Man's conduct and values are circumscribed by society. He plays the role selected for him by society and appropriates his limited categories of values from a niche that society carves out for him. Both his status and mobility are incidents in a dynamic social process of which he is an active partner in the limited universe that niggardly nature and doxial destiny have chosen for him. This dynamic process embraces both social continuity and social change and involves the concept of time.
