Brain images are used both as scientific evidence and to illustrate the results of neuroimaging experiments. These images are apt to be viewed as photographs of brain activity, and in so viewing them people are prone to assume that they share the evidential characteristics of photographs. Photographs are epistemically compelling, and have a number of characteristics that underlie what I call their inferential proximity. Here I explore the aptness of the photography analogy, and argue that although neuroimaging does bear (...) important similarities to photography, the details of the generation and analysis of neuroimages significantly complicate the relation of the image to the data. Neuroimages are not inferentially proximate, but their seeming so increases the potential for misinterpretation. This suggests caution in appealing to such images in the public domain. (shrink)

The vagaries of evidential reasoning in archaeology are notorious: the material traces that comprise the archaeological record are fragmentary and profoundly enigmatic, and the inferential gap that archaeologists must cross to constitute them as evidence of the cultural past is a peren­nial source of epistemic anxiety. And yet we know a great deal about the cultural past, including vast reaches of the past for which this material record is our only source of evidence. The contents of this record stand (...) as evidence only under interpretation, but however much a construct it is, archaeological evidence has a striking capacity to disrupt settled assump­tions, redirecting inquiry and expanding interpretive horizons in direc­tions no one could have anticipated. It is this capacity for constraining inference and interpretation that I am concerned to understand. I outline a model of evidential reasoning based on archaeological practice that integrates insights drawn from philosophical theories of confirmation, model building and hypothesis testing. Given growing interest in the uses of material evidence in fields that had been resolutely text-based, the archaeological principles of evidential reasoning may have much wider reach than this particular social/historical discipline.

This study investigated whether some Japanese intransitive verbs, called agent-implying intransitive verbs, are processed differently from other ordinary intransitive verbs. These verbs are special in that they denote agentive events, but they are intransitive verbs, which only allow the patient/theme to be the only nominatively marked argument. The priming experiment was designed based on the situation model theory, assuming that verbs with an agentive semantic structure (e.g., ordinary transitive verbs) has a shorter causal inferential distance than those with (...) a non-agentive semantic structure (e.g., ordinary intransitive verb). In the experiment, participants were instructed to read two sentences that formed a story, of which the second sentence was either a transitive or intransitive sentence. The participants then answered a related question about general knowledge, and their response times were measured. The results show that, whereas the mean response time in the ordinary intransitive condition was significantly longer than that in the ordinary transitive condition, the mean response time in the agent-implying intransitive condition was not significantly different from that of the corresponding transitive condition, suggesting that agent-implying intransitive verbs are interpreted as agentive. The findings suggest that agent-implying intransitive verbs instantly evoke agentivity, whereas ordinary intransitive verbs do not. The theoretical implications of the findings are discussed.

‘Visualisations play an important role in science’, this seems to be an uncontroversial statement today. Scientists not only use visual representations as means to communicate their research results in publications or talks, but also often as surrogates for their objects of interest during the process of research. Thus, we can make a distinction between two contexts of usage here, namely the explanatory and the exploratory context. The focus of this paper is on the latter one. Obviously, using visualisations as surrogates (...) for their objects of depiction presupposes the assumption that the former can tell us something relevant about the latter. Thus, a particular referential relation between object and image has to be assumed that can transfer the relevant information. Furthermore, as science is a collaborative enterprise – a social activity – this information has to be intersubjectively accessible and stable. Nonetheless, philosophers of science still quarrel about the epistemic and ontological status of such visualisations. After all, they are means to visualise theoretical entities, such as the Higgs Boson, i.e. entities that are principally not observable with the unaided eye. Especially the significant reliance on information technology devices to access this world of the unobservable provokes a lot of suspicion with regard to the referential status of such visualisations. In this sense, quite a few philosophers adopt social constructivism as an explanatory hypothesis. A particular image is constructed with the aid of instruments and theoretical assumptions; hence it does not refer to an entity outside this system. In this paper, I will critically analyse this assumption and try to argue for an alternative point of view. (shrink)

Category-based induction is an inferential mechanism that uses knowledge of conceptual relations in order to estimate how likely is for a property to be projected from one category to another. During the last decades, psychologists have identified several features of this mechanism, and they have proposed different formal models of it. In this article; we propose a new mathematical model for category-based induction based on distances on conceptual spaces. We show how this model can predict most of the properties (...) of this kind of reasoning while providing a solid theoretical foundation for it. We also show that it subsumes some of the previous models proposed in the literature and that it generates new predictions. (shrink)

The recent wave of data on exoplanets lends support to METI ventures (Messaging to Extra-Terrestrial Intelligence), insofar as the more exoplanets we find, the more likely it is that “exominds” await our messages. Yet, despite these astronomical advances, there are presently no well-confirmed tests against which to check the design of interstellar messages. In the meantime, the best we can do is distance ourselves from terracentric assumptions. There is no reason, for example, to assume that all inferential abilities (...) are language-like. With that in mind, I argue that logical reasoning does not have to be couched in symbolic notation. In diagrammatic reasoning, inferences are underwritten, not by rules, but by transformations of self-same qualitative signs. I use the Existential Graphs of C. S. Peirce to show this. Since diagrams are less dependent on convention and might even be generalized to cover non-visual senses, I argue that METI researchers should add some form of diagrammatic representations to their repertoire. Doing so can shed light, not just on alien minds, but on the deepest structures of reasoning itself. (shrink)

