Grosso has a PhD in philosophy and describes himself as an "independent scholar and part of an ever growing group of scholars and thinkers critical of the prevailing materialistic view of the world."
Grosso seems to ignore the fact that anecdotal evidence is not scientific and eyewitness testimony in relation to paranormal claims is often unreliable. Skeptical investigator Joe Nickell who has evaluated the reports and Grosso's book noted that his most used source for the levitations was Domenico Bernini's 1722 biography but this was unreliable and open to gross exaggeration as it was published nearly six decades after St. Joseph’s death.
Grosso also endorses a lot of other nonsense and paranormal woo in the book. According to Ben Radford:
Though Grosso's book is indexed and contains hundreds of references, skeptics are conspicuously absent, a predictable but unfortunate omission that might have better grounded his discussion of levitation. The book is also undermined by its endorsement of a hodgepodge of dubious and discredited phenomena ranging from Ted Serios (ably debunked decades ago by James Randi and others) to inedia (claims that people can live without eating through meditation and focus) to reincarnation. Though Grosso avoids the common New Age trap of throwing everything in but the kitchen sink, he comes close, with discussions of near-death experiences, ghosts, demonic possession, out-of-body experiences or astral travel, ESP, consciousness, and so on, most of which have only the most tenuous connection to levitation.
Grosso (not surprisingly) is an advocate of quantum woo. He claims that quantum physics may explain levitation and other paranormal phenomena. In an interview, when he was asked the question, "If you actually look at quantum physics, it only operates on the quantum scale. Do you have some reason to think that quantum physics applies on a human scale?", he replied:
“”Well yes, the quantum physicists themselves. It's a very controversial subject, as I'm sure you know. It might very well serve to explain the phenomenon. So I don't think that this point you make is agreed upon by all physicists. I got an email from Hal Puthoff, another very serious physicist, who said, "You're on the right track with all this speculation, even though they are still speculation, it's certainly worth talking about."
