When we abandon the neoliberal fiction that one is independent on the grounds that it is a-historic and antisocial, we realize that everyone is dependent and interdependent. In a media-driven society the self-identity of the individual is formed within the framework of the culture-ideology of consumerism from early childhood. As a result, both the environmental and social destruction have intensified. In the global era, or in the era of the global environmental crisis, self-identity as a precondition for environmentally sustainable care (...) of the self should be based on the culture-ideology of human rights and responsibilities, and on conscious self-limitation which realizes that one’s prosperity and security cannot come at the expense of others. Care of the self is about ensuring the habitability of the global environment as the primary interest of each individual. (shrink)

Tourism is one of the socio-economic trends that significantly contributes to the shift of the planetary system into the Anthropocene regime. At the same time, it is also a socio-cultural practice characteristic of the imperial mode of living, or consumerism. Thus, it is a form of commodification of nature, also a way of deepening social inequalities between a privileged minority of the global population and an exploited majority providing services to those whose socio-economic status allows them to travel for fun (...) and commoditised “experience”. This is not an inevitable activity, an activity in which environmental costs (carbon footprint, water footprint, energy consumption, and waste production) are necessary to ensure the basic resources of life. Tourism is therefore a form of luxury consumption. For any tourism model to be, not only, environmentally sustainable but also socially just, or at least acceptable, it would have to be accessible to all people. Ecotourism should also have to meet the criterion of a solidarity mode of living referred to as sufficiency. This is hardly conceivable in the climatic, demographic, and political regime of the Anthropocene. The latter is likely to be characterized by, among other things, mass migration of climate or environmental refugees on the one hand and climate apartheid of the states of the global North on the other. Ecotourism, accessible to an even smaller proportion of the world`s population than the current mass tourism, will thus be more likely to accentuate the social and environmental inequalities of which it is already a significant manifestation. Therefore, the question is whether the concept of ecotourism is not just another manifestation of greenwashing, i.e. an attempt to legitimize economic, social, and cultural activities that devastate the social and environmental environment.

The aim of this study is to identify the key terms and arguments of J. Lovelock՚s sustainable retreat concept and their analysis with emphasize on the consequences of this concept for political, social and environmental thinking. J. Lovelock points out that considering rapid and complex changes in global environment, marked by the term Anthropocene; we do not have enough time and sources to realize the sustainable development concept. For that reason, it is, according to him, necessary to formulate sustainable retreat (...) concept as a strategy which will allow to prepare for climate change in a way that not only a man as a biological specie, but also civilized society could survive. Even basic theses of this concept indicate a need to revalue majority political concepts, mainly concepts of sovereignty, citizenship, also the freedom of movement and residence, freedom of business and consume, which are fundamentals of neoliberal economic-political system. Retreat expects elaborated and organized migration to beforehand chosen and arranged areas. Opposite to retreat is mass escape chaos that reduces human relations to fight for survival. As J. Lovelock proposed in his sustainable retreat concept, relocating people from areas affected by climate changes to climate oases would mean that rich northern countries give up their current, in fact, isolationistic politics that refuses climate migrants. Therefore the sustainable retreat concept requires much greater competence and mainly willingness to cooperate not only on national, but also on international and global level more than humanity is able to do it currently.

Current globalization has its predecessor in the global market of the 19th century. In that time, the main sign of globalization was de socialization of the economy. That globalization ended during World War I as a result of applying the liberal ideology of de socialization to an economy. An attempt to rebuild the global market after World War I led to the global economic crisis (1929 1932), which in Germany allowed Nazis to take over and finally led to World War (...) II. In result of this development after the war, the idea of a welfare state arose in Western Europe. However, the problems brought about by realization of this idea led to further globalization and consequently to the rebuilding of the global market. It is clear that current globalization rebuilds also the process of de socialization of the economy. It seems that this causes the repetition of radicalizations from left to right extremist movements. The current global economic crisis or the combination of energy and environmental crises could end the current globalization trend in the same way as it was brought to an end in the first half of the 20th century.

