 Mutual disinterest of the parties also means they are not moved by envy or rancor towards each other or others generally. This implies that the parties do not strive to be wealthier or better off than others for its own sake, and thus do not sacrifice advantages to prevent others from having more than they do. Instead, each party in the original position is motivated to do as well as he/she can in absolute terms in promoting the optimal achievement of the many purposes that make up a conception of the good, without regard to how much or how little others may have. For this reason they strive to guarantee themselves a share of primary social goods sufficient to enable them to pursue their (unknown) conception of the good.
