This paper deals with Dooyeweerd's radical thesis, i.e., his thesis that reason necessarily has a 'religious root' (radix = root). This thesis was Dooyeweerd's main justification for his own religious philosophy. First I argue that the arguments Dooyeweerd puts forward do not warrant his radical thesis. Secondly, I argue that Dooyeweerd's thesis itself is ambivalent between the theses (i) that religious commitments form the transcendental conditions for philosophical thinking and (ii) that religious commitments are constitutive for philosophy and (iii) that (...) religious commitments are regulative for philosophy. Each of these interpretations, I argue, is exposed to serious objections and leads to what Vincent Brummer has called 'the dilemma of a Christian philosophy'. I argue that Brummers solution for this dilemma is untenable. Since Dooyeweerd's radical thesis is untenable as it stands, so is his justification of his project of a 'Christian philosophy' ; and since Brummers solution to the dilemma is untenable as well, so is his justification of that project. In the last section of this paper I offer an alternative justification for such a project. The central concept therein is 'properly functioning noetic faculties'. (shrink)

Some statements are called reflexive. For example, the statement : „ This sentence consists of six words”. The reflexivity lies in the fact that the statement refers to itself. Reflexivity in the sense of self-reference can be used systematically as a philosophical method. Usually the use of this method (as I explain in section I) leads to some form or other of scepticism. But in addition, and this is the point of the article, this method can be used as a (...) means of finding certain grounds (foundations). This is argued in sections II-IV by means of an analysis of the „ transcendental pragmatics“ of Karl-Otto Apel. (shrink)

This paper argues, first, that biological evolution can be both random and divinely guided at the same time. Next it discusses the idea that the claim that evolution is unguided is not part of the science of evolution, and defends it against a number of objections.

In his recent book Waar geest is, is vrijheid [Where there is mind, there is freedom], Guus Labooy sets forth an original and intriguing argument, inspired by the work of John Duns Scotus, for substance dualism in the philosophy of mind. In this paper we argue that his argument, although worthy of serious attention, is under-supported. In section 2 we question the significance of the particular scotistic notion of freedom he uses in his argument, even though we agree with his (...) premise that humans do possess freedom in the libertarian sense. In section 3 we argue that Labooy fails to make his key contention that significant freedom requires an irreducible immaterial soul sufficiently plausible. The key problem is that he does not consider the work of physicalists who also believe in libertarian freedom. In addition, it is not self-evident that an immaterial soul, as opposed to a physical body, can possess significant freedom. This requires argument. In section 4 we comment on Labooy’s specific conception of dualism and advise him to change it into a conception in which the soul — and not the composition of soul and body — is the human person, for the latter conception has absurd consequences.

It has recently been argued that the following Rule should be part of any characterization of science: Claims concerning specific disputed facts should be endorsed only if they are sufficiently supported by the application of validated methods of research or discovery, and moreover that acceptance of this Rule should lead one to reject religious belief. This paper argues, first, that the Rule, as stated, should not be accepted as it suffers from a number of problems. And second, that even if (...) the Rule were to be acceptable, it should not lead one to reject religious belief. (shrink)

