who has given the concept of functional alternatives
Robert K. Merton According to Merton's perception of "functionalism", all standardized social and cultural beliefs and practices are functional for both society as a whole as well as individuals in society. This outlook maintains that various parts of social systems must show a high level of integration, but Merton argues that a generalization like this cannot be extended to larger, more complex societies. The second claim has to do with universal functionalism. This claim argues that all standardized social and cultural structures and forms have a positive function. Merton argues that this is a contradiction to what is seen in the real world; not every structure, idea, belief, etc., has positive functions. The third claim of functional analysis that Merton argues with is that of indispensability. This claim states that the standardized parts of society have positive functions, and also represent indispensable parts of the working whole, which implies that structures and functions are functionally necessary for society. Here, Merton argues, people must be willing to admit that there exist various structural and functional alternatives within society.[22]
