The primary source of income in the Ottoman Empire, like in other pre-vious and contemporary states, was land. For this reason, the private ownership of land, especially those used for grain production, was avoided, and efforts were made to keep them as state-owned or public lands known as "mirî" or "memleket arazisi". This situation brings up the issue of cultivating the land and generating income from it. The Ottoman Empire further developed the timar system, which was also implemented by the (...) previous states, and allocated land to families based on its productivity by dividing it into certain sizes. These families were required to pay a tax known as "çift resmi", "raiyyet resmi", or "kulluk akçası." The system was based on the cultivation of the land by the peasants, thus ensuring both the production of crops without venturing food security and providing the state with the necessary tax revenue. Thus, it was necessary for the peasants not to abandon their land. One of the precautions taken to ensure this was "cebrî ikamet" (compulsory residency), and the other was "çift bozan resmi" (a tax imposed on those who leave their land uncultivated). Regulations regarding these measures have been included in the Kanunnames (legal codes) since the time of Fatih Sultan Mehmet, and they remained in effect until the 1858 Land Code. Since the nişancıs who prepared the Kanunnames had a good command in Islamic fiqh and the laws were at least theoretically approved by the sheikh al-islam until the mid-17th century, no one among the Ottoman scholars was known to oppose these regulations. Due to the serious disruption of the timar system and the increasing oppression of the peasants, criticisms of the "çift bozan" and "cebrî ikamet" measures began among the scholars in the Damascus region, led by Hayreddin Remlî, in the second half of the 17th century. This criticism intensified over time. In fact, two separate treatises were written on this issue. The scholars in Istanbul were also partly affected by this criticism. In this article, the "çift bozan" tax and its status in Islamic law will be primarily examined. All views in favor or against this issue will be put forth as much as possible, and an evaluation will be made while trying to come up with a different perspective. (shrink)

McKenna’s critique (rather than criticisms) of idealized approaches to epistemology is an important contribution to the literature. In this brief discussion, I set out his main concerns about more idealized approaches, within and beyond social epistemology, before turning to some issues I think he neglects. I suggest that it’s important to pay attention to the prestige hierarchy in philosophy, and to how that hierarchy can serve ideological purposes. The greater prestige of more abstract approaches plays a role in determining what (...) issues and what voices we attend to. (shrink)

Science is the study of our world, as it is in its messy reality. Nonetheless, science requires idealization to function—if we are to attempt to understand the world, we have to find ways to reduce its complexity. Idealization and the Aims of Science shows just how crucial idealization is to science and why it matters. Beginning with the acknowledgment of our status as limited human agents trying to make sense of an exceedingly complex world, Angela Potochnik moves on to explain (...) how science aims to depict and make use of causal patterns—a project that makes essential use of idealization. She offers case studies from a number of branches of science to demonstrate the ubiquity of idealization, shows how causal patterns are used to develop scientific explanations, and describes how the necessarily imperfect connection between science and truth leads to researchers’ values influencing their findings. The resulting book is a tour de force, a synthesis of the study of idealization that also offers countless new insights and avenues for future exploration. (shrink)

Çifte manastırlar, genellikle bir başrahibe tarafından yönetilen ve keşiş-lerle rahibelerin ortak kurallara bağlı olarak yaşadıkları dinî mekanlardır. Bu manastırlarda keşiş ve rahibeler evharistiya ve günlük ibadetler gibi ayinlerde bir araya gelmekte, ancak günün geri kalan zamanlarında kendi bölümlerinde yaşamaktadır. Hıristiyanlığın erken dönemlerinde özellikle Mısır’da ortaya çıkan bu manastırlar, 6. ve 9. yüzyıllar arasında İngiltere, İrlanda ve Fransa’da yaygınlaşmıştır. Bu manastırlar erkek ve kadınların bir arada yaşamaları nedeniyle farklı konsillerle yasaklansa da Ortaçağ’ın geç dönemlerine kadar varlıklarını sürdürmüşlerdir. Konsil kararları ve istilalar (...) nedeniyle artık örneklerine rastlanmasa da İngiltere’de Ortodoks Kilisesine bağlı bir çifte manastır bulunmaktadır. Diğer taraftan günümüzde Hıristiyanlıkta çifte manastırlarda tarihte yaşanan ortak yaşamdan örnekler verilerek yeni bir cinsiyet paradigması oluşturma çalışmaları görülmektedir. Dolayısıyla çifte manastırlar Kilise, kadın ve otorite gibi konuları kapsamı bakımından önemli bir konudur. Çalışmada bu manastırların yapıları, etkileri, problemleri ve tarihsel süreci ele alınmıştır. Makalenin Kilise, kadın, manastır hayatı ve Hıristiyan mistisizmi gibi çalışmalara kaynaklık teşkil etmesi beklenmektedir. (shrink)

