This paper explores the claim that explanation of a group 's behaviour in term of individual mental states is, in principle, superior to explanation of that behaviour in terms of group mental states. We focus on the supposition that individual-level explanation is superior because it is simpler than group -level explanation. In this paper, we consider three different simplicity metrics. We argue that on none of those metrics does individual-level explanation achieve greater simplicity than a group -level alternative. (...) We conclude that an argument against group minds should not lay weight on concerns of explanatory simplicity. (shrink)

Huxley’s Explanatory Gap: There can be no explanation of how states of consciousness arise from interaction among a collection of physical things.

This paper is devoted to Bolzano’s theory of grounding (Abfolge) in his Wissenschaftslehre. Bolzanian grounding is an explanatory consequence relation that is frequently considered an ancestor of the notion of metaphysical grounding. The paper focuses on two principles that concern grounding in the realm of conceptual sciences and relate to traditionally widespread ideas on explanations: the principles, namely, that grounding orders conceptual truths from simple to more complex ones (Simplicity), and that it comes along with a certain theoretical (...) economy among them (Economy). Being spelled out on the basis of Bolzano’s notion of deducibility (Ableitbarkeit), these principles are revealing for the question to what extent grounding can be considered a formal relation.

There are two problems of simplicity. What does it mean to characterize a scientific theory as simple, unified or explanatory in view of the fact that a simple theory can always be made complex (and vice versa) by a change of terminology? How is preference in science for simple theories to be justified? In this paper I put forward a proposal as to how the first problem is to be solved. The more nearly the totality of fundamental physical (...) theory exemplifies the metaphysical thesis that the universe has a unified dynamic structure, so the simpler that totality of theory is. What matters is content, not form. This proposed solution may appear to be circular, but I argue that it is not. Towards the end of the paper I make a few remarks about the second, justificational problem of simplicity. (shrink)

This target article presents a new computational theory of explanatory coherence that applies to the acceptance and rejection of scientific hypotheses as well as to reasoning in everyday life, The theory consists of seven principles that establish relations of local coherence between a hypothesis and other propositions. A hypothesis coheres with propositions that it explains, or that explain it, or that participate with it in explaining other propositions, or that offer analogous explanations. Propositions are incoherent with each other if (...) they are contradictory, Propositions that describe the results of observation have a degree of acceptability on their own. An explanatory hypothesis is acccpted if it coheres better overall than its competitors. The power of the seven principles is shown by their implementation in a connectionist program called ECHO, which treats hypothesis evaluation as a constraint satisfaction problem. Inputs about the explanatory relations are used to create a network of units representing propositions, while coherende and incoherence relations are encoded by excitatory and inbihitory links. ECHO provides an algorithm for smoothly integrating theory evaluation based on considerations of explanatory breadth, simplicity, and analogy. It has been applied to such important scientific cases as Lovoisier's argument for oxygen against the phlogiston theory and Darwin's argument for evolution against creationism, and also to cases of legal reasoning. The theory of explanatory coherence has implications for artificial intelligence, psychology, and philosophy. (shrink)

Paleobiologists often provide simple narratives to explain complex, contingent episodes. These narratives are sometimes ‘one-shot hypotheses’ which are treated as being mutually exclusive with other possible explanations of the target episode, and are thus extended to accommodate as much about the episode as possible. I argue that a provisional preference for such hypotheses provides two kinds of productive scaffolding. First, they generate ‘hypothetical difference-makers’: one-shot hypotheses highlight and isolate empirically tractable dependencies between variables. Second, investigations of hypothetical difference-makers provision (...) class='Hi'>explanatory resources, the ‘raw materials’ for constructing more complex—and likely more adequate—explanations. Provisional preferences for simple, one-shot hypotheses in historical science, then, is defeasibly justified on indirect—strategic—grounds. My argument is made in reference to recent developments regarding the K–Pg extinction. (shrink)

