I have just received yet another collection of Stalin’s writings, this one called Stalin on China. But what drew my eye on opening it is the preface by Chen Pota, from 1949:

On the basis of concrete analysis of the concrete conditions in China, Stalin, this great scientist of dialectical materialism, the teacher of world revolution, formulates at the time of the first Great Revolution of China, a series of questions concerning the Chinese revolution, to which he offers extremely brilliant solutions. By this means he demolished the nonsense on the question of China advanced by the counter-revolutionary Trotskyites and assisted the Communist Party of China to embark on the path of Bolshevism.

Great scientist of dialectical material, teacher of world revolution, brilliant solutions … and above all, concrete. You don’t find reviews like that any more – except perhaps self-written pieces on academic profile pages.
