ABSTRACT
The concept of the mind has been studied from many perspectives: traditionally as part of religion and philosophy, in modern times having been directed towards psychology and more recently, neuroscience. The Austrian psychologist, Sigmund Freud, took great interest in the function of the mind, especially the unconscious, came to revolutionise what up until then had been a quite narrow understanding of its make-up. Carl Gustav Jung came to believe that something in Freud's model was missing and as his research into schizophrenia progressed, he started questioning the assumption that the human mind develops from a blank slate, tabula rasa, at birth. The view of the unconscious mind is not so much any longer whether it is involved in cognitive activities or not but rather how and how much. What has since become the leading mind theory is the dual process theory, which assumes that human thinking consists of two distinct parts that interact in tandem and form a holistic structure.
