ABSTRACT
In the previous Chapter we considered one of the important implications for governmental policy arising from the fact that, as we pointed out in Chapter XIII, the number of possible future environmental paths is always so great that decision-makers cannot possibly consider what their future actions would be along each conceivable environmental path. There will remain much residual uncertainty; one object in the formulation of any present plan must be simply to put the planner into a flexible position so as to be able to react quickly and appropriately to unexpected, unforeseen events to meet which no carefully premeditated course of action has been prepared in advance.
