point: Stroud’s own remarks on the necessary conditions of language in general, and Hegel’s critique of the “fear of error.” The paper argues that the sceptical challenge requires a particular critical concept of thought as that which may diverge from reality, and that (...) this concept is possible only through reflection on situations of error, in which how things are thought to be diverges from how things really are with independent items in an objective world. The existence of such a world is therefore a necessary condition of the possibility of scepticism: such scepticism is therefore false. I defend the argument against objections from Stroud’s sceptic and others. Drawing on Heidegger, the paper concludes by indicating that the chain of necessary conditions includes practical engagement with the world. (shrink)

I propose a comprehensive account of negation as a modal operator, vindicating a moderate logical pluralism. Negation is taken as a quantifier on worlds, restricted by an accessibility relation encoding the basic concept of compatibility. This latter captures the core meaning of the operator. While some candidate negations are then ruled out as violating plausible constraints on compatibility, different specifications of the notion of world support different logical conducts for negations. The approach unifies in a philosophically motivated picture the following (...) results: nothing can be called a negation properly if it does not satisfy Contraposition and Double Negation Introduction; the pair consisting of two split or Galois negations encodes a distinction without a difference; some paraconsistent negations also fail to count as real negations, but others may; intuitionistic negation qualifies as real negation, and classical Boolean negation does as well, to the extent that constructivist and paraconsistent doubts on it do not turn on the basic concept of compatibility but rather on the interpretation of worlds.

Absences pose a dilemma for theories of causation. Allowing them to be causes seems to make theories too permissive (Lewis, 2000). Banning them from being causes seems to make theories too restrictive (Schaffer, 2000, 2004). An increasingly popular approach to this dilemma is to acknowledge that norms can affect which absences count as causes (e.g., Thomson, 2003; McGrath, 2005; Henne et al., 2017; Willemsen, 2018). In this article, I distinguish between two influential implementations of such ‘abnormality’ approaches and argue that (...) so-called ‘double-prevention mechanisms’ provide counterexamples against both.

New biotechnologies have the potential to both dramatically improve human well-being and dramatically widen inequalities in well-being. This paper addresses a question that lies squarely on the fault line of these two claims: When as a matter of justice are societies obligated to include a new biotechnology in a national healthcare system? This question is approached from the standpoint of a twin aim theory of justice, in which social structures, including nation-states, have double-barreled theoretical objectives with regard to human (...) well-being. The first aim is to achieve a sufficient level of well-being in each of six core dimensions. In the special case of healthcare systems, this aim is focally but not exclusively attentive to achieving health sufficiency as one of the core dimensions. The second aim is to combat the emergence and persistence of densely woven patterns of systematic disadvantage that tend to undermine the achievement of a sufficient level of health and the other core elements of well-being of some persons and groups. Judgments about entitlements to health related resources, including new biotechnologies, are made in light of a threshold notion of health sufficiency. What is enough or sufficient health? The answer that is defended here is that sufficient health is enough health for a decent human life, understood as enough health to live a full life course without preventable, significant functional disability or decrement in health, or treatable pain or suffering. When a state must include a new biotechnology in its national healthcare system is also influenced by ancillary concerns about the connection between health and other core dimensions of well-being. What counts as a significant functional impairment or health decrement is thus explicated, in part, in relation to the theory’s sufficiency aim for the other essential dimensions of well-being, and thus for a decent life, overall. Those elements of health that play a critical role in the experience of sufficient reasoning, affiliation, security, respect and self determination are especially important; any loss of health function or capacity that threatens the individual’s prospects for sufficiency in these other dimensions, including the relational egalitiarian concerns they entail, constitutes a significant functional impairment. Within national borders, individuals are thus entitled to those health-related goods and services that are essential for a sufficiency of each of the dimensions of well-being; with regard to self determination and respect, what is sufficient by way of guaranteed access to specific goods and services is going to depend on the implications of such access for where an individual stands in relation to her co-nationals. The content of any entitlement to health-related goods and services is also necessarily dynamic. What can be done for health and the other core dimensions of well-being as a function of technological innovation and diffusion is in constant flux. The paper concludes by considering the implications of this analysis for the conditions under which states are obligated to include access in their healthcare systems to one biotechnology, deep brain stimulation.