Ideal utilitarianism states that the only fundamental requirement of morality is to promote a plurality of intrinsic goods. This paper critically evaluates Hastings Rashdall’s arguments for ideal utilitarianism, while comparing them with G. E. Moore’s arguments. Section I outlines Rashdall’s ethical outlook. Section II considers two different arguments that he provides for its theory of rightness. Section III discusses his defence of a pluralist theory of value. Section IV argues that Rashdall makes a lasting contribution to the defence of ideal (...) utilitarianism. (shrink)

In 2005, Charles Mills published “‘Ideal Theory’ as Ideology” in Hypatia: a withering critique of much of contemporary political philosophy and ethics. For Mills such work in philosophy failed to attend to the realities of social life and politics, and in remaining silent on actual issues of domination and oppression served an ideological role in supporting the interests of white bourgeois men. Around the time that Charles Mills launched his broadside against ideal theory, trans theorists had been fighting their own (...) battle against the abstraction of theory from the realities of trans lives and oppression. Vivian Namaste (2000) and Jay Prosser (1998) argued that contemporary gender theory failed to justice to the actuality of trans life, retreating instead to understanding trans life through literary archetypes and idealized radical figures. In this chapter I’ll compare Mills’ critique of ideal theory with the transfeminist critique of 1990s gender theory, arguing that they share much in common. Centrally, both critiques share an underlying commitment to theory needing to be grounded in the actuality of oppression and power relations. This common thread, I suggest, must continue to guide transfeminist thought and action: contra Marquis Bey (2022) transfeminist thought and praxis must continue to be about trans lives, about the oppression of trans women, and about ways of actually achieving liberation from our current dire position.

Because idealizations frequently advance scientific understanding, many claim that falsehoods play an epistemic role. In this paper, we argue that these positions greatly overstate idealiza...

Robin McKenna argues that we need to make space for an approach to epistemology that avoids the idealizations typical of the field. He applies this approach to topics in applied and social epistemology, such as what to do about science denial, whether we should try to be intellectually autonomous, and what our obligations are to other inquirers.

Many AI systems that make important decisions are black boxes: how they function is opaque even to their developers. This is due to their high complexity and to the fact that they are trained rather than programmed. Efforts to alleviate the opacity of black box systems are typically discussed in terms of transparency, interpretability, and explainability. However, there is little agreement about what these key concepts mean, which makes it difficult to adjudicate the success or promise of opacity alleviation methods. (...) I argue for a unified account of these key concepts that treats the concept of understanding as fundamental. This allows resources from the philosophy of science and the epistemology of understanding to help guide opacity alleviation efforts. A first significant benefit of this understanding account is that it defuses one of the primary, in-principle objections to post hoc explainable AI (XAI) methods. This “rationalization objection” argues that XAI methods provide mere rationalizations rather than genuine explanations. This is because XAI methods involve using a separate “explanation” system to approximate the original black box system. These explanation systems function in a completely different way than the original system, yet XAI methods make inferences about the original system based on the behavior of the explanation system. I argue that, if we conceive of XAI methods as idealized scientific models, this rationalization worry is dissolved. Idealized scientific models misrepresent their target phenomena, yet are capable of providing significant and genuine understanding of their targets. (shrink)

In this paper, I first outline the view developed in my recent book on the role of idealization in scientific understanding. I discuss how this view leads to the recognition of a number of kinds of variability among scientific representations, including variability introduced by the many different aims of scientific projects. I then argue that the role of idealization in securing understanding distances understanding from truth, but that this understanding nonetheless gives rise to scientific knowledge. This discussion will clarify how (...) my view relates to three other recent books on understanding by Henk de Regt, Catherine Elgin, and Kareem Khalifa. (shrink)

Political philosophers frequently claim that political ideals can provide normative guidance for unjust and otherwise nonideal circumstances. This is mistaken. This paper demonstrates that political ideals contribute nothing to our understanding of the normative principles we should satisfy amidst unjust or otherwise nonideal circumstances.

