    Extractions: OCT Charles Peirce's contributions to logical theory are numerous and profound. His work on relations building on ideas of De Morgan influenced Schroder, and through Schroder, Peano, Russell, Lowenheim and much of contemporary logical theory. Although Frege anticipated much of Peirce's work on relations and quantification theory, and to some extent developed it to a greater extent, Frege's work remained out of the mainstream until the twentieth century. Thus it is plausible that Peirce's influence on the development of logic has been of the same order as Frege's. Further discussion of Peirce's influence can be found in Dipert (1995). In contrast to Frege's highly systematic and thoroughly developed work in logic, Peirce's work remains fragmentary and extensive, rich with profound ideas but most of them left in a rough and incomplete form. Three of the Peirce's contributions to logic that are not as well-known as others are described below: In three unnumbered pages from his unpublished notes written before 1910, Peirce developed what amounts to a semantics for three-valued logic. This is at least ten years before Emil Post's dissertation, which is usually cited as the origin of three-valued logic. A good source of information about these three pages is Fisch and Turquette (1966), which also includes reproductions of the three pages from Peirce's notes.

    Extractions: Charles S Peirce was the son of Benjamin Peirce and studied at Harvard and worked for many years on the Coast and Geodetic Survey. He worked on geodesy but became interested in conformal map projections where he invented a quincuncial map projection using elliptic functions He was also interested in the Four Colour Problem and problems of knots and linkages studied by Kempe . He then extended his father's work on associative algebras and worked on mathematical logic and set theory. Except for courses on logic he gave at Johns Hopkins University, between 1879 and 1884, he never held an academic post. T S Fiske , writing about the New York Mathematical Society (before it became the American Mathematical Society) in [23], describes Charles Peirce:- Conspicuous among those who in the early nineties attended the monthly meetings ... was the famous logician, Charles S Peirce. His dramatic manner, his reckless disregard of accuracy in what he termed 'unimportant details', his clever newspaper articles describing the meetings of our young Society interested and amused us all. ... He was always hard up, living partly on what he could borrow from friends, and partly on what he got from odd jobs such as writing book reviews ... He was equally brilliant, whether under the influence of liquor or otherwise, and his company was prized by the various organisations to which he belonged; and he was never dropped from any of them even though he was unable to pay his dues. He infuriated Charlotte Angas

    Short description of semiotics. Includes information about the ideas of Ferdinand de Saussure and charles sanders peirce.  
    http://atheism.about.com/library/glossary/aesthetics/bldef_semiotics.htm
    
    Extractions: Semiotics is the study of signs and signifying practices, is largely the creation of the Swiss linguist Ferdinand de Saussure and the American pragmatist Charles Sanders Peirce. Independently, they worked to better understand how certain structures were able to produce meaning rather than work on the traditional matter of meaning itself. Saussure's work on semiotics is better known, and he argued that there was no inherent or necessary relationship between that which carries the meaning (the signifier, usually a word or symbol) and the actual meaning which is carried (the signified). For example, the word "car" is not actually a car - the meaning of car could be carried by any random string of letters. It just so happens that, in English, that meaning is carried by the letter c-a-r. Peirce's ideas about semiotics distinguished between three types of signs: icon, index and symbol. Whether a sign belongs in one category or another is dependent upon the

Peirce Edition Project Charles Sanders Peirce (1839-1914) is unique in American intellectual history and is of seminal importance for modern thought. He was a tireless and brilliant thinker whose extensive writings have received international attention for over a century. Remarkably, however, much of what Peirce wrote remains in manuscript form, unpublished and in significant disarray. There has never been a comprehensive edition of Peirce's writings organized chronologically and edited according to current scholarly practices. The Peirce Edition Project was established in 1976 and has been part of IUPUI's School of Liberal Arts since 1983. Its mission is to organize and date the manuscripts and to produce an approved scholarly edition of Peirce's writings. This work is assisted by an internationally recognized team of advisors and contributors. Five volumes (of a projected thirty) have been published by Indiana University Press and plans are underway for a parallel electronic edition.

    Extractions: Charles Sanders Peirce, pronounced "purse" (1839-1914), the founder of pragmatism and a pioneering theorist of Semiotics , was one of America's most important and most original philosophers. His scope and range are perhaps wider than that of any philosopher since Gottfried Wilhelm Leibniz. He made fundamental contributions to probability theory, symbolic logic, the philosophy of science, mathematics, and semiotics, while publishing numerous papers on astronomy, physics, chemistry, and scientific method. Peirce generally described himself as an experimentalist and a "logician," a term that expanded in scope from his earliest papers to encompass virtually the whole enterprise of organized thought and inquiry. Despite being frequently recommended for university appointments, Peirce served only as a part-time lecturer in logic at Johns Hopkins University from 1879 to 1884 and for three years as a special lecturer in the philosophy of science at Harvard. Although he was a prolific writer, only two books appeared during his lifetime: Photometric Researches (1878), which established him as one of the leading astrophysicists of his day, and

