There is a renewed debate about modus ponens. Strikingly, the recent counterexamples in Cantwell, Dreier and MacFarlane and Kolodny are generated by restricted readings of the ‘if’-clause. Moreover, it can be argued on general grounds that the restrictor view of conditionals developed in Kratzer and Lewis leads to counterexamples to modus ponens. This paper provides a careful analysis of modus ponens within the framework of the restrictor view. Despite appearances to the contrary, there is a (...) robust sense in which modus ponens is valid, owing to the fact that conditionals do not only allow for restricted readings but have bare interpretations, too.

The view that if-clauses function semantically as restrictors is widely regarded as the only candidate for a fully general account of conditionals. The standard implementation of this view assumes that, where no operator to be restricted is in sight, if-clauses restrict covert epistemic modals. Stipulating such modals, however, lacks independent motivation and leads to wrong empirical predictions. In this paper I provide a theory of conditionals on which if-clauses are uniformly interpreted as restrictors, but no covert (...) modals are postulated. Epistemic if-clauses, like those in bare conditionals, restrict an information state parameter which is used to interpret an expressive layer of the language. I show that this theory yields an attractive account of bare and overtly modalized conditionals and solves various empirical problems for the standard view, while dispensing with its less plausible assumption.

The problem of probabilities of conditionals is one of the long-standing puzzles in philosophy of language. We defend and update Adams' solution to the puzzle: the probability of an epistemic conditional is not the probability of a proposition, but a probability under a supposition. -/- Close inspection of how a triviality result unfolds in a concrete scenario does not provide counterexamples to the view that probabilities of conditionals are conditional probabilities: instead, it supports the conclusion that probabilities (...) of conditionals violate standard probability theory. -/- This does not call into question probability theory per se; rather, it calls for a more careful understanding of its role: probability theory is a theory of probabilities of propositions; but as conditionals do not express propositions, their probabilities are not subject to the standard laws. -/- We argue that both conditional probabilities and probabilities of conditionals are best understood in terms of the dynamics of supposing, modeled as a restriction operation on a probability space. This version of the suppositionalist view allows us to connect Adams' Thesis to the widely held restrictor view of the semantics of conditionals. -/- We address two common objections to Adams' view: that the relevant probabilities are ‘probabilities only in name’, and that giving up conditional propositions puts us at a disadvantage when it comes to interpreting compounds. -/- Finally, we argue that some putative counterexamples to Adams' Thesis can be diagnosed as fallacies of probabilistic reasoning: they arise from applying to conditionals laws of standard probability theory which are invalid for them.

Many languages allow for “fake” uses of their past tense marker: the marker: can occur in certain contexts without conveying temporal pastness. Instead it appears to bear a modal meaning. Iatridou :231–270, 2000) has dubbed this phenomenon Fake Tense. Fake Tense is particularly common to conditional constructions. This paper analyzes Fake Tense in English conditional sentences as a certain kind of ambiguity: the past tense morphology can mark the presence of a temporal operator, but it can also signal a specific (...) modal operator. The ambiguity is proposed to be the result of recategorization: the Simple Past develops a second, modal meaning because of structural similarities between the temporal and the modal/epistemic domain. The proposal is spelled out in the generative semantics framework, using the restrictor approach to conditionals Semantics from different points of view, 1979; in: A. von Stechow and D. Wunderlich Semantics: an international handbook of contemporary research, 1991), and building on von Stechows et al.’s recent work on the English tense system The expression of time in language, 2010; Romero and von Stechow, Tense: introduction, 2008).

We bring together two ideas that are widely accepted in the literature: (i) conditionals with modal consequents are systematically ambiguous between a reading on which the if-clause restricts the modal, and a reading on which the if-clause introduces an epistemic supposition and the modal is unrestricted; (ii) ‘will’ is a modal. Together, (i) and (ii) imply that ‘will’-conditionals are systematically ambiguous between a reading as restricted historical claims, and one as unrestricted historical claims made under a supposition. We (...) argue that this prediction is correct and that the existence of the relevant ambiguity has far-reaching repercussions for several important debates concerning conditionals. (shrink)

I argue that normative requirements should be interpreted as the conditional obligations of dyadic deontic logic. Semantically, normative requirements are conditionals understood as restrictors, the prevailing view of conditionals in linguistics. This means that Modus Ponens is invalid, even when the premises are known.

