lack of the will-to-act when he said: "I act only when I can count on a 51 per cent probability of success." In that '51 per cent probability' we find the very root of the German collapse. The man who demands from Fate a guarantee of his success deliberately denies the significance of an heroic act. For this significance consists in the very fact that, in the definite knowledge that the situation in question is fraught with mortal danger, an action is undertaken which may lead to success. A patient suffering from cancer and who knows that his death is certain if he does not undergo an operation, needs no 51 per cent probability of a cure before facing the operation. And if the operation promises only half of one per cent probability of success a man of courage will risk it and would not whine if it turned out unsuccessful.
