The biological sciences have become increasingly reliant on so-called 'model organisms'. I argue that in this domain, the concept of a descriptive model is essential for understanding scientific practice. Using a case study, I show how such a model was formulated in a preexplanatory context for subsequent use as a prototype from which explanations ultimately may be generated both within the immediate domain of the original model and in additional, related domains. To develop this concept of a descriptive model, I (...) focus on use of the nematode worm Caenorhabditis elegans and the wiring diagrams that were developed as models of its neural structure. In addition, implications of the concept of a descriptive model, particularly its relevance for the data-phenomena distinction as well as its relation to long-standing debates on realism, are briefly examined.

This book investigates a number of central problems in the philosophy of Charles Peirce grouped around the realism of his semiotics: the issue of how sign systems are developed and used in the investigation of reality. Thus, it deals with the precise character of Peirce's realism; with Peirce's special notion of propositions as signs which, at the same time, denote and describe the same object. It deals with diagrams as signs which depict more or less abstract states-of-affairs, facilitating reasoning about (...) them; with assertions as public claims about the truth of propositions. It deals with iconicity in logic, the issue of self-control in reasoning, dependences between phenomena in their realist descriptions. A number of chapters deal with applied semiotics: with biosemiotic sign use among pre-human organisms: the multimedia combination of pictorial and linguistic information in human semiotic genres like cartoons, posters, poetry, monuments. All in all, the book makes a strong case for the actual relevance of Peirce's realist semiotics. (shrink)

In his 1903 Syllabus, Charles S. Peirce makes a distinction between icons and iconic signs, or hypoicons, and briefly introduces a division of the latter into images, diagrams, and metaphors. Peirce scholars have tried to make better sense of those concepts by understanding iconic signs in the context of the ten classes of signs described in the same Syllabus. We will argue, however, that the three kinds of hypoicons can better be understood in the context of Peirce's sixty-six classes of (...) signs. We analyze examples of hypoicons taken from the field of information design, describing them in the framework of the sixty-six classes, and discuss the consequences of those descriptions to the debate about the order of determination of the 10 trichotomies that form those classes.

We all intuitively know what a diagram is, and still it is surprisingly difficult to describe it as a semiotic function or type. In this article, we present four groups of hypotheses in view of a clarification. We hypothesize: (1) That diagrams are signs of a distinct type, unknown to classical semiotics; (2) That the elementary graphs of a diagram are all derived fromlines and pointsintopologicalmental spaces. The mind applies these diagrammatic spaces to referential spaces in many ways, (...) but basically through conceptual integration (blending). The mind blends topology and reference, which makes the topology unnoticeable; (3) That elementary diagrammatic graphs constitute a natural, phenomenological, spatiotemporal, figurative and dynamic but informal geometry in the embodied, thinking mind; (4) That diagrammatic signs are the active components of the abstract mental figuration in working memory that accompany perception and deliver the schematizing ideas which invest and connect our categories and construe proper descriptive, narrative, patterns of inferentialthoughtand programs of sensorimotor and social action.

In his article “Insight: Genesis and Ongoing Context,” Fred Crowe calls out Lonergan’s line “the diagram is more important than…is ordinarily believed” as the “philosophical understatement of the century.” Sixteen pages later he identifies elaborating an invariant cognitional theory to underlie generalized emergent probability and thus “the immanent order of the universe of proportionate being,” as “our challenge,” “but given the difficulty” he does not “see any prospect for an immediate answer.” Could this have something to do with the (...) lack of a comprehensive diagram of cognitional theory? Appendix A of The Boston College Lectures on Mathematical Logic and Existentialism offers diagrams of the dynamics of knowing and doing perhaps copied from Lonergan’s own blackboard work, but they do not distinguish explanatory and descriptive insights, let alone statistical insights, and do not illustrate the pull upwards or the fusing of routinized insights. Before we can effectively relate cognitional theory to generalized emergent probability, we must have an adequately rigorous and precise cognitional theory. I firmly believe in the truth of Lonergan’s fundamental insights, but in order to rigorously undergird generalized emergent probability there are many pertinent questions about his cognitional theory which must be asked and answered. In this paper I (1) review some of Lonergan’s attempts to diagram cognitional theory and discuss what insights they do and do not express, (2) elaborate and defend principles for making our formulations of insight into insight rigorous and clear, and (3) attempt to build up a diagram which makes full use of those principles in a maximally expressive way.

Essays and detailed descriptions are built along a central axis tracing Eisenman's career. Project profiles are organized according to their "generating motif": the interiority of architecture, or projects generated by the internal forces of shapes and forms; and the exteriority of architecture, projects governed by external forces such as site and scientific process.

Translations across symbolic forms necessarily involve shifts and transformations of meaning due to the logic of the medium. They challenge us to examine fundamental metaphors as an aspect of design reasoning, particularly in relation to the construction of spatial relationships and meanings. They also involve the exploration of diagrams as a way of moving from the space of linguistic description to architectural space where topology and visual image are tightly interfaced. In this paper, Terragni's unrealized design for a monument (...) to Dante, which projects The Divine Comedy into an architectural schema is examined as a case study. The Divine Comedy is treated as an expanded body of work that includes, in addition to the original text, a multitude of paintings, as well as Terragni's project. The paper draws a distinction between transformations of meaning that arise of necessity due to the internal logic of symbolic forms and transformations which manifest specific design intentions. The Divine Comedy with its compositional, numerological, and descriptive attributes forms the program for the architectural project. Nevertheless, as in any project, the program does not, in itself, generate architecture. This paper shows that in the Danteum project three major operations are involved in design synthesis. The first inflects the familiar metaphor of the column as a body. The second uses recursive 'extreme to mean ratio' proportions to establish nesting, repetition and scaling, and through these a sense of unity. The third uses a pattern of overlapping squares so as to create a dialogue between strongly differentiated interiors and transitional zones. These operations in conjunction with the compositional and narrative aspects of the poem interpreted as program make the translation from linguistic space to architectural space possible. Thus, in this case, design formulation is not based on a single metaphor, but rather on a system of metaphors working together to bring physical elements, spatial relationships and design operations within a coherent framework of design reasoning.