Background conditions are thought to explain how objects can have value in virtue of certain features and how reasons can consist in certain facts. The following paper provides an account of what background conditions are and what effect they have on normative features. It defends the idea that if values depend on reasons, then there is nothing really surprising or mysterious about the presence of background conditions in normative explanations. Background conditions turn out to be a natural and predictable result (...) of normative hierarchies that treat reasons as metaphysically fundamental relative to other normative features. The account is also shown to have advantages over competing accounts in that it is able to capture the functional criteria that characterize background conditions while remaining theoretically parsimonious.

This paper investigates some aspects of the semantics of deontic should-conditionals. The main objective is to understand which actual world facts make deontic statements true. The starting point for the investigation is a famous puzzle known as Chisholm’s Paradox. It is important because making sense of the data in Chisholm-style examples involves arriving at some conclusion regarding the interaction between what we consider ideal and what is actually true. I give an account of how facts affect the evaluation of (...) should formulated in a way that does not predict that the divergence between ideals and facts leads to contradictions. The proposed semantics for should and should-conditionals allows for factual detachment without giving rise to paradoxes. The proposal has several parts: a situation-based semantics for the modal should, a view of the propositions embedded under should that allows aspect to play a crucial role in anchoring propositions to the context set, and a proposal for if-clauses that distinguishes between epistemic if-clauses and if-clauses in the scope of should, treating the latter as restrictors on the quantificational domain of the modal.

This doctoral dissertation investigates what influence indicative conditionals have on belief updating and how learning from conditionals may be modelled in a probabilistic framework. Because the problem is related to the interpretation of conditionals, we first assess different semantics of indicative conditionals. We propose that conditionals should be taken as primary concepts. This allows us to defend a claim that learning a conditional is equivalent to learning that the relevant conditional probability is 1. This implies (...) that learning a conditional can be modelled as learning a material conditional. We then turn to a few competing approaches to the problem of learning from a conditional -- an approach that models these situations with regards to changes in the explanatory status of the antecedent, as minimising probability distances between the prior and posterior probability distributions, and, particularly, an approach based on epistemic entrenchment. It is argued that although all approaches are important for their pioneering contributions, none of them ultimately provides a fully satisfactory solution. We then formulate a proposal according to which learning a conditional may be modelled as learning a material conditional in conjunction with other contextually inferred or observed information. We show that the view has an intuitive appeal on the grounds of pragmatics and empirical research in psychology of reasoning. We also show that the proposed approach successfully resolves all standard cases from the literature. The proposal is then extended to left-nested conditionals. To do so, we first inspect some preliminary empirical data about actual reasoning with nested conditionals and then show that the proposed approach also successfully models these cases. We then investigate how the approach may be extended to the so-called imperative conditionals. We introduce a tripartite typology of imperative conditionals and argue that although imperatives cannot be probabilistically modelled in any straight-forward way, at least some general insights of the proposed method help us understand the influence that the three different types of imperative conditionals have on listeners’ beliefs. We conclude with a summary and some open questions that should be addressed in future work (e.g. the influence of counterfactuals on belief updating). (shrink)

This paper introduces a new argument against Richard Foley’s threshold view of belief. His view is based on the Lockean Thesis (LT) and the Rational Threshold Thesis (RTT). The argument introduced here shows that the views derived from the LT and the RTT violate the safety condition on knowledge in way that threatens the LT and/or the RTT.

