We present a Kripke model for Girard's Linear Logic (without exponentials) in a conservative fashion where the logical functors beyond the basic lattice operations may be added one by one without recourse to such things as negation. You can either have some logical functors or not as you choose. Commutatively and associatively are isolated in such a way that the base Kripke model is a model for noncommutative, nonassociative Linear Logic. We also extend the logic by adding a coimplication operator, (...) similar to Curry's subtraction operator, which is resituated with Linear Logic's contensor product. And we can add contraction to get nondistributive Relevance Logic. The model rests heavily on Urquhart's representation of nondistributive lattices and also on Dunn's Gaggle Theory. Indeed, the paper may be viewed as an investigation into nondistributive Gaggle Theory restricted to binary operations. The valuations on the Kripke model are three valued: true, false, and indifferent. The lattice representation theorem of Urquhart has the nice feature of yielding Priestley's representation theorem for distributive lattices if the original lattice happens to be distributive. Hence the representation is consistent with Stone's representation of distributive and Boolean lattices, and our semantics is consistent with the Lemmon-Scott representation of modal algebras and the Routley-Meyer semantics for Relevance Logic.

Our aim in this paper is to argue that empathy is an intellectual virtue. Empathy enables agents to gain insight into other people’s emotions and beliefs. The agent who possesses this trait is: (i) driven to engage in acts of empathy by her epistemic desires; (ii) takes pleasure in doing so; (iii) is competent at the activity characteristic of empathy; and, (iv) has good judgment as to when it is epistemically appropriate to engage in empathy. After establishing that empathy meets (...) all the necessary conditions to be classified as an intellectual virtue, we proceed to discuss Battaly’s argument according to which empathy is a skill rather than a virtue. We contend, contra Battaly, that the agent who possesses the virtue of empathy: (a) sometimes foregoes opportunities to engage in the activity characteristic of empathy because it is the virtuous thing to do, (b) does not make deliberate errors, and (c) her actions are always ultimately aiming at epistemic goods.

Mental representations remain the central posits of psychology after many decades of scrutiny. However, there is no consensus about the representational format(s) of biological cognition. This paper provides a survey of evidence from computational cognitive psychology, perceptual psychology, developmental psychology, comparative psychology, and social psychology, and concludes that one type of format that routinely crops up is the language-of-thought (LoT). We outline six core properties of LoTs: (i) discrete constituents; (ii) role-filler independence; (iii) predicate–argument structure; (iv) logical operators; (v) inferential (...) promiscuity; and (vi) abstract content. These properties cluster together throughout cognitive science. Bayesian computational modeling, compositional features of object perception, complex infant and animal reasoning, and automatic, intuitive cognition in adults all implicate LoT-like structures. Instead of regarding LoT as a relic of the previous century, researchers in cognitive science and philosophy-of-mind must take seriously the explanatory breadth of LoT-based architectures. We grant that the mind may harbor many formats and architectures, including iconic and associative structures as well as deep-neural-network-like architectures. However, as computational/representational approaches to the mind continue to advance, classical compositional symbolic structures – that is, LoTs – only prove more flexible and well-supported over time.

Back to the Rough Ground is a philosophical investigation of practical knowledge, with major import for professional practice and the ethical life in modern society. Its purpose is to clarify the kind of knowledge that informs good practice in a range of disciplines such as education, psychotherapy, medicine, management, and law. Through reflection on key modern thinkers who have revived cardinal insights of Aristotle, and a sustained engagement with the Philosopher himself, it presents a radical challenge to the scientistic assumptions (...) that have dominated how these professional domains have been conceived, practiced, and institutionalized.

In this collection of recent essays (several appearing in English for the first time), John Dunn brings his characteristically acute and penetrative insight to a wide range of political issues. In the first essay, 'The history of political theory', Professor Dunn argues for the importance of a historical perspective in the study of political thought. Other pieces engage with central concepts of political philosophy such as obligation, trust, freedom of conscience and property. A group of studies tackle specific contemporary problems (...) and future dangers, for example racism and the dilemma of humanitarian intervention. The volume as a whole articulates the many dangers, but also the huge importance of, contemporary politics, and provides a representative collection of work by one of the most astute political commentators writing today.

Reliabilism—the view that a belief is justified iff it is produced by a reliable process—is often characterized as a form of consequentialism. Recently, critics of reliabilism have suggested that since it is a form of consequentialism, reliabilism condones a variety of problematic trade-offs involving cases where someone forms an epistemically deficient belief now that will lead her to more epistemic value later. In the present paper, we argue that the relevant argument against reliabilism fails because it equivocates. While there is (...) a sense in which reliabilism is a kind of consequentialism, it is not of a kind on which we should expect problematic trade-offs. (shrink)

Epistemic Consequentialism Consequentialism is the view that, in some sense, rightness is to be understood in terms conducive to goodness. Much of the philosophical discussion concerning consequentialism has focused on moral rightness or obligation or normativity. But there is plausibly also epistemic rightness, epistemic obligation, and epistemic normativity. Epistemic rightness is often denoted with talk … Continue reading Consequentialism Epistemic →.