The article presents the concept of ecological civilization and examines some of its aspects and its philosophical background. It points to the problem of under-standing the concepts of culture and civilization, also in relation to the under-standing of civilization as a further stage in the development of society. The ecological civilization should overcome the contemporary industrial civilization and its devastating effects on society and the environment. In examining the philosophical background of the concept, it focuses on Daoism and its relevance (...) to contemporary, especially Chinese environmentalism. Finally, it deals with the differences between the Chinese and Western versions of the concept of ecological civilization, which identifies in a different understanding of the possibilities of ecological democracy and authoritarianism as tools for achieving an environ-mentally sustainable society.

This paper analyzes the current crisis of the global industrial civilization as a coincidence of external and internal reasons, mainly as a coincidence of economic and environmental crises tendencies. The analysis is based on Habermas´ distinction between four types of social formation, and according to their internal organizational principles and an extent of their social and system integration, also types of crises that can occur in the given type of the social formation. The paper shows that the common reason of (...) economic and environmental crises which are a part of system crisis of industrial civilization is an imperative of growth. This imperative, as Habermas points out, is the immanent principle of institutions and systems of capitalism. Economic and demographic growth of industrial civilization based on capitalism principles has reached its limits. However, all types of social formation, institutions and civilizations are also determined by the imperative of sustainability. The current crisis is then characterized as a display of antagonism between the imperative of growth and imperative of sustainability. This antagonism creates a new category of transformation for sustainable societies or revolution conflicts in states that break environmental and economic limits of growth. These conflicts result from food and water shortages and could bring a growing instability into the world or lead into the collapse of the industrial civilization. (shrink)

The more the number of people who live on Earth grows, the more significant are the cuts individuals must accept in realization of their own freedom, so as not to limit the freedom of others. With the growing population on the finite planet the real space for freedom of each individual decreases. Moreover, the growth of complexity of the global industrial civilization increases the degree of interdependence on one hand, on the other the degree of mutual trust decreases as a (...) result of the imperative of growth and profit, and without it no human society can function in the long term. Access to sources necessary for the realization of fundamental freedoms is unequal, and, in fact, it thus limits its accessibility for the majority of human population. Philosophical reflection then should cope with question, whether the range of guaranteed freedoms can be broadened or at least sustained when the space for its realization with the growing human population struggling for increasingly limited resources narrows.

Critical examination of possible socio-political Anthropocene consequences leads to the conclusion that the sustainable development concept is not an adequate answer for current threats and risks. An effort to implement the sustainable development concept can even make climate changes and other forms of nature devastation worse, as it turns out on ongoing greenhouse gas concentrations growth in the atmosphere, despite obligations that result to all states of the world from Paris agreement. The climate change rate and range of plant and (...) animal species extinction confirms J. Lovelock´s thesis that humanity does not have enough time and, most likely, enough sources to implement the sustainable development concept and, as B. Latour points out, we do not have a big enough planet. Therefore, it is necessary to think about a retreat – to areas that are likely to stay livable even after the sea level rise and desertification; it is necessary to think about how to move millions of people from areas flooded by sea or parched by desert; to think about a change of our current way of life, of production of food and energy so that not only humankind as animal species would continue, but also our civilization and its technological and organizational knowledge. Even basic theses based on this concept indicate a need to reassess most political concepts, mainly the concepts of sovereignty, citizenship, but also those of freedom of movement and residence, freedom of business and consume, which work as fundamentals of the neoliberal economic-political system. Retreat expects complex and organized migration to beforehand chosen and arranged areas. Opposite to retreat is mass escape chaos that reduces human relations to fight for survival. As J. Lovelock proposed in his sustainable retreat concept, relocating people from areas affected by climate changes to climate oases would mean that rich northern countries give up their current, in fact, isolationistic politics of refusing climate migrants. Therefore, the concept of sustainable retreat requires much greater competence and especially willingness to cooperate not only nationally, but also internationally and globally, in addition to what humanity is capable of doing today.