DOI: 10.1080/00031305.2018.1564697 When the editors of Basic and Applied Social Psychology effectively banned the use of null hypothesis significance testing (NHST) from articles published in their journal, it set off a fire-storm of discussions both supporting the decision and defending the utility of NHST in scientific research. At the heart of NHST is the p-value which is the probability of obtaining an effect equal to or more extreme than the one observed in the sample data, given the null hypothesis and (...) other model assumptions. Although this is conceptually different from the probability of the null hypothesis being true, given the sample, p-values nonetheless can provide evidential information, toward making an inference about a parameter. Applying a 10,000-case simulation described in this article, the authors found that p-values’ inferential signals to either reject or not reject a null hypothesis about the mean (α = 0.05) were consistent for almost 70% of the cases with the parameter’s true location for the sampled-from population. Success increases if a hybrid decision criterion, minimum effect size plus p-value (MESP), is used. Here, rejecting the null also requires the difference of the observed statistic from the exact null to be meaningfully large or practically significant, in the researcher’s judgment and experience. The simulation compares performances of several methods: from p-value and/or effect size-based, to confidence-interval based, under various conditions of true location of the mean, test power, and comparative sizes of the meaningful distance and population variability. For any inference procedure that outputs a binary indicator, like flagging whether a p-value is significant, the output of one single experiment is not sufficient evidence for a definitive conclusion. Yet, if a tool like MESP generates a relatively reliable signal and is used knowledgeably as part of a research process, it can provide useful information. (shrink)

Christopher Norris DERRIDA AT YALE: THE "DECONSTRUCTIVE MOMENT" IN MODERNIST POETICS IN seven types of ambiguity, William Empson breezily remarked of his critical method that it was "either all nonsense or all very startling and new." The reactions went very much as Empson predicted, with a whole new school of criticism eagerly latching on to the idea of multiple meanings in poetry, while the sober-sided scholars indignantly attacked his wayward "misreadings" and flagrant anachronisms. At present, there is a similar controversy (...) raging around the figure of Jacques Derrida, whose influence on literary critics—mainly the Yale school of Geoffrey Hartman, Harold Bloom and J. Hillis Miller— occupies the forefront of debate in current theoretical exchange. Apart from all the sideshow of polemics, this parallel with Empson is a useful jumping-off point for an approach to Derrida and the implications of his writing. Empson opened up the literary text to a practice of reading which released as many ambiguities, overtones, and hints of recondite meaning as the analyst could reasonably claim to find in it. Reason, or commonsense judgment, still played an arbitrating role, since Empson wanted his readings at least to match something in the credible intention—at whatever "unconscious" level—of the author concerned. Subsequently, Empson has taken issue with the American New Critics on precisely this ground of authorial intention. Where they have dismissed all such considerations as outside the critic's proper interest or competence—treating the text as a "verbal icon," detached from any speculative background of motive or intent—Empson has come out in sturdy defense of "intentionalist" readings, based on available evidence of what the poet was trying to express. In other words, Empson, for all his dazzling inventiveness, held to a notion of the author as (implicitly) a self-possessed creator of meanings, one whose intentions demand critical respect, however broadly that requirement is to be interpreted in practice. Anglo-American criticism 242 Christopher Norris243 has lately been much preoccupied with the question of whether—or exactly how far—an author's original "meaning" can be recovered by close attention to his text. E. D. Hirsch's Validity in Interpretation is a classic if long-winded statement of the conservative view: that the critic's obligation is to come as close as possible to establishing what an author most probably meant in using language as. he did.3 The discipline involved is partly a matter of historical semantics (drawing a limit or "horizon" of possible meanings in context), and partly a matter of interpretative tact and sympathy. Hirsch grounds his argument on the Kantian premise that a text is in some sense the surrogate voice of its author, and that texts must therefore be treated, like people, as ends in themselves, and not means toward the critic's display of self-advertising brilliance. All the same, Hirsch has to acknowledge that authorial intention, as such, is beyond the grasp of this reconstructive program, which offers at best a kind of inferential yardstick for narrowing down the range of semantic potential. The problem which Hirsch never quite gets to grips with, despite his elaborate argumentation, is the fact that texts come across to us always from a distance of time, of experience or culture, which makes their meaning more or less opaque and problematic. The author is not simply there in the text, a self-authenticating "voice" of intent, as Hirsch (in his more sanguine moments) would have us believe. One might expect some such assurance from the homely narrative address of a novelist like Fielding, or the intimate soul-baring style of Wordsworth's poetry. Yet Fielding is as cunning a narrative tactician as any, his "voice" a shifting multitude of ironies and ploys; while Wordsworth manages a complex and selective rhetoric of memory which (as recent critics have shown) by no means communicates the "unmediated vision" of purely personal address. Hirsch yields a hostage to the relativist case by proposing a distinction between "meaning" (that which inheres in the text, and which the critic is duty-bound to preserve), and "significance" (the purely associative values which change with the passage of time and make room for rival or updated interpretations...

