Episodic memory is memory for past events. It’s characteristically associated with an experience of ‘mentally replaying’ one’s experiences in the mind’s eye. This biological phenomenon has inspired the development of several ‘experience replay’ algorithms in AI. In this chapter, I ask whether experience replay algorithms might shed light on a puzzle about episodic memory’s function: what does episodic memory contribute to the cognitive systems in which it is found? I argue that experience replay algorithms can serve as idealized models (...) of episodic memory for the purposes of addressing this question. Taking the DQN algorithm as a case study, I suggest that these algorithms provide some support for mnemonic accounts, on which episodic memory’s function lies in the storage, encoding and retrieval of information. By extending and adapting experience replay algorithms, we might gain further insight into episodic memory’s operations and contributions to cognition. (shrink)

We analyze a series of interviews with Estonian humanities researchers to explore topics related to the beginning of academic careers and the relationships with supervisors and mentors. We show how researchers strive to have meaningful relationships and produce what they consider quality research in the conditions of a system that is very strongly oriented towards internationalization and project-based funding, where their efforts are compromised by a lack of policies helping them establish a stable position in academia. Leaving researchers to face (...) these obstacles alone places a great burden on them and may lead to a loss of talent in academia. Identifying and addressing these issues is thus important for both the well-being of early career researchers and the future of academia. (shrink)

The results revealed that students who remained in China experienced challenges which included anxiety, closure of campuses, lockdown, their parents’ concern regarding health issues, and not being able to meet with friends. On the other hand, students who had left China during the pandemic were confined to their home countries. This group of students experienced more severe problems than the students who remained in China. Since the transition to home countries was “unplanned,” they were not ready to readjust to their (...) native culture and were vulnerable to severe reverse culture shock. Upon returning to their home countries, international students faced a number of challenges, including readjustment to their home countries and changes in their lives in host and home countries. In addition, they lost social and academic resources, such as the disruption of study environment, losing important group memberships, financial constraints, visa expiry, graduation delay, and academic suspension.

Modular learning was used to assist elementary learners in continuing their education during the pandemic. This modular learning posed academic challenges. This phenomenological study delved into the academic challenges of modular learning of public-school elementary school learners. Validated In-depth interview protocol (IDI) was used to collect the data from ten (10) Grade six learners. Findings revealed that these academic challenges include unfavorable learning environments, reading comprehension issues, lack of motivation, and poor quality of printed learning modules that affect the learners (...) ability to comprehend and finish the module effectively. Consequently, modular learning allows learners to take responsibility for their learning by utilizing the available answers key, optimizing internet usage, scheduling time properly, and guessing answers. Considerably, the learners used face-to-face conversations, personal messages, and phone calls to communicate their educational queries. Moreover, the structure of self-learning modules facilitates independent study and complicates learners understanding. It is recommended that there is a need to enhance policies for improving module quality, allocate sufficient funds to improve the printed module quality, conduct relevant teacher training and workshops for developing quality printed modules, and sustain the home visitation program to monitor students modular learning progress.

The essay problematizes the incorporation of LGBTI rights promotion into the US and EU foreign policies. First, the paper examines the two actors’ key documents, speeches, and policies devoted to the promotion of LGBTI rights abroad, the similarities and differences between the two actors’ approaches, attending to the tendencies of their evolution and the ongoing development. Second, the article discusses the internal conditions in target countries that are conducive to the success and failure of international support of LGBTI rights. Finally, (...) the study makes a critical overview of the measures that are argued to be necessary to increase the efficiency of LGBTI rights promotion in countries with most negative current trends in and/or poorest records on LGBTI rights.

We explore the role of episodic imagining in explaining why people both differentially report that it seems to them in experience as though time robustly passes, and why they differentially report that they believe that time does in fact robustly pass. We empirically investigate two hypotheses, the differential vividness hypothesis, and the mental time travel hypothesis. According to each of these, the degree to which people vividly episodically imagine past/future states of affairs influences their tendency to report that it seems (...) to them as though time robustly passes and to judge that time does robustly pass. According to the former, a greater degree of vividness will tend to increase the extent to which people make such reports, while according to the latter, it will tend to decrease the extent to which people make such reports. We found weak evidence in favour of the former hypothesis. We reflect on the implications of this finding for theorising about such reports. (shrink)

