Reliabilism has come under recent attack for its alleged inability to account for the value we typically ascribe to knowledge. It is charged that a reliably-produced true belief has no more value than does the true belief alone. I reply to these charges on behalf of reliabilism; not because I think reliabilism is the correct theory of knowledge, but rather because being reliably-produced does add value of a sort to true beliefs. The added value stems from the fact that a (...) reliably-held belief is non-accidental in a particular way. While it is widely acknowledged that accidentally true beliefs cannot count as knowledge, it is rarely questioned why this should be so. An answer to this question emerges from the discussion of the value of reliability; an answer that holds interesting implications for the value and nature of knowledge. (shrink)

It is generally assumed that there are (at least) two fundamental epistemic goals: believing truths, and avoiding the acceptance of falsehoods. As has been often noted, these goals are in conflict with one another. Moreover, the norms governing rational belief that we should derive from these two goals depend on how we weight them relative to one another. However, it is not obvious that there is one objectively correct weighting for everyone in all circumstances. Indeed, as I shall argue, it (...) looks as though there are circumstances in which a range of possible weightings of the two goals are all equally epistemically rational. (shrink)

It will startle no one to hear that there is widespread disagreement among philosophers about the nature and criteria of epistemic justification. There are many distinct notions of epistemic justification, distinguished from one another in a bewildering variety of ways. There are internalist justification, externalist justification, coherentist justification, foundationalist justification, deontic justification, consequentialist justification, propositional justification, doxastic justification, personal justification, situational justification, objective justification, subjective justification, cognitive justification, and structural justification. None of these is quite equivalent to another, yet each (...) is proposed as a way in which something can be epistemically justified. (shrink)

Current epistemological dogma has it that the twin goalsof believing truths and avoiding errors exhaust our cognitive aspirations.On such a view, (call it the TG view) the only evaluationsthat count as genuinely epistemological are those that evaluatesomething (a belief, believer, set of beliefs, a cognitivetrait or process, etc.) in terms of its connection to thesetwo goods. In particular, this view implies that all theepistemic value of knowledge must be derived from thevalue of the two goals cited in TG. I argue (...) thatthis implication is false, and thus that the TG view must be abandoned. I propose a candidate to replacethe TG view that makes better sense of the value ofknowledge. (shrink)

There are good reasons for pursuing a theory of knowledge by way of understanding the connection between knowledge and luck. Not surprisingly, then, there has been a burgeoning of interest in “luck theories” of knowledge as well as in theories of luck in general. Unfortunately, “luck” proves to be as recalcitrant an analysandum as “knows.” While it is well worth pursuing a general theory of luck despite these difficulties, our theory of knowledge might be made more manageable if we could (...) find a more restricted notion that captured the core phenomena of luck that are relevant to whether or not someone knows. This essay makes the attempt to delineate such a notion, called “mere coincidence.”. (shrink)

Coherence theorists have universally defined justification as a relation only among (the contents of) belief states, in contradistinction to other theories, such as some versions of founda­tionalism, which define justification as a relation on belief states and appearance states.

Jonathan Kvanvig's book, The Value of Knowledge and the Pursuit of Understanding (Kvanvig, 2003), is a wonderful example of doing epistemology in a style that Kvanvig himself has termed "value−driven epistemology." On this approach, one takes questions about epistemic value to be central to theoretical concerns, including the concern to provide an adequate account of knowledge. This approach yields the demand that theories of knowledge must provide, not just an adequate account of the nature of knowledge, but also an account (...) of the value of knowledge. Given the near−universal assumption that knowledge has a special kind of value, this demand seems reasonable, though surprisingly hard to satisfy. Another consequence of this approach to doing epistemology is that certain assumptions about epistemic value, like what sorts of things have it and what sorts of things don't, and where such value comes from, become much more salient to the epistemic enterprise. In his book, Kvanvig challenges the assumption that knowledge has some unique store of epistemic value. And he investigates the matter by asking questions about what the bearers of epistemic value are and where they get it. He concludes, of course, that knowledge as we have come to conceive it in 21st century epistemology has no such special value. (shrink)

This is the story of North Carolina parent choice advocates' push for the creation and expansion of choice policies in the state. The exploration of the politics, ideology, and interests surrounding parent choice in this conversation includes but also stretches beyond the most frequently discussed choice policies of charter schools, school vouchers, and tuition tax credits. Here, Lewis makes the argument that parents push for these policies are closely akin to parents' rejection of busing and redistricting policies in Charlotte-Mecklenburg and (...) Raleigh-Durham, parents' advocating for the state-support of home-schooling options across the state, and parents' pushing for the expansion of magnet and intradistrict choice options. He shows how central to parents' advocacy for all of these policies lies a more foundational desire to reconceputalize public schooling, with parents having much more individual control over how public funding is used for the education of their children.

