Cabu, Charb, Tignous, Wolinski, among the twenty killed in the attacks in Paris on 7 and 9 January, these four were a kind of symbol. They were the priority targets. And why? Because they stood for intelligence against stupidity, reason against fanaticism, revolt against submission, courage against cowardice, sympathy against hatred, and for that specifically human quality: humour and laughter against conformism and dull self-righteousness.
