The theoretical virtue of parsimony values the minimizing of theoretical commitments, but theoretical commitments come in two kinds : ontological and ideological. While the ontological commitments of a theory are the entities it posits, a theory’s ideological commitments are the primitive concepts it employs. Here, I show how we can extend the distinction between quantitative and qualitative parsimony, commonly drawn regarding ontological commitments, to the domain of ideological commitments. I then argue that qualitative ideological (...) parsimony is a theoretical virtue. My defense proceeds by demonstrating the merits of qualitative ideological parsimony and by showing how the qualitative conception of ideological parsimony undermines two notable arguments from ideological parsimony: David Lewis’ defense of modal realism and Ted Sider’s defense of mereological nihilism.

Many metaphysicians utilize the virtue‐driven methodology. According to this methodology, one theory is more worthy of endorsement than another insofar as it is more virtuous. In this paper, I show how a theory's overall virtue is shaped by its ideological parsimony – parsimony with respect to the terminology employed in stating the theory. I distinguish between a theory's truth and its fidelity (‘joint‐carvingness’) and the corresponding epistemic and fidelic virtues. I argue that ideological parsimony is (...) not an epistemic virtue but is a fidelic virtue. Insofar as metaphysicians value fidelity, then, ideological parsimony has an important role in theory choice. (shrink)

Quine taught us the difference between a theory’s ontology and its ideology. Ontology is the things a theory’s quantifiers must range over if it is true, Ideology is the primitive concepts that must be used to state the theory. This allows us to split the theoretical virtue of parsimony into two kinds: ontological parsimony and ideological parsimony. My goal is help illuminate the virtue of ideological parsimony by giving a criterion for ideological innocence—a (...) rule for when additional ideology does not count against parsimony. I propose the expressive power innocence criterion: if the ideology of theory one is expressively equivalent to that of theory two, then neither is ideologically simpler than the other. In its favor I offer the argument from accuracy, showing that any account of a theoretical virtue that is supposed to make theories that have it more likely to be true than theories that do not must respect it. Next I consider its ramifications, eliminating rival views and passing judgment on some arguments from parsimony that can be found in the literature. Finally, I consider two objections. First: I address an objection arising from the possibility of languages with a ‘primitive’ operator that allows us to list a theory’s primitives in the object-language. Second: I address an objection raised by Nelson Goodman against attempts to reckon simplicity by expressive power. Both objections fail. (shrink)

According to qualitativism, thisness is not a fundamental feature of reality; facts about particular things are metaphysically second-rate. In this paper, I advance an argument for qualitativism from ideological parsimony. Supposing that reality fundamentally contains an array of propertied things, non-qualitativists employ a distinct name (or constant) for each fundamental thing. I argue that these names encode a type of worldly structure (thisness structure) that offends against parsimony and that qualitativists can eliminate without incurring a comparable (...) class='Hi'>parsimony-offense. (shrink)

Many metaphysicians often appeal to Hume’s dictum (HD), according to which there are no necessary connections between distinct entities (or states of entities), in order to resist theories that commit us to such connections. Some have argued that HD is an unsupported dogma of metaphysics. But theories that commit us to necessary connections between distinct goings-on can also be resisted by invoking a normative twist on HD, which I call the Humean Solvent (HS): “Do not connect distinct entities (or states (...) of entities) beyond necessity”. HS is a principle of structural parsimony – assuming that a theory is structurally more parsimonious than another when the latter is committed to a more connected ontology than the former is. Just as Ockham’s ‘razor’ encourages us to cut down superfluous ontological commitments, the Humean ‘solvent’ encourages us to dissolve dispensable metaphysical glue: we ought not to glue elements of our ontology beyond necessity. HS has both a qualitative and a quantitative dimension: qualitatively, it encourages us to avoid using metaphysical glues that are unnecessarily strong, the strongest of which being metaphysically necessary connections; quantitatively, it encourages us not to metaphysically glue things that need no gluing. Thus, given HS, other things being equal, what is worst is a theory that entails that everything is metaphysically necessarily connected to anything else and what is best is a theory that leaves all things loose and separable. In this paper, I will first compare HD and HS as grounds for paradigmatic Humean doctrines in contemporary metaphysics, then I will argue that structural parsimony is neither a variety of ontological nor of ideological parsimony; finally, I will offer an argument for HS.

