This paper introduces the philosophy of Grace Andrus de Laguna in order to renew interest in it. I show that, in the 1910s and 1920s, she develops ideas and arguments that are also found playing key roles in the development of analytic philosophy decades later. Further, I describe her sympathetic, but acute, criticism of pragmatism and Heideggerian ontology, and situate her work in the tradition of American, speculative philosophy. Before 1920, we will see, de Laguna appeals to multiple realizability to (...) undermine reductionism in science, to support perspectival, scientific realism and, with help from a private language argument, to favour the view that mental states are classified by behavioural, teleological roles over what came to be called ‘type physicalism’. Her view of speech, mostly developed in the 1920s, tells us that its primary role is coordinating group behaviour rather than expressing thoughts. Belief is understood in terms of its causal role, including its causal relations to other kinds of mental states, when coordinating group behaviour. Thought is similarly understood. In developing her theory of mind, de Laguna rejects the pragmatist claims that belief can be reduced to dispositions to behaviour and that thought’s function is to address specific, rather than general, problems. She also favours meaning holism and rejects the analytic–synthetic distinction. In later work, de Laguna argues that individuals’ activity of self-maintenance brings universals, conceived of as irreducible potentialities, into being and makes them increasingly determinate. Further, she identifies the existence of all individuals with forms of self-maintenance and takes the existence of people to include maintenance of the cultural world. Such a unified treatment of existence, she holds, permits making its evolution intelligible. Heidegger’s view of being is rejected for not permitting this. All de Laguna’s work, we will see, fits a vision of philosophy as the systematic, imaginative and naturalistic examination of being as well as a source of criticism of science. (shrink)

This chapter considers potential applications of grounding to the formulation of physicalism. I begin with an overview of competing conceptions of the physical and of physicalism. I then consider whether grounding physicalism overcomes well-known and seemingly fatal problems with supervenience physicalism. I conclude that while grounding physicalism improves upon supervenience physicalism in certain respects, it arguably falls victim to some of the same difficulties.

Ernst Cassirer’s focus on the expressive function of language should be read, not in the context of Carnap’s debate with Heidegger, but in the context of the earlier work of Chajim (Heymann) Steinthal. Steinthal distinguishes the expressive form of language, when language is studied as a natural phenomenon, from language as a logical, inferential system. Steinthal argues that language always can be expressed in terms of logical inference. Thus, he would disagree with Heidegger, just as Carnap does. But, Steinthal insists, (...) that is not to say that language, as a natural phenomenon, is exhausted by logic or by the place of terms or relations in inferential structures. Steinthal’s “form” of linguistic “expression” is an early version of Cassirer’s “expressive function” for language. The expressive function, then, should not be seen to place a barrier between Carnap and Cassirer. Rather, Steinthal and Cassirer deal with a question that, as far as I know, Carnap does not address directly: how should philosophers analyze human language as a natural phenomenon, as a part of our expression as animals? And how does that expression determine the semantic categories, kind terms, and other structures that develop within, and characterize, human language itself? (shrink)

Positivism has been used to establish a standard that Information Systems (IS) research must meet to be scientific. According to such positivistic beliefs in IS, scientific research should: 1) be generalizable, 2) focus on stable independent variables, 3) have certain ontological assumptions, and 4) use statistical or quantitative methods rather than qualitative methods. We argue that logical positivist philosophers required none of these. On the contrary, logical positivist philosophers regarded philosophizing in general and ontological considerations in particular as nonsense. Moreover, (...) the positivists’ preferred empirical research method was not a survey, but rather a qualitative observation recorded by field notes. In addition, positivist philosophers required neither statistical nor nonstatistical generalizability. At least some positivist philosophers also acknowledged the study of singular cases as being scientific. Many research orientations (e.g., single-setting research, examination of change, qualitative research) that are deemed “unscientific” by positivism in IS seem to be “scientific” (in principle) according to logical positivism. In turn, generally speaking, what has been justified as scientific by positivism in IS (e.g., requirements of statistical or nonstatistical generalizability, surveys, independent variables, ontological views) were either not required by logical positivists or were regarded as nonsensical by logical positivists. Furthermore, given that positivism is sometimes associated (or confused) with logical empiricism in IS, we also briefly discuss logical empiricism. Finally, realizing that certain influential, taken-forgranted assumptions that underlie IS research are unwarranted could have ground-breaking implications for future IS research. (shrink)

