William Lycan's On Evidence in Philosophy makes noteworthy contributions to many important philosophical topics. The topics discussed here are epistemic justification by explanatory coherence, seeming truths as sources of initial justification, the extent of our philosophical ignorance, the fault in begging the question, the nature of intuitions, and the evidence that intuitions supply. For each topic, an attempt is made to employ work done in the book to advance the philosophical issues.

Most phase III clinical trials today are explanatory. Because explanatory, or efficacy, trials test hypotheses under “ideal” conditions, they are not well suited to providing guidance on decisions made in most clinical care contexts. Pragmatic trials, which test hypotheses under “usual” conditions, are often better suited to this task. Yet, pragmatic, or effectiveness, trials are infrequently carried out. This mismatch between the design of clinical trials and the needs of health care professionals is frustrating for everyone involved, and (...) explains some of the challenges inherent in attempts to enhance knowledge translation and encourage evidence-based practice. The situation is more than simply frustrating, however; it is potentially unethical. Clinical trials must be socially valuable in order to (1) warrant the risks they impose on human research subjects and (2) fairly and efficiently assess new clinical interventions. Most bioethicists would agree that trials that have no social value, for instance, because their results do not have the potential to advance clinical care, should not be performed. What is less widely appreciated is that given limited research resources, trials that are more socially valuable should be preferred to trials that are less socially valuable when all else is equal. With respect to clinical trial design, I argue that while explanatory trials often have some social value, many have less social value than their pragmatic counterparts. On the basis of this general ethical assessment, I provide a preliminary defense of the position that clinical researchers should aim to conduct pragmatic trials, that is, that researchers face a burden of justification related to any idealizing elements added to trial designs.

Foundationalist theories of justification for science were undermined by the theory-ladeness thesis, which has affinities with coherentist epistemologies. A challenge for defenders of coherentist theories of scientific justification is to specify coherence relations relevant to science and to show how these relations make the truth of their bearers likely. Coherence relations include characteristics that pick out better explanations in the implementation of abductive arguments. Empiricist philosophers have attacked abductive reasoning by claiming that explanatory virtues are pragmatic, having (...) no implications regarding truth. However, empiricist's basic beliefs are subject to the same challenges facing abduction, both of which can be met by citing causally coherent etiologies, which are commonplace in biological explanations, and by demonstrating the relevance of causal coherence to truth.

The aim of this paper is to offer an account of epistemic justification suitable for the context of theory pursuit, that is, for the context in which new scientific ideas, possibly incompatible with the already established theories, emerge and are pursued by scientists. We will frame our account paradigmatically on the basis of one of the influential systems of epistemic justification: Laurence Bonjour’s coherence theory of justification. The idea underlying our approach is to develop a set of (...) criteria which indicate that the pursued system is promising of contributing to the epistemic goal of robustness of scientific knowledge and of developing into a candidate for acceptance. In order to realize this we will (a) adjust the scope of Bonjour’s standards—consistency, inferential density, and explanatory power, and (b) complement them by the requirement of a programmatic character. In this way we allow for the evaluation of the “potential coherence” of the given epistemic system. (shrink)

Epistemological Disjunctivism is a view about paradigm cases of perceptual knowledge. Duncan Pritchard claims that it is particularly well suited to accounting for internalist and externalist intuitions. A number of authors have disputed this claim, arguing that there are problems for Pritchard’s way with internalist intuitions. I share the worry. However, I don’t think it has been expressed as effectively as it can be. My aim in this paper is to present a new way of formulating the worry, in terms (...) of an “explanatory challenge”. The explanatory challenge is a simple, yet powerful and illuminating challenge for Epistemological Disjunctivism. It is illuminating in the sense that it shows us why Epistemological Disjunctivism must take on certain internalistically problematic commitments. A secondary aim of this paper is to examine whether the recently much-discussed distinction between justifications and excuses in epistemology can support an adequate response. I will argue that it cannot. (shrink)

This paper aims at elucidating the connection between explanatory considerations and epistemic justification stipulated by explanationism which take epistemic justification to be definable in terms of best explanations. By relying on the notion of truthlikeness, this paper argues that it is rational for a subject to expect the best explanation she has for her evidence to be more truthlike than any of the other potential explanations available to her by virtue of containing a class of propositions that, (...) given her evidence, she is justified in believing. Based on this elucidation of the connection between explanatory considerations and epistemic justification, an explanationist account of the evidential support relation is then offered. (shrink)

I present an explanatory argument for the reasons-first view: It is superior to knowledge-first views in particular in that it can both explain the specific epistemic role of perception and account for the shape and extent of epistemic justification.

