The principle of which I speak can be seen everywhere in a comparison between the ancient and universal things and the modern and specialist things. The object of a theodolite is to lie level; the object of a stick is to swing loose at any angle; to whirl like the very wheel of liberty. The object of a lancet is to lance; when used for slashing, gashing, ripping, lopping off heads and limbs, it is a disappointing instrument. The object of an electric light is merely to light (a despicable modesty); and the object of an asbestos stove⁠ ⁠… I wonder what is the object of an asbestos stove? If a man found a coil of rope in a desert he could at least think of all the things that can be done with a coil of rope; and some of them might even be practical. He could tow a boat or lasso a horse. He could play cat’s-cradle, or pick oakum. He could construct a rope-ladder for an eloping heiress, or cord her boxes for a travelling maiden aunt. He could learn to tie a bow, or he could hang himself. Far otherwise with the unfortunate traveller who should find a telephone in the desert. You can telephone with a telephone; you cannot do anything else with it. And though this is one of the wildest joys of life, it falls by one degree from its full delirium when there is nobody to answer you.
