Shortly after the 1954 publication of Joseph Fielding Smith's Man, His Origin and Destiny, BYU History professor Richard D. Poll and his wife were invited to discuss the book with the author. Knowing that President McKay disagreed strongly with the book, they managed to arrange a meeting with him on the same day. According to the Polls' combined notes, made immediately afterwards, President McKay, "striking the desk for emphasis ... repeated that [Man, His Origin and Destiny] is not the authoritative position of the Church."