Perceptual systems respond to proximal stimuli by forming mental representations of distal stimuli. A central goal for the philosophy of perception is to characterize the representations delivered by perceptual systems. It may be that all perceptual representations are in some way proprietarily perceptual and differ from the representational format of thought (Dretske 1981; Carey 2009; Burge 2010; Block ms.). Or it may instead be that perception and cognition always trade in the same code (Prinz 2002; Pylyshyn 2003). This paper rejects (...) both approaches in favor of perceptual pluralism, the thesis that perception delivers a multiplicity of representational formats, some proprietary and some shared with cognition. The argument for perceptual pluralism marshals a wide array of empirical evidence in favor of iconic (i.e., image-like, analog) representations in perception as well as discursive (i.e., language-like, digital) perceptual object representations.

Powerful conversations between His Holiness the Dalai Lama and leading scientists on the most pressing issue of our time. Engage with leading scientists, academics, ethicists, and activists, as well as His Holiness the Dalai Lama and His Holiness the Karmapa, who gathered in Dharamsala, India, for the twenty-third Mind and Life conference to discuss arguably the most urgent questions facing humanity today: What is happening to our planet? What can we do about it? How do we balance the concerns of (...) people against the rights of animals and against the needs of an ecosystem? What is the most skillful way to enact change? And how do we fight on, even when our efforts seem to bear no fruit? Inspiring, edifying, and transformative, this should be required reading for any citizen of the world. (shrink)

Dispositionalism about belief has had a recent resurgence. In this paper we critically evaluate a popular dispositionalist program pursued by Eric Schwitzgebel. Then we present an alternative: a psychofunctional, representational theory of belief. This theory of belief has two main pillars: that beliefs are relations to structured mental representations, and that the relations are determined by the generalizations under which beliefs are acquired, stored, and changed. We end by describing some of the generalizations regarding belief acquisition, storage, and change.

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.

Most theories of concepts take concepts to be structured bodies of information used in categorization and inference. This paper argues for a version of atomism, on which concepts are unstructured symbols. However, traditional Fodorian atomism is falsified by polysemy and fails to provide an account of how concepts figure in cognition. This paper argues that concepts are generative pointers, that is, unstructured symbols that point to memory locations where cognitively useful bodies of information are stored and can be deployed to (...) resolve polysemy. The notion of generative pointers allows for unresolved ambiguity in thought and provides a basis for conceptual engineering. (shrink)

My aim in this paper is to provide an account of practical judgement, for Kant, that situates it within his theory of judgement as a whole—particularly, with regards to the distinction between the determining and reflecting use of judgement. I argue that practical judgement is a kind of determining judgement, but also one in which reflecting judgement plays a significant role. More specifically, I claim that practical judgement arises from the cooperation of the reflecting power of judgement with the faculty (...) of reason—the former assisting the latter in the application of its principle. I conclude by considering a possible role for feeling in practical judgement. (shrink)

One effect of information technology is the increasing need to present information visually. The trend raises intriguing questions. What is the logical status of reasoning that employs visualization? What are the cognitive advantages and pitfalls of this reasoning? What kinds of tools can be developed to aid in the use of visual representation? This newest volume on the Studies in Logic and Computation series addresses the logical aspects of the visualization of information. The authors of these specially commissioned papers explore (...) the properties of diagrams, charts, and maps, and their use in problem solving and teaching basic reasoning skills. As computers make visual representations more commonplace, it is important for professionals, researchers and students in computer science, philosophy, and logic to develop an understanding of these tools; this book can clarify the relationship between visuals and information.

The question of whether perception is encapsulated from cognition has been a major topic in the study of perception in the past decade. One locus of debate concerns the role of attention. Some theorists argue that attention is a vehicle for widespread violations of encapsulation; others argue that certain forms of cognitively driven attention are compatible with encapsulation, especially if attention only modulates inputs. This paper argues for an extreme thesis: no effect of attention, whether on the inputs to perception (...) or on perceptual processing itself, constitutes a violation of the encapsulation of perception.

Short‐term memory in vision is typically thought to divide into at least two memory stores: a short, fragile, high‐capacity store known as iconic memory, and a longer, durable, capacity‐limited store known as visual working memory (VWM). This paper argues that iconic memory stores icons, i.e., image‐like perceptual representations. The iconicity of iconic memory has significant consequences for understanding consciousness, nonconceptual content, and the perception–cognition border. Steven Gross and Jonathan Flombaum have recently challenged the division between iconic memory and VWM by (...) arguing against the idea of capacity limits in favor of a flexible resource‐based model of short‐term memory. I argue that, while VWM capacity is probably governed by flexible resources rather than a sharp limit, the two memory stores should still be distinguished by their representational formats. Iconic memory stores icons, while VWM stores discursive (i.e., language‐like) representations. I conclude by arguing that this format‐based distinction between memory stores entails that prominent views about consciousness and the perception–cognition border will likely have to be revised.

