God As Both Ideal and Real Being in the Aristotelian Metaphysics
God As Both Ideal and Real Being In the Aristotelian Metaphysics Martin J. Henn St. Mary College Aristotle asserts in Metaphysics r, 1003a21ff. that "there exists a science which theorizes on Being insofar as Being, and on those attributes which belong to it in virtue of its own nature."' In order that we may discover the nature of Being Aristotle tells us that we must first recognize that the term "Being" is spoken in many ways, but always in relation to a certain unitary nature, and not homonymously (cf. Met. r, 1003a33-4). Beings share the same name "eovta," yet they are not homonyms, for their Being is one and the same, not manifold and diverse. Nor are beings synonyms, for synonymy is sameness of name among things belonging to the same genus (as, say, a man and an ox are both called "animal"), and Being is no genus. Furthermore, synonyms are things sharing a common intrinsic nature. But things are called "beings" precisely because they share a common relation to some one extrinsic nature. Thus, beings are neither homonyms nor synonyms, yet their core essence, i.e. their Being as such, is one and the same. Thus, the unitary Being of beings must rest in some unifying nature extrinsic to their respective specific essences. Aristotle's dialectical investigations into Being eventually lead us to this extrinsic nature in Book A, i.e. to God, the primary Essence beyond all specific essences. In the pre-lambda books of the Metaphysics, however, this extrinsic nature remains very much up for grabs. -
Aristotle's Assertoric Syllogistic and Modern Relevance Logic*
Aristotle’s assertoric syllogistic and modern relevance logic* Abstract: This paper sets out to evaluate the claim that Aristotle’s Assertoric Syllogistic is a relevance logic or shows significant similarities with it. I prepare the grounds for a meaningful comparison by extracting the notion of relevance employed in the most influential work on modern relevance logic, Anderson and Belnap’s Entailment. This notion is characterized by two conditions imposed on the concept of validity: first, that some meaning content is shared between the premises and the conclusion, and second, that the premises of a proof are actually used to derive the conclusion. Turning to Aristotle’s Prior Analytics, I argue that there is evidence that Aristotle’s Assertoric Syllogistic satisfies both conditions. Moreover, Aristotle at one point explicitly addresses the potential harmfulness of syllogisms with unused premises. Here, I argue that Aristotle’s analysis allows for a rejection of such syllogisms on formal grounds established in the foregoing parts of the Prior Analytics. In a final section I consider the view that Aristotle distinguished between validity on the one hand and syllogistic validity on the other. Following this line of reasoning, Aristotle’s logic might not be a relevance logic, since relevance is part of syllogistic validity and not, as modern relevance logic demands, of general validity. I argue that the reasons to reject this view are more compelling than the reasons to accept it and that we can, cautiously, uphold the result that Aristotle’s logic is a relevance logic.

Jewish Averroists Between Two Expulsions (1306-1492): from Conflict to Reconciliation
JEWISH AVERROISTS BETWEEN TWO EXPULSIONS (1306-1492): FROM CONFLICT TO RECONCILIATION Basem Mahmud Freie Universität Berlin ABSTRACT This article investigates the intellectual production of Jewish authors influenced by Averroes in the 14th and 15th Centuries in northern Spain and southern France. The primary objective is to determine the main features of Jewish Averroism in this period, and to understand it within its socio-historical context. The outcomes suggest that there was a relationship between the new social and political trends toward democratization and reconciliation in the heart of Jewish communities on one hand, and the growing interest in Averroes’ original works on the other. Original here means the works that are not commentaries or summaries of other works. Key words: Aristotelianism, Averroes, Averroism, Jewish philosophy, Kabbalah, Maimonides, Scripture. INTRODUCTION «There is nothing worse in social government than a policy that makes one single society into several, just as there is no greater good in communities than a policy that joins and unifies» (Averroes)1 The 14th Century was a very difficult time for Jewish communities in northern Spain and southern France, they faced great threats from outside as well as significant domestic division. The domestic conflict emerged not only because of religious and philosophical issues, but also due to economic and social matters related to the distribution of wealth and power within Jewish communities.2 In addition, these communities lived in delicate conditions due to threats from the Christians. This situation also had an effect on demographics. Since the last years of 13th Century, the Jewish community started to encounter sizeable obstacles in its demographic development.3 Under these conditions, Hebraic Averroism continued its development which had begun in XIII century. -