One of the goals of computerized tutoring systems is to optimize the learning of facts. Over a hundred years of declarative memory research have identified two robust effects that can improve such systems: the spacing and the testing effect. By making optimal use of both and adjusting the system to the individual learner using cognitive models based on declarative memory theories, such systems consistently outperform traditional methods (Van Rijn, Van Maanen, & Van Woudenberg, 2009). This adjustment process is driven (...) by a continuously updated estimate of the rate of forgetting for each item and learner on the basis of the learner's accuracy and response time. In this study, we investigated to what extent these estimates of individual rates of forgetting are stable over time and across different materials. We demonstrate that they are stable over time but not across materials. Even though most theories of human declarative memory assume a single underlying rate of forgetting, we show that, in practice, it makes sense to assume different materials are forgotten at different rates. If a computerized, adaptive fact‐learning system allowed different rates of forgetting for different materials, it could adapt to individual learners more readily. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Thomas Reid on MemoryRené van Woudenbergthis paper is a discussion of Thomas Reid’s views on memory as an “avenue of knowledge.” Part 1 deals with various remarks Reid makes concerning memory, knowledge, and belief which he holds to be “obvious and certain.” Part contains a more detailed discussion of Reid’s thesis that “memory is unaccountable.” Part 3 inquires how Reid’s critique of the Way of Ideas fits with his (...) own views on memory.Reid’s dealings with memory are part of his broader inquiries into the intellectual faculties of the human mind. In the Essays on the Intellectual Powers of Man Reid discusses not only memory, but other avenues of knowledge as well, such as perception and reasoning. In these essays Reid is doing straight epistemology. This is not to deny that Reid addresses other topics as well. In the essay on memory, for instance, Reid criticizes John Locke’s account of personal identity. But even then his discussion focusses on epistemological matters; one of his conclusions, for example, is that Locke confounded personal identity with the evidence we have of our personal identity, a thesis, Reid points out, that is bristled with absurd consequences. Although, then, Reid’s views on memory are related with his views on personal identity, I will abstain from a discussion of the latter. His epistemology of memory, I think, warrants attention in its own right.11. memory, knowledge, and beliefI.IIn Essay III of his Essays on the Intellectual Powers of Man [1784],2 entitled “Of Memory,” Reid writes: [End Page 117]It is by memory that we have an immediate knowledge of things past. The senses give us information of things only as they exist in the present moment.(EIP 339)Memory, says Reid, gives us knowledge of things past, whereas sense perception gives us knowledge of things present. Reid takes it to be “obvious and certain” (as the title of the first chapter of Essay III indicates) that “The object of memory, or thing remembered, must be something that is past; as the object of perception... must be something which is present. What now is, cannot be an object of memory; neither can that which is past and gone be an object of perception” (EIP 340).These remarks may, however, occasion some doubts. One way of explaining Reid’s remark that the object of memory is something that is past, is that whenever someone, S, remembers something, viz., that p, p will be a proposition about something that is past.3 This explanation gives the right result for such propositions as there was snowfall in late August, and she once visited Finland4 But, as Norman Malcolm has observed, it does not always give the right results.5 For, he says, there are cases of S remembering that p, where p is not a proposition about the past. Let p be his telephone number is 2 79-289-59 75, or his car is in the garage. What is remembered, in these cases, is a proposition about something that is not past, but present (or: about what is presently the case). It is, so it seems at least, possible for S to remember the present.It even seems possible for S “to remember the future” (something Aristotle deemed impossible).6 S can remember, for instance, that the game starts at 8:00 P.M., or that there will be elections next year.No doubt some will find these suggestions preposterous. Still, we say such things as “I remember my telephone number” and “I remember the game starts at 8:00 P.M.” Someone who balks at the suggestion that we can remember present and even future things, therefore, has to find a way of dealing with these quite common modes of saying. One way would be to argue that these manners of saying are incorrect, another that they are elliptical. Since the first thesis is unconvincing (it is, after all, correct, i.e., correct English to use the expressions under consideration), we are left with the second, viz., that these modes of saying are elliptical. Can this be made acceptable? Let us see.Might... (shrink)

Contrastivism is the claim that the knowledge relation is ternary, it relates three relata: a subject, a proposition, and a class of contrastive propositions. The present paper is a discussion of Jonathan Schaffer’s arguments in favour of contrastivism. The case is made that these are unconvincing: the traditional binary account of knowledge can handle the phenomena that ternarity is claimed to handle in a superior way.

Common-sense philosophy is important because it maintains that we can know many things about the world, about ourselves, about morality, and even about things of a metaphysical nature. The tenets of common-sense philosophy, while in some sense obvious and unsurprising, give rise to powerful arguments that can shed light on fundamental philosophical issues, including the perennial problem of scepticism and the emerging challenge of scientism. This Companion offers an exploration of common-sense philosophy in its many forms, tracing its development as (...) a concept and considering the roles it has been assigned to play throughout the history of philosophy. Containing fifteen newly commissioned chapters from leading experts in the history of philosophy, epistemology, the philosophy of science, moral philosophy and metaphysics, the volume will be an essential guide for students and scholars hoping to gain a greater understanding of the value and enduring appeal of common-sense philosophy.