This study focuses on the foundations of Slovak critical environmentalism laid by work of Juraj Kučírek, who is also the author of the first ever monograph focused on the philosophical reflection of the causes and possible consequences of the global environmental crisis in Slovakia. Kučírek pointed out the need to combine reflection on subsequent solution of the global environmental crisis with the problems of social inequality and oppression. This unconventional approach in the context of the Slovak public and academic discourse (...) of the 1990s he termed as environmental anthropocentrism. Thus, he had a critical approach to biocentric concepts, which gained a dominant position in the Slovak environmental discourse. His work was followed by Ivan Dubnička, who extended Kučírek´s position to include cultural, political, and religious aspects of the causes of environmental devastation. His research was focused on the relationships of sociobiological and sociocultural determinants that shape human behaviour as a result of biological and cultural evolution. Based on evolutionism and anthropocentrism, he developed the concept of environmental pragmatism. Concepts of both are characterized by the critique of biocentric egalitarianism principle and the emphasis on democratic and human rights aspects of environmental devastation, as well as social and political causes of these phenomena.

Development plans at different levels – from local to global – aspire to eliminate poverty, famine, to make health care accessible, to create better access to education, to improve transportation, employment, and the quality of life, all within next decades. Yet, these plans collide with the reality of climate change, more precisely the Anthropocene, which already creates high-dimensional conflicts. These will only intensify within decades because climate change and other consequences of the environment global devastation lead to a real decrease (...) of resources. These resources enable not only development but also an elementary reproduction of the essential preconditions of life. The current model of development has substantially contributed to the intensification of unequal accessibility to resources and existing conflicts have thus heightened and new ones have emerged. Water as an essential resource will cause new conflicts. Growing population, expansion of deserts and a sea level rise then increase conflicts for the land. Heat waves occur more often which strengthens conflicts for land suitable for human life, meaning that inhabitable areas are spreading. Therefore there is a need to re-evaluate the character and hierarchy of resources and their accessibility, and also concepts of development. The existing development of humankind has been done at the expense of others in many cases and mainly at the expense of the environment. The current situation raises a question of climate justice from both historical and systematic viewpoints. It opens a need to reformulate the concept of human rights from the perspective of their essential environmental preconditions and to define the status of environmental migrants. (shrink)

This study examines the origins and main aspects of the Chinese concept of ecological civilization. Originally a philosophical concept, it was later developed into a political and constitutional principle and became the basis of several public policies of the Chinese government. The author also draws attention to several contradictions and weaknesses in the concept, which has been seen as a Chinese version of sustainable development and ultimately as a Chinese concept of global civilization.

Understanding of the term of crisis significantly influences the main argumentation line of the philosophical conceptions stimulated by the reflection of the crisis. The deep ecology of A. Naess belongs to these philosophical concepts. The term of crisis in his thinking appears in a form of a threat as well as opportunity, necessity to make important decisions. It also has a meaning of historical and political crisis, i.e. situations in which under the pressure the basic imperatives and organizational principles of (...) the society are reformulated. Such a broad semantic spectre of the crisis concept is connected with the fact that Naess wants to address not only ecologists, environmentalists and philosophers, but also political scientists and social activists by which he greatly contributed to the constitution of environmentalism as a political movement as well as a political ideology. -/- Chápanie pojmu krízy významne ovplyvňuje hlavnú argumentačnú líniu filozo­fických koncepcií, ktorých vznik podnietila reflexia krízy.

The book is an attempt to identify the main principles of a new political philosophy corresponding to the parameters of the Anthropocene, i.e. the geological-climatic epoch of the planetary system in which the negative influence of man on planetary cycles and evolutionary processes exceeds the influence of geological forces. Humanity has become the dominant force affecting all components of the planetary ecosystem (biosphere, hydrosphere, atmosphere, cryosphere, lithosphere) and its activities bring with them problems that affect the social and political spheres. (...) An Introduction to Environmental Political Philosophy illustrates these problems, examines their causes and phenomena, and seeks to understand them in detail. The book does not formulate cheap populist solutions or serve as a political agenda. Rather, it presents philosophical analyses of ecologically, sociologically, politically, and economically contingent phenomena in order to achieve a comprehensive understanding of the socio-political situation of the Anthropocene.

This article outlines the role of globalized mass media in the perception of environmental and social threats and its reciprocal conditionality in the globalized society. It examines the reasons why the global environmental crisis will not lead to a world-wide environmental movement for change of the basic imperatives of the world economicpolitical system. Coherency between globalized mass media and wide-spreading of consumer lifestyle exists despite the fact that it deepens the devastation of environment and social conflicts. Globalized mass media owned (...) by transnational corporations are not only a part of the current global economic-political system, but also the prerequisite of its creation and existence, as well as social contradictions and conflicts.