The Peripatetic Program in Categorical Logic: Leibniz on Propositional Terms
THE REVIEW OF SYMBOLIC LOGIC, Page 1 of 65 THE PERIPATETIC PROGRAM IN CATEGORICAL LOGIC: LEIBNIZ ON PROPOSITIONAL TERMS MARKO MALINK Department of Philosophy, New York University and ANUBAV VASUDEVAN Department of Philosophy, University of Chicago Abstract. Greek antiquity saw the development of two distinct systems of logic: Aristotle’s theory of the categorical syllogism and the Stoic theory of the hypothetical syllogism. Some ancient logicians argued that hypothetical syllogistic is more fundamental than categorical syllogistic on the grounds that the latter relies on modes of propositional reasoning such as reductio ad absurdum. Peripatetic logicians, by contrast, sought to establish the priority of categorical over hypothetical syllogistic by reducing various modes of propositional reasoning to categorical form. In the 17th century, this Peripatetic program of reducing hypothetical to categorical logic was championed by Gottfried Wilhelm Leibniz. In an essay titled Specimina calculi rationalis, Leibniz develops a theory of propositional terms that allows him to derive the rule of reductio ad absurdum in a purely categor- ical calculus in which every proposition is of the form AisB. We reconstruct Leibniz’s categorical calculus and show that it is strong enough to establish not only the rule of reductio ad absurdum,but all the laws of classical propositional logic. Moreover, we show that the propositional logic generated by the nonmonotonic variant of Leibniz’s categorical calculus is a natural system of relevance logic ¬ known as RMI→ . From its beginnings in antiquity up until the late 19th century, the study of formal logic was shaped by two distinct approaches to the subject. The first approach was primarily concerned with simple propositions expressing predicative relations between terms. -
Logic: a Brief Introduction Ronald L
Logic: A Brief Introduction Ronald L. Hall, Stetson University Chapter 1 - Basic Training 1.1 Introduction In this logic course, we are going to be relying on some “mental muscles” that may need some toning up. But don‟t worry, we recognize that it may take some time to get these muscles strengthened; so we are going to take it slow before we get up and start running. Are you ready? Well, let‟s begin our basic training with some preliminary conceptual stretching. Certainly all of us recognize that activities like riding a bicycle, balancing a checkbook, or playing chess are acquired skills. Further, we know that in order to acquire these skills, training and study are important, but practice is essential. It is also commonplace to acknowledge that these acquired skills can be exercised at various levels of mastery. Those who have studied the piano and who have practiced diligently certainly are able to play better than those of us who have not. The plain fact is that some people play the piano better than others. And the same is true of riding a bicycle, playing chess, and so forth. Now let‟s stretch this agreement about such skills a little further. Consider the activity of thinking. Obviously, we all think, but it is seldom that we think about thinking. So let's try to stretch our thinking to include thinking about thinking. As we do, and if this does not cause too much of a cramp, we will see that thinking is indeed an activity that has much in common with other acquired skills. -
Aristotle on Predication
DOI: 10.1111/ejop.12054 Aristotle on Predication Phil Corkum Abstract: A predicate logic typically has a heterogeneous semantic theory. Sub- jects and predicates have distinct semantic roles: subjects refer; predicates char- acterize. A sentence expresses a truth if the object to which the subject refers is correctly characterized by the predicate. Traditional term logic, by contrast, has a homogeneous theory: both subjects and predicates refer; and a sentence is true if the subject and predicate name one and the same thing. In this paper, I will examine evidence for ascribing to Aristotle the view that subjects and predicates refer. If this is correct, then it seems that Aristotle, like the traditional term logician, problematically conflates predication and identity claims. I will argue that we can ascribe to Aristotle the view that both subjects and predicates refer, while holding that he would deny that a sentence is true just in case the subject and predicate name one and the same thing. In particular, I will argue that Aristotle’s core semantic notion is not identity but the weaker relation of consti- tution. For example, the predication ‘All men are mortal’ expresses a true thought, in Aristotle’s view, just in case the mereological sum of humans is a part of the mereological sum of mortals. A predicate logic typically has a heterogeneous semantic theory. Subjects and predicates have distinct semantic roles: subjects refer; predicates characterize. A sentence expresses a truth if the object to which the subject refers is correctly characterized by the predicate. Traditional term logic, by contrast, has a homo- geneous theory: both subjects and predicates refer; and a sentence is true if the subject and predicate name one and the same thing. -
The History of Logic
c Peter King & Stewart Shapiro, The Oxford Companion to Philosophy (OUP 1995), 496–500. THE HISTORY OF LOGIC Aristotle was the first thinker to devise a logical system. He drew upon the emphasis on universal definition found in Socrates, the use of reductio ad absurdum in Zeno of Elea, claims about propositional structure and nega- tion in Parmenides and Plato, and the body of argumentative techniques found in legal reasoning and geometrical proof. Yet the theory presented in Aristotle’s five treatises known as the Organon—the Categories, the De interpretatione, the Prior Analytics, the Posterior Analytics, and the Sophistical Refutations—goes far beyond any of these. Aristotle holds that a proposition is a complex involving two terms, a subject and a predicate, each of which is represented grammatically with a noun. The logical form of a proposition is determined by its quantity (uni- versal or particular) and by its quality (affirmative or negative). Aristotle investigates the relation between two propositions containing the same terms in his theories of opposition and conversion. The former describes relations of contradictoriness and contrariety, the latter equipollences and entailments. The analysis of logical form, opposition, and conversion are combined in syllogistic, Aristotle’s greatest invention in logic. A syllogism consists of three propositions. The first two, the premisses, share exactly one term, and they logically entail the third proposition, the conclusion, which contains the two non-shared terms of the premisses. The term common to the two premisses may occur as subject in one and predicate in the other (called the ‘first figure’), predicate in both (‘second figure’), or subject in both (‘third figure’). -
The Distinction of Essence and Existence in Avicenna's
THE DISTINCTION OF ESSENCE AND EXISTENCE IN AVICENNA’S METAPHYSICS: THE TEXT AND ITS CONTEXT* Amos Bertolacci In his groundbreaking monograph Avicenna and the Aristotelian Tradition and in many other magisterial essays, Dimitri Gutas has underscored the key role that metaphysics plays in Avicenna’s phil- osophical system.1 Gutas’ account of metaphysics (as well as of the other main philosophical disciplines), in Avicenna’s œuvre is based on a full fledged methodology resulting from the critical evaluation of the assumptions of previous scholarship, an insightful analysis of the fundamental texts, and a thorough reconstruction of their doctrinal and historical context. All scholars interested in Avicenna’s metaphys- ics (not to say of his psychology, noetics and epistemology) and Arabic metaphysical speculation in general, can only be thankful to Gutas’ pioneering research for having explored and mapped what had been, to a large extent, virgin territory and for having provided a solid, bril- liant and comprehensive outline of the whole, thus paving the way to subsequent, more specific investigations. As a sign of personal heartfelt gratitude and in the footsteps of Gutas’ masterly approach outlined above, the present contribution wishes to provide the analysis of a crucial issue of Avicenna’s metaphysics.