Hoewel misschien minder dan vroeger, zijn velen van ons op zoek naar waarheid, of ‘de’ waarheid . We beseffen dat het ‘hebben’ van waarheid een groot goed is. We beseffen ook dat waarheid, of ‘de’ waarheid, soms of vaak, moeilijk te achterhalen is: het is een soms of vaak ongrijpbaar goed. Wie echter geen volslagen scepticus is kan in beginsel lijsten aanleggen van beweringen waarvan hij weet dat ze waar zijn, beweringen waarvan hij weet dat ze onwaar zijn, maar ook (...) van beweringen waarvan hij niet weet of ze waar dan wel onwaar zijn.

The idea that we can properly be held responsible for what we believe underlies large stretches of our social and institutional life; without that idea in place, social and institutional life would be unthinkable, and more importantly, it would stumble and fall. At the same time, philosophers have argued that this idea is strange, puzzling, beyond belief, false, meaningless or at any rate defective. The first section develops the alleged problem. The burden of this paper, however, is not to discuss (...) the merits of this idea but rather to measure the damage in case the idea turns out to be defective indeed. This is done by substantiating the claim that this idea indeed underlies large and important stretches of our social and institutional life. Section 2 substantiates that claim by presenting the results of a web search on the use of what I call "deontological epistemic expressions", i.e. expressions in which deontological and epistemological notions (both broadly construed) are combined; examples are "obligation to believe", "not permitted to forget", "right to know". The ubiquitous use of these expressions, I argue, is linguistic evidence for the claim that the contested idea indeed pervades our social life. Linguistic evidence, however, can be frail and misleading. From the fact that we say that the shade is moving we cannot conclude that shades really exist; likewise it may not be permitted to conclude from the ubiquitous use of deontological epistemic expressions that there really are doxastic obligations (and hence doxastic responsibilities). The third section, therefore, moves beyond the linguistic evidence and discusses two social institutions, viz. education and law as we find them in modern Western societies, and argues that they cannot be made sense of unless the contested idea is in place. Educational and legal systems of course vary greatly throughout the Western world. Such differences as exist, however, are irrelevant for the claim I will be making in this paper. The final section states the conclusion. (shrink)

Various tests have been proposed as helps to identify intrinsic properties. This paper compares three prominent tests and shows that they fail to pass adequate verdicts on a set of three properties. The paper examines whether improved versions of the tests can reduce or remove these negative outcomes. We reach the sceptical conclusion that whereas some of the tests must be discarded as inadequate because they don’t yield definite results, the remaining tests depend for their application on the details of (...) fundamental particle physics so much so that they cannot be relied upon.

The thesis developed and defended in this paper is that is it false that all knowledge is founded on experience. Much of our knowledge (or alleged knowledge), it is argued, is based on testimony. Still, many philosophers have either not dealt with testimony at all, or treated it very unkindly. One of the reasons for this is that those philosophers (such as Descartes and Locke) work with a concept of knowledge according to which knowledge is certain, indubitable, and/or self-evident. And (...) if knowledge is what these philosophers say it is, then there is no such thing as knowledge based on testimony indeed. Thomas Reid is introduced as holding that we do have testimonial knowledge and that therefore Descartes' and Locke's concept of knowledge is untenable. Reid furthermore holds that human beings are endowed with a disposition to accept or believe what otherstell us („the principle of credulity”). The working of this principle is refined through all kinds of experience. What Reid says or shows is how this disposition in fact operates. Many epistemologists, however, have higher aspirations and look for reasons or arguments that can justify our factual acceptance of testimony. The inductive argument Hume offers, it is argued, is unconvincing. There is even reason to think that the principle of credulity can never be justified by adducing reasons. This does not imply, however, that acceptance of testimony is unjustified. Whether or not it is depends, among other things, on the concept of justification one uses. On an internalist concept of justification (as Locke's or Hume's) this disposition may never be justified. But on an externalist conception it may. This may be disappointing, given some widely held philosophical aspirations, but at the same time it is, as Alston has said, a lesson in intellectual humility. (shrink)