In order to resolve the controversial discussion regarding content effects in deductive reasoning, we propose distinguishing between two inferential sources—an argument's form , and additional relations people associate with the argument's content —and analysing their interplay. Both sources are equally necessary in order to understand the role content plays in deductive reasoning. People make valid deductions from the content relations ( content competence ), but in thematic reasoning tasks, these deductions lead to the intriguing phenomenon known as content effects . (...) Focusing on the interplay of both sources of inferences, the dual source distinction enables a novel class of predictions to be made, namely the correct mastery of the logical connectors ( form competence ) in tasks that require the individual to think about an argument's form in relation to its content. To illustrate the dual source approach and its implications, the selection task paradigm of conditional reasoning with a point of view is used in combination with two content domains: conditional promises with cheating and non-cheating perspectives and technical systems with causal perspectives. Experimental findings corroborate all three phenomena: content competence, content effects, and form competence. The dual source distinction is discussed with regard to current theories of reasoning.

Conditional logics were originally developed for the purpose of modeling intuitively correct modes of reasoning involving conditional—especially counterfactual—expressions in natural language. While the debate over the logic of conditionals is as old as propositional logic, it was the development of worlds semantics for modal logic in the past century that catalyzed the rapid maturation of the field. Moreover, like modal logic, conditional logic has subsequently found a wide array of uses, from the traditional (e.g. counterfactuals) to the exotic (e.g. (...) conditional obligation). Despite the close connections between conditional and modal logic, both the technical development and philosophical exploitation of the latter has outstripped that of the former, with the result that noticeable lacunae exist in the literature on conditional logic. My dissertation addresses a number of these underdeveloped frontiers, producing new technical insights and philosophical applications. -/- I contribute to the solution of a problem posed by Priest of finding sound and complete labeled tableaux for systems of conditional logic from Lewis' V-family. To develop these tableaux, I draw on previous work on labeled tableaux for modal and conditional logic; errors and shortcomings in recent work on this problem are identified and corrected. While modal logic has by now been thoroughly studied in non-classical contexts, e.g. intuitionistic and relevant logic, the literature on conditional logic is still overwhelmingly classical. Another contribution of my dissertation is a thorough analysis of intuitionistic conditional logic, in which I utilize both algebraic and worlds semantics, and investigate how several novel embedding results might shed light on the philosophical interpretation of both intuitionistic logic and conditional logic extensions thereof. -/- My dissertation examines deontic and connexive conditional logic as well as the underappreciated history of connexive notions in the analysis of conditional obligation. The possibility of interpreting deontic modal logics in such systems (via embedding results) serves as an important theoretical guide. A philosophically motivated proscription on impossible obligations is shown to correspond to, and justify, certain (weak) connexive theses. Finally, I contribute to the intensifying debate over counterpossibles, counterfactuals with impossible antecedents, and take—in contrast to Lewis and Williamson—a non-vacuous line. Thus, in my view, a counterpossible like "If there had been a counterexample to the law of the excluded middle, Brouwer would not have been vindicated" is false, not (vacuously) true, although it has an impossible antecedent. I exploit impossible (non-normal) worlds—originally developed to model non-normal modal logics—to provide non-vacuous semantics for counterpossibles. I buttress the case for non-vacuous semantics by making recourse to both novel technical results and theoretical considerations. (shrink)

Assisted dying is a divisive and controversial topic and it is therefore desirable that a broad range of interests inform any proposed policy changes. The purpose of this study is to collect and synthesize the views of an important stakeholder group—namely people with disabilities —as expressed by disability rights organisations in Great Britain. Parliamentary consultations were reviewed, together with an examination of the contemporary positions of a wide range of DROs. Our analysis revealed that the vast majority do not have (...) a clear public stance; those that do exhibit a significant diversity of opinion. DROs opposing legislation on assisted dying have argued that it would be premature, misguided, inequitable and culturally undesirable. Some specify conditions that would have to be satisfied before they could support legalisation, such as radical improvements in health and social care services and the elimination of discrimination against PwD. DROs supporting assisted dying maintain that a change in the law would promote autonomy, end intense suffering, can be delivered safely and is supported by the DRO’s membership. The discussion considers the reasons why several DROs adopt a neutral stance and the argument is made that, whatever their overarching stance on the issue, DROs need to be involved in the policy debate so that the crucial perspectives of PwD are heard and addressed. This is an important message for countries around the world that permit, or are considering legalising, assisted dying. (shrink)