The following are the characteristics of a genus: 1. Those to which the same figure of predication applies are one in genus. (Met. , Δ, 1016b32-35) 2. Things that are one in genus are all one by analogy while things that are one by analogy are not all one in genus. (Met, Δ, 1016b35-1017a3) 3. A genus includes contraries. (Met., Δ, 1018a25-31) 4. All the intermediates are in the same genus as one another and as the things they stand between. (...) (Met., I, 1057a18-30; 1057b31-34) 5. Not every predicate is a genus of what it is predicated on; for this would equate a genus with one of its own species. (PsA., A, 22, 83b7-10) 6. The opposite of the genus should always be the genus of the opposite. (To., Δ, 4, ^125a27-29) 7. A genus divides the object from other things. (To., Z, 3, 140a^24) 8. None of unity and being is a genus. (Met., B, 998b22-27; Met., K, 1059b31-34; PsA., B, 7, 92b12-14) 9. There is no necessity or even no possibility that things that are the same specifically or generically should be numerically the same. (To., H, I, 152b30-) 10. To be called one due to having one genus is in a way similar to be one due to having the same matter. (Met., Δ, 1016a24-28) 11. The substance of a thing involves its genus, and thereby all the higher genera are predicated of the lower. (To., Z, 5, 143a^20- ) 12. Being falls immediately into genera. (Met., Γ, 1004a4-6) A. Characteristics of relations between genera The characteristics of relations between genera, the relations between genera and species excluded, are as follows: 1. Genus is not an element in the composition of things. (Met., I, 1057b20-22) 2. Things resulting from the same division of the same genus are simultaneous by nature. (Cat., 13, 15a3-4) 3. Processes of proof cannot pass from one genus to another. (PsA., A, 23, 84b14-18) 4. It is not necessary for subordinate genera to have different accounts. (To., I, 15, ^107a19-) E.g. when we say a raven is a bird, we also say it is a certain kind of animal. 5. It is necessary for genera that are not subordinate one to the other to have different accounts. (To., I, 15, ^107a27-30) E.g. whenever we call a thing an engine, we do not call it an animal, nor vice versa. 6. If one of the genera is predicated in what it is, all of them, both higher and lower than this one, if predicated at all of the species, will be predicated of it in what it is; so that what has been given as genus is also predicated in what it is. (To., Δ, 2, ^122a10) 7. The same object cannot occur in two genera of which neither contains the other. (To., Z, 139b32-140a2) 8. Those to which the same figure (σχῆμα) of predication applies, are the same in genus. (Met., Δ, 1016b32-35) 9. Attributes that inhere always in each several things can be divided to two groups: those that are wider in extent but not wider than its genus and those wider than its genus. (PsA., B, 13, 96a24-27) 10. The relation between A and B must be extendable in respect of all the genera of A. Thus, if A is double of B, it must also be in excess, the genus of double, to B. Aristotle accepts, however, that this may be objectable in some cases: while knowledge is called knowledge of an object of knowledge, it cannot be called a state and disposition (which is the genus of knowledge) of an object of knowledge. In fact, it is a state and disposition of the soul. (To., Δ, 4, 124b28-34) B. Characteristics of species The following are the characteristics of species: 1. Things are said to be other in species if they are of the same genus but are not subordinate the one to the other. (Met., Δ, 1018a38-b2; Met., I, 1057b35-37) 2. Contraries are other than one another in species. (Met., Δ, 1018b5-7; Met., I, 1058b26-) 3. It is not sufficient for a difference to be the basis of distinguishing species in a genus because it belongs to the genus in virtue of its nature as, e.g., the difference between men and women belongs to animal in virtue of its nature. It must also be a modification peculiar to the genus (οἰκεῖα πάθη τοῦ γένους) in the strongest sense. (Met., I, 1058a29-37) Thus, contraries which are in the formula (ἐν τῷ λόγῳ) make a difference in species, but those which are in the compound material thing do not make one as e.g. being male and female is a difference in matter. (Met., I, 1058a37-b23) 4. Some things are peculiar to the species as distinct from genus: there are attributes peculiar to each distinct species. (PrA., A, 27, 43b27-29) 5. There is no necessity or even no possibility that things that are the same specifically should be the same numerically. (To., H, I, 155b30-) C. Characteristics of relations between genera and species The following are the characteristics of relations between genera and their species: 1. Although species predicated of individuals seem to be principles rather than the genera, it is hard to say, Aristotle asserts, in what sense species are to be taken as principles. (Met., B, 999a14-21) 2. Things that are one in species are all one in genus, while things that are one in genus are not all one in species. (Met., Δ, 1016b35a1) 3. The relation of a species to its genus is like the relation of primary substance to all others: the species is a subject for the genus (ὑπόκειται γὰρ τὸ εἴδος τῷ γένει) and the genera are predicated of the species but the species are not predicated of them. (Cat., 5, 2b17-22) 4. Of the species themselves- those which are not genera- one is no more a substance than another: a certain horse is no more a substance than another horse. (Cat., 5, 2b22-26) 5. Genera are prior to species since they do not reciprocate as to implication of existence (κατὰ τὴν τοῦ εἶναι ἀκολούθησιν). For example, if there is a fish there is an animal, but if there is an animal there is not necessarily a fish. (Cat., 13, 15a4-7) 6. What belongs both to a species and to its genus, it belongs to the species more properly indeed than to the genus. (PrA., A, 27, 43b29-32) 7. A predicate drawn from the genus is never ascribed to the species in a derived form and as its genus. Thus, e.g. coloured cannot be a genus of ‘white’ when we say ‘white is coloured.’ (To., B, I, ^109b1-5) 8. Genera are predicated of their species synonymously because the species take on both the name and the account of their genera. (To., B, I, ^109b3-6) 9. All the attributes that belong to the species belong to the genus as well but there is no necessity that all the attributes that belong to the genus should belong also to the species. (To., B, 4, 111a20-32) 10. Those things of which the genus is predicated must also of necessity have one of its species predicated of them. (To., B, 4, 111a33-) 11. The higher genus should be predicated of the species in what it is. (To., Δ, 2, ^122a6) 12. The species, or any of the things which are under the species, is not predicated of the genus because the genus is the term with the widest range of all. (To., Z, 6, 144a27f.) 13. The same species cannot be in two genera neither of which contains the other. (To., Z, 6, 144b14f.) 14. None of the species of a genus is prior or posterior to other species but they are thought to be simultaneous by nature. (Cat., 13, 14b38-15a1) 15. Daniel W. Graham points that sometimes Aristotle speaks of species as classes (Cat., 5, 2a14-17) and sometimes as properties or a certain character (ποιόν τι) of substances, which is difficult to be distinguished from the category of quality. (Cat., 3b13-22) D. Characteristics of differentia 1. The last differentia will be the substance, the definition and the form of the thing. (Met., Z, 1038a18-28) 2. If we divide according to accidental qualities, there will be as many differentiae as there are processes of division. (Met., Z, 1038a25-28) 3. The differentia divides the object from any of the things contained in the same genus. (To., Z, 3, 140a24-) 4. A. C. Lloyd argues that Aristotle’s logic of classification contains a vicious circle because: ‘For a genus to be predicated unequivocally and essentially of a species the specific differentiae have to be ‘appropriate’; but in order to know whether a proposed differentia is appropriate we have to know whether the genus is predicable essentially of the species thus defined.’ The predication of differentia on primary substance seems to make difficulties in Aristotle’s system, as Terence Irwin points out. It seems to violate the distinction of strong predication and inherence, a distinction between predication of count-nouns and predication of characterizing adjectives. Irwin says that this violation is only apparent because although the differentia-term is an adjective, its gender agrees with the gender of the understood genus-term and not with that of the subject term. ‘Man is biped’ is indeed ‘Man is a biped animal.’ This shows, Irwin asserts, ‘why Aristotle can still mention that strong predication is nominal and inherence is adjectival.’ Differentiae are not, however, secondary substances, as Aristotle himself insists. A differentia does not say what the thing is, as secondary substances do, but only what it is like or what sort it is. (ποιον: To., 122b12-17; 128a20-29; 139a28-31; 142b25-29) Nonetheless, differentiae are not qualities because they are not inherent. Thus, they cannot be regarded in any of the ten categories. Irwin thinks that this anomaly is unnecessary because Aristotle could give good reasons for taking differentiae to be second substances. E. Characteristics of relations between differentia and genera or species 1. It is not possible for the genus to be predicated of the differentia taken apart from the species. (Met., B, 998b23-25; Met., K, 1059b31-33; To., VI, 6, 144a32-b1) 2. It is not possible for the species of the genus to be predicated of the proper differentiae of the genus. (Met., B, 998b24-26) 3. Where the differentia is present, the genus accompanies it, but where the genus is, the differentia is not always present. (Met., Δ, 1014b12-14) 4. The number of species are equal to the number of differentiae. (Met., Z, 1038a15-18) 5. The differentiae of genera which are different and not subordinate one to the other are themselves different in kind. (Cat., 3, 1b16-20; To., I, 15, ^107b19-) 6. There is nothing to prevent genera subordinate one to the other from having the same differentia. (Cat., 3, 1b20-22) 7. Since the higher genera are predicated of the genera below them, all differentiae of the predicated genus will be differentia of the subject also. (Cat., 3, 1b21-24) 8. The definition of the differentia is predicated of that of which the differentia is said. (Cat., 5, 3a25-28) 9. In giving what a thing is it is more fitting to state the genus than the differentia. For example, anyone who says that man is an animal shows what man is better than who describes him as terrestrial. (To., Δ, 6, ^128a24-27) 10. The differentia always signifies a quality of the genus, but the genus does not do this of the differentia. (To., Δ, 6, 128a27-29; To., Z, 6, 144a20-23) 11. A specific differentia, along with the genus, always makes a species. (To., Z, 6, 143b^1-) 12. A genus is always divided by the differentiae that are co-ordinate with it in a division and the differentiae that are co-ordinate in a division are all true of the genus. (To., Z, 6, 143b^1-) 13. Differentia cannot be predicated of the genus because genus is the term with the wider range. (To., Z, 6, 144a27-) In fact, genus is predicated, not of the differentia, but of the object of which the differentia is predicated. (To., Z, 6, 144a^31-b3) 14. Neither species nor the objects under it can be predicated of the differentia because the differentia is a term with a wider range than the species. (To., Z, 6, 144b4-) 15. The differentia is posterior to genus but prior to the species. (To., Z, 6, 144b^9-) 16. The same differentia cannot be used of two genera neither of which contains the other and if they do not both fall under the same genus. Otherwise, the same species will be in two genera neither of which contains the other, which is impossible. (To., Z, 6, 144b14-) 17. Genus and differentia are prior to and more familiar than the species: ‘For annul the genus and the differentia; and the species too is annulled, so that they are prior to the species. They are also more familiar; for if the species is known, the genus and differentia must of necessity be known as well (for anyone who knows what a man is knows also what animal and terrestrial are), whereas if the genus or the differentia is known it does not follow of necessity that the species is known as well; thus the species is less intelligible.’ (To., Z, 4, 141b15-) F. Characteristics of relations in series of classes 1. Mutually exclusive series. If no term in the series ACD… is predicable of any term in the series BEF…, and if G- a term in the former series- is the genus of A, clearly G will not be the genus of B; since, if it were, the series would not be mutually exclusive. (PsA., A, 15, 79b6-11) 2. Atomic disconnection of series. Of two mutually exclusive series ACD and BEF, if neither A nor B has a genus and A does not inhere in B, this disconnection must be atomic. (PsA., A, 15, 79b6-14) G. Characteristics of relations of individuals 1. No individual in a species is more substance than another individual in another species. (Cat., 5, 2b26-28) An individual man, for instance, is no more a substance than an individual ox. 2. Each attribute is wider than every individual it is predicated on, though several attributes, collectively considered, might not be wider but exactly the substance of a thing. (PsA., B, 13, 96a32-b1) 3. Not distinguishing between class membership and class inclusion? Some commentators like Vlastos and Ackrill (1963, 76) criticized Aristotle because he, they believe, did not distinguish between class membership (between species and particulars) and class inclusion (between genera and their species). Having accepted this point, Daniel W. Graham believes it is ‘question-begging in a curious way.’ Phil Corkum thinks that Aristotle employs mereological notions. (This criticism seems so strange because all the Aristotle’s point in distinguishing species 2 from genera is strictly the distinction of class membership and class inclusion as they call them so.

