The cooperative system is fundamental to the organization and structure of a Prout (the Progressive Utilization Theory) economy. It is an expression of economic democracy in action - cooperative enterprises give workers the right of capital ownership, collective management and all the associated benefits, such as profit sharing. Prabhat Ranjan Sarkar, the propounder of Prout, goes further and argues that an egalitarian society is actually not possible without a commitment to the cooperative system. The commitment is not just to an economic order but also to a cooperative ethic and culture. This essay explores some of the scientific evidence that humans have a predisposition to cooperation and in particular to economic cooperation. The evidence comes from a new and exciting field of research known as neuro-economics. We then turn to those insights provided by sociological studies.
