Wittgenstein in Exile
Wittgenstein in Exile “My thoughts are one hundred per cent Hebraic.” -Wittgenstein to Drury, 19491 Wittgenstein was born in 1889 into one of the richest families in Central Europe. He lived and learned at home, in Vienna, until 1903, when he was 14. We have no record of his thoughts about the turn of the last century, but it is unlikely that it seemed very significant to him. The Viennese of the time had little inclination to consider the possibilities of change, and the over-ripe era in which Wittgenstein grew up did not really end until Austria-Hungary’s defeat, in World War I, and subsequent dismantling. But the family in which Wittgenstein grew up apparently felt that European culture had already come to an end in the 1840’s. And Wittgenstein himself felt he belonged to an era that had vanished with the death of the composer Robert Schumann (1810-1856).2 Somewhere in the middle of the Nineteenth Century there was an important change into the contemporary era, of which Wittgenstein did not feel a part. Wittgenstein’s understanding of history, and his consequent self-understanding in relation to his times, was deeply influenced by Oswald Spengler, who in 1918 published The Decline of the West [Der Untergang des Abenlandes]. This book, expanded to a second volume in 1922, and revised in 1923, became a best-seller in post-war Europe. Wittgenstein made numerous references to it in 1930-1931, and acknowledged Spengler as one of his ten noteworthy influences.3 According to Spengler, cultures grow, flower, and deteriorate naturally, according to their own internal form, much as a human being does. -

John P. Burgess Department of Philosophy Princeton University Princeton, NJ 08544-1006, USA [email protected] LOGIC & PHILOSOPHICAL METHODOLOGY Introduction For present purposes “logic” will be understood to mean the subject whose development is described in Kneale & Kneale [1961] and of which a concise history is given in Scholz [1961]. As the terminological discussion at the beginning of the latter reference makes clear, this subject has at different times been known by different names, “analytics” and “organon” and “dialectic”, while inversely the name “logic” has at different times been applied much more broadly and loosely than it will be here. At certain times and in certain places — perhaps especially in Germany from the days of Kant through the days of Hegel — the label has come to be used so very broadly and loosely as to threaten to take in nearly the whole of metaphysics and epistemology. Logic in our sense has often been distinguished from “logic” in other, sometimes unmanageably broad and loose, senses by adding the adjectives “formal” or “deductive”. The scope of the art and science of logic, once one gets beyond elementary logic of the kind covered in introductory textbooks, is indicated by two other standard references, the Handbooks of mathematical and philosophical logic, Barwise [1977] and Gabbay & Guenthner [1983-89], though the latter includes also parts that are identified as applications of logic rather than logic proper. The term “philosophical logic” as currently used, for instance, in the Journal of Philosophical Logic, is a near-synonym for “nonclassical logic”. There is an older use of the term as a near-synonym for “philosophy of language”. -
Wittgenstein, Ludwig (1889-1951) by Craig Kaczorowski
Wittgenstein, Ludwig (1889-1951) by Craig Kaczorowski Encyclopedia Copyright © 2015, glbtq, Inc. Entry Copyright © 2004, glbtq, inc. Reprinted from http://www.glbtq.com The Austrian-British philosopher Ludwig Wittgenstein is considered one of the most significant thinkers of the twentieth century, especially for his valuable contributions within the field of Linguistic Philosophy. His major works on language and linguistics include Tractatus Logico-Philosophicus (1922), and Philosophical Investigations (1953), which was published posthumously. Early Life and Education Born Ludwig Josef Johann Wittgenstein in Vienna on April 26, 1889, he was the youngest of eight children raised in a wealthy and cultured Jewish family. Initially educated privately at home, at the age of 14 he began attending a school in Linz, Austria that specialized in mathematics and natural science. In 1906, he went to Berlin to study mechanical engineering and two years later registered at the University of Manchester in England to study for his doctorate in engineering. Over time, however, Wittgenstein developed a greater interest in mathematics and mathematical logic, and he transferred to Trinity College, University of Cambridge, where he took courses from 1912 to 1913 given by the distinguished philosopher and mathematician Bertrand Russell. In November 1912, on the recommendation of fellow student John Maynard Keynes, Wittgenstein was elected to the elite Cambridge society known as the Apostles, which at that time had an aura of homoeroticism. This homoerotic atmosphere made Wittgenstein uncomfortable, however, and he stopped attending meetings. Finding Cambridge a less than ideal place to work, since he felt that his fellow academics lacked depth, Wittgenstein went to Skjolden in Norway and continued his mathematical and philosophical investigations in seclusion. -

ON THE RELATION OF INFORMAL TO FORMAL LOGIC Dale Jacquette Department of Philosophy The Pennsylvania State University ©1998, Dale Jacquette Abstract: The distinction between formal and informal logic is clarified as a prelude to considering their ideal relation. Aristotle's syllogistic describes forms of valid inference, and is in that sense a formal logic. Yet the square of opposition and rules of middle term distribution of positive or negative propositions in an argument's premises and conclusion are standardly received as devices of so- called informal logic and critical reasoning. I propose a more exact criterion for distinguishing between formal and informal logic, and then defend a model for fruitful interaction between informal and formal methods of investigating and critically assessing the logic of arguments. *** 1. A Strange Dichotomy In the history of logic a division between formal and informal methods has emerged. -
Advice on the Logic of Argument†
Revista del Instituto de Filosofía, Universidad de Valparaíso, Año 1, N° 1. Junio 2013. Pags. 7 – 34 Advice on the Logic of Argument† John Woods Resumen Desde su creación moderna a principios de la década de los 70, la lógica informal ha puesto un especial énfasis en el análisis de las falacias y los esquemas de diálogo argumentativo. Desarrollos simultáneos en los círculos que se ocupan de los actos de comunicación de habla exhiben una concentración en el carácter dialéctico de la discusión. PALABRAS CLAVE: Lógica informal, argumento, diálogos Abstract Since its modern inception in the early 1970s, informal logic has placed a special emphasis on the analysis of fallacies and argumentative dialogue schemes. Concurrent developments in speech communication circles exhibit a like concentration on the dialectical character of argument. KEYWORDS: Informal logic, argument, dialogues “But the old connection [of logic] with philosophy is closest to my heart right now . I hope that logic will have another chance in its mother area.” Johan van Benthem “On [the] traditional view of the subject, the phrase ‘formal logic’ is pleonasm and ‘informal logic’ oxymoron.” John Burgess 1.