The political philosophy originates from the reflections of crisis, risks and threats which society faces to. The author understands environmentalism as a tendency of current political philosophy which starts from the reflections of causes and possible effects of global environmental crisis as one of the most serious threats to the existential preconditions of current political system and global civilization at all. Considering the changes in social, technological and environmental starting conditions of the existence of economic-political system – that are consequences (...) of the transition from stable geologic-climate era of Holocene to unstable era of anthropocene – it is necessary to reconsider once more the basic premises, imperatives and conceptual frames of current economic-political system. The outlines of current economic-political system in philosophical frame were laid out by founders of modern political thinking while we can identify some of basic premises of environmentalism and also concepts relevant to the reflection of current threats and risks in some of their works. Author considers the concept of civil and human rights, the concept of natural state and the concept of social contract to be suitable for the reflection of the crisis of current economic-political system regarding environmentalism. Afterwards, the author formulates in what meanings are these concepts actual also for anthropocene. In conclusion, the author´s hypothesis is that the political philosophy of 21st century must reflect the environmental preconditions and limits of existence and forms of economic-political system and, at the same time, it must take into account that any economic and social activities have influence on the quality and sustainability of environment.

The paper describes economic crises as a term with different kinds of meanings, a term which undergoes continuous development. The way of understanding this term is intimately connected with the role of state in the sphere of economy. Before the big economic crises nobody expected the state to interfere with the economy. However, after the crises in 1930's till the end of 1970's it was considered as one of the main tasks of the state. The role of state was to (...) prevent the crises or to reduce its negative consequences. Due to the dominant position of the economic thinking in the present-day world the meanings of the term economic crises influence also the meanings of term crises in other fields. (shrink)

The proof theory of many-valued systems has not been investigated to an extent comparable to the work done on axiomatizatbility of many-valued logics. Proof theory requires appropriate formalisms, such as sequent calculus, natural deduction, and tableaux for classical (and intuitionistic) logic. One particular method for systematically obtaining calculi for all finite-valued logics was invented independently by several researchers, with slight variations in design and presentation. The main aim of this report is to develop the proof theory of finite-valued first order (...) logics in a general way, and to present some of the more important results in this area. In Systems covered are the resolution calculus, sequent calculus, tableaux, and natural deduction. This report is actually a template, from which all results can be specialized to particular logics.

Logic has pride of place in mathematics and its 20th century offshoot, computer science. Modern symbolic logic was developed, in part, as a way to provide a formal framework for mathematics: Frege, Peano, Whitehead and Russell, as well as Hilbert developed systems of logic to formalize mathematics. These systems were meant to serve either as themselves foundational, or at least as formal analogs of mathematical reasoning amenable to mathematical study, e.g., in Hilbert’s consistency program. Similar efforts continue, but have been (...) expanded by the development of sophisticated methods to study the properties of such systems using proof and model theory. In parallel with this evolution of logical formalisms as tools for articulating mathematical theories (broadly speaking), much progress has been made in the quest for a mechanization of logical inference and the investigation of its theoretical limits, culminating recently in the development of new foundational frameworks for mathematics with sophisticated computer-assisted proof systems. In addition, logical formalisms developed by logicians in mathematical and philosophical contexts have proved immensely useful in describing theories and systems of interest to computer scientists, and to some degree, vice versa. Three examples of the influence of logic in computer science are automated reasoning, computer verification, and type systems for programming languages. (shrink)

Methods available for the axiomatization of arbitrary finite-valued logics can be applied to obtain sound and complete intelim rules for all truth-functional connectives of classical logic including the Sheffer stroke and Peirce’s arrow. The restriction to a single conclusion in standard systems of natural deduction requires the introduction of additional rules to make the resulting systems complete; these rules are nevertheless still simple and correspond straightforwardly to the classical absurdity rule. Omitting these rules results in systems for intuitionistic versions of (...) the connectives in question. (shrink)