Chalmers introduced the hard problem of consciousness as a profound gap between experience and physical concepts. Philosophical theories were based on different interpretations concerning the qualia/concept gap, such as interactive dualism (Descartes), as well as mono aspect or dual aspect monism. From a bio-psychological perspective, the gap can be explained by the different activity of two mental functions realizing a mental representation of extra-mental reality. The function of elementary sensation requires active sense organs, which create an uninterrupted physical chain from (...) extra-mental reality to the brain and reflect the present. The function of categorizing reflection no longer needs sense organs, so that the physical chain to extra-mental reality is interrupted and now reflects the past. Whereas elementary sensation is an open system, categorizing reflection remains a closed system, separated from extra-mental reality. This creates the potentiality/reality gap, since prediction from the closed to the open system remains always uncertain. Elementary sensation is associated to specific qualia for each sense organ. Chalmers also attributed qualia to thoughts, with more neutral thought qualia. Thus at the qualia level, there is also an important gap, but now between specific sense qualia and neutral thought qualia. Since all physical concepts are simultaneously linked to neutral thought qualia, the hard problem might be explained by a qualia/qualia gap instead of a qualia/concept gap. The mental function of categorizing reflection induces the change from sense qualia to thought qualia by a categorization process. The specific sense qualia mosaic of an apple is reduced to physical concepts with neutral qualia by progressive categorization first to fruit, then to food, to chemicals and finally to calories. This might explain the gap felt in the hard problem, since specific sense qualia are completely different from neutral thought qualia, so that the hard problem could already be encountered at the qualia level. Since the gap of the hard problem is due to the interaction of different mental functions, it is compatible with a philosophical monism. (shrink)

It seems certain to me that I will die and stay dead. By “I”, I mean me, Greg Nixon, this person, this self-identity. I am so intertwined with the chiasmus of lives, bodies, ecosystems, symbolic intersubjectivity, and life on this particular planet that I cannot imagine this identity continuing alone without them. However, one may survive one’s life by believing in universal awareness, perfection, and the peace that passes all understanding. Perhaps, we bring this back with us to the Source (...) from which we began, changing it, enriching it. Once we have lived – if we don’t choose the eternal silence of oblivion by life denial, vanity, indifference, or simple weariness – the Source learns and we awaken within it. Awareness, consciousness, is universal – it comes with the territory – so maybe you will be one of the few prepared to become unexpectedly enlightened after the loss of body and self. You may discover your own apotheosis – something you always were, but after a lifetime of primate experience, now much more. Since you are of the Source and since you have changed from life experience and yet retained the dream of ultimate awakening, plus you have brought those chaotic emotions and memories back to the Source with you (though no longer yours), your life & memories will have mattered. Those who awaken beyond the death of self will have changed Reality. (shrink)

What happens to the inner light of consciousness with the death of the individual body and brain? Reductive materialism assumes it simply fades to black. Others think of consciousness as indicating a continuation of self, a transformation, an awakening or even alternatives based on the quality of life experience.

In the spring of 1937, the University of Chicago Press mailed hundreds of subscription forms for its latest enterprise – a projected series of twenty short monographs by various philosophers and scientists. Together the monographs were to form the first section of the International Encyclopedia of Unified Science. Included in each mailing was an introductory prospectus which began:Recent years have witnessed a striking growth of interest in the scientific enterprise as a whole and especially in the unity of science. The (...) concern throughout the world for the logic of science, the history of science, and the sociology of science reveals a comprehensive international movement interested in considering science as a whole in terms of the scientific temper itself. A science of science is appearing. The extreme specialization within science demands as its corrective an interest in the scientific edifice in its entirety. This is especially necessary if science is to satisfy its inherent urge for the systematization of its results and methods and if science is to perform adequately its educational role in the modern world. Science is gradually rousing itself for the performance of its total task. (shrink)