After 50 years of debate, the ethics of aggregation has reached a curious stalemate, with both sides arguing that only their theory treats people as equals. I argue that, on the issue of equality, both sides are wrong. From the premise that “each counts for one,” we cannot derive the conclusion that “more count for more”—or its negation. The familiar arguments from equality to aggregation presuppose more than equality: the Kamm/Scanlon “Balancing Argument” rests on what social choice theorists call “(Positive) (...) Responsiveness,” Kamm’s “Aggregation Argument” assumes that “equal” lives are fungible, and Hsieh et al. have it that spreading goods broadly best approximates equality. In each case, the crucial premise is not equality itself but a further idea that Taurek, I argue, can safely reject. I conclude with a conjecture: there is no theory-neutral argument that settles the question of whether the numbers count. (shrink)

We argue that this is indeed psychologically possible, and thus far agree with Charles Camosy and Joseph Vukov in their recent paper on 'double effect donation.' Where we disagree with these authors is that we see double effect donation not as a morally praiseworthy act akin to martyrdom but as a morally impermissible act that necessarily disrespects human bodily integrity. Respect for bodily integrity (...) goes beyond avoiding the aim to kill: not all side effects of deliberate bodily interventions can be outweighed by intended benefits for another even if the subject fully consents. It is not any necessary intention to kill or harm another or oneself that makes lethal donation/harvesting illicit but the more immediate intention to accept or perform surgery on an (innocent) person combined with the foresight of lethal harm and no health-related good for him or her. Double effect donation falls foul of the first condition of double effect reasoning in that the immediate act is wrong in itself. We argue further that the wider effects of such donation would be socially disastrous and corrupting of the medical profession: doctors should retain a sense of nonnegotiable respect for bodily integrity even when they intervene on willing subjects for the benefit of others.

Can you rationally double-check what you already know? In this paper, I argue that you can. Agents can know that something is true and rationally double-check it at the very same time. I defend my position by considering a wide variety of cases where agents double-check their beliefs to gain epistemic improvements beyond knowledge. These include certainty, epistemic resilience, and sensitivity to error. Although this phenomenon is widespread, my proposal faces two types of challenges. First, some have (...) defended ignorance norms, on which agents are only allowed to inquire about things they don’t already know. Second—motivated by strong conceptions of belief or pragmatic encroachment—some have argued that doublechecking destroys knowledge. I argue that these competing views fail to capture both the epistemic value of double-checking and the many reasons why agents might double-check. Moreover, they rely on overly strong assumptions about what inquiry, knowledge, or belief requires. Finally, I marshal linguistic data in favor of the compatibility of knowledge and doublechecking.

The dead donor rule (DDR) prohibits retrieval protocols that would be lethal to the donor. Some argue that compliance with it can be maintained by satisfying the requirements of double‐effect reasoning (DER). If successful, one could support organ donation without reference to the definition of death while being faithful to an ethic that prohibits intentionally killing innocent human life. On the contrary, I argue that DER cannot make lethal organ donation compatible with the DDR, because there are plausible ways (...) it fails DER's requirements. A key takeaway is that the theories of intention and proportionality assumed in DER matter for its plausibility as a constraint on practical reasoning. (shrink)

DNA possesses a double nature: it is both an analog chemical compound and a digital carrier of information. By distinguishing these two aspects, this paper aims to reevaluate the legally and politically influential idea that the human genome forms part of the common heritage of mankind, an idea which is thought to conflict with the practice of patenting DNA. The paper explores the lines of reasoning that lead to the common heritage idea, articulates and motivates what emerges as the (...) most viable version of it, and assesses the extent to which this version conflicts with gene-patenting practices as exemplified by the U.S. regime. It concludes that the genome is best thought of as a repository of information to which humanity has a fiduciary relationship, and that on this view, the perceived conflict with gene-patenting largely dissolves.

