Harper, Robert This is in contrast with the usual views in philosophical skepticism , where logic directs skeptical enquiry to doubt received wisdoms, as in the work of Sextus Empiricus. Wellesley, Mass. The approach assumes that the meaning of the various parts of the propositions are given by the possible ways we can give a recursively specified group of interpretation functions from them to some predefined domain of discourse : an interpretation of first-order predicate logic is given by a mapping from terms to a universe of individuals , and a mapping from propositions to the truth values "true" and "false". Case arguing against Sigwart's and Brentano's modern analysis of the universal proposition. This ancient motivation is still alive, although it no longer takes centre stage in the picture of logic; typically dialectical logic forms the heart of a course in critical thinking , a compulsory course at many universities. Cambridge, MA. More Info. Augustine's Press. The concrete terms 'man', 'mortal', etc. Frege's original system of predicate logic was second-order, rather than first-order. About this Course 70, recent views. Such games can provide a formal game semantics for many logics. Introduction to Logic. Examples of formal logic include 1 traditional syllogistic logic a. Whilst Aristotelian syllogistic logic specifies a small number of forms that the relevant part of the involved judgements may take, predicate logic allows sentences to be analysed into subject and argument in several additional ways—allowing predicate logic to solve the problem of multiple generality that had perplexed medieval logicians. This was partly because of the resistance to reducing the categorical judgment 'every s is p' to the so-called hypothetical judgment 'if anything is s, it is p'. Barwise, J. More broadly, logic is the analysis and appraisal of arguments. Philosophical logic has a much greater concern with the connection between natural language and logic.

Historically, logic has been studied in philosophy since ancient times and mathematics since the midth century. During the High Middle Ages , logic became a main focus of philosophers, who would engage in critical logical analyses of philosophical arguments, often using variations of the methodology of scholasticism. The Organon was Aristotle 's body of work on logic, with the Prior Analytics constituting the first explicit work in formal logic, introducing the syllogistic. The study of inference and truth. Redwood City, Calif. Introduction to Elementary Mathematical Logic. Informal Logic. Closely related to questions arising from the paradoxes of implication comes the suggestion that logic ought to tolerate inconsistency. The analytical generality of predicate logic allowed the formalization of mathematics, drove the investigation of set theory , and allowed the development of Alfred Tarski 's approach to model theory. In the summer of , John McCarthy , Marvin Minsky , Claude Shannon and Nathan Rochester organized a conference on the subject of what they called " artificial intelligence " a term coined by McCarthy for the occasion. Many terms in logic, for this reason, are in Latin. Thus, for example, the expression "all Ps are Qs" shows the logical form common to the sentences "all men are mortals", "all cats are carnivores", "all Greeks are philosophers", and so on. In many definitions of logic, logical consequence and inference with purely formal content are the same. Introduction to Logic Writer The form of an argument is displayed by representing its sentences in the formal grammar and symbolism of a logical language to make its content usable in formal inference. Ask a Question What would you like to know about this product? This section may be confusing or unclear to readers. More broadly, logic is the analysis and appraisal of arguments. Antoine Arnauld in the Port Royal-Logic , [18] [19] says that after conceiving things by our ideas, we compare these ideas, and, finding that some belong together and some do not, we unite or separate them. In Mckeon, Richard ed. A logical system is essentially a way of mechanically listing all the logical truths of some part of logic by means of the application of recursive rules—i. Main articles: Computational logic and Logic in computer science. Here we are going to be concerned with propositional logic and predicate logic, which are fundamental to all types of logic. Retrieved 10 May The philosophical vein of various kinds of skepticism contains many kinds of doubt and rejection of the various bases on which logic rests, such as the idea of logical form, correct inference, or meaning, typically leading to the conclusion that there are no logical truths. It is uniquely medieval, though it has its origins in Aristotle's Topica and Boethius ' De Syllogismis hypotheticis. Logic is commonly taught by university philosophy, sociology, advertising and literature departments, often as a compulsory discipline. More abstractly, we might say that modality affects the circumstances in which we take an assertion to be satisfied. Deductive reasoning concerns the logical consequence of given premises and is the form of reasoning most closely connected to logic. In the third part we have shown how the study of the so-called 'restrictive conditions for universals' in Navya-Nyaya logic anticipated some of the developments of modern set theory. These include inductive reasoning , which covers forms of inference that move from collections of particular judgements to universal judgements, and abductive reasoning , [ii] which is a form of inference that goes from observation to a hypothesis that accounts for the reliable data observation and seeks to explain relevant evidence. Upon this first, and in one sense this sole, rule of reason, that in order to learn you must desire to learn, and in so desiring not be satisfied with what you already incline to capably think, there follows one corollary which itself deserves to be inscribed upon every wall of the city of philosophy: Do not block the way of inquiry.

