My project is an investigation into responsibility. In modern times more and more people are getting reduced prison sentences due to diminished responsibility. This inspired me to look into the autonomy of the Subject. This investigation charts its way through the history of the subject, starting with the wholly autonomous subject as proposed in John Rawls theory of justice, justice as fairness. This theory relies on respect for others, freedom and equality and most importantly an autonomous self. The first person to challenge this idea concerning the self was Sigmund Freud when he proposes that the mind was in fact split in three parts, the id, ego and the super‐ego, which all have different effects on our actions and choices. With this theory in mind I look into scientific evidence to back up Freud and show how illness such as schizophrenia and narcissistic personality disorder affect the mind and the Subject. Finally I look at the theories of Keith Ansell Pearson in his book Viroid Life in which he questions the autonomy of the Subject altogether. He produces a theory of the cyborg and the hybrid self and proposes that the rapid rise in technology has created a more deterministic reality and halted the autonomy of man.