In this paper, I develop a novel account of ideological kinds. I first present some conceptual territory regarding the use of Occam’s Razor in minimizing ontological commitments. I then present the analogous device for minimizing ideological commitments, what I call the Comb. I argue that metaphysicians ought to use both or none at all. This means that those who endorse a principle of ontological parsimony ought to also endorse some principle of ideological parsimony, where we (...) ought to prefer the metaphysical theory that employs less ideology. In support of one such principle, I propose a novel account of ideological kinds. I individuate ideological kinds based on the satisfaction of two conditions: interdefinability and sameness of syntactic category. Ultimately, I think this account is the best available. It does, however, produce surprising results. For instance, my account shows that quantifier pluralism is ideologically parsimonious. I end by replying to some objections. (shrink)

What is the point of ideology critique? Prominent Anglo-American philosophers recently proposed novel arguments for the view that ideology critique is moral critique, and ideologies are flawed insofar as they contribute to injustice or oppression. We criticize that view and make the case for an alternative and more empirically-oriented approach, grounded in epistemic rather than moral commitments. We make two related claims: (i) ideology critique can debunk beliefs and practices by uncovering how, empirically, they are produced by self-justifying power, and (...) (ii) the self-justification of power should be understood as an epistemic rather than moral flaw. Drawing on the recent realist revival in political theory, we argue that this genealogical approach has more radical potential, despite being more parsimonious than morality-based approaches. We demonstrate the relative advantages of our view by discussing the results of empirical studies on the contemporary phenomenon of neopatriarchy in the Middle East and North Africa. (shrink)

In this paper, I argue for the instability of an increasingly popular position about how metaphysicians ought to regard parsimony. This instability is rooted in an unrecognized tension between two claims. First, we as metaphysicians ought to minimize the number of ontological kinds we posit. Second, it is not the case that we ought to minimize the number of ideological expressions we employ, especially when those expressions are of the same ideological kind (e.g. the compositional predicates "is (...) a part of" and "overlaps"). I argue that the two claims are in tension with one other. At the very least, minimizing the number of ontological kinds posited entails minimizing the number of expressions employed---more specifically, the "ontologically committing" predicates. But, plausibly, the tension runs deeper than that. I suggest that minimizing the number of ontological kinds just is a specific way of minimizing the number of ideological expressions employed in stating a theory. The two activities target the same aspect of reality, the world's metaphysical structure. I end by evaluating three different responses to this puzzle. Ultimately, I suggest that metaphysicians should treat the minimization of the number of ideological expressions as more important than it currently is treated. (shrink)

Indispensability-based arguments for mathematical platonism are typically motivated by drawing an analogy between abstract mathematical objects and concrete scientific posits. In this paper, I argue that mathematics can sometimes help to reduce our concrete ontological, ideological, and structural commitments. My focus is on optimization explanations, and in particular the case study involving periodical cicadas. I argue that in this case, stronger mathematical apparatus yields explanations that have fewer concrete commitments. The nominalist cannot accept these more parsimonious explanations without embracing (...) the stronger mathematics, and this poses a challenge for the nominalist position. (shrink)

Most of the theories of location on the market appear to be ideologically parsimonious at least in the sense that they take as primitive just one locative notion and define all the other locative notions in terms of it. Recently, however, the possibility of some exotic metaphysical scenarios involving gunky mixtures and extended simple regions of space has been argued to pose a significant threat to parsimonious theories of locations. The aim of this paper is to show that a theory (...) taking as primitive a notion of plural pervasive location and allowing for irreducibly plural locative facts can account for all the putatively problematic scenarios for parsimonious theories of location. Furthermore, I will also argue that the notion of plural pervasive location is compatible with the possibility of multilocation. (shrink)

In this paper, I defend modal dimensionalism against the objection that it is ontologically and ideologically heavy. First, I briefly outline the theory and the objection against it. The objection relies on the widely accepted view that ontological and ideological parsimony are operational criteria when comparing metaphysical theories. Second, I outline the conventional distinction between ontology and ideology in the metaphysical tradition. Third, I challenge a particular kind of parsimony: reduction by identification. Fourth, even if reduction by (...) identification is accepted, I show that theories that pursue this often minimize differences, and that such minimization paves the way to epistemic underdetermination. Finally, I demonstrate that some theories in modal metaphysics also suffer from difference minimization and should thus not be measured on the ontology/ideology scale. (shrink)

