Pictures and Books 95 vii All words are juggles. To call a thing a juggle of words is often a bigger juggle than the juggle it is intended to complain of. The question is whether it is a greater juggle than is generally considered fair trading. viii Words are like money; there is nothing so useless, unless when in actual use. ix Gold and silver coins are only the tokens, symbols, out- ward and visible signs and sacraments of money. When not in actual process of being applied in purchase they are no more money than wTords not in use are language. Books are like imprisoned souls until some one takes them down from a shelf and reads them. The coins are potential money as the words are potential language, it is the power and will to apply the counters that make them vibrate with life; when the power and the will are in abeyance the counters lie dead as a log. The Law The written law is binding, but the unwritten law is much more so. You may break the written law at a pinch and on the sly if you can, but the unwritten law—which often com- prises the written—must not be broken. Not being written, it is not always easy to know what it is, but this has got to be done. Ideas They are like shadows—substantial enough until we try to grasp them. Expression The fact that every mental state is intensified by expres- sion is of a piece with the fact that nothing has any existence at all save in its expression. Development All things are like exposed photographic plates that have no visible image on them till they have been developed.