This paper defends an account of explanatory reasoning generally, and inference to the best explanation in particular, according to which it first and foremost justifies pursuing hypotheses rather than accepting them as true. This side-steps the problem of why better explanations should be more likely to be true. I argue that this account faces no analogous problems. I propose an account of justification for pursuit and show how this provides a simple and straightforward connection between explanatoriness and (...) class='Hi'>justification for pursuit. (shrink)

Explanation is usually taken to be a relation between certain entities. The aim of this paper is to discuss what entities are suitable as explanatory relata of singular causal explanations, i.e., explanations concerning singular causality relating particular events or other appropriate entities. I outline three different positions. The purely causal approach stipulates that the same entities that are related in the singular causal relation are also linked by the explanatory relation. This position, however, has a problem to distinguish (...) between causation and explanation, two distinct relations allegedly obtaining between the same entities. The linguistic approach states that explanatory relata are linguistic entities of some sort, e.g., statements, propositions, etc. There are various versions of this position. I deal with two of them and try to show that they are unsatisfactory because they transform explanation into some other type of relation. On the first version, explanation is very close to interpretation or clarification of intension and on the second version it seems to be indistinguishable from an evidential relation or justification. I consider these transformations in understanding explanation unnecessary, and consequently reject linguistic views of explanatory relata. The most promising proposal concerning explanatory relata seems to be the mixed view, according to which propositions explain events or other fitting extra-linguistic entities. (shrink)

In this paper, we argue that rather than exclusively focusing on trying to determine if an idealized model fits a particular account of scientific explanation, philosophers of science should also work on directly analyzing various explanatory schemas that reveal the steps and justification involved in scientists’ use of highly idealized models to formulate explanations. We develop our alternative methodology by analyzing historically important cases of idealized statistical modeling that use a three-step explanatory schema involving idealization, mathematical operation, (...) and explanatory interpretation.

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.

A philosophical theory of explanation should provide solutions to a series of problems, both descriptive and normative. The aim of this essay is to establish the claim that this can be best done if one theorizes in terms of explanatory games rather than focusing on the explication of the concept of explanation. The position that is adopted is that of an explanatory pluralism and it is elaborated in terms of the rules that incorporate the normative standards that guide (...) the processes of discovery and justification of explanations as well as the modes of their communication, dissemination, and adoption. They constitute the rules of the explanatory game that the participants are playing. The philosophical project consists in describing and normatively appraising the rules that constitute these games.

This paper considers how explanatory factors can play a role in our ampliative inferential practices. Van Fraassen has argued that there is no possible rational rule that governs ampliative inferences and includes weightings for explanatory beauty. In opposition to van Fraassen, Douven has argued that ampliative inferential rules that include weightings for explanatory factors can be rationally followed. There is, however, a crucial difficulty with Douven's approach: applying the ampliative rule that he suggests leads into irrational belief (...) states. A way to remove the difficulties with Douven's account is suggested. The implications of rationally including explanatory factors in ampliative inferences are then considered.

Proponents of IBE claim that the ability of a hypothesis to explain a range of phenomena in a unifying way contributes to the hypothesis’s credibility in light of these phenomena. I propose a Bayesian justification of this claim that reveals a hitherto unnoticed role for explanatory unification in evaluating the plausibility of a hypothesis: considerations of explanatory unification enter into the determination of a hypothesis’s prior by affecting its ‘explanatory coherence’, that is, the extent to which (...) the hypothesis offers mutually cohesive explanations of various phenomena.

