    On Truth: Original Manuscript Materials (1927–1929) From the Ramsey Collection at the University of Pittsburgh.Frank Plumpton Ramsey - 1990 - Dordrecht, Netherland: Springer.
    The present publication forms part of a projected book that F. P. Ramsey drafted but never completed. It survived among his papers and ultimately came into the possession of the University of Pittsburgh in the circumstances detailed in the Editor's Introduction. Our hope in issuing this work at this stage - some sixty years after Ramsey's premature death at the age of 26 - is both to provide yet another token of his amazing philosophical creativity, and also to (...)

  2. General Propositions and Causality.Frank Plumpton Ramsey - 1925 - In The Foundations of Mathematics and Other Logical Essays. London, England: Routledge & Kegan Paul. pp. 237-255.
    This article rebuts Ramsey's earlier theory, in 'Universals of Law and of Fact', of how laws of nature differ from other true generalisations. It argues that our laws are rules we use in judging 'if I meet an F I shall regard it as a G'. This temporal asymmetry is derived from that of cause and effect and used to distinguish what's past as what we can know about without knowing our present intentions.

    The Ramsey theory of the universal homogeneous triangle-free graph.Natasha Dobrinen - 2020 - Journal of Mathematical Logic 20 (2):2050012.
    The universal homogeneous triangle-free graph, constructed by Henson [A family of countable homogeneous graphs, Pacific J. Math.38(1) (1971) 69–83] and denoted H3, is the triangle-free analogue of the Rado graph. While the Ramsey theory of the Rado graph has been completely established, beginning with Erdős–Hajnal–Posá [Strong embeddings of graphs into coloured graphs, in Infinite and Finite Sets. Vol.I, eds. A. Hajnal, R. Rado and V. Sós, Colloquia Mathematica Societatis János Bolyai, Vol. 10 (North-Holland, 1973), pp. 585–595] and culminating (...)

    Continuous Ramsey theory on polish spaces and covering the plane by functions.Stefan Geschke, Martin Goldstern & Menachem Kojman - 2004 - Journal of Mathematical Logic 4 (2):109-145.
    We investigate the Ramsey theory of continuous graph-structures on complete, separable metric spaces and apply the results to the problem of covering a plane by functions. Let the homogeneity number[Formula: see text] of a pair-coloring c:[X]2→2 be the number of c-homogeneous subsets of X needed to cover X. We isolate two continuous pair-colorings on the Cantor space 2ω, c min and c max, which satisfy [Formula: see text] and prove: Theorem. For every Polish space X and every continuous (...)

    Ramsey Theory for Countable Binary Homogeneous Structures.Jean A. Larson - 2005 - Notre Dame Journal of Formal Logic 46 (3):335-352.
    Countable homogeneous relational structures have been studied by many people. One area of focus is the Ramsey theory of such structures. After a review of background material, a partition theorem of Laflamme, Sauer, and Vuksanovic for countable homogeneous binary relational structures is discussed with a focus on the size of the set of unavoidable colors.

  6. Philosophy and Connectionist Theory.William Ramsey, Stephen P. Stich & D. M. Rumelhart (eds.) - 1991 - Hillsdale, N.J.: Lawrence Erlbaum.
    The philosophy of cognitive science has recently become one of the most exciting and fastest growing domains of philosophical inquiry and analysis. Until the early 1980s, nearly all of the models developed treated cognitive processes -- like problem solving, language comprehension, memory, and higher visual processing -- as rule-governed symbol manipulation. However, this situation has changed dramatically over the last half dozen years. In that period there has been an enormous shift of attention toward connectionist models of cognition that are (...)

    Representation Reconsidered.William M. Ramsey - 2007 - Cambridge University Press.
    Cognitive representation is the single most important explanatory notion in the sciences of the mind and has served as the cornerstone for the so-called 'cognitive revolution'. This book critically examines the ways in which philosophers and cognitive scientists appeal to representations in their theories, and argues that there is considerable confusion about the nature of representational states. This has led to an excessive over-application of the notion - especially in many of the fresher theories in computational neuroscience. Representation Reconsidered shows (...)