The aim of this article is to clarify how Husserl applies his formal ontology to the constitution of immanent temporality. By doing so, my objective is to unravel the relationships between the phases of this temporality that make up a unit—that is, the relationship between protentions and retentions and a proto-impression that gives rise to the temporal moment “now” in an experience of the immanent consciousness. In connection with this reconstruction, I will attempt to clarify Husserl’s definition of time as (...) a “one-dimensional orthoid multiplicity,” the roots of which lie in Riemann’s work. I interpret Husserl’s description as a model for the description of the phenomenon of time. Its nature as a model seems to unfold with the problem of the time diagram. Which diagram best represents the constitution of immanent temporality? Larrabee has discussed this issue, and I propose that the best interpretation of the diagram is to consider it as applying to a spherical surface rather than a flat one. This interpretation allows us to account for the multiple relationships among presentations, memories, and other presentifications in an empirically appropriate manner while at the same time providing us with another vision of Husserl’s consciousness, which allows us to reconsider the relationship between subjectivity and objectivity.

In Baghdad in the mid twelfth century Abū al-Barakāt proposes a radical new procedure for finding the conclusions of premise-pairs in syllogistic logic, and for identifying those premise-pairs that have no conclusions. The procedure makes no use of features of the standard Aristotelian apparatus, such as conversions or syllogistic figures. In place of these al-Barakāt writes out pages of diagrams consisting of labelled horizontal lines. He gives no instructions and no proof that the procedure will yield correct results. So the (...) reader has to work out what his procedure is and whether it is correct. The procedure turns out to be insightful and entirely correct, but this paper may be the first study to give a full description of the procedure and a rigorous proof of its correctness. (shrink)

The usual metaphor for time is a flow. Edmund Husserl, in describing experience of our inner temporality, uses the term often: Fluss. In the final three decades of his life (1900s to 1930s), he gives us a well-articulated theory of time, especially the experience of its ongoingness and of our- selves in the processing of time. He refers to this latter, our immanent temporality, as a "flux" or flow and thus calls up the image of the river moving along with (...) its contents comprised in that flowing, gaining their fluent qualities from it. Yet Husserl's theory is not limited to a mechanistic understanding of flow as pure series, but in fact incorporates both a serial- ized aspect and a decentering, highly complex aspect of inner time-con- sciousness. The theory, then, requires a new metaphor, a re-mapping from serialistic diagrams to more dynamic ones. The challenge lies not only in achieving this re-mapping, but in showing the relation of dynamic diagrams to the serialistic ones that are still vital to the full descriptions of inner time- consciousness.

Yi Hwang, better known by his pen name T'oegye, is generally considered Korea's preeminent Neo-Confucian scholar. The Ten Diagrams on Sage Learning is his final masterpiece, a distillation of the learning and practice of a lifetime, and one of the most important works of Korean Neo-Confucianism. In it he crystallized the essence of Neo-Confucian philosophy and spiritual practice in ten brief chapters that begin with the grand vision of the universe and conclude with a description of a well-lived day. (...) In To Become a Sage, Michael Kalton supplements a superb translation of this pivotal text with useful commentary that will greatly enhance its value and interest to the lay reader. The Ten Diagrams is the first complete primary text of Korean Neo-Confucianism to be translated into English. Korea's Yi Dynasty, the only East Asian regime founded exclusively under Neo-Confucian auspices, was unique in its allegiance to the orthodox Ch'eng Chu school, predominant in China, Korea, and Japan. Although the Ten Diagrams is a relatively short work, it fully presents the entire vision of Neo-Confucianism as framed in that school. Kalton provides a brief history of Neo-Confucianism in China and Korea as well as commentary that includes extensive passages from T'oegye's voluminous personal correspondence. These annotations expand the meaning distilled in each chapter. They help the uninitiated reader understand the basic elements of the complex Ch'eng Chu school of Neo-Confucianism, while enabling the scholar to distinguish characteristic aspects of Korean Neo-Confucianism as presented in the thought of the nation's leading philosopher of the time.

Hans Reichenbach’s posthumous book The Direction of Time ends somewhere between Socratic aporia and historical irony. Prompted by Feynman’s diagrammatic formulation of quantum electrodynamics, Reichenbach eventually abandoned the delicate balancing between the macroscopic foundation of the direction of time and microscopic descriptions of time order undertaken throughout the previous chapters in favor of an exclusively macroscopic theory that he had vehemently rejected in the 1920s. I analyze Reichenbach’s reasoning against the backdrop of the history of Feynman diagrams and the current (...) practice of particle physics. Building upon the debates about processes and conserved quantities between Wesley Salmon and Phil Dowe in the 1990s, and the exchange between Reichenbach and the gestalt theorist Kurt Lewin during the 1920s about topology and genidentity, I investigate whether the aporia about local time order could be avoided by following a strategy that Reichenbach adopted elsewhere in the book and develop a notion of functional genidentity that captures the practice of present-day elementary particle physics and the fact that Feynman diagrams have to be understood in the context of a complex mathematical description of scattering processes.

Algebraic/topological descriptions of living processes are indispensable to the understanding of both biological and cognitive functions. This paper presents a fundamental algebraic description of living/cognitive processes and exposes its inherent ambiguity. Since ambiguity is forbidden to computation, no computational description can lend insight to inherently ambiguous processes. The impredicativity of these models is not a flaw, but is, rather, their strength. It enables us to reason with ambiguous mathematical representations of ambiguous natural processes. The noncomputability of these structures (...) means computerized simulacra of them are uninformative of their key properties. This leads to the question of how we should reason about them. That question is answered in this paper by presenting an example of such reasoning, the demonstration of a topological strategy for understanding how the fundamental structure can form itself from within itself.

This work is an introductory textbook for deductive logic being primarily concerned with truth-functional logic, but also containing an introduction to syllogisms with the application of Venn diagrams, an introduction to quantification theory, and a brief discussion of axiom systems. Harrison employs six logical operators in his truth-functional calculus, including both inclusive and exclusive disjunction. The six operators are initially defined by truth tables, but in the natural deduction presentation negation and conjunction are taken as primitive and the other connectives (...) are defined in terms of these two. The conditional and indirect methods of proof are included with the approach being essentially the same as that given in Copi’s Symbolic Logic. Categorical statements and syllogisms are analyzed from both hypothetical and existential viewpoints. The treatment of quantification theory includes two-place predicates and employs the four standard rules for generalization and instantiation. The book contains an abundance of explanations, examples, and exercises. Selected answers, usually for the odd numbered problems, are given in an appendix.—T. G. N. (shrink)

Invasion ecology addresses the spread of species outside of their native ranges. A central aim of this field is to find mechanistic explanations for why species are able to establish and spread in an area in which they did not evolve. Usually it remains unclear, however, what exactly is meant by ‘mechanistic explanation’ or ‘mechanism’. The paper argues that the field can benefit from the philosophical discussion of what a mechanism is. Based on conceptions of mechanisms as processes in concrete (...) systems, causal mechanisms can be defined as one type of mechanism, representing recurring networks of causal relationships. With the example of a well-known hypothesized mechanism in invasion ecology, namely enemy release, the paper demonstrates how such causal mechanisms can be depicted as causal network diagrams. This approach could facilitate the development of step-by-step explanations, enhance clear argumentation and allow for more precise linkage of empirical tests to theory. Challenges to assessing the empirical relevance of hypothesized mechanisms are discussed, and suggestions are made concerning how the proposed approach could help in overcoming some of them.

