MODE OF PRODUCTION (Marx) : Everything that goes into the production of the necessities of life, including the "productive forces" (labor, instruments, and raw material) and the "relations of production" (the social structures that regulate the relation between humans in the production of goods. According to Marx and Engels, for individuals, the mode of production is "a definite form of expressing their life, a definite mode of life on their part. As individuals express their life, so they are. What they are, therefore, coincides with their production, both with what they produce and how they produce" (42).
