The initiative of the Five Year Plan and of the accelerated collectivization belongs entirely to the Left Opposition, in uninterrupted and sharp struggles with the Stalinists. Not having the possibility of occupying myself here with long historical researches, I will limit myself to a single illustration. The Dnieprostroy is considered with right as the highest achievement of Soviet industrialization. Yet [Joseph] Stalin and his followers ([Clim] Voroshilov and others) a few months before the beginning of the work were decided opponents of the Dnieprostroy plan.
Leon TrotskyTerror, as the demonstration of the will and strength of the working class, is historically justified, precisely because the proletariat was able thereby to break the political will of the intelligentsia, pacify the professional man of various categories and work, and gradually subordinate them to its own aims within the field of their specialties.
Leon TrotskyAs a general rule, man strives to avoid labor. Love for work is not at all an inborn characteristic: it is created by economic pressure and social education. One may even say that man is a fairly lazy animal. It is on this quality, in reality, that is founded to a considerable extent all human progress; because if man did not strive to expend his energy economically, did not seek to receive the largest possible quantity of products in return for a small quantity of energy, there would have been no technical development or social culture.