Recent methodological debates regarding the place of feasibility considerations in normative political theory are hindered for want of a rigorous model of the feasibility frontier. To address this shortfall, I present an analysis of feasibility that generalizes the economic concept of a production possibility frontier and then develop a rigorous model of the feasibility frontier using the familiar possible worlds technology. I then show that this model has significant methodological implications for political philosophy. On the Target View, a political ideal (...) presents a long-term goal for morally progressive reform efforts and, thus, serves as an important reference point for our specification of normative political principles. I use the model to show that we can- not reasonably expect that adopting political ideals as long-term reform objectives will guide us toward the realization of morally optimal feasible states of affairs. I conclude by proposing that political philosophers turn their attention to the analysis of actual social failures rather than political ideals. (shrink)

In this paper, I propose that the debate in epistemology concerning the nature and value of understanding can shed light on the role of scientific idealizations in producing scientific understanding. In philosophy of science, the received view seems to be that understanding is a species of knowledge. On this view, understanding is factive just as knowledge is, i.e., if S knows that p, then p is true. Epistemologists, however, distinguish between different kinds of understanding. Among epistemologists, there are those who (...) think that a certain kind of understanding—objectual understanding—is not factive, and those who think that objectual understanding is quasi-factive. Those who think that understanding is not factive argue that scientific idealizations constitute cognitive success, which we then consider as instances of understanding, and yet they are not true. This paper is an attempt to draw lessons from this debate as they pertain to the role of idealizations in producing scientific understanding. I argue that scientific understanding is quasi-factive.

Numerous philosophers allege that the "general theory of second best" (Lipsey and Lancaster, 1956) poses a challenge to the Target View, which asserts that real world reform efforts should aim to establish arrangements that satisfy the constitutive features of ideal just states of affairs. I demonstrate two claims that are relevant in this context. First, I show that the theory of second best fails to present a compelling challenge to the Target View in general. But, second, the theory of second (...) best requires ideal theorists to undertake certain kinds of causal and comparative analyses that are typically thought to lie beyond the borders of conventional ideal theory.

When we admire a person, we don’t just have a wow-response towards them, as we might towards a painting or a sunset. Rather, we construe them as realizing an ideal of the person in their lives to a conspicuous degree. To merit admiration, it is not enough simply to do something valuable or to possess desirable character traits. Rather, one’s achievements must manifest commitments and character traits that define a worthwhile ideal. Agential admiration, I argue, is a person-focused attitude like (...) shame, contempt, and hubristic pride, not an act-focused one like gratitude or guilt, not to mention mere evaluation as excellent. Given its holistic focus, its motivational effects permeate our interactions with its target, who is construed as an exemplar. Consequently, even if someone is admirable in some way, admiring them may be all-things-considered inappropriate, if they fall short of other ideals that we ought to care about. (shrink)

Eva Erman and Niklas Möller have recently presented a trenchant critique of my (2015) argument that ideal normative theories are uninformative for certain practical purposes. Their criticisms are largely correct. In this note, I develop the ideas behind my earlier argument in a way that circumvents their critique and explains more clearly why ideal theory is uninformative for certain purposes while leaving open the possibility that it might be informative for other purposes.

In this paper we present a new framework of idealization in biology. We characterize idealizations as a network of counterfactual conditionals that can exhibit different degrees of contingency. We use the idea of possible worlds to say that, in departing more or less from the actual world, idealizations can serve numerous epistemic, methodological or heuristic purposes within scientific research. We defend that, in part, it is this structure what helps explain why idealizations, despite being deformations of reality, are so successful (...) in scientific practice. (shrink)

This book argues that the major traditions in the philosophy of language have mistakenly focused on highly idealized linguistic contexts. Instead, it presents a non-ideal foundational theory of language that contends that the essential function of language is to direct attention for the purpose of achieving diverse social and political goals. Philosophers of language have focused primarily on highly idealized linguistic contexts in which cooperative agents are working toward the shared goal of gaining information about the world. This approach abstracts (...) away from important issues like power, ideology, social position, and diversity of goals which are crucial to explaining linguistic phenomena both at the semantic and pragmatic levels. This book begins by examining the work of some of the pioneers of this tradition--primarily David Lewis, Paul Grice, and Robert Stalnaker. The author shows that various problems have their source in idealizations made at the foundational level of linguistic theory and proposes to rebuild from the ground-up. She presents a non-ideal foundational theory of language which retains the major insights of traditional frameworks while rejecting the social idealizations that guide them. Then, she explores the social and political applications of her account to issues such as dog whistling, propaganda, slurs and racist speech, silencing, and manipulation. Non-Ideal Foundations of Language will appeal to researchers and advanced students in philosophy of language who are interested in the social and political applications of language, as well as traditional metasemantic theory.

