But from the front seat on the top of an omnibus on a sunny September afternoon, the Strand, and Charing Cross corner, and Whitehall, and the great multitude of people, the great uproar of vehicles, streaming in all directions, is apt to look a world altogether too formidable. It has a glare, it has a tumult and vigour that shouts one down. It shouts one down, if shouting is to carry it. What good was it to trot along the pavement through this noise and tumult of life, pleading Utopia to that botanist? What good would it be to recommend Utopia in this driver's preoccupied ear? There are moments in the life of every philosopher and dreamer when he feels himself the flimsiest of absurdities, when the Thing in Being has its way with him, its triumphant way, when it asks in a roar, unanswerably, with a fine solid use of the current vernacular, "What Good is all this--Rot about Utopias?" One inspects the Thing in Being with something of the diffident speculation of primitive man, peering from behind a tree at an angry elephant. (There is an omen in that image. On how many occasions must that ancestor of ours have had just the Utopist's feeling of ambitious unreality, have decided that on the whole it was wiser to go very quietly home again, and leave the big beast alone? But, in the end, men rode upon the elephant's head, and guided him this way or that.... The Thing in Being that roars so tremendously about Charing Cross corner seems a bigger antagonist than an elephant, but then we have better weapons than chipped flint blades....) After all, in a very little time everything that impresses me so mightily this September afternoon will have changed or passed away for ever, everything. These omnibuses, these great, stalwart, crowded, many-coloured things that jostle one another, and make so handsome a clatter-clamour, will all have gone; they and their horses and drivers and organisation; you will come here and you will not find them. Something else will be here, some different sort of vehicle, that is now perhaps the mere germ of an idea in some engineer student's brain. And this road and pavement will have changed, and these impressive great buildings; other buildings will be here, buildings that are as yet more impalpable than this page you read, more formless and flimsy by far than anything that is reasoned here. Little plans sketched on paper, strokes of a pen or of a brush, will be the first materialisations of what will at last obliterate every detail and atom of these re-echoing actualities that overwhelm us now. And the clothing and gestures of these innumerable people, the character of their faces and bearing, these too will be recast in the spirit of what are now obscure and impalpable beginnings.