A globally expressivist analysis of the indicative conditional based on the Ramsey Test is presented. The analysis is a form of ‘global’ expressivism in that it supplies acceptance and rejection conditions for all the sentence forming connectives of propositional logic (negation, disjunction, etc.) and so allows the conditional to embed in arbitrarily complex sentences (thus avoiding the Frege–Geach problem). The expressivist framework is semantically characterized in a restrictor semantics due to Vann McGee, and is completely axiomatized in a logic (...) dubbed ICL (‘Indicative Conditional Logic’). The expressivist framework extends the AGM (after Alchourron, Gärdenfors, Makinson) framework for belief revision and so provides a categorical (‘yes’–‘no’) epistemology for conditionals that complements McGee’s probabilistic framework while drawing on the same semantics. The result is an account of the semantics and acceptability conditions of the indicative conditional that fits well with the linguistic data (as pooled by linguists and from psychological experiments) while integrating both expressivist and semanticist perspectives.

In this paper, I argue that Steadfast Views of peer disagreement – a family of views according to which standing firm in the face of peer disagreement can be rationally permissible -- are incoherent. First, I articulate two constraints that any Steadfast Views of disagreement should endorse: (i) Steadfastness’s Core (ii) The Deference Principle. I show that (i) and (ii) are inconsistent: they cannot both be true. My argument, briefly put, is that one cannot rationally treat one’s peer’s opinion as (...) unconditionally relevant to a hypothesis, H, but conditional on the supposition of a disagreement, irrelevant to H. Because Steadfast Views endorse a set of mutually inconsistent propositions, I conclude that Steadfast Views are incoherent. (shrink)

It is a striking fact from reverse mathematics that almost all theorems of countable and countably representable mathematics are equivalent to just five subsystems of second order arithmetic.

In lieu of an abstract, here is a brief excerpt of the content:396 Feminist Studies 44, no. 2. © 2018 by Feminist Studies, Inc. Lisa Rofel A View of Women’s Studies from Afar and Near As a member of the editorial collective of Feminist Studies, I have had the pleasure of reading the submissions to this special issue on the state of women’s, gender, feminist, and sexuality (WGFS) studies programs. All the accepted articles highlight why WGFS studies programs have (...) been, and continue to be, a vital part of intellectual training in US academies. I read the submissions from a particular perspective: that of having been trained in a discipline I happen to love, cultural anthropology, and at the same time always having been a feminist scholar within my discipline. When I was deciding which PhD program to enter, feminist anthropology was beginning to garner much attention. Along with feminist historians, feminist anthropologists were not only trying to include women in the picture, but were asking instead how attention to gender transforms the big questions about politics, social relations, and cultural meanings. This feminist approach would forever change how anthropologists analyze culture and power. Since I was both a feminist and an anti-imperialist activist, anthropology felt like the right discipline to choose. That might seem like a strange juxtaposition—anti-imperialism and anthropology—for those not familiar with the history of the discipline. When I entered graduate school, some anthropologists had already begun the self-critique of the discipline and its collusions with colonialism. As I moved through my graduate program, I was part of the creative efforts to figure out what kind of anthropology we could Lisa Rofel 397 foster that would be anti-colonial as well as post-colonial. It was a heady and exciting time to experience how we could develop a critique of culture and power. Reading over the submissions for this special issue, I was reminded of feeling troubled by those students in interdisciplinary programs (and not just from WGFS studies programs) who approach faculty in conventional disciplines only for training in methods. Frankly, I am very tired of being treated this way. In my discipline, methods are tied to the kinds of theoretical questions someone wants to ask. Texts that explain, for example, how to do an oral life history demonstrate how the method is tied to analytical/political questions. One of the best texts in this vein is Sherna Gluck and Daphne Patai’s Women’s Words: The Feminist Practice of Oral History.1 We never train our students merely in how to engage in participant-observation or how to conduct an interview, but rather how to think analytically about what the student wants to ask in the first place. For example, one of the graduate students I work with, Kali Rubaii, just finished her PhD dissertation, “Counterinsurgency and the Ethical Life of Material Things in Iraq’s Anbar Province,” for which she also did analogous research in the Palestinian territories. In such conditions, one has to think very carefully about how one works with—rather than does research on—the people whose horrendous living conditions (thanks to US imperialism) under what Rubaii calls “less-than-lethal counterinsurgency” matter a great deal for the rest of us to understand.2 Rather than interview them or do something called participant-observation, Rubaii did what she calls “transhumant ethnography,” which meant she decided that ethically she had to live through everything that her interlocutors were living through, including constantly moving from one unsafe or only temporarily safe place to another. Rubaii’s work, as an example, reminds us that methods are inextricably linked with the power dynamics infusing the worlds we study. In addition to the matter of methods, I am concerned about a problematic assumption that what distinguishes and even defines WGFS 1.