In this paper, I first argue against various attempts to justify idealizations in scientific models that explain by showing that they are harmless and isolable distortions of irrelevant features. In response, I propose a view in which idealized models are characterized as providing holistically distorted representations of their target system. I then suggest an alternative way that idealized modeling can be justified by appealing to universality.

In a possible world framework, an agent can be said to know a proposition just in case the proposition is true at all worlds that are epistemically possible for the agent. Roughly, a world is epistemically possible for an agent just in case the world is not ruled out by anything the agent knows. If a proposition is true at some epistemically possible world for an agent, the proposition is epistemically possible for the agent. If a proposition is true at (...) all epistemically possible worlds for an agent, the proposition is epistemically necessary for the agent, and as such, the agent knows the proposition. -/- This framework presupposes an underlying space of worlds that we can call epistemic space. Traditionally, worlds in epistemic space are identified with possible worlds, where possible worlds are the kinds of entities that at least verify all logical truths. If so, given that epistemic space consists solely of possible worlds, it follows that any world that may remain epistemically possible for an agent verifies all logical truths. As a result, all logical truths are epistemically necessary for any agent, and the corresponding framework only allows us to model logically omniscient agents. This is a well-known consequence of the standard possible world framework, and it is generally taken to imply that the framework cannot be used to model non-ideal agents that fall short of logical omniscience. -/- A familiar attempt to model non-ideal agents within a broadly world involving framework centers around the use of impossible worlds where the truths of logic can be false. As we shall see, if we admit impossible worlds where “anything goes” in epistemic space, it is easy to avoid logical omniscience. If any logical falsehood is true at some impossible world, then any logical falsehood may remain epistemically possible for some agent. As a result, we can use an impossible world involving framework to model extremely non-ideal agents that do not know any logical truths. -/- A much harder, and considerably less investigated challenge is to ensure that the resulting epistemic space can also be used to model moderately ideal agents that are not logically omniscient but nevertheless logically competent. Intuitively, while such agents may fail to rule out impossible worlds that verify complex logical falsehoods, they are nevertheless able to rule out impossible worlds that verify obvious logical falsehoods. To model such agents, we need a construction of a non-trivial epistemic space that partly consists of impossible worlds where not "anything goes". This involves imposing substantive constraints on impossible worlds to eliminate from epistemic space, say, trivially impossible worlds that verify obvious logical falsehoods. -/- The central aim of this dissertation is to investigate the nature of such non-trivially impossible worlds and the corresponding epistemic spaces. To flag my conclusions, I argue that successful constructions of epistemic spaces that can safely navigate between the Charybdis of logical omniscience and the Scylla of of “anything goes” are hard, if not impossible to find.

Based on three recently published books on climate justice, this article reviews the field of climate ethics in light of developments of international climate politics. The central problem addressed is how idealised normative theories can be relevant to the political process of negotiating a just distribution of the costs and benefits of mitigating climate change. I distinguish three possible responses, that is, three kinds of non-ideal theories of climate justice: focused on (1) the injustice of some agents not doing their (...) part; (2) the policy process and aiming to be realistic; and (3) grievances related to the transition to a clean-energy economy. The methodological discussion underpinning each response is innovative and should be of interest more generally, even though it is still underdeveloped. The practical upshot, however, is unclear: even non-ideal climate justice may be too disconnected from the fast-moving and messy climate circus. (shrink)

Does rationality require logical omniscience? Our best formal theories of rationality imply that it does, but our ordinary evaluations of rationality seem to suggest otherwise. This paper aims to resolve the tension by arguing that our ordinary evaluations of rationality are not only consistent with the thesis that rationality requires logical omniscience, but also provide a compelling rationale for accepting this thesis in the first place. This paper also defends an account of apriori justification for logical beliefs that is designed (...) to explain the rational requirement of logical omniscience. On this account, apriori justification for beliefs about logic has its source in logical facts, rather than psychological facts about experience, reasoning, or understanding. This account has important consequences for the epistemic role of experience in the logical domain. In a slogan, the epistemic role of experience in the apriori domain is not a justifying role, but rather an enabling and disabling role. (shrink)