Richard Dawkins has popularized an argument that he thinks sound for showing that there is almost certainly no God. It rests on the assumptions (1) that complex and statistically improbable things are more difficult to explain than those that are not and (2) that an explanatory mechanism must show how this complexity can be built up from simpler means. But what justifies claims about the designer’s own complexity? One comes to a different understanding of order and of simplicity (...) when one considers the psychological counterpart of information. In assessing his treatment of biological organisms as either self-programmed machines or algorithms, I show how self-generated organized complexity does not fit well with our knowledge of abduction and of information theory as applied to genetics. I also review some philosophical proposals for explaining how the complexity of the world could be externally controlled if one wanted to uphold a traditional understanding of divine simplicity. (shrink)

This article generalizes the explanationist account of inference to the best explanation. It draws a clear distinction between IBE and abduction and presents abduction as the first step of IBE. The second step amounts to the evaluation of explanatory power, which consist in the degree of explanatory virtues that a hypothesis exhibits. Moreover, even though coherence is the most often cited explanatory virtue, on pain of circularity, it should not be treated as one of the explanatory (...) virtues. Rather, coherence should be equated with explanatory power and considered to be derivable from the other explanatory virtues: unification, explanatory depth and simplicity. (shrink)

I use Plotinus to present absolute divine simplicity as the consequence of principles about metaphysical and explanatory priority to which most theists are already committed. I employ Phil Corkum’s account of ontological independence as independent status to present a new interpretation of Plotinus on the dependence of everything on the One. On this reading, if something else (whether an internal part or something external) makes you what you are, then you are ontologically dependent on it. I show that (...) this account supports Plotinus’s claim that any entity with parts cannot be fully independent. In particular, I lay out Plotinus’s case for thinking that even a divine self-understanding intellect cannot be fully independent. I then argue that a weaker version of simplicity is not enough for the theist since priority monism meets the conditions of a moderate version of ontological independence just as well as a transcendent but complex ultimate being.

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. 1 Introduction 2 Particle physics: a case study 3 Three kinds of simplicity 4 Explanatory power 5 Explanation and non-observation 6 Parsimony and scientific methodology 7 Conclusions.

I present a novel, collaborative, methodology for linguistics: what I call the ‘explanatory economy’. According to this picture, multiple models/theories are evaluated based on the extent to which they complement one another with respect to data coverage. I show how this model can resolve a long-standing worry about the methodology of generative linguistics: that by creating too much distance between data and theory, the empirical credentials of this research program are tarnished. I provide justifications of such methodologically central distinctions (...) as the competence/performance and core/periphery distinction, and then show how we can understand the push for simplicity in the history of generative grammar in this light. (shrink)

In this note, I discuss the simplicity of rival statistical explanations of a correlation, couched in terms of Reichenbachian Common Cause Systems. Simplicity is analyzed in two components, the so-called intrinsic and contextual simplicity. I show that if one disentangles simplicity from explanatory power then the size of the system provides an adequate for simplicity in both of its dimensions.

It is important to reveal how humans evaluate an explanation of the recent development of explainable artificial intelligence. So, what makes people feel that one explanation is more likely than another? In the present study, we examine how explanatory virtues affect the process of estimating subjective posterior probability. Through systematically manipulating two virtues, Simplicity—the number of causes used to explain effects—and Scope—the number of effects predicted by causes—in three different conditions, we clarified two points in Experiment 1: that (...) Scope's effect is greater than Simplicity's; and that these virtues affect the outcome independently. In Experiment 2, we found that instruction about the explanatory structure increased the impact of both virtues' effects but especially that of Simplicity. These results suggest that Scope predominantly affects the estimation of subjective posterior probability, but that, if perspective on the explanatory structure is provided, Simplicity can also affect probability estimation.

