Inductive logic would be the logic of arguments that are not valid, but nevertheless justify belief in something like the way in which valid arguments would. Maybe we could describe it as the logic of “almost valid” arguments. There is a sort of transitivity to valid arguments. Valid arguments can be chained together to form arguments and such arguments are themselves valid. One wants to distinguish the “almost valid” arguments by noting that chains of “almost valid” arguments are weaker than (...) the links that form them. But it is not clear that this is so. I have an apparent counterexample the claim. Though: as is typical in these sorts of situations, it is hard to tell where the problem lies. (shrink)

The reduction of grounding to causation, or each to a more general relation of which they are species, has sometimes been justified by the impressive inferential capacity of structural equation modelling, causal Bayes nets, and interventionist causal modelling. Many criticisms of this assimilation focus on how causation is inadequate for grounding. Here, I examine the other direction: how treating grounding in the image of causation makes the resulting view worse for causation. The distinctive features of causal modelling that make (...) this connection appealing are distorted beyond use by forcing them to fit onto grounding. The very inferential strength that makes causation attractive is only possible because of a narrow construal of what counts as a causal relation; as soon as that broadens, the inferential capacity markedly diminishes. Making causation suitable for application to grounding spoils what was appealing about causation for this task in the first place. However, grounding need not appeal to causation: causal modelling does not have exclusive claim to structural equation modeling or other formal techniques of modelling structure. I offer a case in favour of a different kind of metaphysical frugality, which tend towards narrow, more restrictive construals of relations like causation or grounding, because then each relation behaves more homogenously. This more homogenous behavior delivers stronger inferential power per relation even though there may be more relations to which one is committed. (shrink)

This paper advances an approach to relevance grounded on patterns of material inference called argumentation schemes, which can account for the reconstruction and the evaluation of relevance relations. In order to account for relevance in different types of dialogical contexts, pursuing also non-cognitive goals, and measuring the scalar strength of relevance, communicative acts are conceived as dialogue moves, whose coherence with the previous ones or the context is represented as the conclusion of steps of material inferences. Such inferences are (...) described using argumentation schemes and are evaluated by considering 1) their defeasibility, and 2) the acceptability of the implicit premises on which they are based. The assessment of both the relevance of an utterance and the strength thereof depends on the evaluation of three interrelated factors: 1) number of inferential steps required; 2) the types of argumentation schemes involved; and 3) the implicit premises required.

Reasoning from negative evidence takes place where an expected outcome is tested for, and when it is not found, a conclusion is drawn based on the significance of the failure to find it. By using Gricean maxims and implicatures, we show how a set of alternatives, which we call a paradigm, provides the deep inferential structure on which reasoning from lack of evidence is based. We show that the strength of reasoning from negative evidence depends on how the (...) arguer defines his conclusion and what he considers to be in the paradigm of negated alternatives. If we negate only two of the several possible alternatives, even if they are the most probable, the conclusion will be weak. However, if we deny all possible alternatives, the reasoning will be strong, and even in some cases deductively valid. (shrink)

