QUOTE : Applied to the family, the argument suggests that affection and personality cultivation can somehow exist in a social vacuum, unsupported by the determining goals and ideals of economic and political society. But in hard fact no social group will long survive the disappearance of its chief reasons for being, and these reasons are not, primarily, biological but institutional. Unless new institutional functions are performed by a group—family, trade union, or church—its psychological influence will become minimal.