Drawing on a passage from Ramsey's Truth and Probability, we formulate a simple, plausible constraint on evaluating the accuracy of credences: the Calibration Test. We show that any additive, continuous accuracy measure that passes the Calibration Test will be strictly proper. Strictly proper accuracy measures are known to support the touchstone results of accuracy-first epistemology, for example vindications of probabilism and conditionalization. We show that our use of Calibration is an improvement on previous such appeals by showing how it answers (...) or sidesteps problems that have been raised for previous work in this area. (shrink)

The Intergovernmental Panel on Climate Change has developed a novel framework for assessing and communicating uncertainty in the findings published in their periodic assessment reports. But how should these uncertainty assessments inform decisions? We take a formal decision-making perspective to investigate how scientific input formulated in the IPCC’s novel framework might inform decisions in a principled way through a normative decision model.

Effective altruism sounds so innocuous—who could possibly be opposed to doing good more effectively? Yet it has inspired significant backlash in recent years. This paper addresses some common misconceptions and argues that the core “beneficentric” ideas of effective altruism are both excellent and widely neglected. Reasonable people may disagree on details of implementation, but all should share the basic goals or values underlying effective altruism.

Some of the most important developments of symbolic logic took place in the 1920s. Foremost among them are the distinction between syntax and semantics and the formulation of questions of completeness and decidability of logical systems. David Hilbert and his students played a very important part in these developments. Their contributions can be traced to unpublished lecture notes and other manuscripts by Hilbert and Bernays dating to the period 1917-1923. The aim of this paper is to describe these results, focussing (...) primarily on propositional logic, and to put them in their historical context. It is argued that truth-value semantics, syntactic ("Post-") and semantic completeness, decidability, and other results were first obtained by Hilbert and Bernays in 1918, and that Bernays's role in their discovery and the subsequent development of mathematical logic is much greater than has so far been acknowledged.

Angell's logic of analytic containment AC has been shown to be characterized by a 9-valued matrix NC by Ferguson, and by a 16-valued matrix by Fine. We show that the former is the image of a surjective homomorphism from the latter, i.e., an epimorphic image. The epimorphism was found with the help of MUltlog, which also provides a tableau calculus for NC extended by quantifiers that generalize conjunction and disjunction.

What we value, like, endorse, want, and prefer changes over the course of our lives. Richard Pettigrew presents a theory of rational decision making for agents who recognise that their values will change over time and whose decisions will affect those future times.

There is too much that we do not know about COVID-19. The longer we take to find it out, the more lives will be lost. In this paper, we will defend a principle of risk parity: if it is permissible to expose some members of society (e.g. health workers or the economically vulnerable) to a certain level of ex ante risk in order to minimize overall harm from the virus, then it is permissible to expose fully informed volunteers to a (...) comparable level of risk in the context of promising research into the virus. We apply this principle to three examples of risky research: skipping animal trials for promising treatments, human challenge trials to speed up vaccine development, and low-dose controlled infection or “variolation.” We conclude that if volunteers, fully informed about the risks, are willing to help fight the pandemic by aiding promising research, there are strong moral reasons to gratefully accept their help. To refuse it would implicitly subject others to still graver risks. (shrink)

In Mind and World, John McDowell argues against the view that perceptual representation is non-conceptual. The central worry is that this view cannot offer any reasonable account of how perception bears rationally upon belief. I argue that this worry, though sensible, can be met, if we are clear that perceptual representation is, though non-conceptual, still in some sense 'assertoric': Perception, like belief, represents things as being thus and so.

In The Boundary Stones of Thought, Rumfitt defends classical logic against challenges from intuitionistic mathematics and vagueness, using a semantics of pre-topologies on possibilities, and a topological semantics on predicates, respectively. These semantics are suggestive but the characterizations of negation face difficulties that may undermine their usefulness in Rumfitt’s project.