An argument whose conclusion C is essential evidence for one of its premises can provide its target audience with justification for believing C. This is possible because we can enhance our justification for believing a proposition C by integrating it into an explanatory network of beliefs for which C itself provides essential evidence. I argue for this in light of relevant features of doxastic circularity, epistemic circularity, and explanatory inferences. Finally, I confirm my argument with an (...) example and respond to objections. (shrink)

Ausonio Marras has argued that Jaegwon Kim's principle of explanatory exclusion depends on an implausibly strong interpretation of explanatory realism that should be rejected because it leads to an extensional criterion of individuation for explanations. I examine the role explanatory realism plays in Kim's justification for the exclusion principle and explore two ways in which Kim can respond to Marras's criticism. The first involves separating criteria for explanatory truth from questions of explanatory adequacy, while (...) the second appeals to Kim's fine-grained theory of events. I argue that the first response is unconvincing on its own but when coupled with the second might provide a viable way for Kim to avoid Marras's criticism. However, I show that the second strategy is weak from a polemical point of view because Kim's theory of events already assumes what the principle of explanatory exclusion was introduced to establish: the falsity of nonreductive physicalism.

This thesis evaluates several powerful arguments that not only deny that brain states and conscious states are one and the same thing, but also claim that such an identity is unintelligible. I argue that these accounts do not undermine physicalism because they don’t provide any direct or independent justification for their tacit assumptions about a link between modes of presentation and explanation. In my view intelligibility of psychophysical identity should not be based exclusively on the analysis of meaning. The (...) main concern then should be why expect that fully intelligible explanation must be based on the descriptions of the causal roles as modes of presentation. To this effect I propose that we examine "psychological concepts". The psychological concepts are concepts that use descriptions of the functional roles but are about qualities of our experiences. I propose to analyze them in quality space models in order to unveil why phenomenal concepts are expected to refer via descriptions of the causal or functional roles. The quality space should be understood here as a multidimensional space consisting of several axes of relative similarity and differences among the structures of ordering in different modalities of conscious experience. On my proposal it is possible that some axes in the quality space consist of their own quality spaces so we could “zoom in” and “zoom out” into the descriptions of the functional roles and see more clearly what the explanation of certain aspects of consciousness looks like when thought of in terms of psychological concepts.

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.

Classical models of decision making deal fairly well with uncertainty, where settings are well-structured in terms of goals, alternatives, and consequences. Conversely, the typical ill-structured nature of strategy choices remains a challenge for extant models. Such cases can hardly build on the past, and their novelty makes the prediction of consequences a very difficult and poorly robust task. The weakness of the classical expected utility model in representing such problems has not been adequately solved by recent extensions. In this paper (...) we offer an explanatory coherence model for decision making in ill-structured problems. We model alternatives as sets of concurrent causal explanations of reality that act as justifications for action. According to these premises, choice is based on an evaluation of the internal coherence and the consistency of competing explanations of the available evidence. This model is psychologically grounded on causal inference and builds on the connectionist tradition of explanatory coherence. To illustrate the model, we consider the decision of investing in a new technology and we discuss how changes in the structure of alternatives may impact on the solution. We show how the final choice depends on collecting the relevant evidence, making the suitable hypotheses, and drawing the consistent causal explanations linking the two. (shrink)

Earl Conee and Richard Feldman have recently argued that the evidential support relation should be understood in terms of explanatory coherence: roughly, one's evidence supports a proposition if and only if that proposition is part of the best available explanation of the evidence. Their thesis has been criticized through alleged counterexamples, perhaps the most important of which are cases where a subject has a justified belief about the future. Kevin McCain has defended the thesis against Byerly's counterexample. I argue (...) that McCain's defense is inadequate before pointing toward a more promising solution for explanationism. The Byerly–McCain exchange is important because it casts light on the difficult issues of the standards for justification and the nature of epistemic support. Furthermore, McCain's defense of explanationism about epistemic support represents an important recent development of the burgeoning explanationist program in epistemology and philosophy of science.

I present a recent historical case from cosmology—the story of inflationary cosmology—and on its basis argue that solving explanatory problems is a reliable method for making progress in science. In particular, I claim that the success of inflationary theory at solving its predecessor’s explanatory problems justified the theory epistemically, even in advance of the development of novel predictions from the theory and the later confirmation of those predictions.

