Self-regulated learning is critical for learning across tasks, domains, and contexts. Despite its importance, research shows that not all learners are equally skilled at accurately and dynamically monitoring and regulating their self-regulatory processes. Therefore, learning technologies, such as intelligent tutoring systems, have been designed to measure and foster SRL. This paper presents an overview of over 10 years of research on SRL with MetaTutor, a hypermedia-based ITS designed to scaffold college students’ SRL while they learn about the human circulatory system. (...) MetaTutor’s architecture and instructional features are designed based on models of SRL, empirical evidence on human and computerized tutoring principles of multimedia learning, Artificial Intelligence in educational systems for metacognition and SRL, and research on SRL from our team and that of other researchers. We present MetaTutor followed by a synthesis of key research findings on the effectiveness of various versions of the system on learning outcomes. First, we focus on findings from self-reports, learning outcomes, and multimodal data and their contributions to our understanding of SRL with an ITS. Second, we elaborate on the role of embedded pedagogical agents as external regulators designed to scaffold learners’ cognitive and metacognitive SRL strategy use. Third, we highlight and elaborate on the contributions of multimodal data in measuring and understanding the role of cognitive, affective, metacognitive, and motivational processes. Additionally, we unpack some of the challenges these data pose for designing real-time instructional interventions that scaffold SRL. Fourth, we present existing theoretical, methodological, and analytical challenges and briefly discuss lessons learned and open challenges. (shrink)

Nevertheless, any competent speaker will know what it means. What explains our ability to understand sentences we have never before encountered? One natural hypothesis is that those novel sentences are built up out of familiar parts, put together in familiar ways. This hypothesis requires the backing hypothesis that English has a compositional semantic theory.

Scholars looking back to the earliest stirrings of the philosophical tradition in ancient Greece have often seen a rational approach to nature cleaving itself off from an older approach, that of the mythographer. If this account were right, we would have here a major (and perhaps the ?rst major) drawing of an epistemic boundary. There are, however, mounting reasons to question this narrative that have been accumulating across several modern disciplines. This paper explores the most important challenges to the myth-to-science (...) narrative and suggests that the different ways of framing the ancient debates have much to do with the boundaries between modern disciplines and/or academic cultures.

Montague and Kaplan began a revolution in semantics, which promised to explain how a univocal expression could make distinct truth-conditional contributions in its various occurrences. The idea was to treat context as a parameter at which a sentence is semantically evaluated. But the revolution has stalled. One salient problem comes from recurring demonstratives: "He is tall and he is not tall". For the sentence to be true at a context, each occurrence of the demonstrative must make a different truth-conditional contribution. (...) But this difference cannot be accounted for by standard parameter sensitivity. Semanticists, consoled by the thought that this ambiguity would ultimately be needed anyhow to explain anaphora, have been too content to posit massive ambiguities in demonstrative pronouns. This article aims to revived the parameter revolution by showing how to treat demonstrative pronouns as univocal while providing an account of anaphora that doesn't end up re-introducing the ambiguity.

§§3-4 of the Begriffsschrift present Frege’s objections to a dominant if murky nineteenth-century semantic picture. I sketch a minimalist variant of the pre-Fregean picture which escapes Frege’s criticisms by positing a thin notion of semantic content which then interacts with a multiplicity of kinds of truth to account for phenomena such as modality. After exploring several ways in which we can understand the existence of multiple truth properties, I discuss the roles of pointwise and setwise truth properties in modal logic. (...) I argue that thinking of supertruth and determinate truth as setwise truth properties allows an understanding of supervaluationist approaches to vagueness which escapes both Williamson’s objections to and a needless metalinguistic orientation of traditional supervaluationism.

Cappelen and Dever present a forceful challenge to the standard view that perspective, and in particular the perspective of the first person, is a philosophically deep aspect of the world. Their goal is not to show that we need to explain indexical and other perspectival phenomena in different ways, but to show that the entire topic is an illusion.

Bad Language is the first textbook on an emerging area in the study of language: non-idealized language use, the linguistic behaviour of people who exploit language for malign purposes. This lively, accessible introduction offers theoretical frameworks for thinking about such topics as lies and bullshit, slurs and insults, coercion and silencing.