This paper analyses the phenomenology and epistemology of chatbots such as ChatGPT and Bard. The computational architecture underpinning these chatbots are large language models (LLMs), which are generative AI (Artificial Intelligence) systems trained on a massive dataset of text extracted from the Web. We conceptualise these LLMs as multifunctional computational cognitive artifacts, used for various cognitive tasks such as translating, summarizing, answering questions, information-seeking, and much more. Phenomenologically, LLMs can be experienced as a “quasi-other”; when that happens, users anthropomorphise them. (...) For most users, current LLMs are black boxes, i.e., for the most part, they lack data transparency and algorithmic transparency. They can, however, be phenomenologically and informationally transparent, in which case there is an interactional flow. Anthropomorphising and interactional flow can, in some users, create an attitude of (unwarranted) trust towards the output LLMs generate. We conclude this paper by drawing on the epistemology of trust and testimony to examine the epistemic implications of these dimensions. Whilst LLMs generally generate accurate responses, we observe two epistemic pitfalls. Ideally, users should be able to match the level of trust that they place in LLMs to the degree that LLMs are trustworthy. However, both their data and algorithmic opacity and their phenomenological and informational transparency can make it difficult for users to calibrate their trust correctly. The effects of these limitations are twofold: users may adopt unwarranted attitudes of trust towards the outputs of LLMs (which is particularly problematic when LLMs hallucinate), and the trustworthiness of LLMs may be undermined.

Disagreement is common: even informed, intelligent, and generally reasonable people often come to different conclusions when confronted with what seems to be the same evidence. Can the competing conclusions be reasonable? If not, what can we reasonably think about the situation? This volume examines the epistemology of disagreement. Philosophical questions about disagreement arise in various areas, notably politics, ethics, aesthetics, and the philosophy of religion: but this will be the first book focusing on the general epistemic issues arising from informed (...) disagreement. Ten leading philosophers offer specially written essays which together will offer a starting-point for future work on this topic. (shrink)

Conservative assumptions in medical ethics risk immense harms during a pandemic. Public health institutions and public discourse alike have repeatedly privileged inaction over aggressive medical interventions to address the pandemic, perversely increasing population-wide risks while claiming to be guided by ‘caution’. This puzzling disconnect between rhetoric and reality is suggestive of an underlying philosophical confusion. In this paper, I argue that we have been misled by status quo bias—exaggerating the moral significance of the risks inherent in medical interventions, while systematically (...) neglecting the risks inherent in the status quo prospect of an out-of-control pandemic. By coming to appreciate the possibility and significance of status quo risk, we will be better prepared to respond appropriately when the next pandemic strikes. (shrink)

In this paper, we seek a reliabilist account of justified credence. Reliabilism about justified beliefs comes in two varieties: process reliabilism (Goldman, 1979, 2008) and indicator reliabilism (Alston, 1988, 2005). Existing accounts of reliabilism about justified credence comes in the same two varieties: Jeff Dunn (2015) proposes a version of process reliabilism, while Weng Hong Tang (2016) offers a version of indicator reliabilism. As we will see, both face the same objection. If they are right about what justification is, it (...) is mysterious why we care about justification, for neither of the accounts explains how justification is connected to anything of epistemic value. We will call this the Connection Problem. I begin by describing Dunn’s process reliabilism and Tang’s indicator reliabilism. I argue that, understood correctly, they are, in fact, extensionally equivalent. That is, Dunn and Tang reach the top of the same mountain, albeit by different routes. However, I argue that both face the Connection Problem. In response, I offer my own version of reliabilism, which is both process and indicator, and I argue that it solves that problem. Furthermore, I show that it is also extensionally equivalent to Dunn’s reliabilism and Tang’s. Thus, I reach the top of the same mountain as well. (shrink)

According to certain normative theories in epistemology, rationality requires us to be logically omniscient. Yet this prescription clashes with our ordinary judgments of rationality. How should we resolve this tension? In this paper, I focus particularly on the logical omniscience requirement in Bayesian epistemology. Building on a key insight by Hacking :311–325, 1967), I develop a version of Bayesianism that permits logical ignorance. This includes: an account of the synchronic norms that govern a logically ignorant individual at any given time; (...) an account of how we reduce our logical ignorance by learning logical facts and how we should update our credences in response to such evidence; and an account of when logical ignorance is irrational and when it isn’t. At the end, I explain why the requirement of logical omniscience remains true of ideal agents with no computational, processing, or storage limitations. (shrink)

David Hilbert's finitistic standpoint is a conception of elementary number theory designed to answer the intuitionist doubts regarding the security and certainty of mathematics. Hilbert was unfortunately not exact in delineating what that viewpoint was, and Hilbert himself changed his usage of the term through the 1920s and 30s. The purpose of this paper is to outline what the main problems are in understanding Hilbert and Bernays on this issue, based on some publications by them which have so far received (...) little attention, and on a number of philosophical reconstructions of the viewpoint (in particular, by Hand, Kitcher, and Tait).