Although mind-brain identity remains controversial, many other identities of ordinary things with scientific ones are well established. For example, air is a mixture of gases, water is H2O, and fire is rapid oxidation. This paper examines the history of 15 important identifications: air, blood, cloud, earth, electricity, fire, gold, heat, light, lightning, magnetism, salt, star, thunder, and water. This examination yields surprising conclusions about the nature of justification, explanation, and conceptual change.

In this paper, I want to discuss a problem that arises when we try to understand the connections between justification, knowledge, and suspension. The problem arises because some prima facie plausible claims about knowledge and the justification for judging and suspending are difficult to reconcile with the possibility of a kind of knowledge or apt belief that a thinker cannot aptly judge to be within her reach. I shall argue that if we try to accommodate the possibility of (...) this kind of knowledge, we should reject a widely held view about justification. We can correct this mistaken view about the connection between justification and knowledge by connecting justification to a kind of competence, but not the one we might have expected. In the course of this discussion, I shall flag some questions about the explanatory ambitions of the telic virtue-theoretic approach. (shrink)

Recent research in philosophy of science has shown that scientists rely on a plurality of strategies to develop successful explanations of different types of phenomena. In the case of biology, most of these strategies go far beyond the traditional and reductionistic models of scientific explanation that have proven so successful in the fundamental sciences. Concretely, in the last two decades, philosophers of science have discovered the existence of at least two different types of scientific explanation at work in the biological (...) sciences, namely: mechanistic and structural explanations. Despite the growing evidence about the radically different nature of these two types of explanation, no inquiry has been conducted to date to determine the ontological reasons that might underlie these differences, nor the way in which these types of explanations can be systematically related with each other. Here, we aim to cover this gap by connecting this plurality of research strategies with the existence of emergent levels of reality. We argue that the existence of these different—and apparently incompatible—explanatory strategies to account for biological phenomena derives from the existence of “ontological jumps” in nature, which generate different regimes of causation that in turn demand the development of different explanatory frameworks. We identify two of these strategies—mechanistic modelling and network modelling—and connect them to the existence of two ontological regimes of causation. Finally, we relate them with each other in a systematic way. In this vein, our paper provides an ontological justification for the plurality of explanatory strategies that we see in the life sciences. (shrink)

Normative explanations of why things are wrong, good, or unfair are ubiquitous in ordinary practice and normative theory. This paper argues that normative explanation is subject to a justification condition: a correct complete explanation of why a normative fact holds must identify features that would go at least some way towards justifying certain actions or attitudes. I first explain and motivate the condition I propose. I then support it by arguing that it fits well with various theories of normative (...) reasons, makes good sense of certain legitimate moves in ordinary normative explanatory discourse, and helps to make sense of our judgments about explanatory priority in certain cases of normative explanation. This last argument also helps to highlight respects in which normative explanation won’t be worryingly discontinuous with explanations in other domains even though these other explanations aren’t subject to the justification condition. Thus the paper aims not only to do some constructive theorizing about the relatively neglected topic of normative explanation but also to cast light on the broader question of how normative explanation may be similar to and different from explanations in other domains.

Using a religious studies methodology, this paper offers a detailed contextual mapping and a structural configuration of how collective violence is justified in Orthodox Christianity. The research design is explanatory, whereby the functional perspectives of doctrine, ethics and worship are all investigated and probed as phenomena of lived religion and orthopraxy. While predominantly initiatory and pedagogical, the paper also proposes a systematic platform for advanced research on this subject, by flagging contexts, themes and areas of inquiry that a researcher (...) might examine in order to untangle the inner workings of the justification of violence in the mind of the Orthodox. Given the ongoing Russian War on Ukraine, relevant samples are drawn from this case.Contribution: This paper outlines the Orthodox Christian justification of violence from the perspectives of doctrine, ethics and ritual and identifies pivotal areas of ambiguity between orthodoxy and orthopraxy.