Designing a virtual environment within a digital game occupies a large part of the design procedure, requiring holistic attention and a broad arrangement of the game constituents. Considering other design disciplines, they occupy a unified design methodology; however, a comprehensive literature review reveals the lack of the intended design methodology in the digital game domain's virtual environment development, despite a currently proposed theoretical methodology trying to dissolve the issue. Hence, this research aims to determine the industry's requirements and provide a (...) set of assets included in current digital games as an initial step of providing such a design methodology for the domain. In this regard, the researchers reverse-engineered ten selected digital games, understanding the current condition of digital games via adopting the mentioned currently available design methodology. This dataset reveals a lack in the assets of the story layer in the recent digital games, despite their focus on being story-based. This dilemma leads to long text or speech conversations between game characters, disrupting the players while following the game. The current design focuses on environmental resources only, however, as a virtual landscape, the story needs to be reinforced to be a balanced and well-designed game. Hence, increasing the ratio of the assets in this layer will advance the games' interactivity. Also, as future work, this data set could pave the way for a digital game industry design tool regarding the virtual environment. (shrink)

This paper is part of a book symposium for L. A. Paul (2014) Transformative Experience (OUP).

Many people have recently argued that we need to distinguish between experiences and seemings and that this has consequences for views about how perception provides evidence. In this article I spell out my take on these issues by doing three things. First, I distinguish between mere sensations like seeing pitch black all around you and perceptual experiences like seeing a red apple. Both have sensory phenomenology in presenting us with sensory qualities like colors, being analog in Dretske's sense, (...) and being fine-grained. However, only the latter have furthermore a perceptual phenomenology characterized by objectification and related dualities of perspectivality/completion and variation/constancy. Second, I elaborate on the reasons for thinking that both mere sensations and perceptual experiences need to be distinguished from accompanying seemings that passively assign things into conceptual categories and thereby tell you something about them. For example, when you look at a red apple and have the relevant recognitional abilities it will also normally seem to you that this is an apple. Finally, I argue that the best version of the popular dogmatist view about evidence is one which claims that it's neither experiences nor seemings by themselves, but rather the right sorts of composites of experiences and seemings that provide evidence.

Metaphysical theories are often counter-intuitive. But they also often are strongly supported and motivated by intuitions. One way or another, the link between intuitions and metaphysics is a strong and important one, and there is hardly any metaphysical discussion where intuitions do not play a crucial role. In this article, I will be interested in a particular kind of such intuitions, namely those that come, at least partly, from experience. There seems to be a route from experience to metaphysics, and (...) this is the core of my interest here. In order to better understand such ‘arguments from experience’ and the kind of relationship there is between this type of intuitions and metaphysical theories, I shall examine four particular cases where a kind of experience-based intuition seems to motivate or support a metaphysical theory. At the end of the day, I shall argue that this route is a treacherous one, and that in all of the four cases I shall concentrate on, phenomenological considerations are in fact orthogonal to the allegedly ‘corresponding’ metaphysical claims. An anti-realist view of metaphysics will emerge. (shrink)

It seems like experience plays a positive—even essential—role in generating some knowledge. The problem is, it’s not clear what that role is. To see this, suppose that when your visual system takes in information about the world around you it skips the experience step and just automatically and immediately generates beliefs in you about your surroundings. A lot of philosophers think that, in such a case, you would (or at least could) still know, via perception, about the world around you. (...) But then that raises the question: What epistemic role was the experience playing? How did it contribute to your knowledge of your surroundings? Philosophers have given many different answers to these questions. But, for various reasons, none of them has really stuck. In this paper I offer and defend a different answer to these questions—a solution to the problem—which avoids the pitfalls of other answers. I argue that experience is, all by itself, a kind of knowledge—it’s what Bertrand Russell (1912) calls “knowledge of things”. So I argue that experience helps generate knowledge simply by being knowledge. (shrink)

What is the role of affective experience in explaining how our desires provide us with reasons for action? When we desire that p, we are thereby disposed to feel attracted to the prospect that p, or to feel averse to the prospect that not-p. In this paper, we argue that affective experiences – including feelings of attraction and aversion – provide us with reasons for action in virtue of their phenomenal character. Moreover, we argue that desires provide us with (...) reasons for action only insofar as they are dispositions to have affective experiences. On this account, affective experience has a central role to play in explaining how desires provide reasons for action. (shrink)

I assess a number of connected ideas about temporal experience that are introspectively plausible, but which I believe can be argued to be incorrect. These include the idea that temporal experiences are extended experiential processes, that they have an internal structure that in some way mirrors the structure of the apparent events they present, and the idea that time in experience is in some way represented by time itself. I explain how these ideas can be developed into more sharply (...) defined views, and then argue that these views are inconsistent with certain empirical facts about how time is represented in the brain. These facts instead support a kind of atomic view, on which temporal experiences are temporally unstructured atoms. (shrink)

In this paper, I reconstruct Robert Nozick's experience machine objection to hedonism about well-being. I then explain and briefly discuss the most important recent criticisms that have been made of it. Finally, I question the conventional wisdom that the experience machine, while it neatly disposes of hedonism, poses no problem for desire-based theories of well-being.