Perceptual representations pick out individuals and attribute properties to them. This paper considers the role of perceptual attribution in determining or guiding perceptual reference to objects. We consider three extant models of the relation between perceptual attribution and perceptual reference–all attribution guides reference, no attribution guides reference, or a privileged subset of attributions guides reference–and argue that empirical evidence undermines all three. We then defend a flexible-attributives model, on which the range of perceptual attributives used to guide reference shifts adaptively (...) with context. This model underscores the remarkable and dynamic intelligence of our perceptual capacities. We elucidate implications of the model for the boundary between perception and propositional thought.

According to one important proposal, the difference between perception and cognition consists in the representational formats used in the two systems (Carey, 2009; Burge, 2010; Block, 2014). In particular, it is claimed that perceptual representations are iconic, or image-like, while cognitive representations are discursive, or language-like. Taking object perception as a test case, this paper argues on empirical grounds that it requires discursive label-like representations. These representations segment the perceptual field, continuously pick out objects despite changes in their features, and (...) abstractly represent high-level features, none of which appears possible for purely iconic representations.

Arnon Avron has written: “Dunn-McCall logic RM is by far the best understood and the most well-behaved in the family of logics developed by the school of Anderson and Belnap.” I agree. There is the famous saying: “Do not let the perfect become the enemy of the good.” I might say: “good enough.” In this spirit, I will examine the logic R-Mingle, exploring how it is only a “semi-relevant logic” but still a paraconsistent logic. I shall discuss the history of (...) RM, and compare RM to Anderson and Belnap’s system R of relevant implication and to classical two-valued logic. There is a “consumer’s guide,” evaluating these logics as “tools,” in the light of my recent work on “Humans as Rational Toolmaking Animals.”. (shrink)

According to a classic but nowadays discarded philosophical theory, perceptual experience is a complex of nonconceptual sensory states and full-blown propositional beliefs. This classical dual-component theory of experience is often taken to be obsolete. In particular, there seem to be cases in which perceptual experience and belief conflict: cases of known illusions, wherein subjects have beliefs contrary to the contents of their experiences. Modern dual-component theories reject the belief requirement and instead hold that perceptual experience is a complex of nonconceptual (...) sensory states and some other sort of conceptual state. The most popular modern dual-component theory appeals to sui generis propositional attitudes called ‘perceptual seemings’. This article argues that the classical dual-component theory has the resources to explain known illusions without giving up the claim that the conceptual components of experience are beliefs. The classical dual-component view, though often viewed as outdated and implausible, should be regarded as a serious contender in contemporary debates about the nature of perceptual experience.

It is an orthodoxy in cognitive science that perception can occur unconsciously. Recently, Hakwan Lau, Megan Peters and Ian Phillips have argued that this orthodoxy may be mistaken. They argue that many purported cases of unconscious perception fail to rule out low degrees of conscious awareness while others fail to establish genuine perception. This paper presents a case of unconscious perception that avoids these problems. It also advances a general principle of ‘phenomenal coherence’ that can insulate some forms of evidence (...) for unconscious perception from the methodological critiques of Lau, Peters and Phillips.

"Bartley and Radnitzky have done the philosophy of knowledge a tremendous service. Scholars now have a superb and up-to-date presentation of the fundamental ideas of evolutionary epistemology." --Philosophical Books.

This commentary critically examines the view of the relationship between perception and memory in Ned Block's *The Border Between Seeing and Thinking*. It argues that visual working memory often stores the outputs of perception without altering their formats, allowing online visual perception to access these memory representations in computations that unfold over longer timescales and across eye movements. Since Block concedes that visual working memory representations are not iconic, we should not think of perceptual representations as exclusively iconic either.

The target article attempted to draw connections between broad swaths of evidence by noticing a common thread: Abstract, symbolic, compositional codes, that is, language-of-thoughts (LoTs). Commentators raised concerns about the evidence and offered fascinating extensions to areas we overlooked.

The author makes the case that Plato is engaged not only in thinking but also, and more important, in doing¿that what we do with the knowledge is crucial, because it can determine the meaning and purpose of our own life. She saw that he was not merely engaging in rational philosophical discussion, but that the dialogues of Plato, especially up to the Republic, embody the Socratic exhortation for each individual to "take care for the soul." The dialogues therefore embody both (...) a rational philosophy and a system of spiritual/religious principles and doctrines whose purpose is to lay out¿in a public forum¿the path a true disciple needs to take to have a personal and direct experience of spiritual illumination, or enlightenment.