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)

A scientific theory, in order to be accepted as a part of theoretical scientific knowledge, must satisfy both empirical and non-empirical requirements, the latter having to do with simplicity, unity, explanatory character, symmetry, beauty. No satisfactory, generally accepted account of such non-empirical requirements has so far been given. Here, a proposal is put forward which, it is claimed, makes a contribution towards solving the problem. This proposal concerns unity of physical theory. In order to satisfy the non-empirical requirement (...) of unity, a physical theory must be such that the same laws govern all possible phenomena to which the theory applies. Eight increasingly demanding versions of this requirement are distinguished. Some implications for other non-empirical requirements, and for our understanding of science are indicated. (shrink)

One of the most difficult and perplexing tenets of classical theism is the doctrine of divine simplicity. Broadly put, this is generally understood to be the thesis that God is altogether without any proper parts, composition, or metaphysical complexity whatsoever. For a good deal more than a millennium, veritable armies of philosophical theologians – Jewish, Christian and Islamic – proclaimed the truth and importance of divine simplicity. Yet in our own time, the doctrine has enjoyed no such support. (...) Among many otherwise orthodox theists, those who do not just disregard it completely explicitly deny it. However, in a couple of recent articles, William E. Mann has attempted to expound the idea of divine simplicity anew and to defend it against a number of criticisms. He even has gone so far as to hint at reaffirming its importance, suggesting that the doctrine may have a significant amount of explanatory power and other theoretical virtue as part of an overall account of the nature of God, by either entailing or in other ways providing for much else that traditional theists have wanted to say about God. In this paper, I want to take a close look at Mann's formulation of the doctrine and at a general supporting theory he adumbrates in his attempt to render more plausible, or at least more defensible, various of its elements and implications. As Mann has made what is arguably the best attempt to defend the doctrine in recent years, I think that such an examination is important and will repay our efforts. (shrink)

This paper articulates a way to ground a relatively high prior probability for grand explanatory theories apart from an appeal to simplicity. I explore the possibility of enumerating the space of plausible grand theories of the universe by using the explanatory properties of possible views to limit the number of plausible theories. I motivate this alternative grounding by showing that Swinburne’s appeal to simplicity is problematic along several dimensions. I then argue that there are three plausible (...) grand views—theism, atheism, and axiarchism—which satisfy explanatory requirements for plausibility. Other possible views lack the explanatory virtue of these three theories. Consequently, this explanatory grounding provides a way of securing a nontrivial prior probability for theism, atheism, and axiarchism. An important upshot of my approach is that a modest amount of empirical evidence can bear significantly on the posterior probability of grand theories of the universe. (shrink)

Why should anybody care about theoretical simplicity? It is pretty clear that simpler theories don't stand a better chance of being true, just because they are simpler than their competitors. Of course, simpler theories are easier to use in technological applications, and they are more tractable. But that is something engineers should be concerned about. Why should the theoretical scientist be interested in simple theories? ;The principal virtue of simple theories is their facilitation of scientific understanding in virtue of (...) their greater explanatory power. Simple theories are more unified, and they allow important kinds of reasoning about the world. If a theory yields a unified but structure-rich picture of the world, and thereby a high degree of understanding, we can design relevant experiments, form rational expectations, and in general are in a better position to gather relevant data than when we confront the world without any understanding whatsoever. Simple theories are therefore, in virtue of increasing our understanding, epistemically advantageous. That's why the theoretical scientist should be interested in simple theories. ;Of course, since the choice of simple theories does not guarantee getting closer to the truth, the claim that such a choice is epistemically advantageous presupposes that we draw a distinction between the explanatory power of theories and their accuracy. This distinction has not received sufficient attention in the existing literature, and that's why it was so difficult to say exactly what the virtue of simple theories is. Recognizing that explanatory power and accuracy are orthogonal aspects of scientific theories allows us to assign simplicity the role of facilitating understanding and thereby guiding controlled experimentation.

