This is a transcript of a conversation between P F Strawson and Gareth Evans in 1973, filmed for The Open University. Under the title 'Truth', Strawson and Evans discuss the question as to whether the distinction between genuinely fact-stating uses of language and other uses can be grounded on a theory of truth, especially a 'thin' notion of truth in the tradition of F P Ramsey.

New mechanistic philosophy has not examined explanations in ecology although they are based extensively on describing mechanisms responsible for phenomena under scrutiny. This chapter uses the example of research on the shrub Lonicera maackii (Amur honeysuckle) to scrutinize individual-level mechanisms that are generally accepted and used in ecology and confronts them with the minimal account of mechanisms. Individual-level mechanisms are for a phenomenon, are hierarchical, and absent entities play a role in their functioning. They are distinguished by the role played (...) by properties in determining activities and organization. The chapter also considers the experimental methods for discovery of individual-level mechanisms, the possibility of group-level mechanisms in ecology, and suggests further research problems.

Is the Smartphone (SP) an extension of consciousness or just an (other) externalization of the mind and an extension of the social? The concept of externalizing the mind more appropriately describes a series of processes that tend to be considered extensions of the mind. The human mind has evolved concurrently with various externalizations, such as utensils and language, as contributions to the development of the common environment of humanity: culture and civilization. Externalizations indicate the appearance of the human mind while (...) the extensions take into account the possibility of passing to another level (the singularity of consciousness). SP is a handy tool that mediates the personal relationship with the world, benefiting from a level of integration into the global workspace of the mind. Externalization called the SP could be a bridge from the externalization of the mind to its extensions, making the ontological leap from the utensil status to that of "part of the mind". SP is a mediator of an environment: it mediates between the mind and a special social environment called the Internet (mediates access to cognitive support provided by society through the virtual world), which is gradually becoming another reality. SP is part of the extension of human society by introducing tools into the network of personal relationships. Not the mind is expanded, but the social network, increasing the number of entities with which the human can create and maintain relationships. SP may be an extension of the social rather than an extension of the mind because it mediates an increase in the complexity of social relations that can lead to the emergence of "collective minds" (causing a change in the ontological status of society). Changing cognitive demands is a feature of the world's progress. Progress brings along with it cognitive costs of integration, technical solutions like SP, aimed at reducing these costs, generating an evolutionary advantage in the new social context. From an evolutionist perspective, the world means precisely this kind of modification of cognitive demands necessary for survival, SP joining the set of tools that mediate the cognitive progress of the world in which the human is inserted. We propose the use of an evolutionary cognitive economy principle, based on avoiding unnecessary costs, reducing losses and optimizing cognitive gains. (shrink)

Philosophers of science have examined The Theory of Island Biogeography by Robert MacArthur and E. O. Wilson (1967) mainly due to its important contribution to modeling in ecology, but they have not examined it as a representative case of ecological explanation. In this paper, I scrutinize the type of explanation used in this paradigmatic work of ecology. I describe the philosophy of science of MacArthur and Wilson and show that it is mechanistic. Based on this account and in light of (...) contributions to the mechanistic conception of explanation due to Craver (2007), and Bechtel and Richardson (1993), I argue that MacArthur and Wilson use a mechanistic approach to explain the species-area relationship. In light of this examination, I formulate a normative account of mechanistic explanation in ecology. Furthermore, I argue that it offers a basis for methodological unification of ecology and solves a dispute on the nature of ecology. Lastly, I show that proposals for a new paradigm of biogeography appear to maintain the norms of mechanistic explanation implicit in The Theory of Island Biogeography. (shrink)