First published in 1949 expressly to introduce logical positivism to English speakers. Reichenbach, with Rudolph Carnap, founded logical positivism, a form of epistemofogy that privileged scientific over metaphysical truths.

Thought experiments play a role in science and in some central parts of contemporary philosophy. They used to play a larger role in philosophy of science, but have been largely abandoned as part of the field’s “practice turn”. This chapter discusses possible roles for thought experimentation within a practice-oriented philosophy of science. Some of these roles are uncontroversial, such as exemplification and aiding discovery. A more controversial role is the reliance on thought experiments to justify philosophical claims. It is proposed (...) that if we adopt an underlying empiricist view of concepts, then thought experiments can be seen as affording us contact with scientific practice, despite their seemingly a priori character. The advantages and drawbacks of thought experiments are discussed via comparison with case studies, on the one, and simulations on the other hand. The chapter closes with some remarks on how to combine thought experiments with other methods. (shrink)

Water is regarded as indefeasible necessity of human civilization. In the South Asia region, the groundwater resource is poised as essence of life, security and development. Bangladesh is not an exception from that. Due to scarcity as well as disproportionate availability of surface water supply, the groundwater resource is veered into vital source to undergird heavy demand of water supply for livelihoods, industrial and agricultural purposes. Considering these, the groundwater resource governance is crucial since it is the mainstay of upholding (...) economic, social and development rights; failure to ensure proper governance would only drag the country into the tentacles of environmental scourge, conflict and food insecurity. The paper endeavors to analyze the role and significance of civil society on groundwater resource management. It explores the nature of challenges that civil society is encountering during its engagement with groundwater resource governance. This paper undertakes to outline national legislative and policy response to groundwater resource management in Bangladesh. It also scrutinizes in detail of groundwater resource aspect in international law and would reveal that, considering the gravity of the issue, both the domain of international law and national law contribute below the par to the issue. The paper further contends that existing legislative and policy structure of Bangladesh eventually maims the civil society from contributing and bars it to facilitate effective participation of the commons. In the concluding remarks, the paper highlights suggested recommendations stemming from discussions, observations and policy reports to bolster the affiliation of civil society in the governance of groundwater resource.

It is argued that Nozick's experience machine thought experiment does not pose a particular difficulty for mental state theories of well-being. While the example shows that we value many things beyond our mental states, this simply reflects the fact that we value more than our own well-being. Nor is a mental state theorist forced to make the dubious claim that we maintain these other values simply as a means to desirable mental states. Valuing more than our mental states is compatible (...) with maintaining that the impact of such values upon our well-being lies in their impact upon our mental lives. (shrink)

This paper explores how transformative experience generates decision-making problems of particular seriousness in medical settings. Potentially transformative experiences are especially likely to be encountered in medicine, and the associated decisions are confronted jointly by patients and clinicians in the context of an imbalance of power and expertise. However in such scenarios the principle of informed consent, which plays a central role in guiding clinicians, is unequal to the task. We detail how the principle’s assumptions about autonomy, rationality and information (...) handle transformative experiences poorly, appealing to several difficult cases for medical decision-making to illustrate the resulting problem, and we consider how the existing literature on complications with consent fails to offer a resolution. We argue that recognition of the problem has a role to play in achieving a more effective response to transformative decisions. In Sect. 1 we introduce several representative cases of challenging patient decision-making that clinicians might face. In Sect. 2 we detail how transformative experience has been analysed in the recent literature, before outlining in Sect. 3 the theoretical basis of the principle of informed consent, which plays a central role in how clinicians are expected to support decision-making. In Sect. 4, having laid the groundwork for a clear description, we return to the cases given in Sect. 1 to confirm how their transformative nature presents a problem: either clinicians treat the decisions faced by these patients as ‘normal’, encouraging them to focus on information provision that patients may be unable to act on, or they treat them as transformative, in which case they lack the resources to recognise whether they are helping patients make (subjectively) good decisions. In Sect. 5 we argue that the existing literature does not offer any escape from this problem. We close in Sect. 6 by noting the significant impact that appreciating the problem of transformative experience could have on supporting transformative decisions in medicine and briefly suggesting how we might aim to develop new approaches to dealing with these.