I here defend historical entitlement theories of property rights against a popular charge. This is the objection that such theories fail because no convincing account of original appropriation exists. I argue that this argument assumes a certain reading of historical entitlement theory and I spell out an alternative reading against which it misfires. On this reading, the role of acts of original appropriation is not to justify but to individuate people’s holdings. I argue that we can identify which acts count (...) as original appropriation against the background of a general justification for a practice of property rights. On this view, what I will call ‘natural’ acts of original appropriation are acts by which a person begins to satisfy the general conditions for justified ownership. Finally, I offer an interpretation of John Locke's theory of appropriation along these lines and argue that it provides an attractive reading of his view. (shrink)

Does A cause B simply if A prevents what would have prevented B? Such a case is known as double prevention: where we have the prevention of a prevention. One theory of causation is that A causes B when B counterfactually depends on A and, as there is such a dependence, proponents of the view must rule that double prevention is causation.<br><br>However, if double prevention is causation, it means that causation can be an extrinsic matter, that the (...) cause and effect need not be connected by a continuous chain of events, that there can be causation by absence, and that there can be causation at a distance. All of these implications jar with strong intuitions we have about the nature of causation. There is, on the other hand, a theory of causation based on an ontology of real dispositions, where causation involves the passing around of powers. This theory in contrast entails that double prevention is not causation and, on this issue, it can claim a victory over the counterfactual dependence account. (shrink)

The ‘doctrine of double effect’ claims that it is in some sense morally less problematic to bring about a negatively evaluated state of affairs as a ‘side effect’ of one’s pursuit of another, morally unobjectionable aim than it is to bring it about in order to achieve that aim. In a first step, this chapter discusses the descriptive difference on which the claim is built. That difference is shown to derive from the attitudinal distinction between intention and ‘acceptance’, a (...) distinction that is in turn claimed to ground in a feature of the decisions that generate the attitudes in question. The resulting analysis is then plugged into two different normative principles that may each be thought to specify the intuitions behind the doctrine of double effect, but which have frequently been conflated. The first concerns the permissibility of bringing about the merely accepted state of affairs, the second its reduced attributability. It is argued that examination of the intuitions behind the two principles supports neither version of the doctrine. Rather, the intuitions are best captured in an attribution principle based on subjective probabilities and a principle of attitude evaluation, neither of which make explicit reference to the attitude of intending.

The U.S. Supreme Court's majority opinion in Vacco v. Quill assumes that the principle of double effect explains the permissibility of hastening death in the context of ordinary palliative care and in extraordinary cases in which painkilling drugs have failed to relieve especially intractable suffering and terminal sedation has been adopted as a last resort. The traditional doctrine of double effect, understood as providing a prohibition on instrumental harming as opposed to incidental harming or harming asa side effect, (...) must be distinguished from other ways in which the claim that a result is notintended might be offered as part of ajustification for it. Although double effectmight appropriately be invoked as a constrainton ordinary palliative care, it is not clearthat it can be coherently extended to justifysuch practices as terminal sedation. A betterapproach would reconsider double effect'straditional prohibition on hastening death as ameans to relieve suffering in the context ofacute palliative care. (shrink)

Many philosophers display relaxed scepticism about the Doctrine of Doing and Allowing and the Doctrine of Double Effect, suspecting, without great alarm, that one or both of these Doctrines is indefensible. This relaxed scepticism is misplaced. Anyone who aims to endorse a theory of right action with Nonconsequentialist implications should accept both the DDA and the DDE. First, even to state a Nonconsequentialist theory requires drawing a distinction between respecting and promoting values. This cannot be done without accepting some (...) deontological distinction. Second, if someone is going to accept any deontological distinction she should accept either the DDE or the DDA or some replacement. Finally, anyone who accepts either the DDE or the DDA should accept both doctrines or a replacement of each. Unless both Doctrines can be defended or given a defensible replacement, any Nonconsequentialist is in trouble. (shrink)

Number systems differ cross-culturally in characteristics like how high counting extends and which number is used as a productive base. Some of this variability can be linked to the way the hand is used in counting. The linkage shows that devices like the hand used as external representations of number have the potential to influence numerical structure and organization, as well as aspects of numerical language. These matters suggest that cross-cultural variability may be, at least in part, a (...) matter of whether devices are used in counting, which ones are used, and how they are used. (shrink)

We often speak as if there are merely possible people—for example, when we make such claims as that most possible people are never going to be born. Yet most metaphysicians deny that anything is both possibly a person and never born. Since our unreflective talk of merely possible people serves to draw non-trivial distinctions, these metaphysicians owe us some paraphrase by which we can draw those distinctions without committing ourselves to there being merely possible people. We show that such paraphrases (...) are unavailable if we limit ourselves to the expressive resources of even highly infinitary first-order modal languages. We then argue that such paraphrases are available in higher-order modal languages only given certain strong assumptions concerning the metaphysics of properties. We then consider alternative paraphrase strategies, and argue that none of them are tenable. If talk of merely possible people cannot be paraphrased, then it must be taken at face value, in which case it is necessary what individuals there are. Therefore, if it is contingent what individuals there are, then the demands of paraphrase place tight constraints on the metaphysics of properties: either (i) it is necessary what properties there are, or (ii) necessarily equivalent properties are identical, and having properties does not entail even possibly being anything at all.