Attempts within sociolinguistics to model the African American speech community require a sound account of what a competent participant knows when they give correct interpretations of utterances made within such a community, a phenomenon any larger theory of language use ought to address. To provide this account, I reconstruct a line of argument from the philosophical history of discussions on African American speech communities. I give this history in terms of pragmatic arguments, that is, in terms of the ability of (...) vernacular speakers to manage the "slip" between speaker meaning and conventional meaning so as to effectively communicate, and thus be interpretable to competent auditors. ;In the writings of African American philosophers Alexander Crummell and Alain Locke especially, the general pragmatic strategy is to take the regulative background of speech acts to play a central role in vernacular interpretation, particularly as it relates language use to patterns of interpretation available to a speech community and to communicative aspects of the socialization of members of that community . In terms of meaning, interpretation is seen by Crummell as a function of publicly accessible meaning; he endorses the claim that the content which a word expresses is an idea in the mind of a speaker--what I call the Semantic Identity Thesis. Locke's insight, however, that cognitive meaning and content-bearing linguistic vehicles can be assessed independently provides him with the leverage to treat speaker meaning and symbol meaning as distinct components of a speaker's competence to successfully interpret utterances--what I call the Semantic Distance Thesis. ;Using these accounts to model inferences in communication, I argue that a complete account of interpretation will show how a speaker accesses inferential, conventional and social knowledge. These sorts of knowledge are tied to the prevailing norms emerging from a regulative background for communication within the language use of a speech community. In this way, the slip between conventional meaning and speaker meaning can be understood as structuring the communicative context of vernacular speech, in that social knowledge plays a central role in effective interpretive inference.

Jean Mandler proposes an original and richly detailed theory of how concepts relate to sensory and motor capacities. I focus on her claims about conceptual representations and the processes that produce them. On her view, concepts are declarative representations of object kind information. First, I argue that since sensorimotor representations may be declarative, there is no bar to percepts being constituents of concepts. Second, I suggest that concepts track kinds and other categories not by representing kind information per se, but (...) rather by being subject to the appropriate sort of inferential dispositions. These dispositions themselves may apply equally to perceptual and non-perceptual representations. Third, I argue that Mandler's proposed redescriptive mechanism for producing conceptual primitives can be viewed as a kind of Fodorian triggering device. Hence there may be less distance between her view and Fodor's than either one has supposed. I suggest that redescription needs to be supplemented with several other kinds of more flexible and open-ended concept learning mechanisms. Finally, I briefly sketch the view of conceptual development that results from adopting these proposals and contrast it with Mandler's. (shrink)

Transitive inference (TI) plays a part in many aspects of reasoning, and is usually assessed using variants on a particular task dubbed the “IP-paradigm”. Advocates of this paradigm assume it ensures that subjects must use deduction to solve the inferential questions. The present task with 63 adults strengthened this claim by removing all possible perceptual cues and limiting as far as possible all cues from the training procedure itself. Response speed and accuracy were measured as premises were learned. Findings (...) show that when over-training and non-logical cues are avoided, adults nevertheless reach high levels of overall performance. However, key indexes of Lexical Marking, Relative-End-Anchoring, and Symbolic Distance are largely absent or in the opposite direction to the generally accepted view at the start of training, and are present only for response time (RT) at the end of training. The widely accepted strategy of retrieval from an integrated mental representation does emerge; but only after an initial associative process and a deductive process. Regarding three comparisons critical for demonstrating deductive TI, the inference was more demanding than its antecedents both in terms of accuracy and RT, and both after initial and final training. Existing theories of TI account for some of these findings, but what is required is a theory accommodating them all. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reply to Vaidya, Guhe, and Williams on the Bloomsbury Translation of the Tattva-cintā-maṇi of GaṅgeśaStephen Phillips (bio)More or less happy with the reviews, I would like mainly, in response, to identify advances made in the study of Gaṅgeśa. Anand Vaidya articulates a clearer overview of Gaṅgeśa's theory of knowledge; Eberhard Guhe shows a better way to render the notion of vyāpti, "pervasion," which is central in the theory of (...) inference as a knowledge source; and Michael Williams, too, shows need for improvement on that score as well as for elaboration of matters taken up by classical commentators that are given short shrift in my running comments. For example, whereas long discussions are provoked by Gaṅgeśa's definition of "knowledge," pramā, major points in the purvapakṣa in the section on proving the existence of an īśvara, a "Lord," seem, as Williams says, "threadbare."Vaidya, following Burge (2003), introduces a distinction between entitlement and justification: entitlement is the kind of unreflective epistemic warrant delivered by Gaṅgeśa's pramāṇa, "knowledge sources," working automatically in our everyday lives, whereas justification requires self-conscious certification, prāmāṇya-jñapti. Thereby splitting the horns of a dilemma posed by internalist accounts of knowledge in opposition to externalist ones, Burge and Vaidya are able to incorporate the most [End Page 519] attractive features of each approach. The entitlement/justification distinction cashes out, I may add, to Vaidya's elucidation, Nyāya's deeply held doctrine of parataḥ-prāmāṇya, "certification by another," against the view of "intrinsic certification," svataḥ-prāmāṇya, of Prabhākara and others. As Williams notes, Prābhākara positions, for which Gaṅgeśa sometimes shows sympathy, may have led him to presume that an anubhava—"awareness" or "presentational experience" in my translation, "fresh news" in Matilal's snappy rendering—is an episode of knowledge, pramā, "unless one knows otherwise," bādhakam vinā.On reflection, one sees that such a presentation (it could be perceptual, inferential, analogical, or testimonial) has been produced by a pramāṇa, or, in abnormal cases, not, and so by a "pramāṇa-pretender," a pramāṇaābhāsa, as in seeing a mirage. Again, an anubhava is not just any old cognition or "thought" (pace Das 2021, p. 162); it is defined as nonrecollective. Unlike a deliverance of a genuine pramāṇa, some instances may, on examination, prove to be a-pramā, "non-knowledge," but are, nevertheless, at the animal level, sufficient to provoke and guide action that would not be unhesitating were there doubt in any way. A thirsty Maya, in Vaidya's example, would naturally move in the direction of the water she "sees." But she would hesitate were she to learn from her friend about the unreliability of water-perception in the current circumstances. At the reflective level, where she is unsure whether the anubhava she apperceives is pramā or apramā, her action, including speech (implying assertability), is altered.So far so good in Vaidya's reconstruction. But Gaṅgeśa does not himself pronounce on the question of whether, after learning about the defeater, Maya would still be entitled to her perceptual belief that there is water in the distance. In the volumes under review, I assumed that she would not be "justified" and indeed that she would no longer have the belief (if we may speak about "beliefs"). The defeater grasped at the reflective level would mean not only that she could not certify the perceptual deliverance but also that there would be no knowledge. Clearly, she can't certify it, and thus, as Vaidya reasons, loses the right to assert. But maybe he's correct that, according to Gaṅgeśa's sensibilities, she does not lose the perceptual knowledge. She would remain entitled to her belief.Personally, I think this is wrong, but Vaidya's understanding does have the merit of explaining why some later Naiyāyikas apparently took absurd positions on epistemic luck (Bhattacharya 1996, p. ix). I think that Maya would lose her entitlement, too, but what if, after being informed of the unreliability of water-perception... (shrink)

