The knowledge of nature and the mastery of nature have always belonged together. - Hugo Münsterberg

WE have placed our psychotechnical interest at the service of economic tasks... The purpose before us was to find for every economic occupation the best-fitted personality, both in the interest of economic success and in the interest of personal development.

The inner labor, the inner values, and the inner difficulties and frictions are too often unknown to those who decide for a vocation, and they are unable to correlate those essential factors of the life-calling with all that nature by inheritance, and society by surroundings and training, have planted and developed in their minds.

Applied psychology can, therefore, speak the language of an exact science ill its own field, independent of economic opinions and debatable partisan interests.