I argue against the Doctrine of Double Effect’s explanation of the moral difference between terror bombing and strategic bombing. I show that the standard thought-experiment of Terror Bomber and Strategic Bomber which dominates this debate is underdetermined in three crucial respects: (1) the non-psychological worlds of Terror Bomber and Strategic Bomber; (2) the psychologies of Terror Bomber and Strategic Bomber; and (3) the structure of the thought-experiment, especially in relation to its similarity with the Trolley Problem. (1) If the (...) two worlds are not identical, then it may be these differences between the two worlds and not the Doctrine of Double Effect to explain the moral difference; (2a) if Terror Bomber and Strategic Bomber have the same causal beliefs, then why does Terror Bomber set out to kill the children? It may then be this unwarranted and immoral choice and not the Doctrine of Double Effect that explains the moral difference; (2b) if the two have different causal beliefs, then we can’t rule out the counterfactual that, had Strategic Bomber had the same beliefs as Terror Bomber, she would have also acted as Terror Bomber did. Finally, (3) the Strategic Bomber scenario could also be constructed so as to be structurally equivalent to the Fat Man scenario in the Trolley Problem: but then the Doctrine of Double Effect would give different answers to two symmetrical cases.

Categorical logic has shown that modern logic is essentially the logic of subsets (or "subobjects"). Partitions are dual to subsets so there is a dual logic of partitions where a "distinction" [an ordered pair of distinct elements (u,u′) from the universe U ] is dual to an "element". An element being in a subset is analogous to a partition π on U making a distinction, i.e., if u and u′ were in different blocks of π. Subset logic leads to finite (...) probability theory by taking the (Laplacian) probability as the normalized size of each subset-event of a finite universe. The analogous step in the logic of partitions is to assign to a partition the number of distinctions made by a partition normalized by the total number of ordered pairs |U|² from the finite universe. That yields a notion of "logical entropy" for partitions and a "logical information theory." The logical theory directly counts the (normalized) number of distinctions in a partition while Shannon's theory gives the average number of binary partitions needed to make those same distinctions. Thus the logical theory is seen as providing a conceptual underpinning for Shannon's theory based on the logical notion of "distinctions.". (shrink)

In The Souls of Black Folk, W.E.B. Du Bois introduces double consciousness as a result of racial prejudice and oppression. Explained as a state of confliction felt by black Americans, Du Bois presents double consciousness as integral to understanding the black experience. Later philosophers question the importance of double consciousness to current race discussions, but this paper contends that double consciousness provides valuable insights into black and white relations. To do this, I will utilize the modern (...) slang term, “Oreo,” to highlight how a perceived incompatibility between blacks and whites could prevent America from achieving a greater unity. (shrink)

“Double-halfers” think that throughout the Sleeping Beauty Scenario, Beauty ought to maintain a credence of 1/2 in the proposition that the fair coin toss governing the experimental protocol comes up heads. Titelbaum (2012) introduces a novel variation on the standard scenario, one involving an additional coin toss, and claims that the double-halfer is committed to the absurd and embarrassing result that Beauty’s credence in an indexical proposition concerning the outcome of a future fair coin toss is not 1/2. (...) I argue that there is no reason to regard the credence required by the double-halfer as any less acceptable than the one deemed required by Titelbaum. (shrink)

S. C. Gibb holds that some mental events enable physical events to take place by acting as ‘double preventers’ which prevent other mental events from effecting change in the physical domain. She argues that this enables a dualist account of psychophysical interaction consistent with the causal relevance of mental events, their distinctness from physical events, the causal closure of the physical and the exclusion of systematic overdetermination. While accepting the causal powers metaphysic, this paper argues that: Closure is maintained (...) only on the assumption of an implausible pre-ordained harmony between preventing and double-preventing mental events. Distinctness is preserved only at the cost of positing brute unexplained powers of mental and physical events to causally interact with each other. Exclusion is systematically violated in a substantial number of everyday cases. The case for Relevance made by the Double Prevention model is accordingly too weak to sustain a dualist approach to mental causation. (shrink)

Double-entry bookkeeping (DEB) implicitly uses a specific mathematical construction, the group of differences using pairs of unsigned numbers ("T-accounts"). That construction was only formulated abstractly in mathematics in the 19th century—even though DEB had been used in the business world for over five centuries. Yet the connection between DEB and the group of differences (here called the "Pacioli group") is still largely unknown both in mathematics and accounting. The precise mathematical treatment of DEB allows clarity on certain conceptual questions (...) and it immediately yields the generalization of the double-entry method to multi-dimensional vectors typically representing the different types of property involved in an enterprise or household.

