The very interesting research work of Bernard D. Beitman, MD. About emerging field of coincidence studies, such as the synchronicities that occur to us at crucial times, that have important meaning and that can impact us to transform our lives, and even to save our lives or those of our loved ones.
We can find interesting information from serious research in psychiatry, psychology and probability theories that can explain this phenomenon, without ruling out the belief of many people that they are a guide and help of a superior intelligence. The second part describes the essential characteristics to occur, the factors and the necessary mental state that allows us to experience them more frequently.
Finally in the third part he talks about a more novel and fascinating theory about the existence of a Psychosphere, "interconnection of all things, a densely woven mental web", and that extends the concept of Jung's collective unconscious. The author explains that our senses are not completely understood by science, and with that premise invites us to consider that there can be subtle energies emanating that we are able to perceive. There is a possibility that we have receptors for a rich variety of energies and that our brain is capable of processing those forms of information. These different receptors can be based on ancestral mechanisms that have evolved in other living beings, we have inherited them and we are recognizing them again.
(This reminds me that in 1980 the zoologist Robin Baker published the Manchester Experiments where he wanted to test the ability of humans to orient themselves and perceive the electromagnetic fields of the Earth. In addition more recent discoveries can support these hypotheses, like the presence of magnetite in our brain and bones; and cryptochromes in our eyes that participate in the magnetoreception of some animals).
In general, the subject of the book is still on the frontier of unexplained mystery, psychological theories and little scientific documentation, may be mainly because we do not know more than we know and the limitations of having more sensitive measuring instruments. It should not be forgotten that the scientific method is hypothetical-deductive based on reproducibility and refutability. The results of modern science depend on measurement procedures, there are still many disagreements in the set of tactics used to constitute knowledge and are subject to future discoveries.
Faced with this scenario, the fact that there is no conclusive scientific data, this does not discard that the phenomenon exists. The collaboration of Bernard Beitman seems to me to be a pioneer since he is the first psychiatrist since Carl Jung to use a systematic method for the study of coincidences. The work presented here was very interesting, I think it has a significant value, although not definitive, and that in the near future can throw relevant data to better understand the human psyche.
My gratitude to the Publisher and NetGalley for allowing me to review the book
