In order to explain Wittgenstein’s account of the reality of completed infinity in mathematics, a brief overview of Cantor’s initial injection of the idea into set- theory, its trajectory and the philosophic implications he attributed to it will be presented. Subsequently, we will first expound Wittgenstein’s grammatical critique of the use of the term ‘infinity’ in common parlance and its conversion into a notion of an actually existing infinite ‘set’. Secondly, we will delve into Wittgenstein’s technical critique of the concept (...) of ‘denumerability’ as it is presented in set theory as well as his philosophic refutation of Cantor’s Diagonal Argument and the implications of such a refutation onto the problems of the Continuum Hypothesis and Cantor’s Theorem. Throughout, the discussion will be placed within the historical and philosophical framework of the Grundlagenkrise der Mathematik and Hilbert’s problems. (shrink)

ABSTRACT: A traditional objection to inferentialism states that not all inferences can be meaning-constitutive and therefore inferentialism has to comprise an analytic-synthetic distinction. As a response, Peregrin argues that meaning is a matter of inferential rules and only the subset of all the valid inferences for which there is a widely shared corrective behaviour corresponds to rules and so determines meaning. Unfortunately, Peregrin does not discuss what counts as “widely shared”. In the paper, I argue for an empirical plausibility of (...) Peregrin’s proposal. The aim of the paper is to show that we can find examples of meaning-constitutive linguistic action, which sustain Peregrin’s response. The idea is supported by examples of meaning modulation. If Peregrin is right, then we should be able to find specific meaning modulations in which a new meaning is publicly available and modulated in such a way that it has a potential to be widely shared. I believe that binding modulations – a specific type of meaning modulations – satisfy this condition. (shrink)

The paper considers the two main challenges to scientific realism, stemming from confirmation holism and the underdetermination thesis as well as from semantic holism and the incommensurability thesis. Against the first challenge, it is argued that there are other criteria besides agreement with experience that enable a rational evaluation of competing theories. Against the second challenge, it is argued that at most a thesis of local incommensurability can be defended that is compatible with a minimal version of scientific realism, namely (...) conjectural realism. However, in order to establish a fully-fledged scientific realism, one has to refute the local incommensurability thesis as well, showing how a comparison is possible on the level of the proper concepts of the theories in question. The paper examines the prospects for such a comparison, distinguishing three cases. (shrink)

This introductory paper explores a new perspective on argumentation that draws upon the resources of ludology – the critical and academic of study of games qua games. In the Philosophical Investigations, one of the later Wittgenstein’s more mysterious suggestions is that if one understands how games work, then one would be able to understand how natural language works. Similarly, it will be argued that if we look to how games function as games, we will be able to understand how the (...) ‘argument-game’ functions. The epistemic importance of rhetorical argumentation rather than analytic demonstration becomes apparent if we consider ‘argument’ as the communicative interaction in which arguers attempt to improve the cognitive attitudes of a real or potential audience. The activity of arguing is crafted – but not scripted – by the formal aspects of a complex system of interacting elements that give rise to an emergent field of ‘possibility-space’ in which arguments take place. In recognizing how we indirectly craft second-order fields through our first-order design choices, we gain a new perspective and a new set of tools with which to reflect upon the relation between bias, fairness and objectivity in argumentation. Keywords: argumentation theory, language-game, ludology, philosophy, rhetoric. (shrink)

Jaspers’s binary distinction between understanding and explanation has given way first to a proliferation of explanatory levels and now, in John Campbell’s recent work, to a conception of explanation with no distinct levels of explanation and no inbuilt rationality requirement. I argue that there is still a role for understanding in psychiatry and that is to demystify the assumption that the states it concerns are mental. This role can be fulfilled by placing rationality at the heart of understanding without a (...) commitment to the attempt to use rationality to shed light on interpretation and mindedness as though from outside those notions. Delusions still present a significant challenge to philosophical attempts at understanding, but this merely reflects the genuine clinical difficulties such states present. (shrink)

