That's even worse for Dylan if he wrote it. It's got more cliches than the first two pages of a Harry Potter book. And such hackneyed expressions in such number are typically a dead giveaway that a professional ghostwriter or editor had been involved and wrote it from interview tapes with the rambling subject, as most such things are concocted. You have no evidence that Dylan wrote it other than the statements in Newsweak magazine, which we here otherwise dismiss as lying MSM, and neither do I. Based on this excerpt, I say he didn't.
I will bow to your expertise in literary criticism.
