„The rule that you not use words that were first uttered or written by another without due attribution is less like the rule against stealing, which is at least culturally universal, than it is like the rules of golf. I choose golf because its rules are so much more severe and therefore so much odder than the rules of other sports. In baseball you can (and should) steal bases and hide the ball. In football you can (and should) fake a pass or throw your opponent to the ground. In basketball you will be praised for obstructing an opposing player’s view of the court by waving your hands in front of his face. In hockey … well let’s not go there. But in golf, if you so much as move the ball accidentally while breathing on it far away from anyone who might have seen what you did, you must immediately report yourself and incur the penalty. (Think of what would happen to the base-runner called safe at home-plate who said to the umpire, “Excuse me, sir, but although you missed it, I failed to touch third base.”)
Golf’s rules have been called arcane and it is not unusual to see play stopped while a P.G.A. official arrives with rule book in hand and pronounces in the manner of an I.R.S. official. Both fans and players are aware of how peculiar and “in-house” the rules are; knowledge of them is what links the members of a small community, and those outside the community (most people in the world) can be excused if they just don’t see what the fuss is about.
Plagiarism is like that; it’s an insider’s obsession. If you’re a professional journalist, or an academic historian, or a philosopher, or a social scientist or a scientist, the game you play for a living is underwritten by the assumed value of originality and failure properly to credit the work of others is a big and obvious no-no. But if you’re a musician or a novelist, the boundary lines are less clear (although there certainly are some) and if you’re a politician it may not occur to you, as it did not at one time to Joe Biden, that you’re doing anything wrong when you appropriate the speech of a revered statesman.”
