Can anyone speak a language he or she has not learned normally, in childhood or later? Claims to have accomplished this are made from time to time, but only rarely do they receive support when carefully examined. In this volume, Dr. Stevenson presents detailed reports of two cases that seem authentic.

Authentic instances of speaking a language that has not been learned normally (responsive xenoglossy) suggest that another personality (perhaps one of a previous life) had learned the langauge. Cases of responsive xenoglossy thus add to the evidence concerning the survival of human personality after death.
