So that economic man is situated in what we could call an indefinite field of immanence which,.on.the one hand, links him, in the form of dependence, to a series ofaccidents, and, on the other, links him, in the form of production, to the advantage of others, or which links his advantage to the production of the advantage of others. The convergence of interests thus doubles and covers the indefinite diversity of accidents. … The situation of homo reconomicus could therefore be described as doubly involuntary, with regard to the accidents which happen to him and with regard to the benefit he unintentionally produces for others. … So, we have a system in which homo reconomicus owes the positive nature of his calculation precisely to everything which eludes his calculation.