By using the general investigation framework offered by the cognitive science of religion (CSR), I analyse religion as a necessary condition for the evolutionary path of knowledge. The main argument is the "paradox of the birth of knowledge": in order to get to the meaning of the part, a sense context is needed; but a sense of the whole presupposes the sense (meaning) of the parts. Religion proposes solutions to escape this paradox, based on the imagination of sense (meaning) contexts, (...) respectively closures of these contexts through meta-senses. What is important is the practical effectiveness of solutions proposed by religion, taking into account the costs of faith and the costs of the absence of religious belief. The hypothesis has the following consequences: religion is a necessary condition for the initial evolution of knowledge and the emergence of religion is determined by the evolution of knowledge. The continuation of the solving of paradox is a Bayesian one, using explorations: a sense of the whole allows cognitive arrangements of the parties, which in turn open the possibility of a rearrangement of the whole. The contribution of religion to the emergence of sense (meaning) could be governed by the rule: any map of the world is more useful than no map; any meaning (of life) is better than no meaning. The human mind fills the perceptual and cognitive gaps, some (religious) filling solutions being true vault keys of the entire cognitive construction called the world. Knowledge is conditioned by the existence of an organized context, as the cosmos created by religion by means of explanatory meta-theories supports knowledge by closing the cognitive context and using meaning networks. The proposed analysis is consistent with a redefinition of rationality from the perspective of evolution: the importance and relevance of knowledge is determined by its practical outcome - survival. In the context of useful fictions, it does not matter what God actually does, but what we have done by believing in God. Existence has provided a pragmatic verification of the cognitive solutions that underlie the survival strategies promoted by religions. (shrink)

In 1956, a few writings of Wittgenstein that he didn't publish in his lifetime were revealed to the public. These writings were gathered in the book Remarks on the Foundations of Mathematics (1956). There, we can see that Wittgenstein had some discontentment with the way philosophers, logicians, and mathematicians were thinking about paradoxes, and he even registered a few polemic reasons to not accept Gödel’s incompleteness theorems.

The paper is an examination and critique of the philosophy of science fiction horror of seminal American horror, science fiction and fantasy writer H.P. Lovecraft (1890-1937). Lovecraft never directly offers a philosophy of science fiction horror. However, at different points in his essays and letters, he addresses genres he labels “interplanetary fiction”, “horror”, “supernatural horror”, and “weird fiction”, the last being a broad heading covering both supernatural fiction and science fiction. Taken together, a philosophy of science fiction horror emerges. Central (...) to this philosophy is the juxtaposition of the mysterious, unnatural and alien against a realistic background, in order to produce the emotion that Lovecraft calls “cosmic fear”. This background must not only be scientifically accurate, but must accurately portray human psychology, particularly when humans are faced with the weird and alien. It will be argued that Lovecraft’s prescriptions are overly restrictive and would rule out many legitimate works of science fiction horror art. However, he provides useful insights into the genre.

Huey P. Newton, founder of the Black Panther Party, is perhaps one of the most interesting and intriguing American intellectuals from the last half of the 20th century. Newton’s genius rested in his ability to amalgamate and synthesize others’ thinking, and then reinterpreting and making it relevant to the situation that existed in the United States in his time, particularly for African-Americans in the densely populated urban centers in the North and West. Newton saw himself continuing the Marxist-Leninist tradition and (...) one of the most important aspects of his thought was his reinterpretation of Marxist class structure. This paper presents Newton’s position that it is the urban poor—who Newton identifies with the lumpenproletariat—that act as the revolutionary class that will bring about a change in the socio-economic order. To that end, there is first a discussion of Newton’s view of the lumpenproletariat and how it differs from the traditional Marxist understanding. Then there is an explanation of the role of the vanguard and its relationship to the lumpenproletariat. The paper concludes with a comparison of Frantz Fanon’s and Newton’s understanding of the lumpenproletariat, and responds to the “problem of lumpenization” in the Black Panther Party. (shrink)

Purpose: To develop proposals on the directions of institutional support for the processes of creativity of the Ukrainian economy. Design/methodology/approach: The analysis of trends in the creativity of the Ukrainian economy is carried out and proposals are developed for conceptualizing institutional support for these processes. The authors set out to develop proposals for institutional support for creativity processes and offer recommendations for systematic updating of Ukrainian legislation in the areas of state regulation of high-tech business. The information base was the (...) information materials of the State Statistics Service of Ukraine, Ministry of Economic Development and Trade of Ukraine, the statistical databases of the European Commission, OECD and World Bank for the period 2014–2020. The research methodology is based on scientific tools that include comparative analysis and economic and mathematical modeling. Findings: Building a national program of public investment in creative development will allow us to systematically approach the issue of institutional support for technological breakthroughs. Research limitations/implications: Recommendations on the development and improvement of legislative instruments of deregulatory policy, harmonization with European standards are substantiated. Directions of systematic updating of legislation on guaranteeing foreign investment of creative projects and targeted investment of joint research projects of academic science and creative organizations are proposed. The implementation will allow a systematic approach to the issue of institutional support for the technological breakthrough of Ukraine. Originality/value: There is a need to step up institutional activities in the field of organizing research centers, introduce targeted investment in the academic science and research activity of creative organizations.

