Slaves' Work, or Patience and Sandpaper.

"So the rule is simple: Always look for invention first, and after that, for such execution as will help the invention, and as the inventor is capable of without painful effort, and no more. Above all, demand no refinement of execution where there is no thought, for that is slaves' work, unredeemed. Rather choose rough work than smooth work, so only that the practical purpose be answered, and never imagine there is reason to be proud of anything that may be accomplished by patience and sandpaper.

§ xx. I shall only give one example, which however will show the reader what I mean, from the manufacture already alluded to, that of glass. .Our modern glass is exquisitely clear in its substance, true in its form, accurate in its cutting. We are proud of this. We ought to be ashamed of it. The old Venice glass was muddy, inaccurate in all its forms, and clumsily cut, if at all. And the old Venetian was justly proud of it. For there is this difference between the English and Venetian workman, that the former thinks only of accurately matching his patterns, and getting his curves perfectly true and his edges perfectly sharp, and becomes a mere machine for rounding curves and sharpening edges, while the old Venetian cared not a whit whether his edges were sharp or not, but he invented a new design for every glass that he made, and never moulded a handle or a lip without a new fancy in it. And therefore, though some Venetian glass is ugly and clumsy enough, when made by clumsy and uninventive workmen, other Venetian glass is so lovely in its forms that no price is too great for it; and we never see the same form in it twice. Now you cannot have the finish and the varied form too. If the workman is thinking about his edges, he cannot be thinking of his design; if of his design, he cannot think of his edges. Choose whether you will pay for the lovely form or the perfect finish, and choose at the same moment whether you will make the worker a man or a grindstone."