This paper critiques the view that consciousness is likely something extra which accompanies or is produced by neural states, something beyond the functional cognitive processes realized in the brain. Such a view creates the `explanatory gap'between function and nomenology which many suppose cannot be filled by functionalist theories of mind. Given methodological considerations of simplicity, ontological parsimony, and theoretical conservatism, an alternative hypothesis is recommended, that subjective qualitative experience is identical to certain information-bearing, behaviour-controlling functions, not something which (...) emerges from them. This hypothesis explains the isomorphism between the structure of experience and neural organization, while providing a naturalistic account of qualiait's relational properties of informational states, not a sparate ontology of phenomenal essences. On this functionalist view, the hard, empirical problem of consciousness is to discover precisely which neural functions constitute subjective experience. (shrink)

The question of how to frame agential preferences in economics finds one caught between Scylla and Charybdis. If preferences are framed in as minimal and deflationary a manner as revealed preference theory recommends, the theory falls prey to objections about its predictiveness and explanatory power. Alternatively, if too many cognitive and causal intricacies are incorporated into the preference concept, revealed preference models will violate pragmatic norms of model construction, surrendering model simplicity and generality. This paper charts a middle (...) course, arguing that the path to salvation lies through an understanding of revealed preference models as program explanations. (shrink)

This paper suggests a new principle for confirmation theory which is called the principle of explanatory surplus. This principle is shown to be non-Bayesian in character, and to lead to a treatment of simplicity in science. Two cases of the principle of explanatory surplus are considered. The first (number of parameters) is illustrated by curve-fitting examples, while the second (number of theoretical assumptions) is illustrated by the examples of Newton's Laws and Adler's Theory of the Inferiority Complex.

The article considers the opposition of the doctrines of pluralism and monism and their related principles of proliferation and unification in the context of the development of modern cognitive sciences in three important respects for philosophy of science: theoretical, methodological, and explanatory. The article criticizes T. Kuhn’s views of theoretical monism and extends the defense of theoretical pluralism undertaken in author’s previous publications devoted to the conception of theoretical complexes, aimed at the correct description of large groups of theories (...) in the cognitive sciences, such as connectionism, moderate embodied cognition, etc. Pluralism is also defended in methodological dimension. Theoretical pluralism and methodological pluralism are represented as an inevitable consequence of the conception of theoretical complexes and its principle of proliferation calling for the creation/improvement of scientific theories and models which are both compatible and incompatible with respect to a number of basic ontological and methodological assumptions. Theoretical pluralism and methodological pluralism should promote progress with respect to a number of the so-called epistemic qualities, both associated with the approximation of the truth (e.g. predictive success, the ability to give unexpected explanations to known facts, etc.) and not so associated (empirical fit, simplicity according to some interpretations, and the broad scope of the proposed explanations). At the same time the author claims that it is currently not possible to draw a similar conclusion in relation to the explanatory context: if the strategy of explanatory monism or explanatory pluralism will turn out be the preferred strategy for the cognitive sciences should become clear in the course of further research.

A frequent criticism of the neuroscientific approach to consciousness is that its theories describe only 'correlates' or 'analogues' of consciousness, and so fail to address the nature of consciousness itself. Despite its apparent logical simplicity, this criticism in fact relies on some substantive assumptions about the nature and evolution of scientific explanations. In particular, it is usually assumed that, in expressing correlations, neural correlate of consciousness (NCC) theories must fail to capture the causal structure relating brain and mind. Drawing (...) on work in the history and philosophy of science, I argue that this assumption - along with the related claim that even a correct NCC theory would fail to explain consciousness - is grounded in an inadequate conception of the way in which scientific explanations develop. Examination of parallel developments in 20th century biology reveals that, under the right circumstances, seemingly crude correspondences can play an essential role in scientific discovery and can sometimes become central to our everyday understanding of the phenomena in question. A proper understanding of this process clarifies the value of NCC theories and sheds light on the standards by which they should be evaluated. In closing, I describe two specific criteria for evaluating NCC proposals: intertheoretic bridge potential and detailed mapping. (shrink)