Anthropocentric biases manifest themselves in two different ways in research on animal cognition. Some researchers claim that only humans have the capacity for reasoning, beliefs, and interests; and others attribute mental concepts to nonhuman animals on the basis of behavioral evidence, and they conceive of animal cognition in more or less human terms. Both approaches overlook the fact that language-use deeply informs mental states, such that comparing human mental states to the mental states of nonlinguistic animals is misguided. In order (...) to avoid both pitfalls -- assuming that animals have mental lives just like we do, or assuming that they have no mental lives at all -- I argue for a functional methodological approach. Researchers should study animal cognition by identifying environmental inputs, the functional role of internal states, and behavioral outputs. Doing so will allow for cross-species comparisons in a way that the use of folk psychological terms does not. (shrink)

I defend the claim that some things genuinely matter to human beings. This involves overcoming a series of arguments which suggest that the things that matter to us are arbitrary. These arguments arise out of Nagel’s claim that life is absurd. The thesis also discusses different senses in which life can be said to have meaning. I put religious accounts of the meaning of life to one side. Instead, I focus on outlining how someone can experience their own life as (...) meaningful. My main aim is to show that some things genuinely matter. I argue that some things genuinely matter from the perspective of the individual in virtue of the fact that they can become conscious of their own needs. So, there are facts about human nature that, taken together, show that some things genuinely matter to us. These include our vital needs, our happiness and positive relationships with others. I argue that these things matter to us not simply in virtue of the fact that we happen to think that they matter. Rather, they genuinely matter to us given our nature. (shrink)

The dissertation attempts to answer the question of how to theorize resistance from within the philosophy of social science. To answer this question we must consider more than just the philosophy of social science; we also must look to political and moral philosophy. Resistance to the social norms of one’s community is possible to theorize from within the philosophy of social science once we develop a sufficiently nuanced account of social and moral communities, according to which membership in a community (...) is not defined by sharing judgments, conceptual frameworks, or comprehensive worldviews, but by sharing terms of discourse so that discussion about judgments, conceptual frameworks, and comprehensive worldviews is possible. Understanding the structure of one’s moral community is not the same as to endorsing that structure. This suggests that contestation is already present within communities about what ‘we’ do, up to and including who ‘we’—as a ‘community’—are. Challenging communitarian understandings of what makes a community a community, I argue that communities are best understood as forming around common concerns or perceptions of problems. This contestation plays a major role in determining the identities of communities, and these identities are constantly shifting. (shrink)

In this essay I analyse Wittgenstein’s criticism of several assumptions that are crucial for a large part of cognitive science. These involve the concepts of computational processes in the brain which cause mental states and processes, the algorithmic processing of information in the brain , the brain as a machine, psychophysical parallelism, the thinking machine, as well as the confusion of rule following with behaviour in accordance with the rule. In my opinion, the theorists of cognitive science have not yet (...) seriously considered Wittgenstein’s criticism so they, quite surprisingly, frequently confuse the question “how does it work?” with “what does it do?” But their most “deleterious” mistake is their confusion of the internal computational processes taking place in the brain with socially-based, everyday criteria of recognition and classification of, and knowledge about, the content of mental states.

In the article I discuss the conceptual problem of other minds and different approaches to mental concepts. Firstly, I introduce the conceptual problem and argue that solutions proposed by theory-theory and direct perception approach are inadequate. I claim that mental concepts are neither theoretical terms nor observational terms. Then, I consider third option which states that mental concepts are dispositional terms, i.e. they concern particular patterns (stereotypes) of behavior. Finally, I argue that dispositional approach is to some extent coherent with (...) phenomenological account and that phenomenological concept of embodiment can improve this position. (shrink)

For most archaeologists the meaning of prehistoric art appears to be grounded upon, if not synonymous with, the notion of representation and symbolism. This paper explores the possibility that the depictions we see already 30,000 years before present, for instance, at the caves of Chauvet and Lascaux, before and beyond representing the world, they first bring forth a new process of acting within this world and at the same time of thinking about it. It is argued that the unique ability (...) of those early depictions to disrupt or question the ways the world is experienced under normal conditions makes possible for the visual apparatus to interrogate itself and thus acquire a sense of perceptual awareness not previously available. (shrink)

There seems to be a large gulf between percepts and concepts. In particular, con- cepts seem to be capable of representing things that percepts cannot. We can conceive of things that would be impossible to perceive. (The converse may also seem true, but I will leave that to one side.) In one respect, this is trivially right. We can conceive of things that we cannot encounter, such as unicorns. We cannot literally perceive unicorns, even if we occasionally.