Much of the recent movement organized under the heading “Experimental Philosophy” has been concerned with the empirical study of responses to thought experiments drawn from the literature on philosophical analysis. I consider what bearing these studies have on the traditional projects in which thought experiments have been used in philosophy. This will help to answer the question what the relation is between Experimental Philosophy and philosophy, whether it is an “exciting new style of [philosophical] research”, “a new interdisciplinary field that (...) uses methods normally associated with psychology to investigate questions normally associated with philosophy” (Knobe et al. 2012), or whether its relation to philosophy consists, as some have suggested, in no more than the word ‘philosophy’ appearing in its title, or whether the truth lies somewhere in between these two views. I first distinguishes different strands in Experimental Philosophy, negative and positive x-phi, and x-phi pursuing philosophy as opposed to x-phi as cognitive science. Next I review some ways in which Experimental Philosophy has been criticized. Finally, I consider what would have to be true for Experimental Philosophy to have one or another sort of relevance to philosophy, whether the assumptions required are true, how we could know it, and the ideal limits of the usefulness Experimental Philosophy to philosophy. I conclude x-phi cannot in principle be a replacement for traditional first person approaches because it yields the wrong kind of knowledge and that it can nonetheless be a practical aid in conducting philosophical thought experiments. n.

According to the recent Perceptual Confidence view, perceptual experiences possess not only a representational content, but also a degree of confidence in that content. The motivations for this view are partly phenomenological and partly epistemic. We discuss both the phenomenological and epistemic motivations for the view, and the resulting account of the interface between perceptual experiences and degrees of belief. We conclude that, in their present state of development, orthodox accounts of perceptual experience are still to be favoured (...) over the perceptual confidence view. (shrink)

I offer an account of the experience of acting that demonstrates how agentive aspects of experience associated with the execution of intentions are richly integrated with perceptual aspects associated with parts of action taking place in the publicly observable world. On the view I elucidate, the experience of acting is often both an engagement with the world and a type of intimate acquaintance with it. In conscious action the agent consciously intervenes in the world and consciously experiences the world (...) she is changing. In section one, I discuss extant accounts of the experience of acting, noting deficiencies. In sections two and three, I develop my own account, drawing on Casey O’Callaghan’s work on multi-modal perception. In the conclusion, I discuss ramifications for psychology and philosophy. (shrink)

to appear in Lambert, E. and J. Schwenkler (eds.) Transformative Experience (OUP) -/- L. A. Paul (2014, 2015) argues that the possibility of epistemically transformative experiences poses serious and novel problems for the orthodox theory of rational choice, namely, expected utility theory — I call her argument the Utility Ignorance Objection. In a pair of earlier papers, I responded to Paul’s challenge (Pettigrew 2015, 2016), and a number of other philosophers have responded in similar ways (Dougherty, et al. 2015, (...) Harman 2015) — I call our argument the Fine-Graining Response. Paul has her own reply to this response, which we might call the Authenticity Reply. But Sarah Moss has recently offered an alternative reply to the Fine-Graining Response on Paul’s behalf (Moss 2017) — we’ll call it the No Knowledge Reply. This appeals to the knowledge norm of action, together with Moss’ novel and intriguing account of probabilistic knowledge. In this paper, I consider Moss’ reply and argue that it fails. I argue first that it fails as a reply made on Paul’s behalf, since it forces us to abandon many of the features of Paul’s challenge that make it distinctive and with which Paul herself is particularly concerned. Then I argue that it fails as a reply independent of its fidelity to Paul’s intentions. (shrink)

Paul (2014, 2015a) argues that one cannot rationally decide whether to have a transformative experience by trying to form judgments, in advance, about (i) what it would feel like to have that experience, and (ii) the subjective value of having such an experience. The problem is if you haven’t had the experience then you cannot know what it is like, and you need to know what it is like to assess its value. However, in earlier work I argued that ‘what (...) it is like’-knowledge comes in degrees, and I briefly suggested that, consequently, some instances of Paul’s argument schema might commit a fallacy of equivocation. The aim of this paper is to further explore and strengthen this objection by, first, offering a new argument—the modelling argument—in support of it, and then by evaluating a range of replies that might be given to this objection on Paul’s behalf. I conclude that each reply either fails or, at best, only partially succeeds in defending some but not all instances of Paul’s argument schema. In closing, I consider how we might revise Paul’s concepts of transformative experiences and choices in response to this conclusion. (shrink)

This chapter discusses some aspects of the relation between temporal experience and the A versus B debate. To begin with, I provide an overview of the A versus B debate and, following Baron et al. (2015), distinguish between two B-theoretic responses to the A- theoretic argument from experience, veridicalism and illusionism. I then argue for veridicalism over illusionism, by examining our (putative) experiences as of presentness and as of time passing. I close with some remarks on the relation between (...) veridicalism and a deflationary view of the A versus B debate. I suggest that the deflationary view can provide further support for veridicalism. (shrink)

