“Andre Gunder Frank was a pioneer of the emerging field of Global History, and within it of the perspective of the world system and its history. Like all great thinkers, and all great and important intellectual currents with a lasting historical legacy, his work, though enormously extensive and impressive in its own right, was also an aspect of a much larger and longer social and intellectual current, which will carry on his legacy and all those who also follow.” —Barry K. Gills, University of Helsinki , from the Afterword