We define in precise terms the basic properties that an ‘ideal propositional paraconsistent logic’ is expected to have, and investigate the relations between them. This leads to a precise characterization of ideal propositional paraconsistent logics. We show that every three-valued paraconsistent logic which is contained in classical logic, and has a proper implication connective, is ideal. Then we show that for every n > 2 there exists an extensive family of ideal n -valued logics, each one of which is not (...) equivalent to any k -valued logic with k < n. (shrink)

In her ‘On the apparent paradox of ideal theory’, Laura Valentini combines three supposedly plausible premises to derive the paradoxical result that ideal theory is both unable to, and indispensable for, guiding action. Her strategy is to undermine one of the three premises by arguing that there are good and bad kinds of ideal theory, and only the bad kinds are vulnerable to the strongest version of their opponents’ attack. By undermining one of the three premises she releases ideal theorists (...) from the paradox, which is as follows. (1) Any sound theory of justice is action-guiding. (2) Any sound theory of justice is ideal. (3) Any ideal theory fails to be action-guiding. Here I shall respond to Valentini in two ways. First, I shall show that both (1) and (2) are false. The falsity of either is sufficient to release ideal theorists from the paradox. Second, I shall show that Valentini’s response to (3) can be extended, because her bad kinds of ideal theory do not necessarily fail to guide action. The cumulative effect of my arguments further strengthens Valentini’s support of ideal theory. I will deal with premises (1) and (2) in Sections I and II, and (3) in Section III. (shrink)

Idealization and abstraction are central concepts in the philosophy of science and in science itself. My goal in this paper is suggest an account of these concepts, building on and refining an existing view due to Jones Idealization XII: correcting the model. Idealization and abstraction in the sciences, vol 86. Rodopi, Amsterdam, pp 173–217, 2005) and Godfrey-Smith Mapping the future of biology: evolving concepts and theories. Springer, Berlin, 2009). On this line of thought, abstraction—which I call, for reasons to be (...) explained, abstractness—involves the omission of detail, whereas idealization consists in a deliberate mismatch between a description and the world. I will suggest that while the core idea underlying these authors’ view is correct, they make several assumptions and stipulations that are best avoided. For one thing, they tie abstractness too close to truth. For another, they do not allow sufficient room to the difference between idealization and error. Taking these points into account leads to a refined account of the distinction, in which abstractness is seen in terms of relative richness of detail, and idealization is seen as closely connected with the knowledge and intentions of idealizers. I lay out these accounts in turn, and then discuss the relationship between the two concepts, and several other upshots of the present way of construing the distinction. (shrink)

A number of social theorists have contended that the essence of historical analysis is the employment of ideal types to comprehend past goings-on. But, while acknowledging that the study of history through ideal types can yield genuine insight, we may still ask if it represents the full emancipation of historical understanding from other modes of conceiving the past. This paper follows Michael Oakeshott's work on the philosophy of history in arguing that explaining the historical past by means of ideal types, (...) even though offering a coherent and fruitful enterprise, nevertheless falls short of fully embodying the characteristics that differentiate historical understanding. -/- This dispute involves fundamental issues regarding the nature of the social sciences. Furthermore, I suggest that it is of more than purely theoretical interest, in that social theorists who have accepted the Weberian view of historical inquiry will tend to be unaware of the defects inherent in all attempts to capture the nature of past events in a net of generalizations, and thus may be lead to ignore the inherent partiality of the understanding of historical happenings provided by ideal typification.

Many criticisms of epistemic logic have centered around its use of devices such as idealized knowers with logical omniscience and perfect self-knowledge. One possible response to such criticisms is to say that these idealizations are normative devices, and that epistemic logic tells us how agents ought to behave. This paper will take a different approach, treating epistemic logic as descriptive, and drawing the analogy between its formal models and idealized scientific models on that basis. Treating it as descriptive matches the (...) way in which some philosophers, including one of its founders, Jaako Hintikka, have thought about epistemic logic early in its history. Further, the analogy between the two fields will give us a way to defuse criticisms that see epistemic logic as unrealistic. For example, criticizing models of epistemic logic in which agents know all propositional tautologies as being unrealistic would be like criticizing frictionless planes in physics for being unrealistic. Each one would certainly be an unsuitable model for studying some kinds of phenomena, but is entirely appropriate for others. After outlining the analogy between epistemic and scientific models, we will discuss some ways in which idealizations are used by different research programs in epistemic logic. (shrink)

