The problem is an ancient one: that of determining the qualities of men with reference to their fitness for the work of the world. The general problem precedes the special one alike in theory and in practice. The earliest solutions were in the nature of ambitious attempts to read the ear-marks of mental ability in outward signs; under the incentive of the growth of science these gave way to such systems as phrenology and physiognomy. Such revelations, decisive if sound, proved to be vain hopes or hopelessly irrelevant. The impressionistic verdicts gained from actual experience reflected the cumulative acumen of discernment which ever was and remains the issue of wisdom, empirical but authentic. It furnishes suggestive clues to investigation and a check upon its results. The problem came to its own when the modern science of psychology gave it its setting in the rapid accumulation of knowledge and technique for the interpretation of mental qualities. It at once established the futility of ambitious leads and the necessity of careful, patient and discerning analysis. The present volume surveys the field of attained results and the method of their attainment, in this engaging research.