In Book 1 of the Principia, Newton presented two different descriptions of orbital motion under the action of a central force. In Prop. 1, he described this motion as a limit of the action of a sequence of periodic force impulses, while in Prop. 6, he described it by the deviation from inertial motion due to a continuous force. From the start, however, the equivalence of these two descriptions has been the subject of controversies. Perhaps the earliest one was the (...) famous discussion from December 1704 to 1706 between Leibniz and the French mathematician Pierre Varignon. But confusion about this subject has remained up to the present time. Recently, Pourciau has rekindled these controversies in an article in this journal, by arguing that “Newton never tested the validity of the equivalency of his two descriptions because he does not see that his assumption could be questioned. And yet the validity of this unseen and untested equivalence assumption is crucial to Newton’s most basic conclusions concerning one-body motion” (Pourciau in Arch Hist Exact Sci 58:283–321, 2004, 295). But several revisions of Props. 1 and 6 that Newton made after the publication in 1687 of the first edition of the Principia reveal that he did become concerned to provide mathematical proof for the equivalence of his seemingly different descriptions of orbital motion in these two propositions. In this article, we present the evidence that in the second and third edition of the Principia, Newton gave valid demonstrations of this equivalence that are encapsulated in a novel diagram discussed in Sect. 4.

An application of diagrams for separating modes of theory development.

Classic and canon -- Description -- Categories -- Metaphors -- Diagrams -- Cynicism and scepticism : two intellectual styles -- Sociological theory and the art of living.

Maps, notes, descriptions, diagrams, flowcharts, photographs, paintings, and prints, all, in one way or another, manage to be about things or stand for them. This article looks at three ways in which philosophers have explained the way that pictures represent the world. It starts by describing some leading perceptual accounts and then surveys contemporary content and structural alternatives.

Pictorial representations such as diagrams and figures are widely used in scientific literature for explanatory and descriptive purposes. The intuitive nature of pictorial representations coupled with texts foster a better understanding of the objects of study. Biological mechanisms and processes can be clearly illustrated and grasped in pictures. I argue that pictorial representations describe biological phenomena by telling stories. I elaborate on the role of narrative structures of pictures in the frontier research using a case study in immunology. I articulate (...) that pictures with an inherent narrative structure are crucial in biological sciences. (shrink)

Tagging is the phenomenon in which regions of a picture, map, or diagram are annotated with words or other symbols, to provide descriptive information about a depicted object. The interpretive principles that govern tagged images are not well understood, due in part to the difficulty of integrating pictorial and linguistic semantic rules. Rather than directly combining these rules, I propose to use the framework of perspectival feature maps as an intermediary representation of content, in which the outputs of pictorial (...) and linguistic interpretation may be assimilated. The result is a simple and compositional semantics for tagged images. (shrink)

This article describes a descriptive-qualitative method for analyzing and reviewing several textbooks for high school as samples commonly used by teachers and students in their teaching–learning to reveal possible misconceptions. This study focused on the subjects of quantum numbers and electronic configuration. From the advanced literature review to analyze the samples the occurrence of various misconceptions was noted. All textbooks described correctly the four symbols of quantum numbers, but none correlates correctly the magnetic-angular quantum number to the Cartesian labeled orbitals. (...) All textbooks consider mistakenly the meaning of aufbau as the building-up energy of orbitals by following (n + ℓ, n) rules on describing the electronic configuration for all atoms. Only one textbook states that the electronic configuration of transition metal atoms (3d series) can be described in the following order of shell (n), thus giving rise to two types of electronic configurations, [Ar] 3d 4s (Type I) beside [Ar] 4s 3d (Type II), leading further misconception. All textbooks described favorably an unpaired electron of ms = + ½ due to the specific agreement, which is a potential misconception in applying Hund’s rule. In drawing the diagram boxes of orbitals, they are arranged in increasing or decreasing the numeric mℓ, due to the specific agreement, and again leading to a potential misconception on describing the quantum number of electrons issued. Three textbooks introduced the terms of the last and the xth electron associated with the quantum numbers, leading to serious further misconceptions. No books stated that the ordering energy of the (n + ℓ, n) rule is true only for the first twenty atoms. (shrink)

A new description of gravitational motion will be proposed. It is part of the proper time formulation of physics as presented on the IARD 2000 conference. According to this formulation the proper time of an object is taken as its fourth coordinate. As a consequence, one obtains a circular space–time diagram where distances are measured with the Euclidean metric. The relativistic factor turns out to be of simple goniometric origin. It further follows that the Lagrangian for gravitational dynamics (...) does not require an interpretation in terms of curvature of space–time. The flat space model for gravitational dynamics leads to the correct predictions for the bending of light, the perihelion shift of Mercury and gravitational red-shift. The new theory is free of singularities. More important, the new formulation of gravitational dynamics restores the validity of the principle of addition of potentials. One therefore can find solutions for static gravitational configurations for which it is difficult to find the solution of the corresponding Einstein equations. The method will be illustrated by means of the orbital precession for non-spherical stellar mass distributions. In case of the bipole mass distribution the agreement with the predictions of the general theory of relativity is very striking. Nevertheless, the new model is far more simple. (shrink)

The first systematic exposition of all the central topics in the philosophy of logic, Susan Haack's book has established an international reputation for its accessibility, clarity, conciseness, orderliness, and range as well as for its thorough scholarship and careful analyses. Haack discusses the scope and purpose of logic, validity, truth-functions, quantification and ontology, names, descriptions, truth, truth-bearers, the set-theoretical and semantic paradoxes, and modality. She also explores the motivations for a whole range of non-classical systems of logic, including many-valued logics, (...) fuzzy logic, moddal and tense logics, and relevance logics. Persupposing only an elementary knowledge of formal logic, this book includes many useful summary tables and diagrams, as well as a helpful glossary of technical terms. Wide-ranging, informative, and eminently readable, this book has proven a valuable resource for generations of students and scholars in a variety of disciplines outside philosophy needing guidance on the philosophy of logic.

