By Frederic Tamler Sommers, George Englebretsen, Harry A. Wolfson, Fred Sommers

This paintings introduces the topic of formal common sense in terms of a approach that's "like syllogistic logic". Its process, like out of date, conventional syllogistic, is a "term logic". The authors' model of common sense ("term-function logic", TFL) stocks with Aristotle's syllogistic the perception that the logical different types of statements which are keen on inferences as premises or conclusions will be construed because the results of connecting pairs of phrases by way of a logical copula (functor). This perception contrasts markedly with that which informs cutting-edge usual formal common sense ("modern predicate logic", MPL). The booklet is meant as a device for the advent of TFL to the start scholar of good judgment. additionally it is a bankruptcy introducing usual MPL. There are numerous workout sections and a precis of the most ideas, legislation and ideas of TFL. For the philosophically orientated there are discussions of vital matters on the intersections of semantics, metaphysics, epistemology and common sense.

Logik im Recht: Grundlagen und Anwendungsbeispiele

In dem Lehr- und Studienbuch zeigt der Autor, in welchem Maße logische Strukturen das Rechtsdenken bestimmen. Er erläutert die wesentlichen logischen Grundlagen und ihre Anwendung auf dem Gebiet des Rechts. Zum einen führt dies zu einem tieferen Verständnis der juristischen Dogmatik und einer systematischen Durchdringung des Rechtsstoffs, zum anderen tragen die Überlegungen zwischen Logik und Rechtswissenschaft zu neuen Erkenntnissen bei.

Example text

In dealing with the structure of any sentence, the logician is out to make its logical syntax explicit. How does the logician analyze the two sentences? To see the how and why of his analysis we note that the pattern of the inference in which we move from the premise 'some horse speaks French' to 'some speaker of French is a 42 An Invitation to Formal Reasoning horse' involves a change of order in two expressions. In explaining why this inference is valid we want to say that the form of both sentences is the same, only that in the conclusion the order of two expressions contained in the premise has been switched.

Logic is exclusively concerned with statements because only statements claim truth for the propositions they express and so only statements are evaluated as being true or false. Logicians speak of a statement's 'truth value'; it has the value True if it is true and the value False if it is false. Picturing Propositions 39 9. Truth Relations One may accept or reject a truth claim. If you accept a statement as true, then you are rationally committed to accept certain other statements as true. For example, anyone who accepts 'some farmer is a gentleman and a scholar' as true is rationally committed to accept 'some scholar is a farmer and a gentleman' and 'some gentleman is a scholar' as true.

Introduction Any argument consists of statements. In this chapter and the next we will be learning how to represent statements in a way that makes it easy to manipulate them, 'adding them up' to arrive at conclusions. Our task here is similar to the task we once had of learning 'the language of mathematics'. As a first step we learned how to represent numbers like seven hundred and thirty-one and nine thousand six hundred and ninety-eight as 731 and 9,698. Using arabic notation made it easy for us to add these numbers in a mechanical way to get 10,429 as the sum.
