Representative government, a mystical institution, is said to have originated in some of the monastic orders. In any case, it is evident that the character of it is symbolic, and that it is subject to all the advantages and all the disadvantages of a symbol. Just exactly as a religious ritual may for a time represent a real emotion, and then for a time cease to represent anything, so representative government may for a time represent the people, and for a time cease to represent anything. But the peculiar difficulties attaching to the thing called representative government have not been fully appreciated. The great difficulty of representative governments is simply this: that the representative is supposed to discharge two quite definite and distinct functions. There is in his position the idea of being a picture or copy of the thing he represents. There is also the idea of being an instrument of the thing he represents, or a message from the thing he represents. The first is like the shadow a man throws on the wall; the second is like the stone that he throws over the wall. In the first sense, it is supposed that the representative is like the thing he represents. In the second case it is only supposed that the representative is useful to the thing he represents. In the first case, a parliamentary representative is used strictly as a parliamentary representative. In the second case a parliamentary representative is used as a weapon. He is used as a missile. He is used as something to be merely thrown against the enemy; and those who merely throw something against the enemy do not ask especially that the thing they throw shall be a particular copy of themselves. To send one's challenge is not to send one's photograph. When Ajax hurled a stone at his enemy, it was not a stone carved in the image of Ajax. When a modern general causes a cannon-ball to be fired, he is not understood to indicate that the contours of the cannon-ball represent in any exact way the curves of his own person. In short, we can in modern representative politics use a politician as a missile without using him, in the fullest sense of the word, as a symbol.
