the largest amount of work and, therefore, potential wealth from their workers. The fundamental nature of capitalist society is no different from that of a slave society in that one small group of society exploits the larger group. Through common ownership of the means of production, the profit motive is eliminated, and the motive of furthering human flourishing is introduced. Because the surplus produced by the workers is the property of the society as a whole, there are no classes of producers and appropriators. Additionally, as the state originates in the bands of retainers hired by the first ruling classes to protect their economic privilege, it will wither away as its conditions of existence have disappeared. Communism, revolution and socialism According to The Oxford Handbook of Karl Marx, "Marx used many terms to refer to a post-capitalist society—positive humanism, socialism, Communism, realm of free individuality, free association of producers, etc. He used these terms completely interchangeably. The notion that 'socialism' and 'Communism' are distinct historical stages is alien to his work and only entered the lexicon of Marxism after his death." According to orthodox Marxist theory, overthrowing capitalism by a socialist revolution in contemporary society is inevitable. While the inevitability of an eventual socialist revolution is a controversial debate among many different Marxist schools of thought, all Marxists believe socialism is a necessity. Marxists argue that a socialist society is far better for most of the populace than its capitalist counterpart. Prior to the Russian Revolution, Vladimir Lenin wrote: "The socialization of production is bound to lead to the conversion of the means of production into the property of society. ... This conversion will directly result in an immense increase in productivity of labour, a reduction of working hours, and the replacement of the remnants, the ruins of small-scale, primitive, disunited production by collective and improved labour." The failure of the 1905 Russian Revolution, along with the failure of socialist movements to resist the outbreak of World War I, led to renewed theoretical effort and valuable contributions from Lenin and Rosa Luxemburg towards an appreciation of Marx's crisis theory and efforts to formulate a theory of imperialism. Schools of thought Classical Classical Marxism denotes the collection of socio-eco-political theories expounded by Karl Marx and Friedrich Engels. As Ernest Mandel remarked, "Marxism is always open, always critical, always self-critical." Classical Marxism distinguishes Marxism as broadly perceived from "what Marx believed." In
