The content of this book is really interesting, you learn a lot. It is a journey through the history of mankind. Thanks to Sophie and Alberto we will discover the evolution of Western thought. Democritus (600 years AV JC) Jean-Paul Sartre, through Socrates, Aristotle, Spinoza, Freud and many other equally interesting characters. This book is a good presentation and a good introduction to the various philosophical currents.
The only hassle is all this embroidered story around this presentation. Laborious story that for my part I was a bit annoyed even if it leads to the book a little magical and surreal side.