This paper brings together Thompson's naive action explanation with interventionist modeling of causal structure to show how they work together to produce causal models that go beyond current modeling capabilities, when applied to specifically selected systems. By deploying well-justified assumptions about rationalization, we can strengthen existing causal modeling techniques' inferential power in cases where we take ourselves to be modeling causal systems that also involve actions. The internal connection between means and end exhibited in naive action explanation has a (...) modal strength like that of distinctively mathematical explanation, rather than that of causal explanation. Because it is stronger than causation, it can be treated as if it were merely causal in a causal model without thereby overextending the justification it can provide for inferences. This chapter introduces and demonstrate the usage of the Rationalization condition in causal modeling, where it is apt for the system(s) being modeled, and to provide the basics for incorporating R variables into systems of variables and R arrows into DAGs. Use of the Rationalization condition supplements causal analysis with action analysis where it is apt. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Appearance and Explanation: Phenomenal Explanationism in Epistemology by Kevin McCain and Luca MorettiCaleb EstepMcCAIN, Kevin and Luca Moretti. Appearance and Explanation: Phenomenal Explanationism in Epistemology. Oxford: Oxford University Press, 2021. iv + 195 pp. Cloth, $70.00Since its beginning, phenomenal conservatism (PC) has grown rapidly in popularity as a theory of epistemic justification. In Appearance and Explanation, McCain and Moretti develop out of PC a new theory of justification (...) that they call phenomenal explanationism (PE). Their goal is to integrate PC with explanationism—the view that epistemic justification comes from the best explanation—thereby creating PE as a hybrid theory. They ambitiously contend that PE captures the same basic intuitions as PC but is better equipped to handle epistemic phenomena as a whole, troubling objections to PC (and foundationalism in general), and skeptical [End Page 354] arguments. The book is comprised of seven chapters. This review will emphasize the first four.In chapter 1, the authors discuss what PC is and its merits. PC is the idea that "we should grant things to be the way they appear [or seem] to be, unless we have reason to doubt" our seemings. They point out some of the benefits of PC as perceived by its followers: It "provide[s] widespread epistemic practices with a rationale," "it offers a unified account of non-inferential justification for beliefs of very different types," "it constitutes the basis of fallible foundationalism," and has a strong "antiskeptical bite."In chapter 2, McCain and Moretti argue that PC is not sufficient to account even for noninferential justification. First, they argue, PC gives an insufficient explanation of the no-defeater condition. The no-defeater condition is the "unless we have reason to doubt" clause built into PC. PC does not explain why or how S's reason to doubt "interacts with S's seeming that e in such a way as to diminish S's non-inferential justification for believing p." Second, if the power of seemings to justify comes from the seemings themselves, then the seemings become unstable once the subject becomes aware of them. The upshot of this is that if seemings are sufficient for justification, then some beliefs that should not be justified would have justification.In chapter 3, the authors begin to elaborate on their view. The authors distinguish between mere seemings, paired appearances, and presentational appearances to show how appearances can have varying degrees of justificatory power. Seemings and appearances are used in a roughly synonymous way. Mere seemings are lacking in both sensations and presentational phenomenology, hence they provide a very weak form of justification. Paired appearances have sensations but not presentational phenomenology. They have greater justificatory strength than mere seemings but less strength than presentational appearances. Presentational appearances produce the strongest justification and include both sensations and presentational phenomenology. The big payoff from these distinctions is that they show how different appearances can produce varying strengths of justification.In chapter 4, Moretti and McCain first outline their version of explanationism, which is evidentialist in character. It is as follows: "Believing p is justified for S at t if and only if at t:(1). S has total evidence, E;(2). either (i) p is the best (sufficiently good) explanation of e (where e is a subset of E), or (ii) p is an explanatory consequence of the best (sufficiently good) explanation of e (where p is such an explanatory consequence if and only if the relevant explanation of e would provide an explanation of p's truth that is significantly better than the explanation it would provide of ~ p's truth);(3). it is not the case that p fails to satisfy (i) and (ii) with respect to e because of the additional evidence included in E." [End Page 355]Next, the authors merge explanationism with PC as understood through the threefold division of appearances given in chapter 3. The result is that appearances or seemings are necessary and sufficient for a subject to have evidence, but the subject is justified in believing some proposition p only because p is the best explanation of the evidence. Appearances contribute to epistemic justification because as evidence they regulate the capacity... (shrink)

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)

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. (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. (shrink)

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)

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. (shrink)

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.

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 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)

The purpose of this paper is twofold: -/- 1) to highlight the widely ignored but fundamental problem of ‘superpopulations’ for the use of inferential statistics in development studies. We do not to dwell on this problem however as it has been sufficiently discussed in older papers by statisticians that social scientists have nevertheless long chosen to ignore; the interested reader can turn to those for greater detail. -/- 2) to show that descriptive statistics both avoid the problem of superpopulations (...) and can be a powerful tool when used correctly. A few examples are provided. -/- The paper ends with considerations of some reasons we think are behind the adherence to methods that are known to be inapplicable to many of the types of questions asked in development studies yet still widely practiced.

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)

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)

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)

This paper aims to meet an objection that has been raised against structural empiricism known as the “loss of reality objection.” I argue that an inferential approach to scientific representation allows the structural empiricist to account for the representation of phenomena by data models and ensures that such a representation is not arbitrary. By the notions of immersion, derivation, and interpretation, I show how data models are able to represent phenomena in a non-arbitrary manner. I conclude this paper with (...) a programmatic outline of a view that arises from the theses defended throughout the article and that I would like to call “semantic structuralism.”. (shrink)

Richard Holton has presented an important criticism of two prominent accounts of action, a criticism that employs a notion of strength of will. Holton claims that these well-known accounts of action cannot explain cases in which an agent adheres to the dictates of a previous resolution in spite of a persistent desire to the contrary. In this chapter, I present an explanation and defense of Holton’s criticism of these accounts of action, and then I argue that while Holton highlights (...) a crucial deficiency in both, his own explanation of strength of will is problematic.