This paper outlines an original interactivist-constructivist approach to modelling intelligence and learning as a dynamical embodied form of adaptiveness and explores some applications of I-C to understanding the way cognitive learning is realized in the brain. Two key ideas for conceptualizing intelligence within this framework are developed. These are: intelligence is centrally concerned with the capacity for coherent, context-sensitive, self-directed management of interaction; and the primary model for cognitive learning is anticipative skill construction. Self-directedness is a capacity for integrative process (...) modulation which allows a system to "steer" itself through its world by anticipatively matching its own viability requirements to interaction with its environment. Because the adaptive interaction processes required of intelligent systems are too complex for effective action to be prespecified learning is an important component of intelligence. A model of self-directed anticipative learning is formulated based on interactive skill construction, and argued to constitute a central constructivist process involved in cognitive development. SDAL illuminates the capacity of intelligent learners to start with the vague, poorly defined problems typically posed in realistic learning situations and progressively refine them, transforming them into problems with sufficient structure to guide the construction of a solution. Finally, some of the implications of I-C for modelling of the neuronal basis of intelligence and learning are explored; in particular, Quartz and Sejnowski's recent neural constructivism paradigm, enriched by Montague and Sejnowski's dopaminergic model of anticipative-predictive neural learning, is assessed as a promising, but incomplete, contribution to this approach. The paper concludes with a fourfold reflection on the divergence in cognitive modelling philosophy between the I-C and the traditional computational information processing approaches. (shrink)

Tasks, tools, and techniques that we perform, use, and acquire, define the elements of expertise which we value as the hallmarks of goal-driven behavior. Somehow, the creation of tools enables us to define new tasks, or is it that the envisioning of new tasks drives us to invent new tools? Or maybe it is that new tools engender new techniques which then result in new tasks? This jumble of issues will be explored and discussed in this diverse collection of papers. (...) Individually, few of the papers are related to each other by topic or by techniques of analysis. Collectively, all focus on tasks performed using tools and discuss the techniques of tool use which enable differences in performance and expertise across individuals, societies, and (even) species. -/- .

Constraints and dependencies among the elements of embodied cognition form patterns or microstrategies of interactive behavior. Hard constraints determine which microstrategies are possible. Soft constraints determine which of the possible microstrategies are most likely to be selected. When selection is non‐deliberate or automatic the least effort microstrategy is chosen. In calculating the effort required to execute a microstrategy each of the three types of operations, memory retrieval, perception, and action, are given equal weight; that is, perceptual‐motor activity does not have (...) a privileged status with respect to memory. Soft constraints can work contrary to the designer's intentions by making the access of perfect knowledge in‐the‐world more effortful than the access of imperfect knowledge in‐the‐head. These implications of soft constraints are tested in two experiments. In experiment 1 we varied the perceptual‐motor effort of accessing knowledge in‐the‐world as well as the effort of retrieving items from memory. In experiment 2 we replicated one of the experiment 1 conditions to collect eye movement data. The results suggest that milliseconds matter. Soft constraints lead to a reliance on knowledge in‐the‐head even when the absolute difference in perceptual‐motor versus memory retrieval effort is small, and even when relying on memory leads to a higher error rate and lower performance. We discuss the implications of soft constraints for routine interactive behavior, accounts of embodied cognition, and tool and interface design. (shrink)

The framework of plateaus, dips, and leaps shines light on periods when individuals may be inventing new methods of skilled performance. We begin with a review of the role performance plateaus have played in experimental psychology, human–computer interaction, and cognitive science. We then reanalyze two classic studies of individual performance to show plateaus and dips which resulted in performance leaps. For a third study, we show how the statistical methods of Changepoint Analysis plus a few simple heuristics may direct our (...) focus to periods of performance change for individuals. For the researcher, dips become the marker of exploration where performance suffers as new methods are invented and tested. Leaps mark the implementation of a successful new method and an incremental jump above the path plotted by smooth and steady log–log performance increments. The methods developed during these dips and leaps are the key to surpassing one's teachers and acquiring extreme expertise. (shrink)

Acquiring expertise in a task is often thought of as an automatic process that follows inevitably with practice according to the log‐log law (aka: power law) of learning. However, as Ericsson, Chase, and Faloon (1980) showed, this is not true for digit‐span experts and, as we show, it is certainly not true for Tetris players at any level of expertise. Although some people may simply “twitch” faster than others, the limit to Tetris expertise is not raw keypress time but the (...) techniques acquired by players that allow them to use the tools provided by the hardware and software to compensate for the game's relentlessly increasing drop speed. Unfortunately, these increases in drop speed between Tetris levels make performance plateaus very short and quickly followed by game death. Hence, a player's success at discovering, exploring, and practicing new techniques for the tasks of board preparation, board maintenance, optimal placement discovery, zoid rotation, lateral movement of zoids, and other tasks important to expertise in Tetris is limited. In this paper, we analyze data collected from 492 Tetris players to reveal the challenges they confronted while constructing expertise via the discovery of new techniques for gameplay at increasingly difficult levels of Tetris.

