There is no human failure greater than to launch a profoundly important endeavour and then leave it half done.

if we continue with what is surely our greatest Western temptation, and think that in some way history owes us a solution, that we can, by pursuing our own most parochial self-interest, achieve in some miraculous way a consummation of world order, then we are heading not simply towards great disappointments, but towards disaster and tragedy as well.