Sometimes it is not us but those to whom we stand in special relations that face transformative choices: our friends, family, or beloved. A focus upon first-personal rational choice and agency has left crucial ethical questions regarding what we owe to those who face transformative choices largely unexplored. In this paper, I ask: under what conditions, if any, is it morally permissible to interfere with to try to prevent another from making a transformative choice? Some seemingly plausible answers to this (...) question fail precisely because they concern transformative experiences. I argue that we have a distinctive moral right to revelatory autonomy grounded in the value of autonomous self-making. If this right is outweighed then, I argue, interfering to prevent another making a transformative choice is permissible. This conditional answer lays the groundwork for a promising ethics of transformative experience. (shrink)

I open my eyes and see that the lemon before me is yellow. States like this—states of seeing that $p$ —appear to be visual perceptual states, in some sense. They also appear to be propositional attitudes (and so states with propositional representational contents). It might seem, then, like a view of perceptual experience on which experiences have propositional representational contents—a Propositional View—has to be the correct sort of view for states of seeing that $p$ . And thus we can’t (...) sustain fully general non-Propositional but Representational, or Relational Views of experience. But despite what we might initially be inclined to think when reflecting upon the apparent features of states of seeing that $p$ , a non-propositional view of seeing that $p$ is, I argue, perfectly intelligible.

It is argued that the hard problem of consciousness, i.e. the fact that we have experience, stems from a conceptual confusion between consciousness and experience. It is concluded that experience has to be considered as a basic characteristic of ongoing interactions at even the most simple level, while consciousness is better defined as reflexive awareness, possible since symbolic language was developed. A dynamic evolutionary point of view is proposed to make more appropriate distinctions between experience, awareness and consciousness. Experience can (...) be defined as a characteristic linked closely to specific pattern matching, a characteristic which is already apparent at the molecular level at least. Awareness then can be regarded as the special experience of one or more central, final modules in the animal neuronal brain. From evolutionary considerations, awareness can be understood functionally and physiologically. As such, awareness is what experience is to animals. Finally, consciousness could be defined as reflexive awareness, instead of using the term as synonymous to awareness. The ability for reflexive awareness is distinctly different from animal and human awareness and depends upon the availability of a separate frame of reference, as provided by symbolic language. As such, words have made reflexive awareness - a specific and infrequent form of awareness - possible. Conciousness might be defined as the experience evoked by considering, i.e. thinking about experiences themselves. Explaining and understanding awareness and consciousness as evolved biological characteristics of the functioning of animals and later humans, poses no philosophical problems. The nature of experience itself remains elusive, but this is not a problem specific toawareness or consciousness. If there is a hard problem of explaining consciousness, than this actually must be considered as the hard problem of explaining experience. While the definition of experience could be broadened to include all molecular and biological pattern specific recognition events, the true nature of consciousness might be better understood when considering it as a very specific form of awareness, made possible by language.

Those arguing for the existence of non-propositional content appeal to emotions for support, although there has been little engagement in those debates with developments in contemporary theory of emotion, specifically in connection with the kind of mental states that emotional experiences are. Relatedly, within emotion theory, one finds claims that emotional experiences per se have non-propositional content without detailed argument. This paper argues that the content of emotional experience is propositional in a weak sense, associated with aspectual experience (...) and correctness conditions. Furthermore, it provides an interpretation of purely-objectual emotional experiences which satisfies this weak view of propositional content. (shrink)

In my dissertation, I develop a novel approach to thought experiments and literary learning. It’s novel primarily because, unlike many prominent approaches, it has us refrain from advancing theories, from giving logical analyses, and from explicating. We are, instead, to proceed in a way inspired by Wittgenstein’s writings. We are, that is, to clarify words that give rise to problems and to clear those problems away. To clarify words, we may compare language games in which figure terms like “thought experiment.” (...) Thereby, we might see that the concept these terms express has a family resemblance character. To clear away problems, we may describe how such a concept, if not illuminated, yields philosophical problems about thought experiments and literary learning. -/- After I develop this approach, I bring it to bear on two problems, and I achieve two main results. One problem concerns the nature of thought experiments. It is: Why do we have trouble explaining what we know them to be? I find that, despite appearances, we have no such trouble. Central to this result are two claims about thought experiments. One is that imaginings aren’t common to them. The other is that our unreflective concept of them has a family resemblance character. -/- The other problem concerns stories in works of literary fiction. It is: How could we possibly learn about the world from them? To solve it, you might claim that we learn by performing thought experiments, and then appeal to a theory of them. I find that you’d risk explaining the wrong thing. That is, you may well explain only how we learn—not how we do so from literature itself. Central to this result are three claims, which concern how these stories differ from thought experiments. They differ, I claim, (i) in how we count imaginings as experiences of them, (ii) in how free we are to interpret them, and (iii) in how complex they may be. This done, I’ve twice taken my novel approach and achieved results. (shrink)

Although thought experiments were first discovered as a sui generis methodological tool by philosophers of science (most prominently by Ernst Mach), the tool can also be found – even more frequently – in contemporary philosophy. Thought experiments in philosophy and science have a lot in common. However, in this chapter we will concentrate on thought experiments in philosophy only. Their use has been the centre of attention of metaphilosophical discussion in the past decade, and this chapter will provide an overview (...) of the results this discussion has achieved and point out which issues are still open.

