¹² In my part of the country, if you set the common man a problem like that of Columbus and his egg, he says, ‘There is no art in that, it is only science’: i.e. you can do it if you know how; and he says just the same of all the would-be arts of jugglers. To that of the tight-rope dancer, on the other hand, he has not the least compunction in giving the name of art.
