The Ghost In Hamlet plays a vital role not only in developing the Plot of the play but also in displaying a moral order. The Queen does not see the Ghost but Hamlet sees it. In this way it symbolizes
the affinity between father and son, and the absolute breach that has taken place between husband and wife. The fact that the Ghost is invisible to the Queen suggests a moral implication. The Queen is unable to receive spiritual visions because she has deviated from the path of honour and chastity by her illegal remarriage with Claudius. The Ghost also symbolizes the power of the unseen world and messenger of the divine justice. It reminds us that earthly power or glory is controlled and shaped by a spiritual power beyond the jurisdiction of man.
