The first fallacy of Communism is its attempt to over-simplify history. Marx and Engels attempted to change history from a fluid stream, fed by human activities from millions of tributaries, into a fixed, undeviating, pre-determined course of progress which could be charted in the past and predicted for the future on the basis of a single, simple criterion - economics. Obviously economics have played a vital and powerful role in human history but so have climate, topography, access to oceans and inland waterways, mechanical inventions, scientific discoveries, national and racial affinities, filial affection, religion, desire for explanatory adventure, sentiments of loyalty, patriotism and a multitude of other factors.