BERTRAND RUSSELL ON MODALITY AND LOGICAL RELEVANCE - SECOND EDITION of 2015. Praise for the first edition of 1999: "In the twenty-nine years since Russell's death, much of the major scholarship has drawn heavily on his manuscripts and unpublished correspondence. The author shows that the published Russell is capable of new interpretations; in particular, that modal notions such as possibility have a greater place in various aspects of his logical and philosophical thought than has been previously imagined." -Ivor Grattan-Guinness, Foreword (...) to the first edition. EXCERPT FROM PUBLISHED REVIEW: "Dejnožka's book is the first full-length study of modality in Russell. It is useful for its very full survey of passages in which Russell makes use of or alludes to modal notions. Dejnožka's command of Russell's huge output is indeed impressive and his utilization of it thorough...." - Nicholas Griffin, Studia Logica. EXCERPT FROM PUBLISHED REVIEW: "Dejnožka's book raises a very important point in the history of formal logic. Until now the major studies on this topic have drawn heavily on the development of classical logic as standardized by Gottlob Frege and Bertrand Russell. Dejnožka challenges the reader to open his mind for a new interpretation of Russell's work, in particular that modal and relevance notions have a greater place in his philosophy of logic than has been stressed before.... "Dejnožka rightly observes that many of Russell's insights on modality are a result of his discussions with Hugh MacColl, who was indeed the first to seriously attempt to develop formal modal logic. This particularly applies to Russell's conception of a modal logic without modal operators....That is, classical logic can be used to simulate modal expressions. Thus, the notions of (logical) necessity and possibility are not 'fundamental notions'....On this basis, Dejnožka develops a higher level of modality, where the quantification scope extends to the predicates yielding what Russell calls 'fully general propositions'.... "The best studied translation method is known as the standard translation, and it is quite compatible with Dejnožka's suggestions.... "Dejnožka's book is full of material which stimulates [one] to rethink Russell's philosophy of logic and...it is greatly to the author's credit that he brings to light such a wealth of crucial issues in the history and philosophy of logic. - Shahid Rahman, History and Philosophy of Logic. BOOK DESCRIPTION: This book is the only exhaustive study of Russell on modality and logical relevance ever written. This is the second edition, revised over a period of over sixteen years, and over twice as long. Russell initially rejects the possibility of a modal logic in an unpublished paper written ca. 1903-05 and read to an audience in 1905. But the very next year, he adopts the theory of modality he had rejected, and he repeats that theory in published works for many years to come. That theory, together with other texts scattered among Russell's writings, implies eight modal logics which Russell himself never expressly accepted. And Russell's express acceptance of the early Wittgenstein's theory of entailment ("following from") as truth-ground containment implies a deductive relevance logic in Russell's writings which Russell himself never expressly accepted. The book ends with a look at John Maynard Keynes and Anglo-American evidence law as the origins of Russell's theory of probability as degree of logical relevance. Thus the book is written toward the reunion of modern classical logicians with modal logicians and relevantists. On the reunion of modern classical logicians with relevantists, please see also The Concept of Relevance and the Logic Diagram Tradition (2012). Thus I hope to have created two new fields of Russell studies. I may have created a new legal field as well: the history of logical relevance in evidence law: 132 pages (368-500) in chapter 10.

Most of us create and use a panoply of non-sentential representations throughout our ordinary lives: we regularly use maps to navigate, charts to keep track of complex patterns of data, and diagrams to visualize logical and causal relations among states of affairs. But philosophers typically pay little attention to such representations, focusing almost exclusively on language instead. In particular, when theorizing about the mind, many philosophers assume that there is a very tight mapping between language and thought. Some analyze utterances (...) as the outer vocalizations of inner thoughts (e.g. Grice 1957, Devitt 2005), while others treat thought as a form of inner speech (e.g. Sellars 1956/1997, Carruthers 2002). But even philosophers who take no stand on the relative priority of language and thought still tend to individuate mental states in terms of the sentences we use to ascribe them. Indeed, Dummett (1993) claims that it is constitutive of analytic philosophy that it approaches the mind by way of language. In many ways, this linguistic model is salutary. Our thoughts are often intimately intertwined with their linguistic expression, and public language does provide a comparatively tractable proxy for, and a window into, the messier realm of thought. However, an exclusive focus on thought as it is expressed in language threatens to leave other sorts of thought unexplained, or even to blind us to their possibility. In particular, many cognitive ethologists and psychologists find it useful to talk about humans, chimpanzees, birds, rats, and even bees as employing cognitive maps. We need to make sense of this way of talking about minds as well as more familiar sentential descriptions. In what follows, I investigate the theoretical and practical possibility of non-sentential thought. Ultimately, I am most interested in the contours of distinctively human thought: what forms does human thought take, and how do those different forms interact? How does human thought compare with that of other animals? In this essay, however, I focus on a narrower and more basic theoretical question: could thought occur in maps? Many philosophers are convinced that in some important sense, thought per se must be language-like.. (shrink)

Highly praised for its clarity and rich exposition, this history of philosophy text illustrates philosophy as a process and not just a collection of opinions or conclusions. Rather than simply reporting the positions of a given philosopher, Lawhead's prose assists students in retracing the thinker's intellectual journey. Students are invited to engage with each philosopher's intellectual process, drawing connections with their own lives and cultures. Metaphors, analogies, vivid images, concrete examples, common experiences, and diagrams demonstrate the concrete relevance of abstract (...) arguments and their practical implications for contemporary society. This fourth edition of VOYAGE OF DISCOVERY: A HISTORICAL INTRODUCTION TO PHILOSOPHY features new historical profiles and/or works representing such philosophers as Plato, St. Thomas Aquinas, Simone de Beauvoir, and Martha Nussbaum, among others.

