Rethinking the Peircean Trichotomy of Icon, Index, and Symbol Semiotica 2016; 213: 165–175 Ersu Ding* Rethinking the Peircean trichotomy of icon, index, and symbol DOI 10.1515/sem-2015-0134 Abstract: Classification of signs into various kinds is a vital enterprise in semio- tic research. As early as over a century ago, the American semiotician Charles Sanders Peirce laid down a solid foundation for this work by proposing his famous trichotomy of signs. Later scholars have been mostly applying Peirce’s theory to their own semiotic studies rather than challenging the inadequacies that exist therein, thus giving rise to a great number of confusions or even contradictions. The present article modifies Peirce’s theory from the perspective of sign emergence and evolution and emphasizes the importance of understanding sign transformations. Keywords: classification of signs, Peircean trichotomy, index, icon, symbol, sign emergence and evolution When scholars discuss the issue of sign classification, they tend to think of the American semiotician Charles Sanders Peirce, who is widely known for his trichotomous division of signs. For whatever reasons, Peirce takes a particular fancy to “3” and applies the number to many of the things he investigates. As can be seen in Figure 1, he breaks the entity of a sign into three essential elements (representamen, object, and interpretant) as opposed to two (signifier and signified), which is the case with Ferdinand de Saussure (1989: 67). The word “sign” at the top of Figure 1 ought to be interpreted in its narrow sense, referring to the form, vehicle or what Peirce himself calls the representa- men of a sign entity. The American then further analyses each of these elements into its own triple subcategories, resulting in his rather complicated if not cumbersome “three trichotomies.” To begin with, Peirce classifies a sign vehicle as qualisign, sinsign,orlegisign in accordance with its distinctive formal feature. The first subcategory under the *Corresponding author: Ersu Ding, Department of English, Lingnan University, Hong Kong, E-mail: [email protected] 166 Ersu Ding Figure 1: Peirce’s trichotomous division of signs. node of representamen includes positive material qualities that might be interpreted as meaningful; the second subcategory under the same node relates to the formal manifestation of a sign in a discursive context; the third subcate- gory under this node reveals underlying structures that govern various occur- rences of a sign. Peirce also analyses the interpretant of a sign into three subcategories: rheme, dicisign, and argument. Rheme, in the manner of qualisign, is a mere possibility to stand for an object and is therefore not related to truth; dicisign is an actual proposition that can be true or false but does not provide sufficient evidence; only argument, which is grounded in rules, is able to reveal truth about its object. Finally, Peirce divides signs into three subcategories in accordance with the different relationships between the object and its representamen: the first is the diagrammatic sign or icon, which exhibits a similarity or analogy to the subject of discourse; the second is the index, which like a pronoun demonstrative or relative, forces the attention to the particular object intended without describing it; the third is the general name or description which signifies its object by means of an associa- tions of ideas or habitual connection between the name and the character signified. (Peirce in Hoopes 1991: 181) Elsewhere, Peirce uses the term symbol for a sign whose interpretation depends on the habitual association of the name with its object. To summarize Peirce’s three trichotomies of signs discussed above, we can borrow a relevant diagram (Figure 2) made by Professor Michael Hoffmann (2001). As was mentioned earlier, Peirce’s system of sign classification is on the whole rather cumbersome and for that reason has been largely ignored by Rethinking the Peircean trichotomy 167 Figure 2: Peirce’s three trichotomies. semiotic scholars who are not Peirce specialists. The only exception to this state of limbo is his last trichotomy, which contains some very good insights and has had a huge influence on subsequent efforts at classifying signs. In fact, when scholars engage in sign classification today, they mostly adopt Peirce’s theore- tical framework of dividing signs into three categories of icon, index, and symbol. Two recent examples of this are Introduction to Semiotics (2004) by Huang Huaxin and Chen Zongming and Semiotics: Principles and Problems (2011) by Zhao Yiheng where the authors not only follow the Peircean trichotomous approach but also stick to his original sequence of discussing icon before index. What needs to be pointed out is that Peirce’s theorization on sign types is far from definitive and, in particular, he has made only limited contributions to our understanding of the mutual transformations between different kinds of signs. Our situation