Legitimate authorities provide pre‐emptive reasons for action, in that the reasons they provide are not to be added to all other relevant reasons when assessing what to do, but should exclude and replace some of those other reasons. Furthermore, legitimate authorities are dependent in the sense that they ought to issue directives that are based on reasons applying independently to the subjects of the directives. The pre‐emption thesis and the dependence thesis are closely related to the normal justification thesis, (...) which states that the normal justification for authority involves showing that the alleged subject is likely to comply better with reasons applicable to him if he accepts the authoritative directives rather than trying to follow the reasons directly. The chapter ends with a discussion of the nature of the explanatory‐normative reasoning employed in the book. (shrink)

The justification of cognitive claims in theology can be dealt with adequately only if the epistemological issues of metaphorical reference, experiential adequacy, and explanatory progress are seen as crucial problems for the more encompassing problem of rationality in theology.

In this discussion important analogies between the rationality of theological theorizing and (...) the rationality of science are revealed. (shrink)

In this paper I critically discuss and, in the end, reject Morgan’s Canon, a popular principle in comparative psychology. According to this principle we should always prefer explanations of animal behavior in terms of lower psychological processes over explanations in terms of higher psychological processes, when alternative explanations are possible. The validity of the principle depends on two things, a clear understanding of what it means for psychological processes to be higher or lower relative to each other and a (...) class='Hi'>justification of a general preference for explanations that refer to lower psychological abilities. However, I argue that we cannot spell out the idea of a psychological scale in a way that claim is satisfied. I start with the discussion of different interpretations of the notion of a psychological scale. In Sect. 3, I discuss different possible strategies to justify any of those interpretations and argue that all of them fail. Finally, in Sect. 4, I generalize the argument for all possible interpretations of Morgan’s Canon and propose an alternative strategy: We should base our interpretations of animal behavior on more general principles such as evidential support and explanatory power, as followed in other scientific domains.

In this paper, I propose that applying the methods of data science to “the problem of whether mathematical explanations occur within mathematics itself” (Mancosu 2018) might be a fruitful way to shed new light on the problem. By carefully selecting indicator words for explanation and justification, and then systematically searching for these indicators in databases of scholarly works in mathematics, we can get an idea of how mathematicians use these terms in mathematical practice and with what frequency. The results (...) of this empirical study suggest that mathematical explanations do occur in research articles published in mathematics journals, as indicated by the occurrence of explanation indicators. When compared with the use of justification indicators, however, the data suggest that justifications occur much more frequently than explanations in scholarly mathematical practice. The results also suggest that justificatory proofs occur much more frequently than explanatory proofs, thus suggesting that proof may be playing a larger justificatory role than an explanatory role in scholarly mathematical practice.

In Stability and Justification in Hume’s Treatise, Louis Loeb ascribes to Hume a naturalistic account of justified belief, one on which Hume is fundamentally concerned with the question whether stable belief can be achieved. Loeb’s interpretation is systematic, richly explanatory, and powerfully argued. He makes a compelling case that stability plays a central role in Hume’s epistemology. Loeb’s case is so compelling indeed that anyone who wants to defend an alternative interpretation will now have to assimilate or deflect (...) the massive textual evidence in favor of the stability interpretation. I will argue here that, for some passages Loeb cites in favor of the stability interpretation, a veritistic interpretation explains the text at least as well as the stability interpretation does.

I want to examine critically a certain strategy of moral justification which I shall call instrumentalism. By this I mean the view that a moral theory is rationally justified if the actions, life-plan, or set of social arrangements it prescribes can be shown to be the best means to the achievement of an agent's final ends, whatever these may be. Instrumentalism presupposes a commitment to what I shall call the Humean conception of the self. By this I mean a (...) certain way of conceiving the motivational and structural constituents of the self. Briefly, the self on this conception is motivated by its desires for states of affairs that are temporally or spatiotemporally external to the self. And it is structured by the normative requirements of instrumental rationality: The self is conceived as rationally coherent to the extent that theoretical reason calculates and schedules the satisfaction of as many of its desires as possible, with the minimum necessary costs. The motivational and structural elements of the Humean conception of the self combine to form a familiar explanatory model of human agency: We make sense of an agent's behavior by ascribing to her the desire to achieve the ends that she does in fact achieve, and the theoretically rational belief that, given the information and resources available to her, behaving as she did was the most efficient way to do so. I shall want to argue that to the extent that instrumentalism is successful in providing an objective justification of a moral theory - and I shall contend that it cannot be completely successful - it cannot provide a moral justification. But when we attempt to modify it so as to produce a specifically moral justification, we see that either it is impossible to do this, or else the Humean notion of instrumental rationality is doing no justificatory work.

