The arguments underlying Marx’s historical prophecy are invalid. His ingenious attempt to draw prophetic conclusions from observations of contemporary economic tendencies failed. The reason for this failure does not lie in any insufficiency of the empirical basis of the argument. Marx’s sociological and economic analyses of contemporary society may have been somewhat one-sided, but in spite of their bias, they were excellent in so far as they were descriptive. The reason for his failure as a prophet lies entirely in the poverty of historicism
