Can Essence Provide Knowledge of Metaphysical Necessity? A Reply to Jago

Philosophia - In this paper I argue against Mark Jago’s recent suggestion that ordinary knowers can move from knowledge of essence to knowledge of metaphysical necessity.     

Are Metaphysical Claims Testable?

Philosophia - To consider metaphysical claims a priori and devoid of empirical content, is a rather commonplace received opinion. This paper attempts an exploration of a contemporary philosophical...     

Does Conceivability Entail Metaphysical Possibility?

In this paper, we argue that ‘Weak Modal Rationalism’, which is the view that ideal primary positive conceivability entails primary metaphysical possibility, is self‐defeating. To this end, we outline two reductio arguments against ‘Weak Modal Rationalism’. The first reductio shows that, from supposing that ‘Weak Modal Rationalism’ is true, it follows that conceivability both is and is not conclusive evidence for possibility. The second reductio shows that, from supposing that ‘Weak Modal Rationalism’ is true, it follows that it is possible that ‘Weak Modal Rationalism’ is necessarily false, and hence that ‘Weak Modal Rationalism’ is false. We then argue that adopting a weaker position according to which conceivability is merely prima facie evidence for possibility provides limited protection from our criticism of conceivability arguments. 1     

Metaphysical underdetermination: why worry?

Various forms of underdetermination that might threaten the realist stance are examined. That which holds between different ‘formulations’ of a theory (such as the Hamiltonian and Lagrangian formulations of classical mechanics) is considered in some detail, as is the ‘metaphysical’ underdetermination invoked to support ‘ontic structural realism’. The problematic roles of heuristic fruitfulness and surplus structure in attempts to break these forms of underdetermination are discussed and an approach emphasizing the relevant structural commonalities is defended.     

Justice: Metaphysical,After All?

Political liberals, following Rawls, believe that justice should be ‘political’ rather than ‘metaphysical.’ In other words, a conception of justice ought to be freestanding from first-order moral and metaethical views. The reason for this is to ensure that the state’s coercion be justified to citizens in terms that meet political liberalism’s principle of legitimacy. I suggest that privileging a political conception of justice involves costs—such as forgoing the opportunity for political theory to learn from other areas of philosophy. I argue that it is not clear that it provides any benefit in return. Whether a political conception of justice more adequately satisfies the liberal principle of legitimacy than a metaphysical conception of justice is an open question. To show this, I describe three ways in which political conceptions of justice have been developed within the literature. I then argue that while each might be helpful in finding reasons that reasonable citizens can accept, all face challenges in satisfying the liberal principle of legitimacy. Political conceptions of justice confront the same set of justificatory problems as ‘metaphysical’ conceptions. The question of whether a political conception is preferable should receive greater scrutiny.     

Does the Modality Effect Exist? and if So, Which Modality Effect?

The modality effect is a central issue in multimedia learning [see Mayer (Cambridge University Press, 2005a), for a review]. Sweller’s Cognitive Load Theory (CLT), for example, presumes that an illustrated text is better understood when presented visually rather than orally. The predictive power of CLT lies in how it links in to Baddeley’s (1986) model of working memory and Penney’s (Mem Cognit 17:398–442, 1989) Separate-Streams Hypothesis. Ginns’s (Learn Instr 4:313–331, 2005) recent meta-analysis also supports the modality effect (d = 0.72, based on 43 independent effects). This article replicates the meta-analysis of the modality effect based on 86 independent effects (with within-study subgroups as the unit of analysis and with mean of the outcomes as the dependent measure), with results showing a reduction of the overall effect size by almost half (d = 0.38), and even more when Duval and Tweedie’s Trim and Fill method is used to correct publication bias (d = 0.20). This article also widens the scope of the analysis of moderator variables (e.g. Pace of presentation, Type of visualization, Research group) as well as their potentially confounded effects. Finally, it is argued that, for theoretical reasons, the so-called modality effect cannot be based on Penney’s or Baddeley’s theories and must be explained in a different way.     

Reading paradigms: From lab to cyberspace?

Computer-controlled display procedures useful for doing reading research are discussed. The procedures used in the present research vary the text unit size (from single words to half-sentences), the amount of context available (no context and varying amounts of prior text), text movement (centered words or successive left-to-right placement), and use of text highlighting (present, absent). The data suggest links between the display attributes and the subjects’ coding strategies during reading of mathematical word problems. Display attributes can influence the time course of processing, the subjectively coded unit size, and the nature of linguistic processing. The data also have implications for display attributes that may make reading in cyberspace more user friendly for both novice and expert readers.     