Designed to introduce music students and musicians to the vitality of music philosophical discourse, Philosophical Perspectives on Music explores diverse accounts of the nature and value of music. It offers an accessible, even-handed consideration of philosophical orientations without advocating any single one, demonstrating that there are a number of ways in which music may reasonably be understood. This unique approach examines the strengths and advantages of each perspective as well as its inevitable shortcomings. From the pre-Socratic Greeks to idealism, through (...) phenomenology, and on to contemporary socio-cultural critiques, this wide-ranging survey examines the views of selected influential thinkers in sufficient detail to permit their voices to be personally and meaningfully experienced. Striving to portray philosophy as an intriguing dialogue rather than a dogmatic source of definitive answers, it invites readers to become full participants in an ongoing process of philosophical debate with vital contemporary relevance and extensive practical significance. Examining what music is, how it works, and what music is good for, this book encourages musicians to join in important conversations that shape both the ways they practice their art and the ways in which they and others understand it. Accessible to students with little or no background in music philosophy, Philosophical Perspectives on Music provides the foundation for applied or professional philosophies while also introducing readers to the richness of the philosophical quest. Ideal for philosophy of music and philosophy of music education courses, it is also enlightening reading for students of musicology, music theory, and music performance. Featuring interdisciplinary dialogue, this insightful text addresses issues common to the concerns of all musicians. (shrink)

Donald Campbell has long advocated a naturalist epistemology based on a general selection theory, with the scope of knowledge restricted to vicarious adaptive processes. But being a vicariant is problematic because it involves an unexplained epistemic relation. We argue that this relation is to be explicated organizationally in terms of the regulation of behavior and internal state by the vicariant, but that Campbell's selectionist approach can give no satisfactory account of it because it is opaque to organization. We show how (...) organizational constraints and capacities are crucial to understanding both evolution and cognition and conclude with a proposal for an enriched, generalized model of evolutionary epistemology that places high-order regulatory organization at the center.

In this paper we outline a theory of normative functionality aimed at understanding the nature of adaptive systems as globally structured, integrated systems. More specifically, the account is concerned with understanding the process relations constitutive of such systems. The explanatory agenda of this approach includes the following questions.

Why games? How could anyone consider action games an experimental paradigm for Cognitive Science? In 1973, as one of three strategies he proposed for advancing Cognitive Science, Allen Newell exhorted us to “accept a single complex task and do all of it.” More specifically, he told us that rather than taking an “experimental psychology as usual approach,” we should “focus on a series of experimental and theoretical studies around a single complex task” so as to demonstrate that our theories of (...) human cognition were powerful enough to explain “a genuine slab of human behavior” with the studies fitting into a detailed theoretical picture. Action games represent the type of experimental paradigm that Newell was advocating and the current state of programming expertise and laboratory equipment, along with the emergence of Big Data and naturally occurring datasets, provide the technologies and data needed to realize his vision. Action games enable us to escape from our field's regrettable focus on novice performance to develop theories that account for the full range of expertise through a twin focus on expertise sampling and longitudinal studies of simple and complex tasks.

Understanding the nature of errors in a simple, rule‐based task—programming a VCR—required analyzing the interactions among human cognition, the artifact, and the task. This analysis was guided by least‐effort principles and yielded a control structure that combined a rule hierarchy task‐to‐device with display‐based difference‐reduction. A model based on this analysis was used to trace action protocols collected from participants as they programmed a simulated VCR. Trials that ended without success (the show was not correctly programmed) were interrogated to yield insights (...) regarding problems in acquiring the control structure. For successful trials (the show was correctly programmed), steps that the model would make were categorized as matches to the model; steps that the model would not make were violations of the model. The model was able to trace the vast majority of correct keystrokes and yielded a business‐as‐usual account of the detection and correction of errors. Violations of the model fell into one of two fundamental categories. The model provided insights into certain subcategories of errors; whereas, regularities within other subcategories of error suggested limitations to the model. Although errors were rare when compared to the total number of correct actions, they were important. Errors were made on 4% of the keypresses that, if not detected, would have prevented two‐thirds of the shows from being successfully recorded. A misprogrammed show is a minor annoyance to the user. However, devices with the approximate complexity of a VCR are ubiquitous and have found their way into emergency rooms, airplane cockpits, power plants, and so on. Errors of ignorance may be reduced by training; however, errors in the routine performance of skilled users can only be reduced by design. (shrink)

The general structure of Steels & Belpaeme's (S&B's) central premise is appealing. Theoretical stances that focus on one type of mechanism miss the fact that multiple mechanisms acting in concert can provide convergent constraints for a more robust capacity than any individual mechanism might achieve acting in isolation. However, highlighting the significance of complex constraint interactions raises the possibility that some of the relevant constraints may have been left out of S&B's own models. Although abstract modeling can help clarify issues, (...) it also runs the risk of oversimplification and misframing. A more subtle implication of the significance of interacting constraints is that it calls for a close relationship between theoretical and empirical research. (shrink)