Ideal epistemologists investigate the nature of pure epistemic rationality, abstracting away from human cognitive limitations. Non-ideal epistemologists investigate epistemic norms that are satisfiable by most humans, most of the time. Ideal epistemology faces a number of challenges, aimed at both its substantive commitments and its philosophical worth. This paper explains the relation between ideal and non-ideal epistemology, with the aim of justifying ideal epistemology. Its approach is meta-epistemological, focusing on the meaning and purpose of epistemic evaluations. I provide an account (...) on which the fundamental difference between ideal and non-ideal epistemic evaluations is that only the non-ideal epistemic ‘ought’ implies any substantive ‘can’. I argue that only ideal epistemic evaluations are ‘normatively robust’: they are neither conventional nor seriously context-sensitive. Non-ideal epistemic evaluations are normatively non-robust, exhibiting both conventionality and serious context-sensitivity from an interesting variety of distinct sources. For this reason, non-ideal epistemic evaluations won’t characterize the fundamental nature of epistemic rationality. Non-ideal epistemic rationality depends, not merely on what’s epistemically valuable, but also on modally contingent epistemic conventions and contextually contingent constraints on epistemic options. If we want a normatively robust theory of epistemic rationality, ideal epistemology is the only game in town. (shrink)

Rawls’s contractualist approach to justice is well known for its adoption of ideal theory. This approach starts by setting out the political goal or ideal and leaves it to non-ideal or partial compliance theory to map out how to get there. However, Rawls’s use of ideal theory has been criticized by Sen from the right and by Mouffe from the left. We critically address these concerns in the context of developing a Rawlsian approach to climate justice. While the importance of (...) non-ideal theory for climate justice is increasingly being understood, its strategic and institutional importance for a Rawlsian approach needs further elaboration. We focus on the role of the Kantian conception of the reasonable and rational powers of persons in Rawls’s work and show how this helps us to develop a partial compliance theory that focuses on the importance of institutions and strategic political action for achieving climate justice.

In discussions surrounding epistemology and rationality, it is often useful to assume an agent is rational or ideally rational. Often, this ideal rationality assumption is spelled out along the following lines: -/- 1. The agent believes everything about a situation which the evidence entitles her to believe and nothing which it does not. -/- 2. The agent believes all the logical consequences of any of her beliefs. -/- 3. The agent knows her own mind: if she believes P, she believes (...) that she believes P; and if she doesn't believe P, she believes that she doesn't believe P. -/- 4. The agent believes nothing of the form 'P and it is not the case that P.' -/- 5. If an agent's background belief-set satisfies 1-4 and if rationality requires the agent to add P to her belief-set, then the resulting belief-set will also satisfy 1-4. -/- While individually plausible, there are cases in which holding on to 1-5 generates paradox. Some resolve such paradoxical cases by granting 1-5 but arguing while ideally rational agents can exist, they can't possibly ever find themselves in such a situation: such case descriptions are epistemically incoherent. Others allow that rational agents can coherently find themselves in such odd circumstances, and argue that it's more reasonable to weaken our concept of ideal rationality and give up premise (2) above. However, this strategy has also been rejected. My aim in this paper is to defend the utility of positing an ideally rational agent in such paradoxical circumstances. I argue in such cases we should give up (2), in particular the assumption that (necessarily) if an ideally rational agent believes both P and the conditional, if P then Q, then she believes Q.. What's important is to hold on to the goal of positing ideal rationality: to maximize the amount of true or probably true information a thinker can justifiably believe in a given circumstance. Normally that will mean holding on to (2), but these unusual paradoxical cases are best handled by giving up (2). (shrink)

The book reveals different dimensions of modeling in the historical sciences. Papers collected in the first part (Ontology of the Historical Process) consider different models of historical reality and discuss their status. The second part (Modeling in the Methodology of History) presents various forms of idealization in historiographic research. The papers in the third part (Modeling in the Research Practice) present various models of past reality (e.g. of Poland, Central Europe and the general history of the feudal system) put forward (...) by historians. Other papers consider the status of scientific laws and historical generalizations. The volume will be of interest to those who study analytical philosophy of history, methodology of history and social sciences, social philosophy as well as theory and history of historiography.

It argues that the continuum idealizations are explanatorily ineliminable and that a full understanding of certain physical phenomena cannot be obtained (...) through completely detailed, non-idealized representations.

