📚 ABOUT THE BOOK

Upton Sinclair proves telepathy exists through rigorous, scientific experiments with his wife.

While best known for social reform, Sinclair turned his analytical mind to the paranormal.

By sealing drawings in envelopes and measuring transmission accuracy, they amassed irrefutable data proving the mind can broadcast and receive thoughts. This work bridges literature and occult science, documenting a pivotal moment in parapsychology where empirical method met metaphysical mystery.

Fun fact
Sinclair’s greatest triumph here is methodological clarity. He avoids mystical vagueness, offering instead cold, hard data that shocks the rationalist. It sits uniquely in the field, bridging the gap between literary memoir and laboratory report. Skeptics may dismiss the premise, but the experimental design is too compelling to ignore. A essential artifact for any collection dedicated to the history of the paranormal.

📝 Description: Mental Radio (Russell Targ Editions) Sinclair, Upton

Upton Sinclair is primarily known as the Pulitzer Prize-winning author of The Jungle, Oil, and Dragon's Teeth, and as a fiery advocate of social justice and reform. Few know, however, of Sinclair's deep interest in, and connection to, psychic research. Sinclair's own wife, Mary Craig Kimbrough, claimed to have "mind reading" or telepathic abilities, and asked Sinclair to help her better understand these abilities. He devised a fascinating series of 300 tests that incontrovertibly proved the reality of telepathy while revealing the vast, untold powers of the mind. In one room, Sinclair would make a drawing and place it into a sealed envelope, while in another, Mary would "tune in," retrieve the image, and make her own copy. Or she would record a telepathic message sent from someone far away. Her accuracy rate was astonishing, leaving no room for random chance as an explanation, as they continued to collect scientific data over three years. In Mental Radio, Sinclair describes remarkable experiments, comparing telepathy to radio broadcasting, with one brain sending out a "vibration" and another picking it up. The results convinced Sinclair that telepathy is real, that it is unaffected by distance, that it can be cultivated, trained and--most importantly--can be verified and studied scientifically. For the first time in many years, here is the complete text of Mental Radio, including Mary Craig Kimbrough's well-tested instructions on how to learn the "art of conscious mind-reading." Here is the classic book that impressed Albert Einstein who, in his preface to Mental Radio, praises Sinclair for being a conscientious observer and writer and for his good faith and dependability in reporting paranormal research. William McDougall, known as the "Dean of American Psychology" at the time, was so inspired by Sinclairs' work that he established the parapsychology department at Duke University, which went on to become, for a time, the country's premier paranormal research institution.

💎 Expert review

💎
Esoterica Books editorial team
Occult literature desk
While this volume provides compelling data on telepathy through Sinclair's rigorous testing with his wife, it may not suit readers seeking mystical narrative or subjective spiritual experiences. The focus remains strictly on empirical validation and experimental accuracy rather than philosophical depth or esoteric tradition. Critics expecting literary flair typical of Sinclair’s social reforms might find the tone dry and technical. However, for those who value parapsychological history and the application of scientific control to paranormal claims, it stands as a significant document. It is best approached as a case study in evidence gathering rather than a guide to occult practice or a philosophical treatise on consciousness.

Good addition to the shelf

Long-time student of the esoteric here. Every rereading turns up something I missed. It rewards patience more than any book I've bought this year. A few pages arrived with light corner wear, though nothing serious. Still worth having on the shelf.