This is the 1992 Marquette Aquinas lecture, the fifty-third in a distinguished series sponsored by the Wisconsin Alpha Chapter of Phi Sigma Tau. Though presented as a lecture, it is clearly the outline of a project that draws upon Ernan McMullin's considerable knowledge of the history of the philosophy of science and his realistic assessment of contemporary scientific inquiry. His is a large canvas and he admittedly paints with wide brush strokes. His major thesis, contra the positivism that lingers in (...) some quarters, is that nothing other than a realist philosophy of science will enable one to make sense of contemporary natural science. A very literal reading of Aristotle leads him to distance himself from the Stagirite in certain respects, but McMullin's is fundamentally an Aristotelian analysis of science. To have science is not merely to know what is given in experience and codified in laws of nature, but to have an explanation of the given in terms of its proper causes. It is not enough to know that copper is malleable, conducts electricity, takes on a certain hue under such and such circumstances, and has a melting point of 1083 degrees centigrade. To have scientific knowledge of a material which has been used since antiquity is to know why it has these properties. Such knowledge is not obtained by simple observation, but is gained by the inference which leads to the postulation of an unobserved structure. McMullin believes that empiricists in the tradition of Bacon, Hume, and Mill are hard pressed to explain the inferential leap from observed effect to inferred cause. In passing he notes, "Though Bacon is trying very hard to separate himself from the Aristotelian tradition, one can still catch echoes of [Aristotle's] epagoge". Reviewing Mill's logic of science, McMullin observes that at the same time Mill was writing that causal relations hold only between observables, "the growing reliance of natural scientists on non-inductive inference to and from observables was leading to dramatic advances in fields like optics, chemistry and theory of gases".

The book consists of two major parts of three chapters apiece which are framed between: an introduction, which succinctly explains the primacy of the phenomenological dimension of depth, which concerns the distance between ourselves and things prior to any quantitative or inferential objectivization of experience; and a conclusion, which deals with some of the ethical implications stemming from our phenomenological construction of space. The focus of part 1 is to present the sense of the body as consisting of (...) an expressive topology based upon features such as mobility and other developmental factors, while part 2 demonstrates how our concept of place contributes to our sense of depth and orientation within a social environment. Forging such a sense of space in our dynamic relation to the world requires, according to Morris, that we eschew approaches which trade upon inferences drawn from a reduction of experience to an underlying order that exists prior to perception, and that we realize that it is we ourselves who actively constitute our sense of space. What this means, says Morris, following the example of ecological psychology, is that the emergence of perception is analogous to other phenomena that spontaneously arise from processes of self-organization. Morris cites Berkeley, whose dismantlement of dualism led the way to a better appreciation of the complete coordination of previously segregated facets of experience, as the forerunner of the intrinsic approach to the ordering of experience.