There’s an interesting debate in moral and political philosophy about the nature of, and relationship between, ideal and non-ideal theory. In this paper we discuss whether an analogous distinction can be drawn in philosophy of language. Our conclusion is negative: Even if you think that distinction can be put to work within moral and political philosophy, there’s no useful way to extend it to work that has been done in the philosophy of language.

Supervaluational accounts of vagueness have come under assault from Timothy Williamson for failing to provide either a sufficiently classical logic or a disquotational notion of truth, and from Crispin Wright and others for incorporating a notion of higher-order vagueness, via the determinacy operator, which leads to contradiction when combined with intuitively appealing ‘gap principles’. We argue that these criticisms of supervaluation theory depend on giving supertruth an unnecessarily central role in that theory as the sole notion of truth, rather than (...) as one mode of truth. Allowing for the co-existence of supertruth and local truth, we define a notion of local entailment in supervaluation theory, and show that the resulting logic is fully classical and allows for the truth of the gap principles. Finally, we argue that both supertruth and local truth are disquotational, when disquotational principles are properly understood. (shrink)

Can humans and artificial intelligences share concepts and communicate? Making AI Intelligible shows that philosophical work on the metaphysics of meaning can help answer these questions. Herman Cappelen and Josh Dever use the externalist tradition in philosophy to create models of how AIs and humans can understand each other. In doing so, they illustrate ways in which that philosophical tradition can be improved. The questions addressed in the book are not only theoretically interesting, but the answers have pressing practical (...) implications. Many important decisions about human life are now influenced by AI. In giving that power to AI, we presuppose that AIs can track features of the world that we care about (for example, creditworthiness, recidivism, cancer, and combatants). If AIs can share our concepts, that will go some way towards justifying this reliance on AI. This ground-breaking study offers insight into how to take some first steps towards achieving Interpretable AI. (shrink)

What did the Romans know about their world? Quite a lot, as Daryn Lehoux makes clear in this fascinating and much-needed contribution to the history and philosophy of ancient science. Lehoux contends that even though many of the Romans’ views about the natural world have no place in modern science—the umbrella-footed monsters and dog-headed people that roamed the earth and the stars that foretold human destinies—their claims turn out not to be so radically different from our own. Lehoux draws (...) upon a wide range of sources from what is unquestionably the most prolific period of ancient science, from the first century BC to the second century AD. He begins with Cicero’s theologico-philosophical trilogy _On the Nature of the Gods_, _On Divination_, and _On Fate_, illustrating how Cicero’s engagement with nature is closely related to his concerns in politics, religion, and law. Lehoux then guides readers through highly technical works by Galen and Ptolemy, as well as the more philosophically oriented physics and cosmologies of Lucretius, Plutarch, and Seneca, all the while exploring the complex interrelationships between the objects of scientific inquiry and the norms, processes, and structures of that inquiry. This includes not only the tools and methods the Romans used to investigate nature, but also the Romans’ cultural, intellectual, political, and religious perspectives. Lehoux concludes by sketching a methodology that uses the historical material he has carefully explained to directly engage the philosophical questions of incommensurability, realism, and relativism. By situating Roman arguments about the natural world in their larger philosophical, political, and rhetorical contexts, _What Did the Romans Know?_ demonstrates that the Romans had sophisticated and novel approaches to nature, approaches that were empirically rigorous, philosophically rich, and epistemologically complex.