This dissertation aims at a systemic presentation of Neurath’s thinking as a coherent and sui generis whole. In order to satisfy this desideratum, the main idea put forth in this dissertation is that a specific two-way relation holds between two of Neurath’s main philosophical theses: Semantic Coherentism: a sentence is true if, and only if, it belongs to, or can be deduced from, a coherent set of sentences. Sociological Relativism: the value of a social change depends on how it influences (...) the living conditions of a certain group of individuals. The two-way relation is the following: from the reconstructive point of view, Neurathian semantic coherentism entails his sociological relativism; but, from the point of view of the conceptual structure underlying Neurath’s thinking, it is his sociological relativism that entails his semantic coherentism. We thus arrive at a virtuous circle. On the one hand, the appeal to sociological relativism (together with Neurath’s first order sociological commitments) allows us to explain his view of science; on the other hand, only once we have acquired a justification for sociological relativism, via his theory of truth, are we entitled to explain his view of science in this way. The exposition will be guided by the attempt to find an answer to the three following questions: (i) Does Neurath accept the standard threefold definition of knowledge? (ii) What kind of coherentism is endorsed by Neurath? (iii) Is Neurath’s coherentism compatible with empiricism? The answer to the first question will be negative. It will be argued that radical physicalism (i.e. the conjunction between physicalism and epistemic naturalism) entails the rejection of this definition. The answer to the second question will amount to showing that Neurath’s endorsement of semantic coherentism does not entail, as it is sometimes stated, the endorsement of epistemic coherentism. Finally, the third question will be answered negatively by showing that, given Neurath’s theory of protocol sentences, his coherentism and his empiricism are compatible. The exegetical work prompted by the need to answer these questions will provide us with the elements we need in order to substantiate the main idea mentioned above. (shrink)

Translation theory and the philosophy of language have largely gone their separate ways (the former opting to rebrand itself as “translation studies” to emphasize its empirical and anti-theoretical underpinnings). Yet translation theory and the philosophy of language have predominately shared a common assumption that stands in the way of determinate translation. It is that languages, not texts, are the objects of translation and the subjects of semantics. The way to overcome the theoretical problems surrounding the possibility and determinacy of translation (...) is to marry the philosopher of language's concern for determinacy and semantic accuracy in translation with the notion of a “text-type” from the translation theory literature. The resulting text-type conception of semantics (TTS) is a novel alternative to the salient positions of Contextualism and Semantic Minimalism in the contemporary philosophy of language. (shrink)

What is the relationship between pain and the body? I claim that pain is best explained as a type of personal experience and the bodily response during pain is best explained in terms of a type of mechanical neurophysiologic operation. I apply the radical philosophy of identity theory from philosophy of mind to the relationship between the personal experience of pain and specific neurophysiologic mechanism and argue that the relationship between them is best explained as one of type identity. Specifically, (...) pain is a specific type of personal experience identical to a specific type of allostatic stress response comprised of interdependent nervous, endocrine and immune mechanical operations.

Eliminative functionalism is the view that mental attributes, of humans and other machines, consist ultimately in behavioural abilities or dispositions. Hence, ‘Strong AI’: if a machine consistently acts as if it were fully conscious, then conscious it is. From these assumptions, optimistic futurists have derived a variety of remarkable visions of our ‘post-human’ future; from widely-recognised ‘robot rights’ to ‘mind uploading’, immortality, ‘apotheosis’ and beyond. It is argued here, however, that eliminative functionalism is false; for at least on our present (...) knowledge, the subjectively qualitative characteristics of conscious experience are neither deducible from, nor logically required to generate, the performance of any sort of overtly ‘intelligent’, or indeed, characteristically human behaviour. Thus, a machine could easily be designed to report awareness of phenomenal qualities, without necessarily possessing them; and Alan Turing’s ‘Imitation Game’ test for artificial thinking is unable to determine whether or not a machine is sentient. An alternative test is proposed, in which the machine is asked phenomenological questions under conditions designed to detect any form of cheating—whilst also, potentially revealing evidence for the occurrence of genuine qualitative experience.

