‘Why are you moving your arm up and down?‘ ‚To operate the pump‘, and he is operating the pump, ‚‘Why are you pumping?‘ ‚To replenish the water-supply‘ and he is replenishing the water-supply; ‚Why are you replenishing the water-supply?‘ ‚’To poison the inhabitants‘ and he is poisoning the inhabitants, for they are getting poisoned. (Anscombe 1963, 40)