Ted Poston's book Reason and Explanation: A Defense of Explanatory Coherentism is a book worthy of careful study. Poston develops and defends an explanationist theory of (epistemic) justification on which justification is a matter of explanatory coherence which in turn is a matter of conservativeness, explanatory power, and simplicity. He argues that his theory is consistent with Bayesianism. He argues, moreover, that his theory is needed as a supplement to Bayesianism. There are seven chapters. I provide (...) a chapter-by-chapter summary along with some substantive concerns. (shrink)

In the current efforts of harmonizing the standards and enforcement of IPRs protection worldwide, this paper explores software piracy trajectories and dynamics in Africa. Using a battery of estimation techniques that ignore as well as integrate short-run disturbances in time-dynamic fashion, we answer the big questions policy makers are most likely to ask before harmonizing IPRs regimes in the battle against software piracy. Three main findings are established. (1) African countries with low software piracy rates are catching-up their counterparts with (...) higher rates; implying despite existing divergent IPRs systems, convergence in piracy rate could be a genuine standard-setting platform. (2) Legal origins do not play a very significant role in the convergence process. (3) A genuine timeframe for standardizing IPRs laws in the fight against piracy is most likely between a horizon of 4–8 years. In other words, full (100 %) convergence within the specified horizon will mean the enforcements of IPRs regimes without distinction of nationality and locality. Policy implications and caveats are discussed. (shrink)

This study examines the efficiency of tools for fighting software piracy in the conditional distributions of software piracy. Our paper examines software piracy in 99 countries over the period 1994–2010, using contemporary and non-contemporary quantile regressions. The intuition for modelling distributions contingent on existing levels of software piracy is that the effectiveness of tools against piracy may consistently decrease or increase simultaneously with the increasing levels of software piracy. Hence, blanket policies against software piracy are unlikely to succeed unless they (...) are contingent on initial levels of software piracy and tailored differently across countries with low, medium and high levels of software piracy. Our findings indicate that GDP per capita, research and development expenditure, main intellectual property laws, multilateral treaties, bilateral treaties, World Intellectual Property Organisation treaties, money supply and respect for the rule of law have negative effects on software piracy. Equitably distributed wealth reduces software piracy, and the tendency not to indulge in software piracy because of equitably distributed wealth increases with the increasing software piracy levels. Hence, the negative degree of responsiveness of software piracy to changes in income levels is an increasing function of software piracy. Moreover, the relationships between policy instruments and software piracy display various patterns: U-shape, Kuznets-shape, S-shape and negative thresholds. A negative threshold represents negative estimates with the increasing negative magnitude throughout the conditional distributions of software piracy. We also discuss the policy implications of our study. (shrink)

Jean Jacques Rousseau (1712-1778) ne cesse de fasciner ses lecteurs, par les controverses internes de ses ecrits. Dans une societe mondialisee, confrontee regulierement aux extremismes religieux qui tentent d'imposer leur vision du monde par la violence, peut-on encore entendre son verdict dans les Lettres ecrites de la Montagne : "La Religion est utile et meme necessaire aux Peuples"? Devant les theories de la laicisation, developpees dans une perspective de secularisation a sens unique, orientees vers l'expulsion de la religion de la (...) sphere publique, la relecture de la pensee politique de Rousseau est indispensable pour elaborer un contrat social acceptable par tous.

En effet, le paradoxe, qui traverse la pensee de Rousseau, trouve son point culminant dans sa controverse avec les encyclopedistes sur le lien entre la politique et la religion. Plus que tout autre philosophe des Lumieres, Jean Jacques Rousseau eclaire la comprehension des defis que posent a notre temps la relation du politique et du religieux. (shrink)

