Query: Excellent Introduction to an essential topic

As a student returning to school after a long absence, I felt I needed to brush up on some essential skills. Chief among these is critical thinking, as its use impacts everything we read, hear, and see to some extent. This book is an excellent introduction; it is clearly written, with each successive idea built firmly upon the previous ones. The authors use a minimum of jargon, and make no assumptions as to the reader's prior knowledge of logic or argument theory.I now have a command of the basic principles and terminology, and find myself making better arguments. More importantly, I can now spot flawed arguments as well as fallacies and rhetorical ploys that make up so much of public and political discourse. I expect to refer back to it many times in coming years.
