Language, Communication, and Representation in the Semiotic of John Poinsot

LANGUAGE, COMMUNICATION, AND REPRESENTATION IN THE SEMIOTIC OF JOHN POINSOT1 }AMES BERNARD MURPHY Dartmouth College Hanover, New Hampshire 1) Language and the Semiotic of John Poinsot HE SEMIOTIC of John Poinsot is to the study of gns what physics is to the study of nature. Physics is oth the most fundamental and the most general science of nature. All natural processes, from the motion of planets to the division of cells, are governed by, but not only by, laws of physics. Similarly, the semiotic of John Poinsot (traditionally known by his Dominican name, John of St. Thomas) is the most fundamental and general science of signs. The actions of all signs -from natural signs such as footprints and symptoms of disease , to signs of communication, such as logical operators and linguistic signs, to signs in cognition, such as concepts and percepts -are governed by, but not only by, the fundamental relational logic of semiosis set forth in his Ars Logica [1632]. If C. S. Peirce can be said to give us a chemistry of sixty-six signcompounds , John Poinsot, suitably revised, gives us the basic physical laws of motion that bring sign, object, and mind into relation.2 i The author would like to acknowledge gratefully the fellowships received from the American Council of Learned Societies and from Dartmouth College supporting the research of this article. I also wish to acknowledge the help of my research assistant, Daniel Glazer, in hunting down many essential books and articles. John Deely assisted by correcting my discussion of some of the finer points of Poinsot's theory as well as by providing many other helpful suggestions for revision. 2 The first modern author to point this out was Jacques Maritain, especially in "Signe et symbole," Revue Thomiste 44 (April 1938), pp. 299-300 and 569 570 JAMES BERNARD MURPHY What I wish to explore here is the question: To what extent does the semiotic of John Poinsot account for the meaning of linguistic signs ? In one sense, we cannot expect such a fundamental and general theory of the action of signs to tell us much about language. Language is a surpassingly complex and, in many ways, a unique sign-system. Expecting a general theory of signs to capture the meaning of the linguistic sign is like expecting physics to explain reproductive biology. In another sense, though, we ought to expect his semiotic to illuminate that preeminent system of signs, human language. For in addition to "Le Langage et la theorie du signe," Anne.:re au chapitre II of Quatre essais sur !'esprit dans sa condition charnelle (Nouvelle edition revue et augmentee; Paris: Alsatia, 1956), pp. 113-124. This latter essay appears in a modestly amplified English version, " Language and the Theory of Sign," from Language : An Enquiry into Its Meaning and Function, edited by Ruth Nanda Anshen (New York: Harper and Brothers, 1957), pp. 86-101; and, fully annotated in relation to Poinsot's Tractatus de Signis, it has been reprinted in Frontiers in Semiotics, edited by John Deely, Brooke Williams, and Felicia Kruse (Bloomington, IN: Indiana University Press, 1986), pp. 51-62. Following Maritain, a number of authors have attempted to apply Poinsot's semiotic to contemporary debates. I note the principal ones in chronological order: John A. Oesterle, " Another Approach to the Problem of Meaning," The Thomist 7 (1944), pp. 233-263; John Wild, "An Introduction to the Phenomenology of Signs," Philosophy and Phenomenological Research 8 (December 1947), pp. 217-244; Henry B. Veatch, Intentional Logic (New Haven: Yale University Press, 1952). Poinsot's Treatise on Signs was originally published in 1632 as a small part of volume 2 in the original five volumes (Alcala, Spain: 1631-1635) of his philosophical writings. These five volumes have been published as three volumes under the title Cursus Philosophicus Thomisticus in the modern edition by Beatus Reiser (Turin: Marietti, 1930, 1933, 1937). The first independent presentation of Poinsot's complete Tractatus de Signis was prepared by John Deely in consultation with Ralph A. Powell and published in bilingual critical edition (Berkeley: University of California Press, 1985). Since the publication of this edition of the Tractatus, two major critiques and reconstructions of Poinsot's analysis...
