"There is in fact a category of people who get unusually close to the truth about themselves and the world. Their self-perceptions are more balanced, they assign responsibility for success and failure more even-handedly, and their predictions for the future and more realistic. These people are living testimony to the dangers of self-knowledge. They are the clinically depressed".
