What is concept of Power in Sociology

In sociology power is defined as the ability of an individual or group  to fulfil its desires and implement its decisions and ideas.It involves the ability to influence as well control the behaviour of others even against their will.According to Giddens power must be recognized as a primary concept in sociological analysis.It  is potentially an aspect of all relationships.Power is an aspect of all areas of society and all institutions.Talcott Parsons defines power as a systems property a capcity to achieve ends whereas Mills viewed power as a relationship in which one side prevailed over the other. According to Max Weber power is a chance of man or men to realize their own will in a communal action even against the resistance of others who are participating in the action.Marxian analysis rejects the view that power is societal resource held in trust and directed by those in authority for the benefit of all.Instead power is seen to be held by a particular group in society at the expense of rest of the society.The source of power in society lies in the economic infrastructure and gradually the power of the ruling class extends beyond specific economic relations and prevades the entire superstructure.