Logical inferentialism maintains that the formal rules of inference fix the meanings of the logical terms. The categoricity problem points out to the fact that the standard formalizations of classical logic do not uniquely determine the intended meanings of its logical terms, i.e., these formalizations are not categorical. This means that there are different interpretations of the logical terms that are consistent with the relation of logical derivability in a logical calculus. In the case of the quantificational logic, the categoricity (...) problem is generated by the finite nature of the standard calculi and one direction in which it can be solved is to strengthen the deductive systems by adding infinitary rules (such as the ω-rule), i.e., to construct a full formalization. Another main direction is to provide a natural semantics for the standard rules of inference, i.e., a semantics for which these rules are categorical. My aim in this paper is to analyze some recent approaches for solving the categoricity problem and to argue that a logical inferentialist should accept the infinitary rules of inference for the first order quantifiers, since our use of the expressions “all” and “there is” leads us beyond the concrete and finite reasoning, and human beings do sometimes employ infinitary rules of inference in their reasoning.

I introduce the Displaced Perception Model of Introspection developed by Dretske which treats introspection of phenomenal states as inferential and criticize it.

Our pains can be more or less intense, our mental imagery can be more or less vivid, our perceptual experiences can be more or less striking. These degrees of intensity of conscious experiences are all manifestations of a phenomenal property I call mental strength. In this article, I argue that mental strength is a domain-general phenomenal magnitude; in other words, it is a phenomenal quantity shared by all conscious experiences that explains their degree of felt intensity. Mental (...) class='Hi'>strength has been largely overlooked in favor of mental states’ type, representational contents, domain-specific phenomenology, or processes such as attention. Considering mental strength in our reflections about the mind illuminates debates about the relation of representational contents and phenomenal character, and it also helps address questions about the structure and functions of consciousness. Mental strength provides a unifying construct to model what is shared in the phenomenology of different types of conscious experiences. (shrink)

A metainference is usually understood as a pair consisting of a collection of inferences, called premises, and a single inference, called conclusion. In the last few years, much attention has been paid to the study of metainferences—and, in particular, to the question of what are the valid metainferences of a given logic. So far, however, this study has been done in quite a poor language. Our usual sequent calculi have no way to represent, e.g. negations, disjunctions or conjunctions of inferences. (...) In this paper we tackle this expressive issue. We assume some background sentential language as given and define what we call an inferential language, that is, a language whose atomic formulas are inferences. We provide a model-theoretic characterization of validity for this language—relative to some given characterization of validity for the background sentential language—and provide a proof-theoretic analysis of validity. We argue that our novel language has fruitful philosophical applications. Lastly, we generalize some of our definitions and results to arbitrary metainferential levels. (shrink)

Jerry Fodor and Ernie Lepore have argued that inferential roles are not compositional. It is unclear, however, whether the theories at which they aim their objection are obliged to meet the strong compositionality requirement they have in mind. But even if that requirement is accepted, the data they adduce can in fact be derived from an inferential-role theory that meets it. Technically this is trivial, but it raises some interesting objections turning on the issue of the generality of (...) inferential roles. I explain how those objections can be met. Whether Fodor’s and Lepore’s strong compositionality requirement is justified or not, then, inferential-role theories do not have the problem that they claim to have identified. (shrink)

In this paper, I flesh out an account of the inferential basing relation using a theory about how humans reason: the mental models theory. I critically assess some of the notions that are used by that theory to account for inferential phenomena. To the extent that the mental models theory is well confirmed, that account of basing would be motivated on empirical grounds. This work illustrates how epistemologists could offer explications of the basing relation which are more detailed (...) and less empirically risky. (shrink)

While the situationist challenge has been prominent in philosophical literature in ethics for over a decade, only recently has it been extended to virtue epistemology . Alfano argues that virtue epistemology is shown to be empirically inadequate in light of a wide range of results in social psychology, essentially succumbing to the same argument as virtue ethics. We argue that this meeting of the twain between virtue epistemology and social psychology in no way signals the end of virtue epistemology, but (...) is rather a boon to naturalized virtue epistemology. We use Gird Gigerenzer’s models for bounded rationality (2011) to present a persuasive line of defense for virtue epistemology, and consider prospects for a naturalized virtue epistemology that is supported by current research in psychology.