What are appropriate criteria for assessing a theory of morality? In Ideal Code, Real World, Brad Hooker begins by answering this question, and then argues for a rule-consequentialist theory. According to rule-consequentialism, acts should be assessed morally in terms of impartially justified rules, and rules are impartially justified if and only if the expected overall value of their general internalization is at least as great as for any alternative rules. In the course of developing his rule-consequentialism, Hooker discusses impartiality, well-being, (...) fairness, equality, the question of how the 'general internalization' of rules is to be interpreted by rule-consequentialism, and the main objections to rule-consequentialism. He also discusses the social contract theory of morality, act-consequentialism, and the question of which moral prohibitions and which duties to help others rule-consequentialism endorses. The last part of the book considers the implications of rule-consequentialism for some current controversies in practical ethics. (shrink)

What is it to have and act on a personal ideal? Someone who aspires to be a philosopher might imaginatively think “I am a philosopher” by way of motivating herself to think hard about a philosophical question. But doing so seems to require her to act on an inaccurate self-description, given that she isn’t yet what she regards herself as being. J. David Velleman develops the thought that action-by-ideal involves a kind of fictional self-conception. My aim is to expand our (...) thinking about personal ideals by developing another way of understanding them. On this view action-by-ideal involves a kind of metaphorical self-conception. I investigate some salient differences between these views with the aim of understanding the different perspectives they take on the rationality of action-by-ideal. Where the fiction view runs into problems of literary coherence, the metaphor view exploits the richness of poetic invention. But action-by-ideal is a complex phenomenon about which there may be no tidy story to be told. This paper is an attempt to clarify and understand more of this messy terrain. (shrink)

In this paper we inquire into the fundamental assumptions that underpin the ideal of the Bio-Based Economy as it is currently developed . By interpreting the BBE from the philosophical perspective on economy developed by Georges Bataille, we demonstrate how the BBE is fully premised on a thinking of scarcity. As a result, the BBE exclusively frames economic problems in terms of efficient production, endeavoring to exclude a thinking of abundance and wastefulness. Our hypothesis is that this not only entails (...) a number of internal tensions and inconsistencies with regard to the ideal of BBE, but ultimately undermines the ideal itself, by pushing purported regenerativity into a cataclysmic and terminal discharge. We here point to the strategies that the BBE employs in this exclusion, the fundamental assumptions regarding the relation between energy and economy that underpin this endeavor, as well as to the resulting inconsistencies and their catastrophic consequences. We finally argue for the introduction of the presently excluded question of abundance and wastefulness and explore the implications of such a question for the ideal of a zero-waste humanity.

I argue that advocates of moderate epistemic idealization need some standards against which they can determine whether a particular individual P has a responsibility to acquire some specific piece of information α. Such a specification is necessary for the purpose of determining whether a reason R, the recognition of which depends on accounting for α, can legitimately be ascribed to P. To this end, I propose an initial sketch of a criterion that may be helpful in illuminating the conditions in (...) which P might be said to have a responsibility to take α into account when searching for reasons to act or believe. I worry that reason ascriptions that are based on information acquisition expectations which are not captured by this criterion may be open to charges of authoritarianism, especially when such a reason ascription prompts one person to demand that another act in a way that is responsive to the ascribed reason.

Recently, there has been growing interest in methodological issues of non-ideal theoretical philosophy. While some explicitly commit to non-ideal theorising, others doubt that there is anything useful about the ideal/non-ideal distinction in theoretical philosophy. The aim of this paper is twofold. On the one hand, I propose a way of doing non-ideal theoretical philosophy, once we realise how limited certain idealised projects are. Since there is a big overlap between projects that are called non-ideal and applied, the second aim is (...) to distinguish between these categories in order to show that applied theoretical philosophy is only worth pursuing if it operates in a non-ideal framework. I argue that we should be pluralistic about possible non-ideal theories and view the ideal/non-ideal differences as a matter of degree, rather than kind. As an example, I show how my version of non-ideal theory is useful to a concrete debate in philosophy of language. My proposal allows us to identify already existing non-ideal approaches to linguistic meaning and encourages us to further engage in the debate on non-ideal theoretical philosophy. (shrink)

Every model leaves out or distorts some factors that are causally connected to its target phenomenon -- the phenomenon that it seeks to predict or explain. If we want to make predictions, and we want to base decisions on those predictions, what is it safe to omit or to simplify, and what ought a causal model to describe fully and correctly? A schematic answer: the factors that matter are those that make a difference to the target phenomenon. There are several (...) ways to understand differencemaking. This paper advances a view as to which is the most relevant to the forecaster and the decision-maker. It turns out that the right notion of differencemaking for thinking about idealization in prediction is also the right notion for thinking about idealization in explanation; this suggests a carefully circumscribed version of Hempel's famous thesis that there is a symmetry between explanation and prediction.