Discussion of philosophical issues (...) concerning the development of modal logic is woven into the text. The book uses natural deduction systems and also includes a diagram technique that extends the method of truth trees to modal logic. This feature provides a foundation for a novel method for showing completeness, one that is easy to extend to systems that include quantifiers. (shrink)

In an effort to reassess the status of Phenomenology of Perception and its relation to The Visible and the Invisible, this essay argues that Merleau-Ponty's engagement with Husserl's text and his discussion of the “field of presence” in La temporalité are intended to think through the field in which time makes its appearance as one of passage. Time does not show itself as presence or in the present but manifests itself as Ablauf, as lapse or flow, an écoulement that is (...) simultaneously an explosion, an éclatement. Merleau-Ponty's account of temporality in these pages is thus legible as recovering the primordial experience of time as a self-differentiating déhiscence in its dual power of articulation and erosion. Time is thus simultaneously the vehicle of the world's appearance and of its “disarticulation”, the passage of a rhythm of affirmation and disintegration. Merleau-Ponty's account of temporality in Phenomenology of Perception is oblique, somewhat fragmentary and circuitous.11 References to Merleau-Ponty's works cite the French followed by the English translation. I will use the abbreviation PhP for Phenomenology of Perception and VI for The Visible and the Invisible. Other texts by Merleau-Ponty will be referenced by the title. References to Husserl and Heidegger use the German followed by the translation. I will use the abbreviations ZB for the Zeitbewußtsein lectures; FT for Formale und transzendentale Logik; EU for Erfahrung und Urteil; and SZ for Sein und Zeit. View all notes While of course this phenomenon comes under close scrutiny in La temporalité, a brief inspection of this text as a whole finds it to be virtually everywhere.22 The theme of temporality is introduced as early as the Preface to Part I, “Experience and Objective Thought” and appears again in almost every subsequent chapter: the first chapter of Part I ; in his discussion on number blindness and Goldstein's patient known as Schneider in La spatialité du corps et la motricité ; in the sexuality chapter ; in the discussion of memory in La corps comme expression et la parole ; in Le sentir ; in the discussion of depth in L'espace ; in La chose et le monde naturel ; in Autrui et le monde humain and in Le cogito. Rather than providing the perhaps much called for synopsis of these scattered accounts of time or trying to locate a unified account in Phenomenology of Perception through such a synopsis, this essay will focus only on La temporalité, particularly the discussion of Husserl's diagram from the Zeitbewußtsein and the “champ de présence”. View all notes It is this apparent ubiquity that will motivate scholars such as Renaud Barbaras to claim that “… the entire structure of Phenomenology of Perception rests on a chapter devoted to temporality”.33 Barbaras The Being of the Phenomenon, 218. View all notes In spite of this ubiquity and apparent centrality, however, the treatment of temporality seems to neglect a systematic and thoroughgoing approach, and whether this work manages to address this theme with a sufficient degree of rigor remains open to debate. Furthermore, beyond the scattered and fragmented appearance of temporality in the text, the chapter devoted to its exploration contains numerous, well-recognized problems.44 Merleau-Ponty's misinterpretation of Bergson in this chapter has received much warranted attention. Alia Al-Saji, for example, has criticized Merleau-Ponty's account of temporality in this chapter of Phenomenology of Perception for this misreading as well as its perhaps too uncritical infatuation with Husserl and his emphasis on presence. See Lawlor Thinking Through French Philosophy, Al-Saji “The Temporality of Life” and “A Past Which Has Never Been Present” and Barbaras “The Turn of Experience”. View all notes Among these difficulties, Merleau-Ponty's engagement with Husserl's lectures on time-consciousness, the Vorlesungen zur Phänomenologie des inneren Zeitbewußtseins,55 The 1928 publication of the Zeitbewußtsein, edited by Heidegger, is what appears in the bibliography of Phenomenology of Perception. This version, from the Jahrbuch für Philosophie und phänomenologishe Forschung, as Brough notes, appears as “Part A” of Husserliana X. The notes that constitute this version of the text, furthermore, as Heidegger mentions in his preface to the Jahrbuch version and which Brough repeats were heavily edited by Husserl's assistant at the time, Edith Stein. Merleau-Ponty's references to the Zeitbewußtsein cut across various moments of the text and do not focus on one section in particular, and in fact, he actually references section 11, “Urimpression und retentionale Modifikation”/“Primal impression and retentional modification” in his discussion of the field of presence. As Al-Saji has noted, the extent to which Merleau-Ponty's account of time in La temporalité centres the account of time on “the living present” can be shown to be at play behind the misreading of Bergson. While I do not wish to dispute the specifics of her compelling reading, it is nonetheless worth noting that Al-Saji's reading of the Zeitbewußtsein only focuses on Appendix V, “Gleichzeitigkeit von Wahrnehmung und Wahrgenommenem”/“Simultaneity of Perception and the Perceived”. View all notes looms large, as it seems that his discussion of what he designates as le champ de présence or “field of presence” commits him to the ontological primacy of the present in his account of time. As a result, this earlier work appears to confine itself to a metaphysics organized around the privilege and authority of the present in establishing the structure of time.66 Leonard Lawlor has convincingly argued against this interpretation. Following the famous remark at the end of Le Sentir about “a past which has never been present”, Lawlor argues that precisely because Merleau-Ponty's critique of Bergson is a straw man – that is, because his critique of Bergson is based on a misreading – a closer inspection of Le Sentir and La temporalité shows Merleau-Ponty to be committed to the ontological primacy of an “originary” past. See Lawlor Thinking Through French Philosophy, 89. Marratto, following Lawlor, takes up the charge of a metaphysics of presence in Phenomenology of Perception in dialogue with Derrida. Marratto argues that Derrida's reading selectively overlooks “the very imporant dimensions of difference, discontinuity, and delay and non-self-presence in Merleau-Ponty's descriptions”, located particularly in the latter's theory of subjectivity. I agree with Marratto's assessment, and my aim here is to deepen it by turning in more detail to La temporalité. View all notes This apparent commitment to the ontological primacy of the present, for some readers, has also functioned as an index for tracking the revision of Phenomenology of Perception that is said to figure in The Visible and the Invisible, where a metaphysics of the present is replaced with a commitment to the primacy of an original past, signalling a significant break in the development of Merleau-Ponty's thought.77 This has bearing on the debate mentioned above as the question of temporality and Merleau-Ponty's evolving relationship with Bergson are also cited as part of the index for tracking the differences between Phenomenology of Perception and The Visible and the Invisible. What we see, according to this reading, is Merleau-Ponty move away from a more strictly phenomenological orientation of Phenomenology of Perception, an orientation that is said to adversely mediate his early, critical