In his work Beckett Recognizes three sources of human alienation. First is the alienation of the individual from society; his characters are mostly outcasts or at least
isolated from human society. Second, his characters are also alienated from themselves; the mind/body split is a constant theme in his work, the difficulty in reconciling the potential beauty of existence, which is revealed through the mind, and the inevitable suffering and decay of the body. And this leads to the final and overarching issue, the alienation of human beings from. their destiny: We are born to die, a fact that we can neither explain nor escape from. The inexorable passage of tine through an infinite space is the frame for all of Beckett's work.