In this article I explore various facets of Nozick’s famous thought experiment involving the experience machine. Nozick’s original target is hedonism—the view that the only intrinsic prudential value is pleasure. But the argument, if successful, undermines any experientialist theory, i.e. any theory that limits intrinsic prudential value to mental states. I first highlight problems arising from the way Nozick sets up the thought experiment. He asks us to imagine choosing whether or not to enter the machine and uses our choice (...) (or rather the choice he assumes most people will have) as evidence against experientialist theories. But for this strategy to succeed it must be possible to distinguish between self-interested and non-self-interested reasons for declining to enter the machine, and there is no obvious way to do this without begging the question against the hedonist. In successive sections I then (a) consider a common misconception of Nozick’s conclusion (that he thinks machine life is the worst life), (b) consider different intuitions about what is important to well-being but missing from machine life, and finally (c) explain what “the experience requirement” is, and describe its relationship to debates about experientialist theories.

In current debates on Descartes’ metaphysics of the mind, the question tends to be whether his position is that of a libertarian or of a compatibilist concerning the freedom of the will. I intervene in this discussion by focusing on the experience of choosing freely. To do this I take a closer look at the 'feeling of not being determined by external forces', an up to now too little discussed passage of the 'Fourth Meditation'. In successively considering God, an evil (...) genius and the faculty of understanding as external forces acting on the will, I show how Descartes’ discussion of freedom of choice implicates both his ethical and epistemological ambitions in a way that could benefit the libertarian-compatibilist debate. To determine the nature of the freedom of will in Descartes, one may not only discuss the causality of the operations of the will, but also the perception of this causality by the mind, in other words, the experience of freedom.

Unlike in physics, the category of thought experiment is not very common in biology. At least there are no classic examples that are as important and as well-known as the most famous thought experiments in physics, such as Galileo’s, Maxwell’s or Einstein’s. The reasons for this are far from obvious; maybe it has to do with the fact that modern biology for the most part sees itself as a thoroughly empirical discipline that engages either in real natural history or in (...) experimenting on real organisms rather than fictive ones. While theoretical biology does exist and is recognized as part of biology, its role within biology appears to be more marginal than the role of theoretical physics within physics. It could be that this marginality of theory also affects thought experiments as sources of theoretical knowledge. Of course, none of this provides a sufficient reason for thinking that thought experiments are really unimportant in biology. It is quite possible that the common perception of this matter is wrong and that there are important theoretical considerations in biology, past or present, that deserve the title of thought experiment just as much as the standard examples from physics. Some such considerations may even be widely known and considered to be important, but were not recognized as thought experiments. In fact, as we shall see, there are reasons for thinking that what is arguably the single most important biological work ever, Charles Darwin’s On the Origin of Species, contains a number of thought experiments. There are also more recent examples both in evolutionary and non-evolutionary biology, as we will show. Part of the problem in identifying positive examples in the history of biology is the lack of agreement as to what exactly a thought experiment is. Even worse, there may not be more than a family resemblance that unifies this epistemic category. We take it that classical thought experiments show the following characteristics: They serve directly or indirectly in the non-empirical epistemic evaluation of theoretical propositions, explanations or hypotheses. Thought experiments somehow appeal to the imagination. They involve hypothetical scenarios, which may or may not be fictive. In other words, thought experiments suppose that certain states of affairs hold and then try to intuit what would happen in a world where these suppositions are true. We want to examine in the following sections if there are episodes in the history of biology that satisfy these criteria. As we will show, there are a few episodes that might satisfy all three of these criteria, and many more if the imagination criterion is dropped or understood in a lose sense. In any case, this criterion is somewhat vague in the first place, unless a specific account of the imagination is presupposed. There will also be issues as to what exactly “non-empirical” means. In general, for the sake of discussion we propose to understand the term “thought experiment” here in a broad rather than a narrow sense here. We would rather be guilty of having too wide a conception of thought experiment than of missing a whole range of really interesting examples. (shrink)

I argue that perceptual experience provides us with both phenomenal and factive evidence. To a first approximation, we can understand phenomenal evidence as determined by how our environment sensorily seems to us when we are experiencing. To a first approximation, we can understand factive evidence as necessarily determined by the environment to which we are perceptually related such that the evidence is guaranteed to be an accurate guide to the environment. I argue that the rational source of both phenomenal and (...) factive evidence lies in employing perceptual capacities that we have in virtue of being perceivers. In showing that both kinds of evidence have the same rational source, I provide a unified account of perceptual evidence and its rational source in perceptual experience. (shrink)

