People are so insecure and neurotic about their ‘material.’ It’s not your material. You got it from a thousand places, the person who uses it is going to take it in a thousand directions. Everyone should just chill out. I thought that Jonah Lehrer was sloppy and made mistakes and all that, but the real question is: Did you read his books and learn something from it? If you did, who cares whether the Dylan quote had that precise wording or had a slightly different wording? I don’t know, I just don’t have the strength and patience for these kinds of intramural arguments that writers have about whether this precise use of words matched this precise use of words. I’d just much rather answer the question of whether something is being learned, or something interesting is happening.
