It must be clear that the purpose of this book is not to provide the ultimate truth about emotions. The book provides only a tentative classification of emotions with respect to their nature and complexity. It's obvious that all that is highly subjective, so everyone will have a different viewpoint with regard to whence comes this or that emotion, and what it really intends to express. However, the interest of this book is to make the reader think about his very emotions, to analyze a little bit the important social and learned components in most emotions. If you are interested in analyzing your very emotions, then this book may be useful. If you rather want to learn the definitive truth about the psychology of emotions, then better stop right now searching for something that does not exist...
