Amin Maalouf, historical novelist of talent, gives us here a reflection on the theme of identity. Themes oh so significant and timely in these times of intolerance. The author reminds us - more than he shows us - the reality of identity of each of us is multiple, and this multitude uniquely identifies each individual and makes it different from others; thus no individual can claim to look like another. The individual may reject those who are different - the risk of being left alone - is condemned to live with others, and thus to learn to accept and respect. Amin Maalouf also speaks narrow ideas, ready-made opinions, ideological pressure, orchestrated propaganda, etc. which tend to highlight some of our identity and plots which, if we listen too, lead us straight to sectarianism and intolerance there. We are all concerned by this phenomenon; to each of us to open our eyes and be vigilant not to fall into the trap of those who try to manipulate us. Abandon its multi-identitarism is play the game of sectarianism and intolerance, is to renounce the light to the dark. A small book that can not be ignored and sobering, with sentences and simple words to everyone. Read and reread several times!
