The idea behind the construction of this book (a journey that leads us sheets in sheets according to the answers given to the questions the reader to orient) is original. The cards are often too simplistic. This book will render services to those who, not having a lot of humanities knowledge, discover analytical grids. For others, it will leave them in their hunger, because it's not surfing typologies and theories presented in a nutshell we can become what we want to be.
