What is the author's tone in Uncommon Therapy: The Psychiatric Techniques of Milton H. Erickson, M.D. by Jay Haley?

The tone of the work is engaging and informative. It is objective and interpersonal. It is not meant to do anything except to impart the truth in a way that makes it so readers will see that Milton Erickson is a wonderful therapist and to convince readers that the kind of approach he takes to individual and family therapy should be used extensively throughout our society. In this sense, the tone is biased and persuasive.