Some truthmaker theorists posit a distinctive kind of entity to solve the problem of providing ontological grounding for negative truths. Recently, A. M. Griffith has raised a general objection against these alleged truthmakers based on an explanatory constraint on truthmaking and the existence condition of these entities. This paper counters the objection by placing it on the horns of a dilemma: the argument must either specify that the existence condition in question is a conceptual matter or insist that the condition (...) is of properly metaphysical substance. I first argue that the former horn cannot be pursued because it makes the objection irrelevant to the alleged claims of truthmaking. I then argue that the latter horn is also highly problematic because simply insisting on the claim begs the question; appreciating this point leads proponents and opponents of the alleged truthmakers to a substantial debate about the metaphysical nature of these entities and the overall theoretical benefit of their postulation. The discussion shows that Griffith's argument fails to establish its conclusion and reveals what is actually required to argue for/against a particular proposal to provide ontological grounding for negative truths.

Some facts ground by generating: they ground by bringing about other facts or grounding connections among them. Intuitively, other facts play a similar role to background conditions in the causal case: they ground by enabling the obtaining of grounded facts or generative connections among them. As we may ask whether causal background conditions are irreducible to causes, we may wonder whether enablers are irreducible to generators. Some metaphysicians defend a genuine metaphysical distinction between generators and enablers. Yet considerations from (...) class='Hi'>ideological parsimony and unity should prompt us to defend a unified account of ground. Here, I identify and discuss some characteristics extracted from the literature that are said to be possessed by enablers only. Contrary to this claim, I argue that generators can possess the same features. I conclude that such features should not be regarded as a guide to the irreducibility of enabling to generation.

Names name, but there are no individuals who are named by names. This is the key to an elegant and ideologically parsimonious strategy for analyzing the Buddhist catuṣkoṭi. The strategy is ideologically parsimonious, because it appeals to no analytic resources beyond those of standard predicate logic. The strategy is elegant, because it is, in effect, an application of Bertrand Russell's theory of definite descriptions to Buddhist contexts. The strategy imposes some minor adjustments upon Russell's theory. Attention to familiar catuṣkoṭi from (...) Vacchagotta and Nagarjuna as well as more obscure catuṣkoṭi from Khema, Zhi Yi, and Fa Zang motivates the adjustments. The result is a principled structural distinction between affirmative and negative catuṣkoṭi, as well as analyses for each that compare favorably to more recent efforts from Tillemans, Westerhoff, and Priest.

Most theorists treat the ‘relation’ of identity as being more fundamental (or basic) than the ‘relation’ of (numerical) difference. Herbert Hochberg suggests, instead, that difference is to be treated as basic. My goal in this paper is to answer two related questions. First, what is it for a theorist to treat difference or identity as basic? Second, which of these two ‘relations’ is to be treated as basic? I begin by outlining four reasons that one might be motivated to endorse (...) the view that difference is to be treated as basic. Based on these reasons, I distinguish three ways of conceiving of what is involved in treating difference as basic: one conception involves the reification of the relation of difference, whereas the other two do not. Finally, I consider the theoretical consequences, particularly as concerns ontological parsimony, of treating difference as basic in these ways. My ultimate position is that there is a sense in which the second question from above is wrongheaded: difference and identity are, so to speak, features of the same ‘ideological apparatus’ (namely, that of quantification), so there is no real decision to be made about which to treat as basic. If this is correct, then the consequences for a theory's ontological parsimony that result from treating difference, identity, or both as basic are just the same as those that issue from the employment of quantification within a theory – namely, one's theory thereby incurs an ontological commitment to things.

