This thesis examines the theme of robot rebellion in SF narrative as an incarnation of Hegel’s Master/Slave dialectic. Chapter one analyzes the depiction of robot rebellion in Karel Capek’s R.U.R. Chapter two surveys posthuman theory and offers close readings of two contemporary SF television series that exemplify ontologically progressive narratives. The thesis concludes that posthuman subjectivity sublates the Master/Slave dialectic and encourages practical posthuman ethics.