The Enthymeme and the Rational Judge

PUB DATE Jun 74 NOTE 23p.; Paper presented at the Annual Meeting of the Western Speech Communication Association (Newport Beach, California, November 1974) EbiS PRICE MF-$0.76 HC-$1.58 PLUS POSTAGE DESCRIPTORS *Cognitive Processes; Educational Research; Higher Education; *Logic; *Logical Thinking; Productive Thinking; *Rhetoric; Thought Processes IDENTIFIERS *Enthymeme ABSTRACT This paper attempts to show that the significant difference between the enthymeme and the dialectic syllogism rests on the similarity of purpose of both dialectic and rhetoric, and on the differences in the respondents to which they address themselves. To support this thesis, the author reviews several contemporary approaches which have dealt with the enthymeme and develops an analysis of the essential requirements of dialectic and rhetoric which affect the characteristics f their respective syllogisms. The author predicts four essential characteristics of the enthymeme based on an assumption made by Aristotle that therhetorical respondent, while untrained in the assessment of arguments, still has an innate understanding and preference for logical reasoning. The four characteristics area(1) it must be short, simple, and to the point; (2) to accomplish this, the rhetorician must make use of common knowledge and draw obvious conclusions;(3) since one is arguing from propositions with which the auditor is already familiar, the enthymeme may be stylistically -

GRECO-ROMAN LEGAL ANALYSIS: THE TOPICS OF INVENTION MICHAEL FROST* I. INTRODUCTION Despite a wealth of commentary on legal reas6ning and legal logic, modern writers on the subject demonstrate a curious and re- grettable disregard for the close connections between classical Greco-Roman theories of forensic discourse and modern theories of legal reasoning and analysis. Two recent treatises on logic and legal reasoning, Judge Ruggero Aldisert's Logic for Lawyers' and Pro- fessor Steven Burton's An Introduction to Law and Legal Reason- ing,2 are exceptions to this rule. Their treatises fall within a 2,000- year-old tradition of rhetorical analysis and discourse especially designed for lawyers. Beginning with treatises on rhetoric by Aris- totle, Cicero, and Quintilian, philosophers and lawyers have re- peatedly attempted, some more ambitiously than others, to de- scribe and analyze legal reasoning and methodology. Judge Aldisert implicitly acknowledges his participation in this ancient tradition with an epigraph drawn from Cicero's Republic, with his choice of subject matter, and with his use of centuries-old rhetori- cal terminology.3 Professor Burton's approach to legal analysis and argument can also be traced back to ancient rhetorical treatises especially written for the instruction of beginning advocates.