Primitives are both important and unavoidable, and which set of primitives we endorse will greatly shape our theories and how those theories provide solutions to the problems that we take to be important. After introducing the notion of a primitive posit, I discuss the different kinds of primitives that we might posit. Following Cowling (2013), I distinguish between ontological and ideological primitives, and, following Benovsky (2013) between functional and content views of primitives. I then propose that these two distinctions (...) cut across each other leading to four types of primitive posits. I then argue that theoretical virtues should be taken to be meta-theoretical ideological primitives. I close with some reflections on the global nature of comparing sets of primitives. (shrink)

On 30 June 2021, Ohio state Governor, Mike DeWine, signed a Bill which would enact the state's budget for the next two years. In addition to its core funding imperatives, the Bill also contained an amendment significantly expanding entitlements of health care providers to conscientiously object to professional duties to provide controversial health care services. This amendment has been heavily criticised as providing the means to allow health care providers to discriminate against a wide range of persons by denying them (...) access to often contested services such as abortion and contraception. In this paper, we examine the implications of this amendment and situate it in relation to other legislative actions intended to guarantee absolute rights to conscientious objection. In doing so, we argue that the entitlements extended to health care providers by these Bills are overly broad and ignore their potential to allow significant harm to be caused to clients. We then argue that if health care providers should have rights to conscientiously object, then any legislation intended to protect such rights should be limited, specific, and parsimonious. Where it is not, the ideological liberty of HCPs treads dangerously on the physical freedom of their clients. (shrink)

Recent authors hold that the role of historical scholarship within contemporary philosophical practice is to question current assumptions, to expose vestiges or to calibrate intuitions. On these views, historical scholarship is dispensable, since these roles can be achieved by nonhistorical methods. And the value of historical scholarship is contingent, since the need for the role depends on the presence of questionable assumptions, vestiges or comparable intuitions. In this paper I draw an analogy between scientific and philosophical practice, in order to (...) float one role for historical scholarship that is nonreplicable and noncontingent. It has long been acknowledged that cognitive values – features of theories that facilitate understanding, such as ontological parsimony, ideological simplicity, computational ease and fecundity – play a key role within science. The role of some of these values within philosophy also has received attention but left understudied are the values of novelty and conservativeness. These values influence theory choice, the selection of methodology, the setting of research agenda, and the presentation of results; and are best assessed with a historically informed evaluation. This role for historical scholarship is not replicable by nonhistorical methods, and is not contingent on the presence of questionable assumptions, vestiges or comparable intuitions. (shrink)

En metafísica contemporánea, es común trabajar bajo una metodología basada en virtudes teóricas. En caso de disputa, esta metodología nos aconseja elegir la teoría que mejor satisfaga las virtudes teóricas estándar: precisión empírica, fecundidad, poder unificador, consistencia y simplicidad. Sin embargo, no hay consenso sobre cómo deben frasearse tales virtudes, ni sobre cómo ponderarlas. Aquí me concentraré en ofrecer razones a favor de una manera de frasear el principio de parsimonia ideológica, una especie de simplicidad. Defiendo que dicho principio debería (...) decir que, dadas dos teorías T1 y T2, ceteris paribus, si T1 postula menos tipos de expresiones primitvas que T2, entonces es más probable que T1 sea una teoría fiel a que T2 lo sea.

Although the referents of the term social capital merit sustained inquiry, the term impedes understanding because of the historical association of the word capital with economic discourse. As a result of this association, applying the term social capital to civic engagement blurs crucial analytic distinctions. Moreover, there are important ideological consequences to considering things such as bowling leagues to be a form of capital and urging citizens to become social capitalists. The term social capacity, the authors argue, provides the (...) same heuristic benefits as the term social capital without extending illusory promises of theoretical parsimony with the financial/human/social capital trinity.

[Draft of October 2024] David Lewis acclimated us to talk of “nonactual concreta that exist,” regarding talking donkeys and the like. I shall argue that this was not for the best, and try to normalize a way of describing them as “actual concreta that do not exist.” The basis of this is a defense of the Meinongian thesis “there are objects of which it is true that there are no such objects,” re: fictitious and illusory objects. I first formulate the (...) problem of negative existentials in a novel way, and discuss why this new version is more forceful against anti-Meinongians. Additional data is also pressed against anti-Meinongians--e.g., the truth of ‘Pegasus is imaginary’, and a reading of ‘There actually are illusory objects’ where it comes out true. The Meinongian, in contrast, easily and uniformly explains the same data, by allowing the existence Pegasus, pink elephants, and the like. But contra Meinong, these cases suggest that the nonexistent objects are mind-dependent objects, and I clarify and defend this suggestion from several objections. The resulting Meinongianism is thus “conservative” in that it merely acknowledges the sense in which there are mind-dependent objects, imaginary and illusory objects being prime examples. Of special note, the “ideology” is conservative as well in that the typical Meinongian jargon of “nuclear” or “encoded” properties is paraphrased away. New suggestions about the ontology of abstracta, mere possibilia, and impossibilia are sketched in light of this. Comparisons are also made with Crane and McGinn, among others. (shrink)