Several researchers have recently argued that p values lose their meaning in exploratory analyses due to an unknown inflation of the alpha level (e.g., Nosek & Lakens, 2014; Wagenmakers, 2016). For this argument to be tenable, the familywise error rate must be defined in relation to the number of hypotheses that are tested in the same study or article. Under this conceptualization, the familywise error rate is usually unknowable in exploratory analyses because it is usually unclear how many hypotheses have (...) been tested on a spontaneous basis and then omitted from the final research report. In the present article, I argue that it is inappropriate to conceptualize the familywise error rate in relation to the number of hypotheses that are tested. Instead, it is more appropriate to conceptualize familywise error in relation to the number of different tests that are conducted on the same null hypothesis in the same study. Under this conceptualization, alpha level adjustments in exploratory analyses are (a) less necessary and (b) objectively verifiable. As a result, p values do not lose their meaning in exploratory analyses. (shrink)

This article provides an overview of P.T. Raju’s Neo-Vedantic philosophy of I-am and a relationalist assessment of it.

Some scientific categories seem to correspond to genuine features of the world and are indispensable for successful science in some domain; in short, they are natural kinds. This book gives a general account of what it is to be a natural kind and puts the account to work illuminating numerous specific examples.

Esta coletânea é um tributo a Peter Frederick Strawson pelo centenário de seu nascimento (1919-2019). Diferentemente de outras coletâneas, esta propõe colocar em relevo a interlocução de Strawson com a tradição filosófica. Em outras palavras, por um lado, queremos evidenciar as discussões que Strawson travou com os seus contemporâneos (Austin, Quine, Russell e Wittgenstein), e, por outro, a influência que recebeu e as críticas que dirigiu àqueles que o precederam na história da filosofia (Aristóteles, Descartes, Hume, Kant). Poderíamos ter enriquecido (...) a lista acima com o nome de muitos outros filósofos com os quais Strawson teve contato, mas julgamos que o trabalho ficaria bastante extenso. Por esse motivo, optamos por aqueles nomes mais significativos que figuram na construção da história intelectual de Strawson. O presente volume reúne nove capítulos que levam como título o nome de Strawson e do filósofo com o qual ele dialogou ao longo de suas obras. Essa opção na nomeação dos capítulos por si só já permite colocar em evidência os principais filósofos pelos quais Strawson se interessou e com os quais se confrontou ao longo de seu trabalho filosófico. Com exceção do capítulo sobre Wittgenstein, que é uma versão revisada de um texto publicado anteriormente, todos os outros capítulos são inéditos e foram escritos especialmente para esta coletânea. O volume inclui na abertura a tradução de “Um fragmento de autobiografia intelectual”, de P. F. Strawson. Quando elegemos como título desta obra, Strawson e a tradição filosófica, não estamos insinuando que Strawson é um historiador da filosofia e muito menos que se interesse por historiografia. O título desta obra apenas quer indicar que Strawson, por um lado, transita na história da filosofia com alguma facilidade, além de nutrir um grande apreço por ela e, por outro, que ele discute com os principais nomes da história da filosofia no que concerne aos temas de seu interesse. A sua proposta filosófica é alimentada e irrigada por esse conhecimento, o que lhe dá a possibilidade de assumir na maioria das vezes posições ponderadas e equilibradas acerca de temas complexos por ele tratados. ​ ISBN: 978-85-5696-689-6.

Internalism about moral responsibility is the view that moral responsibility is determined primarily by an agent's mental states; externalism is the view that moral responsibility is determined primarily by an agent's overt behaviour and by circumstances external to the agent. In a series of papers, Michelle Ciurria has argued that most if not all current accounts of moral responsibility, including Strawsonian ones, are internalist. Ciurria defends externalism against these accounts, and she argues that, in contrast to his contemporary followers, P.F. (...) Strawson himself was an externalist. I believe that Ciurria's reading of Strawson is problematic. The aim of this paper is to elucidate Strawson's position with regard to the internalism-externalism issue against the background of Ciurria's reading of him. I conclude that Strawson was neither an internalist nor an externalist about moral responsibility. I draw extensively upon the whole body of Strawson's work, much of which is sadly neglected in discussions of ‘Freedom and Resentment’, although it illuminates many of the issues discussed there.