Over the years, consequentialism has been subjected to numerous serious objections. Its adherents, however, have been remarkably successful in fending them off. As I argue in this paper, the reason why the case against consequentialism has not been more successful lies, at least partly, in the methodological approach that critics have commonly used. Their arguments have usually proceeded in two steps. First, a definition of consequentialism is given. Then, objections are put forward based on that definition. This procedure runs into (...) one of two problems. Substantive criticisms of consequentialism can only be formulated, if the posited definition is sufficiently concrete and narrow. In that case, however, consequentialists can defend themselves using a strategy that I call “interpretive divergence”. They can simply point out that the critic's definition does not accord with their understanding of consequentialism to which criticisms do not apply. If, on the other hand, an all-encompassing definition is used, it is so abstract that it is doubtful whether any substantive criticisms can be formulated. To escape this dilemma, I sketch a methodological approach which drops the assumption that consequentialism should be defined. It assumes, rather, that the term “consequentialism” should be interpreted as a Wittgensteinian family resemblance term. (shrink)

Ethical concerns in e-social science are often raised with respect to privacy, confidentiality, anonymity and the ethical and legal requirements that govern research. In this article, the authors focus on ethical aspects of e-research that are not directly related to ethical regulatory framework or requirements. These frameworks are often couched in terms of benefits or harms that can be incurred by participants in the research. The authors shift the focus to the sources of value in terms of which benefits or (...) harms are understood in real social situations. A central claim of this paper is that the technologies that are used for research are not value neutral, but serve to reinforce some values at the expense of others. The authors discuss databases, modelling and simulation, network analysis as examples of technologies which affect the articulation of values. A view of e-social science as a techno-scientific constellation of researchers, technologies and society, in which values are always already embedded, is put forward as a basis for a view of ethics as reflexive and active engagement, conducted with awareness. Methodological pluralism and proactive openness are also proposed as responses to this view of the ethical dimensions of e-social science. (shrink)

This thesis is a critical and comparative study of four commentators on the later Wittgenstein’s rule following considerations. As such its primary aim is exegetical, and ultimately the thesis seeks to arrive at an enriched understanding of Wittgenstein’s work through the distillation of the four commentators into what, it is hoped, can be said to approach a definitive interpretation, freed of their individual frailties. -/- The thesis commences by explicating the position of Kripke’s Wittgenstein. He draws our attention to the (...) ‘sceptical problem’ of how we are to resolve the apparently paradoxical situation that whilst we seem to use language meaningfully, there is no fact about us that constitutes our meaning one thing as opposed to something else, and consequently the possibility of our actually meaning anything seems to evaporate. Kripke interprets Wittgenstein as accepting the validity of the sceptical problem, but seeking to establish that the force of the problem is radically diminished because the justification which it has shown to be unobtainable is actually unnecessary for rule following to take place. -/- McDowell tries to show that Kripke is mistaken when he views Wittgenstein as endorsing scepticism in this way, because he sees Kripke as failing to appreciate a section of Philosophical Investigations which suggests that one ought to reject the sceptical paradox by correcting the misunderstanding which gives rise to it. McDowell reads Wittgenstein’s claim as being that we mistakenly think we are caught in a dilemma which requires us either to endorse the sceptical paradox or to subscribe to a mythological picture of rule following; whereas, so the thought goes, we must reject the entire dilemma. -/- Although McDowell’s criticism of Kripke is essentially correct, he is motivated to that criticism by an incorrect reading of Wittgenstein. Central to this misinterpretation is his failure to note Wittgenstein’s belief that universal scepticism is nonsensical. Winch does much to flesh out the nature of Wittgenstein’s claim here, although he makes the mistake of attributing to Kripke that position which the latter finds in Philosophical Investigations. Despite inheriting this error from Winch, Diamond nonetheless improves on his attempt to characterize the shortcomings of Kripke’s reading as an interpretation of Wittgenstein, enabling the thesis to reach a conclusion about Wittgenstein’s understanding of rule following.

The “demarcation problem,” the issue of how to separate science from pseu- doscience, has been around since fall 1919—at least according to Karl Pop- per’s (1957) recollection of when he first started thinking about it. In Popper’s mind, the demarcation problem was intimately linked with one of the most vexing issues in philosophy of science, David Hume’s problem of induction (Vickers 2010) and, in particular, Hume’s contention that induction cannot be logically justified by appealing to the fact that “it works,” (...) as that in itself is an inductive argument, thereby potentially plunging the philosopher straight into the abyss of a viciously circular argument.