This essay develops an inferential account of model explanation, based on Mauricio Suárez’s inferential conception of scientific representation and Alisa Bokulich’s counterfactual account of model explanation. It is suggested that the fact that a scientific model can explain is essentially linked to how a modeler uses an established model to make various inferences about the target system on the basis of results derived from the model. The inference practice is understood as a two-step activity, with the first step (...) involving making counterfactual statements about the model itself and the second step involving making hypothetical statements transferring over claims derived from the model onto the target. To illustrate how this two-step activity proceeds, an agent-based simulation model is discussed. (shrink)

Phenomenal conservatism (PC) is the internalist view that non-inferential justification rests on appearances. PC’s advocates have recently argued that seemings are also required to explain inferential justification. The most general and developed view to this effect is Huemer (2016)’s theory of inferential seemings (ToIS). Moretti (2018) has shown that PC is affected by the problem of reflective awareness, which makes PC open to sceptical challenges. In this paper I argue that ToIS is afflicted by a version of (...) the same problem and it is thus hostage to inferential scepticism. I also suggest a possible response on behalf of ToIS’s advocates.

ABSTRACTThis paper provides a naturalistic account of inference. We posit that the core of inference is constituted by bare inferential transitions, transitions between discursive mental representations guided by rules built into the architecture of cognitive systems. In further developing the concept of BITs, we provide an account of what Boghossian [2014] calls ‘taking’—that is, the appreciation of the rule that guides an inferential transition. We argue that BITs are sufficient for implicit taking, and then, to analyse explicit taking, (...) we posit rich inferential transitions, which are transitions that the subject is disposed to endorse.

There is a felt difference between following an argument to its conclusion and keeping up with an argument in your judgments while failing to see how its conclusion follows from its premises. In the first case there’s what I’m calling an inferential seeming, in the second case there isn’t. Inferential seemings exhibit a cluster of functional and normative characteristics whose integration in one mental state is puzzling. Several recent accounts of inferring suggest inferential seemings play a significant (...) role in the process, but none provides a fully satisfactory understanding of inferential seemings themselves. In this paper I critically examine theoretical options on offer in the existing literature, then develop an alternative view. I discuss implications for recent debates about general principles governing inference, such as Fumerton’s Principle of Inferential Justification and Boghossian’s Taking Condition. (shrink)

A number of people have recently argued for a structural approach to accounting for the applications of mathematics. Such an approach has been called "the mapping account". According to this view, the applicability of mathematics is fully accounted for by appreciating the relevant structural similarities between the empirical system under study and the mathematics used in the investigation ofthat system. This account of applications requires the truth of applied mathematical assertions, but it does not require the existence of mathematical objects. (...) In this paper, we discuss the shortcomings of this account, and show how these shortcomings can be overcome by a broader view of the application of mathematics: the inferential conception. (shrink)

This paper critically examines currently influential transparency accounts of our knowledge of our own beliefs that say that self-ascriptions of belief typically are arrived at by “looking outward” onto the world. For example, one version of the transparency account says that one self-ascribes beliefs via an inference from a premise to the conclusion that one believes that premise. This rule of inference reliably yields accurate self-ascriptions because you cannot infer a conclusion from a premise without believing the premise, and so (...) you cannot infer from a premise that you believe the premise unless you do believe it. I argue that this procedure cannot be a source of justification, however, because one can be justified in inferring from p that q only if p amounts to strong evidence that q is true. This is incompatible with the transparency account because p often is not very strong evidence that you believe that p. For example, unless you are a weather expert, the fact that it will rain is not very strong evidence that you believe it will rain. After showing how this intuitive problem can be made precise, I conclude with a broader lesson about the nature of inferential justification: that beliefs, when justified, must be underwritten by beliefs, when justified, must be underwritten by evidential relationships between the facts or propositions which those beliefs represent.

Deflationists about truth hold that the function of the truth predicate is to enable us to make certain assertions we could not otherwise make. Pragmatists claim that the utility of negation lies in its role in registering incompatibility. The pragmatist insight about negation has been successfully incorporated into bilateral theories of content, which take the meaning of negation to be inferentially explained in terms of the speech act of rejection. We implement the deflationist insight in a bilateral theory by taking (...) the meaning of the truth predicate to be explained by its inferential relation to assertion. We combine this account of the meaning of the truth predicate with a new diagnosis of the Liar Paradox: its derivation requires the truth rules to preserve evidence, but these rules only preserve commitment. The result is a novel inferential deflationist theory of truth, which solves the Liar Paradox in a principled manner. We end by showing that our theory and simple extensions thereof have the resources to axiomatize the internal logic of several supervaluational hierarchies, including Cantini’s. This solves open problems of Halbach (2011) and Horsten (2011). (shrink)

We show that the conceptual distance between any two theories of first-order logic is the same as the generator distance between their Lindenbaum–Tarski algebras of concepts. As a consequence of this, we show that, for any two arbitrary mathematical structures, the generator distance between their meaning algebras (also known as cylindric set algebras) is the same as the conceptual distance between their first-order logic theories. As applications, we give a complete description for the distances between meaning (...) algebras corresponding to structures having at most three elements and show that this small network represents all the possible conceptual distances between complete theories. As a corollary of this, we will see that there are only two non-trivial structures definable on three-element sets up to conceptual equivalence (i.e., up to elementary plus definitional equivalence).