    The Ramsey theory of Henson graphs.Natasha Dobrinen - 2022 - Journal of Mathematical Logic 23 (1).
    Analogues of Ramsey’s Theorem for infinite structures such as the rationals or the Rado graph have been known for some time. In this context, one looks for optimal bounds, called degrees, for the number of colors in an isomorphic substructure rather than one color, as that is often impossible. Such theorems for Henson graphs however remained elusive, due to lack of techniques for handling forbidden cliques. Building on the author’s recent result for the triangle-free Henson graph, we prove that (...)

  10. Must cognition be representational?William Ramsey - 2017 - Synthese 194 (11):4197-4214.
    In various contexts and for various reasons, writers often define cognitive processes and architectures as those involving representational states and structures. Similarly, cognitive theories are also often delineated as those that invoke representations. In this paper, I present several reasons for rejecting this way of demarcating the cognitive. Some of the reasons against defining cognition in representational terms are that doing so needlessly restricts our theorizing, it undermines the empirical status of the representational theory of mind, and it encourages (...)

    Local Ramsey theory: an abstract approach.Carlos Di Prisco, José G. Mijares & Jesús Nieto - 2017 - Mathematical Logic Quarterly 63 (5):384-396.
    Given a topological Ramsey space math formula, we extend the notion of semiselective coideal to sets math formula and study conditions for math formula that will enable us to make the structure math formula a Ramsey space and also study forcing notions related to math formula which will satisfy abstract versions of interesting properties of the corresponding forcing notions in the realm of Ellentuck's space. This extends results from to the most general context of topological Ramsey spaces. (...)

    This article surveys recent scholarship on Confucian role ethics, examines some of its fundamental commitments, and suggests future directions for scholarship. Role ethics interprets early Confucianism as promoting a relational conception of persons and employs this conception to emphasize how a person's roles and relationships are the source of her ethical obligations and ethical growth. While there is much consensus among role ethic scholars, they disagree over the role of theory in further explicating the view and about the metaphysical (...)

    The Hard Problem of Content is Neither.William Max Ramsey - forthcoming - Review of Philosophy and Psychology:1-22.
    For the past 40 years, philosophers have generally assumed that a key to understanding mental representation is to develop a naturalistic theory of representational content. This has led to an outlook where the importance of content has been heavily inflated, while the significance of the representational vehicles has been somewhat downplayed. However, the success of this enterprise has been thwarted by a number of mysterious and allegedly non-naturalizable, irreducible dimensions of representational content. The challenge of addressing these difficulties has (...)

    Chance in Evolution.Grant Ramsey & Charles H. Pence (eds.) - 2016 - Chicago: University of Chicago.
    Evolutionary biology since Darwin has seen a dramatic entrenchment and elaboration of the role of chance in evolution. It is nearly impossible to discuss contemporary evolutionary theory in any depth at all without making reference to at least some concept of “chance” or “randomness.” Many processes are described as chancy, outcomes are characterized as random, and many evolutionary phenomena are thought to be best described by stochastic or probabilistic models. Chance is taken by various authors to be central to (...)

    Organisms, Traits, and Population Subdivisions: Two Arguments against the Causal Conception of Fitness?Grant Ramsey - 2013 - British Journal for the Philosophy of Science 64 (3):589-608.
    A major debate in the philosophy of biology centers on the question of how we should understand the causal structure of natural selection. This debate is polarized into the causal and statistical positions. The main arguments from the statistical side are that a causal construal of the theory of natural selection's central concept, fitness, either (i) leads to inaccurate predictions about population dynamics, or (ii) leads to an incoherent set of causal commitments. In this essay, I argue that neither (...)

  20. Adjacent Ramsey Theory.Harvey M. Friedman - unknown
    Let k ≥ 2 and f:Nk Æ [1,k] and n ≥ 1 be such that there is no x1 < ... < xk+1 £ n such that f(x1,...,xk) = f(x1,...,xk+1). Then we want to find g:Nk+1 Æ [1,3] such that there is no x1 < ... < xk+2 £ n such that g(x1,...,xk+1) = g(x2,...,xk+2). This reducees adjacent Ramsey in k dimensions with k colors to adjacent Ramsey in k+1 dimensions with 3 colors.