The semantic puzzles posed by propositional attitude contexts have, since Frege, been understood primarily in terms of certain substitution puzzles. We will take as paradigmatic of such substitution puzzles cases in which two coreferential proper names cannot be intersubstituted salva veritate in the context of an attitude verb. Thus, for example, the following sentences differ in truth value: (1) Lois Lane believes Superman can fly. (2) Lois Lane believes Clark Kent can fly. despite the fact that "Superman" and "Clark Kent" (...) pick out the same individual.1 Equivalently, the following sentence may be true: (3) Lois Lane believes that Superman can fly, but that Clark Kent cannot fly. despite the coreferentiality of the names. (It will at times be convenient to appeal to this conjunctive attitude report in order to fix a single context of utterance.) Substitution failures such as these create a puzzle when conjoined with the assumptions (a) that attitude reports report a binary relation between an individual and some object of that individual's attitude and (b) that that object of the attitude is determined by the content of the complement sentence in the attitude report. If all of the terms in two complement sentences (e.g., "Superman can fly" and "Clark Kent can fly") have the same semantic content, then, prima facie, they ought to generate the same object of believe and, a fortiori, materially equivalent attitude reports. Frege, famously, attempts to defuse the puzzle by positing a semantic value of sense in addition to that of reference, and thereby distinguishing the semantic contents of the two complement sentences.

Manley and Wasserman (2008) join the chorus of opposition to the possibility of conditional analysis of dispositions. But that score cannot be settled without more careful attention to the implicit philosophical methodology. Some of the opposition to such an analysis badly overestimates the effect of counterexamples, as if the Gettier example were sufficient to refute the possibility of conjunctive analysis of knowledge. A general objection to a form of analysis must satisfy a number of constraints, and Manley and Wasserman join (...) the chorus too in failing to satisfy them. Most significant is the optional presupposition that the conditional used in analysis will exhibit some sort of centring. We show that even a careful effort to repair and reform Manley and Wasserman's objection to provide a satisfactory argument requires, ultimately, appeal to centring. Worse, the particular positive proposal they offer is vulnerable to a minor variant of their own counterexample. (shrink)

It is a fundamental feature of language that words refer to things. Much attention has been devoted to the nature of reference, both in philosophy and in linguistics. Puzzles of Reference is the first book to give a comprehensive accessible survey of the fascinating work on this topic from the 1970s to the present day. -/- Written by two eminent philosophers of language, Puzzles of Reference offers an up-to-date introduction to reference in philosophy and linguistics, summarizing ideas such as Kripke's (...) revolutionary theory and presenting the various challenges in a clear and accessible manner. As the text does not assume prior training in philosophy or linguistics, it is ideal for use as part of a philosophy of language course for philosophy students or for linguistics students. -/- Puzzles of Reference belongs to the series Contemporary Introductions to Philosophy of Language, in which each book provides an introduction to an important area of the philosophy of language, suitable for students at any level.

To say that this lump of sugar is soluble is to say that it would dissolve, if submerged anywhere, at any time and in any parcel of water. To say that this sleeper knows French, is to say that if, for example, he is ever addressed in French, or shown any French newspaper, he responds pertinently in French, acts appropriately or translates correctly into his own tongue.

• The Static Conception of Semantics (Preliminary Version): A semantic theory should assign a proposition, conceived of as some carrier of meaning that can play the role of truth condition determination, to each (or at least each declarative) sentence.

In her very interesting ‘First-personal modes of presentation and the problem of empathy’, L. A. Paul argues that the phenomenon of empathy gives us reason to care about the first person point of view: that as theorists we can only understand, and as humans only evince, empathy by appealing to that point of view. We are skeptics about the importance of the first person point of view, although not about empathy. The goal of this paper is to see if we (...) can account for empathy without the ideology of the first person. We conclude that we can. (shrink)

In her Transient Truths, Berit Brogaard defends temporalism about proposition content from the more traditional eternalist views. I argue that both temporalism and eternalism are equally capable of accommodating all the data, and thus suggest that we should adopt a neutralism that holds there is no serious or resolvable dispute. Contra Brogaard, I argue that neither disagreement patterns nor belief dynamics favor temporalism over eternalism. I also suggest that Brogaard's defense of operator over quantificational semantics for tense is unnecessary, because (...) quantificational tense semantics can be given a temporalist reading, and operator tense semantics can be given an eternalist reading.

