Terminology Tuesday: Modal Logic

Modal Logic: Study of reasoning about what must or might be the case, as well as what merely happens to be the case. The formalization of modal logic for the propositional calculus introduces special operators designating necessity and possibility (L and M). "It is necessary that p" (Lp) is interpreted to mean that p must be true in all possible worlds, and "It is possible that p" (Mp) that p is true in at least one possible world. On these interpretations,
Lp º ~M~p    is tautologous.1

Review: Asking the Right Questions by Browne & Keeley

Asking the Right Questions: A Guide to Critical Thinking (8th Edition) by M. Neil Browne and Stuart M. Keeley, as the title suggests, is all about critical thinking through a process of simply asking the right kinds of questions. However, this is a book that has the potential to change the way a person looks at and interacts with the world. This book helps one peel back the layers to thoroughly evaluate the issues and to think carefully. The authors define critical thinking: “critical thinking, as we will use the term, refers to the following: 1) awareness of a set of interrelated critical questions; 2) ability to ask and answer critical questions at appropriate times; and the 3) desire to actively use the critical questions.”1

15 Ways to Detect Nonsense

How do you avoid bad thinking? How do you detect nonsense? By nonsense we mean fallacious reasoning. Robert J. Gula's book Nonsense is a great place to start to begin to think critically and to spot fallacies in reasoning. (Review here.) It's a book that is thorough with an informal style with plenty of entertaining examples. If it's a fallacy, it's probably in this book. In the final note of the book, Gula distills the book into 15 principles. Here is that content: 15 Ways to Detect Nonsense:
  1. Be alert to anyone who speaks in absolutes: who uses words such as all, none, no one, never, always, everyone, must, immediately, or who refers to a group of people as if all the members have identical characteristics, beliefs, or attitudes.

Book Review: With Good Reason: An Introduction to Informal Fallacies by S. Morris Engel

Many are familiar with deductive arguments (where the conclusion necessarily follows from the premises) and inductive arguments (where the conclusion follows from the premises with a varying degree of probability and strength). But how well acquainted is one with “seductive”(40) arguments?

“Seductive” arguments are another name for informal fallacies, the subject S. Morris Engel takes up in his excellent book entitled With Good Reason: An Introduction to Informal Fallacies. In addition to the great content one will find in each chapter, the book is full of exercises (with an answer key at the end of each chapter for selected questions), diagrams, cartoons, and examples to help illustrate and reinforce the various points being made throughout the book on fallacies.
The book is divided into two parts: “Logic and Language” and “Informal Fallacies.”
