Seduced by a literary critic, I gives me that little book (60 pages) more common size by Editions de Minuit in their collection to 3 euros, as PUF. Anyway, here embedded me in reading this book that asks the very first pages, it is not in itself a huge hoax, much like the various recent publications philosopher Jean Baptiste Botul. This mini treaty teaches us through "5 fundamental laws" that stupidity rules the world. The author tells us, using graphs, moreover very directly inspired performances that economists (of which he was a prominent representative is said) that humans fall into four broad categories: intelligent, bandits, morons and stupid. The classification is done around the notions of profit for oneself and benefit for others (even a metaphor for economic reasoning of marginal utility for example). And that's it ..... The 60 pages of the book are very sparse, the graphs take whole pages, in short, little in the final text. Let's face it, if we can be disappointed by the brevity and superficiality about, diners in proportion to the exercise of very successful humorous style. A quick reading, fun and deeper than the tone of farce leaves imagine. The only minus for me: one can still expensive.
