One of the most outstanding features of Bolshevism has been its severe, exacting, even quarrelsome attitude towards the question of doctrine. The 26 volumes of Lenin’s works will remain forever a model of the highest theoretical conscientiousness. Without this fundamental quality Bolshevism would never have fulfilled its historic role. In this regard Stalinism, coarse, ignorant and thoroughly empirical, is its complete opposite.

The Opposition declared more than 10 years ago in its programme:

Since Lenin’s death a whole set of new theories has been created, whose only purpose is to justify the Stalin group’s sliding off the path of the international proletarian revolution.

Only a few days ago an American writer, Liston M. Oak, who has participated in the Spanish revolution, wrote:

The Stalinists are in fact today the foremost revisionists of Marx and Lenin – Bernstein did not dare go half as far as Stalin in revising Marx.

This is absolutely true. One must add only that Bernstein actually felt certain theoretical needs: he tried conscientiously to establish a correspondence between the reformist practices of social democracy and its programme. The Stalinist bureaucracy, however, not only had nothing in common with Marxism but is in general foreign to any doctrine or system whatsoever. Its “ideology” is thoroughly permeated with police subjectivism, its practice is the empiricism of crude violence. In keeping with its essential interests the caste of usurpers is hostile to any theory: it can give an account of its social role neither to itself nor to anyone else. Stalin revises Marx and Lenin not with the theoretician’s pen but with the heel of the GPU.
