This study analyzes the conceptualization of slavery and freedom in slave narratives. More precisely, it investigates the different conceptual metaphors regarding slavery versus freedom as used by Mende Nazer in Slave. The study also investigates the different autobiographical memory forms as a psychological necessity during autobiographical memory retrieval as well as the notion of social death as an aspect of slavery and their relation to conceptual metaphor. Finally, the study aims at identifying the total self-concept and the associated attributes as unconsciously revealed through the use of CM. It has been found that both FREEDOM AND SLAVERY are conceptualized in terms of JOURNEYS. Nonetheless, the difference between both journeys is that the FREEDOM JOURNEY turns out to be a PSYCHOLOGICAL JOURNEY in which Mende conceptualizes only through imagination. Moreover, it has been concluded that there is a strong tie between conceptual metaphor and autobiographical memory in slave narratives. Additionally, the notion of social death is embedded within the unconscious use of conceptual metaphors in slave narratives. Finally, it has been concluded that the intersection of all three theories; namely, conceptual metaphor, autobiographical memory and social death, helps in the construction of the protagonist's self-concept.
