　　Passage 3

　　When a new movement in art attains a certain fashion, it is advisable to find out what its advocates are aiming at, for, however farfetched and unreasonable their principles may seem today, it is possible that in years to come they may be regarded as normal. With regard to Futurist poetry, however, the case is rather difficult, for whatever Futurist poetry may be even admitting that the theory on which it is based may be right, it can hardly be classed as Literature.

　　This, in brief, is what the Futurist says; for a noise and violence and speed. Consequently, our feelings, thoughts and emotions have undergone a corresponding change. This speeding up of life, says the Futurist, requires a new form of expression. We must speed up our literature too, if we want to interpret modern stress. We must pour out a large stream of essential words, unhampered by stops, or qualifying adjectives, of finite verbs. Instead of describing sounds we must make up words that imitate them;we must use many sizes of type and different colored inks on the same page, and shorten or lengthen words at will.

　　Certainly their descriptions of battles are confused. But it is a little upsetting to read in the explanatory notes that a certain line describes a fight between a Turkish and a Bulgarian officer on a bridge off which they both fall into the river and then to find that the line consists of the noise of their falling and the weights of the officers: Pluff! Pluff! A hundred and eighty-five kilograms.

　　This, though it fulfills the laws and requirements of Futurist poetry, can hardly be classed as Literature. All the same, no thinking man can refuse to accept their first proposition: that a great change in our emotional life calls for a change of expression. The whole question is really this: have we essentially changed?