This thesis is about an investigation of how children with philosophical experience use philosophical discussion as a way of doing research. A Lawrence Stenhouse description of 'research' as "systematic and sustained enquiry made public" served as my starting point for what to count as 'research'. As an interpretive case story of children participating in research as co-researchers, this research is about how I engaged in an after-school Discussion Research Group co-research project with seventeen volunteer students from my Philosophy for Children (...) classes. Our co-research was a methodological experiment in merging genres of research in which we adapted and combined Philosophy for Children and qualitative research techniques in a philosophical exploration of philosophical discussion. Bringing together the children's philosophical expertise and my interest in the use of qualitative research methodologies, I explored how and whether 'to do philosophy' is 'to do research'. (shrink)

Philosophers of mind have distinguished (and sometimes conflated) various qualities. This article tries to sort things out.

In 1982 Saul A. Kripke proposed a reconstruction of the central insights of Ludwig Wittgenstein's remarks on rule-following. The reconstruction prominently featured a sceptical challenge which soon was recognised as a new and very radical form of scepticism. According to the challenge there is no fact of the matter which constitutes meaning. As there is no such fact, the first-person authority people intuitively seem to have concerning what they mean is also baseless. In response to the sceptic, many solutions have (...) been proposed. This thesis is about one family of solutions, according to which facts about meaning are sui generis and can neither be reduced to other facts about the world nor to non-semantic facts about the human mind. The non-reductionist proposals by Colin McGinn and Crispin Wright will be assessed in detail and arguments against both will be introduced. The arguments stem only partially from Kripke himself, some are based on recent literature, others are completely new. The emerging situation will be used as a basis to propose an alternative non-reductionism about meaning-facts. (shrink)

The paper is an attempt to understand Strawson’s notion of the first person in the context of his general theory of a person. More specifically it will relook into the idea that the concept of a person is ‘primitive’, and see how Strawson’s idea of primitiveness of the concept of a person can be extended to his notion of the first person. One way of cashing out the notion of primitiveness in the context of the first person is in terms (...) of the way the pronoun “I” functions in self ascription, like “I am feeling terrible”. As Strawson himself points out, ‘use of “I” is guaranteed against two kinds of failure to which the uses of some other definite referring expressions are sometimes exposed: it is guaranteed against lack of reference, and it is guaranteed against mistaken or incorrect reference.’ Does this way of understanding the primitiveness of first person work? If it does what kind of a notion of first person and authoritative self-knowledge may be derived from it? Another related issue that will be dealt with in the paper is how can one construe the relationship between the first person and the world on the one hand and the first person and ‘the other’ on the other hand within the Strawsonian framework.

Properties and facts play a central role within metaphysics, yet there is no widely accepted account of what constitutes a property or a fact. Traditional conceptions of these metaphysical notions raise serious philosophical puzzles, making the existence of each seem dubious. Drawing on the minimalist theory of truth, I argue in favor of a minimalist conception of properties and facts. A minimalist theory of properties and facts explains these matters in terms of the acceptance of trivial schemas. To make the (...) case that minimalism is a superior approach to properties and facts, I argue against the standard views in the philosophical literature. I argue that the minimalist approach to properties has advantages over realism, nominalism, and the trope theory. I argue that the minimalist approach to facts is superior to the standard treatment of facts on correspondence theories. Metaphysical minimalism, a minimalist metaphysics of properties and facts, is a distinct and superior alternative to the theories of properties and facts currently on offer. (shrink)

Many philosophers worry that cognitive scientists apply the concept REPRESENTATION too liberally. For example, William Ramsey argues that scientists often ascribe natural representations according to the “receptor notion,” a causal account with absurd consequences. I rehabilitate the receptor notion by augmenting it with a background condition: that natural representations are ascribed only to systems construed as organisms. This Organism-Receptor account rationalizes our existing conceptual practice, including the fact that scientists in fact reject Ramsey’s absurd consequences. The Organism-Receptor account raises some (...) worrying questions, but as a more faithful characterization of scientific practice it is a better guide to conceptual reform. (shrink)