The distinction between the contexts of discovery and justification, this distinction dear to the projects of logical empiricism, was, as is well known, introduced in precisely those terms by Hans Reichenbach in his Experience and Prediction (Reichenbach 1938). Thus, while the idea behind the distinction has a long history before Reichenbach, this text from 1938 plays a salient role in how the distinction became canonical in the work of philosophers of science in the mid twentieth century. The new contextualist history (...) of philosophy that has arisen in recent years invites us into an investigation of the nuances of philosophical distinctions and their roles in shaping the development of disciplines. Logical empiricism played a key role in the historical development of philosophy of science and this contextualist history has revealed a much richer set of projects in logical empiricism than the potted histories had allowed. Many stories have been told about the contexts of justification and discovery; few of those stories have paid more than passing attention to the larger projects in epistemology and meta-epistemology that Reichenbach was pursuing when he drew the distinction. This brief essay will seek partially to rectify that lack in, I hope, a somewhat surprising way. I shall stress the connection between this canonical distinction and some other epistemological and social terms that loom large in Reichenbach’s text, arguing that the social relevance of scientific philosophy for Reichenbach cannot be set aside in understanding his use of the DJ distinction. My point is, therefore, historical and reflexive. If we attend to the larger significance of the project in scientific philosophy that Reichenbach was advancing, we can see more clearly why the DJ distinction was introduced and rethink the significance of questioning the distinction.

Of S. S. Stevens's well-known classification of nominal, ordinal, interval and ratio ‘scales of measurement’, perhaps its least-known aspect is its most distinctive, namely the distinction between interval and ratio scales. This article investigates the circumstances of the typology's origins among the experimental psychologists at Harvard in the 1930s and the unique fusion of personal, technical and intellectual forces this setting represented. It shows how it came to be that an influential psychologist reconceptualized measurement from first principles in such a (...) way as to both preserve the distinction between psychology and physics in this regard and yet implicitly classify his own work as the latter. The article concludes with the general suggestion that, if it is necessary to measure something, it might as well be something tangible enough to be measured usefully. (shrink)

Although now largely forgotten, the international language movement was, from the 1880s to the end of the Second World War, a matter of widespread public interest, as well as a concern of numerous scientists and scholars. The primary goal was to establish a language for international communication, but in the early twentieth century an increasing accent was placed on philosophical considerations: wanted was a language better suited to the needs of modern science and rational thought. In this paper, we examine (...) the example of the English scholar C.K. Ogden's international language Basic English and his efforts to win the Vienna Circle philosophers Otto Neurath and Rudolf Carnap over to the project. Basic is shown to be an implementation of key ideas in Ogden's philosophy of language, ideas shared to a large extent with Neurath and Carnap. This we see through an examination of their unpublished correspondence, as well as through the collaboration that emerged between Ogden and Neurath, in which Neurath's Isotype, a system for graphically representing statistical data, became closely aligned with Basic. Through the ideas and endeavours we investigate here, we gain a new perspective on this crucial period in the history of analytic philosophy. (shrink)

The identity theory’s rise to prominence in analytic philosophy of mind during the late 1950s and early 1960s is widely seen as a watershed in the development of physicalism, in the sense that whereas logical behaviourism proposed analytic and a priori ascertainable identities between the meanings of mental and physical-behavioural concepts, the identity theory proposed synthetic and a posteriori knowable identities between mental and physical properties. While this watershed does exist, the standard account of it is misleading, as it is (...) founded in erroneous intensional misreadings of the logical positivists’—especially Carnap’s—extensional notions of translation and meaning, as well as misinterpretations of the positivists’ shift from the strong thesis of translation-physicalism to the weaker and more liberal notion of reduction-physicalism that occurred in the Unity of Science programme. After setting the historical record straight, the essay traces the first truly modern identity theory to Schlick’s pre-positivist views circa 1920 and goes on to explore its further development in Feigl, arguing that the fundamental difference between the Schlick-Feigl identity theory and the more familiar and influential Place-Smart-Armstrong identity theory has resurfaced in the deep and seemingly unbridgeable gulf in contemporary philosophy of consciousness between inflationary mentalism and deflationary physicalism.

Although culturally prominent modernist influences account for much of Skinner's early behaviorism, the subsequent changes in his views are appropriately considered as postmodern and are indebted to other sources. These changes are strikingly apparent in his 1945 publication. "The Operational Analysis of Psychological Terms." In that publication. Skinner introduced a probabilistic three-term contingency for verbal behavior with an expanded contextualism and an increased emphasis on consequence with a clear alignment to pragmatism. Instead of reaffirming the mechanistic and necessitarian values of (...) modernism that he had previously embraced, Skinner was aligning himself with the postmodern values of pragmatism and selectionism.

