This work by Alan Woods, provides a comprehensive explanation of the Marxist method of analysing history. This first part establishes the scientific basis of historical materialism. The ultimate cause of all social change is to be found, not in the human brain, but in changes in the mode of production.
Marxists do not see history as a mere series of isolated facts but rather, they seek to discover the general processes and laws that govern nature and society. The first condition for science in general is that we are able to look beyond the particular and arrive at the general. The idea that human history is not governed by any laws is contrary to all science.
