Rousseau: 'Two hunters lie in wait for a stag, which will feed them both amply. If they make a lot of noise, the stag will escape. The hunters are reasonably sure that the stag will eventually cross the path of their hiding place. Meanwhile, a rabbit appears on the path. If one hunter leaps out and kills the rabbit, he will eat; but the noise will scare off the stag and the other hunter will starve. The rabbit is guaranteed but the fear is the stag will never come. Both hunters would agree to wait for the stag, because they will both have more than enough food from it, but the rabbit is a paltry prize.'