Most of our memories are inferential, so says Sven Bernecker in Memory: A Philosophical Study. I show that his account of inferentially remembering that p is too strong. A revision of the account that avoids the difficulty is proposed. Since inferential memory that p is memory that q (a proposition distinct from p) with an admixture of inference from one’s memory that q and a true thought one has that r, its analysis presupposes an adequate account of the (...) (presumably non-inferential) memory that q. Bernecker’s account of non-inferentially remembering that is shown to be inadequate. A remedy lies in strengthening the account by requiring the rememberer to have had prima facie justification to believe that q, any defeaters of which were misleading. (shrink)

In this paper we discuss the extent to which the very existence of substructural logics puts the Tarskian conception of logical systems in jeopardy. In order to do this, we highlight the importance of the presence of different levels of entailment in a given logic, looking not only at inferences between collections of formulae but also at inferences between collections of inferences—and more. We discuss appropriate refinements or modifications of the usual Tarskian identity criterion for logical systems, and propose an (...) alternative of our own. After that, we consider a number of objections to our account and evaluate a substantially different approach to the same problem. (shrink)

This paper defends an inferential conception of scientific representation. It approaches the notion of representation in a deflationary spirit, and minimally characterizes the concept as it appears in science by means of two necessary conditions: its essential directionality and its capacity to allow surrogate reasoning and inference. The conception is defended by showing that it successfully meets the objections that make its competitors, such as isomorphism and similarity, untenable. In addition the inferential conception captures the objectivity of the (...) cognitive representations used by science, it sheds light on their truth and completeness, and it explains the source of the analogy between scientific and artistic modes of representation.

Starting from the notions of q-entailment and p-entailment, a two-dimensional notion of entailment is developed with respect to certain generalized q-matrices referred to as B-matrices. After showing that every purely monotonic singleconclusion consequence relation is characterized by a class of B-matrices with respect to q-entailment as well as with respect to p-entailment, it is observed that, as a result, every such consequence relation has an inferentially four-valued characterization. Next, the canonical form of B-entailment, a two-dimensional multiple-conclusion notion of entailment based (...) on B-matrices, is introduced, providing a uniform framework for studying several different notions of entailment based on designation, antidesignation, and their complements. Moreover, the two-dimensional concept of a B-consequence relation is defined, and an abstract characterization of such relations by classes of B-matrices is obtained. Finally, a contribution to the study of inferential many-valuedness is made by generalizing Suszko’s Thesis and the corresponding reduction to show that any B-consequence relation is, in general, inferentially four-valued.

I propose and defend the conjecture that what explains why Gettiered subjects fail to know is the fact that their justified true belief depends essentially on unknown propositions. The conjecture follows from the plausible principle about inference in general according to which one knows the conclusion of one’s inference only if one knows all the premises it involves essentially.

The aim of the paper is to explore the interrelation between persuasion tactics and properties of speech acts. We investigate two types of arguments ad: ad hominem and ad baculum. We show that with both of these tactics, the structures that play a key role are not inferential, but rather ethotic, i.e., related to the speaker’s character and trust. We use the concepts of illocutionary force and constitutive conditions related to the character or status of the speaker in order (...) to explain the dynamics of these two techniques. In keeping with the research focus of the Polish School of Argumentation, we examine how the pragmatic and rhetorical aspects of the force of ad hominem and ad baculum arguments exploit trust in the speaker’s status to influence the audience’s cognition.

Scientific models need to be investigated if they are to provide valuable information about the systems they represent. Surprisingly, the epistemological question of what enables this investigation has hardly been investigated. Even authors who consider the inferential role of models as central, like Hughes or Bueno and Colyvan, content themselves with claiming that models contain mathematical resources that provide inferential power. We claim that these notions require further analysis and argue that mathematical formalisms contribute to this inferential (...) role. We characterize formalisms, illustrate how they extend our mathematical resources, and highlight how distinct formalisms offer various inferential affordances. (shrink)

In philosophical semantics, a distinction has been proposed between inferential and referential lexical semantic competence. The former accounts for the relationship of words to the world, the latter for the relationship of words among themselves. Recent neuroscience research suggests that the distinction might be actually neurally implemented. That is, that inferential and referential abilities might be underpinned by two functionally independent cognitive architectures, with partly different neural realizations. This hypothesis is consistent with brain patient data, supporting the notion (...) of a functional double dissociation between inferential and referential abilities, and with neuroscience data, suggesting that inferential and referential abilities are underpinned by at least partly different regions of the human brain. The principal aim of this article is to provide the first comprehensive and critical review of the empirical evidence in favour of such hypothesis. (shrink)

We develop a novel solution to the negation version of the Frege-Geach problem by taking up recent insights from the bilateral programme in logic. Bilateralists derive the meaning of negation from a primitive *B-type* inconsistency involving the attitudes of assent and dissent. Some may demand an explanation of this inconsistency in simpler terms, but we argue that bilateralism’s assumptions are no less explanatory than those of *A-type* semantics that only require a single primitive attitude, but must stipulate inconsistency elsewhere. Based (...) on these insights, we develop a version of B-type expressivism called *inferential expressivism*. This is a novel semantic framework that characterises meanings by inferential roles that define which *attitudes* one can *infer* from the use of terms. We apply this framework to normative vocabulary, thereby solving the Frege-Geach problem generally and comprehensively. Our account moreover includes a semantics for epistemic modals, thereby also explaining normative terms under epistemic modals. (shrink)