Opinions are rarely binary; they can be held with different degrees of conviction, and this expanded attitude spectrum can affect the influence one opinion has on others. Our goal is to understand how different aspects of influence lead to recognizable spatio-temporal patterns of opinions and their strengths. To do this, we introduce a stochastic spatial agent-based model of opinion dynamics that includes a spectrum of opinion strengths and various possible rules for how the opinion strength of one individual affects (...) the influence that this individual has on others. Through simulations, we find that even a small amount of amplification of opinion strength through interaction with like-minded neighbors can tip the scales in favor of polarization and deadlock.

The paper discusses Saul Kripke's Normativity Argument against semantic dispositionalism: it criticizes the orthodox interpretation of the argument, defends an alternative reading and argues that, contrary to what Kripke himself seems to have been thinking, the real point of the Normativity Argument is not that meaning is normative. According to the orthodox interpretation, the argument can be summarized as follows: (1) it is constitutive of the concept of meaning that its instances imply an ought, but (2) it is not constitutive (...) of the concept of a disposition that dispositions imply an ought, hence (3) no dispositional analysis of meaning can work. According to my alternative reading, the point of the argument is another one, namely that while (1) dispositionalism is committed to the thesis that speakers have non-inferential knowledge of their unmanifested linguistic dispositions, (2) speakers, as a matter of fact, do not have such a knowledge. A point that is in principle independent from the issue of the normativity of meaning. (shrink)

This paper investigates the emotive (or expressive) meaning of words commonly referred to as “loaded” or “emotive,” which include slurs, derogative or pejorative words, and ethical terms. We claim that emotive meaning can be reinterpreted from a pragmatic and argumentative perspective, which can account for distinct aspects of ethical terms, including the possibility of being modified and its cancellability. Emotive meaning is explained as a defeasible and automatic or automatized evaluative and intended inference commonly associated with the use of specific (...) terms, which can be represented and assessed considering its logical structure and its defeasibility conditions. This automatic inference is conceived as part of the connotation of an ethical term, and is not necessarily stable. By means of quasi-definitions, it is possible to modify the emotive meaning while maintaining the descriptive one, automaticizing the inferences drawn from an ethical word. Through examples drawn from the recent US presidential campaign, we show how re-contextualization and emotive contexts can affect emotive meaning. (shrink)

Classical acquaintance theory is any version of classical foundationalism that appeals to acquaintance in order to account for non-inferential justification. Such theories are well suited to account for a kind of infallible non-inferential justification. Why am I justified in believing that I’m in pain? An initially attractive (partial) answer is that I’m acquainted with my pain. But since I can’t be acquainted with what isn’t there, acquaintance with my pain guarantees that I’m in pain. What’s less clear is (...) whether, given classical acquaintance theory, it’s possible to have non-inferential justification to believe something false. Classical acquaintance theorists try to make room for such a possibility, but I argue that the attempts of Richard Fumerton, Ali Hasan, and Evan Fales are inadequate. I’ll focus on introspective justification, but similar issues arise for a priori justification as well. (shrink)

This paper argues for the view that metaphors are assertions by locating metaphor within our social discursive practices of asserting and inferring. The literal and the metaphorical differ not in the stating of facts nor in the representation of states of affairs but in the kind of inferential involvements they have and the normative score-keeping practices within which the inferential connections are articulated. This inferentialist based account of metaphor is supplemented by insights from accommodation theory. The account is (...) significant for our understanding of both metaphor‟s figurativeness and cognitive content. (shrink)

In this paper, I present the fundamental ideas of a new theory of justification strength. This theory is based on the epistemological approach to argumentation. Even the thesis of a valid justification can be false for various reasons. The theory outlined here identifies such possible errors. Justification strength is equated with the degree to which such possible errors are excluded. The natural expression of this kind of justification strength is the (rational) degree of certainty of the belief (...) in the thesis. (shrink)

We propose a typology of representational artifacts for health care and life sciences domains and associate this typology with different kinds of formal ontology and logic, drawing conclusions as to the strengths and limitations for ontology in a description logics framework. The four types of domain representation we consider are: (i) lexico-semantic representation, (ii) representation of types of entities, (iii) representations of background knowledge, and (iv) representation of individuals. We advocate a clear distinction of the four kinds of representation in (...) order to provide a more rational basis for using ontologies and related artifacts to advance integration of data and enhance interoperability of associated reasoning systems. We highlight the fact that only a minor portion of scientifically relevant facts in a domain such as biomedicine can be adequately represented by formal ontologies as long as the latter are conceived as representations of entity types. In particular, the attempt to encode default or probabilistic knowledge using ontologies so conceived is prone to produce unintended, erroneous models. (shrink)

My main aim at this paper is to present Lewis Carrol’s Paradox on the justification of logical principles inasmuch as some attempts of solving it. This is important because if there are basic logical principles, it also seems necessary to exist some justification for them. By considering some observations from Ryle, Devitt and Kripke about the theme, we intend to briefly display their theories and their core critics among themselves and, mainly, the critics against adoption theory.