Since logic-based approaches lay at the core of symbolic AI, summarizing their state of the art is of paramount importance now more than ever, in order to identify trends, benefits, key features, gaps, and limitations of the techniques proposed so far, as well as to identify promising research perspectives. Along this line, this paper provides an overview of logic-based approaches and technologies by sketching their evolution and pointing out their main application areas. Future perspectives for exploitation of logic-based technologies are discussed as well, in order to identify those research fields that deserve more attention, considering the areas that already exploit logic-based approaches as well as those that are more likely to adopt logic-based approaches in the future.

  • Toward a Logic of Everyday Reasoning
    Toward a Logic of Everyday Reasoning Pei Wang Abstract: Logic should return its focus to valid reasoning in real-world situations. Since classical logic only covers valid reasoning in a highly idealized situation, there is a demand for a new logic for everyday reasoning that is based on more realistic assumptions, while still keeps the general, formal, and normative nature of logic. NAL (Non-Axiomatic Logic) is built for this purpose, which is based on the assumption that the reasoner has insufficient knowledge and resources with respect to the reasoning tasks to be carried out. In this situation, the notion of validity has to be re-established, and the grammar rules and inference rules of the logic need to be designed accordingly. Consequently, NAL has features very different from classical logic and other non-classical logics, and it provides a coherent solution to many problems in logic, artificial intelligence, and cognitive science. Keyword: non-classical logic, uncertainty, openness, relevance, validity 1 Logic and Everyday Reasoning 1.1 The historical changes of logic In a broad sense, the study of logic is concerned with the principles and forms of valid reasoning, inference, and argument in various situations. The first dominating paradigm in logic is Aristotle’s Syllogistic [Aristotle, 1882], now usually referred to as traditional logic. This study was carried by philosophers and logicians including Descartes, Locke, Leibniz, Kant, Boole, Peirce, Mill, and many others [Bochenski,´ 1970, Haack, 1978, Kneale and Kneale, 1962]. In this tra- dition, the focus of the study is to identify and to specify the forms of valid reasoning Pei Wang Department of Computer and Information Sciences, Temple University, Philadelphia, USA e-mail: [email protected] 1 2 Pei Wang in general, that is, the rules of logic should be applicable to all domains and situa- tions where reasoning happens, as “laws of thought”.

  • Formalizing Common Sense Reasoning for Scalable Inconsistency-Robust Information Integration Using Direct Logictm Reasoning and the Actor Model
    Formalizing common sense reasoning for scalable inconsistency-robust information integration using Direct LogicTM Reasoning and the Actor Model Carl Hewitt. http://carlhewitt.info This paper is dedicated to Alonzo Church, Stanisław Jaśkowski, John McCarthy and Ludwig Wittgenstein. ABSTRACT People use common sense in their interactions with large software systems. This common sense needs to be formalized so that it can be used by computer systems. Unfortunately, previous formalizations have been inadequate. For example, because contemporary large software systems are pervasively inconsistent, it is not safe to reason about them using classical logic. Our goal is to develop a standard foundation for reasoning in large-scale Internet applications (including sense making for natural language) by addressing the following issues: inconsistency robustness, classical contrapositive inference bug, and direct argumentation. Inconsistency Robust Direct Logic is a minimal fix to Classical Logic without the rule of Classical Proof by Contradiction [i.e., (Ψ├ (¬))├¬Ψ], the addition of which transforms Inconsistency Robust Direct Logic into Classical Logic. Inconsistency Robust Direct Logic makes the following contributions over previous work: Direct Inference Direct Argumentation (argumentation directly expressed) Inconsistency-robust Natural Deduction that doesn’t require artifices such as indices (labels) on propositions or restrictions on reiteration Intuitive inferences hold including the following: . Propositional equivalences (except absorption) including Double Negation and De Morgan . -Elimination (Disjunctive Syllogism), i.e., ¬Φ, (ΦΨ)├T Ψ . Reasoning by disjunctive cases, i.e., (), (├T ), (├T Ω)├T Ω . Contrapositive for implication i.e., Ψ⇒ if and only if ¬⇒¬Ψ . Soundness, i.e., ├T ((├T) ⇒ ) . Inconsistency Robust Proof by Contradiction, i.e., ├T (Ψ⇒ (¬))⇒¬Ψ 1 A fundamental goal of Inconsistency Robust Direct Logic is to effectively reason about large amounts of pervasively inconsistent information using computer information systems.

