## Main Question or Discussion Point

Hi there, thanks for coming to the thread about the single most widely abused word in all of internet discussion forumdom:

A few months back, I decided to pick up a textbook on the subject and work through it cover to cover. I’m about halfway done, but I thought I’d present the notes I made here for discussion. I’d like to do something similar to what I am trying to do in my QFT thread in the Homework forum (and hopefully revive that thread, too). Anywho, the book is called Logic (duh) by Robert Baum, although you will not need a copy of the book to follow this thread. My notes are formatted like a geometry textbook, with definitions, axioms and theorems numbered. It is supposed to be a first undergraduate course in logic, so I presume that the only prerequisite is a high school education. I think that this is probably the most overdue topic in the philosophy forum, and maybe even all of PF in general.

Also, in just about every discussion in the Philosophy forum with which I get involved, it seems that it always boils down to a discussion of (and disagreement over) “what logic is”. Since I don’t have time to keep up with all those threads, I’m going to consolidate here.

The structure of the book is as follows:

.....Chapeter 0: Introduction

.....Chapter 1: Categorical Statements

.....Chapter 2: Categorical Syllogisms

.....Chapter 3: Truth-Functional Propositions

.....Chapter 4: Propositional Logic

.....Chapter 5: Quantificational Logic by David T. Wieck

.....Chapter 6: Enumerative Induction

.....Chapter 7: Hypothetico-Deducitve Method

.....Chapter 8: Mill’s Methods

.....Chapter 9: Probability

.....Chapter 10: Ordinary Language

.....Chapter 11: Definitions

.....Chapter 12: Informal Fallacies

Ready? Here we go.
