|Logic is about consistency - but t about all types of consistency. For example, if a man supports Arsenal one day and Spurs the next, then he is fickle but t necessarily illogical. If a legal system helps the rich but t the poor then it is unjust but t illogical. The type of consistency which concerns logicians is t loyalty or justice or sincerity, it is compatibility of beliefs. Logic, therefore, involves studying the situations in which a particular sentence is true or false, and the rules that determine whether a given argument is valid or invalid. Now fully revised and updated, Wilfrid Hodges' accessible study is the essential text for anyone who wants to learn about elementary logic. Assuming previous kwledge of the subject, it takes the reader through the whole gamut of logical expressions, symbols and tations in a simple and lively way. Many helpful examples are given, and for readers who are mathematically adventurous there are optional sections introducing rather more challenging material. This new edition also contains some additional exercises, with updated sections on formalization and semantics.|
