"With the greatest enthusiasm we welcome the republication of Reason in Revolt in Spanish. In the six years since the book was first published in English and Spanish it has received a favourable response from many parts of the world, both from labour movement activists and from scientists. Interest in our ideas has been expressed in many countries. It has so far been translated into Spanish, Italian, Greek, Urdu and Turkish, and new translations are being prepared in German and Dutch." Alan Woods and Ted Grant comment on the latest scientific discoveries in genetics, black holes and the Big Bang, and how they confirm the views put forward in Reason in Revolt six years ago.
