Excerpt from The American Journal of Sociology, Vol. 14: Bi-Monthly; July, 1908-May, 1909 This outlook fixes two areas as the chief planes of vision for modern science. It foreshadows progressive rearrangement of our knowledge and pursuit of knowledge with reference to these areas. To schedule one of them as primary and the other as secondary would be to relapse into an archaic logic. We have to think of two complex systems of factors at work in every passage of experience. These are on the one hand the acting person, on the other hand the conditions of his activity. That is, as a matter of working necessity we are forced to treat every problem of experience as an affair of the interworkings of two main groups of factors, persons, on the one hand, and the conditions under which personal activity Operates, on the other.