The philosophical or theoretical commitments informing psychological research are sometimes characterized, even by theoretical psychologists themselves, as nonempirical, outside the bounds of methodological consideration, and/or nonrational. We argue that this characterization is incoherent. We illustrate our concern by analogy with problematic appeals to Kuhn’s work that have been influential in theoretical psychology. Following the contemporary pragmatist tradition, we argue that our philosophical/theoretical commitments are part of our larger webs of belief, and that for any of these beliefs to have meaning (...) their content must be informed by our practical engagement with the world, i.e., they are based on empirical evidence, broadly construed. It is this empirical basis that allows us to recognize our commitments at all and rationally to assess and criticize them when necessary. We conclude by demonstrating a rational assessment of the philosophical/theoretical commitments underlying a recent study in the social psychology of religion. (shrink)

What is it exactly that we are attributing to a thing when we judge it to be good? According to the orthodox answer, at least in some cases when we judge that something is good we are attributing to it a monadic property. That is, good things are “just plain good.” I reject the orthodox view. In arguing against it, I begin with the idea that a plausible account of goodness must take seriously the intuitive claim that there is something (...) in common between moral and non-moral goodness—something in virtue of which it makes sense to call ‘good’ both the things that are morally good and the things that are non-morally good. However, it is implausible that all judgments about the goodness of things attribute a monadic property to those things, as this does not capture what we mean when we judge something to be non-morally good. Instead, I propose and defend my own relational theory of goodness according to which goodness is a relation that holds between things and ends (or goals). That is, goodness is a relational property such that to be good is to be related in the relevant way to some goal or another. This is true in both the mundane everyday cases and in loftier cases concerned with moral goodness. (shrink)

It is argued that society is a crucial factor in the construction of individual intelligence. In other words that it is important that intelligence is socially situated in an analogous way to the physical situation of robots. Evidence that this may be the case is taken from developmental linguistics, the social intelligence hypothesis, the complexity of society, the need for self-reflection and autism. The consequences for the development of artificial social agents is briefly considered. Finally some challenges for research into (...) socially situated intelligence are highlighted. (shrink)

Knowledge is important for us, human beings, for a variety of reasons, starting with trivial but necessary reasons to live your life. Western man also has a collective project that is constitutive of its culture: science; and the aim of science is to gather knowledge about the world in its broadest meaning: from the origin of a particular disease to the origin of man, life, planet Earth and the universe, from why the orbits move as they do to why a (...) mass of people behaves differently from individuals, from why the sky is blue to why the sea is salty, from why the climate seems to change to why rainbows appear, etc. etc. The quest to understand what knowledge is, is as old as philosophy itself, and the philosophy o.

This paper offers an interpretation of the later Wittgenstein's handling of the idea of an "essence of human language", and examines in particular his treatment of the 'Augustinean' vision of reference as constituting this "essence". A central theme of the interpretation is the perennial philosophical desire to impose upon linguistic meaning conceptual templates drawn from outside the forms of thought about meaning in which we engage when we exercise our capacity to speak and understand a language. The paper closes with (...) a consideration of ways in which Donald Davidson's generally congenial work on interpretation may diverge from Wittgenstein's thinking in this vicinity. (shrink)

In this article I am interpreting Friedrich Nietzsche's piece of writing "How the "True World" finally became a fable - The History of an Error" in the context of 20th-century analytical philosophy of language. In particular, I am going to argue that the main theme in this text - the issue of abolishing "the true world" - can be interpreted as Hilary Putnam's model-theoretic arguments against external realism and Saul Kripke's Wittgensteinian arguments against truth-conditional meaning theories. Interpreting this Nietzsche's text (...) with the help of these arguments gives rise to two options determining Nietzsche's own position. The perspective of Putnam's argument seems to push Nietzsche to the quietist camp - the view that significant metaphysical debate between external realism and its opposite is impossible or inexpressible. On the other hand, the Kripkensteinian perspective gives us reasons to interpret Nietzsche as an adherer of the pragmatic account of semantics, which explains meaning through the use of language.