According to what is now commonly referred to as “the Equation” in the literature on indicative conditionals, the probability of any indicative conditional equals the probability of its consequent of the conditional given the antecedent of the conditional. Philosophers widely agree in their assessment that the triviality arguments of Lewis and others have conclusively shown the Equation to be tenable only at the expense of the view that indicative conditionals express propositions. This study challenges the correctness of (...) that assessment by presenting data that cast doubt on an assumption underlying all triviality arguments. (shrink)

The view of human in Confucian philosophy in Pre Qin Dynasty arose not only from the change in socio-economic conditions but also from the deterioration of social morality.

This paper aims to offer a new metaphysical view of both the representational content and the phenomenal or conscious character of visual experience inspired by Kaplan’s semantics of demonstratives. In Kaplan’s famous account, the character or meaning of a demonstrative type is understood as the function of a particular token of that type (vehicle of content) in the context of the demonstration of the singular content in the context in question. By way of analogy, I want to suggest that (...) the phenomenal character of experience can be best modeled as a function from tokens of experience in the context of experiential contact to their singular contents: that is, the instantiation of properties with which the subject is in experiential contact in those contexts. Since the meaning of demonstratives can also be described by its token-reflexive rule (the object demonstrated by this token demonstrative in this context of demonstration), we can also think of the phenomenal character as a token-reflexive property of representing whatever is normally causally responsible for this token experience in the context of experiential contact. This is what I call Reflexionism, inspired by Tye’s Kaplanianism (Tye 2009, 113-4, 2014). For example, phenomenal yellowness is the token-reflexive property of representing whatever is causally responsible for the relevant brain pattern in the context of experiential contact under normal conditions.

According to the subset view of realization, a property realizes another if the causal powers of the latter are a subset of those of the former. Against this view, some authors (in particular, Kevin Morris and Paul Audi) have argued that it has an untenable consequence that realizing properties are less fundamental than the properties they realize, because the subset view characterizes realized properties as parts (subsets) of their realizers whereas it is generally true that a part (...) is prior to its whole. This paper defends the subset view from this “part-whole” objection, by arguing that if we compare individual powers of realizer and realizee with particular attention to their manifestation conditions, it turns out that each power of a realizee is grounded in some power of its realizer. This grounding relation between powers, I shall argue, allows subset theorists to explain why a realizer is more fundamental than its realizee, even while having the latter as a part. (shrink)

In this paper, I engage the debate on Suits’ theory of games by providing a Kantian view of Utopia. I argue that although the Kantian aspects of Suits’ approach are often overlooked in comparison to its Socratic-Platonic aspects, Kant’s ideas play a fundamental role in Suits’ proposal. In particular, Kant’s concept of ‘regulative idea’ is the basis of Suits’ Utopia. I regard Utopia as Suits’ regulative idea on game playing. In doing so, I take Utopia to play a double (...) role in Suits’ theory of games. First, it highlights the primary condition of possibility of game-playing, namely, the lusory attitude. Second, it provides a normative criterion that serves as a critical principle to evaluate instances of game playing and as a counterfactual assumption that makes game playing possible. I provide further support for my Kantian interpretation of Suits’ Utopia by bringing to light the anthropological assumptions upon which Utopia is built. In doing so, I argue that both Suits’ theory of games, in general, and his Utopia, in particular, lay out the conditions of possibility of game playing, not an analysis on the life most worth living.