This paper discusses an assumption on which explanationist accounts of the evidential support relation rely with a focus on McCain’s recent account. Explanationist accounts define the relation of evidential support in terms of relations of best explanation that hold between the evidence a subject possesses and the propositions she believes. Such a definition presupposes that the explanatory virtues of what best explains a subject’s body of evidence is indicative of its truth. Yet, recent cases offered in the literature against (...) McCain’s account show that there is no straightforward way of vindicating this assumption. (shrink)

The present PhD thesis is concerned with the question whether good reasoning requires that the subject has some cognitive grip on the relation between premises and conclusion. One consideration in favor of such a requirement goes as follows: In order for my belief-formation to be an instance of reasoning, and not merely a causally related sequence of beliefs, the process must be guided by my endorsement of a rule of reasoning. Therefore I must have justified beliefs about the relation between (...) my premises and my conclusion. -/- The rationality of a belief often depends on whether it is rightly connected to other beliefs, or more generally to other mental states —the states capable of providing a reason to holding the belief in question. For instance, some rational beliefs are connected to other beliefs by being inferred from them. It is often accepted that the connection implies that the subject in some sense ‘takes the mental states in question to be reason-providing’. But views on how exactly this is to be understood differ widely. They range from interpretations according to which ‘taking a mental state to be reason-providing’ imposes a mere causal sustaining relation between belief and reason-providing state to interpretations according to which one ‘takes a mental state to be reason-providing’ only if one believes that the state is reason-providing. The most common worry about the latter view is that it faces a vicious regress. In this thesis a different but in some respects similar interpretation of ‘taking something as reason-providing’ is given. It is argued to consist of a disposition to react in certain ways to information that challenges the reason-providing capacity of the allegedly reason-providing state. For instance, that one has inferred A from B partly consists in being disposed to suspend judgment about A if one obtains a reason to believe that B does not render A probable. The account is defended against regress-objections and the suspicion of explanatory circularity. (shrink)

Apparently, aiming to comply with the norm ‘Believe that P if and only if the proposition that P is true’ can hardly differ from aiming to comply with the norm ‘Believe that P if and only if the proposition that P is epistemically justified’. So one may be tempted to agree with Richard Rorty that the distinction between truth and justification is pragmatically useless because it cannot make any difference ‘when the question is about what I should believe now’. (...) I resist this conclusion by arguing that the distinction between truth and justification is pragmatically useful even if the two properties are indeed normatively coincident. The argument I offer turns on the claim that truth plays an explanatory role that justification is inherently incapable of playing. However, my contention is not just that the distinction between truth and justification is pragmatically useful because truth is a bona fide explanatory notion. It is that the distinction between truth and justification is pragmatically useful because the realization that the former plays an explanatory role that the latter is inherently incapable of playing gives access to reasons which would otherwise escape our attention. If truth is a bona fide explanatory notion, the distinction between truth and justification is pragmatically useful because it is precisely when the question is about what I should believe now that attending to such a distinction will often make a difference – and it will make a difference even if the two properties are in fact normatively coincident.

Recently, many philosophers of religion have sought to defend the rationality of religious belief by shifting the burden of proof onto the critic of religious belief. Some have appealed to extraordinary religious experience in making their case.