In the early twentieth century, many philosophers in America thought that time should be taken seriously in one way or another. George P. Adams (1882-1961) argued that the past, present and future are all real but only the present is actual. I call this theory ‘actualist eternalism’. In this paper, I articulate his novel brand of eternalism as one piece of his metaphysical system and I explain how he argued for the view in light of the best explanations of temporal (...) experience and the present. I argue that his exploitation of analogies between time and modality offer some lessons for current debates about time such as the importance of providing a temporal epistemology. I also extract what I call the temporal boundary problem and argue that it gives rise to an unaddressed challenge for presentists and growing block theorists. (shrink)

The main question that we address in this chapter is what to say about reportedly libertarian experiences of free agency – in other words, experiences of options as being open, and up to oneself to decide among, such that, if they are accurate or veridical, then (at a minimum) indeterminism must be true. A great deal rides on this question. If normal experiences of free agency are libertarian, and if compatibilists cannot explain them away, then all of (...) us may be under systematic illusion at almost every moment of our waking lives. That is, our experiences would be illusory if humans do not in fact satisfy libertarian conditions (e.g., if indeterminism does not occur in the right time or place during decision-making, or we lack agent-causal powers). In some sense, more rides on the question of whether we are agents of the sort that we experience ourselves as being than on the question of whether we have the type of control required for moral responsibility. At worst, we are not responsible in only one sense if we lack what libertarians say we need. Yet even then, we would not be under systematic experiential illusion during most of our waking lives, as we are if our experience is libertarian, yet false. (shrink)

I examine the role of inference from experiment in theory building. What are the options open to the scientific community when faced with an experimental result that appears to be in conflict with accepted theory? I distinguish, in Laudan's (1977), Nickels's (1981), and Franklin's (1993) sense, between the context of pursuit and the context of justification of a scientific theory. Making this distinction allows for a productive middle position between epistemic realism and constructivism. The decision to pursue a new or (...) a revised theory in response to the new evidence may not be fully rationally determined. Nonetheless, it is possible to distinguish the question of whether there is reason to pursue a theory from the question of whether that theory, once it has been pursued over time, solves a problem of interest to science. I argue that, in this context, there is a solid way to distinguish between the contexts of pursuit and of justification, on the basis of a theory's evidential support and problem-solving ability.

It is widely presumed that intuitions about thought experiments can help overturn philosophical theories. It is also widely presumed, albeit implicitly, that if thought experiments play any epistemic role in overturning philosophical theories, it is via intuition. In this paper, I argue for a different, neglected epistemic role of philosophical thought experiments, that of improving some reasoner’s appreciation both of what a theory’s predictions consist in and of how those predictions tie to elements of the theory. I call this role (...) theory clarification. I show that theory clarification does not proceed via intuition, and I argue that it is only in conjunction with theory clarification that intuitions about thought experiments can help overturn philosophical theories. I close by sketching how a more radical view might be true, on which thought experiments help justify the rejection of philosophical theories exclusively by clarifying theories, not by any intuitions those thought experiments might generate.

This paper starts by distinguishing three views about the phenomenal character of perceptual experience. ‘Low-level theorists’ argue that perceptual experience is reducible to the experience of low-level properties, ‘high-level theorists’ argue that we have perceptual experiences of high-level properties, while ‘disunified view theorists’ argue that perceptual seemings can present high-level properties. The paper explores how cognitive states can penetrate perceptual experience and provides an interpretation of cognitive penetration that offers some support for the high-level view.

Ian Hacking’s Representing and Intervening is often credited as being one of the first works to focus on the role of experimentation in philosophy of science, catalyzing a movement which is sometimes called the “philosophy of experiment” or “new experimentalism”. In the 1980s, a number of other movements and scholars also began focusing on the role of experimentation and instruments in science. Philosophical study of experimentation has thus seemed to be an invention of the 1980s whose central figure is Hacking. (...) This article aims to assess this historical claim, made by Hacking himself as well as others. It does so first by highlighting how a broader perspective on the history of philosophy reveals this invention narrative to be incorrect, since experimentation was a topic of interest for earlier philosophers. Secondly, the article evaluates a revision of this historical claim also made by some philosophers of experiment: the rediscovery narrative, which frames Hacking and others as having rediscovered the work of these earlier authors. This second narratives faces problems as well. Therefore we develop a third narrative which we call the contextualist narrative. Rather than considering experimentation in an essentialist manner as a fixed research object that is either present or not in the work of specific authors, experimentation should be addressed through a narrative that asks in what way it becomes a philosophical problem for certain authors and for what purpose. Such contextualization enables a repositioning of Hacking’s philosophy of experiment in relation to the specific debates in which he intervened, such as the realism-antirealism debate, the Science Wars and the debate on incommensurability.