We call this novel Theory TC*. (shrink)

The Identity principle says that conditionals with the form 'If p, then p' are logical truths. Identity is overwhelmingly plausible, and has rarely been explicitly challenged. But a wide range of conditionals nonetheless invalidate it. I explain the problem, and argue that the culprit is the principle known as Import-Export, which we must thus reject. I then explore how we can reject Import-Export in a way that still makes sense of the intuitions that support it, arguing that the differences between (...) indicative and subjunctive conditionals play a key role in solving this puzzle.

In this paper, I reply to 18 of the essays on panpsychism in this issue. Along the way, I sketch out what a post-Galilean science of consciousness, one in which consciousness is taken to be a fundamental feature of reality, might look like.

The underdetermination of theory by evidence is supposed to be a reason to rethink science. It is not. Many authors claim that underdetermination has momentous consequences for the status of scientific claims, but such claims are hidden in an umbra of obscurity and a penumbra of equivocation. So many various phenomena pass for `underdetermination' that it's tempting to think that it is no unified phenomenon at all, so I begin by providing a framework within which all these worries can be (...) seen as species of one genus: A claim of underdetermination involves (at least implicitly) a set of rival theories, a standard of responsible judgment, and a scope of circumstances in which responsible choice between the rivals is impossible. Within this framework, I show that one variety of underdetermination motivated modern scepticism and thus is a familiar problem at the heart of epistemology. I survey arguments that infer from underdetermination to some reëvaluation of science: top-down arguments infer a priori from the ubiquity of underdetermination to some conclusion about science; bottom-up arguments infer from specific instances of underdetermination, to the claim that underdetermination is widespread, and then to some conclusion about science. The top-down arguments either fail to deliver underdetermination of any great significance or (as with modern scepticism) deliver some well-worn epistemic concern. The bottom-up arguments must rely on cases. I consider several promising cases and find them to either be so specialized that they cannot underwrite conclusions about science in general or not be underdetermined at all. Neither top-down nor bottom-up arguments can motivate any deep reconsideration of science. (shrink)

This paper gives a characterization of distributed cognition (d-cog) and explores ways that the framework might be applied in studies of science. I argue that a system can only be given a d-cog description if it is thought of as performing a task. Turning our attention to science, we can try to give a global d-cog account of science or local d-cog accounts of particular scientific projects. Several accounts of science can be seen as global d-cog accounts: Robert Merton's sociology (...) of scientific norms, Philip Kitcher's 20th-century account of cognitive labor, and Kitcher's 21st-century notion of well-ordered science. Problems that arise for them arise just because of the way that they attribute a function to science. The paper concludes by considering local d-cog accounts. Here, too, the task is the crux of the matter. (shrink)

Standard linguistic analysis of syntax uses the T-model. This model requires the ordering: D-structure > S-structure > LF, where D-structure is the sentences deep structure, S-structure is its surface structure, and LF is its logical form. Between each of these representations there is movement which alters the order of the constituent words; movement is achieved using the principles and parameters of syntactic theory. Psychological analysis of sentence production is usually either serial or connectionist. Psychological serial models do not accommodate the (...) T-model immediately so that here a new model called the P-model is introduced. The P-model is different from previous linguistic and psychological models. Here it is argued that the LF representation should be replaced by a variant of Frege'sA three qualities (sense, reference, and force), called the FregeA representation or F-representation. In the F-representation the order of elements is not necessarily the same as that in LF and it is suggested that the correct ordering is: F-representation > D-structure > S-structure. This ordering appears to lead to a more natural view of sentence production and processing. Within this framework movement originates as the outcome of emphasis applied to the sentence. The requirement that the F-representation precedes the D-structure needs a picture of the particular principles and parameters which pertain to movement of words between representations. In general this would imply that there is a preferred or optimal ordering of the symbolic string in the F-representation. The standard ordering is retained because the general way of producing such an optimal ordering is unclear. In this case it is possible to produce an analysis of movement between LF and D-structure similar to the usual analysis of movement between S-structure and LF. The necessity of analyzing corrupted data suggests that a maximal amount of information about a language's grammar and lexicon is stored. (shrink)

Nell’ambito della filosofia della scienza, il dibattito tra realismo scientifico e antirealismo scientifico ricopre un ruolo di straordinaria importanza. In questo ambito, le posizioni filosofiche elaborate non sono poche. The Instrument of Science di Darrell P.

