Difference between psychological egoism and enlightened ethical egoism

  Explain the difference between psychological egoism and enlightened ethical egoism In 500 words or more (no less), explain the difference between psychological egoism and enlightened ethical egoism. You may use examples, but you will still need to include a full scholarly definition of each, with commentary. You may use any scholarly source other than a dictionary, to include online video lectures. You may use Wikipedia as a starting point, but be aware that Wikipedia is not a scholarly source and therefore can never be quoted in your paper or counted as 1 of your 5 bibliographic citations. You will need to include inline citations in your essay (last name, date, pg#) and must still cite any sources beyond the five required that you use to write your paper in the references section of your essay. If you include an inline citation, there must be a corresponding entry in the reference list or bibliography.