The question I want to explore is whether experience supports an antireductionist ontology of time, that is, whether we should take it to support an ontology that includes a primitive, monadic property of nowness responsible for the special feel of events in the present, and a relation of passage that events instantiate in virtue of literally passing from the future, to the present, and then into the past.

The family is a social group. Its characteristics are among other things; common residence, co-operation and reproduction. The family has always been considered to be the foundation or nucleus of the society; the most basic unit of its organization. The structure of the family varies according to each society. In pre-colonial era, the family as a social group among the Yorùbá, was a large unit, and extended in nature. They were bound together by the realization of having a common ancestor; (...) alájọbí. All the members of the family see one another as blood relations, as such incest was (and still is) a taboo. Apart from this, sexual relationship among the Yorùbá is heterosexual and permissible only in marriage; between husband and his wife/wives. Though extra-marital relationships are practiced, it is frowned at for men, but intolerable for women. Homosexuality is also a taboo; punishable by public disgrace, with culprits liable to excommunication from the society, especially if unrepentant. It cannot be totally ruled out that these anomalous relationships were not secretly engaged in by few non-conformists among the Yorùbá, before coming into contact with the West, the fact remains that the magnitude by which they are practiced in present times is alarming; threatening the harmony and cultural heritage of the Yorùbá. This fear is expressed in the literary genres of the Yorùbá, especially the film, which is the contemporary popular theatre of the Yorùbá of Nigeria and other tribes in Africa. This study examined sexual relationship among members of the family, in randomly selected Yorùbá films that have family-living as their major or minor themes; to know how affected is the stability of family (sexual) relationship among the Yorùbá. This is in the light of evolving modernity; with its individualistic life-style of people globally, as against the inherited communal social organization of the Yorùbá; built around the virtuous ọmọlúwàbí principle. The plausible reasons for the anomalous behaviors are also examined. Our findings are that prevailing strict traditional conditions, living in private homes as nuclear family, not being properly oriented in Yorùbá cultural values, increased exposition to Western lifestyles and its more relaxed societal expectations, and non-realization of the possibility of anomalous sexual behaviors as mental and biological issues that can be medically treated; are some of the reasons why such behaviors manifest, and are becoming prevalent. We have suggested communal encouragement with empathy, to seek medical assistance for and by the ‘diseased’ person. One finding here is that prevailing traditional conditions, ignorance, poor orientation and westernization present the anomaly mildly and make people not to see anomalous sex behavious as a mental disorder which requires medical attention.

One central fact about hallucinations is that they may be subjectively indistinguishable from perceptions. Indeed, it has been argued that the hallucinatory experiences concerned cannot— and need not—be characterized in any more positive general terms. This epistemic conception of hallucinations has been advocated as the best choice for proponents of experiential (or “naive realist”) disjunctivism—the view that perceptions and hallucinations differ essentially in their introspectible subjective characters. In this chapter, I aim to formulate and defend an intentional alternative to (...) experiential disjunctivism called experiential intentionalism. This view not only enjoys some advantages over its rival but is also compatible with the epistemic conception of hallucinations, as well as with the disjunctivist view that perceptions and hallucinations differ essentially in their third-personal structures (e.g., their causal, informational, or reason-providing links to reality). It also maintains that there are actually two aspects to the subjective indistinguishability of mental episodes: (i) we cannot distinguish their first-personal characters in introspective awareness; and (ii) we cannot distinguish their third-personal structures in experiential awareness—that is, in how they are given to consciousness. While experiential disjunctivism makes the mistake of ignoring (ii) and reducing subjective indiscriminability to (i), experiential intentionalism correctly identifies (ii) as the primary source of the subjective indistinguishability of perception-like hallucinations. Accordingly, the intentional error involved in such hallucinations is due to the fact that we consciously experience them as possessing a relational structure. (shrink)

Recently, psychologists have started to distinguish between three kinds of experience of meaning. Drawing on philosophical as well as empirical literature, I argue that the experience of one’s own life making sense involves a sense of narrative justification, so that not just any kind of intelligibility suffices; the experience of purpose includes enthusiastic future-directed motivation against the background of a global sort of hopefulness, or the resonance of what one does right now with one’s values; and finally, the experience of (...) significance consists primarily of feelings of pride and fulfilment, which construe our actions as making a positive difference to the world or as mattering to someone who matters to us. Mutually exclusive philosophical views of what makes our lives meaningful could all be simultaneously correct about the fittingness of these different kinds of experience. (shrink)