Church is one of the fundamental terms of Christian theology. It is accepted that the roots of the concept of the church, defined today as “the congregation or community of people who are baptized and adopt the same basic Christian values” are in the Old Testament. The concept of the church has had different usages throughout history. With the emergence of Christianity, the concept began to be used to describe the community of people belonging to this religion. From early Christianity, (...) much has been written down about the concept of the church by people called “church fathers” considered to be authorities on religious matters. In this context, in this article, their approaches to the concept of the church have been examined by using the English translations of the works written by the church fathers and the studies on them. It is aimed to reveal the similarities and differences between their views on the concept of the church, their reasons, the points they attach importance while explaining the subject and their views on baptism. In the article in which the descriptive method is used, after the opinions of the church fathers shaped around the concept of the church are revealed, analysis and determinations have been made about them. In these determinations and analyzes, it is tried to explain how the personal characteristics of the church fathers as well as the cultural, historical, and periodical conditions are affective in the definition of the concept of the church.

Farmers’ decisions to conserve natural resources generally and soil and water particularly are largely determined by their knowledge of the problems and perceived benefits of conservation. In Ethiopia, however, farmer perceptions of erosion problems and farmer conservation practices have received little analysis or use in conservation planning. This research examines farmers’ views of erosion problems and their conservation knowledge and practices in the Beressa watershed in the central highlands of Ethiopia. Data were obtained from a survey of 147 farm households (...) managing 713 fields during the 2002/2003 cropping season. In-depth interviews and group discussions were also held with the farmers to obtain additional information. The results show that 72% of the farmers reported erosion problems, and they recognized that conservation was necessary. However, they considered erosion to be severe mostly when visible signs – rills and gullies – appeared on their fields. The majority of the farmers believe that erosion could be halted, and they use a range of practices for erosion control and fertility improvement. These include contour plowing (83%), drainage ditches (82%), and stone terraces/bunds (73%). Nevertheless, despite decades of conservation intervention in the area, it appears that most farmers have developed negative attitudes towards externally recommended measures. The research concludes that under the conditions present in the Ethiopian central highlands, soil and water conservation interventions should consider farmers’ conservation knowledge and practices to improve acceptance and adoption of the recommendations.

Conditional probability is often used to represent the probability of the conditional.

I argue that these assumptions come from a theory called the operator theory and that the rival (...) class='Hi'>restrictor theory can avoid these problematic assumptions. In doing so, I argue that recent extensions of the triviality arguments to restrictor conditionals fail, making assumptions which are only justified on the operator theory. (shrink)

The main aim of our paper is to implement Leibniz's analysis of the conditional right in the framework of a dialogical approach to Public Announcement Logic. According to our view, on one hand: PAL furnishes a dynamic epistemic operator which models communication exchange between different agents that seems to be very close to Leibniz understanding of the dynamics between the truth of a proposition and the knowledge of the truth of that proposition (Leibniz calls the latter certification of its (...) truth); on the other hand, the dialogical approach provides a semantics for the dynamic epistemic operator in the context of conditional right by means of which: (i) the exchange between agents leading to a public announcement amounts to the (contractual) interaction of commitments of both the benefactor and the beneficiary of a conditional right (ii) the notion of certification is understood as an action, namely as a move where the beneficiary asks the benefactor to stand to his commitments, (iii) some restrictions specific to the logical nature of the head and the tail of the conditional right can be implemented by combining PAL with some features of linear logic within the same theory of meaning.

Formal views of autonomy rule out substantive rational capacities (reasons-responsiveness) as a condition of autonomous agency. I argue that such views face a number of underappreciated problems: they have trouble making sense of how autonomous agents could be robustly responsible for their choices, face the burden of explaining why there should be a stark distinction between the importance of factual and evaluative information within autonomous agency, and leave it mysterious why autonomy is the sort of thing that has value and (...) ought to be promoted. Moreover, I argue that the alternative view that includes substantive rational capacities need not have the unacceptable political implications it is sometimes thought to have. (shrink)

The growth of the Pentecostal movement in the global south implies that its pneumatological emphases be noticed by other Christian traditions, including the hermeneutical processes followed to interpret the Bible, the Christians’ source of revelation about God.

