Discuss the role of castes in Hinduism. Why are they there from an emic perspective? How do emic reasons relate to etic critiques?

Caste System-Emic&Etic Aspects

Very interesting question.Not many may be competent to answer this question as the Caste Spirit,by its own nature makes the adherents to believe in what they want to believe.I was a member of Caste System earlier and so competent to answer on the emic http://perspective.In addition,I have been studying the Caste System from the etic perspective for quite some time.My extensive answer Athi S Sundar's answer to Why do Indians behave differently compared to all others? is an etic approach to the issue of caste.The emic perspective is summed up in my answer Athi S Sundar's answer to Why can't we abolish the caste system altogether?and Athi S Sundar's answer to What are the economic implications of caste system?.Hope it helps.
