This book is for people who find themselves beset by arguments: persuasions open and hidden, put forward in books or on buses, blown up onto hoardings or piped right into the home by television and radio. Such arguments may need to be critically weighed and cautiously assessed, if the arguee is not to be taken for a ride. For such analysis, some introduction to logic is required. This book explains how to decide which arguments are sound and what makes the bad ones bad.