In this paper, we explore different possible explanations for research misconduct (especially falsification and fabrication), and investigate whether they are compatible. We suggest that to explain research misconduct, we should pay attention to three factors: (1) the beliefs and desires of the misconductor, (2) contextual affordances, (3) and unconscious biases or influences. We draw on the three different narratives (individual, institutional, system of science) of research misconduct as proposed by Sovacool to review six different explanations. Four theories start from the (...) individual: Rational Choice theory, Bad Apple theory, General Strain Theory and Prospect Theory. Organizational Justice Theory focuses on institutional factors, while New Public Management targets the system of science. For each theory, we illustrate the kinds of facts that must be known in order for explanations based on them to have minimal plausibility. We suggest that none can constitute a full explanation. Finally, we explore how the different possible explanations interrelate. We find that they are compatible, with the exception of explanations based on Rational Choice Theory and Prospect Theory respectively, which are incompatible with one another. For illustrative purposes we examine the case of Diederik Stapel. (shrink)

Widely acknowledged as the principal architect of Scottish common sense philosophy, Thomas Reid is increasingly recognized today as one of the finest philosophers of the eighteenth century. Combining a sophisticated response to the skeptical and idealist views of his day, Reid's thought stands as an important alternative to Humean skepticism, Kantian idealism and Cartesian rationalism. This volume is the first comprehensive overview of Reid's output and covers not only his philosophy in detail, but also his scientific work and his extensive (...) historical influence. (shrink)

Degree-sentences, i.e. sentences that seem to refer to things that allow of degrees, are widely used both inside and outside of philosophy, even though the metaphysics of degrees is much of an untrodden field. This paper aims to fill this lacuna by addressing the following four questions: [A] Is there some one thing, such that it is degree sensitive? [B] Are there things x, y, and z that stand in a certain relation to each other, viz. the relation that x (...) has more y than z? [C] In those cases in which degree sentences do not refer to phenomena that are degree sensitive, what is responsible for their prima facie seeming to do so? [D] If there are degree sensitive things, to which ontological categories do they belong? We answer each of these questions by arguing that there are, metaphysically speaking, different phenomena that degree sentences refer to: some refer to determinates that emanate from a certain determinable, others to tokens that are instantiations of a certain type, and yet others to what we call ‘complex, resultant properties that are constituted by stereotypical properties’.

We are ignorant knowers. This paper proposes an information theoretic explanation of that fact. The explanation is a conjunction of three claims. First, that even in those dimensions where we are capable of picking up information, there is information that we don’t pick up. Second, that there can be dimensions of information for which we lack the capacity to pick up any information whatsoever. Third, that we don’t know whether the faculties and cognitive capacities we are endowed with process all (...) the information that they pick up. (shrink)

We present a Reformed view on the relation between Christianity and non-Christian religions. We then explore what this view entails for the question whether Christians and non-Christian religious believers refer to, believe in, and worship the same God. We first analyze the concepts of worship, belief-in, and reference, as well as their interrelations. We then argue that adherents of the Abrahamic religions plausibly refer to the same God, whereas adherents of non-Abrahamic religions do not refer to this God. Nonetheless, it (...) would be wrong to say that adherents of all Abrahamic religions believe in and worship the same God. (shrink)

The humanistic disciplines aim to offer explanations of a wide variety of phenomena. Philosophical theories of explanation have focused mostly on explanations in the natural sciences; a much discussed theory of explanation is the causal theory of explanation. Recently it has come to be recognized that the sciences sometimes offer respectable explanations that are non-causal. This paper broadens the discussion by discussing explanations that are offered in the fields of history, linguistics, literary theory, and archaeology that do not seem to (...) fit the causal theory of explanation. We conducted an exploratory survey in acclaimed humanities textbooks to find explicitly so-called explanations and analyze their nature. The survey suggests that non-causal explanations are an integral part of the humanities and that they are of distinct kinds. This paper describes three kinds that are suggested by our survey: teleological, formal, and normative explanations. We suggest that such humanistic explanations strengthen the case for explanatory pluralism. (shrink)