    It is known that for two given countable sets of unary relations A and B on ω there exists an infinite set H ⫅ ω on which A and B are the same. This result can be used to generate counterexamples in expressibility theory. We examine the sharpness of this result.

  22. The Causal Structure of Evolutionary Theory.Grant Ramsey - 2016 - Australasian Journal of Philosophy 94 (3):421-434.
    One contentious debate in the philosophy of biology is that between the statisticalists and causalists. The former understand core evolutionary concepts like fitness and selection to be mere statistical summaries of underlying causal processes. In this view, evolutionary changes cannot be causally explained by selection or fitness. The causalist side, on the other hand, holds that populations can change in response to selection—one can cite fitness differences or driftability in causal explanations of evolutionary change. But, on the causalist side, it (...)

    Is Organismic Fitness at the Basis of Evolutionary Theory?Charles H. Pence & Grant Ramsey - 2015 - Philosophy of Science 82 (5):1081-1091.
    Fitness is a central theoretical concept in evolutionary theory. Despite its importance, much debate has occurred over how to conceptualize and formalize fitness. One point of debate concerns the roles of organismic and trait fitness. In a recent addition to this debate, Elliott Sober argues that trait fitness is the central fitness concept, and that organismic fitness is of little value. In this paper, by contrast, we argue that it is organismic fitness that lies at the bases of both (...)

    Integrating Social Cognition Into Domain‐General Control: Interactive Activation and Competition for the Control of Action (ICON).Robert Ward & Richard Ramsey - 2024 - Cognitive Science 48 (2):e13415.
    Social cognition differs from general cognition in its focus on understanding, perceiving, and interpreting social information. However, we argue that the significance of domain‐general processes for controlling cognition has been historically undervalued in social cognition and social neuroscience research. We suggest much of social cognition can be characterized as specialized feature representations supported by domain‐general cognitive control systems. To test this proposal, we develop a comprehensive working model, based on an interactive activation and competition architecture and applied to the control (...)

    Towards an Expanded Epistemology for Approximations.Jeffry L. Ramsey - 1992 - PSA: Proceedings of the Biennial Meeting of the Philosophy of Science Association 1992:154 - 164.
    By stressing the act rather than the relation of approximation, I argue that the magnitude of the error introduced should not be used as the sole criterion for judging the worth of the approximation. Magnitude is a necessary but not sufficient condition for such a judgement. Controllability, the absence of cancelling errors, and the approximation's justification are also important criteria to consider when praising or blaming an approximation. Boltzmann's discussion of the types of approximations used in the kinetic theory (...)

    The Semiosis of “Side Effects” in Genetic Interventions.Ramsey Affifi - 2016 - Biosemiotics 9 (3):345-364.
    Genetic interventions, which include transgenic engineering, gene editing, and other forms of genome modification aimed at altering the information “in” the genetic code, are rapidly increasing in power and scale. Biosemiotics offers unique tools for understanding the nature, risks, scope, and prospects of such technologies, though few in the community have turned their attention specifically in this direction. Bruni is an important exception. In this paper, I examine how we frame the concept of “side effects” that result from genetic interventions (...)

    Individual differences in word senses.Rachel E. Ramsey - 2022 - Cognitive Linguistics 33 (1):65-93.
    Individual differences and polysemy have rich literatures in cognitive linguistics, but little is said about the prospect of individual differences in polysemy. This article reports an investigation that sought to establish whether people vary in the senses of a polysemous word that they find meaningful, and to develop a novel methodology to study polysemy. The methodology combined established tools: sentence-sorting tasks, a rarely used statistical model of inter-participant agreement, and network visualisation. Two hundred and five English-speaking participants completed one of (...)

  30. Rethinking Intuition: The Psychology of Intuition and its Role in Philosophical Inquiry.Michael Raymond DePaul & William M. Ramsey (eds.) - 1998 - Rowman & Littlefield Publishers.
    Ancients and moderns alike have constructed arguments and assessed theories on the basis of common sense and intuitive judgments. Yet, despite the important role intuitions play in philosophy, there has been little reflection on fundamental questions concerning the sort of data intuitions provide, how they are supposed to lead us to the truth, and why we should treat them as important. In addition, recent psychological research seems to pose serious challenges to traditional intuition-driven philosophical inquiry. Rethinking Intuition brings together a (...)

