Differential academic language proficiency is an issue of major educational concern, bearing on problems varying from pupil performance, to social prospects, and citizenship. In this paper we develop a conception of the language-acquiring subject, and we discuss the consequences for understanding differential language proficiency in schools. Starting from Wittgenstein's meaning-as-use theory we show that learning a language requires an activity that relates the subject both to the community of language users, and to the things language is about. In opposition to (...) Luntley, we contend that this does not mean that linguistic development involves linguistic adjustment to the world 'as it is'. It is argued that, in as far as linguistic development involves a process of adjustment, this concerns conceptions about the world as it is presupposed to be—a 'world' that is subjected to doubt and revision time and again. With respect to dealing with differential academic language proficiency, this approach to linguistic development suggests bringing pupils into situations which require active participation in processes of 'negotiating meaning', including negotiating the prevailing presuppositions about what the world is like. This also puts novices in a different position—less assimilatory—recognising their co-constructive potencies at a more fundamental level. (shrink)

Many philosophers of education emphasise the impossibility to really ‘solve’ philosophical—and with that, educational—problems these days. Philosophers have been trying to give philosophy a new, constructive turn in the face of this insolvability. This paper focuses on irony-based approaches that try to exploit the very uncertainty of philosophical issues to further philosophical understanding. We will first briefly discuss a few highlights of historical uses of irony as a philosophical tool. Then we concentrate on two different interpretations of irony, formulated by (...) Bransen and Rorty, that aim at gaining insight into how we make meaning of the world, while at the same time recognising that such an understanding would be impossible. After discussing some problematic aspects of these interpretations a third interpretation of irony is developed, based on a third view of the nature of meaning-making. Following these three interpretations, we will discuss their philosophical merits and the different kinds of insight they can produce for philosophy of education. (shrink)

In this paper I address the current debate on ontic versus epistemic conceptualizations of mechanistic explanation in the mechanisms literature. Illari recently argued that good explanations are subject to both ontic and epistemic constraints: they must describe mechanisms in the world in such fashion that they provide understanding of their workings. Elaborating upon Illari’s ‘integration’ account, I argue that causal role function discovery of mechanisms and their components is an epistemic prerequisite for achieving these two aims. This analysis extends Illari’s (...) account in important ways, putting more pressure on ontic readings of mechanistic explanation and providing an answer to the question how ontic and epistemic constraints on mechanistic explanation are related. I argue these point in terms of cases on memory research drawn from neuroscience and research on extinct neurogenetic mechanisms from early nervous systems biology. (shrink)

This paper investigates conceptions of explanation, teleology, and analogy in the works of Immanuel Kant (1724-1804) and Georges Cuvier (1769-1832). Richards (2000, 2002) and Zammito (2006, 2012, 2018) have argued that Kant’s philosophy provided an obstacle for the project of establishing biology as a proper science around 1800. By contrast, Russell (1916), Outram (1986), and Huneman (2006, 2008) have argued, similar to suggestions from Lenoir (1989), that Kant’s philosophy influenced the influential naturalist Georges Cuvier. In this article, I wish to (...) expand on and further the work of Russell, Outram, and Huneman by adopting a novel perspective on Cuvier and considering (a) the similar conceptions of proper science and explanation of Kant and Cuvier, and (b) the similar conceptions of the role of teleology and analogy in the works of Kant and Cuvier. The similarities between Kant and Cuvier show, contrary to the interpretation of Richards and Zammito, that some of Kant’s philosophical ideas, whether they derived from him or not, were fruitfully applied by some life scientists who wished to transform life sciences into proper sciences around 1800. However, I also show that Cuvier, in contrast to Kant, had a workable strategy for transforming the life sciences into proper sciences, and that he departed from Kant’s philosophy of science in crucial respects.

The Russian invasion of Ukraine on February 24, 2022, has already caused large amounts of greenhouse gas (GHG) emissions and will continue to do so for manyyears after hostilities have ceased mainly because of the emissions linked to the rebuilding of destroyed or damaged housing, public buildings, infrastructure, factories, and the like. My aim in this paper is to discuss how in a time of climate emergency such emissions of war should impact the political morality of states initiating, continuing, and (...) ending war (through a just and enduring peace) as understood by just war theory (JWT). My point of departure is a study by Lennard de Klerk and six co-authors detailing the emissions of the first year of the Russo-Ukrainian war. (shrink)

Dynamic Epistemic Logic This article tells the story of the rise of dynamic epistemic logic, which began with epistemic logic, the logic of knowledge, in the 1960s. Then, in the late 1980s, came dynamic epistemic logic, the logic of change of knowledge. Much of it was motivated by puzzles and paradoxes. The number … Continue reading Dynamic Epistemic Logic →.