stance with respect to Bergson, toward a progressively less Husserlian and more Bergsonian stance in The Visible and the Invisible. While he does not specifically address Merleau-Ponty's engagement with Bergson, Marratto's reading also places a special emphasis on the significance of the past, specifically Merleau-Ponty's reference to a “past which has never been present”. It is also not my intention to enter into the question of Merleau-Ponty's relationship with Bergson. Rather, I will restrict my remarks specifically to Merleau-Ponty's engagement with Husserl and the Zeitbewußtsein in La temporalité in order to show that there are grounds for at least questioning one of the premises of the interpretation mentioned above, namely that Phenomenology of Perception is unequivocally legible as committed to the ontological primacy of the present. As will become clear later in the essay, I also dispute interpretations that would place the emphasis on the ontological primacy of an original past. For my own views on the significance of a “past which has never been present”, see Whitmoyer “The Primary Silence of the Past”. View all notes In considering the manner in which the Zeitbewußtsein figures in La temporalité and Merleau-Ponty's discussion of the field of presence, it will do to think about the parameters in which his engagement with Husserl is staged more generally. It seems that Merleau-Ponty never considered his task in terms of the perhaps false alternative of fidelity and heresy, because “any commemoration is also a betrayal”, and because the task of the interpreter is, as he famously notes, thinking through that “unthought-of element … which is wholly his [Husserl's] and yet opens out on something else”.88 Merleau-Ponty, Signes, 203/160. This methodological dictum is developed in more detail in the notes to the course offered on Husserl's Origin of Geometry in 1959–1960. “We are saying not that Husserl was that, but that Husserl was not only what they say, was also another, bearer of an unthought”. View all notes Following Merleau-Ponty's own indications, we could suggest that Husserl's text, rather than a source of orthodoxy, functions as a point of orientation through which Merleau-Ponty marks out his own theory of temporality.99 I will not, therefore, address the question of the “accuracy” of his interpretation of Husserl because, according to Merleau-Ponty himself, this question presupposes that the author, in this case Husserl, has a privileged access to his thought, as if there is some kernel or essence of what a philosopher thought that interpreters can either get right or wrong. As the remarks in “The Philosopher and His Shadow” make clear, interpretation can never really avail itself of this presupposition and in this manner the question of accuracy is precisely the wrong question. View all notes This essay argues that his discussion of the Zeitbewußtsein in Phenomenology of Perception does not offer an account of time that “centers around the living present”, as some have argued,1010 Al-Saji “A Past Which Has Never Been Present”, 42–44. View all notes but that the discussion of the field of presence and what follows are rather intended to account for the field of temporal phenomenalization – not as a presence – but as écoulement, passage and flux. Time, therefore, does not appear in the present or as presence, but manifests itself as a flow and movement that is simultaneously an éclatement, an eruption, and a self-differentiating “dehiscence”.1111 A favorite word of Merleau-Ponty, borrowed from botany, where it designates the splitting open of a seed-pod or flower as well as medicine, where it refers to the splitting open of a healed or partially healed wound. The idea here is that, in its flow and passage, time splits open in a process of differentiation – which is simultaneously a process of degeneration, decay, and what Merleau-Ponty will term in The Visible and the Invisible, “disarticulation”. View all notes Time's passage is not determined, organized and oriented in advance in accordance with a transcendental synthesis that would give it shape and form, privileging one temporal dimension over another, so much as it is understood in terms of a splitting open, or to use another favoured locution of Merleau-Ponty, a “deflagration”.1212 In Eye and Mind, Merleau-Ponty speaks of the “deflagration of being”. Metaphors of explosiveness and dissonance populate his attempt to think being otherwise than as structure, form, and stability. Here I will focus particularly on écoulement, flux and éclatement, eruption, because these are the terms he uses in his discussion of time in La temporalité. See Merleau-Ponty L’Œil et l'esprit, 64/369. View all notes To this extent, Merleau-Ponty's account of temporality in Phenomenology of Perception cannot be said to orient itself in terms of the ontological primacy of any one temporal dimension – past, present, or future – but is more accurately understood as an attempt to recover the primordial experience of time as the simultaneity of écoulement and éclatement – an account that thinks time in its dual power of phenomenalization and erosion, the “pulse [pulsation] of my existence, its systole and diastole”.1313 Merleau-Ponty PhP, 337/332. View all notes Time is the vehicle of the world's appearance, and at the same time of its “disarticulation” [désarticulation],1414 This is a term Merleau-Ponty uses in The Visible and the Invisible in a well-known working note entitled “ Transcendence – forgetting – time”. See Merleau-Ponty VI, 247/197. View all notes the vehicle through which “becoming” – rather than being – shows itself. This process of phenomenalization, precisely because it is temporal, never achieves the density of fully realized being – the sense of this becoming is never fully articulate – but is perpetually subject to a temporal erasure that necessitates its repetition and reiteration. Time, in other words, is the principle of the world's eloquence – it is that thanks to which things have and make sense and simultaneously the principle of the world's murmuring stutter, the principle through which the sense of things remains incomplete and even erodes, decays, and degenerates. To begin, I will turn to Merleau-Ponty's reading of Husserl's diagram from the Zeitbewußtsein, which opens his attempt to “arrive at authentic time”.1515 Merleau-Ponty PhP, 477/483. View all notes Rather than simply rehearsing Husserl's discussion of primal impression, retention and protention, Merleau-Ponty's analysis of the diagram provides an opportunity for raising two problems: the problem of time's representability and the problem of its synthesis. Rather than through an “act intentionality” carried out by a transcendental subjectivity, time appears in accordance with an “operative intentionality” always already under way. Turning to the section of La temporalité aptly entitled “Passive Synthesis”, we see that Merleau-Ponty's analysis of the diagram leads him to the paradox of passive synthesis and what he calls, following Husserl, “transition synthesis”. Time does not show itself punctually – time appears neither as presence nor in the present – but only in the dual movement of its flux, its écoulement, and its éclatement, its explosive, self-differentiating unfurling. These reflections, finally, bring Merleau-Ponty into dialogue with Heidegger on what the latter called the Zusammenhang des Lebens. The “unity of a life”, accordingly, is not a question of any “resolution”, but is a function of our immersion in this temporal dehiscence. The important lesson to be learned from Merleau-Ponty's engagement with Husserl's Zeitbewußtsein is not something about the ontological primacy of one temporal dimension over another but what Merleau-Ponty famously calls in The Visible and the Invisible the “passivity of our activity”1616 Merleau-Ponty VI, 270/221.