Whilst the (...) Reformed tradition, for the better part, concentrates on scientific and rational hermeneutics, in part neglecting the subjective influence of the Spirit in the processes of interpretation, John Calvin uses it as a hermeneutical principle. An attempt is made to compare and contrast Calvin’s and classical Pentecostals’ views by way of a comparative literature study. It is concluded that a pneumatological basis should serve as a condition for representative biblical hermeneutics. It implies that the church can benefit from revisiting its hermeneutics ecumenically with a definite consideration of the role of the Spirit in the processes of interpreting the Bible for contemporary people. Contribution: In reading and interpreting the Bible, what role does the Holy Spirit play? The article asserts that a pneumatological basis should serve as a condition for representative biblical hermeneutics by comparing John Calvin’s and Pentecostals’ view of the subjective influence of the Spirit, concluding that an ecumenical revisiting of hermeneutics is necessary.

To begin with, there is a conceptual necessity implied in the very concept of cause itself, and in all concepts that have a causal element; and this definitional "must," far from being conventional or arbitrary, reflects the natural necessity of those physical systems which in fact constitute the nature of our universe. The conceptual necessity of the concept of cause can be pointed up in the following way. Assume that we have good reason for saying at to that f, g, (...) h, and i are jointly sufficient to E and hence C of E. What would we say at t1 if f, g, h, and i occurred but not E? We would clearly not say then, or ever, that while ordinarily these conditions are jointly sufficient for E, this time they were not; rather we would say that somehow we were mistaken in thinking that f, g, h, and i at t1 were identical with f, g, h, and i at t0. We might have been mistaken in either of two ways. We might have mis-identified one of the conditions at t1, erroneously thinking, say, that p was an f; or one or more of the conditions might have had its nature altered, losing some capacity or power it once had. In either case, we would withdraw the claim at t1 that C was the cause of E. Since we would withdraw the use of C at t1 and would never admit that f, g, h, and i at any t, if genuine instances of f, g, h, and i, would not produce E, we are clearly using C in such a way that actually producing E is part of its meaning. On the assumption that the conditions are genuinely the same, it follows, so to speak, from the principle of identity that they must produce the same effect. (shrink)

The Church at all times of human existence occupied an important place in the life of society. Under modern conditions, people often feel unprotected, uncertain, and therefore forced to seek support and faith in their happy future. One way of creating a sense of inner peace for a believer is to communicate with God, and the Church acts as an intermediary in this process. Therefore, in our opinion, the Church, as a social institution, is to a large extent responsible for (...) the cultivation of those values ​​which it preaches and which consciously and subconsciously assimilates the citizens. Therefore, we believe that the Church should not be alienated from the problems of society, but, on the contrary, its activities should be oriented towards its modernization and, above all, in the spiritual aspect. For the Ukrainian society in its spiritual life Christian faith was and remains the leading one. In this article, we aim to justify the role of the Christian Churches in shaping the sense of responsibility of our believers. (shrink)

