Marxist philosophy is dialectical materialism. When the dialectical materialist method is applied to the study of society the result is the science of society known as historical materialism. Marxist science, historical materialism is distinct from Marxist doctrine. Much of what was written by Marx, Engels, Lenin and others fall under the category of doctrine. Doctrine is a set of principles and policies that are applicable to a specific period of the revolutionary process. Doctrine is based on and flows from the scientific understanding of how societies develop and change.