This book on modal logic is especially designed for philosophy students. It provides an accessible yet technically sound treatment of modal logic and its philosophical applications. Every effort is made to simplify the presentation by using diagrams instead of more complex mathematical apparatus. These and other innovations provide philosophers with easy access to a rich variety of topics in modal logic, including a full coverage of quantified modal logic, non-rigid designators, definite descriptions, and the de-re de-dicto distinction. Discussion of philosophical (...) issues concerning the development of modal logic is woven into the text. The book uses natural deduction systems, which are widely regarded as the easiest to teach and use. It also includes a diagram technique that extends the method of truth trees to modal logic. This provides a foundation for a novel method for showing completeness that is easy to extend to quantifiers. This second edition contains a new chapter on logics of conditionals, an updated and expanded bibliography, and is updated throughout. (shrink)

We argue that current discussions of criteria for actual causation are ill-posed in several respects. (1) The methodology of current discussions is by induction from intuitions about an infinitesimal fraction of the possible examples and counterexamples; (2) cases with larger numbers of causes generate novel puzzles; (3) "neuron" and causal Bayes net diagrams are, as deployed in discussions of actual causation, almost always ambiguous; (4) actual causation is (intuitively) relative to an initial system state since state changes are relevant, but (...) most current accounts ignore state changes through time; (5) more generally, there is no reason to think that philosophical judgements about these sorts of cases are normative; but (6) there is a dearth of relevant psychological research that bears on whether various philosophical accounts are descriptive. Our skepticism is not directed towards the possibility of a correct account of actual causation; rather, we argue that standard methods will not lead to such an account. A different approach is required. (shrink)

This handbook for advanced students explains the various applications to music of methods derived from linguistics and semiotics. The book is aimed at musicians familiar with the ordinary range of aesthetic and theoretical ideas in music; no specialized knowledge of linguistic or semiotic terminology is necessary. In the two introductory chapters, semiotics is related to the tradition of music aesthetics and to well-known works like Deryck Cooke's The Language of Music, and the methods of linguistics are explained in language intelligible (...) to musicians. There is no limitation to one school or tradition; linguistic applications not avowedly semiotic, and semiotic theories not connected with linguistics, are all included. The book gives clear and simple descriptions with ample diagrams and music examples of the 'neutral level', 'semiotic analysis', transformation and generation, structural semantics and narrative grammar, intonation theory, the ideas of C.S. Peirce, and applications in ethnomusicology. (shrink)

In recent years, academics and educators have begun to use software mapping tools for a number of education-related purposes. Typically, the tools are used to help impart critical and analytical skills to students, to enable students to see relationships between concepts, and also as a method of assessment. The common feature of all these tools is the use of diagrammatic relationships of various kinds in preference to written or verbal descriptions. Pictures and structured diagrams are thought to be more comprehensible (...) than just words, and a clearer way to illustrate understanding of complex topics. Variants of these tools are available under different names: “concept mapping”, “mind mapping” and “argument mapping”. Sometimes these terms are used synonymously. However, as this paper will demonstrate, there are clear differences in each of these mapping tools. This paper offers an outline of the various types of tool available and their advantages and disadvantages. It argues that the choice of mapping tool largely depends on the purpose or aim for which the tool is used and that the tools may well be converging to offer educators as yet unrealised and potentially complementary functions.

In approaching the question of whether groups of people can have cognitive capacities that are fundamentally different than the cognitive capacities of the individuals within the group, we lay out a Multiple, Interactive Levels of Cognitive Systems (MILCS) framework. The goal of MILCS is to explain the kinds of cognitive processes typically studied by cognitive scientists, such as perception, attention, memory, categorization, decision making, problem solving, and judgment. Rather than focusing on high-level constructs such as modules in an information processing (...) flow diagram or internal representations, MILCS focuses on mechanisms that allow systems to engage in flexible, adaptive behavior. Examples of these mechanisms are network structure-process pairs that: combine data from perception with top-down theories, achieve consistency and consensus through information exchange, selectively attend to information globally assessed as relevant, and develop specialized units from originally homogeneous networks through competition among the units. Two such systems are considered in some detail -- lateral inhibition within a network for selecting from a candidate set the option that is most attractive, and a diffusion process for accumulating evidence to reach a generally rapid and accurate decision. These system descriptions are aptly applied at multiple levels, including within and across people. These systems provide accounts that unify cognitive processes across multiple levels, can be expressed in a common vocabulary provided by network science, are inductively powerful yet appropriately constrained, and are applicable to a large number of superficially diverse cognitive systems. Given that people are typically highly motivated to participate in strong groups, cognitively resourceful people will tend to form groups that effectively employ cognitive systems at higher levels than the individuals. The impressive cognitive capacities of individual people do not eliminate the need to talk about group cognition. Instead, smart people generally form smart groups. (shrink)

A study of smooth classes whose generic structures have simple theory is carried out in a spirit similar to Hrushovski 147; Simplicity and the Lascar group, preprint, 1997) and Baldwin–Shi 1). We attach to a smooth class K0, of finite -structures a canonical inductive theory TNat, in an extension-by-definition of the language . Here TNat and the class of existentially closed models of =T+,EX, play an important role in description of the theory of the K0,-generic. We show that if (...) M is the K0,-generic then MEX. Furthermore, if this class is an elementary class then Th=Th). The investigations by Hrushovski and Pillay , provide a general theory for forking and simplicity for the nonelementary classes, and using these ideas, we show that if K0,, where {,*}, has the joint embedding property and is closed under the Independence Theorem Diagram then EX is simple. Moreover, we study cases where EX is an elementary class. We introduce the notion of semigenericity and show that if a K0,-semigeneric structure exists then EX is an elementary class and therefore the -theory of K0,-generic is near model complete. By this result we are able to give a new proof for a theorem of Baldwin and Shelah 1359). We conclude this paper by giving an example of a generic structure whose first-order theory is simple.