is made worse by the fact later scholars tend to overlook the emphasis on interpretation that is latent in Peirce’s semiotic theory. To rectify this problem, we need a new approach which takes into consideration the illuminating process of sign emergence and evolution. In terms of the evolutionary order, the use of indexes preceded other types of signs and played an important role in the lives of pre-literate people. It is not hard to imagine that our illiterate ancestors were able to predict rain if they saw a heavy concentration of dark cloud above their heads; nor is it ridiculous to expect them to be able to tell the gender of a woman who had two big breasts above her belly. In the former situation, the dark cloud serves as an indexical sign of rain whereas big breasts function as one for womanhood in the latter. The use of indexical signs is not, of course, the monopoly of the 168 Ersu Ding human race and occurs quite frequently in other animals, high and low. Corpse-eating vultures, for example, are able to tell whether a mammal is already dead by its lack of movement; wild tigers can also know the presence of other animals in the vicinity through theirparticularsmells.Oneinteresting experiment in this area was conducted by a former Soviet scientist I. P. Pavlov who,foranextendedperiodoftime,wouldringabelleachtimeadogwasfed. Gradually, his dog-subjects learned to associate food with the sound of his bell, which is proved by a measurable fact that even when a bell sound was not accompanied by food, his dogs still salivated. In other words, this parti- cular bell sound was treated by his dogs as an indexical sign for food. What these instances tell us is that Cassirer’s famous definition of man as an animal symbolicum (Cassirer 1956: 44) is not sufficiently accurate because other ani- mals also have the ability to use “symbols,” by which Cassirer means “signs.” Nevertheless, this definition confirms the importance of indexical signs that are common to animals of all kinds, including human beings. Even long after humans have developed spoken and written languages, indexical signs con- tinue to play an indispensable part in their lives as is evidenced by the following “little dramas” presented by Thomas Sebeok in his short introduc- tion to semiotics (Sebeok 2001: 25): – A radiologist spots a silhouette on a chest X-ray photograph of a patient and diagnoses lung cancer. – A meteorologist notes a rise in barometric pressure and delivers the next day’s forecast taking that change into account. – An anthropologist observes a complex of ceremonial exchanges practiced among members of a tribe; she draws analytical insights into the polity, economy, and social organization of the people she is studying. In other words, indexical signs and human languages co-exist in literate human societies, ancient or modern. Whatever circumstance they are in, indexical signs are born out of their users’ interpretations or judgments of the relationship between things or events. If event A frequently occurs prior to event B, one could interpret the former as an indexical sign of the latter as in the case of dark cloud leading to rain. One could also perform his/her deduction inversely in which case B becomes an indexical sign of A. For example, because fire often precedes smoke in time, if one sees smoke in a certain place, he/she could conclude from this that there was a fire in the same location earlier. Many semioticians view such a relationship as one of cause and effect, which is not exactly the case because a dark cloud does not always lead to rain and smoke is not necessarily caused by a preceding fire. An extreme example of the arbitrariness of indexicality comes from the dynastic Rethinking the Peircean trichotomy 169 histories of ancient China where, even though the emperor held supreme power, his courtiers could still exert some moral influence over him through a semiotic theory of “telepathy between humans and nature” (天人感应). According to such a theory, if an emperor misconducts himself, he would lose the Mandate of Heaven, resulting in huge and frequent natural disasters such as earthquakes, floods, and droughts (Fairbank and Goldman 2006: 48). For us moderns, there is no testable causal connection between the moral conduct of a person and the natural phenomena that transpire afterwards, but that did not prevent ancient Chinese scholars from interpreting the latter as indexical signs of the former. The story proves once again that indexical signs are the results of making arbitrary connections between things and events by sign users and not all connections are equally convincing in terms of general acceptability. If two events can be pulled together through their temporal contiguity as shown above, then two objects, two things, two entities, two situations, two geographical locations, etc., can also be connected through their being part of each other, giving rise to a different set of indexical signs otherwise known as metonymies.