In the contemporary study of religion there seems to be an exaggeration of the distinction between religion and spirituality, not only to the point of separation, but worse still, in terms of a superiority-inferiority hierarchy that gives rise to a value judgement between spirituality and religion. Could this be a sign of the persisting Western hegemony in the study of religion? This article suggests that the consideration of religion and spirituality as disparate entities may be necessary in some societies but (...) not sufficient for a global perspective. Could there be an integrative model that would lend itself for an inclusive exchange in the study of religion and spirituality? Basing itself particularly within the literature of the psychological study of religion, this essay develops a multidimensional matrix of religion and/or spirituality that attempts to be, at the same time, parsimonious and comprehensive, which includes constructs like ‘religious-spirituality’. Religious-spirituality is suggested to be similar to Allport’s concept of ‘intrinsic religiosity’, having a three dimensional movement marked by an upwardly-directed vertical spirituality, inwardly-directed interior spirituality, and outwardly-directed horizontal spirituality.

In this paper, I motivate the view that quantitative parsimony is a theoretical virtue: that is, we should be concerned not only to minimize the number of kinds of entities postulated by our theories (i. e. maximize qualitative parsimony), but we should also minimize the number of entities postulated which fall under those kinds. In order to motivate this view, I consider two cases from the history of science: the postulation of the neutrino and the proposal of Avogadro's (...) hypothesis. I also consider two issues concerning how a principle of quantitative parsimony should be framed. (shrink)

ABSTRACT Our aim in this article is to offer a new justification for preferring theories that are more quantitatively parsimonious than their rivals. We discuss cases where it seems clear that those involved opted for more quantitatively parsimonious theories. We extend previous work on quantitative parsimony by offering an independent probabilistic justification for preferring the more quantitatively parsimonious theories in particular episodes of theory choice. Our strategy allows us to avoid worries that other considerations, such as pragmatic factors of (...) computational tractability and so on, could be the driving ones in the historical cases under consideration. _1_ Introduction _2_ Three Desiderata _2.1_ Limiting _2.2_ Robustness _2.3_ Breadth _2.3.1_ A limited success for Baker _2.3.2_ Rejecting Baker’s analysis _2.4_ The proposal _3_ Probabilistically Additive Hypotheses and a Bayesian Account: The Limpid Rationale Relativized and Reconsidered _3.1_ Neutrinos and beta decay _3.2_ Avogadro’s hypothesis _3.3_ Postulation of Neptune _4_ Conclusion.

This chapter begins by taking into account alternative views of the ethical subject in Levinas's thought by turning first to its emergence following the coming into being of an autonomous self, depicted principally in the opening sections of Totality and Infinity; and next to its meaning in the context of time and language, as described in his essay “Substitution.” This view is further developed in his major work Otherwise than Being, or Beyond Essence. The chapter then considers the works of (...) Marcel Mauss and Georges Bataille as they bear upon the relation of the individual subject to an economy of the sacred, a self that will be shown to bear striking affinities with the pre-ethical self of Levinas. Finally, it recasts the radical self-giving of Levinas's ethical subject in terms of prodigality and parsimony as they are framed in the conceptual language of classical economics in order to examine some outcomes of unfettered profligacy. The goal is to reconfigure Levinas's ethical subject as one who not only gives but who also stores, not in order to keep but in order to bestow. (shrink)

Ockham’s razor is the idea that simpler hypotheses are to be preferred over more complex ones. In the context of medical diagnosis, this is taken to mean that when a patient has multiple symptoms, a single diagnosis should be sought that accounts for all the clinical features, rather than attributing a different diagnosis to each. This paper examines whether diagnostic parsimony can be justified by reference to probability theory. I argue that while attempts to offer universal justifications of diagnostic (...) parsimony fail, a more constrained use of this diagnostic principle can be supported. (shrink)

