But if capitalism had built up science as a productive force, the very character of the new mode of production was serving to make capitalism itself unnecessary.
John Desmond Bernal (1959) Marx and Science. p. 39.
Production for sale in a market in which the object is to realize the maximum profit is the essential feature of a capitalist world-economy. In such a system production is constantly expanded as long as further production is profitable, and men constantly innovate new ways of producing things that will expand the profit margin.
Immanuel Wallerstein (1979) The Capitalist World-Economy. p. 15.
