It is worth considering more deeply just how necessity limits the universe of viable solutions and implementable plans. First, as we alluded to, the plan must in principle solve some real problem. Second, it must appeal to others—often in the face of competing plans—or those others will not cooperate and might well object. If I value something, therefore, I must determine how to value it so that others potentially benefit. It cannot just be good for me: it must be good for me and for the people around me.