This article integrates previously missing components of government quality into the governance-piracy nexus in exploring governance mechanisms by which global obligations for the treatment of IPRs are effectively transmitted from international to the national level in the battle against piracy. It assesses the best governance tools in the fight against piracy and upholding of intellectual property rights (IPRs). The instrumentality of IPR laws (treaties) in tackling piracy through good governance mechanisms is also examined. Findings demonstrate that: (1) while all governance (...) tools under consideration significantly decrease the incidence of piracy, corruption-control is the most effective weapon; (2) but for voice and accountability, political stability and democracy, IPR laws (treaties) are instrumental in tackling piracy through government quality dynamics of rule of law, regulation quality, government effectiveness, corruption-control, and press freedom. Hence, the need for a policy approach most conducive to expanding development is to implement an integrated system of both IPRs and corollary good governance policies. Moreover, our findings support the relevance of good governance measures in developing countries wishing to complement their emerging IPR regimes. (shrink)

For more than one decade, Andy Clark has defended the now-famous extended mind thesis, the idea that cognitive processes leak into the world. In this paper I analyse Clark’s theoretical justification for the thesis: explanatory simplicity. I argue that his way of justifying the thesis leads into contradiction, either at the level of propositional attitude ascriptions or at the theoretical level. I evaluate three possible strategies of dealing with this issue, concluding that they are all likely to fail (...) and that therefore, as regards explanatory simplicity, the burden of proof is on Clark’s side. The paper divides into two main sections: in “Simplicity and Coherence”, I define the two concepts that are important in this context (simplicity and explanatory coherence). In “How to Cope with Coherence”, these two concepts are applied to the central thought experiment, the Inga/Otto case. It will be shown that justifying the extended mind thesis by reference to simplicity may cause trouble, because ‘extended’ behavioural descriptions are likely to yield rather complicated explanations.

In a comparison of the principles of special relativity and of quantum mechanics, the former theory is marked by its relative economy and apparent explanatory simplicity. A number of theorists have thus been led to search for a small number of postulates - essentially information theoretic in nature - that would play the role in quantum mechanics that the relativity principle and the light postulate jointly play in Einstein's 1905 special relativity theory. The purpose of the present paper (...) is to resist this idea, at least in so far as it is supposed to reveal the fundamental form of the theory. It is argued that the methodology of Einstein's 1905 theory represents a victory of pragmatism over explanatory depth; and that its adoption only made sense in the context of the chaotic state state of physics at the start of the 20th century - as Einstein well knew.

In an earlier discussion, I argued that Kant's moral theory satisfies some of the basic criteria for being a genuine theory: it includes testable hypotheses, nomological higher-and lower-level laws, theoretical constructs, internal principles, and bridge principles. I tried to show that Kant's moral theory is an ideal, descriptive deductive-nomological theory that explains the behavior of a fully rational being and generates testable hypotheses about the moral behavior of actual agents whom we initially assume to conform to its theoretical constructs. I (...) argued that the moral "ought" is best understood as the "ought" of tentative prediction expressed in the range of uses of the German sollen; and that the degree to which such a theory is well-confirmed is a function of the degree to which we actually judge individual human agents, on a case-by-case basis, to be motivated by rationality, stupidity, or moral corruption in their actions. I assume that a similar case could be made for other major contenders, such as Utilitarianism or Aristotelianism. But there still remains unanswered the question of which of these theories is the best among the available alternatives. To answer this question, further criteria of selection must be invoked. Among these are structural elegance and explanatory simplicity, but even these do not exhaust the desiderata for an adequate moral theory. More pressing in the case of moral theory is the requirement that the theory enable us to understand all the available data of moral experience; that the theory be sufficiently inclusive that in the formulation of its descriptive laws and practical principles, it be capable of identifying as morally significant all the behavior to which moral praise, condemnation, or acquittal is a relevant and appropriate response.

