Y.M. The steam-engine? O.M. It takes fifty men a hundred years to invent it. One meaning of invent is discover. I use the word in that sense. Little by little they discover and apply the multitude of details that go to make the perfect engine. Watt noticed that confined steam was strong enough to lift the lid of the teapot. He didn’t create the idea, he merely discovered the fact; the cat had noticed it a hundred times. From the teapot he evolved the cylinder—from the displaced lid he evolved the piston-rod. To attach something to the piston-rod to be moved by it, was a simple matter—crank and wheel. And so there was a working engine. One by one, improvements were discovered by men who used their eyes, not their creating powers—for they hadn’t any—and now, after a hundred years the patient contributions of fifty or a hundred observers stand compacted in the wonderful machine which drives the ocean liner. Y.M. A Shakespearean play? O.M. The process is the same. The first actor was a savage. He reproduced in his theatrical war-dances, scalp—dances, and so on, incidents which he had seen in real life. A more advanced civilization produced more incidents, more episodes; the actor and the story-teller borrowed them. And so the drama grew, little by little, stage by stage. It is made up of the facts of life, not creations. It took centuries to develop the Greek drama. It borrowed from preceding ages; it lent to the ages that came after. Men observe and combine, that is all. So does a rat. Y.M. How? O.M. He observes a smell, he infers a cheese, he seeks and finds. The astronomer observes this and that; adds his this and that to the this-and-thats of a hundred predecessors, infers an invisible planet, seeks it and finds it. The rat gets into a trap; gets out with trouble; infers that cheese in traps lacks value, and meddles with that trap no more. The astronomer is very proud of his achievement, the rat is proud of his. Yet both are machines; they have done machine work, they have originated nothing, they have no right to be vain; the whole credit belongs to their Maker. They are entitled to no honors, no praises, no monuments when they die, no remembrance. One is a complex and elaborate machine, the other a simple and limited machine, but they are alike in principle, function, and process, and neither of them works otherwise than automatically, and neither of them may righteously claim a _personal _superiority or a personal dignity above the other. Y.M. In earned personal dignity, then, and in personal merit for what he does, it follows of necessity that he is on the same level as a rat? O.M. His brother the rat; yes, that is how it seems to me. Neither of them being entitled to any personal merit for what he does, it follows of necessity that neither of them has a right to arrogate to himself (personally created) superiorities over his brother.
