In the first place, it is a sort of note of exclamation prefixed to the sentence it introduces. Thus it infuses an emotional element into the statements which follow it. The word is a relic of the most primitive form of language. Judging from the sounds produced by animals and the cries of little children, we should conclude that the first approach to speech would be a simple expression of excitement--a scream of pain, a shout of delight, a yell of rage, a shriek of surprise. Next to the mere venting of feeling comes the utterance of desire--a request, either for the possession of some coveted boon, or for deliverance from something objectionable. Thus the dog barks for his bone, or barks again to be freed from his chain; and the child cries for a toy, or for protection from a terror. If this is correct it will be only at the third stage of speech that we shall reach statements of fact pure and simple. Conversely, it may be argued that as the progress of cultivation develops the perceptive and reasoning faculties and corresponding forms of speech, the primitive emotional and volitional types of language must recede. Our phlegmatic English temperament predisposes us to take this view. It is not easy for us to sympathise with the expressiveness of an excitable Oriental people. What to them is perfectly natural and not at all inconsistent with true manliness strikes us as a childish weakness. Is not this a trifle insular? The emotions constitute as essential a part of human nature as the observing and reasoning faculties, and it cannot be proved that to stifle them beneath a calm exterior is more right and proper than to give them a certain adequate expression. That this expression may be found even among ourselves is apparent from the singular fact that the English, who are the most prosaic people in their conduct, have given the world more good poetry than any other nation of modern times; a fact which, perhaps, may be explained on the principle that the highest poetry is not the rank outgrowth of irregulated passions, but the cultivated fruit of deep-rooted ideas. Still these ideas must be warmed with feeling before they will germinate. Much more, when we are not merely interested in poetic literature, when we are in earnest about practical actions, an artificial restraint of the emotions must be mischievous. No doubt the unimpassioned style has its mission--in allaying a panic, for example. But it will not inspire men to attempt a forlorn hope. Society will never be saved by hysterics; but neither will it ever be saved by statistics. It may be that the exclamation _how_ is a feeble survival of the savage _howl_. Nevertheless the emotional expression, when regulated as the taming of the sound suggests, will always play a very real part in the life of mankind, even at the most highly developed stage of civilisation.
