ABSTRACT
Acceptance of the evidence for two minds (R-mind and L-mind) in the human brain challenges long-held views in a wide variety of fields. The existence of two minds brings with it the existence of two forms of consciousness, two sets of memories, two sets of beliefs and desires, two wills. This must have major implications for those whose work involves the mind and its problems—psychologists, psychiatrists, and neurologists in particular. The ego has been described as the "part of the mind which reacts to external reality and which a person thinks of as the 'self'". The presence of two minds within the human brain, and the complexity of their interactions, necessitates a re-assessment of how responsibility for criminal behaviour should be judged. In many cases, the term unconscious is used of behaviour (i) which the L-mind is unaware of or (ii) where the L-mind is aware of the behaviour but not of the thought processes that brought it about.