This essay examines judicial decision-making from the perspective of Whiteheadian ‘process philosophy’. As such, it seeks to demonstrate how the explanatory categories of process thought can be applied to law and legal reasoning in such a way as to expose the nature of the processes that constitute their development. The essay begins with a description of the judicial task drawn from contemporary theorising about legal argumentation, identified in terms of the separation of contexts of decision-making: discovery and justification. (...) In light of this discussion, the essay then adopts Whiteheadian terminology to provide the basis for an alternative understanding and description of the way that a discrete instance of judicial decision-making develops and is maintained within the decision-making process. In this way, independent of any debate over the separation of contexts, the essay seeks not only to expose and unpack the otherwise hidden micro-processes that contribute to and constitute a legal decision but also, by utilising the same conceptual categories of Whiteheadian process thought, to provide a coherent and consistent account of the macro-processes more commonly observed on the level of law as a social realty. The essay argues that the explanatory power of the categoreal scheme of process thought provides a better tool for understanding these relations on all levels. (shrink)

When does a group justifiedly believe that p? One answer to this question has been developed first by Schmitt and then by Hakli: when the group members jointly accept a reason for the belief. Call this the joint acceptance account of group justification. Their answer has great explanatory power, providing us with a way to account for cases in which the group's justification can diverge from the justification individual members have. Unfortunately, Jennifer Lackey developed a powerful (...) argument against joint acceptance accounts. She argues that these accounts lead to epistemically arbitrary reasons and therefore justification at will. Group justification loses the necessary connection to the world to be truth-conducive. In this paper I develop a new form of a joint acceptance account that can deal with Lackey's examples: the anchored joint acceptance account of group justification. I argue that properly understanding the role of epistemic expectations can help us form the best version of a joint acceptance account. While justification is only generated by joint acceptance of evidence, the evidential expectations towards a group are anchored in the group members. This anchoring guarantees that groups cannot manipulate their ultima facie justification illegitimately. (shrink)

A well-worn French proverb pronounces ‘tout comprendre c’est tout pardonner’ (‘to understand all is to forgive all’). Is forgiveness the inevitable consequence of social scientific understanding of the actions and lives of perpetrators of serious wrongdoing? Do social scientific explanations provide excuses or justifications for the perpetrators of the actions that the explanations purport to explain? In this essay, I seek clarification of these intertwined explanatory and moral questions.

The paper investigates the implications of a nonaprioristic philosophy of science. It starts by developing a scheme of justification which draws its norms from the prevailing paradigm of rationality, which need not be universal or external. If the requirement for normativity is then abandoned we do not end up with a descriptive philosophy of science. The alternative to a prescriptive philosophy of science is a theoretical explanation of scientific decisions and acts. Explanation, rather than mere description, replaces justification; (...) and the paradigm of rationality becomes a scientific paradigm. The implications of these results for the discovery-justification distinction are investigated. An explanatory philosophy of science deals with the generation, as well as with the selection of scientific conjectures: both contexts have an epistemic dimension. * This paper was written under the auspices of the Wolfson Chair Extrordinary of Theoretical Physics, Tel Aviv University.

Direct realism with respect to perceptual experiences has two facets, an epistemological one and a metaphysical one. From the epistemological point of view it involves the claim that perceptual experiences provide immediate justification. From the metaphysical point of view it involves the claim that in perceptual experience we enter into direct contact with items in the external world. In a more radical formulation, often associated with naive realism, the metaphysical conception of direct realism involves the idea that perceptual experiences (...) depend on the items in the external world they are related to. This paper describes a simple account that makes room for immediate justification provided by perceptual experience. The simple account establishes an explanatory relation between the justificatory role of a perceptual experience and the fact that such an experience provides a reason for a belief. The account is evaluated in the light of some objections. Different ways to react to those objections are discussed. It will appear that in order to preserve the explanatory relation established by the simple account, one has to accept naive realism. By breaking the connection between reason and justification, on the other side, one jeopardizes the possibility for perceptual experience to deliver immediate justification. (shrink)

This chapter examines issues surrounding inference to the best explanation, its justification, and its role in different arguments for scientific realism, as well as more general issues concerning explanations’ ontological commitments. Defending the reliability of inference to the best explanation has been a central plank in various realist arguments, and realists have drawn various ontological conclusions from the premise that a given scientific explanation best explains some phenomenon. This chapter stresses the importance of thinking carefully about the nature of (...) explanation in connection with evaluating realists’ appeals to explanatory reasoning and inference to the best explanation.

