This is one of the oldest and most intriguing subjects there is and a real bugaboo to rational science. Ullman et al., have been doing their best to spruce it up in the laboratory and, now, to legitimize it in print with a survey of past investigations and spontaneous evidence, along with samplings from their own research (mostly at Maimonides Hospital, New York, and to be continued in the new Gardner Murphy Institute). They write for laymen not especially predisposed -- that helps -- and with a degree of genial skepticism when appropriate, e.g., the good and gullible Dr. Ermacora, c. 1890, who looked to the day when reading would be taught telepathically. The Maimonides experiments involved the transmission of art reproductions under carefully circumscribed conditions (such criticisms as can be made of the design appear in an appendix, and they are not particularly commanding) and yielded favorable results with odds of about 1000 to 1 -- this discounting some astonishing accidental communications that cast doubt on the very possibility of scientific control. If the authors had been free to pursue their interpretations along broader, more psychoanalytic lines the findings might have been even more striking (readers can do a bit of this for themselves from the transcripts) but this would have been clinically invalid as well as compromising to their subjects. Creepy enough for devotees, sound enough to trouble everyone. With notes and much supplementary back matter.