This paper attempts to address the question what logical strength theories of truth have by considering such questions as: If you take a theory T and add a theory of truth to it, how strong is the resulting theory, as compared to T? It turns out that, in a wide range of cases, we can get some nice answers to this question, but only if we work in a framework that is somewhat different from those usually employed in discussions (...) of axiomatic theories of truth. These results are then used to address a range of philosophical questions connected with truth, such as what Tarski meant by "essential richness" and the so-called conservativeness argument against deflationism. -/- This draft dates from about 2009, with some significant updates having been made around 2011. Around then, however, I decided that the paper was becoming unmanageable and that I was trying to do too many things in it. I have therefore exploded the paper into several pieces, which will be published separately. These include "Disquotationalism and the Compositional Principles", "The Logical Strength of Compositional Principles", "Consistency and the Theory of Truth", and "What Is Essential Richness?" You should probably read those instead, since this draft remains a bit of a mess. Terminology and notation are inconsistent, and some of the proofs aren't quite right. So, caveat lector. I make it public only because it has been cited in a few places now. (shrink)

We commonly say that some evidence supports a hypothesis or that some premise evidentially supports a conclusion. Both internalists and externalists attempt to analyze this notion of evidential support, and the primary purpose of this paper is to argue that reliabilist and proper functionalist accounts of this relation fail. Since evidential support is one component of inferential justification, the upshot of this failure is that their accounts of inferential justification also fail. In Sect. 2, I clarify the evidential (...) support relation. In Sects. 3–5, I subject reliabilist and proper functionalist accounts of evidential support to various counterexamples. In Sect. 6, I show that the most promising ways to address these counterexamples aren’t very promising. (shrink)

In this paper I provide empirical and theoretical considerations in favor of a non-inferential view of speech comprehension. On the view defended, we typically comprehend speech by perceiving or grasping apparently conveyed meanings directly rather than by inferring them from, say, linguistic principles and perceived phonemes. “Speech” is here used in the broad sense to refer not only to verbal expression, but also written messages, including Braille, and conventional signs and symbols, like emojis, a stop sign or a swastika. (...) Along the way I define what I mean by ‘inference’ and provide an account of what it means to say that we perceive apparently conveyed meanings. (shrink)

Hume’s understanding of sympathy in section 2.1.11 of the Treatise—that it is a mental mechanism by means of which one sentient being can come to share the psychological states of another—has a particularly interesting implication. What the sympathizer receives, according to this definition, is the passing psychological “affection” that the object of his sympathy was experiencing at the moment of observation. Thus the psychological connection produced by Humean sympathy is not between the sympathizer and the “other” as a “whole person” (...) existing through time, but between the sympathizer and the other’s current mental state, detached from his or her diachronic psychological life. Some commentators profess themselves dissatisfied with the impersonality of this “limited sympathy”. John Bricke, for example, argues that the Humean sympathizer sympathizes with “atomistically rendered desires of some individual who is, thus far, of no further concern,” while Philip Mercer writes more bluntly that Hume’s definition omits the “practical concern for the other” that is the essence of sympathy’s contribution to moral psychology.

This paper deals with Peirce’s understanding of perceptual judgment, relating it to the conditions for the use of language defined by Michael Dummett. Namely, drawing on Dummett’s requirement for harmony between descriptive and evaluative aspects of our linguistic practice, we will try to give an interpretation of Peirce’s view of perception that implies rejecting the idea that the formation of a perceptual judgment has an inferential structure. On the other hand, since it is, in Peirce’s opinion, the structure of (...) abductive inference, this approach should enable us to draw some conclusions related to abduction in general. (shrink)

Applying a theory of psychological modularity, I argue for a theory of defeasibility conditions for the epistemic justification of perceptual beliefs. My theory avoids the extremes of holism (e.g., coherentism and confirmation holism) and of foundationalist theories of non-inferential justification.

The question I address in this paper is what is it exactly for desires to possess a certain strength. And my aim is twofold. First, I argue for a pluralistic account of desire strength. On this view, there are several dimensions along which desires possess greater or lesser strength, and none of them is intrinsically privileged. My second aim is to highlight some time-based properties of desires, recurrence and persistence. Both desires’ degree of persistence across time and (...) their rate of episodic recurrence are, I argue, further dimensions of desire strength. (shrink)