Baker argues that quantitative parsimony—the principle that hypotheses requiring fewer entities are to be preferred over their empirically equivalent rivals—is a rational methodological criterion because it maximizes explanatory power. Baker lends plausibility to his account by confronting it with the example of postulating of the neutrino in order to resolve a discrepancy in Beta decay experiments. Baker’s account is initially attractive, but I argue that its details are problematic and that it yields undesirable consequences when applied to the case (...) of astrophysical dark matter. Baker has not succeeded in showing why quantitative parsimony is a theoretical virtue. (shrink)

In his recent book Error Theory: History, Critique, Defence, Jonas Olson attempts to revive the argument from queerness originally made famous by J.L. Mackie. In this paper, we do three things. First, we eliminate four untenable formulations of the argument. Second, we argue that the most plausible formulation is one that depends crucially upon considerations of parsimony. Finally, we evaluate this formulation of the argument. We conclude that it is unproblematic for proponents of moral non-naturalism—the target of the argument (...) from queerness. (shrink)

Some physicalists (Balog 2012, Howell 2013), and most dualists, endorse the acquaintance response to the Knowledge Argument. This is the claim that Mary gains substantial new knowledge, upon leaving the room, because phenomenal knowledge requires direct acquaintance with phenomenal properties. The acquaintance response is an especially promising way to make sense of the Mary case. I argue that it casts doubt on two claims often made on behalf of physicalism, regarding parsimony and mental causation. I show that those who (...) endorse the acquaintance response face special obstacles to invoking parsimony in an argument for physicalism. And I show how acknowledging the phenomenon of acquaintance can ease the dualist’s problems with mental causation, by dispelling three key objections to epiphenomenalism. The most challenging of these objections is that epiphenomenalism blocks an evolutionary explanation of the so-called “hedonic/utility match”. I propose that pleasures and pains, while themselves epiphenomenal, can nonetheless explain positive and negative associations with stimuli, associations that can contribute to fitness. (shrink)

Parsimony is a virtue of empirical theories. Is it also a virtue of philosophical theories? I review four contemporary accounts of the virtue of parsimony in empirical theorizing, and consider how each might apply to two prominent appeals to parsimony in the philosophical literature, those made on behalf of physicalism and on behalf of nominalism. None of the accounts of the virtue of parsimony extends naturally to either of these philosophical cases. This suggests that in typical (...) philosophical contexts, ontological simplicity has no evidential value. (shrink)

Enthymemes are traditionally defined as arguments in which some elements are left unstated. It is an empirical fact that enthymemes are both enormously frequent and appropriately understood in everyday argumentation. Why is it so? We outline an answer that dispenses with the so called "principle of charity", which is the standard notion underlying most works on enthymemes. In contrast, we suggest that a different force drives enthymematic argumentation—namely, parsimony, i.e. the tendency to optimize resource consumption, in light of the (...) agent's goals. On this view, the frequent use of enthymemes does not indicate sub-optimal performance of arguers, requiring appeals to charity for their redemption. On the contrary, it is seen as a highly adaptive argumentation strategy, given the need of everyday reasoners to optimize their cognitive resources. Considerations of parsimony also affect enthymeme reconstruction, i.e. the process by which the interpreter makes sense of the speaker's enthymemes. Far from being driven by any pro-social cooperative instinct, interpretative efforts are aimed at extracting valuable information at reasonable costs from available sources. Thus, there is a tension between parsimony and charity, insofar as the former is a non-social constraint for self-regulation of one's behaviour, whereas the latter implies a pro-social attitude. We will argue that some versions of charity are untenable for enthymeme interpretation, while others are compatible with the view defended here, but still require parsimony to expose the ultimate reasons upon which a presumption of fair treatment in enthymeme reconstruction is founded.

Here, I consider the recent application of phylogenetic methods in historical linguistics. After a preliminary survey of one such method, i.e. cladistic parsimony, I respond to two common criticisms of cultural phylogenies: that cultural artifacts cannot be modeled as tree-like because of borrowing across lineages, and that the mechanism of cultural change differs radically from that of biological evolution. I argue that while perhaps remains true for certain cultural artifacts, the nature of language may be such as to side-step (...) this objection. Moreover, I explore the possibility that cladistic parsimony can be justified even if is true by appealing to the inference pattern known among philosophers as ‘Inference to the Best Explanation’.

