the action should take place in a minimal number of locations These three unities have been considered necessary to create credibility in a play The Unity of Action The unity of action is an organic unity which gives the form and meaning of a tragedy Aristotle lays more emphasis on the unity of action He says Tragedy then is a representation of an action that is worthy of serious attention complete in itself and of some amplitude It indicates that the action must be complicated Now a whole is that which has a beginning middle and an end The beginning must not necessarily follow some previous situation There must be an earlier part of the story The beginning must be clear and intelligible It is neither too long nor too short in size Then the middle is consequent upon a situation that is connected with the beginning And finally the ending which is followed by nothing The Unity of Time The unity of time is the second of three unities Unity of time refers to the action of a play should occur within a single circuit of the sun The action does not continue for more than hours Aristotle says In an epic there is no fixed limitation of time whereas tragedy endeavors to keep as far as possible within a single circuit of the sun or something near that According to Aristotle spectators will not believe in the reality of action if a drama lasts more than a single day If the spectators remain disbelieving in the action of a tragedy it will fail to arouse fear and it will be futile Unity of Place Unity of place means that a play's action is confined to a single physical location Aristotle argued that this would enhance the plausibility of the story and maintain the audience's immersion in the narrative By restricting the setting the playwright can focus on the characters' interactions and the development of the central conflict without the distraction of changing scenes and locations From the above discussion it is clear that these three unities are essential to a successful tragedy Aristotle mentions their formative unities by considering his own at the time But he emphasizes the unity of action and says it is the controlling law of a drama nbsp