Conditionalization is one of the central norms of Bayesian epistemology. But there are a number of competing formulations, and a number of arguments that purport to establish it. In this paper, I explore which formulations of the norm are supported by which arguments. In their standard formulations, each of the arguments I consider here depends on the same assumption, which I call Deterministic Updating. I will investigate whether it is possible to amend these arguments so that they no longer depend (...) on it. As I show, whether this is possible depends on the formulation of the norm under consideration. (shrink)

This paper applies a virtue epistemology approach to using the Internet, as to improve our information-seeking behaviours. Virtue epistemology focusses on the cognitive character of agents and is less concerned with the nature of truth and epistemic justification as compared to traditional analytic epistemology. Due to this focus on cognitive character and agency, it is a fruitful but underexplored approach to using the Internet in an epistemically desirable way. Thus, the central question in this paper is: How to use the (...) Internet in an epistemically virtuous way? Using the work of Jason Baehr, it starts by outlining nine intellectual or epistemic virtues: curiosity, intellectual autonomy, intellectual humility, attentiveness, intellectual carefulness, intellectual thoroughness, open-mindedness, intellectual courage and intellectual tenacity. It then explores how we should deploy these virtues and avoid the corresponding vices when interacting with the Internet, particularly search engines. Whilst an epistemically virtuous use of the Internet will not guarantee that one will acquire true beliefs, understanding or even knowledge, it will strongly improve one’s information-seeking behaviours. The paper ends with arguing that teaching and assessing online intellectual virtues should be part of school and university curricula, perhaps embedded in critical thinking courses, or even better, as individual units.

This Element, written for researchers and students in philosophy and the behavioral sciences, reviews and critically assesses extant work on number concepts in developmental psychology and cognitive science. It has four main aims. First, it characterizes the core commitments of mainstream number cognition research, including the commitment to representationalism, the hypothesis that there exist certain number-specific cognitive systems, and the key milestones in the development of number cognition. Second, it provides a taxonomy of influential views within mainstream number cognition research, (...) along with the central challenges these views face. Third, it identifies and critically assesses a series of core philosophical assumptions often adopted by number cognition researchers. Finally, the Element articulates and defends a novel version of pluralism about number concepts. (shrink)

All humans have an equal basic moral status. They possess the same fundamental rights, and the comparable interests of each person should count the same in calculations that determine social policy. Neither supposed racial differences, nor skin color, sex, sexual orientation, ethnicity, intelligence, nor any other differences among humans negate their fundamental equal worth and dignity. These platitudes are virtually universally affirmed. A white supremacist racist or an admirer of Adolf Hitler who denies them is rightly regarded as beyond the (...) pale of civilized dialogue. However, a very simple line of argument developed by Peter Singer challenges our understanding of these platitudes and forces us to rethink the basis and nature of the moral equality of all humans. What I call the “Singer Problem” arises if one accepts that the morally significant cognitive capacities that are relevant to the determination of the fundamental moral status of a being vary from individual to individual by degree. The problem is to specify a moral principle determining fundamental moral status that assigns a superior status to humans compared to other animals on the basis of the superior cognitive capacities of humans but also assigns all human persons an equal fundamental moral status regardless of their differing cognitive capacities. More broadly posed, the problem is to specify moral principles that yield intuitively satisfactory implications for the treatment of human individuals and other individual animals given that cognitive capacities differ across species and individuals. A search for a resolution of the Singer problem leads to disappointing results. (shrink)

