Imagine a notebook in which you write everything that you learn every day not to forget; or in which you record your thoughts on a variety of subjects, ranging from history to psychology, through science, spirituality, puzzles, recipes and many more topics! Well, ESRA is the notebook of Bernard Werber (at least that's how I see it)! In this book, the author shares his knowledge without ever being pedantic and allows us to learn while entertaining us, and know many stories which we may never would have heard otherwise. The inputs are short enough and varied and often you wonder "Where did he go get that?" In short, this reading is also pleasing it is stimulating to the mind, and I can only recommend it to all those who love to learn ... it surely will open new horizons ...
