If, as the writer beheves, personahty is the central problem and the focal point of psychology, there can be few attempts more important than to lay an adequate taxonomic foundation which alone can make possible classification and measurement in this field It was from this general point of view that two dimensions of personahty were isolated by the writer (19) (1) a general factor of neuroticism, classifying people according to their emotional stability, maturity, or integration, (2) a factor of extroversion-introversion similar to that outlined by Janet (33) and Jung (34) Statistical evidence was provided in favor of this hypothesis, and expenmental evidence was given to show that both dimensions could be measured with considerable rehability and validity While this work was m progress, it became increasingly apparent that some clarification would have to be found with regard to the relation of the factors isolated to the main dimensions emerging from Kretschmer's wellknown investigations (38) An attempt to do so will be made in the present series of papers, but before attempting such an integration and the experimental examination of Kretschmer's theorj that such an attempt would require, it will be necessary to give a detailed account of the present state of knowledge with respect to this system
