To illustrate my argument I would like to base my argument pertaining to the post modern shift in ethical notions upon an example of the emerging notion of "expert professionalism" in sociological terms. Take the example of modern professional ethics.
Steven Brint (1994), a sociologist, has referred to the notion of professionalism and ethics as "social trustee professionalism," which banks on the notions of the professionals being aware of their social contract with the larger society. For Brint (1994) the conclusion is that the past decades have seen "a key historical change" in a transition from what was initially "social trustee professionalism" to what is the modern day "expert professionalism". This view is shared by Sullivan (2004:28) who has termed this transition in professionalism as the loss of "the ethical-social values of professional identity".