Modern philosophical literature distinguishes between explanatory reasons and justifying reasons. The former are reasons we appeal to in attempting to explain actions and attitudes. The latter are reasons we appeal to in attempting to justify them.

The idea that truth is the aim of justification is one that is often defended by theorists who uphold different views about the nature of epistemic justification. Despite its prevalence, however, it is not quite clear how one is to cash out the metaphor that justification aims at truth. Some theorists, for example, have objected that the thesis would leave no room for justified false beliefs and unjustified true beliefs. In this paper, I offer an account of (...) what it is for justification to aim at truth using the recently revived idea of difference-making according to which facts often make a difference to other facts. It will be argued that, thus understood, the thesis can illuminate a number of controversial debates in epistemology and that, given its explanatory power, it has a lot to recommend it. (shrink)

Laurence BonJour's (1985) coherence theory of empirical knowledge relies heavily on a traditional foundationalist theory of a priori knowledge. He argues that a foundationalist, rationalist theory of a priori justification is indispensable for a coherence theory. BonJour (1998) continues this theme, arguing that a traditional account of a priori justification is indispensable for the justification of putative a priori truths, the justification of any non-observational belief and the justification of reasoning itself. While BonJour's indispensability arguments (...) have received some critical discussion (Gendler 2001; Harman 2001; Beebe 2008), no one has investigated the indispensability arguments from a coherentist perspective. This perspective offers a fruitful take on BonJour's arguments, because he does not appreciate the depth of the coherentist alternative to the traditional empiricist-rationalist debate. This is surprising on account of BonJour's previous defense of coherentism. Two significant conclusions emerge: first, BonJour's indispensability arguments beg central questions about an explanationist form of coherentism; second, BonJour's original defense of coherentism took on board certain assumptions that inevitably led to the demise of his form of coherentism. The positive conclusion of this article is that explanatory coherentism is more coherent than BonJour's indispensability arguments assume, and more coherent than BonJour's earlier coherentist epistemology.

I discuss a difficulty concerning the justification of the Axiom of Choice in terms of such informal notions such as that of iterative set. A recent attempt to solve the difficulty is by S. Lavine, who claims in his Understanding the Infinite that the axioms of set theory receive intuitive justification from their being self-evidently true in Fin(ZFC), a finite counterpart of set theory. I argue that Lavine's explanatory attempt fails when it comes to AC: in this (...) respect Fin(ZFC) is no better off than the iterative notion. (shrink)

In Cognitive science and philosophy of consciousness, the explanatory gap, following Joseph Levine, refers to the unintelligible link between our conscious mental life and its corresponding objective physical explanation; the gap in our understanding of how consciousness is related to a physical or a physiological substrate :354–361, 1983). David Chalmers holds the explanatory gap as the evidence for a form of metaphysical dualism between consciousness and physical reality. On the other hand, McGinn takes it as an epistemic rather (...) than an ontological gap. Considering the recent advances in neuroscience, however, the reductionist approaches have become replete, which attempt to reduce consciousness and subjectivity to neurobiological accounts. On this view, consciousness mirrors the brain mechanisms, and the self is formulated as an illusory product or construct of neuronal processes. Thomas Fuchs, who is committed to embodied and enactive approaches toward cognition, in Ecology of the Brain, espouses an enactive-ecological perspective concerning the problem of the explanatory gap. He develops an account of human’s life in its dual aspects of the living body and lived body which, on the one hand, defies the ontological dualism and, on the other hand, avoids drifting towards any form of reductionism. Often, the ontologically monistic approaches to the explanatory gap have inclined to a form of reductionism because they conceive consciousness as either identical with its physiological substrate or caused by it, where in both cases, consciousness is claimed to be explainable within the framework of physicalism. Fuchs, however, defends an ontological monism which remains irreconcilable with reductionism. In his account of dual aspects, there is no interaction or impact between the sphere of subjectivity and nature; however, these two aspects imply one another. In this essay, I will develop the philosophical justification of the above reformulation of the mind–body problem and employing the analogy of light will canvass the paradoxical relationship between dual aspects in a phenomenological framework.
