DIALECTICAL MATERIALISM 131
But if a man whose proletarian background and
membership in the workers' class cannot be contested
diverges from the correct Marxian creed, he is a traitor.
It is impossible to assume that he could be sincere in
his rejection of Marxism. As a proletarian he must nec-
essarily think like a proletarian. An inner voice tells him
in an unmistakable way what the correct proletarian
ideology is. He is dishonest in overriding this voice and
publicly professing unorthodox opinions. He is a rogue,
a Judas, a snake in the grass. In fighting such a betrayer
all means are permissible.
Marx and Engels, two men of unquestionable bour-
geois background, hatched out the class ideology of the
proletarian class. They never ventured to discuss their
doctrine with dissenters as scientists, for instance, dis-
cuss the pros and cons of the doctrines of Lamarck, Dar-
win,
Mendel, and Weismann. As they saw it, their ad-
versaries could only be either bourgeois idiots
x
or pro-
letarian traitors. As soon as a socialist deviated an inch
from the orthodox creed, Marx and Engels attacked him
furiously, ridiculed and insulted him, represented him
as a scoundrel and a wicked and corrupt monster. After
Engels' death the office of supreme arbiter of what is
and what is not correct Marxism devolved upon Karl
Kautsky. In 1917 it passed into the hands of Lenin and
became a function of the chief of the Soviet govern-
ment. While Marx, Engels, and Kautsky had to content
themselves with assassinating the character of their op-

E.g., "bourgeois stupidity" (about Bentham, Das Kapital, 1,
574),
"bourgeois cretinism" (about Destutt de Tracy, ibid., 2, 465),
and so on.
