This book is part of the essential reading to understand or even and stop being sheep of a party, a religion, an NGO, a clan, of any group. It should nevertheless be ignored pseudoscientific theories on argone, contradicted by the facts. But his analysis of human nature and his criticism of the little man, ie the small unit forming the mass in any civilization, is very relevant. The direct style of the book little help to wake up those who delight in their neuroses, small shenanigans and physical and intellectual laziness.