Many ethicists maintain that medical research on human subjects that presents no prospect of direct medical benefit must have a prospect of social benefit to be ethical. Payment is not the sort of benefit that justifies exposing subjects to risk. Alan Wertheimer has raised a serious challenge to this view, pointing out that in industry, social value is not considered necessary to make dangerous jobs ethical. This article argues that Wertheimer was correct to think that the ethics of hazard pay (...) should be the same in medical research and in business. Nevertheless, a qualified social benefit requirement should apply in both fields. For a study or a job with significant net physical risk to be ethical, it must have social value beyond the satisfaction of ordinary preferences, including the preference for money. The requirement derives from a non-absolutist version of the doctrine of double effect. If a risky study or a dangerous job has no distinctive social value, and hazard pay is subjects' or workers’ only reason to undergo risks, the very fact that they undergo risk is intended as a means to a financial end. Inviting people to enrol in such a study or to take such a job wrongfully treats people as mere means. By contrast, if a study or a job has social value, people can participate with a primary end other than money, even if they accept compensation. Researchers or employers do not intend but merely foresee risks to subjects or workers. (shrink)

In an important and widely cited paper, Zerilli, Knott, Maclaurin, and Gavaghan (2019) argue that opaque AI decision makers are at least as transparent as human decision makers and therefore the concern that opaque AI is not sufficiently transparent is mistaken. I argue that the concern about opaque AI should not be understood as the concern that such AI fails to be transparent in a way that humans are transparent. Rather, the concern is that the way in which opaque AI (...) is opaque is very different than the way in which humans are opaque. What matters is the degree to which the opaque processes of a class of decision makers are stable, uniform, and safe. The degree to which such processes have these features in humans is higher than the degree to which such processes have these features in opaque AI. And therefore we should require AI to be more transparent than humans. (shrink)

The paper provides an analysis of Martin Buber’s intellectual conversion and shows how it facilitates a deeper understanding of the phenomenon of nationalism. Buber, who is today known mainly as a key representative of dialogical philosophy, was in the 1910s part of the double wave of German and Jewish nationalism which strongly affected the German-speaking Jewish public. Buber provided intellectual support for this wave of nationalism and interpreted World War I as a unique chance for the spiritual unification of (...) European Jewry. Consequent to his conflict with Gustav Landauer Buber underwent a complex intellectual and existential transformation. He abandoned key concepts of his pre-dialogical thought and laid the foundations of his dialogical thought. He rejected his endorsement of Geman nationalism and substantially reevaluated his political positions. The analysis of Buber’s intellectual development sheds light on some important aspects of the dynamics of nationalism. (shrink)

The “principle of double effect” is a vital tool for moral decision making and is applicable to all areas of medical practice, including (for example) end-of-life care, transplant medicine, and cases of conscientious objection. Both our ultimate and our more immediate intentions are relevant in making and evaluating choices— though side effects must be kept proportionate and can be morally conclusive when linked with some intentions. Intentions help to form the character of doctors, and of human beings generally. While (...) hypocrisy is certainly possible in regard to this form (and other forms) of moral reasoning, double effect reasoning, sincerely practised, remains indispensable in identifying moral problems and solutions.

My aim in this paper is to carve out a political understanding of the Muslim identity. The Muslim identity is shaped within a religious mold. Inseparable from this religious understanding is a political one that is valuable in its own right in order to secure any sustainable possibility of participating politically as Muslims within a democratic liberal democracy, such as the United States. Here I explore not the historical or theological formation of the Muslim identity, rather a metaphysical understanding of (...) it, in order to mobilize politically while avoiding the traps of essentialism. I begin with a brief overview of the early understandings of the term “identity politics” in the United States. Moving beyond interest-based movements I explore María Lugones' particular understanding of the self as multiplicitous. I then offer examples of the Muslim identity within the context of a social movement and individualist claims, in order to draw out the political aspects of the Muslim identity. In the final section I argue that the theological criteria that define “who counts as a Muslim” is a crucial aspect of how many Muslims may understand their identity as Muslims. However, I claim that in order to avoid the traps of marginalization of Muslim minorities, one must understand oneself as a multiplicitous political agent and that, furthermore, such an understanding is not at odds with Islam or one's own understanding of their identity as Muslim.

I identify and resolve an internal tension in Critical Contextual Empiricism (CCE) – the normative account of science developed by Helen Longino. CCE includes two seemingly conflicting principles: on one hand, the cognitive goals of epistemic communities should be open to critical discussion (the openness of goals to criticism principle, OGC); on the other hand, criticism must be aligned with the cognitive goals of that community to count as “relevant” and thus require a response (the goal-relativity of response-requiring criticism principle, (...) GRC). The co-existence of OGC and GRC enables one to draw both approving and condemning judgments about a situation in which an epistemic community ignores criticism against its goals. This tension results from conflating two contexts of argumentation that require different regulative standards. In the first-level scientific discussion, GRC is a reasonable principle but OGC is not; in the meta-level discussion about science, the reverse holds. In meta-level discussion, the relevance of criticism can be established by appealing to goals of science that are more general than the goals of a specific epistemic community. To illustrate my revision of CCE, I discuss why feminist economists’ criticism of the narrowness of the goals pursued in mainstream economics is relevant criticism. (shrink)

