What vision of the future in this book of 1973! How was it possible to "guess" (without being mystical soothsayer) what would be the evolution of our society for the last 30 years? It's chilling to see the relevance of what could only be for a novel hypotheses. For thirty years the facts conform to the novel !!! It would nevertheless escape the epilogue! No doubt there must be an opening effort of the mind to accept a beginning that challenges us, makes us afraid even forcing us to admit of the turpitude which would be good feelings and that only reveals weakness, renunciation, flight distraught. And that, simply by refusing to see with courage the difficult but strong reality. Read overnight.
