William Isaac Thomas,
The Unadjusted Girl, With Cases and Standpoint for Behavior Analysis
“ A social institution can be understood and modified only if we do not limit ourselves to the study of its formal organization but analyze the way in which it appears in the personal experience of various members of the group and follow the influence which it has on their lives. And an individual can be understood only if we do not limit ourselves to a cross-section of his life as revealed by a given act, a court record or a confession, or to the determination of what type of life-organization exists, but determine the means by which a certain life-organization is developed. ”
