This extraordinarily well-written book encompasses an integrated approach to personality and its complexity. Needless to say, the field of personality is extremely intricate and dynamic. However, Pervin manages to provide a comprehensive yet lucid account of the most important approaches to personality. The strength of this book is that it integrates all the major perspectives. What is more, every chapter features key words, summaries and most importantly contributions and criticisms of each theory. The book is well structured and written in a way that captures the reader's attention. Thus, it is interesting, informative and extremely useful. Moreover, every theory gives its explanation to psychopathology and its possible causes. It should however be pointed out that this book is intended primarily for academic purposes. Nevertheless, I strongly recommend this book to all people who want to gain an insight into psychology at its best! After all, I think it is momentous to gain an insight into why some people develop maladaptive behavioral patterns and show systematic errors in thinking. Finally, this book attempts to answer the most difficult question pertaining to this dynamic field, namely: what factors contribute to the development of personality? Pervin clearly shows that interplay between biological and environmental determinants is necessary to provide an adequate explanation of personality. In my view, a theory that fails to intertwine both biological predispositions and environmental determinants with respect to personality is a flawed theory. Furthermore, a theory that cannot be disproved is a poor theory. In conclusion, this is truly an excellent book that integrates both descriptive and explanatory elements.