First, the book does not have an original thesis. The thesisthe author wants to argue is that Smith is different from his current caricature, a legacy of his nineteenth-century image, according to which he would argue that: i) man is a maximizer of utility; ii) man is ordinarily moved by a narrow selfish interest, or at least is indifferent to the interests of others; iii) human beings are social atoms; iv) a perfectly competitive market is morally a free zone (pp. (...) 4-5). The author recognizes that these interpretations "are being questioned by many scholars". contemporary", however, reiterates his conviction that these interpretations are still prevalent, and cites in this regard the abuse of the name of Smith by the Chicago school (p.6). If the author's aim is to challenge a caricature, still common among non-experts but no longer shared by Smith's scholars, one may wonder whether this justifies a new book. Secondly, the author does not demonstrate mastery of the state of the art. She wants to demonstrate the non-existence of Adam Smith Problem, not only without any direct knowledge of German literature but ignoring an important article by Heilbroner from 1981 and a fundamental essay by Dickey from 1986 that explicitly advocate an exhumation of the "Adam Smith problem" in a new form. Thirdly, the author lacks the ability to understand concepts and problems in contextual terms: where she mentions Adam Smith's 'Newtonianism' she does not prove to be familiar with the literature on the subject, citing Lindgren as the only authority and ignoring, among others, Moscovici, Skinner, Hetherington and Freudenthal, but also seems to understand by Newtonianism an equivalent of deterministic and materialistic mechanicism (pp. 48-51). Besides, every time she uses the term utilitarianism he confuses it with the terms hedonism, economicism, selfishness (p. 155). (shrink)

Here, the author tries to build the structure of the Theory of computation based on considering time as a fuzzy concept. In fact, there are reasons to consider time as a fuzzy concept. In this article, the author doesn’t go to this side but note that Brower and Husserl views on the concept of time were similar [8]. Some reasons have been given for it in [3]. Throughout this article, the author presents the Theory of Computation with Fuzzy Time. Given (...) the classic definition of Turing Machine, the concept of Time is modified to Fuzzy time. This new term calls as Theory TC* [2] and this type of computation “Fuzzy time Computation”. We have relatively large number of fundamental unsolved problems in Complexity Theory. In the new theory, some of the major obstacles and unsolved problems have been solved [2]. It should be noted that in this article, the writer considers fuzzy number associated to instants of time as a symmetric one. The point about the symmetry is in the proof of Lemma 3, although it is generalizable. In particular, the new classes of complexity Theory, P*, NP*, BPP* in the TC* analogues to the definitions of P, NP, BPP defines as their natural alternative definition. Here, we will see P*≠ NP*, P*= BPP*. Finally, we have Theorem 4. (shrink)

In this paper, I explore and defend the idea that musical works are historical individuals. Guy Rohrbaugh (2003) proposes this for works of art in general. Julian Dodd (2007) objects that the whole idea is outré metaphysics, that it is too far beyond the pale to be taken seriously. Their disagreement could be seen as a skirmish in the broader war between revisionists and reactionaries, a conflict about which of metaphysics and art should trump the other when there is a (...) conflict. That dispute is a matter of philosophical methodology as much as it is a dispute about art. I argue that the ontology of works as individuals need not be dunked in that morass. My primary strategy is to show, contra Dodd's accusation, that historical individuals are familiar parts of the world. Although the ontological details are open to debate, it is the standard opinion of biologists is that biological species are historical individuals. So there is no conflict here between fidelity to art and respectable metaphysics. What suits species will fit musical work as well. (shrink)

Unlike first-person Moorean sentences, it’s not always awkward to assert, “p, but you don’t know that p.” This can seem puzzling: after all, one can never get one’s audience to know the asserted content by speaking thus. Nevertheless, such assertions can be conversationally useful, for instance, by helping speaker and addressee agree on where to disagree. I will argue that such assertions also make trouble for the growing family of views about the norm of assertion that what licenses proper assertion (...) is not the initiating epistemic position of the speaker but the resulting epistemic position of the audience.