The relationship between conceptions of law and conceptions of nature is a complex one, and proceeds on what appear to be two distinct fronts. On the one hand, we frequently talk of nature as being lawlike or as obeying laws. On the other hand there are schools of philosophy that seek to justify ethics generally, or legal theory specifically, in conceptions of nature. Questions about the historical origins and development of claims that nature is lawlike are generally treated as entirely (...) distinct from the development of ethical natural law theories. By looking at the many intersections of law and nature in antiquity, this paper shows that such a sharp distinction is overly simplistic, and often relies crucially on the imposition of an artificial and anachronistic suppression of the role of gods or divinity in the worlds of ancient natural philosophy. Furthermore, by tightening up the terms of the debate, we see that the common claim that a conception of ‘laws of nature’ only emerges in the Scientific Revolution is built on a superficial reading of the ancient evidence.Keywords: Ancient science; Philosophy of science; Philosophy of law; Ancient theology; Scientific Revolution.

Since Kaplan’s "Demonstratives", it has become a common-place to distinguish between the character and content of an expression, where the content of an expression is what it contributes to "what is said" by sentences containing that expression, and the character gives a rule for determining, in a context, the content of an expression. A tacit assumption of theories of character has been that character is autonomous from content – that semantic evaluation starts with character, adds context, and then derives content. (...) One consequence of this autonomy thesis is that the rules for character can contain no variables bound by content-level operators elsewhere in the sentence. Tacit appeal to this consequence features essentially both in Jason Stanley’s recent argument that all contextual ambiguity must be linked to "elements in the actual syntactic structure of the sentence uttered" in his "Context and Logical Form" and in my arguments against character-based theories of complex demonstratives in my "Complex Demonstratives". However, I argue here that the autonomy thesis is unmotivated, and show that we can separate Kaplan’s notion of character into two independent components: an aspect of meaning which is context-sensitive, and an aspect of meaning that is exempted from scopal interactions with other operators. The resulting semantic framework allows constructions similar to Kaplan’s rejected notion of "monsters begat by elegance", but which are both more empirically adequate and more theoretically versatile. Having made the distinction between context-sensitivity and autonomy from scopal interaction, I show how it allows binding into the character of expressions and hence undermines the immediate success of both Stanley’s argument and my former argument against character-based theories of complex demonstratives, and discuss briefly the prospects for reinstating modified versions of those arguments. Finally, I show how that same distinction allows a defusing of Kripke’s modal argument against a descriptive theory of names. Once autonomy from semantic interaction is separated from context-sensitivity, the first of those two alone can be used to capture the modal rigidity of proper names.. (shrink)

Concluding his discussion of bee reproduction in Book 3 ofGeneration of Animals, Aristotle makes a famous methodological pronouncement about the relationship between sense perception and theory in natural history. In the very next sentence, he casually remarks that the unique method of reproduction that he finds in bees should not be surprising, since bees have something ‘divine’ about them. Although the methodological pronouncement gets a fair bit of scholarly attention, and although Aristotle's theological commitments in cosmology and metaphysics are well (...) known, scholars have almost universally passed over the comment about bees and divinity in silence. This paper aims to show why that comment is no mere throwaway, and offers an exploration and elaboration of the ways in which divinity operates even at fairly mundane levels in his natural philosophy, as an important Aristotelian explanation for order, proportion and rationality, even in the lowest of animals.

. Once constituted, scientific facts have a way of roaming about on their own in the world, much divorced from the circumstances of their original constitution. An important part of Latour and Woolgar's discussion in Laboratory Life was to draw attention to how facts are used once they are at the final stage of their constitution. What I propose to do here is to go one step further, and to follow a single fact around in the wild—to tag it, as (...) it were, much as a biologist might tag an animal with a radio collar—and then look to see where it turns up. The fact I have chosen is especially taggable, simply because it happens to be fantastic: I refer to the fact that magnets will lose their power of attraction if they are rubbed with garlic. This fact is also useful because it shows up in authors spanning fifteen centuries, from Plutarch through Rabelais and beyond, and over this time it shows some interesting behaviors. Of course, in the end, the garlic-magnet antipathy was disproved, and so changed its epistemological status, moving from one extreme to the other: from the obviously true to the obviously ridiculous.

Context and Communication offers an introduction to a central theme in the study of language: the various ways in which what we say depends on the context of speech and thought.