Suppose that we repair a wooden ship by replacing its planks one by one with new ones while at the same time reconstructing it using the discarded planks. Some defenders of vague or indeterminate identity claim that: (1) although the reconstructed ship is distinct from the repaired ship, it is indeterminate whether the original ship is the reconstructed ship and indeterminate whether it is the repaired ship, and (2) the indeterminacy is due to the world and not just an imprecision (...) in the language used to describe the situation. I argue that such a description is incoherent. The argument has two features. First, it differs in spirit from Gareth Evans's more general famous proof against the possibility of indeterminate identity. This is because I rely on facts regarding counting and sets. Second, I focus on Terence Parsons's recent defence of indeterminate identity. I argue that his attempts at making sense of counting objects involving indeterminate identities fail on technical and philosophical grounds. (shrink)

Since the last ice age, when ice enveloped most of the northern continents, the earth has warmed by about five degrees. Within a century, it is likely to warm by another four or five. This revolution in our climate will have immense and mostly harmful effects on the lives of people not yet born. We are inflicting this harm on our descendants by dumping greenhouse gases into the atmosphere. We can mitigate the harm a little by taking measures to control (...) our emissions of these gases, and to adapt to the changes by, for instance, building sea walls around coastlines threatened by rising sea levels. But these measures will be very expensive, and the costs will be born by us, the present generation, whereas the benefits will come to future generations. How much should we sacrifice for the sake of the future? Economists and philosophers have independently worked on the question of our responsibility to future generations. This book brings their work together and applies it to global warming. It suggests a programme for future research on the economic and ethical issues. The book is intended for economists, and for philosophers and other social scientists who have a little knowledge of economic methods. (shrink)

This paper addresses the problem of sound individuation (SI) and its connection to sound ontology (SO). It is argued that the problems of SI, such as aspatiality, extreme individuation, indexical perplexity and duration puzzles are due to SO’s uncertainties. Besides, I describe the views in SO, including the wave view (WV), the property view (PV), and the event view (EV), as Casey O’Callaghan defends it. According to O’Callaghan, EV offers clear standards to individuate sounds. However, this claim is countered by (...) the consideration that any view could also defend the standards in SO, and thus, EV does not solve any of the problems mentioned above. As a way of showing the difficulties inherited by sound’s inner ontology, the problem of its linguistic representation is also addressed. The problem of SI can be developed within the frame of the philosophy of language and, specifically, regarding the discussion about mass vs count-­sortal terms. Is the term sound a mass or a count­-sortal? It is shown that, for reasons pertaining SO, the decision regarding the case of sound as a mass or count-­sortal term remains open. SI is, thus, covered from the SO to the philosophy of language. (shrink)

The Double Content view is the first comprehensive theory of art that is able to satisfactorily explain the nature of all kinds of artworks in a unified way — whether paintings, novels, or musical and theatrical performances.

In The Matter of Consciousness, in the course of his extended discussion and defense of Frank Jackson’s famous knowledge argument, Torin Alter dismisses some objections on the grounds that they are cases of cheating. Though some opponents of the knowledge argument offer various scenarios in which Mary might come to know what seeing red is like while still in the room, Alter argues that the proposed scenarios are irrelevant. In his view, the Mary case is offered to defend the claim (...) that phenomenal facts cannot be a priori deduced from physical facts. Thus, a proposed scenario constitutes an objection to the knowledge argument only if it presents a case in which Mary’s learning inside the room comes about via a priori deduction from physical facts. Call this the deducibility standard. In what follows, I’ll explore a series of relevant cases in an effort to clarify this standard. Doing so enables us to better understand how cheating should be assessed in this context and thereby also to get clearer on the argumentative dialectic surrounding the Mary case. (shrink)

It seems rather intuitive that if I can save either one stranger or five strangers, I must save the five. However, Kantian (and other non-consequentialist) views have a difficult time explaining why this is the case, as they seem committed to what Parfit calls “innumeracy”: roughly, the view that the values of lives (or the reasons to save them) don’t get greater (or stronger) in proportion to the number of lives saved. This chapter first shows that in various cases, it (...) is permissible to save fewer lives, contrary to what is implied by “numerate” views. Then it argues that in the cases in which it is intuitive that we must save the greater number, Kantians (and other deontologists) can not only deliver this verdict but also explain why it is correct, without presupposing that the value of our action depends on “adding up” the values of the lives saved.

Although the fictional domain exhibits a prima facie freedom from real-world moral constraints, certain fictive imaginings seem to deserve moral criticism. Capturing both intuitions, this paper argues for double-standard moralism, the view that fictive imaginings are subject to different moral standards than their real-world counterparts. I show how no account has, thus far, offered compelling reasons to warrant the moral appropriateness of this discrepancy. I maintain that the normative discontinuity between fiction and the actual world is moderate, as opposed (...) to one that leaves fictive engagements wholly exempt from moral evaluations. I propose a way of addressing the gamer’s dilemma that is compatible with a moderate kind of discontinuity. Finally, I contend that the audience is justified in adopting deviant moral attitudes in fictional situations because their consequences largely differ from those that analogous real-world events would have.