THE TRICHOTOMY OF PROCESSES: A PHILOSOPHICAL BASIS FOR INFORMATION SYSTEMS George R. Widmeyer University of Michigan [email protected] Abstract The principle of trichotomy from the American philosopher Charles S. Peirce can be used to categorize processes into the triad of transactional, informational, and relational. The usefulness of these categories is explicated by a comparison with structuration theory and control theory, and elaborated with a consideration of democracy in a knowledge economy. These three example applications of the process triad show the generality of the conceptual categories and provide a natural way of bringing ideas from social and ethical theories into information systems design. Modeling the world and understanding business applications through the use of the Trichotomy of Processes should facilitate the development of more valuable information systems.

KANT ON RECOGNIZING OUR DUTIES AS GOD'S COMMANDS John E. Hare Kant both says that we should recognize our duties as God's commands, and objects to the theological version of heteronomy, 'which derives morality from a divine and supremely perfect will'. In this paper I discuss how these two views fit together, and in the process I develop a notion of autonomous submission to divine moral authority. I oppose the 'constitutive' view of autonomy proposed by J. B. Schneewind and Christine Korsgaard. I locate Kant's objection to theological heteronomy against the background of Crusius's divine command theory, and I compare Kant's views about divine authority and human political authority. 1.

Oxford: Oxford University Press. 2018. Reviewed by Stephen Palmquist, Department of Religion & Philosophy, Hong Kong Baptist University, Kowloon, Hong Kong, E-mail: [email protected] https://doi.org/10.1515/jtph-2020-0021 Notwithstanding its title, this book is not about the science called “logic”—at least, not insofar as “science of logic” refers to the rules, procedures, and guiding principles that constitute the laws of thought. While Huaping Lu-Adler often refers in passing to logical operations such as syllogisms, she never discusses their rules of operation. She does mention the law/principle of (non)contradiction eight times and that of identity once (p. 14); yet these all appear in quotes or side-comments. (She never mentions the law of excluded middle.) Similarly, she limits her treat- ment of potentially relevant post-Kantian developments in logic to a few brief glosses on Boole and Frege (pp. 3, 195–7), without referring to propositional logic, fuzzy logic, dialetheism, etc. However, this is all by design, so prepared readers need not be surprised by such omissions. Indeed, as the author announces in the Introduction and repeatedly reminds her readers, the book’s focus is on “the philosophy of logic” (pp. 3–4), not on the mechanics of how logical relations as such actually function. The Introduction acknowledges that historians of logic have typically either defined logic narrowly and therefore found nothing new—and thus little worth writing about—in Kant and other Enlightenment philosophers, or else they have followed Kant’s immediate predecessors by defining logic in a broader sense than we do nowadays and have therefore written voluminously on the views of “logic” advanced during this period, but in ways that relate very little to modern con- ceptions of logic.

This is a necessary initial step in conflict analysis. Here, our task is to approach conflicts where arms are used and the role this gives to conflict resolu- tion. Armed conflict is one category of the general phenomenon of social conflict. It has some distinct features. It normally grows out of non-armed conflict, in the sequences illustrated in Figure 3.3, but involves not just a shift in behaviour. It has other aspects associated with the three concepts of parties, incompatibility and action. First, there is a particular role for the state as soon as a conflict becomes armed. The reasons for this are explained in Section 4.2. There are also armed, as well as unarmed, non-state actors in many armed conflicts, and, for a fuller analy- sis, it is necessary to include them.

The entire dissertation is devoted to an extensive and in-depth analysis of this single paper in the form of commentary. All ¯fteen sections of the New List are examined. Rather than considering the textual genesis of the New List, or situating the work narrowly in the early philosophy of Peirce, as previous scholarship has done, this work pursues the genuine philosophical content of the New List, while paying attention to the later philosophy of Peirce as well. Immanuel Kant's Critique of Pure Reason is also taken into serious account, to which Peirce contrasted his new theory of categories. iii Table of Contents List of Figures . ix Acknowledgements . xi General Introduction 1 The Subject of the Dissertation . 1 Features of the Dissertation .

S Peirce was one ofthe founders ofPragmatism, alongside William James and John Dewey. This paper looks at Peirce's later work on his theory of signs, or semiotic. Peirce's semiotic is a broad one, including as signs things that other semioticians may reject. Peirce's semiotic includes a key division ofsigns into the three categories ofIcon, Index and Symbol. This trichotomy and the breadth ofPeirce's semiotic makes it well suited to, for example, a semiology of cinema. The basic structure ofthe sign in Peirce is also triadic, being a relation between sign-object-interpretant, and this brings us to a further appreciation of the sign as sign-action: a move from semiotic to semiosis. Peirce's approach to the philosophy of language goes beyond language to a theory of signs in general, and this 'semiotic' is deeply embedded within his broader systematic philosophical works. To understand it therefore, it is helpful to do two things: 1) to understand the breadth of Peirce's semiotic and 2) to differentiate it from other philosophical theories in the field.