Illustrations: Numerous B/w Figures Description: Key questions in the history of Navya-nyaya (New Nyaya) remain unresolved: when did this school of logic begin, who was its founder, what distinguishes Navya-nyaya from Pracina-nyaya (Old Nyaya), and so on. This book attempts to answer these key questions in Part I. Part II provides a translation, analysis, and critical edition of the Lion and Tiger Definitions of Invariable Concomitance Chapter (Simha-vyaghra-laksana: LT Chapter) of the Tattva-cintamani-rahasya (TCR) of Mathuranatha (16th-17th c.). The hypothesis (...) adopted by the author with regard to the first question is that Udayana, who lived in the 11th century, is the founder of Navya-nyaya. This hypothesis is closely linked to the hypothesis offered regarding the second question, which is that the feature that distinguishes Navya-nyaya from the earlier school is its description of concepts and the structure of the world in terms of relation. Early Navya-nyaya authors, who flourished between Udayana and Gangesa (14th c.), devised specific terminology, of which delimitor (avacchedaka) and describer (niËpaka) are the most important, in order to identify or specify relation. This book attempts to illustrate the function of these and other Navya-nyaya terms from the viewpoint of relation. The main sources upon which the author has based his conclusions are Udayana s Laksanavali and the chapters on invariable concomitance or pervasion (vyapti) of the Nyaya-siddhanta-dipa (NSD) of Sasadhara (13rd-14th c.), the Tattva-cintamaÆi (TC) of Gangesa, and the TCR. Of these Sanskrit texts no scholar has worked on the Invariable Concomitance Chapter (Vyapti-vada) of the NSD in detail or the LT Chapter of the TCR. The latter chapter follows in the TCR the Five Definitions of Invariable Concomitance Chapter (Vyapti-pancaka), which Ingalls edited, translated, and analyzed in his epoch-making book Materials for the Study of Navya-Nyaya Logic (1951). One major innovation of this book made in Part II is to explain the structure of Navya-nyaya analysis by employing 86 diagrams based on the dharma-dharmin (property and property-possessor) relation, which serve as a visual aid and help readers to more easily understand the complicated structure of its analysis. The diagrams are also helpful in ascertaining how the definitions of invariable concomitance apply to individual cases and how the entities are connected in the application of the definitions. Another major innovation is: almost every sub-section of the LT Chapter of the TCR contains Mathuranatha s clarification of part of the two definitions; but this clarification does not give the definition incorporating prior clarifications and insertions; this book provides such a definition accompanied by a diagram. In other words, Part II illustrates the structure of the whole definition at every process of the clarification, which (definition) is never presented as such in Mathuranatha s text. (shrink)

This paper reports the experience of reconstructing a surveying instrument—the plane table—using the description found in Arthur Hopton’s Speculum topographicum: or The topographicall glasse : ‘Of the Plaine Table, with a description thereof, and the parts thereunto belonging’. One of the most detailed early printed descriptions of the instrument, it is illustrated with woodcut diagrams of components but no image of the complete plane table. The reconstruction process did not prove entirely straightforward. An examination of its various stages (...) reveals how Hopton’s text set out to persuade and lead the reader, rather than issuing orders to be followed exactly; the reader, left to make some decisions himself, would thus create a plane table with an element of uniqueness in its character. The role of the maker of such an instrument, even when following written instructions, was a creative and collaborative one, rather than purely passive.Keywords: Reconstruction; Instrument; Diagrams; Text; Instrument-maker; Collaboration.

The paper addresses the issue of human diagrammatic reasoning in the context of Euclidean geometry. It develops several philosophical categories which are useful for a description and an analysis of our experience while reasoning with diagrams. In particular, it draws the attention to the role of seeing-as; it analyzes its implications for proofs in Euclidean geometry and ventures the hypothesis that geometrical judgments are analytic and a priori, after all.

In the literature, Fair Trade (FT) goods are usually associated with other products differentiated by process attributes such as organic food, genetically modified (GM) food or child labour-free clothing. All of these products are regarded as credence goods. This classification refers to the simplified definition of credence goods, which describes product attributes which consumers cannot evaluate, even after having consumed the good. Focusing on the characteristics of FT goods, this article proposes a reassessment of the link between FT goods and (...) credence properties as defined by Darby and Kami. We first demonstrate that (1) the usual classification masks important particularities of FT goods compared to other goods with process attributes and (2) the full definition of credence goods may even provide a better description of the quality of FT goods. However - and this is our second theoretical contribution - the lack of consensus among experts concerning FT standards and their level of efficiency encourage us to consider FT goods as indeterminate goods as defined by Lupton. This result leads us to suggest a new typology of product attributes summarized in an innovative diagram. It sheds light on how competition between the different FT approaches works and why the FT market is still confined to a niche, if not threatened with collapse. We mainly illustrate our theoretical analysis with observations relating to the French FT market and institutions. (shrink)

in a nervous system of a given species. This chapter provides a critical perspective on the role of connectomes in neuroscientific practice and asks how the connectomic approach fits into a larger context in which network thinking permeates technology, infrastructure, social life, and the economy. In the first part of this chapter, we argue that, seen from the perspective of ongoing research, the notion of connectomes as “complete descriptions” is misguided. Our argument combines Rachel Ankeny’s analysis of neuroanatomical wiring diagrams (...) as “descriptive models” with Hans-Joerg Rheinberger’s notion of “epistemic objects,” i.e., targets of research that are still partially unknown. Combining these aspects we conclude that connectomes are constitutively epistemic objects: there just is no way to turn them into permanent and complete technical standards because the possibilities to map connection properties under different modeling assumptions are potentially inexhaustible. In the second part of the chapter, we use this understanding of connectomes as constitutively epistemic objects in order to critically assess the historical and political dimensions of current neuroscientific research. We argue that connectomics shows how the notion of the “brain as a network” has become the dominant metaphor of contemporary brain research. We further point out that this metaphor shares (potentially problematic) affinities to the form of contemporary “network societies.” We close by pointing out how the relation between connectomes and networks in society could be used in a more fruitful manner.

This paper propounds an analysis of the Husserlian problem of time through the prism of his elaboration of succeeding time-diagrams. The author focuses his reflexions on the "Lectures on Inner Time-consciousness" (1905) and at the same time on the decisive advancements of the "Bernauer Time-Manuscripts" (1917-1918). These manuscripts complete the Husserlian description of constitution of time-consciousness by the element of protentional intentionality and the "original process" with its "core"-structure (Kernstruktur), on this side of immanent temporality, and try to work (...) out the problem of the statute of the sense-data and of the self-awareness of the ultimately constitutive "flow" of consciousness.

Network motifs are small patterns of connections, found over‐represented in gene regulatory networks. An example is the negative feedback loop (e.g. factor A represses itself). This opposes its own state so that when ‘on’ it tends towards ‘off’ – and vice versa. Here, we argue that such self‐opposition, if considered dimensionlessly, is analogous to the liar paradox: ‘This statement is false’. When ‘true’ it implies ‘false’ – and vice versa. Such logical constructs have provided philosophical consternation for over 2000 years. (...) Extending the analogy, other network topologies give strikingly varying outputs over different dimensions. For example, the motif ‘A activates B and A. B inhibits A’ can give switches or oscillators with time only, or can lead to Turing‐type patterns with both space and time (spots, stripes or waves). It is argued here that the dimensionless form reduces to a variant of ‘The following statement is true. The preceding statement is false’. Thus, merely having a static topological description of a gene network can lead to a liar paradox. Network diagrams are only snapshots of dynamic biological processes and apparent paradoxes can reveal important biological mechanisms that are far from paradoxical when considered explicitly in time and space.