Historically, the Vienna Circle and the Dessau Bauhaus were related, with members of each group familiar with the ideas of the other. Peter Galison argues that their projects are related as well, through shared political views and methodological approach. The two main figures that connect the Vienna Circle to the Bauhaus—and the figures upon which Galison focuses—are Rudolf Carnap and Otto Neurath. Yet the connections that Galison develops do not properly capture the common themes between the Bauhaus and Neurath’s philosophical (...) projects. We demonstrate this by considering Neurath’s philosophical commitments. We suggest different connections between Neurath’s projects and the Bauhaus, connections that are both substantive and philosophically interesting. (shrink)

Logical positivism is widely associated with an illiberal technocratic view of politics. This view is a caricature. Some members of the left Vienna circle were explicit in their criticism of this conception of politics. In particular, Neurath's work attempted to link the internal epistemological pluralism and tolerance of logical empiricism with political pluralism and the rejection of a technocratic politics. This paper examines the role that unified science played in Neurath's defence of political and social pluralism. Neurath's project of unified (...) science addressed problems that lie at the centre of recent debates around liberalism concerning the possibility of social co-operation in conditions of pluralism. His response is distinctive in calling upon an empiricist tradition that differs from Kantian proceduralist approaches that have predominated in recent liberalism. While Neurath's position has problems, it deserves reconsideration, especially in so far as it questions the Kantian assumption that a thin language of abstract rights provides the best basis for the cosmopolital lingua franca required by conditions of social pluralism. An investigation of the role that unified science plays in Neurath's politics also gives reasons for revising common misconceptions about the nature of the unity of science programme itself.

John Dewey’s theory of truth is widely viewed as proposing to substitute “warranted assertibility” for “truth,” a proposal that has faced serious objections since the late 1930s. By examining Dewey’s theory in its historical context – and, in particular, by drawing parallels with Otto Neurath’s concurrent attempts to develop a non-correspondence, non-formal theory of truth – I aim to shed light on Dewey’s underlying objectives. Dewey and Neurath were well-known to each other and, as their writing and correspondence make clear, (...) they took similar paths over the mid-century philosophical terrain. I conclude that Dewey’s account of truth is more principled, and more relevant to historical debates, than it first appears. (shrink)

There are four aspects of Augustine’s thought in the Confessiones that have been challenged and redefined in this dissertation: the full contextual matrix as to place, setting, and motivation for writing in Carthage North Africa 397C.E.; the genre and structural framework utilized by Augustine in framing this treatise using Plato’s Allegory of the Cave in Book VII of the Republic; “Confession” redefined as confession of sin, confession of faith and confession of truth; and the meaning or purpose for writing in (...) regards to his scriptural philosophy of consciousness and to the redefining of Socratic ratiocination based on humanistic pagan philosophy to that of theo-ratiocination which Augustine found in Scripture. By theo-ratiocination I mean a necessary Divine illumined consciousness and reasoning as opposed to a “theosophy” which is usually defined as an ecstatic experiencial or subjective Plotininan ecstasy or union with the Divine experience. My term will redefine a rationality that is universal to all created conscious life. By Synchronic – Synthetic - Triunism I challenged both materialist/physicalist (monism) Carnap, Ryle, Quine on mind; and, (dualism) Kantian ideas of a priori (pure reasoning) and a posteriori (empirical reasoning) dichotomy and a divided consciousness. It was shown that Augustine argued for a synchronous (a synchroni) synthetic triunism of consciousness of thought- as opposed to a linear dualism body stimulating mentalistic mind concept. Instead, Past(Memory), Present(Senses), Future(Imagination) synchronically exist in every cognate moment namely, what I will call, Biological(Perception/Body), Mentalistic (Apperception, Mind), and External Illuminative/Inspiration/Concentration (Mentalistic Directive Outside a Controlled Will - Interpretation).

_ Source: _Page Count 19 It is argued in this paper that physicalism is best understood as a research programme, rather than a thesis or an attitude, as some philosophers argue. Given that research programmes connect past, present and future philosophical or scientific activities, physicalists need not decide between current and future physical theories, as it has been required by Hempel’s Dilemma. The author contrasts this proposal with other solutions to Hempel’s Dilemma proposed by currentists, futurists, and those philosophers who (...) claim that physicalism should best be understood as an attitude, arguing that understanding physicalism as a research programme avoids problems that are present in the alternative views, and that it matches well with the standard classifications in the history of philosophy.

I examine the thesis that Otto Neurath anticipated the programme of naturalised epistemology already at the time of the Vienna Circle and consider the relation between Neurath's proposals and those of two contemporary theorists whose research programmes he would thus have broadly anticipated.

The connection between Neurath's programme and the programmes of his two successors considered here, however, is found to be highly indirect in one case and nonexistent in the (...) other — despite their undeniable overlap.

