practical side, they were found to have their cause in the divisions of society into more or less rigidly marked-off classes and groups—in other words, in obstruction to full and flexible social interaction and intercourse. These social ruptures of continuity were seen to have their intellectual formulation in various dualisms or antitheses—such as that of labor and leisure, practical and intellectual activity, man and nature, individuality and association, culture and vocation. In this discussion, we found that these different issues have their counterparts in formulations which have been made in classic philosophic systems; and that they involve the chief problems of philosophy—such as mind (or spirit) and matter, body and mind, the mind and the world, the individual and his relationships to others, etc. Underlying these various separations we found the fundamental assumption to be an isolation of mind from activity involving physical conditions, bodily organs, material appliances, and natural objects. Consequently, there was indicated a philosophy which recognizes the origin, place, and function of mind in an activity which controls the environment. Thus we have completed the circuit and returned to the conceptions of the first portion of this book: such as the biological continuity of human impulses and instincts with natural energies; the dependence of the growth of mind upon participation in conjoint activities having a common purpose; the influence of the physical environment through the uses made of it in the social medium; the necessity of utilization of individual variations in desire and thinking for a progressively developing society; the essential unity of method and subject matter; the intrinsic continuity of ends and means; the recognition of mind as thinking which perceives and tests the meanings of behavior. These conceptions are consistent with the philosophy which sees intelligence to be the purposive reorganization, through action, of the material of experience; and they are inconsistent with each of the dualistic philosophies mentioned.