  • How Peircean Was the “'Fregean' Revolution” in Logic?
    HOW PEIRCEAN WAS THE “‘FREGEAN’ REVOLUTION” IN LOGIC? Irving H. Anellis Peirce Edition, Institute for American Thought Indiana University – Purdue University at Indianapolis Indianapolis, IN, USA [email protected] Abstract. The historiography of logic conceives of a Fregean revolution in which modern mathematical logic (also called symbolic logic) has replaced Aristotelian logic. The preeminent expositors of this conception are Jean van Heijenoort (1912–1986) and Don- ald Angus Gillies. The innovations and characteristics that comprise mathematical logic and distinguish it from Aristotelian logic, according to this conception, created ex nihlo by Gottlob Frege (1848–1925) in his Begriffsschrift of 1879, and with Bertrand Rus- sell (1872–1970) as its chief This position likewise understands the algebraic logic of Augustus De Morgan (1806–1871), George Boole (1815–1864), Charles Sanders Peirce (1838–1914), and Ernst Schröder (1841–1902) as belonging to the Aristotelian tradi- tion. The “Booleans” are understood, from this vantage point, to merely have rewritten Aristotelian syllogistic in algebraic guise. The most detailed listing and elaboration of Frege’s innovations, and the characteristics that distinguish mathematical logic from Aristotelian logic, were set forth by van Heijenoort. I consider each of the elements of van Heijenoort’s list and note the extent to which Peirce had also developed each of these aspects of logic. I also consider the extent to which Peirce and Frege were aware of, and may have influenced, one another’s logical writings.

  • Augmenting Mathematical Formulae for More Effective Querying & Efficient Presentation
    Augmenting Mathematical Formulae for More Effective Querying & Efficient Presentation vorgelegt von Diplom-Physiker Moritz Schubotz geb. in Offenbach am Main von der Fakult¨atIV { Elektrotechnik und Informatik der Technischen Universit¨atBerlin zur Erlangung des akademischen Grades Doktor der Naturwissenschaften { Dr. rer. nat. { genehmigte Dissertation Promotionsausschuss: Vorsitzender: Prof. Dr. Odej Kao Gutachter: Prof. Dr. Volker Markl Gutachter: Prof. Abdou Youssef, PhD Gutachter: Prof. James Pitman, PhD Tag der wissenschaftlichen Aussprache: 31. M¨arz2017 Berlin 2017 ii Abstract Mathematical Information Retrieval (MIR) is a research area that focuses on the Information Need (IN) of the Science, Technology, Engineering and Mathematics (STEM) domain. Unlike traditional Information Retrieval (IR) research, that extracts information from textual data sources, MIR takes mathematical formulae into account as well. This thesis makes three main contributions: 1. It analyses the strengths and weaknesses of current MIR systems and establishes a new MIR task for future evaluations; 2. Based on the analysis, it augments mathematical notation as a foundation for future MIR systems to better fit the IN from the STEM domain; and 3. It presents a solution on how large web publishers can efficiently present math- ematics to satisfy the INs of each individual visitor. With regard to evaluation of MIR systems, it analyses the first international MIR task and proposes the Math Wikipedia Task (WMC). In contrast to other tasks, which evaluate the overall performance of MIR systems based on an IN, that is described by a combination of textual keywords and formulae, WMC was designed to gain insights about the math-specific aspects of MIR systems. In addition to that, this thesis investigates how different factors of similarity measures for mathematical expressions influence the effectiveness of MIR results.

  • A Program for the Semantics of Science
    MARIO BUNGE A PROGRAM FOR THE SEMANTICS OF SCIENCE I. PROBLEM, METHOD AND GOAL So far exact semantics has been successful only in relation to logic and mathematics. It has had little if anything to say about factual or empirical science. Indeed, no semantical theory supplies an exact and adequate elucidation and systematization of the intuitive notions of factual referen- ce and factual representation, or of factual sense and partial truth of fact, which are peculiar to factual science and therefore central to its philosophy. The semantics of first order logic and the semantics of mathematics (i.e., model theory) do not handle those semantical notions, for they are not interested in external reference and in partial satisfaction. On the other hand factual science is not concerned with interpreting a theory in terms of another theory but in interpreting a theory by reference to things in the real world and their properties. Surely there have been attempts to tackle the semantic peculiarities of factual science. However, the results are rather poor. We have either vigorous intuitions that remain half-baked and scattered, or rigorous formalisms that are irrelevant to real science. The failure to pass from intuition to theory suggests that semanticists have not dealt with genuine factual science but with some oversimplified images of it, such as the view that a scientific theory is just a special case of set theory, so that model theory accounts for factual meaning and for truth of fact. If we wish to do justice to the semantic peculiarities of factual science we must not attempt to force it into any preconceived Procrustean bed: we must proceed from within science.