The "standard account" of Wittgenstein’s relations with the Vienna Circle is that the early Wittgenstein was a principal source and inspiration for the Circle’s positivistic and scientific philosophy, while the later Wittgenstein was deeply opposed to the logical empiricist project of articulating a "scientific conception of the world." However, this telegraphic summary is at best only half-true and at worst deeply misleading. For it prevents us appreciating the fluidity and protean character of their philosophical dialogue. In retrospectively attributing clear-cut positions (...) to Wittgenstein and his interlocutors, it is very easy to read back our current understanding of familiar distinctions into a time when those terms were used in a much more open-ended way. The paper aims to to provide a broader perspective on this debate, starting from the protagonists’ understanding of their respective positions. Too often, the programmatic statements about the nature of their work that are repeated in manifestoes, introductions, and elementary textbooks have occupied center stage in the subsequent secondary literature. Consequently, I focus on a detailed examination of a turning point in their relationship. That turning point is Wittgenstein's charge, in the summer of 1932, that a recently published paper of Carnap's, "Physicalistic Language as the Universal Language of Science", made such extensive and unacknowledged use of Wittgenstein's own ideas that Wittgenstein would, as he put it in a letter to Schlick, "soon be in a situation where my own work shall be considered merely as a reheated version or plagiarism of Carnap’s." While the leading parties in this dispute shared a basic commitment to the primacy of physicalistic language, and the view that all significant languages are translatable, there was a remarkable lack of mutual understanding between them, and deep disagreement about the nature of the doctrines they disputed. Three quarters of a century later, we are so much more conscious of the differences that separated them than the points on which they agreed that it takes an effort of historical reconstruction to appreciate why Wittgenstein once feared that his own work would be regarded as a pale shadow of Carnap’s.

En este trabajo se expone el debate entre Neurath y Horkheimer como ejemplo de recuperación de los aspectos políticos del Círculo de Viena, olvidados en la visión tradicional, que ayudarán a tener una mejor comprensión de las diversas posiciones de los miembros del Círculo.

In this work we will summarize the Neurath-Horkheimer debate as an example of the recovery of the Vienna Circle's political aspects that were forgotten in the traditional view, so as to achieve a better understanding of the different positions assumed by the Circle's members. Our intention is to show that much of this debate stems from their political differences and the contenders' diverse conceptions of philosophy, science and reason, but not from the lack of political interests in Neurath and the Vienna Circle.

Analytic ethics in the central period – extending from the beginning of the twentieth century to post-World War II linguistic analysis – is too often construed by historians and philosophers alike in monolithic terms as the emotivism of A. J. Ayer. In contrast, we argue that a multiplicity of ethical doctrines were developed by analytic philosophers at this time of which Ayer's emotivism was just one. Moreover, we maintain that this multiplicity of ethical doctrines was itself the result of a (...) multiplicity of conceptions of analysis and that connecting these two sets of beliefs makes for the best understanding of analytic ethics.

European Journal of Philosophy, EarlyView.

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)

En este artículo se analiza la teoría humoral de la inmunidad propuesta por Paul Ehrlich en 1900, precedida de un conjunto de brillantes investigaciones que al tiempo que parecieran refutar a la teoría anterior –la teoría celular de la inmunidad– fueron el terreno privilegiado en el que se sustentó. Historiaremos esas teorías y experiencias previas, para presentar a continuación el artículo fundacional de la teoría humoral. Nos basaremos en estos hallazgos para caracterizar la estructura de la teoría, utilizando una versión (...) modificada de la concepción estructuralista. Mostraremos cómo teorías previas de otros campos son utilizadas por Ehrlich para proponer su propia teoría, y cómo las experiencias y teorías anteriores del campo inmunológico integran su base empírica. Al hacerlo incursionaremos en el contexto de descubrimiento de la inmunología, proponiendo que consiste en un proceso constructivo. Finalmente, mostraremos la forma que adopta la transición entre la teoría celular y la humoral de la inmunidad. (shrink)

This article presents a reconstruction of the so-called classical, formal or Mendelian genetics, which is intended to be more complete and adequate than existing reconstructions. This reconstruction has been carried out with the instruments, duly modified and extended with respect to the case under consideration, of the structuralist conception of theories. The so-called Mendel’s Laws, as well as linkage genetics and gene mapping are formulated in a precise manner while the global structure of genetics is represented as a theory-net. These (...) results are of methodological, philosophical and didactical relevance. (shrink)