Though most contemporary philosophers and scientists accept a physicalist view of mind, the recent surge of interest in the problem of consciousness has put the mind/body problem back into play. The physicalists' lack of success in dispelling the air of residual mystery that surrounds the question of how consciousness might be physically explained has led to a proliferation of options. Some offer alternative formulations of physicalism, but others forgo physicalism in favour of views that are more dualistic or that bring (...) in mentalistic features at the ground- floor level of reality as in pan-proto-psychism. My aim here is to give an overview of the recent philosophic discussion to serve as a map in locating issues and options. I will not offer a comprehensive survey of the debate or mark every important variant to be found in the recent literature. I will mark the principal features of the philosophic landscape that one might use as general orientation points in navigating the terrain. I will focus in particular on three central and interrelated ideas: those of emergence, reduction, and nonreductive physicalism. The third of these, which has emerged as more or less the majority view among current philosophers of mind, combines a pluralist view about the diversity of what needs to be explained by science with an underlying metaphysical commitment to the physical as the ultimate basis of all that is real. The view has been challenged from both left and right, on one side from dualists and on the other from hard core reductive materialists. Despite their differences, those critics agree in finding nonreductive physicalism an unacceptable and perhaps even incoherent position. They agree as well in treating reducibility as the essential criterion for physicality; they differ only about whether the criterion can be met. Reductive physicalists argue that it can, and dualists deny it. (shrink)

Ever since at least Aristotle, it has been widely recognized that a theory of responsibility must allow for the fact that in certain conditions agents are excused for not doing what they ought to do —and accordingly that they cannot be held responsible for what they did not, or did, do. In such conditions they are not appropriate candidates for one of what Strawson has called the "reactive attitudes" such as resentment, contempt, gratitude, and affection. Let us call such conditions (...) excusing conditions. The main aim of this paper is to show that the very same conditions that can excuse agents for not doing what they ought to do , also can excuse them for having false beliefs. As an afterthought it is suggested that this is a reason for thinking that humans can sometimes be held responsible for what they believe. (shrink)

This paper argues that next to the now widely recognized ‘externalist’ elements, Reid’s thought about belief with positive epistemic status contains a number of so-far unrecognized ‘internalist’ features. This claim is substantiated by (1) identifying a number of conditions that Reid holds beliefs of various sorts must satisfy if they are to have positive epistemic status, and by (2) arguing that, for Reid, many of these conditions are internal conditions. The conclusion is that the externalist and internalist elements in Reid (...) form a coherent whole and that his position can, with some qualification, be classified as the conjunction of weak externalism and weak internalism.

Is ChatGPT an author? Given its capacity to generate something that reads like human-written text in response to prompts, it might seem natural to ascribe authorship to ChatGPT. However, we argue that ChatGPT is not an author. ChatGPT fails to meet the criteria of authorship because it lacks the ability to perform illocutionary speech acts such as promising or asserting, lacks the fitting mental states like knowledge, belief, or intention, and cannot take responsibility for the texts it produces. Three perspectives (...) are compared: liberalism (which ascribes authorship to ChatGPT), conservatism (which denies ChatGPT's authorship for normative and metaphysical reasons), and moderatism (which treats ChatGPT as if it possesses authorship without committing to the existence of mental states like knowledge, belief, or intention). We conclude that conservatism provides a more nuanced understanding of authorship in AI than liberalism and moderatism, without denying the significant potential, influence, or utility of AI technologies such as ChatGPT.

Contextualists explain certain intuitions regarding knowledge ascriptions by means of the thesis that 'knowledge' behaves like an indexical. This explanation denies what Peter Unger has called invariantism, i.e., the idea that knowledge ascriptions have truth value independent of the context in which they are issued. This paper aims to provide an invariantist explanation of the contextualist's intuitions, the core of which is that 'knowledge' has many different senses.