In this paper, we will discuss what is called the “Manifestation Challenge” to semantic realism, which was originally developed by Michael Dummett and has been further refined by Crispin Wright. According to this challenge, semantic realism has to meet the requirement that knowledge of meaning must be publically manifested in linguistic behaviour. In this regard, we will introduce and evaluate John McDowell’s response to this anti-realistic challenge, which was put forward to show that the challenge cannot undermine realism. According to (...) McDowell, knowledge of undecidable sentences’ truth-conditions can be properly manifested in our ordinary practice of asserting such sentences under certain circumstances, and any further requirement will be redundant. Wright’s further objection to McDowell’s response will be also discussed and it will be argued that this objection fails to raise any serious problem for McDowell’s response and that it is an implausible objection in general.

The main task in this paper is to detail and investigate Carnap’s conception of a “linguistic framework”. On this basis, we will see whether Carnap’s dichotomies, such as the analytic-synthetic distinction, are to be construed as absolute/fundamental dichotomies or merely as relative dichotomies. I argue for a novel interpretation of Carnap’s conception of a LF and, on that basis, will show that, according to Carnap, all the dichotomies to be discussed are relative dichotomies; they depend on conventional decisions concerning the (...) logical syntax of LF. Thus, all of the dichotomies directly hinge on the conception of the LF. The LF’s logical structure, in turn, is an immediate consequence of adopting the linguistic doctrine of logical truths. As we will see, no appeal to any of these distinctions is necessary in establishing a LF and all of its components. I will also draw attention to the differences between what Carnap labels a “way of speaking”, “language”, and “artificial language”. Consequently, I will briefly conclude that none of Quine’s major objections address the main points of Carnap’s theory. (shrink)

In this thesis, I propose and defend a theory according to which committing oneself to knowing the proposition expressed counts as an assertion of that proposition. A consequence of this view is the knowledge account of assertion, according to which one asserts that p correctly only if one knows that p. In support of this approach, I offer a strategy of identifying an assertion’s “normative consequences”, types of act that normally take place as a result of one’s making an assertion (...) incorrectly. I outline two such phenomena: retraction and disavowal of knowledge. In continuation, I put the theory to test and critically examine four sets of objections against it, arguing that it can convincingly defuse them. Finally, I discuss two related issues: I maintain that by performing “aesthetic assertions” one also normally performs a non-assertoric speech act of recommendation, and argue for the possibility of “non-linguistic assertions”, whose content is expressed by gestures in appropriate contexts.

Scientific models are important, if not the sole, units of science. This thesis addresses the following question: in virtue of what do scientific models represent their target systems? In Part i I motivate the question, and lay out some important desiderata that any successful answer must meet. This provides a novel conceptual framework in which to think about the question of scientific representation. I then argue against Callender and Cohen’s attempt to diffuse the question. In Part ii I investigate the (...) ideas that scientific models are ‘similar’, or structurally morphic, to their target systems. I argue that these approaches are misguided, and that at best these relationships concern the accuracy of a pre-existing representational relationship. I also pay particular attention to the sense in which target systems can be appropriately taken to exhibit a ‘structure’, and van Fraassen’s recent argument concerning the pragmatic equivalence between representing phenomena and data. My next target is the idea that models should not be seen as objects in their own right, but rather what look like descriptions of them are actually direct descriptions of target systems, albeit not ones that should be understood literally. I argue that these approaches fail to do justice to the practice of scientific modelling. Finally I turn to the idea that how models represent is grounded, in some sense, in their inferential capacity. I compare this approach to anti-representationalism in the philosophy of language and argue that analogous issues arise in the context of scientific representation. Part iii contains my positive proposal. I provide an account of scientific representation based on Goodman and Elgin’s notion of representation-as. The result is a highly conventional account which is the appropriate level of generality to capture all of its instances, whilst remaining informative about the notion. I illustrate it with reference to the Phillips-Newlyn machine, models of proteins, and the Lotka-Volterra model of predator-prey systems. These examples demonstrate how the account must be understood, and how it sheds light on our understanding of how models are used. I finally demonstrate how the account meets the desiderata laid out at the beginning of the thesis, and outline its implications for further questions from the philosophy of science; not limited to issues surrounding the applicability of mathematics, idealisation, and what it takes for a model to be ‘true’.

It is not Griffith's theory of natural classes what will be discussed, but his ability to offer a solution to the particular issue ofwhich classification system of organisms should be used in Biology.