In a recent article, Shaw contrasts his own supposed good behaviour, as that of a self-proclaimed “social distance warrior” with the alleged rude behaviour of one of his relatives, Jack, at social events in the former’s house in Scotland in the early stages of the COVID-19 pandemic. He does so to illustrate and support his claims that it was wrong and rude to fail to comply with the governmental advice regarding social distancing because we had a responsibility “to minimize (...) risk” and not wrong nor rude to challenge and cajole those people who failed to do so. This article shows that his claims are contestable. It suggests that his own behaviour was no better than Jack’s. (shrink)

Inferential erotetic logic and inquisitive semantics give accounts of questions and model various aspects of questioning. In this paper we concentrate upon connections between inquisitiveness, being the core concept of INQ, and question raising, characterized in IEL by means of the concepts of question evocation and erotetic implication. We consider the basic system InqB of INQ, remain at the propositional level and show, inter alia, that: a disjunction of all the direct answers to an evoked question is always inquisitive; (...) a formula is inquisitive if, and only if it evokes a yes–no question whose affirmative answer expresses a possibility for the formula; inquisitive formulas evoke questions whose direct answers express all the possibilities for the formulas, and each question erotetically implies a question whose direct answers express the possibilities for the direct answers to the implying question.

This paper considers whether an analogy between distance and dissimilarlity supports the thesis that degree of dissimilarity is distance in a metric space. A straightforward way to justify the thesis would be to define degree of dissimilarity as a function of number of properties in common and not in common. But, infamously, this approach has problems with infinity. An alternative approach would be to prove representation and uniqueness theorems, according to which if comparative dissimilarity meets certain qualitative conditions, (...) then it is representable by distance in a metric space. I will argue that this approach faces equally severe problems with infinity. (shrink)

The intention of this project is to argue theoretically for, and exemplify through critical and historical analysis, the interrelatedness of discourses on scale, distance, identification and doubling in the cinema. The link between the first two terms (scale and distance) and the latter two (identification and doubling) is implicit in the title, and its unfolding constitutes the project: for instance, the closer one comes, the deeper identification is likely to be, and the greater the likelihood that what is (...) apparently 'there' will impose itself as also 'here', existing both inside and outside the viewing psyche, which becomes double, and whose doubling may either become explicit or remain implicit in the text. Along with its collapsing of interiority/exteriority distinctions, doubling reveals the reversibility and ambiguity of scale, as what is 'there' could just as well have been situated 'here'. The book contains analyses of a wide variety of films, including Citizen Kane, The Double Life of Veronique, The Great Gatsby, Gilda, Vertigo and Wings of Desire. (shrink)

Many conditionals seem to convey the existence of a link between their antecedent and consequent. We draw on a recently proposed typology of conditionals to argue for an old philosophical idea according to which the link is inferential in nature. We show that the proposal has explanatory force by presenting empirical results on the evidential meaning of certain English and Dutch modal expressions.

This is a critical discussion of Jerry Fodor and Ernie Lepore's "Holism". The paper questions the existence of a slippery slope from some inferential liaisons are constitutive of meaning' to all inferential liaisons are constitutive of meaning'. "Interalia", it defends the existence of an analytic/synthetic distinction.

We perform an experimental investigation using a dictator game in which individuals must make a moral decision —to give or not to give an amount of money to poor people in the Third World. A questionnaire in which the subjects are asked about the reasons for their decision shows that, at least in this case, moral motivations carry a heavy weight in the decision: the majority of dictators give the money for reasons of a consequentialist nature. Based on the results (...) presented here and of other analogous experiments, we conclude that dicator behavior can be understood in terms of moral distance rather than social distance and that it systematically deviates from the egoism assumption in economic models and game theory.

To justify inductive inference and vanquish classical skepticisms about human memory, external world realism, etc., Richard Fumerton proposes his “inferential internalism,” an epistemology whereby humans ‘see’ by Russellian acquaintance Keynesian probable relations (PRs) between propositions. PRs are a priori necessary relations of logical probability, akin to but not reducible to logical entailments, such that perceiving a PR between one’s evidence E and proposition P of unknown truth value justifies rational belief in P to an objective degree. A recent critic (...) of inferential internalism is Alan Rhoda, who questions its psychological plausibility. Rhoda argues that in order to see necessary relations between propositions E and P, one would need acquaintance with too many propositions at once, since our evidence E is often complex. In this paper, I criticize Rhoda’s implausibility objection as too quick. Referencing the causal status effect (CSE) from psychology, I argue that some of the complex features of evidence E contribute to our type-categorizing it as E-type, and thus we do not need to ‘see’ all of the complex features when we see the PR between E and P. My argument leaves unchanged Fumerton’s justificatory role for the PR, but enhances its psychological plausibility. (shrink)

Inferential Internalists accept the Principle of Inferential Justification (PIJ), according to which one has justification for believing P on the basis of E only if one has justification for believing that E makes probable P. Richard Fumerton has defended PIJ by appeal to examples, and recently Adam Leite has argued that this principle is supported by considerations regarding the nature of responsible belief. In this paper, I defend a form of externalism against both arguments. This form of externalism (...) recognizes what I call the phenomenon of reflective defeat: if one is justified in not believing that E makes probable P, then this defeats whatever justification one has for believing P upon the basis of E. I argue that this modified version of externalism has the virtue of accommodating the intuitions that motivate internalism, without the cost of the vicious regress that makes internalism so unattractive.

