This is an introduction to the philosophy that reads like a novel (unlike the World Sophie who wants to be a novel, but ...), exciting, opening wide the doors of the world of "Ideas" and giving desire to s' rush at full speed in deepening what marked us ... In the process, I bought and devoured books by and about Spinoza, Nietzsche, and even St. Augustine ... A generally accessible to neophytes vocabulary (like me) who can not regret checking sometimes (not often) a word in the dictionary ... Would recommend without moderation, with no age limit (not for young generations ...!).
