Informed readers would probably know that Professor Lazarus is a reknown researcher in the field of psychology. This book is a highly readable account of how reason is related to emotion and stress (a theory which Lazarus calls cognitive-mediational). Though it is stated on the back cover of this book that it is intended for 'practitioners in the field of stress, appraisal, and coping, and... students of psychology, graduate students, academics, and professionals in related fields', the style in which this book is written makes it accessible even to the layperson who can tolerate a fair amount of not-so-difficult-to-understand jargon. But as a member of the book's targeted audience, I find that the book did not go into as much detail as I would had liked. Hence the rating I gave. As a layperson, I would probably give a 4-5 star rating. The book also makes an logically erroneous proposition that the scientific method is 'useless' in the investigation of individual differences. Overall, I find this a good book on how reason, emotion and stress can be related but the lay reader is cautioned against taking all of the author's statements as the gospel truth by virtue of his academic status.
