Other issues are not of importance as they remain based on the interaction of people. This is considered to be a 'bottom up' approach where sociologists of this theory are actually micro sociologists. They hardly have any interest in institutions or structures. They are totally unconnected with the rigid framework or conflicts of society. This is an entirely different theory purely based on human interactions. It is in no way connected with the other theories. They say that change is a dynamic feature of the society and interaction brings change into it. According to this theory, change is constant and it is not the result of a few conflicts. Change is a continuous process. Conflicts might happen once in a way, and the result could be violent or unexpected. Repercussions might go out of hand and might not happen in the way it was presumed. Change cannot depend on spurts of conflict and then go cold again waiting for another such conflict. Future of the human society depends on present and future social interaction while its foundation rests on past interaction. These interactions decide the nature and development of human society. Society is created by people who live and act in it and there is no society without human interaction. The social institutions that are so highly respected by functionalists are merely human creations at every stage of societal evolvement. On the whole this theory is appreciated by most of the sociologists. As this theory is based on human interaction, this is a very useful theory in social research, family research and psychological researches. Human interaction being a very pertinent field of human development, it is necessary to understand a human being from the perspective of his social abilities and interactions with family members, peers, colleagues or with the larger society. This shows the importance of Man, who is supposed to have related to herd mentality in earlier days, as a part of societal relationships and this theory has given many variables dependent and independent both, to psychologists and family sociologists.
"From the standpoint of a sociological theory of the family this premise asserts investigations of a familial role expectations as a dependent variable, or studies which relate to familial role expectations as independent variable to the structure of the self as dependent variable as incomplete," Striker (1968, p.558).
Without human interaction with one another, according to this theory, there is hardly any growth or change in society. This means, isolated humans will not be able to bring in any change or conflict into society. They simply live their isolated lives in blissful loneliness. At the same time, it is impossible to live in total isolation. Well, we all have heard of Robinson Crusoe, but we also know that he continuously had tried to reach back the civilisation. He did not stay back in the island, defying the civilised world, because he needed societal interaction and the comfort of sharing life with others.
Alfred Schultz theory of 'the common sense world'
Alfred Schultz belonged to the Austrian school and is widely appreciated for having tried "a highly original and complex synthesis between the interpretive philosophy of Max Weber, the phenomenology of Edmund Husserl and elements of the thought of
