Translations of this book, which was published in Paris towards the end of 1967,[1] have already appeared in about ten or so countries, and, more often than not, several have been produced in the same language by competing publishers, and nearly always they are bad. The first translations everywhere were unfaithful and incorrect, with the exception of Portugal and possibly Denmark. The translations published in Dutch and German are good in their second versions, even though the German publisher on this occasion neglected to correct a large number of mistakes in the printing. In English and Spanish the third editions had to be awaited in order to know what I had really written. There was nothing worse than the situation it Italy, however, where, as early as 1968, the publisher De Donato put out the most monstrous one of all, which has only been partially improved upon by the two rival translations that followed. Moreover, Paolo Salvadori, having gone to find those responsible for this excess in their offices, had hit them and had even literally spat in their faces, for such is naturally the way good translators act when they meet bad ones. It suffices to say that the fourth Italian translation, which is by Salvadori, is excellent.
