" What ways are there of getting human beings to do things? You can make a man fall over by pushing him; you cannot usefully make his hand write a letter or mix concrete by pushing; for in general if you have to push his hand in the right way, you might as well not use him at all. You can order him to do what you want, and if you have authority he will perhaps obey you. Again if you have power to hurt him or help him according as he disregards or obeys your orders, or if he loves you so as to accord with your requests, you have a way of getting him to do things. However, few people have authority over everyone they need to get to do things, and few people either have power to hurt or help others without damage to themselves or command affection from others to such an extent as to be able to get them to do the things they need others to do. Those who have extensive authority and power cannot exercise it to get all the other people to do the things that meet their mutual requirements. So though physical force seems a more certain way of producing desired physical results than any other, and authority and power to hurt or help and sometimes affection too, more potent than the feeble procedure of a language-game as the one with 'Bump!' that I described, yet in default of the possibility or utility of exerting physical force, and of the possibility of exercising authority or power to hurt and help, or of commanding affection, this feeble means is at least a means of getting people to do things. Now getting one another to do things without the application of physical force is a necessity for human life, and that far beyond what could be secured by those other means. "
