  • Categorize" a Person, Place, Time, Thing, Or Situation Is to Characterize It As a Member of a Class of Similar Things
    CHAPTER 2 CATEGORICAL PROPOSITIONS A. The Structure of Categorical Propositions To "categorize" a person, place, time, thing, or situation is to characterize it as a member of a class of similar things. One does not consider the thing in question from its purely individual point of view, that is, in terms of the qualities it has without relationship to any other things. Upon being categorized, an individual thing is known by properties that it has by virtue of its being a member of the class of things referred to by that category. All propositions expressed in the Aristotelian system of logic are called categorical propositions because they are constructed using two categories of things: the subject category (or class) and the predicate category (or class). The copula, or connector between the subject and predicate, of a categorical proposition indicates how its subject category is related to its predicate category. The copula specifies whether members of the subject category are also members of the predicate category or whether members of the subject category are not members of the predicate category. Illustration: Subject Copula Predicate Quality of Copula (1) Strawberries are red. Affirmative (2) Strawberries are not red. Negative However, this is not enough. (1) declares that members of the class of strawberries are also members of the class of red things, but (1) is ambiguous because it does not specify the quantity of the subject class that is included in the predicate class. Thus, Ms. A might take (1) to mean “all strawberries are red,” while Mr. B might take (1) to mean “some strawberries are red.” Ms.

The term refers to the argument in which a proposition is arrived at and affirmed or denied on the basis of one or more other propositions accepted as the starting point of the process. To determine whether or not an inference is correct the logician examines the propositions that are the initial and end points of that argument and the relationships between them. This clearly denotes the significance of propositions in the study of logic. In this unit you are expected to study: • the nature • the definition • the types and forms of propositions • the difference between propositions and sentences and judgments • the description of various types of propositions viewed from different standpoints like, composition, generality, relation, quantity, quality, and modality. 4.1 INTRODUCTION Classical logic concerns itself with forms and classifications of propositions. We shall begin with the standard definition of proposition. A proposition is a declarative sentence which is either true or false but not both. Also a proposition cannot be neither true nor false. A proposition is always expressed with the help of a sentence. For example - the same proposition “It is raining” can be expressed in English, Hindi, and Sanskrit and so on.

  • Immediate Inference
    Immediate Inference Dr Desh Raj Sirswal, Assistant Professor (Philosophy) P.G. Govt. College for Girls, Sector-11, Chandigarh http://drsirswal.webs.com . Inference Inference is the act or process of deriving a conclusion based solely on what one already knows. Inference has two types: Deductive Inference and Inductive Inference. They are deductive, when we move from the general to the particular and inductive where the conclusion is wider in extent than the premises. Immediate Inference Deductive inference may be further classified as (i) Immediate Inference (ii) Mediate Inference. In immediate inference there is one and only one premise and from this sole premise conclusion is drawn. Immediate inference has two types mentioned below: Square of Opposition Eduction Here we will know about Eduction in details. Eduction The second form of Immediate Inference is Eduction. It has three types – Conversion, Obversion and Contraposition. These are not part of the square of opposition. They involve certain changes in their subject and predicate terms. The main concern is to converse logical equivalence. Details are given below: Conversion An inference formed by interchanging the subject and predicate terms of a categorical proposition. Not all conversions are valid. Conversion grounds an immediate inference for both E and I propositions That is, the converse of any E or I proposition is true if and only if the original proposition was true. Thus, in each of the pairs noted as examples either both propositions are true or both are false. Steps for Conversion Reversing the subject and the predicate terms in the premise. Valid Conversions Convertend Converse A: All S is P.

  • 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.

  • Testing Validity Using Venn's Diagrams
    TESTING VALIDITY USING VENN'S DIAGRAMS To test the validity of a categorical syllogism, one can use the method of Venn diagrams. Since a categorical syllogism has three terms, we need a Venn diagram using three intersecting circles, one representing each of the three terms in a categorical syllogism. A three term diagram has eight regions (the number of regions being 2n where n is the number of terms). The following chart gives the extension of the predicates in the various regions of the diagram. Region S (Minor Term) P (Major Term) M (Middle Term) 1 yes no no 2 yes yes no 3 no yes no 4 yes no yes 5 yes yes yes 6 no yes yes 7 no no yes 8 no no no In order to use a Venn diagram to test a syllogism, the diagram must be filled in to reflect the contents of the premises. Remember, shading an area means that that area is empty, the term represented has no extension in that area. What one is looking for in a Venn diagram test for validity is an accurate diagram of the conclusion of the argument that logically follows from a diagram of the premises. Since each of the premises of a categorical syllogism is a categorical proposition, diagram the premise sentences independently and then see whether the conclusion has already been diagramed. If so, the argument is valid. If not, then it is not. Remember, one definition of validity is that the propositional (informational) content of the conclusion is already expressed in the premises.

The semantics of the modal syllogistic are interpreted in a way that is motivated by Aristotle, and also make his validity claims in the Prior Analytics consistent to a higher degree than previously developed interpretative models. In Chapter One, ancient and contemporary objections to the Aristotelian modal syllogistic are discussed. A resolution to apparent inconsistencies in Aristotle’s modal syllogistic is proposed and developed out of recent work by Patterson, Rini, and Malink. In particular, I argue that the semantics of negation is distinct in modal context from those of assertoric negative claims. Given my interpretive model of Aristotle’s semantics, in Chapter Two, I provide proofs for each of the mixed apodictic syllogisms, and propose a method of using Venn Diagrams to visualize the validity claims Aristotle makes in the Prior Analytics.

The zero symbol, 0, is used for this purpose. To say that the class designated by the term S has no members, we write an equals sign between S and 0. Thus the equation S ϭ 0 says that there are no S’s, or that S has no members.