It is commonly thought that the requirements of inferential justification are such that necessarily the process of inferentially justifying a belief will come to an end. But, If this is so, We should be able to pick out those requirements of justification which necessitate an end to the justification process. Unfortunately, Although there is nearly unanimous agreement as to the need for such an end, It is by no means clear which particular requirements of justification impose this need. I (...) examine and criticize several seemingly plausible ways of showing that regresses of inferential justification are impossible and then propose two requirements of inferential justification which, I argue, Are sufficient to show the impossibility.

탈진실이라는 용어는 최근 등장한 새로운 개념어이다. 그럼에도 불구하고 우리는 이 용어가 등장하는 생활환경을 낯설게 생각하지 않을 정도로 탈진실이라는 용어에 이미 익숙하다. 일명 가짜 뉴스나 데이터 조작으로 발생한 탈진실의 상황은 진실을 찾고 추구하려 시도했던 지식의 탑을 어떤 방식으로 조롱할 수 있는지 여실히 보여주었다. 이 글은 탈진실에 대한 기존의 분석들을 소개하고 탈진실의 원인으로 꼽히고 있는 논점에 대해 다시 살피고자 한다. 그로부터 탈진실에 대한 개념적 정의가 정확하게 탈진실이 무엇인지 해명하지 못한다고 지적할 것이다. 또 탈진실이 발생한 배경으로 지목받는 해체주의와 푸코의 지식 담론에 대한 논의들이 (...) 실제로 탈진실과는 무관한 문제임을 밝힐 것이다. 그로부터 이 글은 푸코의 진실론에 기반하여 탈진실의 개념은 푸코의 사유에서 찾을 수 없고 오히려 반푸코적 현상이라는 점을 규명할 것이다. 마지막으로 푸코의 진실론(parrhêsia)을 통해 탈진실의 문제를 해소할 수 있는 방안을 모색할 것이다.

We outline a framework for analyzing episodes from the history of science in which the application of mathematics plays a constitutive role in the conceptual development of empirical sciences. Our starting point is the inferential conception of the application of mathematics, recently advanced by Bueno and Colyvan. We identify and discuss some systematic problems of this approach. We propose refinements of the inferential conception based on theoretical considerations and on the basis of a historical case study. We demonstrate (...) the usefulness of the refined, dynamical inferential conception using the well-researched example of the genesis of general relativity. Specifically, we look at the collaboration of the physicist Einstein and the mathematician Grossmann in the years 1912--1913, which resulted in the jointly published ``Outline of a Generalized Theory of Relativity and a Theory of Gravitation,'' a precursor theory of the final theory of general relativity. In this episode, an independently developed mathematical theory, the theory of differential invariants and the absolute differential calculus, was applied in the process of physical theorizing aiming at finding a relativistic theory of gravitation. We argue that the dynamical inferential conception not only provides a natural framework to describe and analyze this episode, but it also generates new questions and insights. We comment on the mathematical tradition on which Grossmann drew, and on his own contributions to mathematical theorizing. We argue that the dynamical inferential conception allows us to identify both the role of heuristics and of mathematical resources as well as the systematic role of problems and mistakes in the reconstruction of episodes of conceptual innovation and theory change.

Unconscious logical inference seems to rely on the syntactic structures of mental representations (Quilty-Dunn & Mandelbaum 2018). Other transitions, such as transitions using iconic representations and associative transitions, are harder to assimilate to syntax-based theories. Here we tackle these difficulties head on in the interest of a fuller taxonomy of mental transitions. Along the way we discuss how icons can be compositional without having constituent structure, and expand and defend the “symmetry condition” on Associationism (the idea that associative links and (...) transitions are perfectly symmetric). In the end, we show how a BIT (“bare inferential transition”) theory can cohabitate with these other non-inferential mental transitions. (shrink)

Reliability theories of epistemic justification face three main objections: the generality problem, the demon-world (or brain-in-a-vat) counterexample, and the clairvoyant-powers counterexample. In Perception and Basic Beliefs(Oxford 2009), Jack Lyons defends reliabilism at length against the clairvoyant powers case. He argues that the problem arises due to a laxity about the category of basic beliefs, and the difference between inferential and non-inferential justification. Lyons argues reliabilists must pay more attention to architecture. I argue this isn’t necessarily so. What really (...) matters for understanding and solving the case involves paying closer attention to the origins of our belief forming capacities, both inferential and non-inferential. Reliabilists should make origins matter more. (shrink)

We outline a pragmatic-normative understanding of logic as a discipline that is completely anchored in the sphere of action, rules, means and ends: We characterize inferring as a speech act which is in need of regulation and we connect inferential rules with consequence relations. Furthermore, we present a scenario which illustrates how one actually assesses or can in principle assess the quality of logical rules with respect to justificatory questions. Finally, we speculate on the origin of logical rules as (...) a means of supporting our practice of inferring. (shrink)