In the 1920s, David Hilbert proposed a research program with the aim of providing mathematics with a secure foundation. This was to be accomplished by first formalizing logic and mathematics in their entirety, and then showing---using only so-called finitistic principles---that these formalizations are free of contradictions. ;In the area of logic, the Hilbert school accomplished major advances both in introducing new systems of logic, and in developing central metalogical notions, such as completeness and decidability. The analysis of unpublished material presented (...) in Chapter 2 shows that a completeness proof for propositional logic was found by Hilbert and his assistant Paul Bernays already in 1917--18, and that Bernays's contribution was much greater than is commonly acknowledged. Aside from logic, the main technical contribution of Hilbert's Program are the development of formal mathematical theories and proof-theoretical investigations thereof, in particular, consistency proofs. In this respect Wilhelm Ackermann's 1924 dissertation is a milestone both in the development of the Program and in proof theory in general. Ackermann gives a consistency proof for a second-order version of primitive recursive arithmetic which, surprisingly, explicitly uses a finitistic version of transfinite induction up to www . He also gave a faulty consistency proof for a system of second-order arithmetic based on Hilbert's &egr;-substitution method. Detailed analyses of both proofs in Chapter 3 shed light on the development of finitism and proof theory in the 1920s as practiced in Hilbert's school. ;In a series of papers, Charles Parsons has attempted to map out a notion of mathematical intuition which he also brings to bear on Hilbert's finitism. According to him, mathematical intuition fails to be able to underwrite the kind of intuitive knowledge Hilbert thought was attainable by the finitist. It is argued in Chapter 4 that the extent of finitistic knowledge which intuition can provide is broader than Parsons supposes. According to another influential analysis of finitism due to W. W. Tait, finitist reasoning coincides with primitive recursive reasoning. The acceptance of non-primitive recursive methods in Ackermann's dissertation presented in Chapter 3, together with additional textual evidence presented in Chapter 4, shows that this identification is untenable as far as Hilbert's conception of finitism is concerned. Tait's conception, however, differs from Hilbert's in important respects, yet it is also open to criticisms leading to the conclusion that finitism encompasses more than just primitive recursive reasoning.

Veritism says that the fundamental source of epistemic value for a doxastic state is the extent to which it represents the world correctly: that is, its fundamental epistemic value is deter...

In this paper I argue that a priori arguments fail to present any real problem for physicalism. They beg the question against physicalism in the sense that the argument will only seem compelling if one is already assuming that qualitative properties are nonphysical. To show this I will present the reverse-zombie and reverse-knowledge arguments. The only evidence against physicalism is a priori arguments, but there are also a priori arguments against dualism of exactly the same variety. Each of these parity (...) arguments has premises that are just as intuitively plausible, and it cannot be the case that both the traditional scenarios and the reverse-scenarios are all ideally conceivable. Given this one set must be merely prima facie conceivable and only empirical methods will tell us which is which. So, by the time a priori methodology will be of any use it will be too late.

In this article, I outline various ways in which artifacts are interwoven with autobiographical memory systems and conceptualize what this implies for the self. I first sketch the narrative approach to the self, arguing that who we are as persons is essentially our (unfolding) life story, which, in turn, determines our present beliefs and desires, but also directs our future goals and actions. I then argue that our autobiographical memory is partly anchored in our embodied interactions with an ecology of (...) artifacts in our environment. Lifelogs, photos, videos, journals, diaries, souvenirs, jewelry, books, works of art, and many other meaningful objects trigger and sometimes constitute emotionally-laden autobiographical memories. Autobiographical memory is thus distributed across embodied agents and various environmental structures. To defend this claim, I draw on and integrate distributed cognition theory and empirical research in human-technology interaction. Based on this, I conclude that the self is neither defined by psychological states realized by the brain nor by biological states realized by the organism, but should be seen as a distributed and relational construct.

The desirability of what actually occurs is often influenced by what could have been. Preferences based on such value dependencies between actual and counterfactual outcomes generate a class of problems for orthodox decision theory, the best-known perhaps being the so-called Allais Paradox. In this paper we solve these problems by extending Richard Jeffrey's decision theory to counterfactual prospects, using a multidimensional possible-world semantics for conditionals, and showing that preferences that are sensitive to counterfactual considerations can still be desirability maximising. (...) We end the paper by investigating the conditions necessary and sufficient for a desirability function to be an expected utility. It turns out that the additional conditions imply highly implausible epistemic principles. (shrink)

This paper argues that a popular account of intentions can be extended to beliefs. Beliefs are stable all-out states that allow for planning and coordination in a way that is tractable for cognitively limited creatures like human beings. Scepticism is expressed that there is really anything like credences as standardly understood.
