ABSTRACT
Historically, the problem of suggestion has been approached along two distinct paths. Up to quite recent times our knowledge of it has been a secondary result of the study of hypnosis: during the last few years the line of investigation has been that of mental analysis. There can be no doubt that the latter form of inquiry is likely to be the more fruitful of the two. In the work of Morton Prince we have both lines of investigation developed in a very successful way.
