By analyzing the multi-dimensional space in Life and Times of Michael K from Lefebvre's space theory, that is, social space, physical space and mental space, this thesis explores identity construction of Michael K. It contends that Michael K's identity develops from being oppressed and confined to the final awakening. Through the portrayal of Michael K, Coetzee sheds light on the predicament of the underclass in an alienated world against the backdrop of war and apartheid in South Africa, inspiring those facing oppression to find a positive life direction through free choice and action.
