Howard Eisenberg’s Inner Spaces is a wide-ranging account of parapsychology, first published in 1977 and presented here with a new foreword. Eisenberg begins with the field’s history and vocabulary, then examines reports of telepathy, precognition, apparitions, reincarnation, and psychokinesis. He gives readers a way to follow a subject crowded with overlapping names and claims. His distinction between receptive and expressive forms of “psi” is especially useful because it keeps the discussion organized as the book moves from personal experiences to laboratory studies. The new foreword places that original work alongside Eisenberg’s present concerns about isolation, technology, and environmental damage.

I think the book is strongest when it shows how investigators have tried to study elusive experiences. Eisenberg explains chance expectations, sensory safeguards, blind judging, and the problems posed by interpreting a subject’s impressions. His account of dream experiments and emotionally engaging targets gives the research a human texture that card-guessing trials seldom have. Appendix C offers a close look at his own McGill telepathy study, in which pairs of participants responded to short films and researchers compared their descriptions and photograph rankings. That detailed account lets readers see the choices behind an experiment, including its controls and the difficulty of turning an impression into a result. Throughout, Eisenberg is attentive to the possibility that expectations shape what people notice. As he puts it, “The brain therefore may act as a filter, and moreover, a tunable one.”

From those investigations, Eisenberg develops a larger view of consciousness. He considers whether minds share a deeper connection and whether the brain filters awareness instead of producing it. The later chapters bring that view into medicine, psychotherapy, creativity, sports, and ethics, before a consumer’s guide warns readers about fraudulent mediums and commercial psychic courses. These shifts give Inner Spaces its distinctive character: it’s both a survey of research and an argument about how people relate to one another. Eisenberg calls parapsychology “the scientific exploration of our true inner spaces,” a phrase that captures the personal importance he attaches to the field.

Eisenberg’s commitment also shapes the book’s limits. He often explains experimental procedures carefully, yet some claims about what the findings establish, especially in medicine and psychiatry, extend beyond the evidence described on the page. The original text bears the assumptions and scientific context of its era, while the new foreword makes clear that its central questions still matter to the author. I think readers will get the most from Inner Spaces by attending to both its investigative detail and the ambitious interpretation Eisenberg builds upon it. Its enduring value lies in making the history, methods, and stakes of parapsychology accessible enough for readers to examine those connections for themselves.
