Part A - Chapters 1 to 3

1.  THINKING WELL

Logic and reasoning along with a general awareness toward thinking better is clearly useful for both communication and making life decisions in general. Although most people consider their thinking skills as being above average, it is advised to at least skim these first three chapters.  Most of us can use a refresher.

The three foundational topics of Openness, Reductionism and Greyness are covered here, hopefully leading to improved techniques for considering problems.

2REASONING

Basic argumentation and core methods of reasoning are reviewed including the usual two of deduction and induction, along with four other important ones to be aware of. 

The blurring between deduction and induction is carefully noted in particular — with probability emphasized as too commonly being the “missing premise”.

This is a good overall review of the issues between the practical and the rigorous, and for where various dangers can unconsciously occur (see "Poets and Mathematicians").

3FALLACIES

This is essentially about shortcut methodology that identifies problem argumentation. These are conveniently categorized into only four "DISE" sections that are easily memorized — Deductive, Inductive, Source and Emotional.

Everyday life tends to unconsciously apply fallacies as opposed to using the direct methodology of deduction and induction for logic. Without a simple categorized method of recall, fallacies can tend to be rather difficult to remember.

The Strawman is featured for the first one, being that it often covers all four categories. Be on guard for misrepresentations whenever you hear something like, "So you are saying _____". Do not let people put words in your mouth.

Short but relevant illustrations of each fallacy are given.
