Marxism is the tradition of thought and practice founded by Marx. To be identifiable as Marxism any phase of this tradition must have important resemblances to Marx's own work, and those resemblances must be conscious and acknowledged. Anti-Marxists tend to interpret this relation according to a derogatory religious model. Marxists, they suppose, treat Marx as an authority and follow their leader wherever he leads, instead of following the argument wherever it leads. On this view Marxism has an essentially scholarly relation to Marx and a polemical relation to everything else: it seeks to identify exactly what Marx said and thought, to preserve the master's teaching in all its original purity, and to appeal to it for correct answers to the substantive questions that we face. In other words, Marxism is that tradition which treats the works of Marx as a bible and imagines that it can clinch substantive arguments with the words ‘Marx has said it’.