It is written to be accessible to someone with no prior knowledge of the material or, indeed, any prior knowledge (...) of philosophy, and is ideal for use as part of a philosophy of language course by students of philosophy or linguistics.

In our book The Inessential Indexical we argue that the various theses of essential indexicality all fail. Indexicals are not essential, we conclude. One essentiality thesis we target in the third chapter is the claim that indexical attitudes are essential for action. Our strategy is to give examples of what we call impersonal action rationalizations , which explain actions without citing indexical attitudes. To defeat the claim that indexical attitudes are essential for action, it suffices that there could be even (...) one successful impersonal action rationalization. In what follows we bolster our case against an essential connection between action and the de se (or indexicality), first by developing a range of new action models and secondly by responding to challenges from Dilip Ninan, Stephan Torre, and José Luis Bermúdez .

A total theory of linguistic understanding is often taken to require three subtheories: a syntactic theory, a semantic theory, and a pragmatic theory. The semantic theory occupies an intermediary role – it takes as input structures generated by the syntax, assigns to those structures meanings, and then passes those meanings on to the pragmatics, which characterizes the conversational 1 impact of those meanings. Semantic theories thus seek to explain phenomena such as truth conditions of and inferential relations among sentences/utterances, anaphoric (...) relations among terms, and ambiguity and incoherence of expressions.

Linguistic intervention in rational decision making is standardly captured in terms of information change. But the standard view gives us no way to model interventions involving expressions that only have an attentional effects on conversational contexts. How are expressions with non‐informational content – like epistemic modals – used to intervene in rational decision making? We show how to model rational decision change without information change: replace a standard conception of value (on which the value of a set of worlds reduces (...) to values of individual worlds in the set) with one on which the value of a set of worlds is determined by a selection function that picks out a generic member world. We discuss some upshots of this view for theorizing in philosophy and formal semantics. (shrink)

A “slingshot” proof suggested by Kurt Gödel (1944) has been recast by Stephen Neale (1995) as a deductive argument showing that no non-truthfunctional sentence connective can permit the combined use, within its scope, of two truth-functionally valid inference principles involving defi- nite descriptions. According to Neale, this result provides indirect support for Russell’s Theory of Descriptions and has broader philosophical repercussions because descriptions occur in non-truth-functional constructions used to motivate talk about (e.g.) necessity, time, probability, causation, obligation, facts, states of (...) affairs, and propositions.

What is the relationship between observations, predictions, texts, and instruments in ancient astrology? By distinguishing between two distinct kinds of observation claim in astrological texts, I show on the one hand the rhetorical and theoretical importance of each kind of observation claim to ancient astrological traditions, and on the other hand how practices of ancient astrology break from observation once astronomical phenomena become reliably predictable. We thus see a shift in practice from observationally derived predictions to a reliance on textual (...) and instrumental authority, even though the rhetoric of ancient astrology still tries to maintain an emphasis on observation.Author Keywords: Astrology; Astrometeorology; Astronomy; Divination; Instruments; Observation; Parapegmata; Prediction; Rhetoric; Signs; Weather.

Modal fictionalists propose to defuse the unwanted ontological commitments of modal realism by treating modal realism as a fictional story, and modal assertions as assertions, prefixed by a fictionalist operator, that something is true in that story. However, consideration of conditionals with modal antecedents raises the problem ofembedding, which shows that the simple prefixing strategy cannotsucceed. A compositional version of the fictionalist strategy isdeveloped and critiqued, and some general semantic morals aredrawn from the failures of both strategies.

Sententialism: An adequate semantic theory for a language assigns semantic values to complex expressions (typically on the basis of the semantic values of the syntactic parts of those complex expressions), with the assignment process culminating in the assignment of appropriate semantic values (typically propositions or truth conditions) to entire sentences. Sententialism is so-called because it takes the task of semantic theory proper to be exhausted once semantic values have been assigned to full sentences. Beyond the sentence may lay further linguistic (...) phenomena broadly construed, such as various discourse properties and relations, but any such phenomena are relegated to the pragmatics. Sententialism thus typically goes hand-in-hand with a larger philosophical perspective according.. (shrink)
