In Sung and Ming intellectual life, idealist philosophies came to the fore. Later, in the seventeenth and eighteenth centuries, to a number of Chinese thinkers, that predominance of idealism seemed a disaster, and they formally disavowed it. Is there an indication, perhaps, in the early existence of this group of materialists, that the seemingly stable, traditionalistic Chinese society had the capacity to develop under its own power, without a catalytic intrusion of Western industrialism, into a society with a scientific temper?