Abū Ḥanīfa (d. 150/767) discussed the main issues of the science of kalām in the first period and expressed his best views on these issues in response to the sects that he accepted as bid'ah (innovation). Later, kalām scholars tried to justify these views by using different arguments according to the changing conditions and time. Undoubtedly, one of the most important opinions that Abū Ḥanīfa expressed and passed on to the next generations from the perspective of the science of kalām (...) is those related to faith. In fact, faith is the strongest and most deep-rooted bond a believer establishes with his/her Creator. The individual shapes his world and the hereafter through this bond. On the other hand, faith is a phenomenon that does not contain doubt but carries certainty. In this respect, a person is included in the same category as a believer after she has firmly believed, and is called a believer or a Muslim, as the Qur'an puts it. Because no matter what race or color he is, he takes the same name because he believes in the same principles. Abū Ḥanīfa, who lived in a time when Muslims differed among themselves and differences of opinion increased, accepted faith as a common denominator by emphasizing the common values of Islam. Abū Ḥanīfa refers to this as "equality in faith". The issue of equality in faith, which is discussed as a result of the differentiation in matters related to the nature of faith, is shaped according to whether the action is counted as part of faith or not. Since Abū Ḥanīfa did not consider deeds a part of faith, so he advocated equality in faith. This view was adopted later by many scholars in the Māturīdī tradition. In the Hanafī-Māturīdī tradition, it can be said that the issue of equality in faith as well as issues such as confirmation and certainty in faith were shaped by the opinions of Abū Ḥanīfa. When equality in faith is accepted, one is not allowed to question the faith of another and say that his/her own faith is superior to the other because only God can know it. On the other hand, the understanding of equality in faith prevents external appearance and formalism from being decisive in one's religious life. Thus, a believer cannot accuse his brother who has deficiencies in his deeds but has faith of being infidel. When Abū Ḥanīfa's view of equality in faith is interpreted according to contemporary paradigms, his emphasis on human love, tolerance, and unity of the ummah, which has validity today, can clearly be observed. Therefore, it is seen that the reflection of a theological issue on social life is stressed in his opinion. This paper aims to study the issue of "equality in faith", one of the issues related to faith, and its reflection on social life by using the texts which are attributed to Abū Ḥanīfa. (shrink)

How do models represent reality? There are two conditions that scientific models must satisfy to be representations of real systems, the aboutness condition and the epistemic condition. In this article, I critically assess the two main fictionalist theories of models as representations, the indirect fiction view and the direct fiction view, with respect to these conditions. And I develop a novel proposal, what I call ‘the new fiction view of models’. On this view, models are akin (...) to fictional stories; they represent real-world phenomena if they stand in a denotation relation with reality; and they enable knowledge of reality via the generation of theoretical hypotheses, model–world comparisons and direct attributions.

This article argues in defence of human–robot friendship. I begin by outlining the standard Aristotelian view of friendship, according to which there are certain necessary conditions which x must meet in order to ‘be a friend’. I explain how the current literature typically uses this Aristotelian view to object to human–robot friendships on theoretical and ethical grounds. Theoretically, a robot cannot be our friend because it cannot meet the requisite necessary conditions for friendship. Ethically, human–robot friendships are wrong (...) because they are deceptive, and could also make it more likely that we will favour ‘perfect’ robots, and disrespect, exploit, or exclude other human beings. To argue against the above position, I begin by outlining and assessing current attempts to reject the theoretical argument—that we cannot befriend robots. I argue that the current attempts are problematic, and do little to support the claim that we can be friends with robots now. I then use the standard Aristotelian view as a touchstone to develop a new degrees-of-friendship view. On my view, it is theoretically possible for humans to have some degree of friendship with social robots now. I explain how my view avoids ethical concerns about human–robot friendships being deceptive, and/or leading to the disrespect, exploitation, or exclusion of other human beings. (shrink)

IntroductionThe meaning of conditional sentences bears an intrinsic relation to a number of central philosophical problems, like the nature of reasoning, the possibility of knowledge, and the status of laws of nature. This has incited philosophers to spend a lot of time working on conditionals and to fill countless bookshelves with inspiring and sophisticated theories on their meaning. However, the overall question of how to approach the meaning of conditionals is still open. There are many different theories on (...) the market, many central issues still need to be solved.But as a topic philosophers are interested in conditionals are special in that they are real; they can be the subject of empirical investigations. And they are actually investigated – in linguistic, in psychology, in the cognitive sciences. The goal of this paper is to illustrate how this ‘external’ information can be used to answer questions on the semantics of conditional sentences that philosophers and logicians are int .. (shrink)

In this paper it is argued that three of the most prominent theories of conditional acceptance face very serious problems. David Lewis' concept of imaging, the Ramsey test and Jonathan Bennett's recent hybrid view all face viscious regresses, or they either employ unanalyzed components or depend upon an implausibly strong version of doxastic voluntarism.
