Just as the savage must wrestle with nature to satisfy his wants, to maintain and reproduce life, so must civilised man, and he must do so in all social formations and under all possible modes of production.
Karl MarxIn the eyes of dialectical philosophy, nothing is established for all times, nothing is absolute or sacred.
Karl MarxUnder no pretext should arms and ammunition be surrendered; any attempt to disarm the workers must be frustrated, by force if necessary.
Karl MarxThe ideas of the ruling class are in every epoch the ruling ideas, i.e. the class which is the ruling material force of society, is at the same time its ruling intellectual force. The class which has the means of material production at its disposal, has control at the same time over the means of mental production, so that thereby, generally speaking, the ideas of those who lack the means of mental production are subject to it. The ruling ideas are nothing more than the ideal expression of the dominant material relationships, the dominant material relationships grasped as ideas.