  • A Biblical Study
    Trickotomy: A Biblical Study. ARTICLE V. TRICHOTOMY: A BIBLICAL STUDY. BY THE REV. S. H. KELLOGG, D. D., TORONTO, CANADA. CONSCIOUSNESS and revelation alike bear witness that, to speak in a general way, man is it being with a dual nature. I have a body; I am also conscious that I have a soul, of which my body is but the instrument. This is the true Ego; an immaterial essence, which thinks and feels and wills; but a material body has been assumed into organic union with it. Thus I am body and soul. In a like general way, in the account of creation as given in the book of Genesis, we read of two different elements as entering into the constitu­ tion of man; the one, material, a body, made "of the dust of the ground," the other, immaterial, the c~~1J ~rf~, "the breath of life (lives)," breathed into man by God, in the day that he created him. On this point, then, consciousness and Script­ ure bear consentient testimony; there is a dichotomy in the nature of man. But this being granted, the question still re­ mains, whether a further analysis is possible. Philosophy, indeed, whether right or wrong, long ago insisted that a further distinction must be made in the immaterial part of man, as containing in the unity of the one person, first, the yvx7f, or "animal soul," and secondly, the JlO~, or "intel­ ligence." Whether these names were well chosen or not, or whether there was any sufficient ground for the distinction, we do not yet inquire.

  • C:\Essays Edited for the Riddleblog\Trichotomy.Wpd
    Trichotomy: Beachhead For Gnostic Influences By Kim Riddlebarger Originally published in ModernReformation (July/August 1995) and edited for publication on the Riddleblog ______________________________________________________________ One of the most difficult problems any theological tradition faces is that there are often times fundamental differences at critical points between the “official doctrine” affirmed by the divines and academics of that tradition, and those doctrines actually believed and practiced on a popular level by the rank and file. There is, perhaps, no greater illustration of this than the popular notion of trichotomy. Rejected by virtually all major theologians in all streams of the Christian tradition as a speculative Greek philosophical notion rather than a biblical conception, trichotomy is very likely the reigning notion of human nature in American evangelical circles today. With few exceptions, the Christian church has affirmed, with one voice, that human nature is bipartite. As men and women, we are necessarily a body–the physical aspect of our nature–and we are also a soul-spirit–the immaterial aspect described in the Bible as either soul or spirit. These two are united together as one person in a psychosomatic unity. This is simply known as dichotomy. Trichotomists, however, contend that human nature is tripartite, that is, as men and women we are body, soul and spirit. But while the theologians of evangelicalism, following the historic precedence, overwhelmingly reject the notion of trichotomy, the popular teaching and literature of evangelicalism abounds with trichotomistic views of human nature in one form or another. It is also no accident that the Gnostic impulse, now so rampant in the quest for spirituality, finds a ready-made beachhead into evangelical circles through the trichotomist view of human nature.

    Higher Dimensional Trichotomy Conjectures in Model Theory by Benjamin Castle A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Mathematics in the Graduate Division of the University of California, Berkeley Committee in charge: Professor Thomas Scanlon, Chair Associate Professor Pierre Simon Associate Professor Adityanand Guntuboyina Spring 2021 Higher Dimensional Trichotomy Conjectures in Model Theory Copyright 2021 by Benjamin Castle 1 Abstract Higher Dimensional Trichotomy Conjectures in Model Theory by Benjamin Castle Doctor of Philosophy in Mathematics University of California, Berkeley Professor Thomas Scanlon, Chair In this thesis we study the Restricted Trichotomy Conjectures for algebraically closed and o-minimal fields. These conjectures predict a classification of all sufficiently complex, that is, non-locally modular, strongly minimal structures which can be interpreted from such fields. Such problems have been historically divided into `lower dimensional' and `higher dimen- sional' cases; this thesis is devoted to a number of partial results in the higher dimensional cases. In particular, in ACF0 and over o-minimal fields, we prove that all higher dimensional strongly minimal structures whose definable sets satisfy certain geometric restrictions are locally modular. We also make progress toward verifying these geometric restrictions in any counterexample. Finally, in the last chapter we give a full proof of local modularity for strongly minimal expansions of higher dimensional groups in ACF0. i To Katrina and Justin ii Contents Contents ii 1 Introduction 1 1.1 Historical Background . 1 1.2 The Challenge of Working in Higher Dimensions . 3 1.3 Outline of Results . 5 2 Preliminaries on Strongly Minimal Sets 7 2.1 Strong Minimality and Dimension .
