Whenever, on the other hand, a man rebels faintly or vaguely against this way of speaking, whenever a man says that he cannot explain what he means, and that he hates argument, that his enemy is misrepresenting him, but he cannot explain how; that man is a true sage, and has seen into the heart of the real nature of language. Whenever a man refuses to be caught by some dilemma about reason and passion, or about reason and faith, or about fate and free-will, he has seen the truth. Whenever a man declines to be cornered as an egotist, or an altruist, or any such modern monster, he has seen the truth. For the truth is that language is not a scientific thing at all, but wholly an artistic thing, a thing invented by hunters, and killers, and such artists long before science was [Illustration: ORPHEUS AND EURYDICE.] dreamed of. The truth is simply that--that the tongue is not a reliable instrument, like a theodolite or a camera. The tongue is most truly an unruly member, as the wise saint has called it, a thing poetic and dangerous, like music or fire. Now we can easily imagine an alternative state of things, roughly similar to that produced in Watts’ allegories, a system, that is to say, whereby the moods or facts of the human spirit were conveyed by something other than speech, by shapes or colours or some such things. As a matter of fact, of course, there are a great many other languages besides the verbal. Descriptions of spiritual states and mental purposes are conveyed by a variety of things, by hats, by bells, by guns, by fires on a headland, or by jerks of the head. In fact there does exist an example which is singularly analogous to decorative and symbolic painting. This is a scheme of æsthetic signs or emblems, simple indeed and consisting only of a few elemental colours, which is actually employed to convey great lessons in human safety and great necessities of the commonwealth. It need hardly be said that I allude to the railway signals. They are as much a language, and surely as solemn a language, as the colour sequence of ecclesiastical vestments, which sets us red for martyrdom, and white for resurrection. For the green and red of the night-signals depict the two most fundamental things of all, which lie at the back of all language. Yes and no, good and bad, safe and unsafe, life and death. It is perfectly conceivable that a degree of flexibility or subtlety might be introduced into these colours so as to suggest other and more complex meanings. We might (under the influence of some large poetic station-masters) reach a state of things in which a certain rich tinge of purple in the crimson light would mean “Travel for a few seconds at a slightly more lingering pace, that a romantic old lady in a first-class carriage may admire the scenery of the forest.” A tendency towards peacock blue in the green might mean “An old gentleman with a black necktie has just drunk a glass of sherry at the station