Implicit in feminist and other critiques of ideal theorizing is a particular view of what normative theory should be like. Although I agree with the rejection of ideal theorizing that oppression theorists (and other theorists of justice) have advocated, the proposed alternative of nonideal theorizing is also problematic. Nonideal theorizing permits one to address oppression by first describing (nonideal) oppressive conditions, and then prescribing the best action that is possible or feasible given the conditions. Borrowing an insight from the "moral (...) dilemmas debate"— namely that moral wrongdoing or failure can be unavoidable—I suggest that offering (only) action-guidance under non-ideal conditions obscures the presence and significance of unavoidable moral failure. An adequate normative theory should be able to issue a further, non-action-guiding evaluative chim, namely that the best that is possible under oppressive conditions is not good enough, and may constitute a moral failure. I find exclusively action-guiding nonideal theory to be both insufficiently nonidealizing (because it idealizes the moral agent by falsely characterizing the agent as always able to avoid moral wrongdoing) and meanwhile too strongly adapted to the nonideal (because normative expectations are lowered and detrimentally adapted to options that, while the best possible, are still unacceptable).

In lieu of an abstract, here is a brief excerpt of the content:The Ideal of Shared Decision Making Between Physicians and PatientsDan W. Brock (bio)IntroductionShared treatment decision making, with its division of labor between physician and patient, is a common ideal in medical ethics for the physician-patient relationship.1 Most simply put, the physician's role is to use his or her training, knowledge, and experience to provide the patient with facts about the diagnosis and about the prognoses without treatment and with (...) alternative treatments. The patient's role in this division of labor is to provide the values—his or her own conception of the good—with which to evaluate these alternatives, and to select the one that is best for himself or herself. As a rough guide to practice, this is a reasonable conception; most of the time it is likely to produce sound treatment decisions. However, as an ideal it is too simplistic, and is subject to several challenges that I will explore in this paper.Some challenges relate to the physician's role. This facts/values division of labor seems to assume that the physician can and should provide the facts about treatment alternatives in a value-neutral form. But some have questioned whether the sciences on which medicine is based are, or can be, value free. Moreover, the concepts of health and disease, and of the normal and pathological, are held by many to be value laden. And even if it is possible for physicians to provide only value-neutral facts to the patient, should the physicians' role be restricted in this way?Other challenges that I will present in the paper are to the patient's role [End Page 28] as provider of the values for the evaluation of the different treatment alternatives. One defense of this role is based on the claim that physicians are not in a position to know reliably what is in a patient's best interests (Buchanan, forthcoming). I believe at least as influential—even if often not explicitly stated—is an extreme subjectivism about values that assumes that the patient's own ultimate values, which define his or her own conception of the good, are incorrigible. By incorrigible, I mean they cannot be mistaken. In the standard case in which treatment is pursued for the patient's benefit, this extreme subjectivism is thought to support the patient's values guiding treatment decision making and treatment. I will explore this incorrigibility claim and will argue that on each of the main philosophical conceptions of the good for persons it is indefensible and should not be the basis for shared treatment decision making.Underlying this view of the physician-patient division of labor are assumptions and beliefs about the nature and relation of facts and values, and science and ethics, that are largely the legacy of a logical positivism that has long since been rejected by most philosophers. It is time that these unstable foundations for our normative ideal of the physician-patient relation were finally removed and replaced with more defensible underpinnings.Two Models of the Physician-Patient RelationshipPositivists insisted on a relatively sharp distinction between descriptive or empirical claims and science, on the one hand, and evaluative claims and ethics, on the other.2 Descriptive statements and the claims of science were to be true or false according to whether they in fact correctly described and explained the world. By remaining properly descriptive or empirical, science could, at least in principle, be entirely value neutral or value free.In its more extreme versions, positivism held that ethical judgments lacked cognitive content, but were instead expressions of emotions or attitudes, and as such could be neither true nor false, correct or mistaken. Because no evaluative statements were held to be logically entailed by any descriptive or empirical statements, moral reasoning was thought to be properly understood not as reasoning but as attempts at nonrational persuasion.3 Many drew from this an extreme subjectivism in ethics along the lines of what I have called above the incorrigibility thesis—there is no meaningful sense in which an individual's ultimate values defining his or her own conception of the good life could be mistaken, false, or unfounded.These...
