In every large town enormous buildings are erected for museums, academies, conservatoires, dramatic schools, and for performances and concerts. Hundreds of thousands of workmen,—carpenters, masons, painters, joiners, paperhangers, tailors, hairdressers, jewellers, moulders, type-setters,—spend their whole lives in hard labour to satisfy the demands of art, so that hardly any other department of human activity, except the military, consumes so much energy as this. Not only is enormous labour spent on this activity, but in it, as in war, the very lives of men are sacrificed. Hundreds of thousands of people devote their lives from childhood to learning to twirl their legs rapidly (dancers), or to touch notes and strings very rapidly (musicians), or to draw with paint and represent what they see (artists), or to turn every phrase inside out and find a rhyme to every word. And these people, often very kind and clever, and capable of all sorts of useful labour, grow savage over their specialised and stupefying occupations, and become one-sided and self-complacent specialists, dull to all the serious phenomena of life, and skilful only at rapidly twisting their legs, their tongues, or their fingers. But even this stunting of human life is not the worst. I remember being once at the rehearsal of one of the most ordinary of the new operas which are produced at all the opera houses of Europe and America. I arrived when the first act had already commenced. To reach the auditorium I had to pass through the stage entrance. By dark entrances and passages, I was led through the vaults of an enormous building past immense machines for changing the scenery and for illuminating; and there in the gloom and dust I saw workmen busily engaged. One of these men, pale, haggard, in a dirty blouse, with dirty, work-worn hands and cramped fingers, evidently tired and out of humour, went past me, angrily scolding another man. Ascending by a dark stair, I came out on the boards behind the scenes. Amid various poles and rings and scattered scenery, decorations and curtains, stood and moved dozens, if not hundreds, of painted and dressed-up men, in costumes fitting tight to their thighs and calves, and also women, as usual, as nearly nude as might be. These were all singers, or members of the chorus, or ballet-dancers, awaiting their turns. My guide led me across the stage and, by means of a bridge of boards, across the orchestra (in which perhaps a hundred musicians of all kinds, from kettle-drum to flute and harp, were seated), to the dark pit-stalls. On an elevation, between two lamps with reflectors, and in an arm-chair placed before a music-stand, sat the director of the musical part, _bâton_ in hand, managing the orchestra and singers, and, in general, the production of the whole opera.
