Muddles is a handbook of logical analysis, meant to be useful in clearing up confusions and bad arguments wherever we find them -- whether in the big issues of our time or in the less grandiose problems of our personal lives -- from what to do about terrorism or racism to what kind of car would be best to buy or what candidate to vote for in the next election. Here you will learn to spot muddled thinking. You will see how essential the subject of logic is in our lives.