Decentralized clinical trials (DCTs) have the potential to advance the conduct of clinical trials, but raise several ethical issues, including obtaining valid informed consent. The debate on the ethical issues resulting from digitalization is predominantly focused on direct risks relating to for example data protection, safety, and data quality. We submit however, that a broader view on ethical aspects of DCTs is needed to touch upon the new challenges that come with the DCT practice. Digitalization has impacts that go beyond (...) its direct purposes, by shaping behaviors, experiences, social relations, and values. We examine four elements of the informed consent procedure that are affected by DCTs, while taking these soft impacts of technologies into account: (i) informing participants and testing understanding, (ii) freedoms in relation to responsibilities and burdens, (iii) trust in participant-researcher relations, and (iv) impacts on the concept of privacy. Our analysis reveals that a broad view is key for optimal conduct of DCTs. In addition, it provides insight into the ethical impacts of DCTs on informed consent. Technologies such as DCTs potentially have profound impacts which are not immediately addressed by the existing regulatory frameworks, but nonetheless important to recognize. These findings can guide future practices of DCTs to foster the important values of clinical research in this novel approach for conducting clinical trials. (shrink)

Jill de Villiers has argued that children's mastery of sentential complements plays a crucial role in enabling them to succeed at false-belief tasks. Josef Perner has disputed that and has argued that mastery of false-belief tasks requires an understanding of the multiplicity of perspectives. This paper attempts to resolve the debate by explicating attributions of desires and beliefs as extensions of the linguistic practices of making commands and assertions, respectively. In terms of these linguistic practices one can explain why desire-talk (...) will precede belief-talk and why even older children will have difficulty attributing incompatible desires. (shrink)

According to the traditional view in the philosophy of logic facts of logic bear normative authority regarding how one ought to reason. Usually this is to mean that the relation of logical consequence between statements has some special relevance for how one’s beliefs should cohere. However, as I will argue in this article, this is just one way in which logic is normative for reasoning. For one thing, belief is not the only kind of mental state involved in reasoning. Besides (...) adopting and revising beliefs, rational agents pose and resolve questions. For another thing, the consequence relation of classical logic can be conservatively extended such that it includes logical relations between questions as well. Therefore, there is an argument to be made that not only the inference of new beliefs from extant beliefs but also the process of raising additional questions falls under the normative authority of logic. Accordingly, a nuanced account of the normativity of logic presents itself, which convincingly deals with problems such as clutter-avoidance and the paradox of the preface. (shrink)

To understand pre-Fregean theories of judgment and proposition, such as those found in Locke and the Port-Royal logic, it is important to distinguish between propositions in the modern sense and propositions in the pre-Fregean sense. By making this distinction it becomes clear that these pre-Fregean theories cannot be meant to solve the propositional attitude problem. Notwithstanding this fact, Locke and Arnauld are able to make a distinction between asserted and unasserted propositions (in their sense). The way Locke makes this distinction (...) turns out to be very different from the way it is made by Arnauld. (shrink)

In this essay I present what is, I contend, the free-will problem properly thought through, or at least presented in a form in which it is possible to think about it without being constantly led astray by bad terminology and confused ideas. Bad terminology and confused ideas are not uncommon in current discussions of the problem. The worst such pieces of terminology are "libertarian free will" and "compatibilist free will." The essay consists partly of a defense of the thesis that (...) the use of these phrases by writers on the problem of free will can only generate conceptual confusion and partly of a formulation of the problem that does not make use of them. I contend that this formulation is neutral with respect to the historically important positions on free will (e. g., compatibilism and incompatibilism). (shrink)

This monograph, the first of its kind in English, offers a detailed study of the Wenzi, a controversial Chinese philosophical text. The book also sheds light on text production and reception in Chinese history, with its changing views on authorship, originality, authenticity, and forgery.

The notion of cognitive act is of importance for an epistemology that is apt for constructive type theory, and for epistemology in general. Instead of taking knowledge attributions as the primary use of the verb 'to know' that needs to be given an account of, and understanding a first-person knowledge claim as a special case of knowledge attribution, the account of knowledge that is given here understands first-person knowledge claims as the primary use of the verb 'to know'. This means (...) that a cognitive act is an act that counts as cognitive from a first-person point of view. The method of linguistic phenomenology is used to explain or elucidate our epistemic notions. One of the advantages of the theory is that an answer can be given to some of the problems in modern epistemology, such as the Gettier problem. (shrink)

Gödel once offered an argument for the general reflection principle in set theory that took the form of an analogy with Leibniz' Monadology. I discuss the mathematical and philosophical background to Gödel's argument, reconstruct the proposed analogy in detail, and argue that it has no justificatory force.

In an earlier issue, I argue (2014) that psychology and epistemology should distinguish religious credence from factual belief. These are distinct cognitive attitudes. Levy (2017) rejects this distinction, arguing that both religious and factual “beliefs” are subject to “shifting” on the basis of fluency and “intuitiveness.” Levy’s theory, however, (1) is out of keeping with much research in cognitive science of religion and (2) misrepresents the notion of factual belief employed in my theory. So his claims don’t undermine my distinction. (...) I conclude by suggesting some approaches to empirically testing our views. (shrink)
