Symbols in computer programs are not necessarily isomorphic in form or capability to neural processes. Representations in our models are stored descriptions of the world and human behavior, created by a human interpreter; representations in the brain are neither immutable forms nor encoded in some language. Although the term " symbol " can be usefully applied to describe words, smoke signals, neural maps, and graphic icons, a science of symbol processing requires distinguishing between the structural, developmental, and interactive nature of (...) different forms of representing.

In the 1970s, we conceived of a rule explanation as supplying the causal and social context that justifies a rule, an objective documentation for why a rule is correct. Today we would call such descriptions post-hoc design rationales, not proving the rules? correctness, but providing a means for later interpreting why the rule was written and facilitating later improvements.

Knowledge engineers once viewed themselves as priests; they received "The Word" from experts above, added nothing to the content, but codified it accurately into written rules, and passed it down to ordinary folks as commandments to live by.

The MER created a virtual experience of being on Mars. This book examines how the MER has changed the nature of planetary field science.

van der Velde's &de Kamps's neural blackboard architecture is similar to “activation trace diagrams” (Clancey 1999), which represent how categories are temporally related as neural activations in parallel-hierarchical compositions. Examination of other comprehension examples suggests that a given syntactic categorization (structure assembly) can be incorporated in different ways within an open composition by different kinds of anchoring relations (delay assemblies). Anchors are categorizations, too, so they cannot be reused until their containing construction is completed (bindings are resolved).

Information processing theories of memory and skills can be reformulated in terms of how categories are physically and temporally related, a process called conceptual coordination. Dreaming can then be understood as a story-understanding process in which two mechanisms found in everyday comprehension are missing: conceiving sequences (chunking categories in time as a higher-order categorization) and coordinating across modalities (e.g., relating the sound of a word and the image of its meaning). On this basis, we can readily identify isomorphisms between dream (...) phenomenology and neurophysiology, and explain the function of dreaming as facilitating future coordination of sequential, cross-modal categorization (i.e., REM sleep lowers activation thresholds, “unlearning”).

“Conceptual coordination” analysis bridges connectionism and symbolic approaches by positing a “process memory” by which categories are physically coordinated in time. Focusing on dysfunctions and odd behaviors, like slips, reveals the function of consciousness, especially constructive processes that are often taken for granted, which are different from conventional programming constructs. Newell strongly endorsed identifying architectural limits; the heuristic of “diagnose unusual behaviors” will provide targets of opportunity that greatly strengthen the Newell Test.

Supervaluationism is often described as the most popular semantic treatment of indeterminacy. There’s little consensus, however, about how to fill out the bare-bones idea to include a characterization of logical consequence. The paper explores one methodology for choosing between the logics: pick a logic thatnorms beliefas classical consequence is standardly thought to do. The main focus of the paper considers a variant of standard supervaluational, on which we can characterizedegrees of determinacy. It applies the methodology above to focus ondegree logic. (...) This is developed first in a basic, single-premise case; and then extended to the multipremise case, and to allowdegreesof consequence. The metatheoretic properties of degree logic are set out. On the positive side, the logic is supraclassical—all classical valid sequents are degree logic valid. Strikingly, metarules such as cut and conjunction introduction fail. (shrink)

In this article I argue (against the views of Russell Dancy and Gregory Vlastos, but in support of the views of R. E. Allen, Gail Fine, and Francesco Fronterotta) that Euthyphro 5c-d and 6d-e show that Socrates had a metaphysics, early version of the theory of forms. I disagree with Fronterotta only on the separation of the forms in the Euthyphro.

Socrates is one the most important thinkers in western philosophy, yet he remains enigmatic, having left behind no works of his own. Instead, his thought is understood primarily through the work of his followers. In this accessible introduction, William Prior assesses Socrates the man, his famous trial, and the nature of his philosophy.

The idea of role‐playing makes some people nervous – even some people who play role‐playing games (RPGs). So the idea of immersion is central to understanding how Dungeons Dragons and other aspects of participatory culture work. Phenomenology is a kind of “philosophy of mind” associated with the works of twentieth‐century philosophers Edmund Husserl, Martin Heidegger, Jean‐Paul Sartre, and Maurice Merleau‐Ponty, among others. The domain of phenomenology encompasses the entire range of experiences in the world, paying attention to what Husserl called (...) “intentionality,” or how our consciousness is directed toward particular objects in the world. The fact that this is presented as an atypical approach to play, or at least one that requires some effort, invites us to ask about typical modes of play if visualization of in‐game events is not that mode. This chapter concluded by scratch the surface of a complete phenomenological description of role‐playing. (shrink)

This essay examines the role of non-existent objects in "epistemological ontology"--the study of the entities that make thinking possible. An earlier revision of Meinong's Theory of Objects is reviewed, Meinong's notions of Quasisein and Aussersein are discussed, and a theory of Meinongian objects as "combinatorially possible" entities is presented.