The aim of this paper is to defend the ontological Principle of Sufficient Reason (PSR-O). I analyse various versions of this principle and various ways of justifying it. Then I attempt to challenge some counterexamples allegedly refuting a universal application of the PSR-O. There are standard and non-standard versions of the PSR-O. The PSR-Ostand can only be valid if there are no chains of contingent reasons and outcomes with first modules, i.e. all chains are actually infinite. However, there are serious (...) arguments against this possibility. The necessary condition of the PSR-Onon-stand is the existence of a necessary substance: that substance would be a direct reason of certain contingent states of affairs obtaining in its domain, and those states of affairs would then be indirect reasons for all other contingent states of affairs and things. There are two advantages of the PSR-Onon-stand: a nomological unity of the world and explanatory simplicity. (shrink)

On one classical conception of God, God has no parts, not even metaphysical parts. God is not composed of form and matter, act and potency, and he is not composed of existence and essence. God is absolutely simple. This is the doctrine of Absolute Divine Simplicity. It is claimed that ADS implies a modal collapse, i.e. that God’s creation is absolutely necessary. I argue that a proper way of understanding the modal collapse argument naturally leads the proponent of ADS (...) to reject a particular premise of the argument: namely, “the same identical cause brings about the same effect.” However, I argue that the rejection of that premise leads to a deeper problem for ADS. It leads to an explanatory gap: how can we explain the relevant type of indeterminism in an absolutely simple God? (shrink)

There has in recent years been a significant surge of interest in non-materialist accounts of the mind. Property dualists hold that all substances (concrete particulars that persist over time) are material, but mental properties are distinct from physical properties. Substance dualists maintain that the mind or person is a non-material substance. This article considers the prospects for substance dualism given the current state of the debate. The best known type of substance dualism, Cartesian dualism, has traditionally faced a number of (...) objections, but many contemporary philosophers have sought to avoid these by formulating novel versions of the view. I identify three central claims held in common by all forms of substance dualism, consider recent arguments for these claims, and assess how successfully different types of substance dualism respond to the traditional objections. I argue that most contemporary forms of the view still face one or more of three major challenges, from bundle theories of the self, from the recently developed “phenomenal concepts strategy”, and from worries about explanatory simplicity.

The aim of this paper is to defend the Principle of Sufficient Reason (PSR). I analyse various versions of this principle (and their structure) and various ways of justifying it. Then I present and attempt to challenge some counterexamples allegedly refuting a universal application of the PSR. One can distinguish three versions of the PSR: for each state of affairs there is a sufficient reason for its obtaining (PSR-O); for each true proposition there is a direct or indirect justification (PSR-E); (...) for each state of affairs there exists an intellectual duty to search for a sufficient reason for obtaining of that state of affairs, and for each known true proposition - to search for its justification (PSR-M). There are standard and non-standard versions of the PSR-O. The PSR-O stand can be only valid if there are no chains of contingent reasons and outcomes with first modules, i.e. all chains are actually infinite. However, there are serious (yet debatable) arguments against the possibility of such infinity. The necessary condition of the PSR-O non-stand universal working is the existence of a necessary substance (thing): that substance would be a (free) reason of certain contingent states of affairs obtaining in its domain, and those states of affairs would then be reasons for all other contingent state of affairs and things. (The principle does not require a necessary substance to have its own reason). Limiting the chain of reasons to contingent states of affairs ended with a necessary state (if this state is a reason by necessity) would lead to the paradox of universal necessarism. An ontological \"cost\" of holding the PSR-O non-stand is a postulate of the existence of the necessary, supra-natural substance, i.e. God. However, there are serious advantages of the view which accepts that the PSR-O non-stand is generally valid: a nomological unity of the world and explanatory simplicity. (shrink)

I review and challenge the views on simplicity and its role in linguistics put forward by Ludlow. In particular, I criticize the claim that simplicity—in the sense pertinent to science—is nothing more than ease of use or “user-friendliness”, motivated by economy of labor. I argue that Ludlow’s discussion fails to do justice to the diversity of factors that are relevant to simplicity considerations. This, in turn, leads to the neglect of crucial cases in which the rationale for (...) simplification is unmistakably epistemic, as well as instances where simplicity is part of the content of substantive, empirical hypotheses. I illustrate these points with examples from the history of generative linguistics, such as: the shaping influence exerted by simplicity, via its involvement in the notion of “linguistically significant generalization”, its methodological and substantive contribution to the goal of explanatory adequacy, and its central role in the Minimalist Program’s search “beyond explanatory adequacy”.