Contemporary DOI: https://doi.org/10.22329/il.v39i1.5080 scholarship, by contrast, treats conductive argument predominantly on a product view. Not only did Wellman’s reasons for a dialectical view thus fall See table of contents into disregard; a product-treatment of conduction also flouts the standard semantics of ‘argument’. Attempting to resolve these difficulties, our paper traces Wellman’s preference for a dialectical view to the role of defeasible Publisher(s) warrants. These act as stand-ins for (parts of) value hierarchies that arguers of normal suasory inclination find acceptable. We also improve on extant ways of Informal Logic diagramming conduction and distinguish two of its structural variants.

A Modest Defense of Fallacy Theory SCOTT F. AIKIN Philosophy Vanderbilt University 111 Furman Hall Nashville, TN 37240 USA [email protected] Abstract: Fallacy theory has three significant challenges to it: the generality, scope, and negativity problems. To the generality problem, the connection between general types of bad arguments and tokens is a matter of refining the use of the vocabulary. To the scope problem, the breadth of fallacy’s instances is cause for development. To the negativity problem, fallacy theory must be coordinated with a program of adversariality-management. Keywords: fallacy theory; minimal adversariality 1. Introduction Fallacy theory is the convergence of three broad programs in the study of argument. First is the first-order research program of defining fallacy, taxonomizing and finding new types. -

Informal Logic 25 Years Later the First International Symposium On
Informal logic 25 years later The First International Symposium on Informal Logic, held on this campus on June 26 to 28, 1978, was a rise to self-consciousness of a newly distinguished sub-field of philosophy. This sub-field differentiated itself through the belief of some philosophy instructors in North American colleges and universities that the traditional introductory logic course was not much good at helping to improve students’ abilities to deal with the arguments they encountered in everyday life and in academic contexts. Courses centred on formal systems–whether the systems of categorical syllogistic and propositional logic done by truth tables or the more comprehensive and up-to-date system of first-order logic–had no relevance to the highly charged debates of the late 1960s and early 1970s about such issues as American military action in Vietnam and the position of women in society. In response, a new kind of textbook began to emerge, often focussed on the informal fallacies, which had been a neglected backwater of the traditional introductory logic course. A pioneer among these textbooks was Howard Kahane’s Logic and Contemporary Rhetoric, subtitled “The Use of Reason in Everyday Life”, the first edition of which was published in 1971 (Kahane 1971); it is now in its ninth edition. Kahane, who gave a paper at the First International Symposium on Informal Logic entitled “The Nature and Classification of Fallacies” (Kahane 1980), died two years ago, on May 2, 2001.

Wittgenstein's Philosophical Development: Phenomenology, Grammar, Method, and the Anthropological View
Nordic Wittgenstein Review 5 (2) 2016 INVITED PAPER Juliet Floyd jfloyd @ bu.edu Chains of Life: Turing, Lebensform, and the Emergence of Wittgenstein’s Later Style Abstract This essay accounts for the notion of Lebensform by assigning it a logical role in Wittgenstein’s later philosophy. Wittgenstein’s additions of the notion to his manuscripts of the PI occurred during the initial drafting of the book 1936-7, after he abandoned his effort to revise The Brown Book. It is argued that this constituted a substantive step forward in his attitude toward the notion of simplicity as it figures within the notion of logical analysis. Next, a reconstruction of his later remarks on Lebensformen is offered which factors in his reading of Alan Turing’s “On computable numbers, with an application to the Entscheidungsproblem“ (1936/7), as well as his discussions with Turing 1937-1939. An interpretation of the five occurrences of Lebensform in the PI is then given in terms of a logical “regression” to Lebensform as a fundamental notion. This regression characterizes Wittgenstein’s mature answer to the question, “What is the nature of the logical?” 1. Introduction Lebensform is an important gauge of the development of Wittgenstein’s thought. It represents, from a regressive point of view, the place he finally chased down to. In foundational matters such as these, it is often the simplest, naïve perspective that comes last in a thinker’s (or a tradition’s) evolution, the working through 7 Juliet Floyd CC-BY of how to get back home to the primordial basis, the extraction of fundamentals from a jungle of technical accretions. -

This “The purpose of a proof is to understand, not verify”-- Arnold Ross. project was mentored by Dr. Catherine n mathematics, a proof is a demonstration that, given certain axioms, some Womack. statement of interest is necessarily true. Proofs employ logic but usually include some amount of natural language which of course admits some ambiguity. In fact, the vast majority of proofs in written mathematics can be considered as applications of informal logic. The distinction has led to much Iexamination of current and historical mathematical practice, quasi-empiricism in mathematics. One of the concerns with the philosophy of mathematics is the role of language and logic in proofs, and mathematics as a language. Regardless of one’s attitude to formalism, the result that is proved to be true is a theorem; in a completely formal proof it would be the final word, and the complete proof shows how it follows from the axioms alone.
