This book has more than 40 years. Some of its elements are somewhat overwhelmed ... Yet the opening state of mind of its authors is now furiously trendsetter. Pauwels and Bergier are quick to overcome the limits of their time to explore other ways of knowing and knowledge. They speculate, mention designers or scientists who have revolutionized the world of knowledge. With them, nothing is fixed, nothing is cast in bronze of the single thought. My God, that's refreshing. Above all, this book is reacted drive. Consistently, our common sense is challenged by a prompt to better see the world around us. Really, this book is far from obsolete. It is even more modern today than yesterday.
