The separation and retention of the right to copy from the bundle of rights that we call property is problematic. Could one reserve the right, for example, to remember something? Suppose that I wrote a book and offered it to you to read, but I had retained one right: the right to remember it. Would I be justified in taking you to court if I could prove that you had remembered the name of the lead character in the book?
