Eugene O’Neill’s masterpiece, The Iceman Cometh, is a tragedy on the personal identity rupture in the alternation of value systems. Having been materialized and isolated, the drunkards whose American dreams have shattered are sliding into the abyss of nothingness and absurdness irreversibly. They try to transcend the pain brought by the breaking from the traditional values and sliding into the absurd, but their personal identities rupture in the dislocation of their actuality and desire. On the one hand, facing unwillingly what they actually are, they sketched out a good image they desire in the pipedream, and maintain the harmony between objective and subjective self by selfdeception, thus, their social identities are inclined to rupture. On the other hand, they abandon the fetters and guilty by remo〖JP2〗ving the God, they pursue absolute freedom but they are enslaved by the freedom, thus, in the paradox, they lose their belief, their religious identities are going to rupture. At the end of the play, the revelers realized their refusal to the pain, they refuse the pain but accept the absurdity, in the irrational binge, their identities completely rupture.