Causal determinism is the view that all events in the universe are predetermined and that the laws of nature causally necessitate these events. In the debates on free will, there are two different positions called incompatibilism and compatibilism. Accordingly, compatibilist accounts claim that free will and causal determinism can be compatible and coexist. On the contrary, incompatibilist accounts defend that compatibilist accounts are problematic and claim that free will cannot exist in a universe where causal determinism holds. The main approach (...) that we will consider in this work will be the incompatibilist approach of the American philosopher Peter van Inwagen, which he defends in free will debates. The arguments put forward by Peter van Inwagen as the basis of incompatibilism can be summarized as the consequence argument and the Mind argument. The consequence argument, hypothetically takes into account a world in which causally deterministic and claiming that free will doesn't exist in such a world. Peter van Inwagen's Mind argument, on the other hand, claims that agent-causation cannot be sufficient for a definite possession of free will because a person who represents oneself as an agent in every event s/he is involved in, cannot be sure whether the consequences of these events are due to chance. In both arguments, Peter van Inwagen refers to philosophical moves that affirm incompatibilism is consistent for free will debate. Therefore in my dissertation, I argue that incompatibilism is actually a sufficient step towards solving the free will and causal determinism dilemma in a theoretical sense. This work also deals with Peter van Inwagen's views on philosophy of action and philosophy of religion in general. Additionally, in order to draw the relational framework between causal determinism and free will, the concepts of 'event', 'causal powers' and 'states of affairs' are used methodologically. Instead of just having an ethical discussion of free will, I took care to stay within the boundaries of the metaphysics of free will. (shrink)

The problem of underdetermination is thought to hold important lessons for philosophy of science. Yet, as Kyle Stanford has recently argued, typical treatments of it offer only restatements of familiar philosophical problems. Following suggestions in Duhem and Sklar, Stanford calls for a New Induction from the history of science. It will provide proof, he thinks, of “the kind of underdetermination that the history of science reveals to be a distinctive and genuine threat to even our best scientific theories” (Stanford 2001, (...) p. S12). This paper examines Stanford’s New Induction and argues that it – like the other forms of underdetermination that he criticizes – merely recapitulates familiar philosophical conundra. (shrink)

The no-miracles argument and the pessimistic induction are arguably the main considerations for and against scientific realism. Recently these arguments have been accused of embodying a familiar, seductive fallacy. In each case, we are tricked by a base rate fallacy, one much-discussed in the psychological literature. In this paper we consider this accusation and use it as an explanation for why the two most prominent `wholesale' arguments in the literature seem irresolvable. Framed probabilistically, we can see very clearly why realists (...) and anti-realists have been talking past one another. We then formulate a dilemma for advocates of either argument, answer potential objections to our criticism, discuss what remains (if anything) of these two major arguments, and then speculate about a future philosophy of science freed from these two arguments. In so doing, we connect the point about base rates to the wholesale/retail distinction; we believe it hints at an answer of how to distinguish profitable from unprofitable realism debates. In short, we offer a probabilistic analysis of the feeling of ennui afflicting contemporary philosophy of science. (shrink)

Thomas Reid is often misread as defending common sense, if at all, only by relying on illicit premises about God or our natural faculties. On these theological or reliabilist misreadings, Reid makes common sense assertions where he cannot give arguments. This paper attempts to untangle Reid's defense of common sense by distinguishing four arguments: (a) the argument from madness, (b) the argument from natural faculties, (c) the argument from impotence, and (d) the argument from practical commitment. Of these, (a) and (...) (c) do rely on problematic premises that are no more secure than claims of common sense itself. Yet (b) and (d) do not. This conclusion can be established directly by considering the arguments informally, but one might still worry that there is an implicit premise in them. In order to address this concern, I reconstruct the arguments in the framework of subjective Bayesianism. The worry becomes this: Do the arguments rely on specific values for the prior probability of some premises? Reid's appeals to our prior cognitive and practical commitments do not. Rather than relying on specific probability assignments, they draw on things that are part of the Bayesian framework itself, such as the nature of observation and the connection between belief and action. Contra the theological or reliabilist readings, the defense of common sense does not require indefensible premises. (shrink)

Most philosophers who study moral responsibility have done so in isolation of the concept of truth. Here, I show that thinking about the nature of truth has profound consequences for discussions of moral responsibility. In particular, by focusing on the very trivial nature of truth—that truth depends on the world and not the other way around—we can see that widely accepted counterexamples to one of the most influential incompatibilist arguments can be shown not only to be false, but also impossible.