Can one coherently integrate Darwin's view of evolution with an affirmation of the value of existence? In this fresh, lean, and substantive volume, William Meyer addresses this important question. By carefully analyzing Darwin's own writings and by drawing on the philosophical perspectives of William James, Alfred North Whitehead, and others, Meyer persuasively redirects the cultural conversation about Darwin away from the retrospective question of origins toward the prospective question concerning the ultimate significance of evolutionary life. As James recognized, (...) the question about the reality of God is more critical for the forward-looking question of value than it is for the backward-looking question of origins. Darwin was a theist in search of a better theism, and because theology had not yet caught up to him, he became increasingly agnostic and caught between his mechanistic understanding of nature, on the one hand, and his affirmation of the value and beauty of the world, on the other. Whitehead's philosophy of organism offers a way to integrate Darwin's evolutionary insights with his affirmation of the grandeur of nature. Meyer's clearly written and richly argued book enables us to integrate our evolutionary understanding of the world with our experience of value within it. (shrink)

Disney's computer‐animated musical film, Moana tells the tale of Moana, the daughter of Tui, the chief of a Polynesian island, Motunui. Bound by the legendary tradition of her ancestors, Moana is expected to follow her lineage and take over as chief when she grows up. As the authors dig beneath the surface level of the story, they find a metaphorical and philosophical level to Moana's journey. The story of Moana has layers. First, it is literally a tale of Moana's voyage (...) outside beyond the reef so that she can restore the heart of Te Fiti and save the people of Motunui. She closes this tale with a happy ending as she simultaneously lives the life that she freely chooses, becomes the leader of her people (by saving them) as her parents wanted, and honors her tradition insofar as she restores her ancestors' tradition of wayfinding.

This article compares topographical and archaeological remains of the Thermopylae frontier with the ancient testimonia of the sixth century historian Procopius of Caesareia (De aedificiis4.2.1.–22). It was revealed that: many of the frontier fortifications described were initially built before the sixth century; the fortified κλεισούρα mentioned should be equated with the Dhéma Pass; and the commercial settlement of Myropóles is best identified with the modern village of Káto Dhió Vouná. Written in Attic prose, this passage represents a rhetorical exercise, the (...) climax of which turned not on the ancient battlefield of Thermopylae, but rather on a mountain pass and it's highway that neutralized the Thermopylae defenses if they were ever controlled by the enemy. We were told that only the Emperor Justinian's wisdom could grasp this critical fact. Additionally, Procopius employed many rhetorical devices in this narrative: τóπος, χρóνος,, ἄγαλμα, ἔκφρασις, πανηγρικóς and employed imperial propaganda, praise, and exaggeration as well. In short, the passage is a classic example of selective story telling that may have found its inspiration in the Hunnic raid of 539/540 and the Herodotean account of the Persian invasion of 480 BC. While Procopius' account remains our best topographical description of the late antique Thermopylae frontier, one can only say that more archaeological questions were left unanswered than were resolved. In short, as an archaeological source, theDe aedificiisis a disappointing and vexing resource filled with equivocations. Finally, one may doubt that Procopius ever did visit the Thermopylae frontier, even though during his career he certainly had ample opportunity to do so. His account, therefore, must have been based upon secondary sources, whether imperial archival material, itineraries, or military staff reports and were not the result of personal autopsy. (shrink)

Aquinas' theology can be understood only if one comes to grips with his metaphysics of being. The relevance of this perspective is exhibited in his treatment of topics like creation, goodness, happiness, truth, freedom of the will, the unity of the human being, prayer and providence, God's personhood, divine love, God and violence, God's unknowablility, the Incarnation, the Trinity, God's existence, theological language and even laughter. This book endeavors to treat these questions in a clear and convincing language. Is there (...) a better method for improving one's own theology than by grappling with the arguments of Thomas Aquinas? (shrink)

We review the role of reference within Davidson's T‐theoretic account of language and examine his contention that reference is inscrutable. More generally, we look at the explanatory role of reference in the context of Davidson's philosophy: whether there are explanations that directly appeal to reference, and whether there are explanations that appeal to beliefs about reference.

As identity and authenticity discourses increasingly saturate everyday life, so too have these concepts spread across the humanities and social sciences literatures. Many scholars may be interested in identity and authenticity, but lack knowledge of paradigmatic or disciplinary approaches to these concepts. This volume offers readers insight into social constructionist approaches to identity and authenticity. It focuses on the processes of identification and authentication, rather than on subjective experiences of selfhood. There are no attempts to settle what authentic identities are. (...) On the contrary, contributors demonstrate that neither identities nor their authenticity have a single or fixed meaning. Chapters provide exemplars of contemporary research on identity and authenticity, with significant diversity among them in terms of the identities, cultural milieu, geographic settings, disciplinary traditions, and methodological approaches considered. Contributors introduce readers to a number of established and emerging identity groups from sites around the world, from yogis and punks to fire dancers and social media influencers. Their conceptual work stretches from the micro-analytic to the ethno-national as authors employ a variety of qualitative methods including ethnographic fieldwork, interviewing, and the collection and analysis of naturally-occurring interactions. Several of the chapters look directly at identification and authentication, while others focus on the social and cultural backdrops that structure these practices-what unites them is the adoption of social constructionist sensibilities. This book will appeal to anyone interested in understanding identity and authenticity. (shrink)

Trotz eines verbreiteten Zweifels gegenüber Wahrheitsansprüchen wird in vielen persönlichen und sozialen Lebensbereichen Wahrheit selbstverständlich vorausgesetzt. Ohne Wahrheit kann keine Gesellschaft bestehen. Gewissen, Entscheidungsfreiheit, Menschenrechte, der Glaube an Gott, selbst der Zweifel, die Verständigung über Lebensziele und die Erfahrung von Glück sind ohne Wahrheit nicht möglich. Das Buch ergründet und entfaltet die Einsicht, dass der Mensch das Wahrheitswesen ist. Die Erkenntnis, wie sie sich bei Thomas von Aquin findet, dass Wahrheit auf der höchsten Ebene ihrer Abstraktion gedacht werden muss, dient (...) dabei bis heute als Verständnisschlüssel auch für unseren zeitgenössischen Begriff von Wahrheit.