  • Venn Diagrams Part 1
    4.3 Venn Diagrams, part 1 1. Aristotle vs. Boole: Before moving on, it will be helpful to gain some understanding of what “existential import” is. Existential Import: A statement has existential import if it implies that something exists. For instance, consider the two sorts of “particular” categorical propositions: “Some pizza has pepperoni on it.” (Some S are P) “Some cookies do not have chocolate chips.” (Some S are not P) The first statement implies that pizza exists (there IS some pizza somewhere, and it has pepperoni on it). The second implies that cookies exist (there ARE some cookies somewhere, and they don’t have chocolate chips in them). Because these propositions imply something about what exists, we say that they have “existential import”. But, now consider the two sorts of “universal” categorical propositions: “All oceans are salty.” (All S are P) “No rocks are alive.” (No S are P) Do these imply that there ARE some oceans and rocks in existence? There is some disagreement about this. Aristotle (~350 B.C.) thought the answer was clearly yes, while George Boole (~1850 A.D.) thought the answer was no. Boole: Universal propositions do not imply existence: To understand why Boole thought universal categorical propositions did NOT have existential import, consider these two statements: “All unicorns are magical.” (All S are P) “No hobbits are very tall.” (No S are P) Do these statements imply that there ARE some unicorns and hobbits? Surely not! This fact led Boole to conclude that universal categorical propositions NEVER imply anything about existence. If I tell you that “All oceans are salty”, this does not ENTAIL that there ARE any oceans.

  • The Operations of Conversion, Obversion and Contraposition Are Applied to Categorical Propositions to Yield New Categorical Propositions
    4.4 CONVERSION, OBVERSION AND CONTRAPOSITION The operations of conversion, obversion and contraposition are applied to categorical propositions to yield new categorical propositions. Conversion consists of simply switching the subject term with the predicate term while leaving the quality and quantity of the proposition unaltered. The result of applying conversion to a categorical proposition is called the converse of the proposition. Thus, for example, the converse of “All dogs are mammals” is “All mammals are dogs.” The converses of E and I propositions are logically equivalent to them (that is, they necessarily have the same truth values.) The converse of A and O propositions are not, in general, logically equivalent to them. Similarly, if we form an argument whose premise is a categorical proposition and whose conclusion is the converse of it, then the argument is valid if the premise is an E and I proposition and, in general, is invalid if the premise is an A or an O proposition. Obversion consists of both (1) changing the quality of the proposition (leaving the quantity the same), and (2) complementing the predicate term. To complement the predicate term, one typically attaches the prefix “non-“ to it. The result of obversion is called obverse of the proposition to which it is applied. The obverse of any categorical proposition, A, E, I or O, is logically equivalent to it. Any argument whose premise is a categorical proposition and whose conclusion is its obverse is a valid argument. Contraposition consist of both (1) switching the subject with the predicate term (while leaving the quality and quantity of the proposition unaltered), and (2) complementing both terms.

  • Baronett, Logic (4Th Ed.) Chapter Guide Chapter 5: Categorical
    Baronett, Logic (4th ed.) Chapter Guide Chapter 5: Categorical Propositions The study of categorical propositions includes the logical structure of individual categorical propositions (how the subject and predicate classes relate to each other), as well as how correct reasoning proceeds from one categorical proposition to another. A. Categorical Propositions Categorical propositions are statements about classes of things. A class is a group of objects. There are two class terms in each categorical proposition, a subject class (S) and a predicate class (P). There are four types of categorical proposition: A-proposition: Asserts that the entire subject class is included in the predicate class. o Standard-form of the A-proposition: All S are P. o This is the universal affirmative proposition. I-proposition: Asserts that at least one member of the subject class is included in the predicate class. o Standard-form of the I-proposition: Some S are P. o This is the particular affirmative proposition. E-proposition: Asserts that the entire subject class is excluded from the predicate class. o Standard-form of the E-proposition: No S are P. o This is the universal negative proposition. O-proposition: Asserts that at least one member of the subject class is excluded from the predicate class. o Standard-form of the O-proposition: Some S are not P. o This is the particular negative proposition. B. Quantity, Quality, and Distribution Categorical propositions can be viewed in terms of quantity (universal or particular), quality (affirmative or negative) and whether or not a class is distributed. If a categorical proposition asserts something about every member of a class, then the term designating that class is said to be distributed.

  • A History of Quantification
    A History of Quantification Daniel Bonevac September 15, 2011 Aristotle (384–322 BC), the founder of the discipline of logic, also founded the study of quantification. Normally, Aristotle begins a topic by reviewing the common opinions, including the opinions of his chief predecessors. In logic, however, he could not adopt the same strategy; before him, he reports, “there was nothing at all” (Sophistical Refu- tations 183b34–36). Aristotle’s theory dominated logical approaches to quantification until the nineteenth century. That is not to say that others did not make important contributions. Medieval lo- gicians elaborated Aristotle’s theory, structuring it in the form familiar to us today. They also contemplated a series of problems the theory generated, devising increas- ingly complex theories of semantic relations to account for them. Textbook treatments of quantification in the seventeenth and nineteenth centuries made important contribu- tions while also advancing some peculiar theories based on medieval contributions. Modern quantification theory emerged from mathematical insights in the middle and late nineteenth century, displacing Aristotelian logic as the dominant theory of quantifiers for roughly a century. It has become common to see the history of logic as little more than a prelude to what we now call classical first-order logic, the logic of Frege, Peirce, and their successors. Aristotle’s theory of quantification is nevertheless in some respects more powerful than its modern replacement. Aristotle’s theory com- bines a relational conception of quantifiers with a monadic conception of terms. The modern theory combines a monadic conception of quantifiers with a relational theory of terms.
