The late Anthony Storr was British. As you read this insightful book, it is good to keep this in mind. He had a neighbor's perspective of Winston Churchill and (although centuries separate their lives) of Isaac Newton. These essays were the most valuable of the entire book. These men were two of the most influential men that the world has ever produced. With the knowledge of their exquisite gifts, emotionally both of these men had to conduct their lives. Churchill's 'black dog' makes us wonder if today he would have been able to hold a powerful public office, with society's fear of mental illness. Storr documents much of Churchill's emotional life and discusses Newton's also, which is very valuable to the reader. This book was written by one of the most prominent psychiatrists of the 20th Century, who in the same vein as the neurologist Oliver Sacks, fortunately decided to expand his career by publishing books.