    Construction by reduction.Jeffry L. Ramsey - 1995 - Philosophy of Science 62 (1):1-20.
    Scientists employ a variety of procedures to eliminate degrees of freedom from computationally and/or analytically intractable equations. In the process, they often construct new models and discover new concepts, laws and functional relations. I argue these procedures embody a central notion of reduction, namely, the containment of one structure within another. However, their inclusion in the philosophical concept of reduction necessitates a reevaluation of many standard assumptions about the ontological, epistemological and functional features of a reduction. On the basis of (...)

    Fitness plays many roles throughout evolutionary theory, from a measure of populations in the wild to a central element in abstract theoretical presentations of natural selection. It has thus been the subject of an extensive philosophical literature, which has primarily centered on the way to understand the relationship between fitness values and reproductive outcomes. If fitness is a probabilistic or statistical quantity, how is it to be defined in general theoretical contexts? How can it be measured? Can a single (...)

    This argument explores transcultural commonalities among civic arguments from divination in global antiquity. In the ancient world, proponents engaged in kisceral arguments deriving from divinatory signs: arguments ex divinatione regarding prospective civic action. Under ideal circumstances, their aim was to help insure that the collective action of human political organizations was aligned with the natural synchrony of the cosmos. Thus, civic arguments from divination were employed to anticipate the future’s course based on the signs the system produced holistically. In ancient (...)

    Beyond Numerical and Causal Accuracy: Expanding the Set of Justificational Criteria.Jeffry L. Ramsey - 1990 - PSA: Proceedings of the Biennial Meeting of the Philosophy of Science Association 1990:485 - 499.
    I argue that numerical and causal accuracy arguments can be successful only if: (1) the theories in use are known to be true, (2) computational difficulties do not exist, and (3) the experimental data are stable and resolved. When any one or more of these assumptions are not satisfied, additional justificational considerations must be invoked. I illustrate the need for range of validity and intelligibility claims with examples drawn from chemical kinetics. My arguments suggest that the realist and anti-realist accounts (...)

    According to the modern synthesis, evolution is the gradual change of gene frequencies in a population. The MS is closely allied to adaptationist explanations of phenotypes, where organismic form and behavior is treated as previously selected for and owes its genesis to some remote past. However, some new theories of evolution broadly aligned with the extended evolutionary synthesis, in particular developmental plasticity theory and niche construction theory, foreground the fact that evolution is sometimes much more rapid than previously (...)

    Fitness is a central concept in evolutionary theory. Just as it is central to biological evolution, so, it seems, it should be central to cultural evolutionary theory. But importing the biological fitness concept to CET is no straightforward task—there are many features unique to cultural evolution that make this difficult. This has led some theorists to argue that there are fundamental problems with cultural fitness that render it hopelessly confused. In this essay, we defend the coherency of cultural (...)

    Exact saturation in pseudo-elementary classes for simple and stable theories.Itay Kaplan, Nicholas Ramsey & Saharon Shelah - 2022 - Journal of Mathematical Logic 23 (2).
    We use exact saturation to study the complexity of unstable theories, showing that a variant of this notion called pseudo-elementary class (PC)-exact saturation meaningfully reflects combinatorial dividing lines. We study PC-exact saturation for stable and simple theories. Among other results, we show that PC-exact saturation characterizes the stability cardinals of size at least continuum of a countable stable theory and, additionally, that simple unstable theories have PC-exact saturation at singular cardinals satisfying mild set-theoretic hypotheses. This had previously been open (...)

    Shut-Up and Listen: Implications and Possibilities of Albert Memmi’s Characteristics of Colonization Upon the “Natural World”.Sean Blenkinsop, Ramsey Affifi, Laura Piersol & Michael De Danann Sitka-Spruce - 2017 - Studies in Philosophy and Education 36 (3):349-365.
    This paper begins by exploring the anti-colonial work of Tunisian scholar Albert Memmi in his classic book The Colonizer and the Colonized and determining whether the characteristics of colonization that he names can be successfully applied to the current relationship between modern humans and the “natural world”.
