 So that's one class of work. The second class of work is works whose purpose is to say what certain people think. Talking about those people is their purpose. This includes, say, memoirs, essays of opinion, scientific papers, offers to buy and sell, catalogues of goods for sale. The whole point of those works is that they tell you what somebody thinks or what somebody saw or what somebody believes. To modify them is to misrepresent the authors; so modifying these works is not a socially useful activity. And so verbatim copying is the only thing that people really need to be allowed to do.
