According to Steven Poole review of this book.
The book is a shatteringly glib mishmash of magazine yarn, bizarrely incompetent literary criticism, inspiring business stories about mops and dolls and zany overinterpretation of research findings in neuroscience and psychology.
More recently, Lehrer admitted fabricating quotes by Bob Dylan in Imagine, which was hastily withdrawn from sale, and he resigned from his post at the New Yorker. (see more of this on this article)
To invent things supposedly said by the most obsessively studied popular artist of our age is a surprising gambit. Perhaps Lehrer misunderstood his own advice about creativity.
I tend to agree with the above review.