Parsimony arguments are advanced in both science and philosophy. How are they related? This question is a test case for Naturalismp, which is the thesis that philosophical theories and scientific theories should be evaluated by the same criteria. In this paper, I describe the justifications that attach to two types of parsimony argument in science. In the first, parsimony is a surrogate for likelihood. In the second, parsimony is relevant to estimating how accurately a model will (...) predict new data when fitted to old. I then consider how these two justifications apply to parsimony arguments in philosophy concerning theism and atheism, the mind/body problem, ethical realism, the question of whether mental properties are causally efficacious, and nominalism versus Platonism about numbers.

The desire to minimize the number of individual new entities postulated is often referred to as quantitative parsimony. Its influence on the default hypotheses formulated by scientists seems undeniable. I argue that there is a wide class of cases for which the preference for quantitatively parsimonious hypotheses is demonstrably rational. The justification, in a nutshell, is that such hypotheses have greater explanatory power than less parsimonious alternatives. My analysis is restricted to a class of cases I shall refer to (...) as additive. Such cases involve the postulation of a collection of qualitatively identical individual objects which collectively explain some particular observed phenomenon. Especially clear examples of this sort occur in particle physics.1Introduction2Particle physics: a case study3Three kinds of simplicity4Explanatory power5Explanation and non‐observation6Parsimony and scientific methodology7Conclusions.

This article presents a novel argument against a common principle of parsimony in philosophy. First, it identifies a widely employed principle of positive ontological parsimony, according to which we should, ceteris paribus, prefer smaller ontologies to larger ontologies. Next, it shows how this principle is used as part of a strategy by which to argue for antirealist positions in many subfields of philosophy: the ockhamistic antirealist strategy. Third, it argues that this principle commits its adherents to an implausible (...) epistemological thesis—the Eroding Ontology Thesis—according to which evidence for the existence of some entity is at least prima facie evidence against the existence of all other entities. Antirealists might decide to adopt a related position, ontological conservatism, according to which we should simply resist changing our ontology, but the article shows that it is independently unjustified. Therefore, it concludes, philosophers have good reason to cease employing one very common antirealist strategy. (shrink)

In this paper I argue that presentism —the view that only present objects exist—can be motivated, at least to some degree, by virtue of the fact that it is more quantitatively parsimonious than rival views.

The chapter discusses the principle of conservatism and traces how the general principle is related to the specific one. This tracing suggests that the principle of conservatism needs to be refined. Connecting the principle in cognitive science to more general questions about scientific inference also allows us to revisit the question of realism versus instrumentalism. The framework deployed in model selection theory is very general; it is not specific to the subject matter of science. The chapter outlines some non-Bayesian ideas (...) that have been developed in model selection theory. The principle of conservatism, like C. Lloyd Morgan's canon, describes a preference concerning kinds of parameters. It says that a model that postulates only lower-level intentionality is preferable to one that postulates higher-level intentionality if both fit the data equally well. The model selection approach to parsimony helps explain why unification is a theoretical virtue. (shrink)

Retributive approaches to the justification of legal punishment are often thought to place exacting and unattractive demands on state officials, requiring them to expend scarce public resources on apprehending and punishing all offenders strictly in accordance with their criminal ill deserts. Against this caricature of the theory, I argue that retributivists can urge parsimony in the use of punishment. After clarifying what parsimony consists in, I show how retributivists can urge reductions in the use of punishment in order (...) to conserve scarce resources for other valuable social purposes, minimize the foreseeable and adverse effects of legal punishment on the innocent, and accommodate the fact that existing societies fail in numerous ways to satisfy the conditions that make retributive punishment fully justified.

This paper offers an account of ideology in terms of social meanings. Such meanings - constituting a cultural technē - are public, conflicting, and fragmented; yet because they guide our practices, they frame our agency and identities. A cultural technē is ideological when it perpetuates unjust subordination; ideology critique offers liberating alternatives.

