This book is a bomb. Written in 1961, it is incredibly relevant. In reading at the age of 36, I wondered why nobody had told me before that such a book existed. He revealed to me many things I wanted, or perhaps I knew without being really aware. The research, discoveries, principles and practices are exposed with educational clarity and scientific rigor. I discovered an author, a great man, a scientist, a psychologist unusual and off the beaten track that speaks in the first person singular, with simplicity of the interior life and the evolution of individuals. Doeuvre a leader who allowed me to better understand myself and accept myself as I am. A revealing that inspires my work and my personal transformations for more than 10 years now. I envy anyone who enters this book with curiosity to discover Carl Rogers and his deep approach of empathy and counseling.
