Title: Flawed on Some Fundamentals
Product review: Not a fan of the truth-functional definition of "if...then" introduced on p. 11. An "if...then" should not change its truth value from case to case! An "if...then" is a generalization about all possible cases and is thus true IN ALL POSSIBLE CASES or false IN ALL POSSIBLE CASES! Neither am I a fan of the truth-functional definition of "iff" given on the same page. Like "if...then," an "iff" should not change its truth value from case to case! An "iff" is a generalization about all possible cases and is thus true IN ALL POSSIBLE CASES or false IN ALL POSSIBLE CASES!And this is only p. 11! Unfortunately these two flawed fundamental concepts taint the entire book. I cannot comfortably read this book because I am afraid what I'm reading might be based off of these misconceptions.This book needs a through revising, and it will not at all look the same once this is done.