Este trabajo contiene tres diferentes tipos de objeciones al famoso "argumento del lenguaje privado" de Wittgenstein. Primero ofrezco una reconstrucción posible del argumento. Luego, como primera objeción, e inspirándome en H. N. Castañeda, presento casos donde, contra la opinión de Wittgenstein, el sujeto corrige sus propios errores basándose en distintos criterios subjetivos A continuación, como una segunda objeción, presento situaciones hipotéticas destinadas a mostrar que las experiencias subjetivas, aún si fuesen privadas, podrían en principio ser intersubjetivamente testeadas, si bien en (...) forma indirecta, tal como lo son las entidades inobservables de la ciencia. Finalmente, como tercera objeción, pongo en duda un supuesto básico del cartesianismo sobre el cual descansa el argumento del lenguaje privado. Este supuesto es la conocida tesis de la privacidad de la experiencia subjetiva. Mi argumento contra esta tesis se basa en los casos de bisección cerebral estudiados por T. Nagel, M. Lockwood y otros. This paper contains three different kinds of objections to Wittgenstein's famous "private language argument". First I offer a possible reconstruction of the argument. Then, as a first objection, drawing my ideas from H.N Castañeda, I present cases where, against Wittgenstein's opinion, the subject corrects his own errors based on different subjective criteria. Afterwards, as a second objection, I offer hypothetical examples in order to show that subjective experiences, even is they were private, could in principle be intersubjectively tested, although in a indirect way, as the unobservable entities of science are. Finally, as a third point, I challenge a basic presupposition of Cartesianism on which the private language argument rests. This presupposition is the well known thesis of the essential privacy of subjective experience. My argument against this thesis is based on the split-brain cases, studied by T. Nagel, M. Lockwood and others. (shrink)

One’s life can be meaningful, but not worth living, or worth living, but not meaningful, which demonstrates that an evaluation of whether life is worth living differs from an evaluation of whether one’s life is meaningful. But how do these evaluations differ? As I will argue, an evaluation of whether life is worth living is a more comprehensive evaluation than the evaluation of whether one’s individual life is meaningful. In judging whether one finds life worth living, one takes into account, (...) not only whether one’s life is meaningful, but undesirable aspects of life such as chronic pain and suffering. For example, a person who is suffering greatly, but who has lived a meaningful life, might still conclude that his or her life is not worth living. Although the famed question about the meaning of life has received most of the attention, I argue that the better and more fruitful question is “Is life worth living?” One should want, not just for one’s life to be meaningful, but for it to be worth living.

Enactivism has, perhaps, come to mean different things to different people. The version of enactivism that I am going to build on in this paper is that defended in my book The New Science of the Mind (henceforth NSM). That view is, I think, recognizably enactivist. Others might disagree, and I myself not only characterized it in other terms but was careful to distinguish it from other views that fall under the rubric "enactivist." However, the view I defended is, I (...) think, recognizably enactivist to the extent it regards cognition as, in part, made up of processes whereby an individual manipulates, transforms, and/or exploits structures in its environment. These structures carry information that is relevant to the cognitive task in which the individual is engaged, and the processes are ones that transform this information from information that is merely present to information that is available to the individual. This was a common theme of all my ruminations on this topic, all the way back to The Body in Mind. (shrink)

While in the movies or reading a novel, how can we feel terrified by monsters, ghosts, and fictional serial killers? And how can we feel sad or outraged by depictions of cruelty? After all, we know that the imagined threats that we fear do not exist and, therefore, pose no real threat to us; and we know that the instances of cruelty that bring tears to our eyes have not happened. And yet, the fear, the sadness, or the outrage experienced (...) in our imaginations feels very real. This is the so-called paradox of "fictional emotions." This and related paradoxes have become recalcitrant problems for a purely representational approach to the imagination that tries to accommodate the imagination in a belief-desire psychology, explaining our imaginings as mental states that are similar to beliefs or desires in some ways but not others—as "quasi-beliefs" or "quasi-desires." This representational approach can be seen, for example, in Kendall Walton's influential account of the imagination as "make-believe," or in Shaun Nichols and Stephen Stich's boxological account of the imagination as a "pretend box," which is in close interaction with the suspiciously similar "belief box".
