ABSTRACT
War is a conflict between two groups, each of which attempts to kill and maim as many as possible of the other group in order to achieve some object which it desires. The object is generally either power or wealth. It is a pleasure to exercise authority over other men, and it is a pleasure to live on the produce of other men's labour. The victor in war can enjoy more of these delights than the vanquished. But war, like all other natural activities, is not so much prompted by the end which it has in view as by an impulse to the activity itself. Very often men desire an end, not on its own account, but because their nature demands the actions which will lead to the end. And so it is in this case: the ends to be achieved by war appear in prospect far more important than they will appear when they are realized, because war itself is a fulfilment of one side of our nature. If men's actions sprang from desires for what would in fact bring happiness, the purely rational arguments against war would have long ago put an end to it. What makes war difficult to suppress is that it springs from an impulse, rather than from a calculation of the advantages to be derived from war.