P.F. Strawson (1919-2006) was one of the most significant philosophers of the twentieth-century. His career centred around Oxford – first as Tutor and Fellow at University College, then as Waynflete Professor of Metaphysical Philosophy at Magdalen College. His careful, thoughtful, and characteristically elegant written work was influential in moving Oxford philosophy from the anti-metaphysical leanings of A.J. Ayer and J.L. Austin to a renewed and rejuvenated era of traditional philosophy theorising, albeit domesticated in a distinctively Strawsonian fashion. His influence on (...) British philosophy persists through a generation of students who were brought up on his writings. (shrink)

This paper aims to describe the common situations happening in an actual classroom encounter in a Philippine school. It also points out the external expectations of the fresh graduates of education from the training to the actual real teaching. This article used an auto-ethnographical study that highlights the personal experience of the author to highlight the events of most teachers. It was noted that teaching is not only all about the subject matter but more about building a relationship with the (...) students as well. Therefore, building relationships with students requires approaches to be used, reflective stage, observation, and personal encounters as the best way to start learning. Because this is the time when you will start to understand and learn their nature when they are on the verge of a non-threatening atmosphere. (shrink)

This paper argues against the common, often implicit view that theories are some specific kind of thing. Instead, I argue for theory concept pluralism: There are multiple distinct theory concepts which we legitimately use in different domains and for different purposes, and we should not expect this to change. The argument goes by analogy with species concept pluralism, a familiar position in philosophy of biology. I conclude by considering some consequences for philosophy of science if theory concept pluralism is correct.

Typical discussions of virtual reality (VR) fixate on technology for providing sensory stimulation of a certain kind. They thus fail to understand reality as the place wherein we live and work, misunderstanding it instead as merely a sort of presentation. The first half of the paper examines popular conceptions of VR. The most common conception is a shallow one according to which VR is a matter of simulating appearances. Yet there is, even in popular depictions, a second, more subtle conception (...) according to which VR is a matter of facilitating new kinds of interaction. The latter half of the paper turns to questions about the contemporary technology of Internet chatrooms. The fact that chatrooms can be used in certain ways suggests something about the prospects for VR. The penultimate section asks whether chatrooms may legitimately be thought of as places. (In a sense, they may.) The final section asks whether cybersex may legitimately be thought of as sex. (Again, yes.) Chatroom technology thus provides an argument for the second conception of VR over its much ballyhooed rival. (shrink)

Imperatives cannot be true, but they can be obeyed or binding: `Surrender!' is obeyed if you surrender and is binding if you have a reason to surrender. A pure declarative argument — whose premisses and conclusion are declaratives — is valid exactly if, necessarily, its conclusion is true if the conjunction of its premisses is true; similarly, I suggest, a pure imperative argument — whose premisses and conclusion are imperatives — is obedience-valid (alternatively: bindingness-valid) exactly if, necessarily, its conclusion is (...) obeyed (alternatively: binding) if the conjunction of its premisses is. I argue that there are two kinds of bindingness, and that a vacillation between two corresponding variants of bindingness-validity largely explains conflicting intuitions concerning the validity of some pure imperative arguments. I prove that for each of those two variants of bindingness-validity there is an equivalent variant of obedience-validity. Finally, I address alternative accounts of pure imperative inference.

Environmental studies is a highly interdisciplinary field of inquiry, involving philosophers, ecologists, biologists, sociologists, activists, historians and professionals in public and private environmental organizations. It comes with no surprise, then, that the follow-up to Nelson and Callicott’s original anthology The Great Wilderness Debate (1998) features essays from authors in a broad array of disciplines. While there is considerable overlap between the two volumes, this new version offers forty-one essays, five of which are new additions, organized into four sections. What constitutes (...) wilderness? Is wilderness real or social constructed? What kinds of values are served—recreational, aesthetic, scientific, or others—by protecting wild areas? While many commentators trace these questions back to an exchange in the 1990s between two environmental ethicists, J. Baird Callicott and Holmes Rolston III, the debate over the wilderness idea actually has older roots. At least in the U.S. context, it travels back in time to the earliest part of the twentieth-century, when the American public, politicians and ecologists were pressed to justify why wilderness areas should be set aside in a new National Park system. Since then, the fundamental question fuelling the ‘Great Wilderness Debate’ is whether what is being preserved is actually wilderness. Is there such a thing or place as wilderness, that is, a quintessentially non-human or wild setting untainted by human influence? If so, why do we believe such areas deserve protection? (shrink)