In the past five years, there have been a series of papers in the journal Evolution debating the relative significance of two theories of evolution, a neo-Fisherian and a neo-Wrightian theory, where the neo-Fisherians make explicit appeal to parsimony. My aim in this paper is to determine how we can make sense of such an appeal. One interpretation of parsimony takes it that a theory that contains fewer entities or processes, (however we demarcate these) is more parsimonious. On (...) the account that I defend here, parsimony is a ‘local’ virtue. Scientists’ appeals to parsimony are not necessarily an appeal to a theory’s simplicity in the sense of it’s positing fewer mechanisms. Rather, parsimony may be proxy for greater probability or likelihood. I argue that the neo-Fisherians appeal is best understood on this interpretation. And indeed, if we interpret parsimony as either prior probability or likelihood, then we can make better sense of Coyne et al. argument that Wright’s three phase process operates relatively infrequently.

Akaike’s framework for thinking about model selection in terms of the goal of predictive accuracy and his criterion for model selection have important philosophical implications. Scientists often test models whose truth values they already know, and they often decline to reject models that they know full well are false. Instrumentalism helps explain this pervasive feature of scientific practice, and Akaike’s framework helps provide instrumentalism with the epistemology it needs. Akaike’s criterion for model selection also throws light on the role of (...) parsimony considerations in hypothesis evaluation. I explain the basic ideas behind Akaike’s framework and criterion; several biological examples, including the use of maximum likelihood methods in phylogenetic inference, are considered. (shrink)

If a parsimony criterion may be used to choose between theories that make different predictions, may the same criterion be used to choose between theories that are predictively equivalent? The work of the statistician H. Akaike (1973) is discussed in connection with this question. The results are applied to two examples in which parsimony has been invoked to choose between philosophical theories-Shoemaker's (1969) discussion of the possibility of time without change and the discussion by Smart (1959) and Brandt (...) and Kim (1967) of mind/body dualism and the identity theory.

The history of ideology and its definition continues to occupy scholars across a range of disciplines. Contrary to the vast volume of earlier work on ideology however, this books provides a challenging new theory of ideology, one that is capable of explaining not only the internal structures of ideologies, but also how ideologies function in society. In formulating theory that is capable of providing the first insights into the internal structures of ideologies while simultaneously explaining how discourse structures may be (...) used in the production and reproduction of ideologies, van Dijk offers a highly important theoretical bridge between the micro and macro structures of society. This book will be essential for all students of discourse studies, communication, social psychology, sociology, and political science. (shrink)

Racism, sexism, and other forms of injustice are more than just bad attitudes; after all, such injustice involves unfair distributions of goods and resources. But attitudes play a role. How central is that role? Tommie Shelby, among others, argues that racism is an ideology and takes a cognitivist approach suggesting that ideologies consist in false beliefs that arise out of and serve pernicious social conditions. In this paper I argue that racism is better understood as a set of practices, attitudes, (...) social meanings, and material conditions, that systematically reinforce one another. Attitudes play a role, but even the cognitive/affective component of ideologies should include culturally shared habits of mind and action. These habits of mind distort, obscure, and occlude important facts about subordinated groups and result in a failure to recognize their interests. How do we disrupt such practices to achieve greater justice? I argue that this is sometimes, but not always, best achieved by argument or challenging false beliefs, so social movements legitimately seek other means. (shrink)

Ockham's razor is popularly phrased as a prohibition against multiplying entities beyond necessity. This prohibition should extend to the receptacle for these entities. To state my thesis more positively and precisely, both qualitative and quantitative parsimony apply to space, time, and possibility. All other things equal, we ought to prefer a hypothesis that postulates less space. Smaller is better. Admittedly, scientists are ambivalent about economizing on the void. They praise simplicity. Yet astronomers have a history of helping themselves to (...) as much empty space as they wish—staggering common sense with the vastness of the universe. This largesse is abetted by an aesthetic bias for sublime hypotheses. Whereas abductions based on beauty converge with parsimony, abductions based on the sublime diverge from parsimony. Awe stifles our inner accountant. Both types of abduction are popular. Both are dubious because we lack independent assurance that the universe is beautiful or sublime. The analogy between space and time supports an extension of parsimony to time. Uniformitarian geologists regarded time as a free resource. However, geologists and cosmologists must justify their postulation of an immense past. Possibility follows suit. Contrary to David Lewis, possible worlds should be minimized. Parsimony about possibilities provides a rationale for parsimony about absences. Absences are possibilities that are not actual. So proliferation of absences entails proliferation of possibilities. We should admit only those absences which do explanatory work. (shrink)