Lifelong Education: From Conflict to Consensus?

The concept of lifelong education received wide criticism and rejection in many educational circles in the 1970s. Recent developments in educational research and the increasing influence of postmodernist thought, the paper argues, are major factors in the return to favour of lifelong education. While a postmodern society is one characterised more by conflict than by consensus, the paper suggests that consensus on the importance of lifelong education might be one precondition for such a society.     

Understanding phenomena: From social to collective?

In making sense of the world, we typically cooperate, join forces, and draw on one another's competence and expertise. A group or community in which there is a well-functioning division of cognitive-epistemic labor can achieve levels of understanding that a single agent who relies exclusively on her own capacities would probably never achieve. However, is understanding also collective? I.e., is understanding something that can be possessed by a group or community rather than by individuals? In this paper, I develop an account of understanding phenomena according to which understanding a phenomenon requires reasonably endorsing an adequate and intelligible epistemic mediator that accounts for this phenomenon. I then show that understanding, conceived along these lines, can be attributed to collective entities. An important result of my arguments will be that a collective entity's understanding cannot (always) be reduced to the sum of the understandings of the individuals belonging to it. This is because a collective entity can sometimes be rightfully claimed to understand a phenomenon while none of its individual members understands it.     

From Nature to Culture? Diogenes and Philosophical Anthropology

This essay is concerned with the central issue of philosophical anthropology: the relation between nature and culture. Although Rousseau was the first thinker to introduce this topic within the modern discourse of philosophy and the cultural sciences, it has its origin in Diogenes the Cynic, who was a disciple of Socrates. In my essay I (1) historically introduce a few aspects of philosophical anthropology, (2) deal with the nature–culture exchange, as introduced in Kant, then I (3) relate this topic to the Ancient Cynic Diogenes. Surprisingly, although we usually identify Critical Theory and Freudian psychoanalysis as theories that have shown that cultural progress should not be comprehended as a development from nature to culture, and that instead it should be conceived as a development from culture against (external as well as internal) nature, I show that Cynicism can be conceived as a vivid example within the history of our culture that reveals a double sense of repression and alienation, which is part of human civilization and mankind.     

Advances Toward Evidence-Based Practice: Where to From Here?

Evidence-based practice has a long history; however, attempts to bridge the gap between science and practice have been only partially effective and much work remains to be done. Part of the problem has been the unilateral approach associated with dissemination of research findings to clinical practitioners. In this special series, Goldfried and colleagues (2014--this issue) suggest a two-way bridge, in which practitioners are afforded the opportunity to disseminate their rich clinical experiences to researchers as well. In this manner, a more collaborative working relationship is espoused. Surveys of practitioners on the use of CBT procedures in the treatment of panic disorder, social anxiety disorder, and generalized anxiety disorder are described. The findings are reviewed and limitations associated with the surveys are noted. Finally, future directions are suggested for rapprochement, hopefully resulting in a greater synthesis of research and practice.     

From Desire to Civility: Is Xunzi a Hobbesian?

This article argues that, contrary to conventional wisdom, Xunzi’s and Hobbes’s understandings of human nature are qualitatively different, which is responsible for the difference in their respective normative political theory of a civil polity. This article has two main theses: first, where Hobbes’s deepest concern was with human beings’ unsocial passions, Xunzi was most concerned with human beings’ appetitive desires (yu 欲), material self-interest, and resulting social strife; second, as a result, where Hobbes strove to transform the pathological (anti-)politics of resentment into the politics of recognition by creating rational egalitarian citizenship under the all-encompassing constitutional sovereign power, Xunzi attempted to nourish human beings’ basic appetitive desires (yu 欲) by instituting a li 禮 ordered civil entity. This article concludes by showing how Confucian civility that Xunzi reconstructed by means of the li 禮 can effectively deal with unsocial passions.     

Rosy with Sider? The Case of the Metaphysical Liar

An important trend in contemporary metaphysics denies that the structure of natural language is an important datum for investigating fundamental structure. Ted Sider proceeds on this basis to propose a metaphysical semantics for natural language. Within this framework he argues that natural language and a fundamental, ‘jointcarving’, language could be subject to distinct logics. Developing an argument of Hartry Field’s, I show that Sider’s preferred option of fundamental classicality combined with non-fundamental non-classicality trivialises within the framework of Siderian metaphysical semantics. The position can be saved only by revising key claims about truth and metaphysical semantics. This has serious implications for methdology in the metaphysics of logic.
