The quote questions the credibility of those claiming to have discovered ways to manipulate human choice and free will. It highlights the implausibility of someone possessing such significant power choosing to disclose their secrets to the public through an inexpensive book. This notion prompts readers to consider the true intentions behind such revelations, suggesting that anyone with that level of influence would likely keep their knowledge private for personal gain.

Additonally, the quote raises ethical concerns about the idea of monetizing the manipulation of free will. If a person could indeed control how others make choices, revealing this information in a book could be seen as morally questionable. The author, Chris Murray, invites us to reflect on the motivations of those who promise to teach highly valuable secrets and whether such promises are trustworthy or merely a means to profit.
