Resolving the Identity of Odysseus: 
A journey of self-discovery through the breaking of oneself.
                        …I can see it now
            Your ship destroyed, your men destroyed as well.
            And even if you escape, you’ll come home late
            And a broken man-- all shipmates lost,
            Alone in a strangers ship--
(The Odyssey, by Homer, trans. Robert Fagles, p. 253, book XI, line 127-31)
This  is one of several mentions of Odysseus returning home a broken man.  There are different ways we could interpret this ‘break’. Literally, he  could come home with broken appendages. Psychologically, he could come  home with post-traumatic stress. Amnesia would very well be a form of  breaking a man. Although, Odysseus is referred to twice as “looking for  all the world like an old and broken beggar” (Odyssey,  book XVII, line 220 and book XXIV, line 173) this points out that he  does not suffer a physical or literal break, these are merely illusory  aesthetics.
There are certain clues, however, that illustrate a cognitive break. The fact that you is italicized in the passage contributes to this. Even if you escape death, you won’t escape ego-death. Taken this way who he is  will be broken and he will no longer be the man he was before. The most  dramatic example of a complete ego change that comes to mind is of  Phineas Gage. After surviving an accidental shot through the skull with a  railroad spike his personality shifted dramatically. The resulting  personality was a super-aggressive and angry individual who was no  longer, in essence, the person he once was. But what could cause such a  change in a person lacking the intense environmental pressure of  deforming one’s brain? 
To  understand what, how, and to what degree changes affect a person’s true  character we have to identify what qualities determine someone’s true  identity. This is more than just a name or even the qualities of the  person’s “soul”. Other factors go into discerning the person’s being.  The combination of all these factors is what truly defines a person and  indicates what actions the person is potentially liable to take. It is  these three items that determine the identity of a person:
- Environment and how it influences and dictates your actions.
 - Past decisions, observations, and the consequences of previous actions.
 - The present cognition of a person or the deciding mind. The true ego.
 
Environment  is the one factor which we have the most and least control. Environment  is something that certain individuals can choose and manipulate.  However, environment also indiscriminately hurts and destroys.  Environment will never be fully under our control. As such, we cannot  choose invariably what consequence any location has upon us, but we can  understand the general process that follows our  actions in a given location. That is why Achilles could determine his  two diverging fates in relation to two clear locations. He could stay in  Troy and die young, or return to Phthia to live a long life. Odysseus,  likewise, depends on being in Ithaca to become the person he longs to  be, The King of Ithaca, and all that it entails to be king of Ithaca  (family, land, and title). 
We  see throughout the Odyssey many transformations the environment forms  in the labels given to Odysseus. From king before leaving for the war in  Ithaca, to commander in the Achaean army at Troy, to admiral of a fleet  on the journey home, to captain of a single ship lost at sea, to an  estranged sailor held captive, to guest in Phaeacia, and broken beggar  in Ithaca, eventually back to King of Ithaca. His present or temporary  character changes to accommodate the environment, but we see a lasting,  gradual change developing in his true character. As the story progresses  he puts less emphasis on his name and his actions and begins to  appreciate how much environment plays in who he is. He longs to return  to the person he would be in Ithaca. But  after being estranged so long the past, carrying previous identities  and environments, start to convolute his perception of who he really is.  
The  prophecy Tiresias gives to Odysseus helps bring clarity to his journey  by presenting the fruition of his true identity with one last voyage in  which Odysseus will
            “Carry your well-planted oar until you come
            To a race of people who know nothing of the sea,
            Whose food is never seasoned with salt, strangers all
            To ships with their crimson prows and long slim oars,
            Wings that make ships fly. And here is your sign—
            Unmistakable, clear, so clear that you cannot miss it:
            When another traveler falls in with you and calls
            That weight across your shoulder a fan to winnow grain,
            Then plant your bladed, balanced oar in the earth
            And sacrifice fine beasts to the lord the god of the sea,”
(Odyssey, p. 253, book XI, lines 139-48)
Overcoming  environmental challenges, the past, and imposter identities is the  break that will ultimately define who he truly is and present an  opportunity to finally become who he wants to be. Then true ego-death  occurs and with it a transformation into the person longed to be. But  before he can shed his past identity he must first slaughter the  suitors. This is a symbolic illustration of Odysseus overcoming his  imposter identities. The suitors lived in his house and ate his  food. In book XXII, lines 151-61, we see the suitors even steal and put  on his own armor, spears, and shields. As Achilles had to fight Hector  wearing his own armor, Odysseus had to fight the suitors who wore his own as well. Each represents a symbolic battles over one’s own self. 
Even  after overcoming the environmental problems and the false identities,  he must still overcome his past to achieve ego-death. It’s only after  the trip to bury the oar, the tool Odysseus can identify most with  throughout his long journey, that he can begin to bury the identity that  he had entrenched as himself. In doing this Odysseus can get closure of  his past life and shuffle off the identity that no longer has meaning  in the world he has arrived. 
To  effectively overcome the past a sacrifice of one’s old ego is required,  but this is a hard task to pursue and accomplish. It is essentially  saying that there are potential versions of you who could result from  your present actions and your present self is not worthy of receiving  the life to come, because the current you is an imposter identity to  your ideal ego. It’s a grand gesture of self-sacrifice to move past you to produce something better than yourself. It would be as if in Prometheus Bound  Prometheus had given the choice to mankind of whether or not to be  destroyed so as to make way for a greater race and mankind chose to  actually sacrifice themselves so that the greater race may begin. With  ego-death you are essentially giving up who you have become so that some  stranger  may live instead of you. This is the ultimate form of altruism. To  sacrifice yourself for the masses is relatively easy. To sacrifice  yourself for a singular individual is the pinnacle of selfless acts. 
But this stranger that lives instead of you is  you. You become a stranger to yourself. As a stranger your actions  become hard for you to predetermine. It is at this point that one would  assume the environment and past would play the largest role in defining you,  but those just seem to further muddle the essence of you. You are not  merely your past and your environment. There is a willful beast at the  heart of you. As a stranger to your actions, however, you can observe  the actions you do make objectively. This knowledge of oneself gives an  opportunity to see the motives behind our actions. With this we can  acknowledge who we really are by dispensing of the means and ends which  conflict with who we want to be—our ideal selves.
But  identifying what we don’t want to be does not elucidate exactly who we  should be. This lack of clarity into what identity should follow makes  this transformation a scary and lamenting ordeal, even if it is the  pinnacle of desire. There was a certain level of comfort in the  non-ideal world which the characters had become accustomed. Penelope  describing her dream in book XIX, lines 605-624 illustrates this point  with the sadness she suffers over the slaughter of her geese. She had  begun to define herself in large part with the presence of the suitors  that flooded her home, and the removal of these suitors, while  fulfilling her desires, was jarring to her defined identity. This also  helps explain Odysseus’ actions in being so coy with his family, mainly  Penelope and Laertes. Once the veneer of who you were is removed, there  is an emptiness of character that is hard to instantly fulfill. The  stranger Odysseus becomes enables him to use deception as a defense  mechanism to protect himself from this identity he has lost in an  attempt to try and feel out how this environment will impact his newly  unfolding ego. 
But  who Odysseus becomes from here remains to be seen. This return home  cost him a large part of himself. But to fill this void he is given a  great amount of freedom. The limits constraining his evolving ego are  now confined to the limits of his ideals and imagination.