Except for occasional lectures he renounced the regimen of academic life and was in government service with the Geodetic Survey for many years. Regarding logic as the beginning of all philosophical study, Peirce felt that the meaning of an idea was to be found in an examination of the consequences to which the idea would lead. This principle was published in 1878 in Popular Science Monthly, using the term pragmatism , which was later employed, with acknowledgment, by his friend William James A major thinker in a number of fields, Peirce is also recognized as the originator of the modern form of semiotics and the first American experimental psychologist. His influence is clearly seen in the works of Josiah

    Extractions: Virtuality, Communication, and Community Thought is what it is only by virtue of its addressing a future thought which is in its value as thought identical with it, though more developed.  In this way, the existence of thought now depends on what is to be hereafter; so that it has only a potential existence, dependent on the future thought of the community. No present actual thought (which is [in itself] a mere feeling) has any meaning, any intellectual value; for this lies not in what is actually thought, but in what this thought may be connected with in representation by subsequent thoughts, so that the meaning of a thought is altogether something virtual.

    Extractions: A fixação da crença Popular Science Monthly 12 (November 1877), pp. 1-15) (versão inglesa) Charles Sanders Peirce (tradução de Anabela Gradim Alves, Universidade da Beira Interior) I Poucas pessoas se dão ao trabalho de estudar lógica, porque toda a gente se concebe a si própria como sendo já suficientemente versado na arte de raciocinar. Mas eu constato que essa satisfação se limita à sua própria capacidade de raciocinar, e não se estende à dos outros homens. Entramos na plena posse do nosso poder de retirar inferências como a última das nossas faculdades, pois não é tanto um dom natural, mas uma longa e difícil arte. A história da sua prática daria um esplêndido assunto para um livro. Os escolásticos medievais, seguindo os romanos, faziam da lógica, depois da gramática, o primeiro dos estudos de um rapaz, e apresentavam-no como sendo muito fácil. Assim era, tal como o entendiam. O seu princípio fundamental, segundo eles, era que todo o conhecimento repousa ou na autoridade ou na razão; mas o que quer que seja deduzido pela razão depende em última análise de uma premissa derivada da autoridade. Deste modo, assim que um rapaz era perfeito no procedimento silogístico, acreditava-se que o seu conjunto de ferramentas intelectuais estava completo. Os primeiros cientistas, Copérnico, Tycho Brahé, Kepler, Galileu e Gilbert, tinham métodos mais semelhantes aos dos seus modernos confrades. Kepler empreendeu desenhar uma curva através da órbita de Marte; e o seu maior serviço à ciência foi imprimir na mente dos homens que isto era o que deveria ser feito se desejavam melhorar a astronomia; e que não deveriam contentar-se com inquirir se um sistema de epiciclos era melhor que outro, mas que deveriam reflectir sobre os números e descobrir o que a curva, na verdade, era. Ele conseguiu isto pela sua incomparável energia e coragem, tropeçando às cegas da forma mais inconcebível (para nós), de uma hipótese irracional para outra, até que, depois de tentar vinte e duas destas tropeçou, por mera exaustão da sua invenção, sobre a órbita que uma mente bem apetrechada com as armas da lógica moderna teria tentado quase à partida.

40. Charles Sanders Peirce, The Fixation Of Belief
    charles sanders peirce. Few persons care to study logic, because everybody conceiveshimself to be proficient enough in the art of reasoning already.  
    http://bocc.ubi.pt/pag/peirce-charles-fixation-belief.html
    
    Extractions: The object of reasoning is to find out, from the consideration of what we already know, something else which we do not know. Consequently, reasoning is good if it be such as to give a true conclusion from true premises, and not otherwise. Thus, the question of its validity is purely one of fact and not of thinking. A being the premises and B the conclusion, the question is, whether these facts are really so related that if A is B is. If so, the inference is valid; if not, not. It is not in the least the question whether, when the premisses are accepted by the mind, we feel an impulse to accept the conclusion also. It is true that we do generally reason correctly by nature. But that is an accident; the true conclusion would remain true if we had no impulse to accept it; and the false one would remain false, though we could not resist the tendency to believe in it. A book might be written to signalize all the most important of these guiding principles of reasoning. It would probably be, we must confess, of no service to a person whose thought is directed wholly to practical subjects, and whose activity moves along thoroughly-beaten paths. The problems which present themselves to such a mind are matters of routine which he has learned once for all to handle in learning his business. But let a man venture into an unfamiliar field, or where his results are not continually checked by experience, and all history shows that the most masculine intellect will ofttimes lose his orientation and waste his efforts in directions (W3.246) which bring him no nearer to his goal, or even carry him entirely astray. He is like a ship in the open sea, with no one on board who understands the rules of navigation. And in such a case some general study of the guiding principles of reasoning would be sure to be found useful.