The epistemological chasm between how we (implicitly and subjectively) perceive or imagine the actual world and how we (explicitly and “objectively”) think of its underlying entities has motivated perhaps the most disconcerting impasse in human thought: the explanatory gap between the phenomenal and physical properties of the world. Here, I advocate a combination of philosophical skepticism and simplicity as an informed approach to arbitrate among theories of consciousness. I argue that the explanatory gap is rightly a gap (...) in our understanding, but one that is not surprising; and we being observers biased by our first-person perspective and our existence may both hinder and (the realization we have them) assist our reasoning. Further, I unfold the concept of observer into two distinct notions based on its functional and phenomenal aspects, and exploit this device to elucidate the subject-observer relationship. Then, I proceed to analyze the philosophical zombie dilemma. Lastly, I contend that from a skeptical viewpoint, panpsychism (or neutral monism) is the most parsimonious doctrine accounting for the explanatory gap, and suggest that it would be possible to make headway in the hard problem of consciousness by uncovering non-trivial causal relationships between qualia states and functional states, if routine and controlled manipulation of neural circuits were easily available.

There is a need to bring about a revolution in the philosophy of science, interpreted to be both the academic discipline, and the official view of the aims and methods of science upheld by the scientific community. At present both are dominated by the view that in science theories are chosen on the basis of empirical considerations alone, nothing being permanently accepted as a part of scientific knowledge independently of evidence. Biasing choice of theory in the direction of simplicity, (...) unity or explanatory power does not permanently commit science to the thesis that nature is simple or unified. This current ‘paradigm’ is, I argue, untenable. We need a new paradigm, which acknowledges that science makes a hierarchy of metaphysical assumptions concerning the comprehensibility and knowability of the universe, theories being chosen partly on the basis of compatibility with these assumptions. Eleven arguments are given for favouring this new ‘paradigm’ over the current one. (shrink)

In this article, I will provide a critical overview of the form of non-deductive reasoning commonly known as “Inference to the Best Explanation” (IBE). Roughly speaking, according to IBE, we ought to infer the hypothesis that provides the best explanation of our evidence. In section 2, I survey some contemporary formulations of IBE and highlight some of its putative applications. In section 3, I distinguish IBE from C.S. Peirce’s notion of abduction. After underlining some of the essential elements of IBE, (...) the rest of the entry is organized around an examination of various problems that IBE confronts, along with some extant attempts to address these problems. In section 4, I consider the question of when a fact requires an explanation, since presumably IBE applies only in cases where some explanation is called for. In section 5, I consider the difficult question of how we ought to understand IBE in light of the fact that among philosophers, there is significant disagreement about what constitutes an explanation. In section 6, I consider different strategies for justifying the truth-conduciveness of the explanatory virtues, e.g., simplicity, unification, scope, etc., criteria which play an indispensable role in any given application of IBE. In section 7, I survey some of the most recent literature on IBE, much of which consists of investigations of the status of IBE from the standpoint of the Bayesian philosophy of science. (shrink)

We propose a formal framework for interpretable machine learning. Combining elements from statistical learning, causal interventionism, and decision theory, we design an idealised explanation game in which players collaborate to find the best explanation for a given algorithmic prediction. Through an iterative procedure of questions and answers, the players establish a three-dimensional Pareto frontier that describes the optimal trade-offs between explanatory accuracy, simplicity, and relevance. Multiple rounds are played at different levels of abstraction, allowing the players to explore (...) overlapping causal patterns of variable granularity and scope. We characterise the conditions under which such a game is almost surely guaranteed to converge on a optimal explanation surface in polynomial time, and highlight obstacles that will tend to prevent the players from advancing beyond certain explanatory thresholds. The game serves a descriptive and a normative function, establishing a conceptual space in which to analyse and compare existing proposals, as well as design new and improved solutions. (shrink)
